RESUMO

Heart failure (HF) is a complex clinical syndrome, associated with high rates of mortality, hospitalization, and impairment of quality of life. Obesity and type 2 diabetes are major cardiometabolic drivers, represented as distinct stages of adiposity- and dysglycemia-based chronic disease (ABCD, DBCD), respectively, and leading to cardiometabolic-based chronic disease (CMBCD). This review focuses on one aspect of the CMBCD model: how ABCD and DBCD influence genesis and progression of HF phenotypes. Specifically, the relationships of ABCD and DBCD stages with structural and functional heart disease, HF risk, and outcomes in overt HF are detailed. Also, evidence-based lifestyle, pharmacological, and procedural interventions that promote or reverse cardiac remodeling and outcomes in individuals at risk or with HF are discussed. In summary, driver-based chronic disease models for individuals at risk or with HF can expose prevention targets for more comprehensive interventions to improve clinical outcomes. Future randomized trials that investigate structured lifestyle, pharmacological, and procedural therapies specifically tailored for the CMBCD model are needed to develop personalized care plans to decrease HF susceptibility and improve outcomes.

RESUMO

BACKGROUND: Chemotherapy with doxorubicin may lead to left ventricular dysfunction. There is a controversial recommendation that biomarkers can predict ventricular dysfunction, which is one of the most feared manifestations of anthracycline cardiotoxicity. OBJECTIVE: The aim of this study was to evaluate the behavior of biomarkers such as Troponin I, type B natriuretic peptide, creatine phosphokinase fraction MB, and myoglobin in predicting cardiotoxicity in a cohort of women with breast cancer undergoing chemotherapy with anthracycline. METHODS: This is an observational, prospective, longitudinal, unicentric study, which included 40 women with breast cancer, whose therapeutic proposal included treatment with doxorubicin. The protocol had a clinical follow-up of 12 months. Biomarkers such as Troponin I, type B natriuretic peptide, creatine phosphokinase fraction MB, and myoglobin were measured pre-chemotherapy and after the first, third, fourth, and sixth cycles of chemotherapy. RESULTS: There was a progressive increase in type B natriuretic peptide and myoglobin values in all chemotherapy cycles. Although creatine phosphokinase fraction MB showed a sustained increase, this increase was not statistically significant. Troponin, type B natriuretic peptide, myoglobin, and creatine phosphokinase fraction MB were the cardiotoxicity markers with the earliest changes, with a significant increase after the first chemotherapy session. However, they were not able to predict cardiotoxicity. CONCLUSION: Troponin I, type B natriuretic peptide, myoglobin, and creatine phosphokinase fraction MB are elevated during chemotherapy with doxorubicin, but they were not able to predict cardiotoxicity according to established clinical and echocardiographic criteria. The incidence of subclinical cardiotoxicity resulting from the administration of doxorubicin was 12.5%.

RESUMO

Background: Driver-based chronic disease models address the public health challenge of cardiometabolic risk. However, there is no data available about the novel Hypertension-Based Chronic Disease (HBCD) model. This study investigates the prevalence, characteristics, and prognostic significance of HBCD Stages in a primary care cohort. Methods: This study included participants aged ≥45 years, randomly selected from the primary care program of a Brazilian medium-sized city. Participants underwent electrocardiogram, tissue Doppler echocardiogram and were followed for a median of 6 years. Participants were classified into HBCD Stages as follows: Stage 1: hypertension risk factors; Stage 2: pre-hypertension; Stage 3: hypertension; and Stage 4: hypertension complications. Results: Overall, 633 participants were included in the cross-sectional analysis and 560 that had follow-up data were included in the prognostic analysis. From 633 participants, 1.3% had no identifiable risk factors for HBCD, 10.0% were Stage 1, 14.7% Stage 2, 51.5% Stage 3, and 22.5% Stage 4. Increasing HBCD stages had worse glomerular filtration rates, echocardiographic markers, and higher body mass index, waist circumference, blood glucose levels, and prevalence of type 2 diabetes. Rates of all-cause mortality or cardiovascular hospitalization increased across HBCD Stages: Stage 1: 3.6%; Stage 2: 4.8%, Stage 3: 7.6%; and Stage 4: 39.5%. Kaplan-Meier curves showed composite outcome worsened across HBCD Stages 1-4 (p < 0.001). Conclusions: HBCD is a conceptually and prognostically valid model. Remarkably, HBCD stages were associated with progressively worsening markers of heart disease, declining kidney function and higher rates of all-cause mortality or cardiovascular hospitalization.

RESUMO

Approximately 300 million non-cardiac surgeries are performed annually worldwide and adverse cardiovascular events are the main cause of morbidity and mortality in the peri- and postoperative period. Myocardial injury after non-cardiac surgery (MINS) is a new clinical entity associated with adverse cardiovascular outcomes. MINS is defined as myocardial injury that can result in necrosis due to ischemia, marked by increase in biomarker levels. It has prognostic relevance and occurs within up to 30 days after non-cardiac surgery. The diagnostic criteria for MINS are an elevated postoperative measure of troponin judged as secondary to myocardial ischemia, i.e., with no evidence of a non-ischemic etiology, during or within 30 days after non-cardiac surgery, and without the requirement of an ischemic symptom or electrocardiographic finding of ischemia. Recently, patients at higher risk for MINS have been recognized using clinical variables and biomarkers and established protocols for greater surveillance in relation to electrocardiographic monitoring and cardiac troponin dosage. Elderly patients with previous atherosclerotic disease need to measure troponin daily in the postoperative period. The aim of the present work is to describe this new public health problem, its clinical impact and contemporary therapeutic approach.


Aproximadamente 300 milhões de cirurgias não cardíacas são realizadas anualmente no mundo, e eventos cardiovasculares adversos são as principais causas de morbimortalidade no período perioperatório e pós-operatório. A lesão miocárdica após cirurgia não cardíaca (MINS, do inglês myocardial injury after non-cardiac surgery) é uma nova entidade clínica associada com desfechos cardiovasculares adversos. MINS é definida como uma lesão miocárdica que pode resultar em necrose secundária à isquemia, com elevação dos biomarcadores. A lesão tem importância prognóstica e ocorre em até 30 dias após a cirurgia não cardíaca. Os critérios diagnósticos para MINS são: níveis elevados de troponina durante ou em até 30 dias após a cirurgia não cardíaca, sem evidência de etiologia não isquêmica, sem que haja necessariamente sintomas isquêmicos ou achados eletrocardiográficos de isquemia. Recentemente, pacientes com maior risco para MINS têm sido identificados por variáveis clínicas e biomarcadores, bem como por protocolos de vigilância quanto ao monitoramento eletrocardiográfico e dosagem de troponina cardíaca. Pacientes idosos com doença aterosclerótica prévia necessitam medir troponina diariamente no período pós-operatório. O objetivo deste trabalho é descrever este novo problema de saúde pública, seu impacto clínico e a abordagem terapêutica contemporânea.

RESUMO

INTRODUCTION: Population aging is associated with increased prevalence of cardiovascular diseases that have a significant impact on overall morbidity and mortality. Insulin resistance (IR) and visceral obesity are risk factors for vascular damage and cardiometabolic diseases. AIMS: Estimating the correlation between lipid accumulation product (LAP) and IR in elderly individuals and comparing them to traditional anthropometric indices. METHODS: Cross-sectional study comprising 411 individuals >60 years, who were treated in a primary care service. Body mass index (BMI), neck circumference (NC), waist circumference (WC), hip circumference (HC), arm circumference (AC), sagittal abdominal diameter (SAD) and waist-hip ratio (WHR) were recorded. IR was estimated based on HOMA-IR (homeostasis model assessment IR index). LAPa index was calculated as [WC-65]×[triglyceride (TG)] in men, and as [WC-58]×[TG] in women, whereas LAPb was calculated by using the minimum WC values recorded for the current sample, i.e., 61.5 cm for women and 71.5 cm for men. RESULTS: There was correlation among LAPa (0.506), LAPb (0.515) and HOMA-IR. LAP was better correlated to HOMA-IR and showed higher area under the curve than BMI, NC, WHR and SAD. Based on the receiver operating characteristic curve analysis, LAPb≥47.40 and LAPa≥52.5 were the best cut-off values used to identify individuals with IR presenting 68.8% and 68.2% sensitivity, and 68.6% and 68.6% specificity, respectively. CONCLUSION: LAP may be a useful and simple clinical marker to assess cardiometabolic risk factors in the elderly population treated at a primary care service.

RESUMO

BACKGROUND: The classification of heart failure (HF) by phenotypes has a great relevance in clinical practice. OBJECTIVE: The study aimed to analyze the prevalence, clinical characteristics, and outcomes between HF phenotypes in the primary care setting. METHODS: This is an analysis of a cohort study including 560 individuals, aged ≥ 45 years, who were randomly selected in a primary care program. All participants underwent clinical evaluations, b-type natriuretic peptide (BNP) measurements, electrocardiogram, and echocardiography in a single day. HF with left ventricular ejection fraction (LVEF) < 40% was classified as HF with reduced ejection fraction (HFrEF), LVEF 40% to 49% as HF with mid-range ejection fraction (HFmrEF) and LVEF ≥ 50% as HF with preserved ejection fraction (HFpEF). After 5 years, the patients were reassessed as to the occurrence of the composite outcome of death from any cause or hospitalization for cardiovascular disease. RESULTS: Of the 560 patients included, 51 patients had HF (9.1%), 11 of whom had HFrEF (21.6%), 10 had HFmrEF (19.6%) and 30 had HFpEF (58.8%). HFmrEF was similar to HFpEF in BNP levels (p < 0.001), left ventricular mass index (p = 0.037), and left atrial volume index (p < 0.001). The HFmrEF phenotype was similar to HFrEF regarding coronary artery disease (p = 0.009). After 5 years, patients with HFmrEF had a better prognosis when compared to patients with HFpEF and HFrEF (p < 0.001). CONCLUSION: The prevalence of ICFEI was similar to that observed in previous studies. ICFEI presented characteristics similar to ICFEP in this study. Our data show that ICFEi had a better prognosis compared to the other two phenotypes.


FUNDAMENTO: A classificação da insuficiência cardíaca (IC) por fenótipos possui grande relevância na prática clínica. OBJETIVO: O estudo visou analisar a prevalência, as características clínicas e os desfechos entre os fenótipos de IC no contexto da atenção primária. MÉTODOS: Trata-se de uma análise de um estudo de coorte que incluiu 560 indivíduos, com idade ≥ 45 anos, que foram selecionados aleatoriamente em um programa de atenção primária. Todos os participantes foram submetidos a avaliações clínicas, dosagem do peptídeo natriurético tipo B (BNP), eletrocardiograma e ecocardiografia em um único dia. A IC com fração de ejeção do ventrículo esquerdo (FEVE) < 40% foi classificado como IC com fração de ejeção reduzida (ICFEr), FEVE de 40% a 49% como IC com fração de ejeção intermediária (ICFEi) e FEVE ≥ 50% como IC com fração de ejeção preservada (ICFEp). Após 5 anos, os pacientes foram reavaliados quanto à ocorrência do desfecho composto de óbito por qualquer causa ou internação por doença cardiovascular. RESULTADOS: Dos 560 pacientes incluídos, 51 pacientes tinham IC (9,1%), 11 dos quais tinham ICFEr (21,6%), 10 tinham ICFEi (19,6%) e 30 tinham ICFEp (58,8%). A ICFEi foi semelhante à ICFEp nos níveis de BNP (p < 0,001), índice de massa do ventrículo esquerdo (p = 0,037) e índice de volume do átrio esquerdo (p < 0,001). O fenótipo de ICFEi foi semelhante ao de ICFEr em relação à doença arterial coronariana (p = 0,009). Após 5 anos, os pacientes com ICFEi apresentaram melhor prognóstico quando comparados aos pacientes com ICFEp e ICFEr (p < 0,001). CONCLUSÃO: A prevalência de ICFEI foi semelhante ao observado em estudos anteriores. A ICFEI apresentou características semelhantes a ICFEP neste estudo. Nossos dados mostram que a ICFEi teve melhor prognóstico em comparação com os outros dois fenótipos.

RESUMO

BACKGROUND: In many cities around the world, the mortality rate from cancer (CA) has exceeded that from disease of the circulatory system (DCS). OBJECTIVES: To compare the mortality curves from DCS and CA in the most populous capital cities of the five regions of Brazil. METHODS: Data of mortality rates from DCS and CA between 2000 and 2015 were collected from the Mortality Information System of Manaus, Salvador, Goiania, Sao Paulo and Curitiba, and categorized by age range into early (30-69 years) and late (≥ 70 years), and by gender of the individuals. Chapters II and IX of the International Classification of Diseases-10 were used for the analysis of causes of deaths. The Joinpoint regression model was used to assess the tendency of the estimated annual percentage change of mortality rate, and the Monte Carlo permutation test was used to detect when changes occurred. Statistical significance was set at 5%. RESULTS: There was a consistent decrease in early and late mortality from DCS in both genders in the cities studied, except for late mortality in men in Manaus. There was a tendency of decrease of mortality rates from CA in São Paulo and Curitiba, and of increase in the rates from CA in Goiania. In Salvador, there was a decrease in early mortality from CA in men and women and an increase in late mortality in both genders. CONCLUSION: There was a progressive and marked decrease in the mortality rate from DCS and a maintenance or slight increase in CA mortality in the five capital cities studied. These phenomena may lead to the intersection of the curves, with predominance of mortality from CA (old and new cases).

RESUMO

BACKGROUND: Left ventricular remodeling (LVR) is related to both non-fatal and fatal outcomes. OBJECTIVE: To describe the geometric patterns of the LV and their associations. METHODS: A total of 636 individuals between the ages of 45 and 99 years in Rio de Janeiro, Brazil, were submitted to clinical evaluation, laboratory tests, electrocardiogram, and tissue Doppler echocardiography (TDE). The difference between categories was tested with Kruskall-Wallis with post hoc tests, once all variables studied are non-normally distributed and Pearson's Qui-square (categorical variables). Gross and adjusted ORs were estimated by logistic regression. The level of significance was 5% for all tests. Subjects had LVR characterized as: normal geometry (NG), concentric remodeling (CR), concentric hypertrophy (CH), and eccentric hypertrophy (EH). RESULTS: The prevalence of altered patterns was 33%. Subjects presented NG (n = 423; 67%); EH (n = 186; 29%); CH (n = 14; 2%); and CR (n = 13; 2%). The variables of gender, age, level of education and albumin/creatinine ratio (A/C), showed a relationship with the chance of EH even after adjustment. CONCLUSION: Approximately one third of the studied individuals had LVR and were at risk for developing heart failure. Altered A/C in urine was associated with EH, indicating an early relationship between cardiac and renal dysfunction.

RESUMO

The absence of a consensus about the diagnostic criteria for acute cardiorenal syndrome (ACRS) affects its prognosis. This study aimed at assessing the diagnostic criteria for ACRS and their impact on prognosis. A systematic review was conducted using PRISMA methodology and PICO criteria in the MEDLINE, EMBASE and LILACS databases. The search included original publications, such as clinical trials, cohort studies, case-control studies, and meta-analyses, issued from January 1998 to June 2018. Neither literature nor heart failure guidelines provided a clear definition of the diagnostic criteria for ACRS. The serum creatinine increase by at least 0.3 mg/dL from baseline creatinine is the most used diagnostic criterion. However, the definition of baseline creatinine, as well as which serum creatinine should be used as reference for critical patients, is still controversial. This systematic review suggests that ACRS criteria should be revised to include the diagnosis of ACRS on hospital admission. Reference serum creatinine should reflect baseline renal function before the beginning of acute kidney injury.

RESUMO

BACKGROUND: Longevity, combined with a higher prevalence of obesity, particularly visceral obesity, has been associated with an increased risk of cardiovascular diseases. Insulin resistance (IR) is an important link between visceral obesity and cardiovascular diseases. An important association has been found between sagittal abdominal diameter, visceral obesity and IR. The objective of this study is to evaluate sagittal abdominal diameter as a marker of visceral obesity and correlate it with IR in older primary health care patients. METHODS: A cross-sectional study was performed with 389 patients over 60 years of age (70.6 ± 6.9), of whom 74% were female. Their clinical, anthropometric and metabolic profiles were assessed and their fasting serum insulin level was used to calculate the homeostasis model assessment insulin resistance (HOMA-IR). Sagittal abdominal diameter was measured in the supine position at the midpoint between the iliac crest and the last rib with abdominal calipers. RESULTS: Sagittal abdominal diameter was significantly correlated with anthropometric measures of general and visceral obesity and with HOMA-IR in both genders. There was no change in the association between sagittal abdominal diameter and HOMA-IR after adjusting for age, sex, diabetes and hypertension. CONCLUSION: It is feasible to use sagittal abdominal diameter in older primary care patients as a tool to evaluate visceral obesity, which is an indicator of cardiovascular risk.

RESUMO

Breast cancer is the most frequently diagnosed tumor in women worldwide, with a significant impact on morbidity and mortality. Chemotherapy and hormone therapy have significantly reduced mortality; however, the adverse effects are significant. Aspirin has been incorporated into clinical practice for over 100 years at a low cost, making it particularly attractive as a potential agent in breast cancer prevention and as an adjunct treatment to endocrine therapy in the prophylaxis of cardiovascular complications. The objective of this study was to evaluate the role of aspirin in reducing the incidence of breast cancer and to evaluate the impact of its use on morbidity and mortality and reduction of cardiovascular events as adjuvant therapy during breast cancer treatment with selective estrogen receptor modulators. A systematic review was performed using the PRISMA methodology and PICO criteria, based on the MEDLINE, EMBASE and LILACS databases. The original articles of clinical trials, cohort, case-control studies and meta-analyses published from January 1998 to June 2017, were considered. Most studies showed an association between the use of selective estrogen receptor modulators and the increase in thromboembolic events. The studies suggest a protective effect of aspirin for cardiovascular events during its concomitant use with selective estrogen receptor modulators and in the prevention of breast cancer. This systematic review suggests that aspirin therapy combines the benefit of protection against cardiovascular events with the potential reduction in breast cancer risk, and that the evaluation of the benefits of the interaction of endocrine therapy with aspirin should be further investigated.

RESUMO

Heart failure with preserved ejection fraction (HFpEF) is now an emerging cardiovascular epidemic, being identified as the main phenotype observed in clinical practice. It is more associated with female gender, advanced age and comorbidities such as hypertension, diabetes, obesity and chronic kidney disease. Amyloidosis is a clinical disorder characterized by the deposition of aggregates of insoluble fibrils originating from proteins that exhibit anomalous folding. Recently, pictures of senile amyloidosis have been described in patients with HFpEF, demonstrating the need for clinical cardiologists to investigate this etiology in suspect cases. The clinical suspicion of amyloidosis should be increased in cases of HFPS where the cardio imaging methods are compatible with infiltrative cardiomyopathy. Advances in cardio imaging methods combined with the possibility of performing genetic tests and identification of the type of amyloid material allow the diagnosis to be made. The management of the diagnosed patients can be done in partnership with centers specialized in the study of amyloidosis, which, together with the new technologies, investigate the possibility of organ or bone marrow transplantation and also the involvement of patients in clinical studies that evaluate the action of the new emerging drugs. Resumo A insuficiência cardíaca com fração de ejeção preservada (ICFEP) é hoje uma epidemia cardiovascular emergente, sendo identificada como o principal fenótipo observado na prática clínica. Está mais associado ao sexo feminino, idade avançada e a comorbidades como hipertensão arterial, diabetes, obesidade e doença renal crônica. A amiloidose é uma desordem clínica caracterizada pelo depósito de agregados de fibrilas insolúveis originadas de proteínas que apresentam dobramento anômalo. Recentemente, têm sido descritos quadros de amiloidose senil em pacientes com ICFEP, demonstrando a necessidade de os cardiologistas clínicos investigarem esta etiologia em casos suspeitos. Deve-se aumentar a suspeição clínica de amiloidose diante dos casos de ICFEP onde os métodos de cardioimagem sejam compatíveis com o quadro de cardiomiopatia infiltrativa. Os avanços nos métodos de cardioimagem aliados à possibilidade de realização de testes genéticos e identificação do tipo do material amiloide permitem a realização do diagnóstico. O manejo dos pacientes diagnosticados pode ser feito em parceria com centros especializados no estudo de amiloidose, que, aliados às novas tecnologias, investigam a possibilidade de transplante de órgãos ou medula óssea e também o envolvimento dos pacientes em estudos clínicos que avaliam a ação das novas drogas emergentes.

RESUMO

INTRODUCTION: Cardiovascular disease (CVD) is especially prevalent in patients with chronic kidney disease (CKD). OBJECTIVE: To evaluate the role of CKD and metabolic syndrome (MS), which is a cluster of risk factors for CVD, as predictors of CVD. METHODS: Observational, cross-sectional study with a random sample aged 45 or more years extracted from the population assisted by the primary care program in Niterói city in the state of Rio de Janeiro, Brazil. CKD was diagnosed by the K/DOQI guidelines and MS, by the harmonized criteria. CVD was said to be present if the participant had one or more of the following findings: echocardiographic abnormalities, and history of myocardial infarction, stroke or heart failure. A logistic regression model was developed to analyze risk factors for CVD using CKD as the variable of primary interest. RESULTS: Fifty hundred and eighty-one participants (38.2% male) with a mean age of 59.4 ± 10.2 years were analyzed. The prevalence rate of CKD was 27.9%. In participants without CKD, MS was associated with a slight but statistically significant increase in the risk for CVD (OR = 1.52, p = 0.037); in those with CKD but without MS the risk for CVD was also statistically significant and at a greater magnitude (OR = 2.42, p = 0.003); when both were present the risk for CVD was substantially higher (OR = 5.13, p < 0.001). CONCLUSION: In this study involving a population assisted by a primary care program, CKD was confirmed as an independent risk factor for CVD. The presence of MS concurrent with CKD substantially amplified the risk for CVD.

RESUMO

BACKGROUND:: Hypertension is the most prevalent risk factor for cardiovascular disease, and its proper control can prevent the high morbidity and mortality associated with this disease. OBJECTIVE:: To assess the degree of compliance of antihypertensive prescriptions with the VI Brazilian Guidelines on Hypertension and the blood pressure control rate in primary care. METHODS:: Cross-sectional study conducted between August 2011 and November 2012, including 332 adults ≥ 45 years registered in the Family Doctor Program in Niteroi and selected randomly. The analysis included the prescribed antihypertensive classes, doses, and frequencies, as well as the blood pressure (BP) of the individuals. RESULTS:: The rate of prescription compliance was 80%. Diuretics were the most prescribed medications, and dual therapy was the most used treatment. The most common non-compliances were underdosing and underfrequencies. The BP goal in all cases was < 140/90 mmHg, except for diabetic patients, in whom the goal was set at < 130/80 mmHg. Control rates according to these goals were 44.9% and 38.6%, respectively. There was no correlation between prescription compliance and BP control. CONCLUSIONS:: The degree of compliance was considered satisfactory. The achievement of the targets was consistent with national and international studies, suggesting that the family health model is effective in BP management, although it still needs improvement. FUNDAMENTO:: A hipertensão arterial é o fator de risco mais prevalente para a doença cardiovascular e seu controle adequado pode prevenir a elevada morbi-mortalidade associada a esta doença. OBJETIVO:: Avaliar o grau de conformidade das prescrições de anti-hipertensivos com as VI Diretrizes Brasileiras de Hipertensão e a taxa de controle pressórico na atenção básica. MÉTODOS:: Estudo transversal conduzido entre agosto de 2011 e novembro de 2012, incluindo 332 adultos ≥ 45 anos cadastrados no Programa Médico de Família de Niterói e selecionados aleatoriamente. Foram analisadas as classes de anti-hipertensivos prescritos, suas doses e frequências, bem como a pressão arterial (PA) dos indivíduos. RESULTADOS:: A taxa de conformidade das prescrições foi de 80%. Diuréticos foram as medicações mais prescritas e a terapia dupla foi o tratamento mais utilizado. As não conformidades mais comuns foram subdoses e subfrequências. A meta de PA para todos os casos foi < 140/90 mmHg, exceto para diabéticos, que foi < 130/80 mmHg. As taxas de controle de acordo com essas metas foram de 44,9% e 38,6%, respectivamente. Não houve correlação entre conformidade da prescrição e controle pressórico. CONCLUSÕES:: O grau de conformidade foi considerado satisfatório. O alcance das metas foi compatível com estudos nacionais e internacionais, sugerindo que o modelo de saúde da família é efetivo no manejo da PA, embora ainda necessite aprimoramento.

RESUMO

BACKGROUND: Heart failure (HF) is a major public health issue with implications on health-related quality of life (HRQL). OBJECTIVE: To compare HRQL, estimated by the Short-Form Health Survey (SF-36), in patients with and without HF in the community. METHODS: Cross-sectional study including 633 consecutive individuals aged 45 years or older, registered in primary care. The subjects were selected from a random sample representative of the population studied. They were divided into two groups: group I, HF patients (n = 59); and group II, patients without HF (n = 574). The HF group was divided into HF with preserved ejection fraction (HFpEF - n = 35) and HF with reduced ejection fraction (HFrEF - n = 24). RESULTS: Patients without HF had a mean SF-36 score significantly greater than those with HF (499.8 ± 139.1 vs 445.4 ± 123.8; p = 0.008). Functional capacity - ability and difficulty to perform common activities of everyday life - was significantly worse (p < 0.0001) in patients with HF independently of sex and age. There was no difference between HFpEF and HFrEF. CONCLUSION: Patients with HF had low quality of life regardless of the syndrome presentation (HFpEF or HFrEF phenotype). Quality of life evaluation in primary care could help identify patients who would benefit from a proactive care program with more emphasis on multidisciplinary and social support.

RESUMO

Resumo Aproximadamente 300 milhões de cirurgias não cardíacas são realizadas anualmente no mundo, e eventos cardiovasculares adversos são as principais causas de morbimortalidade no período perioperatório e pós-operatório. A lesão miocárdica após cirurgia não cardíaca (MINS, do inglês myocardial injury after non-cardiac surgery) é uma nova entidade clínica associada com desfechos cardiovasculares adversos. MINS é definida como uma lesão miocárdica que pode resultar em necrose secundária à isquemia, com elevação dos biomarcadores. A lesão tem importância prognóstica e ocorre em até 30 dias após a cirurgia não cardíaca. Os critérios diagnósticos para MINS são: níveis elevados de troponina durante ou em até 30 dias após a cirurgia não cardíaca, sem evidência de etiologia não isquêmica, sem que haja necessariamente sintomas isquêmicos ou achados eletrocardiográficos de isquemia. Recentemente, pacientes com maior risco para MINS têm sido identificados por variáveis clínicas e biomarcadores, bem como por protocolos de vigilância quanto ao monitoramento eletrocardiográfico e dosagem de troponina cardíaca. Pacientes idosos com doença aterosclerótica prévia necessitam medir troponina diariamente no período pós-operatório. O objetivo deste trabalho é descrever este novo problema de saúde pública, seu impacto clínico e a abordagem terapêutica contemporânea.


Abstract Approximately 300 million non-cardiac surgeries are performed annually worldwide and adverse cardiovascular events are the main cause of morbidity and mortality in the peri- and postoperative period. Myocardial injury after non-cardiac surgery (MINS) is a new clinical entity associated with adverse cardiovascular outcomes. MINS is defined as myocardial injury that can result in necrosis due to ischemia, marked by increase in biomarker levels. It has prognostic relevance and occurs within up to 30 days after non-cardiac surgery. The diagnostic criteria for MINS are an elevated postoperative measure of troponin judged as secondary to myocardial ischemia, i.e., with no evidence of a non-ischemic etiology, during or within 30 days after non-cardiac surgery, and without the requirement of an ischemic symptom or electrocardiographic finding of ischemia. Recently, patients at higher risk for MINS have been recognized using clinical variables and biomarkers and established protocols for greater surveillance in relation to electrocardiographic monitoring and cardiac troponin dosage. Elderly patients with previous atherosclerotic disease need to measure troponin daily in the postoperative period. The aim of the present work is to describe this new public health problem, its clinical impact and contemporary therapeutic approach.

RESUMO

BACKGROUND: Obstructive sleep apnea syndrome (OSAS) is a chronic, progressive disease with high morbidity and mortality. It is underdiagnosed, especially among women. OBJECTIVE: To study the prevalence of high risk for OSAS globally and for the Berlin Questionnaire (BQ) categories, and to evaluate the reliability of the BQ use in the population studied. METHODS: Observational, cross-sectional study with individuals from the Niterói Family Doctor Program, randomly selected, aged between 45 and 99 years. The visits occurred between August/2011 and December/2012. Variables associated with each BQ category and with high risk for OSAS (global) were included in logistic regression models (p < 0.05). RESULTS: Of the total (616), 403 individuals (65.4%) reported snoring. The prevalence of high risk for OSA was 42.4%, being 49.7% for category I, 10.2% for category II and 77.6% for category III. CONCLUSION: BQ showed an acceptable reliability after excluding the questions Has anyone noticed that you stop breathing during your sleep? and Have you ever dozed off or fallen asleep while driving?. This should be tested in further studies with samples mostly comprised of women and low educational level individuals. Given the burden of OSAS-related diseases and risks, studies should be conducted to validate new tools and to adapt BQ to better screen OSAS.
