Factores de riesgo cardiovascular y condiciones socioeconómicas y sociodemográficas en México, 2000 - 2018 / Cardiovascular risk factors and socioeconomic and sociodemographic conditions in Mexico, 2000 ­ 2018

Resumen Introducción: En países de ingresos altos, el nivel socioeconómico se relaciona con diferencias en la prevalencia e incidencia de los factores de riesgo cardiovascular. En países de ingresos medios como México, la evidencia es menor por lo que el objetivo del estudio fue estimar las tendencias en las prevalencias de seis de los principales factores modificables de riesgo cardiovascular; a saber, diabetes, hipertensión arterial, colesterol elevado, consumo de tabaco, consumo de alcohol y obesidad, según el nivel de condiciones socioeconómicas en el hogar y su asociación con determinados factores sociodemográficos entre personas adultas de 20 y más años en el periodo 2000-2018. Método: Los datos se obtuvieron de cuatro encuestas de salud de tipo transversal, representativas a nivel nacional. Con muestras individuales de cada encuesta, se estimaron las prevalencias de los factores de riesgo cardiovascular. Con un análisis por conglomerados se determinaron tres niveles de condiciones socioeconómicas. En cada muestra, con regresiones logísticas, se estimaron las prevalencias de cada factor de riesgo, según el nivel socioeconómico determinado por cada conglomerado ajustando por sexo, edad y escolaridad. Resultados: A diferencia de la diabetes, la hipertensión, el colesterol o la obesidad, el consumo de tabaco y de alcohol ha disminuido. La obesidad, la hipertensión arterial, el consumo de tabaco o de alcohol y el colesterol elevado mostraron diferencias entre los niveles alto y bajo de condiciones socioeconómicas en los cuatro puntos analizados, pero no la diabetes. Conclusión: Deben consolidarse programas y políticas enfocadas a la modificación, atención y tratamiento médico de los factores de riesgo cardiovascular.

Abstract Introduction: In high-income countries, socioeconomic status is related to differences in the prevalence and incidence of cardiovascular risk factors. In middle-income countries like Mexico, the evidence is less so the objective of the study was to estimate the trends in the prevalences of six of the main modifiable cardiovascular risk factors: diabetes, hypertension, high cholesterol, tobacco use, alcohol use, and obesity, according to the level of socioeconomic conditions at home among adults 20 years of age and over in the period 2000 - 2018. Method: The data were obtained from four nationally representative cross-sectional health surveys. With individual samples from each survey, the prevalences of cardiovascular risk factors were estimated. With a cluster analysis, three levels of socioeconomic conditions were determined. In each sample, with logistic regressions, the prevalences of each risk factor were estimated according to the socioeconomic level determined by each cluster, adjusting for sex, age, and education. Results: Unlike diabetes, hypertension, cholesterol or obesity, tobacco and alcohol consumption have decreased. Obesity, arterial hypertension, tobacco or alcohol consumption and high cholesterol showed differences between the high and low levels of socioeconomic conditions in the four points analyzed, but not diabetes. Conclusion: Programs and policies focused on the modification, care and medical treatment of cardiovascular risk factors should be consolidated.

Estudio de la deformación miocárdica longitudinal en pacientes con cardiopatía isquémica / Study of longitudinal myocardial deformation in patients with ischemic cardiopathy

Resumen Introducción: Las enfermedades cardiovasculares constituyen la primera causa de muerte en Cuba y la mayoría de los países desarrollados. La ecocardiografía con speckle tracking bidimensional (ST 2D) es una técnica reciente en la evaluación de la función cardíaca. Objetivos: Determinar la relación entre la deformación miocárdica medida por ST 2D y el estado de la circulación coronaria en pacientes con cardiopatía isquémica, en el CIMEQ, durante un año. Material y método: Se realizó un estudio analítico y transversal con 55 pacientes con indicación de coronariografía sometidos a ecocardiograma bidimensional y estudio de ST 2D con medición de la deformación longitudinal (DLG). Se crearon dos grupos: enfermedad coronaria significativa (ECS = 32) y no significativa (ECNS = 23). Se utilizó SSPS para análisis de los resultados. Resultados: La edad promedio fue mayor en la ECS (55.6 ± 9.3 vs. 61.8 ± 8.8; p = 0.014). Predominaron los hombres con ECS (47.3%), los hipertensos (ECS = 90.6% y ENCS = 65.2%; p = 0.02) y los fumadores (ECS = 59.4% y ENCS = 17.4%; p = 0.002). El diagnóstico más frecuente fue la angina crónica estable (87%). En la ECS predominó la enfermedad de tres vasos (75%). La DLG fue menor en la ECS [(-20.0 ± 3.2 vs. -22.1 ± 3.6; p = 0.035); AUC = 0.458]. No hubo diferencias en la DLG según el número de vasos significativamente afectados. Conclusiones: Los resultados encontrados no justifican el empleo del ST 2D para diferenciar la ECS.

Abstract Introduction: Cardiovascular diseases are the leading cause of death in Cuba and most of the developed countries. Two-dimensional speckle tracking echocardiography (2D ST) is a recent technique in the evaluation of cardiac function. Objectives: To determine the relationship between myocardial deformation measured by 2D ST and coronary circulation in patients with ischemic heart disease, in the CIMEQ, for 1 year. Material and method: An analytical, cross-sectional study was carried out with 55 patients with an indication for coronary angiography who underwent 2D echocardiography and 2D ST study with longitudinal strain measurement (LSM). Two groups significant coronary disease (SCD = 32) and not significant (NSCD = 23) were created. SSPS was used to analyze the results. Results: The average age was higher in SCD (55.6 ± 9.3 vs. 61.8 ± 8.8, p = 0.014). Men with SCD (47.3%), hypertensive (SCD = 90.6% and NSCD = 65.2%, p = 0.02) and smokers (SCD = 59.4% and NSCD = 17.4%, p = 0.002) predominated. The most frequent diagnosis was chronic stable angina (87%). Three-vessel disease (75%) prevailed in SCD. The LMS was lower in SCD ([−20.0 ± 3.2 vs. −22.1 ± 3.6, p = 0.035]; AUC = 0.458). There were no differences in LSM according to the number of significantly diseased vessels. Conclusions: The results found do not justify the use of 2D ST to discriminate SCD.

Análisis con perspectiva de género sobre percepción y prácticas en enfermedad coronaria en mujeres en el norte de México / A gender perspective analysis of perception and practices in coronary disease in women from northern México

Resumen: Objetivo: Analizar la percepción de riesgo coronario y prácticas de cuidados de un grupo de mujeres mexicanas, desde una perspectiva de género. Material y métodos: Estudio realizado de septiembre de 2013 a diciembre de 2014 en el estado de Sonora, México. Diseño mixto: encuesta a 140 mujeres. Análisis: contraste de proporciones; nueve entrevistas en profundidad a mujeres con enfermedad coronaria; ocho entrevistas semiestructuradas a médicos. Aplicación de técnicas de la teoría fundamentada. Resultados: Más de 50% desconoce su riesgo y cómo reducirlo. Mujeres informadas vulnerables con dolor de pecho buscan menos atención médica que las no vulnerables p=0.01 y son responsabilizadas por parte del personal médico sobre su enfermedad. Las mujeres consideran que están desinformadas sobre cómo reducir el riesgo de enfermedad coronaria; sin embargo, se culpabilizan por enfermar. Conclusiones: Las condiciones de vulnerabilidad de las mujeres modulan una baja percepción de riesgo coronario y mínimas prácticas de cuidados.

Abstract: Objective: To analyze the perception of coronary risk and health care practices in a group of Mexican women, from a gendered perspective. Materials and methods: Mixed methods: survey of 140 women; nine in-depth interviews to women with coronary disease; eight semi-structured interviews to physicians. Analysis: proportions contrast for quantitative data; and procedures of grounded theory for qualitative information. Results: More than 50% of women don't know their coronary risk and how to reduce it. Despite having information about heart disease, vulnerable women with chest pain sought medical attendance less than non-vulnerable women (p=0.0l); and are blamed by physicians. Women consider they lack sufficient information about how to reduce the risk of coronary disease, and blame themselves when ill. Conclusions: There are vulnerability conditions in women that modulate a low perception of their being at risk, and the scarcity of health care practices.

Antecedentes: las enfermedades cardiovasculares constituyen la primera causa de morbimortalidad a nivel mundial y nacional; sobresale la enfermedad coronaria. Esto ha contribuido para que el tratamiento quirúrgico de revascularización miocárdica sea considerado como un procedimiento de rutina. Éste es uno de los avances más importantes de la medicina durante el siglo XX. En Bogotá, los registros estadísticos muestran que más del 50% del total de cirugías cardiovasculares corresponde a ella. Objetivo: realizar la caracterización de pacientes que se encuentran en posoperatorio temprano de revascularización miocárdica, quienes presentan cambios fisiológicos en su esfera biológica, secundarios al procedimiento, a nivel neurológico, cardiovascular, respiratorio, gastrointestinal, de eliminación y de la piel. Metodología: se realizó un estudio descriptivo, de seguimiento prospectivo. Se observaron y revisaron las historias clínicas de 151 pacientes en posoperatorio de 48 a 96 horas. La revisión de la historia clínica se realizó por el investigador. Se consignó la información en una hoja de registro de información y se procesó mediante métodos de análisis exploratorio multidimensional: análisis factorial de correspondencias múltiples combinado con el Método Cluster de Clasificación. Resultados: estuvieron relacionados con clases de pacientes de acuerdo con los eventos clínicos presentes en cada uno de los sistemas estudiados donde se evidencia que presentan alteración de los sistemas neurológico, cardiovascular, respiratorio y de la piel. Conclusión: la caracterización de los pacientes en posoperatorio de una revascularización miocárdica permite que el cuidado de enfermería sea enfocado hacia la solución de problemas de los sistemas antes mencionados.

Background: cardiovascular diseases are the leading cause of morbidity and mortality at global and national level; stands out coronary disease. This has contributed to make the surgical treatment of coronary artery bypass grafting being considered a routine procedure. This is one of the most important advances in medicine during the twentieth century. In Bogota, statistical records show that more than 50% of all cardiovascular surgeries corresponds to it. Objective: to characterize patients who are in early postoperative myocardial revascularization, who present physiological changes secondary to procedure, in the biological area at neurological, cardiovascular, respiratory, and gastrointestinal level, elimination system and skin. Methodology: a descriptive study was performed and followed prospectively. The medical records of 151 patients in postoperative 48 to 96 hours were seen and reviewed. The review of the medical history was performed by the researcher. The information was collected on a recording sheet and then recorded and processed by methods of multidimensional exploratory analysis: Multiple correspondence analysis combined with Cluster Classification Method. Results: they were related to the kind of patient according to clinical events present in each of the studied systems where there is evidence of alteration of the neurological, cardiovascular and respiratory systems, and skin. Conclusion: the characterization of patients in postoperative of myocardial revascularization allows nursing care to be focused on solving problems of the aforementioned systems.

Identification of coronary heart disease in asymptomatic individuals with diabetes mellitus: to screen or not to screen / Identificación de enfermedad cardiaca coronaria en individuos asintomáticos con diabetes mellitus: Tamizar o no tamizar

Coronary heart disease (CHD) is highly prevalent in patients with diabetes mellitus (DM), and remains the single most common cause of death among this population. Regrettably, a significant percentage of diabetics fail to perceive the classic symptoms associated with myocardial ischemia. Among asymptomatic diabetics, the prevalence of abnormal cardiac testing appears to be high, raging between 10% and 62%, and mortality is significantly higher in those with abnormal scans. Hence, the potential use of screening for CHD detection among asymptomatic DM individuals is appealing and has been recommended in certain circumstances. However, it was not until recently, that this question was addressed in clinical trials. Two studies randomized a total of 2,023 asymptomatic diabetics to screening or not using cardiac imaging with a mean follow up of 4.4 ±1.4 yrs. In combination, both trials showed lower than expected annual event rates, and failed to reduce major cardiovascular events in the screened group compared to the standard of care alone. The results of these trials do not currently support the use of screening tools for CHD detection in asymptomatic DM individuals. However, these studies have important limitations, and potential explanations for their negative results that are discussed in this manuscript.

La enfermedad de la arterias coronarias (EAC) es muy prevalente en pacientes con diabetes mellitus (DM), y continúa siendo la principal causa de muerte en estos pacientes. Desafortunadamente, muchos diabéticos pueden carecer de síntomas de alerta en la presencia de isquemia miocárdica, por lo cual el diagnóstico de EAC puede ocurrir de manera tardía. Estudios observacionales han sugerido que la prevalencia de isquemia miocárdica puede ser alta en diabéticos asintomáticos (10 al 62% según la serie) y la mortalidad es mayor en esos pacientes. Por esto, el uso de pruebas para detección de EAC en el paciente diabético asintomático parece atractivo y es recomendado en ciertas circunstancias. Sin embargo, no fue si no hasta hace poco que dos estudios investigaron el verdadero rol de estas pruebas de manera randomizada. En conjunto, 2,023 pacientes diabéticos asintomáticos fueron aleatorizados a recibir o no una prueba para detección de EAC y fueron seguidos en promedio por 4.4 ±1.4 años. Al final de seguimiento, ambos estudios mostraron menos eventos cardiovasculares de los esperados, y el uso de pruebas para detección de EAC no redujo la tasa de eventos cardiovasculares comparado al no uso de estas pruebas. Los resultados de estos ensayos clínicos no soportan actualmente el uso de estas pruebas en el paciente diabético asintomático. Sin embargo, estos estudios tienen limitaciones importantes, y posibles hipótesis para explicar los resultados que son discutidas en el artículo.

Factor reumatoide con marcadores de riesgo aterogénico en pacientes con artritis reumatoide / Rheumatoid factor with atherogenic risk markers in rheumatoid arthritis patients

INTRODUCCIÓN: el factor reumatoide ha sido el autoanticuerpo más asociado a la artritis reumatoide. A pesar de los avances logrados en el conocimiento de su patogenia, el análisis de la relación entre este anticuerpo y marcadores de riesgo coronario no ha sido agotado en esta enfermedad. OBJETIVOS: evaluar la asociación del factor reumatoide con los marcadores de riesgo coronario lipoproteína (a), índices apolipoproteína B/apolipoproteína A1, LDL/HDL colesterol, Apolipoproteína B/LDL colesterol e índice aterogénico; así como el valor predictivo de dicho anticuerpo sobre estos marcadores. MÉTODOS: se realizó un estudio observacional analítico y transversal en una muestra de pacientes portadores de artritis reumatoide y controles, aparente sanos, de la provincia de Matanzas, en el período junio/2011 a marzo/2014. El programa estadístico SPSS fue empleado para el análisis de los resultados. RESULTADOS: el factor reumatoide mostró asociación con los índices aterogénico, LDL/HDL colesterol y Apolipoproteína B/LDL colesterol; utilidad para estimar los dos primeros, y valor predictivo sobre el índice aterogénico independiente de los marcadores de actividad de la enfermedad: proteína c reactiva, C3 complemento, C4 complemento, y DAS28 en pacientes con la variedad seropositiva para éste autoanticuerpo [r de Pearson = 0,632; 0,345; (-) 0,359; R2= 0,406; 0,119 (p < 0,05), al respecto]. CONCLUSIONES: la presente investigación demostró relación, valor predictivo, y posible estratificación del riesgo coronario indirecto, a partir del título sérico de factor reumatoide IgM en pacientes con artritis reumatoide seropositiva; y motiva a profundizar el estudio de igual problema científico con autoanticuerpos asociados a enfermedades autoinmunes relacionadas con elevada morbimortalidad cardiovascular.

INTRODUCTION: rheumatoid factor is the autoantibody most commonly associated with rheumatoid arthritis. Despite the considerable progress achieved in the study of its pathogenesis, further analysis is required of the relationship between this antibody and coronary risk markers. OBJECTIVES: evaluate the association between rheumatoid factor and the coronary risk markers lipoprotein(a), apolipoprotein B / apolipoprotein A1, LDL / HDL cholesterol, apolipoprotein B / LDL cholesterol, and atherogenic index, as well as the predictive value of this antibody with respect to such markers. METHODS: an observational cross-sectional analytical study was conducted of a sample of patients with rheumatoid arthritis and apparently healthy controls from the province of Matanzas from June 2011 to March 2014. Results were analyzed with the statistical software SPSS. RESULTS: rheumatoid factor showed an association with atherogenic indices, LDL / HDL cholesterol and apolipoprotein B / LDL cholesterol, as well as usefulness to estimate the first two and predictive value for the atherogenic index irrespective of markers of disease activity: C-reactive protein, C3 complement, C4 complement and DAS28 in patients seropositive for this autoantibody [Pearson r = 0.632; 0.345; (-) 0.359; R2= 0.406; 0.119 (p < 0.05), respectively]. CONCLUSIONS: the study showed the relationship, predictive value and possible indirect stratification of coronary risk based on the serum levels of rheumatoid factor IgM in patients with seropositive rheumatoid arthritis. Further examination should be conducted of this scientific problem in reference to autoantibodies associated with autoimmune diseases of high cardiovascular morbidity and mortality.

The Diagonal Earlobe Crease is the first extracardiac sign of Coronary Heart Disease (CHD), associated with generalized atherosclerosis. There is controversy about its validity. Objective: Determine sign’s prevalence in hospitalized population with very-high cardiovascular risk, of a medical center in the southern area of Santiago-Chile, and recognize its association with CHD and Cerebrovascular Disease (CVD). Method: Case and control study. 304 male patients, >60 years-old, with personal CHD medical history and hospitalized between May and December of 2012 at El Pino Hospital were included. They were divided in 2 groups, evaluating the presence/absence of DELCby photography. Group 1: submitted to coronarography with significant obstruction (>50 percent stenosis) in >1 coronary artery. Group 2: submitted to simple brain computed tomography with hypodensity of cerebral parenchyma, effacement of sulci, brain edema and/or intraparenchymatous hemorrhage. Controls we redefined as patients wich result of interventions lack the described injuries. Case-Control ratio of 1:1. The sign’s prevalence was determined. The results where adjusted according to cardiovascular risk factors, by conditional logistic regression. Results: Prevalence of DELC in cases (56.96 percent), was higher than controls(43.04 percent) (p<0.01). DELC Odds Ratio: CHD = 2.79 [1.14-6.83](p<0.03), and CVD = 2,55 [1.19–5.48] (p<0.02). Conclusion: This study identified a significative difference between prevalence in both groups, similar with the tendency described in literature. This study, also detected a significant positive association, independent of cardiovascular risk factors, between DELC with CHD and CVD...

Consumo de álcool e risco para doença coronariana na região metropolitana de São Paulo: uma análise do Projeto GENACIS / Alcohol consumption pattern and Coronary Heart Disease risk in Metropolitan São Paulo: analyses of GENACIS Project

OBJETIVOS: Examinar a associação entre consumo de álcool e risco para doença coronariana em amostra populacional. MÉTODOS: Estudo transversal, de base populacional, conduzido de janeiro/2006 a junho/2007, na região metropolitana de São Paulo, como parte do estudo internacional (Gender, Alcohol, and Culture: an International Study). Os sujeitos (1.501, sendo 609 homens e 892 mulheres) eram residentes da região metropolitana de São Paulo, tinham 30 anos ou mais de idade e foram selecionados aleatoriamente, a partir de amostragem complexa por conglomerados. Todos os indivíduos consentiram em participar da pesquisa. A variável dependente foi risco cardíaco avaliado através do WHO Rose Angina Questionnaire. A análise multivariada consistiu em regressão logística, tendo sido realizado ajuste para uso de tabaco e índice de massa corpórea. RESULTADOS: A taxa de resposta foi 75%. Ser mulher, ter mais idade, ser negro, fumante e ter um índice de massa corpórea elevado, foram associados a maior risco para doença coronariana. Indivíduos que nunca beberam na vida (OR = 2,22) e ex-bebedores (OR = 2,42) tiveram maior risco de doença cardíaca do que aqueles que informaram beber até 19 g de álcool por dia, sem episódios de beber excessivo. Entre os que tiveram episódios de embriaguês observou-se uma tendência a maior risco (OR = 3,95, p = 0,09). CONCLUSÕES: Nossos achados sugerem um menor risco para doença coronariana entre os bebedores moderados. Destaca-se que os estudos que avaliam o impacto do álcool sobre doença cardíaca precisam identificar o padrão de uso de álcool dos sujeitos, visto que este aspecto pode modificar o risco.

OBJECTIVES: To examine the association between patterns of drinking and coronary heart disease (CHD) risk in a populational sample. METHODS: A population-based cross-sectional study carried out from January 2006 to June 2007, in Metropolitan São Paulo, Brazil, in conjunction with the international collaborative GENACIS project (Gender, Alcohol, and Culture: an International Study), with PAHO support. The subjects (1,501; 609 men, 892 women) of this study were residents of randomly chosen households aged 30 years and above who consented to provide information. The dependent variable was cardiac risk as assessed by the WHO Rose Angina Questionnaire. Logistic Regression analysis was used and the data were adjusted for Body Mass Index (BMI) and smoking. RESULTS: The response rate was 75%. Being female, older, African-American, a current smoker, and having a greater BMI were associated with higher risk of coronary heart disease. Lifetime abstainers (OR = 2.22) and former drinkers (OR = 2.42) had greater CHD risk than those who consumed up to 19g pure alcohol per day, with no binge. Among those who had binged weekly or more there was a tendency toward higher risk (OR = 3.95, p = .09). CONCLUSIONS: Our findings suggest a lower risk for CHD among moderate drinkers. It is important, in studies which were investigating cardiac risk, assess heavy alcohol use, since it can change that risk. Also, effective public policies are needed to reduce harmful drinking and related morbidity in Brazil. .

Design and baseline characteristics of a coronary heart disease prospective cohort: two-year experience from the strategy of registry of acute coronary syndrome study (ERICO study)

OBJECTIVES: To describe the ERICO study (Strategy of Registry of Acute Coronary Syndrome), a prospective cohort to investigate the epidemiology of acute coronary syndrome. METHODS: The ERICO study, which is being performed at a secondary general hospital in São Paulo, Brazil, is enrolling consecutive acute coronary syndrome patients who are 35 years old or older. The sociodemographic information, medical assessments, treatment data and blood samples are collected at admission. After 30 days, the medical history is updated, and additional blood and urinary samples are collected. In addition, a retinography, carotid intima-media thickness, heart rate variability and pulse-wave velocity are performed. Questionnaires about food frequency, physical activity, sleep apnea and depression are also applied. At six months and annually after an acute event, information is collected by telephone. RESULTS: From February 2009 to September 2011, 738 patients with a diagnosis of an acute coronary syndrome were enrolled. Of these, 208 (28.2%) had ST-elevation myocardial infarction (STEMI), 288 (39.0%) had non-ST-elevation myocardial infarction (NSTEMI) and 242 (32.8%) had unstable angina (UA). The mean age was 62.7 years, 58.5% were men and 77.4% had 8 years or less of education. The most common cardiovascular risk factors were hypertension (76%) and sedentarism (73.4%). Only 29.2% had a prior history of coronary heart disease. Compared with the ST-elevation myocardial infarction subgroup, the unstable angina and non-ST-elevation myocardial infarction patients had higher frequencies of hypertension, diabetes, prior coronary heart disease (p<0.001) and dyslipidemia (p = 0.03). Smoking was more frequent in the ST-elevation myocardial infarction patients (p = 0.006). CONCLUSIONS: Compared with other hospital registries, our findings revealed a higher burden of CV risk factors and less frequent prior CHD history.

Asociación entre evento coronario y factores de riesgo psicosociales: agotamiento vital, ansiedad e ira en una población de Argentina. Estudio de correlación entre factores de riesgo / [Association between acute coronary events and psychosocial risk factors: vital exhaustion, anxiety and anger in an Argentinian population. A correlation study between risks factors].

OBJECTIVE: To study the association between vital exhaustion, anxiety and anger with acute coronary event; second, determine whether they are associated with each other, and third, if the joint interaction of two or more factors increases the risk for coronary event. METHOD: We conducted a case-control study with 165 patients, both sexes, between 35 and 75 years, 90 patients with acute ischemic coronary event and 75 controls hospitalized with an acute event of non-ischemic cardiac causes. RESULTS: Statistically significant differences between the control group and the ischemic coronary group for vital exhaustion was found (OR = 3.0 (1.6-5.5) p < 0.001 (chi2)). Psychosocial risk factors are associated each with p < 0.001: anxiety and vital exhaustion (Spearman Rho = 0.58), anger and vital exhaustion (Spearman Rho = 0.41) and anxiety and anger (Spearman Rho = 0.38). The simultaneous presence of vital exhaustion and anxiety increases the probability of an acute ischemic coronary event (p < 0.01). CONCLUSIONS: In this study we found a significative association between vital exhaustion and acute ischemic coronary event, psychosocial risk factors are associated with each other and simultaneous presence of vital exhaustion and anxiety increases the probability of an acute ischemic coronary event.

Standard surgical treatment for benign prostatic hyperplasia is safe for patients over 75 years: analysis of 100 cases from a high-volume urologic center

OBJECTIVES: In this study, we aimed to determine the complications of standard surgical treatments among patients over 75 years in a high-volume urologic center. METHODS: We analyzed 100 consecutive patients older than 75 years who had undergone transurethral prostatic resection of the prostate or open prostatectomy for treatment of benign prostatic hyperplasia from January 2008 to March 2010. We analyzed patient age, prostate volume, prostate-specific antigen level, international prostatic symptom score, quality of life score, urinary retention, co-morbidities, surgical technique and satisfaction with treatment. RESULTS: Median age was 79 years. Forty-eight patients had undergone transurethral prostatic resection of the prostate, and 52 had undergone open prostatectomy. The median International Prostatic Symptom Score was 20, the median prostate volume was 83 g, 51% were using an indwelling bladder catheter, and the median prostatespecific antigen level was 5.0 ng/ml. The most common comorbidities were hypertension, diabetes and coronary disease. After a median follow-up period of 17 months, most patients were satisfied. Complications were present in 20% of cases. The most common urological complication was urethral stenosis, followed by bladder neck sclerosis, urinary fistula, late macroscopic hematuria and persistent urinary incontinence. The most common clinical complication was myocardial infarction, followed by acute renal failure requiring dialysis. Incidental carcinoma of the prostate was present in 6% of cases. One case had urothelial bladder cancer. CONCLUSIONS: Standard surgical treatments for benign prostatic hyperplasia are safe and satisfactory among the elderly. Complications are infrequent, and urethral stenosis is the most common. No clinical variable is associated with the occurrence of complications.

Assessment of cardiovascular risk of patients with arterial hypertension of a public health unit / Avaliação do risco cardiovascular de indivíduos portadores de hipertensão arterial de uma unidade pública de saúde

Objective: To assess the cardiovascular risk, using the Framingham risk score, in a sample of hypertensive individuals coming from a public primary care unit. Methods: The caseload comprised hypertensive individuals according to criteria established by the JNC VII, 2003, of 2003, among 1601 patients followed up in 1999, at the Cardiology and Arterial Hypertension Outpatients Clinic of the Teaching Primary Care Unit, at the Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo. The patients were selected by draw, aged over 20 years, both genders, excluding pregnant women. It was a descriptive, crosssectional, observational study. The Framingham risk score was used to stratify cardiovascular risk of developing coronary artery disease (death or non-fatal acute myocardial infarction). Results: Age range of 27-79 years (x = 63.2 ± 9.58). Out of 382 individuals studied, 270 (70.7%) were female and 139 (36.4%) were characterized as high cardiovascular risk for presenting diabetes mellitus, atherosclerosis documented by event or procedure. Out of 243 stratified patients, 127 (52.3%) had HDL-C < 50 mg/dL; 210 (86.4%) had systolic blood pressure greater than or equal to 120 mmHg; 46 (18.9%) were smokers; 33 (13.6%) had a high cardiovascular risk. Those added to 139 enrolled directly as high cardiovascular risk, totaled up 172 (45%); 77 (20.2%) of medium cardiovascular risk and 133 (34.8%) of low risk. The highest percentage of high cardiovascular risk individuals was aged over 70 years; those of medium risk were aged over 60 years; and the low risk patients were aged 50 to 69 years. Conclusion: The significant number of high and medium cardiovascular risk individuals indicates the need to closely follow them up.

Objetivo: Identificar o risco cardiovascular, por meio do escore de risco de Framinghan, em uma amostra de hipertensos de uma unidade pública de saúde. Métodos: A casuística foi constituída por hipertensos, segundo critérios do JNC VII, 2003, de 2003, dentre 1.601 acompanhados no ano de 1999 no Ambulatório de Cardiologia e Hipertensão Arterial do Centro Saúde Escola da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo. Os pacientes foram selecionados por sorteio, com idade acima de 20 anos, ambos os gêneros, excluindo-se as gestantes. Tratou-se de estudo observacional descritivo e transversal. Utilizou-se o Escore de Risco de Framinghan para estratificação do risco cardiovascular para desenvolvimento de doença arterial coronária (morte ou infarto agudo do miocárdio - não fatal). Resultados: A idade variou de 27 a 79 anos (x = 63,2 ± 9,58). Dos 382 indivíduos estudados, 270 (70,7%) eram mulheres e 139 (36,4%) foram caracterizados como de alto risco cardiovascular por apresentarem diabetes mellitus, aterosclerose documentada por evento ou procedimento. Dos 243 estratificados, 127 (52,3%) apresentaram HDL-C < 50 mg/dL; 210 (86,4%) apresentaram pressão arterial sistólica maior ou igual a 120 mmHg; 46 (18,9%) eram fumantes; 33 (13,6%) eram de alto risco cardiovascular - que somados aos 139 incluídos diretamente como alto risco cardiovascular, totalizaram 172 (45%); 77 (20,2%) eram de médio risco cardiovascular e 133 (34,8%) de baixo risco. O maior percentual de indivíduos de alto risco cardiovascular situou-se acima 70 anos; de médio risco, acima de 60 anos; e de baixo risco entre 50 e 69 anos. Conclusão: O número significativo de indivíduos de alto e médio risco cardiovascular indica a necessidade de um acompanhamento mais próximo dos mesmos.

Diferencias en la aterosclerosis coronaria entre hombres y mujeres con Diabetes Mellitus tipo 2 evaluados con el Score de Gensini / Differences in coronary atherosclerosis assessed with the Gensini score between men and women with type 2 Diabetes

Antecedentes y Objetivos: Las mujeres diabéticas tienen mayor morbi-mortalidad asociada a eventos coronarios isquémicos que los hombres. Este estudio describe la extensión, magnitud y severidad de la ateros-clerosis coronaria entre hombres y mujeres con diabetes mellitus tipo 2. Métodos: Estudio de tipo descriptivo que incluyó a 162 pacientes diabéticos consecutivos con sospecha de aterosclerosis coronaria y estudiados con coronariogra-fía. La magnitud de la aterosclerosis fue cuantificada utilizando el Score de Gensini. Resultados: La edad promedio fue 64.8 años. Noventa y cuatro eran mujeres (58.0 por ciento). El tiempo de evolución de la diabetes fue mayor para mujeres que para hombres (152.1 +/- 90.0 vs 120.2 +/- 99.4 meses) respectivamente (p<0.05). Las mujeres tuvieron un índice de masa corporal (30.5 +/- 5.1), superior al de los hombres (28.5 +/- 5.2) (p<0.05). La aterosclerosis coronaria significativa estuvo presente en el 61.7 por ciento de toda la población diabética, siendo en hombres de 76.5 por ciento versus 51.5 por ciento en mujeres (odds ratio: 1.5). El número de placas ateroscle-róticas fue 195 en 68 hombres (2,86 placa/paciente) y de 168 en 94 mujeres (1,78 placa/paciente) (p<0.0043). La presencia de aterosclerosis significativa en 1, 2 y 3 vasos se observó en el 7.4 por ciento; 17.6 por ciento y 51.5 por ciento de los hombres, respectivamente, versus el 12.8 por ciento; 10.6 por ciento y 27.7 por ciento en las mujeres, (p<0.0002). La magnitud de la enfermedad coronaria medida con el Score de Gensini fue 69.4 +/- 66.7 en hombres versus 35.6 +/- 47.3 en mujeres (p<0.005). Conclusión: En este estudio observamos que hombres diabéticos tienen mayor extensión, magnitud y severidad de aterosclerosis coronaria que las mujeres diabéticas.

Diabetic women have higher morbidity and mortality associated with ischemic coronary events than diabetic men, but the extension of coronary artery disease in both groups is less well established. Aim: to compare the extension, magnitude and severity of coronary atherosclerosis between men and women with type 2 diabetes mellitus. Method: 162 consecutive diabetic patients with suspected coronary atherosclerosis studied by coronary angiography were included. The magnitude of atherosclerosis was quantified using the Gensini Score. Results: The average age was 64.8 years. Ninety-four patients were women (58.0 percent). Diabetes was present for 152 +/- 90.0 months for women and 120 +/- 99.4 months for men (p <0.05). Women had a higher body mass index (30.5 +/- 5.1) than men (28.5 +/- 5.2, p<0.05). The presence of significant coronary atherosclerosis in the entire diabetic population was of 61.7 percent: 76.5 percent in men and 51.5 percent in women (OR 1.5). The mean number of atherosclerotic plaques was 195 in 68 men (2.86 plaques/patient) and 168 in 94 women (1.78 plaques/patient, p=0.0043). Significant atherosclerosis in 1, 2 and 3 vessels was observed in 7.4 per cent, 17.6 percent and 51.5 percent of men, respectively, versus 12.8 percent, 10.6 percent and 27.7 percent in women (p<0.0002). The magnitude of coronary disease measured by Gensini Score was 69.4 + 66.7 in men versus 35.6 +/- 47.3 in women (p<0.005). Conclusion: Men with diabetes have greater extension, magnitude and severity of coronary atherosclerosis than diabetic women.
