Observational, cross-sectional, and retrospective study

Resumen Objetivo: Determinar las características clínico-epidemiológicas, viabilidad diagnóstica de la poligrafía respiratoria domiciliaria y el tratamiento de pacientes con sospecha de apnea obstructiva del sueño (AOS) en riesgo cardiovascular. Métodos: Se realizó estudio observacional, transversal, descriptivo en pacientes atendidos en un servicio de consulta externa de cardiología con sospecha de AOS, de enero de 2015 a diciembre de 2019. La información se obtuvo de los expedientes médicos, se aplicó análisis estadístico descriptivo. Resultados: Se examinaron 138 expedientes, de las poligrafías respiratorias domiciliarias fueron descartadas solo el 8% por no cumplir con los estándares de calidad requeridos. Se demostró que el 89% padecían AOS, un 60% moderada a severa; predominó en hombres después de los 50 años. El principal ractores de riesgo cardiovascular fue hipertensión (89%). La cardiopatía más prevalente fue la hipertensiva (52%). Se optimizó tratamiento farmacológico cardiovascular en el 82% de los casos. Rehabilitación cardiaca en el 30%, ventilación mecánica no invasiva 41%, modalidad fija 33% y autoajustable 9%, todos con telemetría. Conclusiones: La prevalencia y severidad de la AOS es mayor en presencia de riesgo o enfermedad cardiovascular establecida. Ante la sospecha clínica es factible confirmar el diagnóstico con poligrafía respiratoria domiciliaria por el nivel de precisión y la menor infraestructura requerida. Es necesaria una mayor participación del cardiólogo en el diagnóstico y tratamiento de este trastorno por el riesgo significativo de enfermedad cardiovascular que representa.

Abstract Objective: To determine the clinical-epidemiological characteristics, diagnostic feasibility of home respiratory polygraphy and treatment of patients with suspected obstructive sleep apnea (OSA) at cardiovascular risk. Methods: An observational, cross-sectional, descriptive study was conducted in patients seen in a cardiology outpatient service with suspected OSA, from January 2015 to December 2019. The information was obtained from medical records, and a descriptive statistical analysis was applied to this information. Results: 138 files were reviewed; only 8% of the home respiratory polygraphs were discarded, because they did not meet the required quality standards. It was demonstrated that 89% suffered from OSA, 60% moderate to severe; in men after 50 years of age. The main cardiovascular risk factors was hypertension (89%). The most prevalent heart disease was hypertension (52%). Cardiovascular pharmacological treatment was improved in 82% of the cases. Cardiac rehabilitation in 30%, noninvasive mechanical ventilation 41%, fixed modality 33%, and self-adjustable 9%, all with telemetry. Conclusions: The prevalence and severity of OSA is higher in the presence of risk or established cardiovascular disease. In the presence of clinical suspicion, it is feasible to confirm the diagnosis with home respiratory poligrafy due to the level of precision and the lower infrastructure required. Greater involvement of the cardiologist in the diagnosis and treatment of this disorder is necessary due to the significant risk of cardiovascular disease it represents.

Proteína C reactiva, aspectos cardiovasculares de una proteína de fase aguda: una actualización para el médico / C-reactive protein, cardiovascular issues of an acute-phase protein: an update for the clinician

Resumen La inflamación es un factor patogénico importante para el desarrollo de la enfermedad cardiovascular aterosclerótica. Actualmente, el biomarcador utilizado con mayor frecuencia que refleja la inflamación sistémica es la proteína C reactiva (PCR), una proteína de fase aguda producida principalmente por los hepatocitos bajo la influencia de la interleucina 6, la interleucina 1 beta y el factor de necrosis tumoral. La evidencia proveniente de estudios epidemiológicos ha demostrado una fuerte asociación entre las concentraciones elevadas de PCR en suero o plasma y la incidencia de un primer evento cardiovascular (incluido infarto agudo de miocardio, accidente vascular cerebral isquémico y muerte cardíaca súbita) en la población general, así como la recurrencia de eventos cardiovasculares adversos en los pacientes con enfermedad establecida. El valor aditivo que la medición de la PCR otorga a los factores de riesgo tradicionales se refleja en novedosas calculadoras de riesgo cardiovascular y en los actuales regímenes de intervención, que ya consideran a la PCR como objetivo terapéutico. Sin embargo, las variaciones en los niveles de PCR, que dependen del sexo, la etnia, el estado hormonal y algunas peculiaridades de los ensayos de medición, deben tenerse en cuenta al decidir implementar la PCR como un biomarcador útil en el estudio y el tratamiento de la enfermedad cardiovascular aterosclerótica. Esta revisión pretende ofrecer una visión actualizada de la importancia de medir la PCR como biomarcador de riesgo cardiovascular más allá de los factores tradicionales que estiman el riesgo de enfermedad aterosclerótica.

Abstract Inflammation is an important pathogenic factor for the development of atherosclerotic cardiovascular disease. Currently, the most frequently used biomarker reflecting systemic inflammation is C-reactive protein (CRP), an acute-phase protein produced primarily by hepatocytes under the influence of interleukin-6, interleukin-1 beta, and tumor necrosis factor. Growing evidence from epidemiological studies has shown a robust association between elevated serum or plasma CRP concentrations and the incidence of a first cardiovascular adverse event (including acute myocardial infarction, ischemic stroke, and sudden cardiac death) in the general population, as well as recurrence of major adverse cardiovascular events among patients with established disease. The additive value that CRP measurement gives to traditional risk factors is reflected in novel cardiovascular risk calculators and in current intervention regimens, which already consider CRP as a target therapeutic. However, the variations in CRP levels, that depend on sex, ethnicity, hormonal status, and some peculiarities of the measurement assays, must be taken into consideration when deciding to implement CRP as a useful biomarker in the study and treatment of atherosclerotic cardiovascular disease. This review aims to offer an updated vision of the importance of measuring CRP levels as a biomarker of cardiovascular risk beyond the traditional factors that estimate the risk of atherosclerotic disease.

Asociación entre los marcadores lipídicos en la infancia/ adolescencia y los eventos cardiovasculares en la adultez: una revisión sistemática / Association between lipid markers in childhood/ adolescence and cardiovascular events in adulthood: A systematic review

Introducción. La asociación entre los marcadores lipídicos en la infancia/adolescencia y la incidencia de eventos clínicos cardiovasculares en la adultez está poco explorada en la literatura. El objetivo de esta revisión sistemática fue analizar la evidencia disponible sobre este tema. Población y métodos. Esta revisión sistemática se realizó de acuerdo con las guías PRISMA. Se realizó una búsqueda bibliográfica para detectar los estudios que evaluaron la asociación entre los niveles lipídicos en la edad pediátrica y la incidencia de eventos cardiovasculares en la edad adulta. No hubo restricciones idiomáticas ni geográficas en la búsqueda. Resultados. En total, cinco estudios observacionales (todas cohortes prospectivas) que incluyeron 43 540 pacientes fueron identificados y considerados elegibles para este estudio. Cuatro estudios evaluaron el nivel de triglicéridos; todos reportaron una asociación significativa entre este marcador en la edad pediátrica y los eventos cardiovasculares en la adultez. Un estudio reportó la misma asociación con el nivel de colesterol total, mientras que otro evidenció el valor predictivo de la lipoproteína (a) para el mismo desenlace clínico. Un solo estudio evaluó el colesterol asociado a lipoproteínas de alta densidad (C-HDL), sin encontrar una relación con el punto final de interés. El análisis del colesterol asociado a lipoproteínas de baja densidad (C-LDL) arrojó resultados contradictorios, aunque la asociación fue significativa en los estudios con un tamaño muestral más grande y con un mayor número de eventos durante el seguimiento. Conclusión. Los datos de esta revisión sugieren que las alteraciones de los marcadores lipídicos en la infancia y la adolescencia se asocian con un mayor riesgo cardiovascular en la adultez temprana y media.

Introduction. The association between lipid markers in childhood/adolescence and the incidence of clinical cardiovascular events in adulthood has been little explored in the bibliography. The objective of this systematic review was to analyze available evidence on this topic. Population and methods. This systematic review was conducted in accordance with the PRISMA guidelines. A comprehensive bibliographic search was done to find studies assessing the association between lipid levels in childhood and the incidence of cardiovascular events in adulthood. There were no language or geographic restrictions. Results. A total of 5 observational studies (all prospective cohorts) including 43 540 patients were identified and considered eligible for this study. Four studies assessed triglyceride levels; all reported a significant association between this lipid marker in childhood and cardiovascular events in adulthood. A study reported the same association with total cholesterol level, while another showed the predictive value of lipoprotein (a) for the same clinical outcome. Only one study assessed high-density lipoprotein cholesterol (HDL-C), but it did not find an association with the endpoint of interest. The analysis of lowdensity lipoprotein cholesterol (LDL-C) showed contradictory results, although the association was significant in the studies with a larger sample size and a higher number of events during follow-up. Conclusion. According to this review, alterations in lipid markers in childhood and adolescence are associated with a higher cardiovascular risk in early and middle adulthood.

Resumen Antecedentes: El 31 de diciembre de 2019, se inició una de las pandemias más graves de los últimos tiempos. Se ha descrito que ciertas condiciones de salud, como la obesidad y la diabetes mellitus, están relacionadas con desenlaces desfavorables por COVID-19. Objetivo: Identificar factores asociados a mortalidad en pacientes con COVID-19. Material y métodos: Cohorte retrospectiva de 998 639 pacientes. Se analizaron las características sociodemográficas y clínicas de los pacientes, y se compararon supervivientes con fallecidos. Se utilizó el modelo de riesgos proporcionales de Cox para la identificación de variables predictivas de defunción por COVID-19. Resultados: Entre los fallecidos, los hombres representaron 64.3 % y las mujeres 35.7 %, diferencia que resultó estadísticamente significativa. Las personas con más de 80 años presentaron un riesgo 13 veces mayor de morir por COVID-19 (IC 95 % = 12.469,13.586) y la enfermedad renal crónica, un riesgo de 1.5 (IC 95 % = 1.341, 1.798); la diabetes mellitus tuvo un riesgo de 1.25 (IC 95 % = 1.238,1.276). Conclusiones: La edad, el sexo, la diabetes mellitus y la obesidad resultaron ser entidades predictivas de muerte por COVID-19. Se sugiere más investigación relacionada con enfermedad pulmonar obstructiva crónica, enfermedades cardiovasculares, tabaquismo y embarazo.

Abstract Background: On December 31, 2019, one of the most serious pandemics in recent times made its appearance. Certain health conditions, such as obesity and diabetes mellitus, have been described to be related to COVID-19 unfavorable outcomes. Objective: To identify factors associated with mortality in patients with COVID-19. Material and methods: Retrospective cohort of 998,639 patients. Patient sociodemographic and clinical characteristics were analyzed, with survivors being compared with the deceased individuals. Cox proportional hazards model was used to identify variables predictive of COVID-19-associated mortality. Results: Among the deceased patients, men accounted for 64.3%, and women, for 35.7%, with the difference being statistically significant. Subjects older than 80 years had a 13-fold higher risk of dying from COVID-19 (95% CI = 12,469, 13,586), while chronic kidney disease entailed a risk 1.5 times higher (95% CI = 1,341, 1,798), and diabetes mellitus involved a risk 1.25 times higher (95% CI = 1.238,1.276). Conclusions: Age, sex, diabetes mellitus and obesity were found to be predictors of COVID-19 mortality. Further research related to chronic obstructive pulmonary disease, cardiovascular diseases, smoking and pregnancy is suggested.

Introduction: a new type of coronavirus that was named SARSCoV-2, responsible for the COVID-19 disease, with rapid spread in the world, due to high transmission that resulted in pandemic. There were 2'397,216 confirmed cases, with 162,956 deaths in the world, according to the WHO in April 2020. However, hypertension affects 40% of adults and means that around 250 million people suffer from high blood pressure. The WHO, according to its reports, refers that hypertension is the number one risk factor for death. One in four Mexicans suffers from high blood pressure. Objectives: to establish the incidence of systemic arterial hypertension after suffering from COVID-19 in patients of the UMF No. 48. Material and methods: it is a cross-sectional, observational and descriptive study, consisting of 3,238 patients with a positive COVID-19 diagnosis of both sexes, aged 18-70 years. Through the formula for infinite populations a sample of 348 patients is obtained. Will proceed with review of files in the Family Medicine Information System, version 6.2, to obtain the corresponding information. Results: 27 patients diagnosed with hypertension after the diagnosis of COVID-19, 52% of the male sex and 48% of the female sex, with a mean age of 39 years; 74% corresponds to a mild illness by COVID-19 and 26% to moderate disease. A median of 8 days per period of infection by COVID-19 is documented. In the female circle, the average onset of hypertension was 13 months and as for the male sex, the mean development of hypertension after COVID-19 was six months (AU)

Systematic review of pharmacoeconomic evaluation on PCSK9 inhibitors for the prevention of cardiovascular disease in patients with hypercholesterolemia / 中国药房

OBJECTIVE To systematically review the pharmacoeconomic evaluation literature about proprotein convertase subtilisin/kexin type 9 （PCSK9） inhibitors for the prevention of cardiovascular disease in patients with hypercholesterolemia， and to provide a reference for clinical treatment， health decision-making and future follow-up research. METHODS Retrieved from English and Chinese databases such as PubMed and CNKI， the pharmacoeconomic literature about PCSK9 inhibitors （evolocumab and alirocumab） for the prevention of cardiovascular disease in patients with hypercholesterolemia was collected from the establishment of the database to October 8， 2023. The quality of the included literature was assessed with Consolidated Health Economic Evaluation Reporting Standards 2022 （CHEERS 2022） scale. The descriptive analysis was performed for basic information， model structure， related parameters， sensitivity analysis and the results of included studies. RESULTS & CONCLUSIONS A total of 29 literature were included， with overall good quality. The evaluation mainly adopted the Markov model from the healthcare system， payer and societal perspective. The effectiveness and utility data mainly came from the previous studies； the direct cost was mainly considered with a discount rate of 1.5%-5.0% per year， while the willingness-to-pay threshold was often set at 1-3 times the gross domestic product per capita. Most health output indicators were measured in life years and quality-adjusted life years. The sensitivity analysis of most studies demonstrated the robustness and the main influential factor was the drug cost. Most Chinese studies showed that PCSK9 inhibitor was not cost-effective for the prevention of cardiovascular disease in patients with acute coronary syndrome， myocardial infarction and atherosclerotic cardiovascular disease. It was cost-effective to use PCSK9 inhibitors for the prevention of cardiovascular disease only in specific groups， such as patients with triple vessel disease， patients with newly diagnosed acute coronary syndrome and low-density lipoprotein cholesterol≥100 mg/dL. Future research should refer to the CHEERS 2022 scale to improve the design， and strive to select large-scale， high-quality data to enhance the quality of reports and the transparency of health decisions， so as to more accurately assess the cost-effectiveness of PCSK9 inhibitors.

ObjectiveTo investigate the high-risk detection rate and aggregation of cardiovascular diseases（CVD） in 8 districts of Shanghai and influencing factors， and to provide scientific references for prevention and control of CVD. MethodsBased on the Cardiovascular Disease Screening and Management Program in Shanghai from 2016 to 2021， 104 685 participants aged 35 to 75 in 8 districts of Shanghai were selected for analysis. χ2 test and multivariate logistic regression were used for statistical analysis of the influencing factors of CVD and aggregation of CVD. ResultsThe proportion of high-risk CVD individuals in the population was 19.17%， including the high-risk individuals with hypertension （8.65%）， dyslipidemia （6.33%）， CVD history （5.58%）， and WHO assessed risk ≥20% types （2.69%）， respectively. Old age， overweight and obesity， central obesity， smoking， drinking， farmers， unmarried， and low family income were the risk factors of CVD， while high education level was the protective factor. In the participants， 16 323 people （81.34%） were classified as CVD high-risk groups； The number of aggregation of 1， 2 and ≥3 high risk types of CVD were 16 323（81.34%）， 3 236（16.13%）， 509（2.54%）， respectively. Old age， low education level， low annual family income， farmers， unmarried， smoking， drinking， overweight， obesity and central obesity were associated with the risk of aggregation of high risk types of CVD， and the correlation strength increased with the increase of aggregation types. ConclusionThe prevention and control of CVD in Shanghai should focus on the hypertension， elderly， overweight， obesity， central obesity， smoking， drinking， low educated， low family income， farmers and unmarried people， and targeted intervention measures should be taken to reduce the risk of CVD among residents.

Targeting ferroptosis and ferritinophagy: new targets for cardiovascular diseases / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Cardiovascular diseases (CVDs) are a leading factor driving mortality worldwide. Iron, an essential trace mineral, is important in numerous biological processes, and its role in CVDs has raised broad discussion for decades. Iron-mediated cell death, namely ferroptosis, has attracted much attention due to its critical role in cardiomyocyte damage and CVDs. Furthermore, ferritinophagy is the upstream mechanism that induces ferroptosis, and is closely related to CVDs. This review aims to delineate the processes and mechanisms of ferroptosis and ferritinophagy, and the regulatory pathways and molecular targets involved in ferritinophagy, and to determine their roles in CVDs. Furthermore, we discuss the possibility of targeting ferritinophagy-induced ferroptosis modulators for treating CVDs. Collectively, this review offers some new insights into the pathology of CVDs and identifies possible therapeutic targets.

Mediating effect of lifestyle on the relationship between family history and cardiovascular disease / 公共卫生与预防医学

Objective To evaluate the mediating effect of lifestyles on the association between family history and cardiovascular disease (CVD). Methods This study was based on the "Early Screening and Comprehensive Intervention of High-risk Populations of Cardiovascular Disease Project". The data were collected from 6 project sites in Hubei Province. Logistic regression analysis was used to investigate the impact of family history and lifestyle on CVD, and the relationship between family history and lifestyle. Mediation analysis was used to evaluate the mediating effect of lifestyle on the association between family history and CVD. Results A total of 5 871 subjects were included in the study from 2015 to 2016, of whom 500 (8.52%) developed CVD and 484 had family history of CVD. The risk of developing CVD was significantly increased in participants with family history of disease (OR = 1.458, P = 0.014) and in those with high level of physical activity (OR = 1.081, P = 0.026). The increase of leisure physical activity time showed a protective effect on developing CVD (OR = 0.977, P < 0.001). Participants with family history significantly increased leisure physical activity (OR = 2.085, P < 0.001), and were less likely to choose occupations with high levels of physical activity (OR = 0.524, P < 0.001). The results of mediation analysis showed that leisure physical activity and occupational physical activity mediated the relationship between family history and CVD, and the β value of the mediating effects were -0.004 (P = 0.010) and 0.002 (P = 0.045), respectively. The β value of the direct effect of family history on CVD was 0.033 (P < 0.05). Conclusion Leisure physical activity and occupational physical activity might mediate the relationship between family history and CVD. People with family history would reduce the risk of developing CVD by increasing leisure physical activity time and choosing occupations with low levels of physical activity.

The impact of diabetes and subclinical hypothyroidism association with coronary artery calcium: results from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)

ABSTRACT Objective: We aimed to analyze the association of diabetes and subclinical hypothyroidism with subclinical atherosclerosis measured by coronary artery calcium (CAC) in the baseline of the ELSA-Brasil study. Materials and methods: CAC was measured using a 64-detector computed tomographic scanner. The association of CAC > 0 was presented as an odds ratio (OR) and 95% confidence intervals (95%CI) in logistic models and as β (95%CI) in linear models after multivariable adjustment for confounders. Results: We analyzed 3,809 participants (mean-age (SD) 50.5 (8.8); 51.7% women). In the main analysis, we did not find an association of diabetes and subclinical hypothyroidism with CAC. However, in stratified analysis according to age strata, we found no significative interaction terms, an important heterogeneity between the groups, with the younger age strata showing an association of the group with both diseases and CAC > 0 (OR 7.16; 95%CI, 1.14; 44.89) with a wide but significative 95%CI, suggesting that the smaller number of participants in the younger group may influence the results. Our findings also showed an association of CAC > 0 and log (CAC+1) with diabetes in logistic (OR, 1.31; 95%CI, 1.05-1.63) and linear models (β, 0.24, 0.16, 0.40), respectively. Diabetes was independently associated with CAC > 0 in linear models. Discussion: In conclusion, our results showed a great heterogeneity in stratified analysis based on age in the younger age strata. Although we found no significant interaction factors, the smaller sample size for the analysis may influence the negative findings.

A pilot observational study to identify reference values for the 6-minute walk test in Brazilian people with hypertension / Um estudo observacional piloto para identificar valores de referência para o teste de caminhada de 6 minutos em hipertensos brasileiros

Abstract Introduction Systemic arterial hypertension (SAH) is responsible for 9.5 million deaths in the global popu-lation. Lifestyle factors, including physical inactivity, are important modifiable risk factors in the development of SAH. Thus, physical exercise has been shown to be effective to control SAH and before the prescription, the six-minute walk test (6-MWT) has been commonly used to assess the physical capacity. Objective To propose reference values for the 6-MWT test in Brazilian people with SAH. Methods A cross-sectional observational study was conducted with 302 hypertensive subjects (62.61 + 10.93 years) admitted to a cardiac rehabilitation program. Participants were divided into different age quartiles and submitted to 6-MWT. The walking distance data was compared between the quartiles and adjusted by mul-tiple linear regression analysis. Results The hypertensive subjects walked 388.07 + 115.03 m during the 6-MWT. No significant difference between the genders was found. However, when the age quartiles were compared, for the 46-59 age group, the women walked less than the men. Intra-group comparisons showed that the distance walked in the 6-MWT decreased with the increase in age, in both men and women. Conclusion The present study provides reference values for the 6-MWT, both for Brazilian men and women of different age groups. This data may be an important parameter for future clinical studies, prevention strategies, and clinical intervention.

Resumo Introdução A hipertensão arterial sistêmica (HAS) é respon-sável por 9,5 milhões de mortes na população mundial. Con-dições do estilo de vida, incluindo a inatividade física, são importantes fatores de risco modificáveis no desenvolvimento da HAS. Desse modo, o exercício físico tem se mostrado eficaz no controle da HAS e, antes da prescrição, o teste de caminhada de seis minutos (TC6) tem sido comumente utilizado para ava-liar a capacidade física. Objetivo Propor valores de referência para o teste de TC6 em brasileiros com HAS. Métodos Realizou-se um estudo observacional transversal com 302 hipertensos (62,61 + 10,93 anos) admitidos em um programa de reabilitação cardíaca. Os participantes foram divididos em diferentes quartis de idade e submetidos ao TC6. Os dados de distância percorrida foram comparados entre os quartis e ajustados por análise de regressão linear múltipla. Resultados Os hipertensos caminharam 388,07 + 115,03 m durante o TC6. Não encontrou-se diferença significativa entre os gêneros. No entanto, quando comparados os quartis de idade, para a faixa etária de 46 a 59 anos, as mulheres caminharam menos do que os homens. As comparações intragrupo mostraram que a distância percorrida no TC6 diminuiu com o aumento da idade, tanto em homens quanto em mulheres. Conclusão O presente estudo fornece valores de referência para o TC6, tanto para homens quanto para mulheres brasileiras de diferentes faixas etárias. Esses dados podem ser um parâmetro importante para futuros estudos clínicos, estratégias de prevenção e intervenção clínica.

Impact of the COVID-19 pandemic isolation concerning physical activity and cardiovascular health / Impacto do isolamento da pandemia de COVID-19 na atividade física e na saúde cardiovascular

Background: Regular physical activity (PA) is essential for health maintenance and disease prevention. COV-ID-19 and its social isolation affected patients with cardiovascular (CV) disease. This is a scoping review aiming to map, analyze, and summarize the impacts caused by the isolation of the COVID-19 pandemic concerning PA and CV health in adults. Methods: The review was based on PRISMA-ScR. PubMed, PubMed Central, BVS/BIREME, Scopus, Web of Science, CINAHL, Brazilian Digital Library of Theses and Dissertations, and SciELO databases were selected to search. Two search phases were performed: May 2021 and March 2022. English-language full-text papers were included. Initially, the titles and abstracts of the retrieved documents were read and screened based on the research question. A third reviewer resolved disagreement through consensus meetings. An assessment form was adapted for data extraction. The study was registered in the Open Science Framework platform under the DOI https://doi.org/10.17605/OSF.IO/AH6P8. Results: 11 papers were included and demonstrated that regular PA could be challenging in social isolation environments. Most participants were moderately active and performed low-intensity PA. Confinement led to the limitation of everyday activities, nutritional disorders, and reduced PA, contributing to weight gain. Quarantine was associated with stress and depression, leading to an unhealthy diet (AU).

Introdução: A prática regular de atividade física (AF) é essencial para a manutenção da saúde e prevenção de doenças. A COVID-19 e seu isolamento social afetaram pacientes com doenças cardiovasculares (CV) na prática dessas atividades. Desta forma, realizou-se uma revisão de escopo com o objetivo de mapear, analisar e sintetizar os impactos causados pelo isolamento da pandemia de COVID-19 na realização de AF e na saúde CV em adultos. Métodos: A revisão foi baseada no PRISMA-ScR. Foram selecionadas para a pesquisa a PubMed, PubMed Central, BVS/BIREME, Scopus, Web of Science, CINAHL, Biblioteca Digital Brasileira de Teses e Dissertações e bases de dados SciELO. Duas fases de busca foram realizadas: maio de 2021 e março de 2022. Foram incluídos artigos que possuíam texto completo em inglês. Inicialmente, os títulos e resumos dos documentos recuperados foram lidos e triados com base na questão de pesquisa. Um terceiro revisor foi utilizado para avaliar os desacordos por meio de reuniões de consenso. Um formulário de avaliação foi adaptado para extração de dados. O estudo foi registrado na plataforma Open Science Framework sob o DOI https://doi.org/10.17605/OSF.IO/AH6P8. Resultados: 11 artigos foram incluídos neste estudo e demonstraram que a AF regular pode ser desafiadora em ambientes de isolamento social. A maioria dos participantes era moderadamente ativa e praticava AF de baixa intensidade. O confinamento levou à limitação das atividades cotidianas, distúrbios nutricionais e diminuição da AF, contribuindo para o ganho de peso. A quarentena foi associada ao estresse e à depressão, levando a uma dieta pouco saudável. Possíveis soluções apontam para a realização de AF domiciliar, considerando a saúde basal e o estado CV. Conclusão: A era pós-COVID-19 e suas consequências apontam para a necessidade de planejamento de estratégias que aumentem e mantenham a AF domiciliar como medida protetora para a população em geral, considerando saúde CV, recursos e espaço domiciliar (AU).

La carga de enfermedades cardiovasculares en México, 1990-2021. Un resumen del estudio Global Burden of Disease 2021 / The burden of cardiovascular disease in Mexico 1990-2021. Summary of the Global Burden of Disease 2021 study

Resumen Antecedentes: La enfermedad cardiovascular (ECV) es una causa importante de mortalidad, con implicaciones económicas para el sistema de salud. Objetivo: Caracterizar la carga de ECV en México de 1990 a 2021 con base en el estudio Global Burden of Disease (GBD), para abordar la carga de salud y enfermedad, sus implicaciones en la salud pública y el desarrollo del sistema de atención médica. Material y métodos: Se describe la mortalidad de las ECV en México y se examina en qué medida el crecimiento y el envejecimiento de la población explican las tendencias, las diferencias por sexo y los patrones geográficos. Resultados: Las ECV representan la primera causa de mortalidad, principalmente por cardiopatía hipertensiva, hemorragia intracerebral, hemorragia subaracnoidea, cardiopatía isquémica y accidente cerebrovascular isquémico. Se observó un cambio de tendencia en hombres y mujeres, mayor mortalidad en mayores de 80 años y en estados del norte del país. Conclusiones: México debe invertir en programas de salud pública para abordar los riesgos modificables, promover el envejecimiento saludable y reducir la muerte prematura por ECV.

Abstract Background: Cardiovascular disease (CVD) is a major cause of mortality, with economic implications for the health system. Objective: To characterize the burden of CVD in Mexico from 1990 to 2021 based on the Global Burden of Disease (GBD) study, to address the burden of health and disease, its implications for public health and for the development of the health care system. Material and methods: CVD mortality in Mexico is described, and the extent to which population growth and aging explain the observed trends, sex differences, and geographic patterns is examined. Results: CVD is the leading cause of mortality, mainly due to hypertensive heart disease, intracerebral hemorrhage, subarachnoid hemorrhage, ischemic heart disease and ischemic stroke. A change of trend was observed in men and women, with higher mortality in people older than 80 years and in the northern states of the country. Conclusions: Mexico must invest in public health programs to address modifiable risks, promote healthy aging, and reduce premature death due to CVD.

Enfermedad arterial periférica en población trabajadora: factores de riesgo y estilo de vida

Introducción: La Enfermedad Arterial Periférica (EAP) es definida como la oclusión de las arterias de las extremidades, se reconoce como la tercera causa de morbilidad vascular aterosclerótica, después del infarto agudo de miocardio y el accidente cerebrovascular. Aunque las enfermedades cardiovasculares se han relacionado con la ocupación, la información sobre la relación entre el trabajo con la EAP es escasa. Objetivo: Identificar la prevalencia de EAP en población laboralmente activa y su relación con variables sociodemográficas, clínicas y estilo de vida. Metodología: Se realizó un estudio analítico de tipo transversal, en 203 sujetos de 40 años o más, laboralmente activos de Popayán. Tras la firma del consentimiento, se realizó una entrevista, y se registraron las variables sociodemográficas y clínicas. Para el tamizaje de EAP se evaluó el índice tobillo brazo (ITB). Los participantes se clasificaron en categorías basadas en el ITB de la siguiente manera: EAP ≤ 0,90; 0,91 a 0,99 normal; y no compresible > 1,40. Los datos fueron analizados con el programa SPSS versión 26.0, se aplicó la prueba de Kolmogorov-Smirnov como prueba de normalidad, la t Student para evaluar diferencias de medias entre los grupos de estudio y la prueba de Chi-cuadrado. Resultados y discusión: La prevalencia fue del 2,5 % para EAP, siendo el primer estudio reportado para población trabajadora en Colombia. La EAP fue más prevalente en empleados manuales (2,8 %) e ingresos bajos (30 %); además, fueron obesos y fumadores. El riesgo encontrado para edad fue OR 1,5; IC95 % 1,17 a 2,14, género OR 1,2; IC95 % 1,20 a 3,28 y DM2 OR 1,5; IC95 % 1,23 a 6,68. Conclusión: Se estableció por primera vez la prevalencia de EAP (2,5 %) en una población laboralmente activa de Popayán, siendo más prevalente en los individuos con ingresos bajos, expuestos a factores de riesgo cardiovascular y con antecedente familiar de DM2.

Introduction: The Peripheral Arterial Disease (PAD) is defined as the occlusion of the extremities' arteries, and it is known to be the third vascular atherosclerotic cause of death after acute myocardial infarction and brain stroke. Even though cardiovascular diseases had been linked to occupation, information about the relation between PAD and labor activity runs short. Objective: To identify the PAD prevalence in the working population and its relationship with sociodemographic, clinical and lifestyle variables. Methodology: A cross-sectional analytical study was conducted in 203 people of >40 years, actively working in the city of Popayán. After consent signing, interviews were completed to record such variables. PAD testing was evaluated through Ankle-Brachial Index (ABI). Participants were grouped into categories based on ABI as follows: PAD ≤0.90; normal 0.91 to 0.99; and non-compressible >1.40. Collected data was analyzed in SPSS version 26.0, applying Kolmogorov-Smirnov test as the normal; t Student test to evaluate mean differences between study groups and Chi-square. Results and discussion: PAD prevalence was 2.5 % being the very first report done for Colombia's working class. PAD was prevalent for manual-labor employees (2.8 %), low-income people (30 %), adding obesity and smoking to their profile. Age risk found was (OR 1.5; IC 95 % 1.17 to 2.14), by gender (OR 1.2; IC 95 % 1.20 to 3.28); DM2 (OR 1.5; IC 95 % 1.23 to 6.68). Conclusion: It was determined for the first time a prevalence of (2.5 °%) PAD for a population actively working in Popayán, being more frequent with individuals with low income, people exposed to higher cardiovascular risks, and for people with family DM2 records.

Marcadores lipídicos en los pacientes con VIH/sida en tratamiento con inhibidores de la proteasa

Introducción: Las enfermedades cardiovasculares constituyen la principal causa de morbimortalidad a escala mundial. Otra enfermedad con impacto significativo en los sistemas de salud pública es el VIH/sida. Los pacientes infectados con el virus de la inmunodeficiencia humana, tienen mayor riesgo de desarrollar enfermedades cardiovasculares. Posterior al tratamiento antirretroviral ha disminuido la incidencia de enfermedades oportunistas asociadas al VIH/sida, y se ha elevado la incidencia de enfermedades asociadas al envejecimiento, como la enfermedad cardiovascular. El uso de antirretrovirales inhibidores de la proteasa se asocia a hiperlipidemia y, por consiguiente, al aumento de complicaciones cardiovasculares. Objetivo: Determinar los marcadores lipídicos en pacientes con VIH/sida en tratamiento con inhibidores de la proteasa. Materiales y métodos: Se realizó un estudio observacional, analítico, transversal en los pacientes con VIH/sida de la provincia de Matanzas, durante el período comprendido entre marzo y agosto de 2020, en el Laboratorio Clínico del Hospital Universitario Clínico Quirúrgico Comandante Faustino Pérez Hernández. Resultados: Se evaluaron los marcadores lipídicos como factor de riesgo cardiovascular asociado al tratamiento antirretroviral, siendo los triglicéridos el de mayor incidencia. Conclusiones: Se identificaron los marcadores lipídicos como factores de riesgo cardiovascular, en este caso la hipertrigliceridemia.

Introduction: Cardiovascular diseases are the main risk of morbidity and mortality worldwide. Another disease with significant impact on public health systems is HIV/AIDS. Patients infected with the human immunodeficiency virus have a higher risk of developing cardiovascular diseases. After antiretroviral treatment, the incidence of opportunistic diseases associated with HIV/AIDS has decreased and the incidence of diseases associated with aging such as cardiovascular disease has increased. The use of protease inhibitor antiretroviral drugs is associated with hyperlipidemia and a consequent increase in cardiovascular complications. Objective: To determine lipid markers in patients with HIV/AIDS undergoing treatment with protease inhibitors. Materials and method: An observational, analytical, cross-sectional study was carried out in patients with HIV/AIDS from the province of Matanzas during the period from March to August 2020, in the Clinical Laboratory of the Provincial Teaching Clinical Surgical Hospital Faustino Pérez Hernandez. Results: Lipid markers were evaluated as cardiovascular risk factor associated with antiretroviral treatment, with triglycerides being the one of highest incidence. Conclusions: Lipid markers were identified as cardiovascular risk factors; in this case hypertriglyceridemia.

Perfil de riesgo cardiovascular en mujeres de tres entornos de la Provincia de Tucumán - Argentina / Cardiovascular risk profile in women from three different areas of the Province of Tucumán, Argentina

RESUMEN Introducción : El rol del entorno sobre la salud en la población femenina de Tucumán está poco estudiado. El objetivo del presente trabajo fue evaluar el perfil de riesgo cardiovascular de mujeres de los entornos rural, periurbano y urbano de la provincia de Tucumán (Argentina). Material y métodos : Se efectuó un estudio analítico transversal en 3 grupos de mujeres de Tucumán: rural (n=125), periurbano (n= 50) y urbano (n=112). Resultados : La presión arterial (PA) fue menor en el grupo rural; el grupo urbano presentó mayor frecuencia cardíaca y menor circunferencia de cuello. El 29,7% de las mujeres presentaron sobrepeso y el 42,4% obesidad, sin diferencia significativa entre los 3 grupos. La circunferencia de cuello estuvo aumentada en el 62% de las mujeres del grupo rural, 79% del periurbano y 41% del urbano (p<0,001). El grupo urbano presentó más frecuentemente tabaquismo. En los grupos urbano y periurbano fue mayor la proporción de mujeres con estudios superiores (p <0,001). El nivel educativo se correlacionó positivamente con la frecuencia cardíaca. Conclusiones : Independientemente del entorno las mujeres de Tucumán presentan sobrepeso u obesidad asociados a otros factores de riesgo para enfermedad cardiovascular. Ello debe ser tenido en cuenta para la elaboración de políticas y la toma de conductas a fin de mejorar su pronóstico.

ABSTRACT Background : The role of the environment on female population health in Tucumán has been little studied. This study aimed to evaluate the cardiovascular risk profile in women from rural, peri-urban and urban areas in the province of Tucumán (Argentina) and to analyse their differences. Methods : An analytical cross-sectional study was conducted in 3 groups of women from Tucumán: rural (n = 125), peri-urban (n = 50) and urban (n = 112). Results : Blood pressure (BP) was lower in the rural group; the urban group showed higher heart rate and smaller neck cir cumference. Of the studied women, 29.7% were overweight and 42.4% obese, and no significant differences were found in the 3 groups. Increased neck circumference was observed in 62% of women in the rural group, 79% in the peri-urban group and 41% in the urban group (p <0.001). Smoking was more frequent in the urban group. In the urban and peri-urban groups, the proportion of women with higher education level was greater (p <0.001). Education level was positively correlated with heart rate. Conclusion : Regardless of the environment, women from Tucumán are overweight or obese and have other risk factors for cardiovascular disease. This should be considered when planning policies and making decisions in order to improve their prognosis.

Introduction: In Cuba and in the rest of the world, cardiovascular diseases are recognized as a major and growing public health problem, which causes high mortality. Objective: To design a predictive model to estimate the risk of cardiovascular disease based on artificial intelligence techniques. Methods: The data source was a prospective cohort including 1633 patients, followed for 10 years. The data mining tool Weka was used and attribute selection techniques were employed to obtain a smaller subset of significant variables. To generate the models, the rule algorithm JRip and the meta-algorithm Attribute Selected Classifier were applied, using J48 and Multilayer Perceptron as classifiers. The obtained models were compared and the most used metrics for unbalanced classes were applied. Results: The most significant attribute was history of arterial hypertension, followed by high and low density lipoprotein cholesterol, high sensitivity c-reactive protein and systolic blood pressure; all the prediction rules were derived from these attributes. The algorithms were effective to generate the model. The best performance was obtained using the Multilayer Perceptron, with a true positive rate of 95.2percent and an area under the ROC curve of 0.987 in the cross validation. Conclusions: A predictive model was designed using artificial intelligence techniques; it is a valuable resource oriented to the prevention of cardiovascular diseases in primary health care(AU)
