Cardiovascular risk assessment in Portugal's primary health care system: SCORE vs. SCORE2.

INTRODUCTION AND OBJECTIVES: The 2021 European Society of Cardiology guidelines on cardiovascular disease (CVD) prevention introduced the more accurate SCORE2 risk model as a replacement for the earlier SCORE, which is still used in primary care software in Portugal. Our objective is to determine whether the difference between risk assessment using SCORE and SCORE2, in the same patient population, is statistically significant. METHODS: A total of 1642 patients aged 40-65 without previous CVD, from the medical records of two Family Health Units, were included in this cross-sectional study. SCORE and SCORE2 were calculated using the variables gender, age, smoking status, lipid profile and systolic blood pressure. A statistical analysis was performed on the results. RESULTS: Using SCORE, 98% of the patients were in the low-moderate risk categories and 2% in the high or very high risk categories. When using SCORE2, the corresponding percentages were 55% and 45%, respectively. Reclassification with SCORE2 into higher categories was more often observed in younger (under 50 years of age) and male patients. With SCORE, 38.61% of patients were within the LDL-C target range; this figure fell to 20.28% with SCORE2. These differences are statistically significant (p<0.0001). CONCLUSION: Our findings show that a significant number of patients in this cohort who were classified through SCORE at lower risk levels were reclassified into higher risk categories with SCORE2. Similarly, the number of patients within the LDL-C target range for LDL-C was also lower using SCORE2.

High prevalence of cardiovascular disease and risk factors among type 2 diabetes patients followed in a hospital setting in Portugal: The PICT2RE observational study.

INTRODUCTION AND OBJECTIVES: Portugal is a country with a high prevalence of type 2 diabetes (T2D) and cardiovascular disease (CVD). The prevalence of CVD and cardiovascular (CV) risk factors among T2D patients followed in hospitals in Portugal is not known. The primary objective of this study was to assess the prevalence of CVD and CV risk factors among T2D patients in a hospital setting in Portugal. The clinical management of CVD in the hospital setting was also assessed. METHODS: We performed a non-interventional, multicenter, cross-sectional study with a retrospective phase. T2D patients were consecutively invited to participate. Data were collected retrospectively. RESULTS: A total of 715 patients were included in the study. Mean age and diabetes duration were 66.6 and 17.4 years, respectively. Of these, 286 patients (40.0%) had been diagnosed with CVD, mostly ischemic heart disease (50.4%). All patients had at least one CV risk factor. CVD was significantly associated with hypertension, hypercholesterolemia, low high-density lipoprotein cholesterol, hypertriglyceridemia and smoking. During the three years prior to study inclusion, the incidence of hyperglycemic episodes and T2D complications increased among patients with established CVD, but the numbers of hospitalization episodes and specialist appointments remained stable. An improvement was observed in key cardiometabolic risk factors. CONCLUSIONS: Our study revealed a high prevalence of CVD and CV risk factors among a sample of T2D patients in a hospital setting. Patients with established CVD seem to be adequately managed but further efforts are needed at the prevention stage for better control of risk factors and morbidity.

Global warming and heat wave risks for cardiovascular diseases: A position paper from the Portuguese Society of Cardiology.

Global warming is a result of the increased emission of greenhouse gases. The consequences of this climate change threaten society, biodiversity, food and resource availability. The consequences include an increased risk of cardiovascular (CV) disease and cardiovascular mortality. In this position paper, we summarize the data from the main studies that assess the risks of a temperature increase or heat waves in CV events (CV mortality, myocardial infarction, heart failure, stroke, and CV hospitalizations), as well as the data concerning air pollution as an enhancer of temperature-related CV risks. The data currently support global warming/heat waves (extreme temperatures) as cardiovascular threats. Achieving neutrality in emissions to prevent global warming is essential and it is likely to have an effect in the global health, including the cardiovascular health. Simultaneously, urgent steps are required to adapt the society and individuals to this new climatic context that is potentially harmful for cardiovascular health. Multidisciplinary teams should plan and intervene healthcare related to temperature changes and heat waves and advocate for a change in environmental health policy.

Impact of genetic information on coronary disease risk in Madeira: The GENEMACOR study.

INTRODUCTION: Coronary artery disease (CAD), characterized by an atherogenic process in the coronary arteries, is one of the leading causes of death in Madeira. The GENEMACOR (GENEs in MAdeira and CORonary Disease) study sought to investigate the main risk factors - environmental and genetic - and estimate whether a genetic risk score (GRS) improves CAD prediction, discrimination and reclassification. METHODS: Traditional risk factors and 33 CAD genetic variants were considered in a case-control study with 3139 individuals (1723 patients and 1416 controls). The multivariate analysis assessed the likelihood of CAD. A multiplicative GRS (mGRS) was created, and two models (with and without mGRS) were prepared. Two areas under receiver operating characteristic curve (area under curve (AUC)) were analyzed and compared to discriminate CAD likelihood. Net reclassification improvement (NRI) and integrated discrimination index (IDI) were used to reclassify the population. RESULTS: All traditional risk factors were strong and independent predictors of CAD, with smoking being the most significant (OR 3.25; p<0.0001). LPA rs3798220 showed a higher CAD likelihood (odds ratio 1.45; p<0.0001). Individuals in the fourth mGRS quartile had an increased CAD probability of 136% (p<0.0001). A traditional risk factor-based model estimated an AUC of 0.73, rising to 0.75 after mGRS inclusion (p<0.0001), revealing a better fit. Continuous NRI better reclassified 28.1% of the population, and categorical NRI mainly improved the reclassification of the intermediate risk group. CONCLUSIONS: CAD likelihood was influenced by traditional risk factors and genetic variants. Incorporating GRS into the traditional model improved CAD predictive capacity, discrimination and reclassification. These approaches may provide helpful diagnostic and therapeutic advances, especially in the intermediate risk group.

Myocardial T1 mapping with magnetic resonance imaging - a useful tool to understand the diseased heart.

Cardiac magnetic resonance imaging (MRI) is increasingly used in clinical practice due to its versatility. T1 mapping of the myocardium, a recently introduced MRI technique that is becoming available enables quantitative tissue characterization, overcoming some of the limitations of late enhancement. This promising technique has the ability to identify diffuse myocardial fibrosis and is beginning to be used in the diagnostic and prognostic assessment of several heart diseases. In this review, we start by explaining the physical principles of myocardial T1 mapping and possible confounding factors in its measurement. We then analyze the evidence supporting its potential usefulness as a complement to the existing cardiac MRI methods. Finally, we discuss the current limitations of T1 mapping and possible areas of future research.

Long-term outcomes of primary cardiovascular prevention: A retrospective study at a referral center in Portugal.

INTRODUCTION AND OBJECTIVES: Lifestyle changes are frequently insufficient to reduce cardiovascular (CV) risk in patients with dyslipidemia. This study aims to characterize the long-term evolution of lipid profile and CV risk of patients under primary prevention. METHODS: A retrospective study was performed of outpatients at a Portuguese cardiovascular risk clinic with ≥2 CV risk factors, followed for ≥2 years between 1995 and 2015. Statin therapy had been initiated early, in accordance with the clinic's practice. After written informed consent was obtained, sociodemographic and clinical characteristics were collected from medical charts, at baseline and last visit. Changes in lipid profile and CV risk scores were estimated. Associations between HDL-C or LDL-C changes and gender, age, observation time and treatments were assessed through bivariate analysis and multiple linear regression models. RESULTS: Out of 516 participants with mean follow-up of 11.4±4.3 years, 56.6% were female and 91.5% received statins. Lipid profile showed statistically significant improvement, including median changes in LDL-C and HDL-C of -77.0 mg/dl and +19 mg/dl, respectively. CV risk also showed statistically significant improvements according to all scores. Statin therapy resulted in a mean HDL-C increase of 7.4 mg/dl (independently of gender and other treatments) and a mean LDL-C reduction of 51.8 mg/dl (irrespective of age and other treatments). CONCLUSION: Results from this long-term real-life study indicate that primary prevention, specifically early and continuous therapy with intermediate-intensity statins as an add-on to lifestyle interventions, was important in obtaining consistent and adequate metabolic correction in patients with additional risk factors.

Air pollution and cardiovascular diseases: A position paper.

Air pollution is one of the main environmental risk factors for health and is linked to cardiovascular diseases, which are the leading cause of mortality worldwide. In this position paper, we discuss the main air pollutants and how they can promote the development of cardiovascular disease or cardiovascular events. We also summarise the main evidence supporting the association between air pollution and cardiovascular events, such as coronary events (acute coronary syndromes/myocardial infarction; chronic coronary syndromes), stroke, heart failure and mortality. Some recommendations are made based on these data and the European Society of Cardiology guidelines on cardiovascular disease prevention, acknowledging that it is important to increase awareness and literacy on this topic in Portugal.

Cadmium and cardiovascular disease: An overview of pathophysiology, epidemiology, therapy, and predictive value.

Cadmium is a widely distributed toxic heavy metal that has been associated with many diseases including chronic renal dysfunction, osteomalacia, acute heart failure, secondary hypertension, and atherosclerosis. Although several studies have suggested that cadmium may affect multiple systems by inducing lipid per oxidation in cells and disturbing the antioxidant system, the mechanism by which cadmium affects the cardiovascular system remains unclear. Recent studies on heart failure and acute myocardial infarction have shown that cadmium has good predictive ability for mortality in patients with cardiovascular disease. In this study, we briefly review the role of cadmium in cardiovascular disease, which may prompt further studies to investigate the potential association between cadmium and mortality in patients with cardiovascular disease.

Patient and caregiver productivity loss and indirect costs associated with cardiovascular events in Portugal.

OBJECTIVES: To present the Portuguese results of a multi-country cross-sectional survey aiming to estimate productivity loss in the first year after an acute coronary syndrome (ACS) or stroke. METHODS: Patients previously hospitalized for ACS or stroke were enrolled during a routine cardiology/neurology visit 3-12 months after the index event and ≥4 weeks after returning to work. Productivity loss for the patient and the caregiver in the previous four weeks were reported by the patient using the validated iMTA Productivity Cost Questionnaire (iPCQ). Hours lost were converted into eight-hour work days and prorated to one year, combined with initial hospitalization and sick leave, and valued according to Portuguese labor costs. RESULTS: The analysis included 39 employed patients with ACS (mean age 51 years, 80% men, 95% with myocardial infarction, mean left ventricular ejection fraction 55%) and 31 with stroke (mean age 50 years, 80% men, all ischemic, 77% with modified Rankin Scale 0-1); 41% of ACS and 10% of stroke patients had a history of cardiovascular disease. Mean (SD) productivity loss for patients and caregivers was 47 (62) work days for ACS and 76 (101) work days for stroke. ACS patients lost 37 (39) and caregivers lost 10 (42) work days. Stroke patients and caregivers lost 65 (78) and 12 (38) work days, respectively. Total mean indirect cost per case was €5403 (€7095) and €8726 (€11558) for employed patients with ACS and stroke, respectively. CONCLUSIONS: The annual proportions of productive time lost by employed patients due to ACS and stroke in Portugal were 17% and 27%, respectively. Caregivers of these patients lost about 5% of their annual productive time.

Impact of public health initiatives on acute coronary syndrome fatality rates in Portugal.

INTRODUCTION AND OBJECTIVE: Every year cardiovascular disease (CVD) causes 3.9 million deaths in Europe. Portugal has implemented a set of public health policies to tackle CVD mortality: a smoking ban in 2008, a salt reduction regulation in 2010 and the coronary fast-track system (FTS) for acute coronary syndrome (ACS) in 2007. Our goal in this study was to analyze the impact of these three public health policies in reducing case-fatality rates from ACS between 2000 and 2016. METHODS: The impact of these policies on monthly ACS case-fatalities was assessed by creating individual models for each of the initiatives and implementing multiple linear regression analysis, using standard methods for interrupted time series. We also implemented segmented regression analysis to test which year showed a significant difference in the case-fatality slopes. RESULTS: Separate modeling showed that the smoking ban (beta=-0.861, p=0.050) and the FTS (beta=-1.27, p=0.003) had an immediate impact after implementation, but did not have a significant impact on ACS trends. The salt reduction regulation did not have a significant impact. For the segmented model, we found significant differences between case-fatality trends before and after 2009, with rates before 2009 showing a steeper decrease. CONCLUSIONS: The smoking ban and the FTS led to an immediate decrease in case-fatality rates; however, after 2009 no major decrease in case-fatality trends was found. Coronary heart disease constitutes an immense public health problem and it remains essential for decision-makers, public health authorities and the cardiology community to keep working to reduce ACS mortality rates.

Contribuições da vitamina D no tratamento de sintomas depressivos e fatores de risco cardiovascular: protocolo de estudo para um ensaio clínico randomizado, duplo-cego e controlado por placebo.

ABSTRATO: FUNDO: A depressão é uma das principais causas de incapacidade crônica em todo o mundo e um importante fator de risco cardiovascular, aumentando o risco relativo de doença arterial coronariana, bem como as taxas de morbimortalidade cardiovascular. Concomitantemente à alta prevalência de depressão, houve uma redução na exposição à luz solar com o aumento da urbanização e do uso de protetores solares, o que levou a uma redução nos níveis séricos de 25-hidroxivitamina D. Portanto, este artigo descreve uma protocolo para um ensaio clínico com o objetivo de avaliar os efeitos da suplementação de vitamina D na depressão e fatores de risco cardiovascular para contribuir com evidências sobre a influência potencial da suplementação na regulação do humor. MéTODOS: Este estudo de protocolo foi orientado pelos itens de protocolo padrão: recomendações para ensaios intervencionistas. Um ensaio clínico randomizado, controlado por placebo, duplo-cego será realizado envolvendo 224 adultos (faixa etária de 18 a 60 anos) com depressão que estão tomando antidepressivos e não têm histórico de suplementação de vitamina D, comorbidades psiquiátricas, doença renal crônica, hipercalcemia, ou neoplasia. Os participantes serão recrutados nos ambulatórios psiquiátricos de duas universidades do nordeste do Brasil. Os participantes elegíveis que fornecerem consentimento por escrito serão designados aleatoriamente para o grupo de intervenção (n = 112; suplementação de vitamina D 50.000 UI por semana durante 6 meses) ou para o grupo controle (n = 112; placebo tomado semanalmente por 6 meses). Medidas para monitorar sintomas depressivos, exames clínicos e exames laboratoriais para avaliar fatores de risco cardiovascular e níveis séricos de vitamina D serão realizadas antes e após o período de intervenção. DISCUSSãO: Até onde sabemos, este será o primeiro ensaio clínico com o objetivo de testar a eficácia da suplementação de vitamina D na redução do risco cardiovascular e como um adjuvante à terapia da depressão por um período prolongado (6 meses). Os resultados contribuirão para a compreensão dos efeitos terapêuticos da suplementação de vitamina D no tratamento da depressão e podem ajudar a orientar políticas públicas direcionadas à suplementação de vitamina para a redução do risco cardiovascular.

Physical fitness and activity, metabolic profile, adipokines and endothelial function in children.

OBJECTIVES: The prevalence of obesity is increasing. The aim of this study was to investigate if there is endothelial dysfunction in children with normal or excess weight, and whether the metabolic profile, adipokines, and endothelial dysfunction would be more strongly associated with physical fitness or with physical activity levels. METHOD: Cross-sectional study involving children aged 5-12 years. The evaluation included venous occlusion plethysmography, serum levels of adiponectin, leptin and insulin, lipid profile, physical activity score (PAQ-C questionnaire), and physical fitness evaluation (Yo-Yo test). RESULTS: A total of 62 children participated in this study. Based on the body mass index, 27 were eutrophic, 10 overweight and 25 obese. Triglycerides, LDL cholesterol, HOMA-IR, and leptin were higher in the obese and excess-weight groups compared to the eutrophic group (p<0.01). HDL cholesterol and adiponectin levels were higher in the eutrophic group compared to the obese and excess-weight groups (p<0.01). Flow-mediated vasodilation after hyperemia was higher in the eutrophic group in comparison to obese and excess-weight subjects (p<0.05). There was no difference in the physical activity levels among groups measured by PAQ-C. The Yo-Yo test was significantly associated with HDL cholesterol (rho=-0.41; p=0.01), and this association remained after adjusting for body mass index z-score (rho=0.28; p=0.03). CONCLUSION: This study showed that endothelial dysfunction is already present in obese children, suggesting a predisposition to atherosclerotic disease. Moreover, HDL cholesterol levels were correlated with physical fitness, regardless of body mass index.

Effect of empagliflozin beyond glycemic control: Cardiovascular benefit in patients with type 2 diabetes and established cardiovascular disease. / Efeito da empagliflozina para além do controlo glicémico: benefício cardiovascular em doentes com DMT2 e doença cardiovascular estabelecida.

The prevalence of type 2 diabetes (T2D) continues to increase, and its association with cardiovascular (CV) disease has led to the inclusion of CV endpoints in clinical trials on the treatment of T2D. This article explores the various trials already performed and under development in this field, with particular focus on the EMPA-REG OUTCOME trial. In this trial, empagliflozin, a sodium-glucose co-transporter 2 inhibitor, demonstrated a reduction in CV risk in patients with T2D and established CV disease, in addition to CV safety and a decrease in glycated hemoglobin. This represents a paradigm shift that has led to changes in the international guidelines for the treatment of T2D. These results were maintained in subsequent subgroup analysis for heart failure, chronic kidney disease and peripheral arterial disease, although there are many questions concerning the mechanisms involved in these effects, including whether they are hemodynamic, metabolic or due to decreased myocardial cytoplasmic sodium concentrations. With this reduction in risk for major CV events in patients with T2D, the EMPA-REG OUTCOME trial demonstrated CV protection from a hypoglycemic drug for the first time, and opened a new era in the treatment and management of T2D. This study has led to the development of ongoing trials that will establish which patients will benefit most from this therapy, particularly with regard to comorbidities.

Cardiovascular risk in HIV-infected individuals: A comparison of three risk prediction algorithms.

INTRODUCTION: Cardiovascular (CV) risk is known to be increased in HIV-infected individuals. Our aim was to assess CV risk in HIV-infected adults. METHODS: CV risk was estimated for each patient using three different risk algorithms: SCORE, the Framingham risk score (FRS), and DAD. Patients were classified as at low, moderate or high CV risk. Clinical and anthropometric data were collected. RESULTS: We included 571 HIV-infected individuals, mostly male (67.1%; n=383). Patients were divided into two groups according to antiretroviral therapy (ART): naïve (7.5%; n=43) or under ART (92.5%; n=528). The mean time since HIV diagnosis was 6.7±6.5 years in the naive group and 13.3±6.1 years in the ART group. Metabolic syndrome (MS) was identified in 33.9% (n=179) and 16.3% (n=7) of participants in the ART and naïve groups, respectively. MS was associated with ART (OR=2.7; p=0.018). Triglycerides ≥150 mg/dl (OR=13.643, p<0.001) was one of the major factors contributing to MS. Overall, high CV risk was found in 4.4% (n=23) of patients when the SCORE tool was used, in 20.5% (n=117) using the FRS, and in 10.3% (n=59) using the DAD score. The observed agreement between the FRS and SCORE was 55.4% (k=0.183, p<0.001), between the FRS and DAD 70.5% (k=0.465, p<0.001), and between SCORE and DAD 72.3% (k=0.347, p<0.001). CONCLUSION: On the basis of the three algorithms, we detected a high rate of high CV risk, particularly in patients under ART. The FRS was the algorithm that classified most patients in the high CV risk category (20.5%). In addition, a high prevalence of MS was identified in this patient group.

A pregnant woman with a mechanical prosthetic valve.

A 24-year-old woman who was 11 weeks pregnant and had a mechanical mitral valve presented at the emergency department with ischemic stroke. Although treatment with aspirin and unfractionated heparin was initially successful, subsequent management was almost impossible, as she eventually suffered a right hemispheric stroke, requiring percutaneous intervention and an emergency cesarian; prosthetic valve thrombosis with hemodynamic instability; and multiple bleeding complications. This case demonstrates how difficult it can be to select the appropriate treatment strategy for prosthetic valve thrombosis.

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).

The association between multiple cardiovascular risk factors and overweight in Brazilian adolescents: an analysis based on the grade of membership / A associação entre múltiplos fatores de risco cardiovascular e o excesso de peso em adolescentes brasileiros: uma análise baseada no grade of membership

Abstract The aim of the current research is to analyze the coexistence of modifiable risk behaviors for cardiovascular disease (CVD) in 12-to-17-year-old adolescents living in Brazil and their influence on overweight. National, cross-sectional, school-based epidemiological study focused on estimating the prevalence of cardiovascular risk factors and metabolic syndrome in 12 to 17 year old adolescents enrolled in public and private schools in Brazilian counties accounting for more than 100 thousand inhabitants. The grade of membership method was used to identify the coexistence of risk factors among adolescents. The analytical sample comprised 71,552 adolescents. According to the two herein generated profiles, adolescents classified under Profile 2 have shown behaviors such as smoking, alcohol consumption and diet rich in Ultra-processed food intake ≥ 80% of the percentage of total caloric value. In addition, adolescents presenting CVD risk profile have shown increased likelihood of being overweight. The study has found coexistence of risk factors for CVD in Brazilian adolescents, with emphasis on tobacco smoking and alcoholic beverage intake. In addition, it heads towards the analysis of the association between CVD risk factors and health outcomes, such as overweight.

Estudo epidemiológico nacional, transversal, de base escolar, com foco em estimar a prevalência de fatores de risco cardiovascular e síndrome metabólica em adolescentes de 12 a 17 anos matriculados em escolas públicas e privadas de municípios brasileiros que somam mais de 100 mil habitantes. O grade of membership foi utilizado para identificar a coexistência de fatores de risco entre os adolescentes. A amostra analítica foi composta por 71.552 adolescentes. De acordo com os dois perfis gerados, os adolescentes classificados no Perfil 2 mostraram comportamentos como fumar, consumo de álcool e dieta rica em alimentos ultraprocessados ≥ 80% da porcentagem do valor calórico total. Além disso, adolescentes com perfil de risco para DCV mostraram maior probabilidade de apresentar excesso de peso. O estudo encontrou coexistência de fatores de risco para DCV em adolescentes brasileiros, com destaque para tabagismo e consumo de bebidas alcoólicas. Além disso, demonstra associação entre fatores de risco para DCV e desfechos de saúde, como o excesso de peso.

Cardiovascular Risk Factors in Premature Ovarian Insufficiency using Hormonal Therapy / Fatores de risco cardiovascular na insuficiência ovariana prematura em uso de terapia hormonal

Abstract Objective Premature ovarian insufficiency (POI) is characterized by early hypoestrogenism. An increased risk of cardiovascular (CV) disease is a long-term consequence of POI. A challenge of hormone therapy (HT) is to reduce the CV risk. Methods Cross-sectional study with lipid profile analysis (total cholesterol, LDL-C, HDL-C, VLDL-C and triglycerides), blood glucose levels and arterial blood pressure of women with POI using HT, compared with age and BMI-matched women with normal ovarian function (controls). Results The mean age and BMI of 102 POI patients using HT and 102 controls were 37.2 ± 6.0 and 37.3 ± 5.9 years, respectively; 27.0 ± 5.2 and 27.1 ± 5.4 kg/m2. There wasn't difference between groups in arterial systolic and diastolic blood pressure, blood glucose levels, total cholesterol, LDL-C, VLDL-C and triglycerides. HDL-C levels were significantly higher in the POI group (56.3 ± 14.6 and 52 ± 13.9mg/dL; p = 0.03). Arterial hypertension was the most prevalent chronic disease (12% in the POI group, 19% in the control group, p = ns), followed by dyslipidemia (6 and 5%, in POI and control women). Conclusion Women with POI using HT have blood pressure levels, lipid and glycemic profile and prevalence of hypertension and dyslipidemia similar to women of the same age and BMI with preserved gonadal function, in addition to better HDL levels.

Resumo Objetivo A insuficiência ovariana prematura (IOP) é caracterizada pelo hipoestrogenismo precoce. Risco aumentado de doença cardiovascular (CV) é uma consequência a longo prazo da IOP e um desafio da terapia hormonal (TH) é reduzir o risco CV. Métodos Estudo transversal com análise do perfil lipídico (colesterol total, LDL-C, HDL-C, VLDL-C e triglicerídeos), glicemia e pressão arterial de mulheres com IOP em uso de TH, em comparação a mulheres com função ovariana normal (controles) pareadas por idade e IMC. Resultados A média de idade e IMC de 102 pacientes com IOP em uso de TH e 102 controles foi de 37,2 ± 6,0 e 37,3 ± 5,9 anos, respectivamente; 27,0 ± 5,2 e 27,1 ± 5,4 kg/m2. Não houve diferença entre os grupos na pressão arterial sistólica e diastólica, glicemia, colesterol total, LDL-C, VLDL-C e triglicerídeos. Os níveis de HDL-C foram significativamente maiores no grupo IOP (56,3 ± 14,6 e 52 ± 13,9mg/dL; p = 0,03). A hipertensão arterial foi a doença crônica mais prevalente (12% no grupo POI, 19% no grupo controle, p = ns), seguida da dislipidemia (6 e 5%, no grupo POI e controle). Conclusão Mulheres com IOP em uso de TH apresentam níveis pressóricos, perfil lipídico e glicêmico e prevalência de hipertensão e dislipidemia semelhantes às mulheres da mesma idade e IMC com função gonadal preservada, além de melhores níveis de HDL.

Dieta mediterrânea para prevenção de doenças cardiovasculares: overview de revisões sistemáticas / Mediterranean diet for prevention of cardiovascular diseases: overview of systematic reviews

Contextualização: As doenças cardiovasculares (DCV) representam a principal causa de morte no Brasil e no mundo e a dieta mediterrânea (DM) surgiu como possibilidade de prevenção dessas doenças. Ela envolve o alto consumo de frutas, vegetais, frutos do mar, nozes, legumes, grãos e azeite, e ingestão moderada de vinho nas refeições, além de menor ingestão de carnes vermelhas e processadas, gordura saturada, doces e bebidas açucaradas. Objetivo: Avaliar a efetividade da DM para prevenção de DCV. Métodos: Trata-se de overview de revisões sistemáticas. Procedeu-se à busca por estudos que associavam a DM às DCV em quatro bases eletrônicas de dados: Cochrane - Central de Registros de Ensaios Clínicos - CENTRAL (2023), PubMed (1966-2023), Portal BVS (1982-2023) e EMBASE (1974-2023). Dois pesquisadores, independentemente extraíram os dados e avaliaram a qualidade dos estudos para a síntese. O desfecho primário de análise envolveu a prevenção de doença cardiovascular e a redução de mortalidade. Resultados: 5 revisões sistemáticas foram incluídas, totalizando 74 ensaios clínicos (n = 124.820) e 16 coortes prospectivas (n = 722.495). Discussão: Embora os estudos incluídos relatem benefícios favoráveis à DM para prevenção de DCV, as evidências são de baixa a moderada qualidade, diante da heterogeneidade e fragilidades metodológicas. Sugere-se a realização de novos estudos clínicos com padronização de relato dos resultados. Conclusão: Parece haver benefício da DM para prevenção de DCV, mas diante das evidências limitadas, há incertezas que tornam lícita a recomendação por novos ensaios clínicos com comparação a outras dietas, para maior robustez dos achados.
