Resumo 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. Abstract 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.

Introduction: The development of clinical reasoning to diagnose diseases and order ancillary tests, such as radiology imaging, is based on history-taking and physical examination skills, which are developed during the semiology course. Objective: We aimed to evaluate the results of the innovative integration of two courses in the medical curriculum at our institution: Medical Semiology and Clinical Radiology. Methods: The sample consisted of 184 fifth-semester medical students attending the two courses simultaneously. Extra-class semiology-radiology sessions based on theoretical and practical topics integrating radiological images and semiological signs were conducted, and the results were assessed by applying a semi-structured questionnaire to the participants, in which all 18 items were rated on a scale from 0 (worst) to 10 (best). The normality hypothesis in score distribution was verified by the Kolmogorov-Smirnov test and the Shapiro-Wilk test. The distribution of the 18 scores were summarized by descriptive statistics and compared by Friedman’s test, with post-hoc test in pairwise comparisons adjusted by Bonferroni test. Correlations between the scores were determined by Spearman’s Rank Correlation Coefficients. Results: The overall mean score for the semiology-radiology sessions was high (8.55). Students were satisfied with the selection of clinical cases (8.46) and found that the semiology-radiology sessions contributed to the development of their clinical reasoning (8.58). Conclusion: Medical schools are facing new challenges in medical education. The innovative concept of Radiology-Semiology integrated teaching modality affects the students’ self-perception ability to interpret radiological images and might be an educational strategy trend. Resumo: Introdução: O desenvolvimento do raciocínio clínico para diagnosticar doenças e solicitar exames complementares, como os radiológicos, baseia-se na história e no exame físico, desenvolvidos durante o curso de Semiologia. Objetivo: Nosso objetivo foi avaliar os resultados da integração inovadora de duas disciplinas no currículo médico em nossa instituição: Semiologia Médica e Radiologia Clínica. Métodos: A amostra foi composta por 184 estudantes de Medicina do quinto semestre que participaram das duas disciplinas simultaneamente. Realizaram-se sessões extraclasse de semiologia e radiologia, baseadas em tópicos teóricos e práticos, integrando imagens radiológicas com sinais semiológicos. Avaliaram-se os resultados por meio da aplicação de um questionário semiestruturado aos participantes, no qual todos os 18 itens foram classificados em uma escala de 0 (pior) a 10 (melhor). A hipótese de normalidade na distribuição dos escores foi verificada pelos testes de Kolmorov-Smirnov e Shapiro-Wilk. As 18 distribuições de pontuação foram resumidas por estatística descritiva e comparadas pelo teste de Friedman, com teste post hoc em comparações pareadas ajustadas por Bonferroni. As correlações entre as pontuações foram determinadas pelos coeficientes de correlação de classificação de Spearman. Resultados: O escore médio geral para as sessões de semiologia e radiologia foi alto (8,55). Os estudantes ficaram satisfeitos com a seleção de casos clínicos (8,46) e descobriram que as sessões de semiologia-radiologia contribuíram para o desenvolvimento de seu raciocínio clínico (8,58). Conclusão: As escolas médicas enfrentam novos desafios na educação médica. O conceito inovador da modalidade de ensino integrado de radiologia-semiologia afeta a capacidade de autopercepção dos alunos para interpretar imagens radiológicas e pode ser uma tendência de estratégia educacional.

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: Introdução: O envelhecimento da população associa-se ao aumento da prevalência de doenças cardiovasculares, com um impacto significativo na morbimortalidade geral. Resistência à insulina (RI) e obesidade visceral são fatores de risco para lesão vascular e doença cardiometabólica. Objetivo: Estimar a correlação entre produto de acumulação de lípidos (LAP) e IR em indivíduos idosos e compará-los com os índices antropométricos tradicionais. Métodos: Este estudo transversal incluiu 411 indivíduos acima de 60 anos, atendidos na atenção primária. Foram registradas índice de massa corporal (IMC), circunferência do pescoço (CP), circunferência da cintura (CC), circunferência do quadril (CQ), circunferência do braço (CA), diâmetro abdominal sagital (DAS) e relação cintura-quadril (RCQ). A RI foi estimada pelo HOMA-IR (índice de avaliação do modelo de homeostase). O índice de PALa foi calculado como [WC-65] × [TG] em homens, e [WC-58] × [TG] em mulheres e PALb foi calculada usando o valor mínimo da CC sendo 61,5 cm para mulheres e 71,5 cm para homens. Resultados: Houve correlação entre LAPa (0,506), LAPb (0,515) e HOMA-IR. O LAP foi melhor correlacionado com o HOMA-IR e mostrou maior área sob a curva do que o IMC, NC, WHR e SAD. Com base na análise da curva característica operacional do receptor, LAPb ≥47.40 e LAPa ≥52.5 foram os melhores valores de corte utilizados para identificar indivíduos com IR apresentando 68,8% e 68,2% de sensibilidade, e 68,6% e 68,6% de especificidade, respectivamente. Conclusão: O LAP pode ser um marcador clínico útil e simples para avaliar os factores de risco cardiometabólico na população idosa tratada num serviço de cuidados primários.

FUNDAMENTO: A doença cardiovascular é a principal causa de morte em diabéticos, tornando-se primordial a identificação dos indivíduos sob maior risco de eventos cardiovasculares. OBJETIVO: Avaliar o valor prognóstico da cintilografia miocárdica de perfusão com " gated SPECT" em pacientes com diabete melito (DM) e suspeita clínica de doença arterial coronariana. MÉTODOS: Estudo retrospectivo envolvendo 232 pacientes diabéticos submetidos à cintilografia miocárdica com " gated SPECT" . Foram avaliados os parâmetros da cintilografia de perfusão (escores e número de segmentos alterados) e da função ventricular (fração de ejeção, volumes e contratilidade do ventrículo esquerdo). Foram considerados eventos cardiovasculares futuros ocorrência de óbito cardíaco, síndrome coronariana isquêmica aguda, procedimentos de revascularização ou acidente vascular encefálico. Foi realizada a análise uni e multivariada pelo modelo de regressão logística múltipla (p < 0,05). RESULTADOS: Estiveram associados com desfechos futuros na análise univariada: idade (p=0,02); angina de peito (p=0,01); tratamento com insulina (p=0,02); anormalidades na perfusão miocárdica (p 3 (p=0,0001) e o número de segmentos alterados > 3 (p=0,0001) foram preditores de eventos. CONCLUSÃO: A cintilografia miocárdica com " gated SPECT" adiciona informações independentes para a estratificação do risco de eventos cardiovasculares futuros em pacientes com diabete melito e suspeita de doença arterial coronariana.BACKGROUND: The cardiovascular disease is the main cause of death among diabetic patients, which makes it crucial to identify the individuals at higher risk of cardiovascular events. OBJECTIVE: To evaluate the prognostic value of scintigraphy with gated single photon emission computed tomography (SPECT) in patients with diabetes mellitus (DM) and suspected coronary artery disease. METHODS: Retrospective study with 232 diabetic patients submitted to scintigraphy with gated SPECT. Perfusion Gated SPECT (scores and number of altered segments) as well as ventricular function parameters (ejection fraction, left ventricle (LV) volume and contractility) were evaluated. Cardiac death, acute ischemic coronary syndrome, revascularization procedures or encephalic vascular accident were considered future cardiovascular events. The uni- and multivariate analyses were carried out by the multiple logistic regression model (p< 0.05). RESULTS: At the univariate analysis, age (p=0.02), chest angina (p=0.01), insulin therapy (p=0.02), myocardial perfusion abnormalities (p 3 (p=0.0001) and the number of altered segments > 3 (p=0.0001) were predictors of cardiovascular events. CONCLUSION: The myocardial scintigraphy with gated SPECT adds independent information to the stratification of the risk of future cardiovascular events in patients with DM and suspected coronary artery disease.

OBJECTIVE: To assess the prognostic value of Technetium-99m-labeled single-photon emission computerized tomography (SPECT) in the follow-up of patients who had undergone their first myocardial revascularization. METHODS: We carried out a retrospective study of 280 revascularized patients undergoing myocardial scintigraphy under stress (exercise or pharmacological stress with dipyridamole) and at rest according to a 2-day protocol. A set of clinical, stress electrocardiographic and scintigraphic variables was assessed. Cardiac events were classified as "major" (death, infarction, unstable angina) and "any" (major event or coronary angioplasty or new myocardial revascularization surgery). RESULTS: Thirty-six major events occurred as follows: 3 deaths, 11 infarctions, and 22 unstable anginas. In regard to any event, 22 angioplasties and 7 new surgeries occurred in addition to major events, resulting a total of 65 events. The sensitivity of scintigraphy in prognosticating a major event or any event was, respectively, 55% and 58%, showing a negative predictive value of 90% and 83%, respectively. Diabetes mellitus, inconclusive stress electrocardiography, and a scintigraphic visualization of left ventricular enlargement were significant variables for the occurrence of a major event. On multivariate analysis, abnormal myocardial scintigraphy was a predictor of any event. CONCLUSION: Myocardial perfusion tomography with Technetium-99m may be used to identify high-risk patients after their first myocardial revascularization surgery. OBJETIVO: Avaliar o valor prognóstico da tomografia miocárdica de perfusão (SPECT) com tecnécio-99m no acompanhamento de pacientes após a primeira cirurgia de revascularização miocárdica. MÉTODOS: Estudo retrospectivo com 280 pacientes revascularizados com cintigrafia miocárdica sob estresse (esforço físico ou farmacológico com dipiridamol) e repouso em protocolo de 2 dias. Foi avaliado um conjunto de variáveis clínicas, eletrocardiográficas de esforço e cintigráficas. Os eventos cardíacos foram definidos como "maior" (morte, infarto, angina instável) e "qualquer" (evento maior ou angioplastia coronariana ou nova cirurgia de revascularização). RESULTADOS: Ocorreram 36 eventos maiores: 3 óbitos, 11 infartos, 22 angina instáveis. Com relação a qualquer evento, 22 angioplastias e 7 novas cirurgias se somaram aos eventos maiores, totalizando 65 eventos. A sensibilidade da cintigrafia em prognosticar evento maior e qualquer evento foi, respectivamente, 55% e 58%, evidenciando um valor preditivo negativo de 90% e 83%. A presença de diabetes mellitus, de eletrocardiograma de esforço inconclusivo e do aspecto cintigráfico de aumento do ventrículo esquerdo foram variáveis significativas para a ocorrência de evento maior. Pela análise multivariada, uma cintigrafia miocárdica anormal foi preditora de qualquer evento. CONCLUSÃO: A tomografia miocárdica de perfusão com tecnécio-99m pode ser usada para identificar pacientes de maior risco, após a primeira cirurgia de revascularização miocárdica.

The cardiovascular disease is the main cause of death among diabetic patients, which makes it crucial to identify the individuals at higher risk of cardiovascular events.To evaluate the prognostic value of scintigraphy with gated single photon emission computed tomography (SPECT) in patients with diabetes mellitus (DM) and suspected coronary artery disease.Retrospective study with 232 diabetic patients submitted to scintigraphy with gated SPECT. Perfusion Gated SPECT (scores and number of altered segments) as well as ventricular function parameters (ejection fraction, left ventricle (LV) volume and contractility) were evaluated. Cardiac death, acute ischemic coronary syndrome, revascularization procedures or encephalic vascular accident were considered future cardiovascular events. The uni- and multivariate analyses were carried out by the multiple logistic regression model (p0.05).At the univariate analysis, age (p=0.02), chest angina (p=0.01), insulin therapy (p=0.02), myocardial perfusion abnormalities (p0.0001), the number of segments involved (p=0.0001), the perfusion scores (p=0.0001), the ejection fraction (p=0.004), the final systolic volume (p=0.03) and the finding of segmental alteration at the left ventricle contractility (p0.0001) were associated with future events at the univariate analysis. At the multivariate analysis, the male sex (p=0.007), age (p=0.03), angina (p=0.001), insulin therapy (p=0.007) and the SDS3 (p=0.0001) and the number of altered segments3 (p=0.0001) were predictors of cardiovascular events.The myocardial scintigraphy with gated SPECT adds independent information to the stratification of the risk of future cardiovascular events in patients with DM and suspected coronary artery disease.
