Evaluación del Compromiso Cardiovascular en niños en diálisis mediante el Índice de Masa Ventricular Izquierdo / Left Ventricular Mass Index and Cardiovascular Compromise in children on dialysis

INTRODUCCIÓN: Existe una estrecha relación entre enfermedad renal crónica (ERC) y enfermedad cardiovascular. Una de sus manifestaciones clínicas es la hipertrofia de ventrículo izquierdo (HVI), expresada como Indice de Masa Ventricular Izquierda (IMVI, gr/m27). En pacientes portadores de ERC con retraso de creci miento, el cálculo de IMVI debería ajustarse corrigiendo la edad para la talla. OBJETIVO: Comparar el IMVI corregido por edad para la talla, con el valor calculado por edad cronológica en niños con ERC en diálisis. PACIENTES Y MÉTODO: Estudio de corte transversal. Se analizan ecocardiografías de pacientes portadores de ERC en diálisis entre 1-18 años, enero de 2016 a julio 2017. Se evalúa IMVI ajustando el valor expresado a gr/m27 al percentil para la edad cronológica del niño, y luego se ajusta el valor a la edad corregida por la talla. Se usa estadística descriptiva y estudio de concordancia para las evaluacio nes de IMVI calculado por edad cronológica y para edad corregida por talla. RESULTADOS: Se incluyeron 26 pacientes, 75 ecocardiogramas. Un 56% presentó HVI usando IMVI calculado por edad cronoló gica vs un 46,6% al corregir la edad para la talla. Al comparar los grupos de percentiles de IMVI-edad cronológica vs IMVI ajustado a la edad para la talla real, se observó que el 18,6% de la muestra cambia de grupo de percentil, el 100% de ellos a un grupo de percentil inferior. La concordancia evaluada en base a coeficiente Kappa fue de 0,72 (concordancia perfecta > 0,8), confirmando diferencias al ajustar el IMVI para la edad corregida por la talla. CONCLUSIÓN: El cálculo de IMVI por edad cronológica so breestima el compromiso cardiovascular en niños con ERC que característicamente tienen un retraso de talla. Los resultados sugieren que el cálculo de IMVI ajustado a la edad corregida por talla otorga mayor precisión al diagnóstico de hipertrofia ventricular izquierda en este grupo de pacientes.

INTRODUCTION: There is a close relationship between chronic kidney disease (CKD) and cardiovascular disease. One of its clinical manifestations is left ventricular hypertrophy (LVH), expressed as Left Ventricular Mass Index (LVMI gr/m27). In CKD patients with growth retardation, the LVMI calculation should be adjusted by correcting age for length/height. OBJECTIVE: To compare the age-corrected LVMI for length/height with the value calculated by chronological age in CKD children on dialysis. PATIENTS AND METHOD: Cross-sectional study. We analyzed echocardiographies of CKD children on dialysis aged between 1 and 18, from January 2016 to July 2017. LVMI was evaluated by adjusting the value expressed in gr/m27 to the percentile for the chronological child's age, and then the value was adjusted to the age-corrected length/height. We used descriptive statistics and concordance study for LVMI assessments calculating by chronological age and for age-corrected length/height. RESULTS: 26 patients were included and 75 echocardiograms. 56% had left ventricular hypertrophy using chronological age versus 46.6% age-corrected LVMI for length/height. When comparing the percentile groups of LVMI-chronological age vs. age-adjusted LVMI for actual length/height, it was observed that 18.6% of the sample changed percentile groups, 100% of them to a lower percentile group. The agreement evaluated based on the Kappa coefficient was 0.72 (perfect agreement > 0.8), confirming differences when adjusting the LVMI for age-corrected length/height. CONCLUSION: Calculating LVMI by chro nological age overestimates the cardiovascular involvement in children with CKD who are charac teristically stunted. The results suggest that the age-adjusted, length/height-corrected calculation of LVMI gives greater accuracy to the diagnosis of left ventricular hypertrophy in this group of patients.

Diabetes and covid-19: more than the sum of two morbidities

ABSTRACT The coronavirus disease 2019 (covid-19) pandemic has caused a public health emergency worldwide. Risk, severity and mortality of the disease have been associated with non-communicable chronic diseases, such as diabetes mellitus. Accumulated evidence has caused great concern in countries with high prevalence of this morbidity, such as Brazil. This text shows the picture of diabetes in Brazil, followed by epidemiological data and explanatory hypothesis for the association between diabetes and covid-19. We emphasized how the burden of these two morbidities in a middle-income country has aggravated this pandemic scenario. The comprehension of this association and biological plausibility may help face this pandemic and future challenges.

Nutrición cardiometabólica en el mundo real de la práctica clínica / Cardiometabolic nutrition in the real world of clinical practice

La importancia de la nutrición en modificar el riesgo de enfermedad cardiovascular aterosclerótica (ECVA) se ha enfatizado repetidas veces. Históricamente, el papel de los componentes dietarios ha sido el foco predominante; sin embargo, los alimentos, típicamente, se consumen en combinación más que aisladamente. En los últimos años, se ha puesto una mayor atención a los patrones dietarios y su relación con eventos clínicos del tipo de la ECVA, diabetes mellitus tipo 2 y obesidad; paradójicamente, existe una brecha en la educación nutricional en las escuelas de medicina de todo el mundo. Por lo general, una dieta no saludable está asociada con alteraciones cardiometabólicas, una condición clínica que, gradualmente, puede empeorar y conducir a diversos factores comunes de riesgo de enfermedades crónicas, a mayor morbilidad y mortalidad y menoscabo en la calidad de vida. El público en general debe satisfacer la cantidad de calorías requeridas con una variedad de alimentos densos en nutrientes que abarquen todos los grupos de alimentos para mantener la salud a largo plazo. El estilo de patrones saludables de comer varía individualmente y frecuentemente refleja las preferencias culturales y personales. Una alimentación no saludable puede causar una elevación de la producción posprandial de insulina e hipersecreción crónica de insulina e hiperinsulinemia, lo cual promueve la acumulación de grasa, previene la lipólisis y causa incremento en el riesgo de desarrollar ECVA, obesidad y diabetes tipo(AU)

The importance of nutrition in modifying the risk of atherosclerotic cardiovascular disease (ACVD) has been repeatedly emphasized. Historically, the role of dietary components has been the predominant focus; however, foods are typically consumed in combinations rather than individually. Over the last few years, increasing attention has been given to dietary patterns and their relationship to clinical events such as ACVD, type 2 diabetes and obesity; paradoxically, there is a gap in nutrition education in medical school around the globe. An unhealthy diet is usually associated with cardiometabolic alterations, a clinical situation that can progressively worse, potentially leading to various common risk factors, increased morbidity and mortality, and reduced quality of life. People should aim to fulfill their recommended calorie intake with a variety of nutrient-dense foods that span all food groups to boost long-term health. Healthy eating styles may vary from individual to individual and frequently reflect cultural and personal preferences. An unhealthy diet may cause a high postprandial insulin production and chronic insulin hypersecretion and hyperinsulinemia, which promote fat storage, prevent lipolysis and cause increased the risk for developing ACVD, obesity and type 2 diabetes

Recomendaciones para la atención de pacientes con insuficiencia cardiaca y COVID-19 / Recommendations for the care of patients with heart failure and COVID-19

Resumen La pandemia por COVID-19 decretada por la Organización Mundial de la Salud (OMS) desde el 12 de marzo de 2020 está produciendo estragos a nivel mundial y es un verdadero reto económico, social y sanitario. Aunque las manifestaciones clínicas del COVID-19 son síntomas respiratorios, algunos pacientes también tienen síntomas cardiológicos. Dentro de los pacientes con afecciones cardiológicas2 suponen un grupo de mayor riesgo y que de hecho son un grupo especialmente vulnerable, por su mayor riesgo de contagio y mayor gravedad en caso de adquirir la enfermedad1 aquellos con insuficiencia cardiaca (IC), incluyendo al trasplante cardiaco (TC) y las asistencias ventriculares, así como los pacientes con hipertensión arterial pulmonar (HAP). La IC es la principal patología cardiovascular crónica y los pacientes en este grupo son los más vulnerables para el desarrollo de cuadros clínicos más graves tras sufrir la infección, y en mayor medida los casos con IC avanzada3. De hecho, la IC es unas de las complicaciones más frecuentes en los pacientes con COVID-194. De igual forma, los pacientes trasplantados que requieren de los inmunosupresores para evitar el rechazo del injerto, constituyen una población especialmente susceptible a la infección y a desarrollar procesos más graves. Esta situación ha hecho que la Asociación Nacional de Cardiólogos de México (ANCAM) y la Sociedad Mexicana de Cardiología (SMC) junto con sus respectivos capítulos, hayan elaborado las siguientes recomendaciones para el personal médico, que participa en la atención de este grupo especial de pacientes en los diferentes escenarios clínicos, que padezcan o no, COVID-19.

Abstract The COVID-19 pandemic decreed by the World Health Organization (WHO) since March 12, 2020 is wreaking havoc globally and it is a true economic, social and health challenge. Although the clinical manifestations of COVID-19 are respiratory symptoms, some patients also have cardiological symptoms. Among patients with cardiological conditions2 they represent a group of higher risk and, in fact, they are a particularly vulnerable group, due to their higher risk of contagion and greater severity in case of acquiring the disease1 those with heart failure (HF), including heart transplant (CT) and ventricular assists, as well as patients with pulmonary arterial hypertension (PAH). HF is the main chronic cardiovascular disease and patients in this group are the most vulnerable for the development of more serious clinical symptoms after suffering the infection, and to a greater extent cases with advanced HF3. In fact, HF is one of the most frequent complications in patients with COVID-194. Likewise, transplant patients who require immunosuppressants to avoid graft rejection, constitute a population especially susceptible to infection and to develop more serious processes. This situation has made the National Association of Cardiologists of Mexico (ANCAM) and the Mexican Society of Cardiology (SMC) together with their respective chapters, have prepared the following recommendations for medical personnel, who participate in the care of this special group of patients in the different clinical settings, who suffer or not, of COVID-19.

Association of CYP2C19*2 polymorphism with clopidogrel resistance among patients with high cardiovascular risk in Northeastern Mexico / Asociación del polimorfismo CYP2C19*2 con resistencia a clopidogrel en pacientes con alto riesgo cardiovascular en el noreste de México

abstract Objective: Oral antiplatelet drugs are a key to modern pharmacotherapy in cardiovascular atherothrombotic diseases. Clopidogrel (CLO) constitutes the main preventive treatment of atherothrombosis. However, a considerable inter-individual variation in CLO response has been documented, resulting in suboptimal therapy and an increased risk of recurrent adverse effects in some patients. The enzyme CYP2C19 has been reported to be the CYP isoform that activates CLO to its active metabolite. Several single nucleotide polymorphisms in the CYP2C19 gene have been identified as strong predictors of CLO-impaired pharmacological response. At least 16 variants have been associated with changes in CYP2C19 activity. Materials and Methods: The following research was composed of a total of 102 subjects with high cardiovascular risk in the northeast of Mexico, with a maintenance dose of 75 mg of CLO per day. The platelet reactivity was measured with VerifyNow P2Y12 assay, while the presence of CYP2C19*2 was identified by real-time polymerase chain reaction. Results: Patients were categorized by CYP2C19 metabolizer status based on *2 genotypes using the common consensus star allele nomenclature as normal metabolizer (G/G), intermediate metabolizer (G/A), and poor metabolizer (A/A), respectively. The phenotype frequency for CYP2C19*2 was 74.5% (G/G), 21.6% (G/A), and 3.9% (A/A). The subjects with the A allele presented ≥235 P2Y12 reaction unit levels, classifying them how poor metabolizer. The prevalence of reduced CLO effectiveness was associated with the presence of CYP2C19*2 polymorphism among Mexican patients. Conclusion: The presence of the CYP2C19*2 allele is related to resistance to the antiplatelet effect of CLO (p = 0.003).

Resumen Objetivo: Los antiplaquetarios orales son clave en la farmacoterapia moderna de las enfermedades aterotrombóticas cardiovasculares. Clopidogrel (CLO) constituye el principal tratamiento preventivo de aterotrombosis (AT). Sin embargo, se ha documentado una considerable variación interindividual en la respuesta a CLO, lo que da como resultado una terapia subóptima y mayor riesgo de efectos adversos en algunos pacientes. La enzima CYP2C19 es la isoforma CYP que activa CLO a su metabolito activo. Se han identificado varios polimorfismos de un solo nucleótido en el gen CYP2C19 como fuertes predictores de respuesta farmacológica alterada a CLO. Al menos 16 variantes se han asociado con cambios en la actividad de CYP2C19. Método: Se reclutaron un total de 102 sujetos con alto riesgo cardiovascular del noreste de México, con dosis de mantenimiento de 75 mg de CLO/día. La reactividad plaquetaria se midió con el ensayo Verify Now P2Y12, la presencia de CYP2C19*2 se identificó mediante polymerase chain reaction en tiempo real. Resultado: Los pacientes fueron clasificados por el estado metabolizador CYP2C19*2 utilizando nomenclatura consenso, como metabolizador normal (G/G), metabolizador intermedio (G/A) y metabolizador pobre (A/A), respectivamente. La frecuencia del fenotipo para CYP2C19*2 fue 74.5% (G/G), 21.6% (G/A) y 3.9% (A/A). Los sujetos con alelo A presentaron ≥235 niveles P2Y12 reaction unit, clasificándolos como metabolizadores deficientes. La prevalencia de eficacia reducida a CLO se asoció con la presencia del polimorfismo CYP2C19*2 en pacientes mexicanos. Conclusiones: La presencia del alelo CYP2C19*2 se relaciona con resistencia al efecto antiagregante plaquetario del CLO (p = 0.003).

Cardiovascular Risk and Metabolic Syndrome in Individuals with Mental Disorders

Patients with mental disorders are more susceptible to cardiovascular diseases and metabolic disorders compared to the general population. Objective: To evaluate cardiovascular risk and metabolic syndrome in individuals with mental disorders. Materials and methods: A cross-sectional study, conducted at the Psychosocial Care Centers. Socioeconomic, clinical, biochemical and anthropometric data were collected using a standard form. Cardiovascular risk was assessed by the Framingham risk score. Metabolic syndrome (MS) was determined by the World Health- Organization (WHO), the National Cholesterol Education Program (NCEP) and the International Diabetes Federation (IDF) criteria. Data were analyzed by descriptive statistics, and associations were evaluated by the chi-square test and Fisher's exact test, as well as Odds Ratio. The significance level adopted for all statistical tests was 5%. Results: The chance of individuals diagnosed with MS be at intermediate-to-high cardiovascular risk was greater (12.22, 8.01 and 6.23 times higher according to WHO, NCEP and IDF criteria, respectively) than those without MS. Conclusion: A high percentage of patients with mental disorders were at intermediate / high cardiovascular risk, and this was significantly associated with MS

Cardiovascular Risk in Psoriasis Patients: Clinical, Functional and Morphological Parameters / Risco Cardiovascular em Pacientes Psoriásicos: Avaliação de Parâmetros Clínicos, Funcionais e Morfológicos

Abstract Background: Psoriasis correlates with metabolic disorders, early atheromatosis and increased cardiovascular risk. Objectives: To assess markers of cardiovascular disease in psoriatic patients. Methods: Cross-sectional, observational study involving 11 psoriatic participants and 33 controls. Anthropometric, biochemical, hemodynamic and imaging parameters were evaluated. Arterial stiffness was assessed by oscillometric measurement of the brachial artery. Intima-media thickness (IMT) and left ventricular diastolic function were assessed by Doppler echography and echocardiography. Between-group comparisons of numerical variables were performed by the Student's t-test or Wilcoxon Mann-Whitney test for independent samples. Significance level was set at 5%. Results: Psoriatic patients showed increased pulse wave velocity (PWV) (9.1 ± 1.8 vs 8.0 ± 2 m/s, p = 0.033), IMT of the left common carotid artery (p = 0.018) and a higher percentage of patients above the 75th percentile according to the ELSA table when compared with controls (54.5 vs 18.2%, p = 0.045). Psoriatic patients also showed an increase in peripheral/central systolic blood pressure (137.1 ± 13.2 vs 122.3 ± 11.6 mmHg, p = 0.004)/(127 ± 13 vs 112.5 ± 10.4 mmHg, p = 0.005), peripheral/central diastolic blood pressure (89.9 ± 8.9 vs 82.2 ± 8, p = 0.022)/(91 ± 9.3 vs 82.2 ± 8.3, p = 0.014), total cholesterol (252 ± 43.5 vs 198 ± 39.8 mg/dL, p < 0.001), LDL cholesterol (167 ± 24 vs 118 ± 40.8 mg/dL, p < 0.001) and C-reactive protein (7.6 ± 35.4 vs 1 ± 1.2 mg/L p < 0.001) compared with controls. Conclusion: Psoriasis patients show increased PWV, IMT, peripheral and central blood pressures, and serum cholesterol and C-reactive protein levels, denoting a higher cardiovascular risk.

Resumo Fundamento: A psoríase correlaciona-se a distúrbios metabólicos, ateromatose precoce e aumento do risco cardiovascular. Objetivos: Avaliar marcadores de doença cardiovascular na população psoriásica. Métodos: Estudo observacional transversal, envolvendo 11 participantes psoriásicos e 33 controles. Foram avaliados parâmetros antropométricos, laboratoriais, hemodinâmicos e de imagem. A rigidez arterial foi avaliada por oscilometria da artéria braquial. A espessura médio-intimal (EMI) e a função diastólica do ventrículo esquerdo foram avaliadas por meio da ecografia e ecocardiografia Doppler. As comparações de variáveis numéricas entre grupos foram realizadas por teste t-Student e Wilcoxon Mann-Whitney para amostras independentes, adotando-se o nível de significância de 5%. Resultados: Os pacientes psoriásicos apresentaram aumento de VOP (9,1 ± 1,8 e 8 ± 2 m/s, p = 0,033), EMI da artéria carótida comum esquerda (p = 0,018) e maior proporção de percentil > 75 pela tabela ELSA (54,5 e 18,2%, p = 0,045) e) quando comparados aos controles. Pacientes psoriásicos também mostraram aumento nos seguintes parâmetros em relação ao grupo controle, respectivamente: pressão arterial sistólica periférica/central (137,1 ± 13,2 e 122,3 ± 11,6 mmHg, p = 0,004)/(127 ± 13 e 112,5 ± 10,4 mmHg, p = 0,005), pressão arterial diastólica periférica/central (89,9 ± 8,9 e 82,2 ± 8 mmHg, p = 0,022) / (91 ± 9,3 e 82,2 ± 8,3 mmHg, p = 0,014), colesterol total (252 ± 43,5 e 198 ± 39,8 mg/dL, p < 0,001), colesterol LDL (167 ± 24 e 118 ± 40,8 mg/dL, p < 0,001) e proteína C reativa (7,6 ± 35,4 e 1 ± 1,2 mg/L, p<0,001). Conclusão: Pacientes psoriásicos apresentam elevações de VOP e EMI, além de maiores pressões arteriais periféricas e centrais, níveis séricos de colesterol e de proteína C reativa, denotando maior risco cardiovascular.

Arterial stiffness in hyperthyroid patients is deteriorated due to thyroid hormones

ABSTRACT Objective The aim of this study is to evaluate and compare arterial stiffness, which is an independent risk indicator for cardiovascular diseases (CVDs), between patients with overt hyperthyroidism, subclinical hyperthyroidism, euthyroidism by antithyroid therapy and healthy volunteers with pulse wave analysis (PWA). Subjects and methods A total of 102 volunteers were included in the study (30 in the overt hyperthyroid group, 28 in the subclinical hyperthyroid group and 14 with euthyroidism by antithyroid therapy and 30 healthy). The arterial stiffness measurements of the participants in the study were performed with the Mobil-O-Graph PWA device (I.E.M. GmBH, Stolberg, Germany), which makes cuff based oscillometric measurement from the brachial artery. Results Systolic blood pressure, pulse rate, central systolic blood pressure, cardiac output, heart rate-corrected augmentation index (Aix@75) and pulse wave velocity (PWV) measurements were significantly higher in the hyperthyroid group than in the control group. The heart rate and PWV in the subclinical hyperthyroid group were significantly higher than the control group. In the euthyroid group, systolic blood pressure, central systolic blood pressure, cardiac output, cardiac index and PWV were found significantly higher than the control group. There was also a negative correlation between Aix@75 and thyroid-stimulating hormone (TSH), and a positive correlation between Aix@75 and free thyroid hormones. Conclusion In our study, we observed that the arterial stiffness was adversely affected by an overt or subclinical increase in thyroid hormones and this correlated with thyroid hormone levels. We recommend that PWV measurement, which is a simple method for detecting CVD risk, can be used in these patients.

Cardiometabolic risk factors associated with active commuting to school / Fatores de risco cardiometabólicos associados ao deslocamento ativo à escola

ABSTRACT Objective: To verify if there is an association between cardiometabolic risk factors and active daily commuting to school among children and adolescents. Methods: A total of 1,743 schoolchildren aged 7 to 17 years old were evaluated in the city of Santa Cruz do Sul (RS). The way of commuting to school was investigated with a questionnaire, and the cardiometabolic risk factors analyzed were body mass index (BMI), waist circumference (WC), systolic (SBP) and diastolic (DBP) blood pressure, blood glucose, triglycerides, total cholesterol (TC) and fractions, LDL and HDL. Results: The prevalence of active commuting among schoolchildren was 48.0% (95%CI 45.7-50.4), and it was associated, in the crude analysis, with blood glucose and LDL cholesterol levels. Passive schoolchildren had a 1.1 higher prevalence ratio of high glucose and LDL cholesterol levels. However, when sociodemographic variables were included in the model, these associations were not maintained. Conclusions: The prevalence of active commuting in the sample studied is low and it was shown to have a crude association with glucose and LDL cholesterol levels in students. However, sociodemographic factors seem to influence these associations.

RESUMO Objetivo: Verificar se existe associação entre fatores de risco cardiometabólicos e deslocamento ativo à escola em crianças e adolescentes. Métodos: Foram avaliados 1.743 escolares, de sete a 17 anos, do município de Santa Cruz do Sul (RS). A forma de deslocamento até a escola foi investigada por meio de questionário e os fatores de risco cardiometabólicos analisados foram: o índice de massa corpórea (IMC), a circunferência da cintura (CC), a pressão arterial sistólica (PAS) e a diastólica (PAD), glicose, triglicerídeos, colesterol total (CT), LDL e HDL. Resultados: A prevalência de deslocamento ativo entre os escolares foi de 48,0% (IC95% 45,7-50,4) e associou-se, na análise bruta, com os níveis de glicose e colesterol LDL. Escolares que se deslocavam de forma passiva apresentaram uma razão de prevalência (RP) 1,1 vez maior de glicose e colesterol LDL elevados. No entanto, ao serem incluídas variáveis sociodemográficas no modelo, essas associações não se mantiveram. Conclusões: Conclui-se que a prevalência de deslocamento ativo na amostra estudada é baixa e que o deslocamento ativo à escola apresentou associação bruta com os níveis sanguíneos de glicose e de colesterol LDL dos escolares, sendo que se deslocar de forma ativa parece auxiliar na redução desses níveis. Porém, fatores sociodemográficos parecem exercer influência sobre estas associações.

Asociación entre deterioro del flujo espiratorio máximo y prevalencia de enfermedades cardiovasculares y metabólicas en población adulta chilena: hallazgos preliminares de la Cohorte del Maule (MAUCO) / Peak expiratory flow and prevalence of cardiovascular and metabolic diseases in a Chilean adult population: preliminary findings from the Maule Cohort (MAUCO)

Introducción: La enfermedad respiratoria crónica determina alta morbimortalidad y frecuencia de comorbilidades cardiometabólicas. Evaluamos la asociación entre flujo espiratorio máximo (FEM) y algunas condiciones cardiometabólicas en adultos de una zona semirural, en la medición basal de la cohorte MAUCO (MAUle COhort). Material y Método: Estudio transversal (3.465 adultos, 40-74 años). Se midió el flujo espiratorio máximo (FEM) (mini-Wright, estándar ATS) utilizándose valores de Gregg y Nunn (FEM deteriorado ≤ 80% del teórico). Se obtuvo autorreporte/mediciones de hipertensión arterial (HTA), enfermedad cerebrovascular (ECV), infarto al miocardio (IAM), diabetes mellitus 2 (DM2), presión arterial, glicemia, colesterol, peso y talla. Actividad física y tabaquismo se evaluaron por encuesta, previa aprobación Ética. Se calcularon medidas de asociación, prevalencia y Odds Ratio (OR). Resultados: Muestra de 63,9% de mujeres edad media 55 (± 9) años, escolaridad media 9 (± 4) años. 84,7% tuvo exceso de peso, 81,5% inactividad física 29,4% fumadores actuales. Prevalencia de FEM bajo: 50,6% (IC 95% 48,9-52,3). El autorreporte fue: ACV 2,2% IAM 3,3, sospecha de hipertensión 24% y DM2 2,7%. Los OR crudos fueron significativos en mujeres que autorreportaron HTA, ECV, IAM y autorreporte/sospecha de DM2, y en hombres con autorreporte de ECV, sospecha de DM2 y autorreporte/sospecha de HTA. La asociación se mantuvo post-ajuste en mujeres para autorreporte de IAM y deterioro moderado (OR = 2,49) y severo del FEM (OR = 2,60) y en hombres para sospecha de DM2 y deterioro leve (OR = 5,24) y severo del FEM (OR = 6,19). Conclusiones: FEM resultó significativamente asociado con las enfermedades cardiometabólicas seleccionadas, con efecto sexo- específico para IAM (mujeres) y sospecha de DM2 (hombres). Se constata alta prevalencia de FEM alterado, y de enfermedades cardiometabólicas crónicas en la población estudiada.

Introduction: Chronic respiratory diseases determine high morbimortality and cardiometabolic comorbidities. We evaluated the association between peak expiratory flow (PEF) and cardiometabolic conditions in adults in a semi-rural area, in the baseline of MAUCO cohort (MAUle COhort). Material and Method: Cross-sectional study (3,465 adults, 40-74 years). Peak expiratory flow (PEF) (mini-Wright, ATS standard) was measured (Gregg & Nunn; impaired PEF ≤ 80% predicted). Self-reported/measured hypertension (HT), cerebrovascular disease (CVD), myocardial infarction (AMI), diabetes mellitus 2 (DM2), blood pressure, glycemia, cholesterol, weight and height were obtained. Physical activity and smoking were surveyed, after Ethical approval. Association's measures, prevalence and Odds Ratio (OR) were calculated. Results: Sample of 63.9% of women, mean age 55 (± 9) years, schooling 9 (± 4) years. 84.7% had overweight, 81.5%physical inactivity 29.4% smokers. Low PEF: 50.6% (48.9-52.3). Self-reported was: CVD 2.2% AMI 3.3%, suspicion of hypertension 24% and DM2 2.7%. Crude OR`s were significant for women by self-reported hypertension, stroke, AMI and self-reported/suspicion DM2; in men for self-reported CVD, suspected DM2 and self-reported/suspected hypertension. The association remained post-adjusted in women self-reported AMI -moderate deterioration (OR = 2.49) and severe PEF (OR = 2.60) and in men suspected DM2 and mild (OR = 5.24) and severe deteriorated PEF (OR = 6.19). Conclusions: PEF was significantly associated with cardiometabolic diseases; sex- specific findings for AMI (women) and suspicion of DM2 (men). High prevalence of altered PEF and chronic cardiometabolic diseases were detected among the studied population.

Presence of age- and sex-related differences in heart rate variability despite the maintenance of a suitable level of accelerometer-based physical activity

There is currently a lack of information adjacent on the influence of sex and age in heart rate variability (HRV), adjusted according to accelerometer-based physical activity (PADL). We hypothesized that the effect of sex and age on the HRV should be reduced or absent in individuals with a suitable PADL level. We aim to evaluate the influence of sex and age on HRV, adjusted for the confounding effects of the PADL level. A total of 485 age-stratified subjects (18-39, 40-59, and ≥60 years) underwent HRV analyses at rest and 7-day assessments of accelerometer-based PADL. Multivariate analyses of covariance were done using log-transformed HRV indices as outcomes, age and sex as fixed factors, and PADL, cardiovascular risk, fat body mass, and heart rate (HR) at rest as covariates. Despite the adjustment for directly measured PADL, women had better indices of vagal tone, whereas men had higher sympathetic influence. Also, compared to middle-aged and older adults, younger individuals (ages 18-39 years) presented better HRV. Multiple regression analyses confirmed that age and sex were the main predictors of HRV indices, even after adjusting for PADL directly assessed by triaxial accelerometer and HR. We also observed that the correlation between some HRV indexes and the different indexes of physical activity directly evaluated was significant, but not very consistent. Thus, HRV indices are influenced by age and sex, regardless of accelerometer-based physical activity. Interventions with physical activity and exercise aimed at improving the autonomic modulation of asymptomatic adults should take such differences into account.

Non Electrocardiographic alterations in exercise testing in asymptomatic women. Associations with cardiovascular risk factors

OBJECTIVES: To estimate the prevalence of exercise testing alterations in middle-aged women without symptoms of heart disease and to verify the associations of functional capacity and heart rate behavior during and after exercise with cardiovascular risk factors. METHODS: A cross-sectional study was conducted with 509 asymptomatic women aged between 46 and 65 years who underwent clinical evaluations and exercise testing (Bruce protocol). The heart rate behavior was evaluated by the maximal predicted heart rate achieved, chronotropic index and recovery heart rate. RESULTS: The mean age was 56.4±4.8 years, and 13.4% of the patients had a Framingham risk score above 10%. In the exercise treadmill testing, 58.0% presented one or more of the following alterations (listed in order of ascending prevalence): symptoms (angina, dyspnea, and dizziness), ST-segment depression, arrhythmia, reduction in recovery heart rate of ≤12 bpm at 1 minute, altered maximal predicted heart rate achieved, abnormal blood pressure, functional capacity deficiency, and altered chronotropic index. In the multivariate analysis, the following associations (odds ratio) were observed for these alterations: chronotropic index was associated with obesity (2.08) and smoking (4.47); maximal predicted heart rate achieved was associated with smoking (6.45); reduction in the recovery heart rate at 1 minute was associated with age (1.09) and obesity (2.78); functional capacity was associated with age (0.92), an overweight status (2.29) and obesity (6.51). CONCLUSIONS: More than half of middle-aged women without cardiovascular symptoms present alterations in one or more exercise testing parameters. Alterations in the functional capacity or heart rate behavior, as verified by exercise testing, are associated with age, smoking, an overweight status and obesity.

Tendências das internações por condições cardiovasculares sensíveis à atenção primária à saúde no município de Senador Canedo, Goiás, 2001-2016 / Tendencias de las internaciones por condiciones cardiovasculares sensibles a la atención primaria de salud en el municipio de Senador Canedo, Goiás, Brasil, 2001-2016 / Trends of hospitalizations for ambulatory care-sensitive cardiovascular conditions in the municipality of Senador Canedo, Goiás, Brazil, 2001-2016

Consideraciones en torno a las Guías USA 2017 de hipertensión arterial / A word of caution about the 2017 hypertension management guidelines

The 2017 Guidelines on hypertension of the American College of Cardiology and American Heart Association, which proposed values of 130/80 mmHg as the cutoff points for the onset of hypertension, aroused great interest. This recommendation is based in the SPRINT study (The Systolic Pressure Intervention Trial), which included hypertensive patients over 50 years of age, non-diabetic, without a history of stroke and with a low representation of subjects with a history of coronary artery disease (16%). A group with intensive anti-hypertensive therapy (pressure achieved 121.5 mmHg) achieved a significantly lower cardiovascular risk as compared with a group with standard therapy (pressure achieved 134.6 mmHg). The Guide proposes immediate pharmacological therapy in diabetic hypertensive patients, in those with stage 3 chronic kidney disease or with persistent albuminuria, and in patients with atherosclerotic disease. The Guideline does not include the management of isolated systolic hypertension of the elderly and did not consider studies that show an increased risk when pressure is reduced below 130/80 mmHg in patients with coronary disease, peripheral vascular disease, diabetes mellitus or chronic renal failure. The new classification of hypertension would increase the number of hypertensive patients in our country by more than one million, would increase the risk associated with diastolic pressure reductions in older adults and ignores the evidence indicating a risk associated with reductions below 130/80 mmHg in patients with diabetes, with chronic renal failure or with atherosclerotic disease. Therefore, it is advisable to maintain a threshold of 140/90 mmHg and perform a careful and gradual management of blood pressure in the latter group of hypertensive patients.

Análise espacial e tendências de mortalidade associada a doenças hipertensivas nos Estados e Regiões do Brasil entre 2010 e 2014 / Spatial analysis and mortality trends associated with hipertensive diseases in the States and Regions fo Brazil from 2010 to 2014

Fundamentos: A hipertensão arterial sistêmica (HAS) representa o agravo de maior relevância, sendo um dos principais fatores de risco para doenças cardiovasculares. Objetivo: Analisar tendências da taxa de mortalidade associada a doenças hipertensivas no Brasil, de 2010 a 2014, tanto para os estados quanto para as regiões. Métodos: Estudo epidemiológico a partir de dados agregados, obtidos em estratos populacionais. Dados cartográficos em "shapefile" do território brasileiro foram fornecidos pelo IBGE. Registros de mortalidade associada à hipertensão arterial obtidos no DATASUS, mediante notificações filtradas por categoria I.10 do Código Internacional das Doenças (CID-10). Adotou-se como critério de significância estatística o valor de p bicaudal < 0,05. Resultado: O aumento da idade se associou de maneira progressiva à elevação da média de óbitos relacionada a doenças hipertensivas entre os anos de 2010 e 2014. Nas faixas etárias entre 50-59 anos, 60-69 anos, 70-79 anos e 80 ou mais anos, a média e desvio da taxa de mortalidade padrão foram, respectivamente: 15,11% (35,35); 24,14% (55,34); 35,07% (81,03) e 57,87% (139,08). A taxa global de mortalidade nas regiões brasileiras, por 10.000 habitantes, variou entre as regiões: norte (1,25); nordeste (2,69); centro-oeste (2,06); sudeste (2,48) e sul (2,04). Conclusão: A taxa de mortalidade associada a doenças hipertensivas foi superior nos estados do sudeste e nordeste do Brasil, e permaneceu estável entre 2010 e 2014. Incremento de idade e cor parda foram preditores de maior mortalidade

Background: Systemic Arterial Hypertension (SAH) represents the most relevant worsening factor and one of the major risk factors for cardiovascular diseases. Objectives: To analyze trends in the mortality rate associated with hypertensive diseases in Brazil from 2010 to 2014, for states as well as regions. Methods: An epidemiological study was performed from aggregate data obtained in populational strata. Cartographic data of the Brazilian territory in "shapefile" were provided by IBGE. Records of mortality associated with arterial hypertension were obtained in DATASUS, through notifications filtered by category I.10 of the International Classification of Diseases (ICD-10). The criterion of statistical significance was a two-tailed p-value < 0.05. Results: The increase in age was progressively associated with an increase in the mean number of deaths related to hypertensive diseases between the years 2010 and 2014. In the age groups between 50-59 years, 60-69 years, 70-79 years and 80 or more years, the mean and standard deviation for the mortality rate were, respectively: 15.11% (35.35); 24.14% (55.34); 35.07% (81.03) and 57.87% (139.08). The overall mortality rate per 10,000 inhabitants varied between the regions: north (1.25); northeast (2.69); center-west (2.06); southeast (2.48) and south (2.04). Conclusion: The mortality rate associated with hypertensive diseases was higher in the southeastern and northeastern states of Brazil, and remained stable between 2010 and 2014. Increased age and brown color were predictors of higher mortality

Síndrome metabólica e resistência insulínica pelo Homa-IR no climatério / Metabolic syndrome and insulin resistance by HOMA-IR in menopause

Fundamento: Síndrome metabólica é um importante fator de risco cardiovascular, e sua prevalência aumenta após a menopausa. Ainda é incerto, porém, se a menopausa é fator de risco independente para a síndrome metabólica. Uma das bases fisiopatológicas para síndrome metabólica é a resistência insulínica, que pode ser calculada pelo método Homeostatic Model Assessment-Insulin Resitance (HOMA-IR), sendo pouco conhecida a relação entre resistência insulínica e menopausa. Objetivos: Avaliar a relação entre síndrome metabólica e resistência insulínica em mulheres climatéricas. Métodos: Estudo descritivo, que avaliou 150 mulheres, com idades entre 40 e 65 anos, atendidas em um ambulatório de ginecologia em um hospital terciário público, entre maio e dezembro de 2013. A amostra foi dividida em dois grupos, sendo o Grupo I com pacientes na pré-menopausa e o II com pacientes na pós-menopausa. Foi avaliada a presença de síndrome metabólica, bem como de seus componentes, além da ocorrência de resistência insulínica nos dois grupos. A associação do estado menopausal e as variáveis estudadas foi realizada com os testes Mann-Whitney, qui quadrado e exato de Fisher. O nível de significância foi de 5%. A análise estatística foi feita por meio do STATA 12.0. Resultados: A síndrome metabólica foi mais prevalente nas mulheres pós-menopausa, bem como todos seus componentes tiveram maior frequência também nesse grupo. As mulheres pós-menopausa também apresentaram maior prevalência de resistência insulínica, mas não foi observada relação estatística entre os achados. Conclusão: O estado menopausal não se associou significativamente com síndrome metabólica e resistência insulínica. A resistência insulínica foi considerada fator de risco independente para o desenvolvimento de síndrome metabólica apenas no grupo pós-menopausa

Background: Metabolic syndrome is an important cardiovascular risk factor, and its prevalence increases after menopause. However, it is still uncertain whether menopause is an independent risk factor for metabolic syndrome. One of the pathophysiological basis for metabolic syndrome is insulin resistance, which can be calculated by the Homeostatic Model Assessment-Insulin Resistance (HOMA-IR) method, and the association between insulin resistance and menopause is little known. Objective: To evaluate the association between metabolic syndrome and insulin resistance in menopausal women. Method: Descriptive study, which evaluated 150 women, aged 40 to 65, treated at a Gynecology Outpatient Clinic of a tertiary public hospital, from May to December of 2013. The sample was divided into two groups: Group I, comprising women in the premenopausal period and Group II, comprising women in the post-menopausal period. The presence of metabolic syndrome and its components were evaluated, as well as occurrence of insulin resistance in both groups. The association of menopausal status and the assessed variables was assessed using the Mann-Whitney, Chi-square and Fisher's exact tests. The significance level was set at 5%. The statistical analysis was performed using STATA 12.0. Results: Metabolic syndrome and its components were more prevalent in postmenopausal women. Postmenopausal women also had a higher prevalence of insulin resistance, but no statistical association was observed between the findings. Conclusion: The menopausal status was not significantly associated with metabolic syndrome and insulin resistance. Insulin resistance was considered an independent risk factor for the development of metabolic syndrome only in the postmenopausal group

Oral health status, health behaviour and treatment needs of patients undergoing cardiovascular surgery

Abstract Objective: The aim of the present study was to assess the oral health status and treatment needs of cardiovascular surgery patients. Second, the awareness of cardiovascular surgery patients regarding the association between oral health and heart disease was considered. Methods: Assessment of oral health status, oral hygiene practices and treatment needs of 106 hospitalized patients in preparation for cardiovascular surgery. Patients were interviewed using a structured questionnaire designed for this study and oral examination was carried out by a dentist. Results: The oral hygiene practices of the study cohort were not up to the standard. Patients' awareness of infective endocarditis was poor. Approximately 68% patients experienced dental caries as decayed teeth or missing teeth due to caries and filled teeth. The mean plaque index in the study group was 1.25. In this study cohort, the mean probing depth of periodontal pockets was 5.7±1.3, whereas the mean number of teeth with periodontal pockets > 6 mm was 0.5±0.9. A total of 84 (74.2%) of the patients required dental treatment. Conclusion: The principal finding in this study was that patients with heart disease had poor oral health. This study also highlights the importance of better interaction among all healthcare professionals to integrate oral health as part of comprehensive inpatient healthcare.

The effect of hemodialysis on the body composition and cardiovascular disease markers in recently diagnosed end stage renal disease patients

SUMMARY AIM: Uremic toxins and excess fluid contributes to increased cardiovascular (CV) risk. We aimed to determine the body fluid status in patients who are just starting hemodialysis (HD) and to determine the effects of excess fluid removed by HD on the CV system. METHODS: A total of 52 patients with chronic kidney disease (CKD) who had just started HD were included. Before the HD, the left atrial diameter was measured, the volumes were calculated, the pulse wave velocity (PWV) and the augmentation index (AIx) were measured, the bioimpedance analysis (BIA) was performed, the blood was taken for brain natriuretic peptide (BNP). When patients reached their dry weight with HD, the same measurements were repeated. RESULTS: Measurements were made to determine the volume status, and all parameters except the fat tissue index decreased significantly after HD. With the removal of fluid by HD, there was an average weight reduction of 4.38 kilograms. Positive correlations between PWV and age and cardiothoracic ratio (CTR) before HD were determined. Negative correlations were found between PWV and lean tissue mass (LTM) and intracellular water (ICW) before HD. At the end of the last HD, PWV was positively correlated with age, CTR, central pulse pressure Correlation between pulse wave velocity and LTI was negative CONCLUSIONS: HD significantly improves PWV in patients reaching dry weight. Reduction of fluid excess by ultrafiltration in HD patients may reduce CV mortality by reducing arterial stiffness.

RESUMO INTRODUÇÃO: Em pacientes com doença renal crônica (DRC), toxinas urêmicas e hipervolemia contribuem para aumentar o risco cardiovascular. Nosso objetivo foi determinar o estado de hidratação em pacientes com DRC iniciando hemodiálise (HD) e avaliar os efeitos da correção da hipervolemia sobre o sistema cardiovascular. MÉTODOS: Foram incluídos 52 pacientes que haviam acabado de iniciar HD. Antes do início da sessão, foram determinados o diâmetro e o volume atrial esquerdo, a velocidade de onda de pulso (VOP) e o índice de amplificação sistólica ("augmentation index", AI). Além disso, realizamos análise da composição corporal por bioimpedância elétrica (BIA) e mensuramos os níveis plasmáticos de peptídeo natriurético tipo B. Os mesmos procedimentos foram repetidos após os pacientes alcançarem o "peso seco". RESULTADOS: O peso corporal dos pacientes foi reduzido, em média, em 4,38 kg. Na BIA, todos os parâmetros, exceto o índice de gordura corporal, foram significativamente reduzidos após a hemodiálise. Antes da HD, a VOP se correlacionou positivamente com idade e razão cardiotorácica (RCT), e negativamente com a massa magra e a água intracelular. Ao final da hemodiálise, a VOP se correlacionou positivamente com idade, RCTe pressão de pulso central, correlacionando-se negativamente com a Lean Tissue Index (LTI). CONCLUSÃO: A hemodiálise melhora a VOP por meio da redução da volemia. O controle da hipervolemia via ultrafiltração pode reduzir a mortalidade cardiovascular por meio da redução da rigidez arterial.

Leisure-Time Physical Activity, but not Commuting Physical Activity, is Associated with Cardiovascular Risk among ELSA-Brasil Participants / Atividade Física no Tempo Livre, porém não Atividade Física no Deslocamento, está Associada com Risco Cardiovascular em Participantes do ELSA-Brasil

Abstract Background: Despite reports in the literature that both leisure-time physical activity (LTPA) and commuting physical activity (CPA) can promote health benefits, the literature lacks studies comparing the associations of these domains of physical activity with cardiovascular risk scores. Objective: To investigate the association between LTPA and CPA with different cardiovascular risk scores in the cohort of the Longitudinal Study of Adult Health ELSA-Brasil. Methods: Cross-sectional study with data from 13,721 participants of both genders, aged 35-74 years, free of cardiovascular disease, from ELSA Brazil. Physical activity was measured using the International Physical Activity Questionnaire (IPAQ). Five cardiovascular risk scores were used: Framingham score - coronary heart disease (cholesterol); Framingham score - coronary heart disease (LDL-C); Framingham score - cardiovascular disease (cholesterol); Framingham score - cardiovascular disease (body mass index, BMI); and pooled cohort equations for atherosclerotic cardiovascular disease (ASCVD). Associations adjusted for confounding variables between physical activity and different cardiovascular risk scores were analyzed by logistic regression. Confidence interval of 95% (95%CI) was considered. Results: LTPA is inversely associated with almost all cardiovascular risk scores analyzed, while CPA shows no statistically significant association with any of them. Dose-response effect in association between LTPA and cardiovascular risk scores was also found, especially in men. Conclusions: LTPA was shown to be associated with the cardiovascular risk scores analyzed, but CPA not. The amount of physical activity (duration and intensity) was more significantly associated, especially in men, with cardiovascular risk scores in ELSA-Brasil.

Resumo Fundamento: Apesar dos relatos na literatura de que tanto a atividade física no tempo livre (AFTL) quanto a atividade física no deslocamento (AFDESL) promovem benefícios à saúde, estudos comparando a associação desses domínios da atividade física com escores de risco cardiovascular são escassos. Objetivo: Verificar a associação entre AFTL e AFDESL com escores de risco cardiovascular na coorte Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil). Métodos: Estudo transversal com dados da linha de base de 13.721 participantes de ambos os sexos, com idades entre 35 e 74 anos, livres de doenças cardiovasculares, do ELSA-Brasil. A atividade física foi mensurada por meio do International Physical Activity Questionnary (IPAQ). Foram utilizados cinco escores de risco cardiovascular: escore de Framingham - doença coronariana (colesterol); escore de Framingham - doença coronariana (lipoproteína de baixa densidade - LDL-C); escore de Framingham - doença cardiovascular (colesterol); escore de Framingham - doença cardiovascular (índice de massa corpórea - IMC); e equações de coorte agrupadas para doença cardiovascular aterosclerótica. As associações ajustadas por variáveis de confundimento foram analisadas por meio de regressão logística. Utilizou-se intervalo de confiança de 95% (IC95%). Resultados: Com quase todos os escores de risco cardiovascular analisados, a AFTL apresenta-se inversamente associada, enquanto a AFDESL não demonstra associação estatisticamente significante com nenhum deles. Observou-se, ainda, a existência de efeito dose-resposta na associação entre AFTL e escores de risco cardiovascular principalmente em homens. Conclusões: A AFTL, porém não a AFDESL, apresenta associação com os escores de risco cardiovascular analisados. A maior quantidade de atividade física (duração e intensidade) está associada de forma mais significativa, principalmente em homens, aos escores de risco cardiovascular em participantes da coorte ELSA-Brasil.

Association between premature ventricular complexes during exercise, long-term occurrence of life-threatening arrhythmia and mortality / Asociación entre ectopia ventricular en ejercicio, la ocurrencia de arritmias potencialmente mortales y mortalidad a largo plazo

Abstract Objective: Exercise-induced premature ventricular complexes (EiPVCs) are often considered as benign arrhythmias, although they are associated with a high risk of all-cause death in the general healthy population. However, an intermediate pathophysiological process remains unclear, particularly in patients with known cardiovascular disease. The aim of this study was to find an association between EiPVCs, the occurrence of life-threatening ventricular arrhythmias (LACO), and all-cause mortality in patients with cardiovascular disease. Methods: This was an observational study of a cohort of patients with coronary artery disease (CAD) or idiopathic cardiomyopathy (ICM). Stress testing was performed as a part of the routine cardiovascular evaluation. The occurrence of EiPVCs was evaluated during exercise testing (ET). At follow-up, long-term occurrence of LACO was evaluated. A bivariate and multivariate analysis was performed. Results: Out of the total of 1442 patients analysed, 700 (49%) had EiPVCs. During 14 years of following-up after ET, 106 LACO outcomes were observed. Long-term all-cause mortality was 4% (n = 61). A bivariate analysis showed that patients with EiPVCs had an increased risk for LACO (RR = 2.81, 95% CI; 1.9---4.3, P < .001), and for mortality (RR = 2.1, CI95% 1.2---3.4, P < .01). Occurrence of LACO was also associated with a higher mortality risk (RR = 5.7, 95% CI; 3.4---9.4, P < .001). After a post hoc analysis, LACO remained as a highly predictive variable for mortality. Conclusion: Patients with EiPVCs have a high risk of LACO and all-cause mortality. The presence of LACO could be an intermediate stage between EiPVCs and mortality in subjects with cardiovascular disease.

Resumen Objetivo: La extrasistolia ventricular inducida por ejercicio (EVIE) suele considerarse una arritmia benigna, sin embargo, ha sido asociada a mayor mortalidad en población general. Hasta hoy no se ha encontrado el proceso fisiopatológico involucrado, particularmente en pacientes con enfermedad cardiovascular. El objetivo del estudio fue establecer una asociación entre EVIE con la ocurrencia de arritmias ventriculares potencialmente malignas (APM) y letalidad a largo plazo, en sujetos con enfermedad cardiovascular. Método: Estudiamos una cohorte de pacientes con enfermedad coronaria o miocardiopatía dilatada, que realizaron una prueba de ejercicio al inicio del estudio. Inicialmente evaluamos la ocurrencia de EVIE, APM y letalidad a largo plazo y posteriormente se realizó un estudio bivariable y multivariable. Resultados: Se incluyeron 1,442 pacientes de los cuales 700 presentaron EVIE (49%). Durante 14 an˜os de seguimiento, 106 sujetos presentaron APM y la mortalidad total fue de 61 casos (4%). El estudio bivariable mostró que aquellos pacientes con EVIE tuvieron un riesgo de presentar APM de 2.81 (IC95% de 1.9 a 4.3, p < 0.001) y de mortalidad de 2.1 (IC95% de 1.2 a 3.4, p < 0.01). Los individuos con APM tuvieron mayor riesgo de mortalidad (RR= 5.7, IC95% de 3.4 a 9.4, p < 0.001). Después de un análisis multivariable, la APM continuó siendo una variable altamente predictiva de mortalidad. Conclusión: Los pacientes con EVIE tienen un riesgo elevado de presentar APM y de mortalidad a largo plazo. Los resultados sugieren que las APM podrían representar un estado intermedio entre la presencia de EVIE y la mortalidad en pacientes con enfermedad cardiovascular.
