Prevalence of Angina Pectoris and Associated Factors in the Adult Population of Brazil: National Survey of Health, 2019 / Prevalência e fatores associados da angina do peito na população adulta do Brasil: Pesquisa Nacional de Saúde, 2019

ABSTRACT: Objective: to estimate the prevalence and factors associated with angina pectoris in the Brazilian adult population and per federated units. Methods: Cross-sectional descriptive study that analyzed data from the National Survey of Health 2019 and assessed the prevalence of angina in the Brazilian population. Angina was defined as chest pain or discomfort when climbing hills or stairs, or when walking fast on flat terrain (angina I) or when walking at normal speed on flat terrain (angina II). Prevalence, crude and adjusted prevalence ratios were calculated, with a 95% confidence interval, according to sociodemographic characteristics (sex, age group, self-reported race/skin color and region of residence) and federative units. Results: The prevalence of mild angina (grade I) was 8.1% and of moderate/severe angina (grade II) was 4.5%, being both more prevalent in women (9.8 and 5.5%, respectively). The prevalence increased progressively with age and was inversely proportional to years of formal study. Grade I angina was higher in individuals self-reportedly black and residents of Sergipe (10,4%). Angina II was more prevalent in people self-reportedly brown and living in Amazonas (6.3%). Conclusion: Angina affects more than 10% of the Brazilian population aged 18 years old and more, with higher prevalence in states in the North and Northeast. This is a problem that affects the most vulnerable populations unequally, which places coronary heart disease as a public health problem and points to the need to think about public policies aimed at these strata of the population.

RESUMO: Objetivo: Estimar a prevalência e fatores associados à angina do peito na população adulta brasileira e por unidades federadas. Métodos: Estudo transversal descritivo, que analisou os dados da Pesquisa Nacional de Saúde 2019 e avaliou a angina na população brasileira. A angina foi definida como dor ou desconforto no peito ao subir ladeiras ou um lance de escadas, ou ao caminhar rapidamente no plano (angina I) ou em velocidade normal no plano (angina II). Foram calculadas as prevalências, razão de prevalência bruta e ajustada, com intervalo de confiança de 95%, segundo características sociodemográficas (sexo, faixa etária, raça/cor da pele autodeclarada e região de moradia) e unidades federativas. Resultados: A prevalência de angina leve (grau I) foi de 8,1% e da angina moderada/grave (grau II), 4,5%, ambas mais prevalentes em mulheres (9,8 e 5,5%, respectivamente). As prevalências aumentaram progressivamente com o avanço da idade e foram inversas aos anos de estudo formal. Angina grau I foi mais elevada em indivíduos da raça/cor da pele autodeclarada preta e residentes em Sergipe (10,4%). A angina II foi mais prevalente em pessoas de raça/cor da pele autodeclarada parda, que vivem no Amazonas (6,3%). Conclusão: A angina afeta mais de 10% da população brasileira acima de 18 anos, com maior prevalência em estados do Norte e do Nordeste. É um agravo que atinge de forma desigual as populações mais vulneráveis, revelando a importância da doença coronariana como problema de saúde pública e a necessidade de pensar em políticas públicas voltadas para esses estratos da população.

Aspirin plus verapamil relieves angina and perfusion abnormalities in patients with coronary microvascular dysfunction and Chagas disease: a pilot non-randomized study

Abstract INTRODUCTION: Most patients with chronic cardiomyopathy of Chagas disease (CCCD) harbor a secondary cause of coronary microvascular dysfunction (CMD), for which there is no evidence-based therapy. We evaluated the impact of verapamil plus aspirin on symptoms and perfusion abnormalities in patients with CCCD and CMD. METHODS: Consecutive patients with angina pectoris, who had neither coronary artery obstructions nor moderate-severe left ventricular dysfunction (left ventricular ejection fraction > 40%) despite showing wall motion abnormalities on ventriculography, were referred for invasive angiography and tested for Chagas disease. Thirty-two patients with confirmed CCCD and ischemia on stress-rest SPECT myocardial perfusion scintigraphy (MPS) were included. Clinical evaluation, quality of life (EQ-5D/ Seattle Angina Questionnaire), and MPS were assessed before and after 3 months of treatment with oral verapamil plus aspirin (n=26) or placebo (n=6). RESULTS: The mean patient age was 64 years, and 18 (56%) were female. The ischemic index summed difference score (SDS) in MPS was significantly reduced by 55.6% after aspirin+verapamil treatment. A decrease in SDS was observed in 20 (77%) participants, and in 10 participants, no more ischemia could be detected. Enhancements in quality of life were also detected. No change in symptoms or MPS was observed in the placebo group. CONCLUSIONS: This low-cost 3-month treatment for patients diagnosed with CCCD and CMD was safe and resulted in a 55.6% reduction in ischemic burden, symptomatic improvement, and better quality of life.

Left main coronary artery compression by the right pulmonary artery in a patient with congenital pulmonic stenosis / Compresión del tronco coronario izquierdo por la arteria pulmonar derecha en un paciente con estenosis pulmonar congénita

Abstract Congenital pulmonary stenosis (PS) can be associated with pulmonary artery (PA) dilatation. In some cases, this can cause compression of nearby structures including the left main coronary artery (LMCA). This compression causes angina and is considered an indication for surgical treatment. We present the case of a patient with PS and angina secondary to LMCA compression by the right PA and review the main indications and options for surgical treatment.

Resumen La estenosis pulmonar congénita se asocia a dilatación de la arteria pulmonar. En algunos casos esto puede causar compresión de las estructuras adyacentes incluyendo el tronco de la coronaria izquierda. Esta compresión causa angina y es considerada una indicación para tratamiento quirúrgico. Presentamos el caso de un paciente con estenosis pulmonar y angina secundaria a compresión del tronco de la coronaria izquierda por la arteria pulmonar derecha y revisamos las indicaciones y opciones de tratamiento quirúrgico.

Interferencia analítica en la determinación de troponina por anticuerpos heterófilos / Interference in the determination of Troponin due to heterophile antibodies

Resumen Por su elevada especificidad y sensibilidad, y a raíz de la tercera definición universal de infarto estas isoformas cardiacas han sido aceptadas en el ámbito internacional como los biomarcadaores de elección en la práctica clínica para el diagnóstico de síndrome coronario agudo, preferibles a la determinación de las enzimas creatina quinasa y su isoforma MB. Se presenta el caso de un varón de ochenta años, quien, de manera persistente, tuvo valores elevados de troponinas, pese a evolución clínica no compatible con síndrome coronario agudo ni otras causas de elevación de este biomarcador.

Abstract Due to its elevated specificity and sensitivity, and on being the third universal definition of myocardial infarction, these cardiac isoforms have been accepted internationally as the biomarkers of choice in clinical practice for the diagnosis of acute coronary syndrome, and are preferable to the determinations of creatine kinase and its MB isoform. A case is presented on an eighty year-old man, who persistently had elevated Troponin values, despite a clinical course that was incompatible with an acute coronary syndrome or any other causes of elevation of this biomarker.

Spinal Cord Electrical Stimulation for Refractory Angina Treatment

Cardiovascular disease (CVD) is the main cause of death worldwide, including in Brazil. Angina pectoris is a challenging disease because its clinical manifestation is not always related to the degree of obstruction. Visceral pain fromany source can be totally disabling. It influences all aspects of the life of a patient and it can be one of the main causes of absence from work and of family disruption. Spinal cord electrical stimulation (SCES) has been traditionally applied for the treatment of neuropathic pain, with good to excellent results. Visceral pain syndrome can be as debilitating and disabling as somatic or neuropathic pain; however, there seems to be a lack of consensus on the appropriate treatment and strategies for these disorders. Themajor difference of SCES for visceral pain, compared to postlaminectomy syndrome or to regional complex syndrome, is the number of stimulated dermatomes. In most viscera, the somatotopic arrangement has two to four medullar levels, sometimes requiring laterality. After reviewing the literature, we have concluded that SCES is now a viable, low-risk option with satisfactory results for the treatment of neuropathic and visceral pain; therefore, it can be used in refractory angina after the failure of standard therapy. However, further studies are required to increase the application and efficacy of this procedure in the clinical practice.

A Rare Cause of Angina After Coronary Bypass Grafting; Left İnternal Mammary Artery to Pulmonary Artery Fistula and Successful Treatment with Transcatheter Coil Embolization / Uma Causa Rara de Angina Após Revascularização do Miocárdio: Fístula da Artéria Mamária Interna Esquerda para Artéria Pulmonar e Tratamento Bem-Sucedido com Embolização Transcateter com Molas

Abstract Fistula from left internal mammary artery (LIMA) to pulmonary artery (PA) is rarely encountered in daily practice. In recent years, endovascular therapy options have emerged for the treatment of fistula formations and replaced with surgery. A 53-year-old man admitted to our outpatient clinic with symptoms of typical angina and shortness of breath despite optimal medical therapy. In his relevant history, he had a coronary artery bypass graft (CABG) operation in 2009 in which his LIMA was anastomosed to left anterior descending (LAD) and ramus artery sequentially. Coronary angiography including selective imaging of LIMA demonstrated a fistula formation originating from the proximal portion of the LIMA and draining to PA. After successful closure of fistula with transcatheter coil embolization, the patient was discharged without any complication and symptom. In conclusion, although LIMA to PA fistula is an infrequent clinical condition, it should be considered as a potential cause of persistent angina after CABG operation. Treatment options include conservative medical therapy, surgical ligation and endovascular interventions. The best therapy should be individualised for each patient in respect to patient's symptoms, surgical compatibility and anatomy of fistula.

Resumo A fístula da artéria mamária interna esquerda (AMIE) para a artéria pulmonar (AP) é raramente encontrada na prática diária. Nos últimos anos, opções de terapia endovascular surgiram para o tratamento de formações de fístula e foram substituídas por cirurgia. Um homem de 53 anos de idade, internado em nosso ambulatório com sintomas de angina típica e falta de ar, apesar da terapia clínica ideal. Em seu histórico relevante, ele teve uma cirurgia de revascularização miocárdica (CRM) em 2009, na qual sua AMIE foi anastomosada à descendente anterior esquerda (DAE) e à artéria ramus sequencialmente. A angiografia coronária, incluindo imagens seletivas da AMIE, demonstrou uma formação de fístula proveniente da porção proximal da AMIE e drenando para AP. Após o fechamento bem-sucedido da fístula com embolização transcateter com mola, o paciente recebeu alta sem qualquer complicação e sintoma. Em conclusão, embora fístula entre AMIE e AP seja uma condição clínica pouco frequente, deve ser considerada como uma causa potencial de angina persistente após a operação de revascularização do miocárdio. As opções de tratamento incluem terapia médica conservadora, ligadura cirúrgica e intervenções endovasculares. A melhor terapia deve ser individualizada para cada paciente em relação aos sintomas do paciente, compatibilidade cirúrgica e anatomia da fístula.

La medición de los signos vitales es de gran importancia en el consultorio dental, de esta forma podemos obtener una visión objetiva y anticipada del estado funcional del paciente. Según la información obtenida, se tomarán decisiones terapéuticas. El odontólogo debe saber que el seguimiento clínico y el uso de la técnica adecuada para sus mediciones representan un aspecto muy relevante para prevenir emergencias en el consultorio dental. El odontólogo debe medir los signos vitales antes, durante y después del procedimiento dental y, del mismo modo, debe estar involucrado en la situación individual de cada paciente y proporcionar medidas higiénicodietéticas para mejorar su calidad de vida. La evaluación continua de los signos vitales durante el procedimiento quirúrgico dental, en el que se usan anestésicos locales, es particularmente relevante en este caso, ya que puede ayudarnos a prevenir complicaciones como arritmias cardiacas, crisis hipertensivas o angina de pecho. El objetivo de este artículo es promover en toda la profesión odontológica, el monitoreo de los signos vitales, su técnica de medición correcta y su correlación con otros datos de un historial completo médico y dental (AU)

The measurement of vital signs is of great importance in the dental office, this way we can obtain an objective and anticipated vision of the functional state of the patient. According to the information obtained, therapeutic decisions will be made. The dentist must know that monitoring and using the appropriate technique for its measurements, represents a very relevant aspect for the emergency in the dental office. The dentist must measure the vital signs before, during and after the dental procedure, likewise, they must be involved in the individual situation of each patient and provide hygienic-dietetic measures to improve their quality of life. The continuous assessment of vital signs during the dental surgical procedure, in which local anesthetics are used, is particularly relevant in this case since it can help us prevent complications such as cardiac arrhythmias, hypertensive crisis or angor pectoris. The objective of this article is to promote throughout the dental profession, the monitoring of vital signs, their correct measurement technique and their correlation with other data from a complete medical and dental history (AU)

Lateral costal artery: clinical importance of an accessory thoracic artery

Abstract The lateral costal artery has sometimes been identified as the culprit for the "steal phenomenon" after coronary artery bypass grafting, besides being occasionally used for myocardial revascularization. Its branches make anastomoses with the internal thoracic artery through lateral intercostal arteries. We aim to report, on three cases, the clinical significance of a well-developed lateral costal artery after coronary artery bypass grafting. Two out of three patients who underwent coronary artery bypass graft surgery in our center between June 2010 and August 2017, applied to us with stable angina pectoris, while the third one was diagnosed with acute coronary syndrome after applying to the emergency department. In coronary cineangiography, in all three cases, a well-developed accessory vessel arising from the proximal 2.5 cm segment of the left internal thoracic artery coursed as far as the 6th rib was detected, and it was confirmed to be the lateral costal artery. A stable angina pectoris in two of the patients was thought to be the result of steal phenomenon caused by the well-developed lateral costal artery. In the two cases with stable angina pectoris the lateral costal artery was obliterated via coil embolization. In the other case with the proximal left anterior descending artery stenosis, before percutaneous coronary intervention, the lateral costal artery was obliterated via coil embolization and the occluded subclavian artery was stented. Routine visualization in cineangiography and satisfactory surgical exploration of the left internal thoracic artery could be very helpful to identify any possible accessory branch of the left internal thoracic artery like the lateral costal artery.

Caracterización de los pacientes con diagnóstico presuntivo de síndrome coronario agudo sin elevación del segmento ST que asisten a un servicio de urgencias / Profile of patients with non-ST elevation acute coronary syndrome that attend an Emergency Department

Resumen El dolor torácico es uno de los principales motivos de consulta al sistema de urgencias, y este es secundario a condiciones como el síndrome coronario agudo entre otras. Para su diagnóstico se requiere no sólo el resultado de la troponina, sino una evaluación clínica completa en la que se tengan en cuenta factores de riesgo cardiovascular, características del dolor y hallazgos electrocardiográficos. La interpretación inadecuada de las troponinas ultrasensibles lleva a que se someta al paciente a riesgos innecesarios a causa de estudios como el cateterismo cardiaco. Se llevó a cabo un estudio de corte trasversal en un hospital de Bogotá, en el que la causa principal de consulta en el servicio de urgencias fue el dolor torácico, y la primera causa de hospitalización en Cardiología el síndrome coronario agudo. Se recolectaron datos de 411 pacientes a quienes se les realizó arteriografía coronaria, la mayoría hombres con factores de riesgo como hipertensión arterial, tabaquismo y un evento coronario previo. Dentro de los estudios paraclínicos, la fracción de eyección promedio estuvo cercana al 50% y sólo en 201 pacientes se encontraron lesiones epicárdicas significativas.De la muestra analizada, el 13% tenía creatinina mayor de 1,5 mg/dl como causa alterna de elevación del biomarcador y 28% tenía disfunción ventricular izquierda de algún grado. La mayoría de los pacientes en quienes no se documentaron lesiones angiográficamente significativas en el cateterismo cardiaco, la troponina no cumplía criterios de positividad con base en el aumento del 20% respecto al valor inicial si este era positivo o de 50% en caso de que el primer valor fuese negativo. Adicionalmente, del grupo de pacientes con enfermedad coronaria angiográficamente significativa fue más frecuente la combinación de tres o más factores de riesgo cardiovascular en presencia de biomarcador positivo.

Abstract Chest pain is one of the main reasons for consulting the Emergency Department, and it is secondary to conditions, such as acute coronary syndrome. For its diagnosis, it not only requires a Troponin result, but also a full clinical evaluation, in which factors like cardiovascular risk have to be taken into account, as well as characteristics of the pain and the findings on the electrocardiogram. The poor interpretation of the ultrasensitive Troponins leads to the patient being subjected to unnecessary risks due to studies such as cardiac catheterisation. A cross-sectional study was conducted in a hospital in Bogota, in which chest pain was the main reason for consulting the Emergency Department, and acute coronary syndrome the first cause of admission to Cardiology. The study included a total of 411 patients on whom a coronary angiography was performed. The majority were males with risk factors such as arterial hypertension, smokers, and with a previous coronary event. Among the para-clinical studies, the mean ejection fraction was around 50%, and significant epicardial lesions were found in only 201 patients.Of the sample analysed, 13% had a creatinine greater than 1.5 mg/dl as an alternative cause of the elevation of the biomarker, and 28% had some degree of left ventricular function. the majority of patients that did not have significant angiographic lesions in the cardiac catheterisation documented, the Troponin did not meet the criteria for being positive, based on an increase of 20% as regards the initial value if this was positive or 50% in the case where the first value was negative. Furthermore, of the patient group with significant angiographic coronary disease, the combination of three or more cardiovascular risk factors was the most frequent in the presence of a positive biomarker.

Emergências cardiovasculares agudas: prevenção, diagnóstico e manejo odontológico / Acute cardiovascular emergencies: prevention, diagnosis and dental management

As emergências cardiovasculares agudas são complicações cardíacas com altos índices de mortalidade e podem ocorrer durante o atendimento odontológico de cardiopatas. Contribuir com medidas de prevenção, diagnóstico e manejo odontológico de emergências cardiovasculares agudas durante o tratamento dentário através de uma revisão integrativa. A anamnese minuciosa associada a medidas de controle de estresse/ ansiedade são as principais formas de prevenir a ocorrência de eventos cardíacos no consultório odontológico. Durante a crise, o conhecimento dos principais sinais e sintomas é fundamental no diagnóstico diferencial de cardiopatias agudas e, após estabelecido, devem-se iniciar os primeiros socorros básicos através do acionamento do serviço de emergência, seguido pelo posicionamento corporal adequado do paciente e administração dos protocolos farmacológicos específicos para cada situação. O consultório odontológico deve obrigatoriamente possuir os equipamentos necessários para monitorização dos sinais vitais durante o evento cardiovascular agudo e garantir a disponibilização de oxigênio para que o cirurgião-dentista possa iniciar os protocolos de ressuscitação caso o paciente evolua para uma parada cardiorrespiratória. O manejo odontológico das emergências cardiovasculares agudas inicia-se com cuidados preventivos específicos, realização do diagnóstico correto da cardiopatia aguda, tomada de conduta adequada das complicações cardíacas que possam ocorrer durante o tratamento odontológico, objetivando a diminuição da morbimortalidade dessas emergências

Acute cardiovascular emergencies are cardiac complications with high mortality rates, and can occur during the dental care of cardiac patients. To contribute to the prevention, diagnosis and dental management of acute cardiovascular emergencies during dental treatment, through an integrative review. A detailed anamnesis, associated with measures of stress/anxiety control, are the main ways to prevent the occurrence of cardiac events in the dental office. During the crisis, a knowledge of the main signs and symptoms is fundamental in the differential diagnosis of acute heart diseases and once established, basic first aid should be given, activating the emergency services followed by the appropriate body positioning of the patient and administration of specific pharmacological protocols for each situation. The dental office must have the equipment needed to monitor the vital signs during the acute cardiovascular event, and ensure the availability of oxygen, so that the dental surgeon can initiate resuscitation protocols if the patient goes into cardiopulmonary arrest. Dental management of acute cardiovascular emergencies begins with specific preventive care, a correct diagnosis of acute cardiopathy, and correct management of cardiac complications that can occur during dental treatment, aiming to reduce the morbidity and mortality of these emergencies

Cardiomiopatía de tako-tsubo en un paciente con estenosis aórtica moderada. Caso clínico y revisión bibliográfica / Tako-tsubo cardiomyopathy in a patient with moderate aortic stenosis. Case report and literature review

El síndrome de tako-tsubo (STT) o cardiomiopatía inducida por estrés es una afección cardíaca que se manifiesta de manera similar a un infarto de miocardio, aunque tiene características particulares: estrés agudo físico y/o psíquico, como causa desencadenante, cambios del segmento ST y onda T en el electrocardiograma, elevación moderada de los biomarcadores de mionecrosis (troponina ultrasensible), trastorno de la movilidad miocárdica de los segmentos medios y apicales del ventrículo izquierdo y arterias coronarias sin lesiones angiográficamente evidentes (obstrucción o ruptura de placa). El presente artículo describe a una paciente de sexo femenino de 67 años de edad, que ingresó al hospital por dolor precordial opresivo característico de un síndrome coronario agudo, cambios electrocardiográficos inespecíficos de isquemia y arterias coronarias normales, cuyo diagnóstico fue síndrome de tako-tsubo y, concomitantemente, estenosis aórtica moderada secundaria a válvula aórtica bivalva de patrón típico (fusión de la coronaria derecha e izquierda); esta asociación patológica no está descrita en la literatura médica. Se realizó una revisión bibliográfica poniendo hincapié en el diagnóstico de esta infrecuente patología.

Tako-tsubo syndrome (STT) or stress-induced cardiomyopathy is a cardiac condition with a clinical presentation similar to a myocardial infarction and specific features of this syndrome, such as: causes triggering of acute physical and / or psychic stress, ST segment changes, and T wave on the electrocardiogram, moderate elevation of myonecrosis biomarkers (ultrasensitive troponin), myocardial mobility disorder of the mid and apical segments of the left ventricle and coronary arteries without any evident angiographical lesions (obstruction or plaque rupture). This article will describe a female patient of 67 years old, who entered in the hospital due to oppressive precordial pain characteristic of an acute coronary syndrome, non-specific electrocardiographic changes of ischemia and normal coronary arteries, which we concluded with takotsubo syndrome; concomitantly moderate aortic stenosis secondary to a trival aortic valve with raphe confirmed by echocardiography; Clinical association is not described in medical literature. Later we will make a bibliographical review on the subject with emphasis on the diagnosis of this infrequent pathology.Key words: urethra, foreign body.

Doenças isquêmicas do coração e masculinidade como fatores de risco cardiovascular / Cardiopatía isquémica y masculinidad como factores de riesgo cardiovascular / Ischemic heart disease and masculinity as cardiovascular risk factors

RESUMO Introdução: Estereótipos de gênero traduzem concepções e ações masculinas sobre adoecimento e autocuidado, implicando em indicadores de saúde. Objetivo: Estimar a prevalência de fatores de risco cardiovascular e doenças isquêmicas do coração em homens; discutir a relação entre masculinidade e a exposição a fatores de risco cardiovascular e a essas doenças. Métodos: Estudo epidemiológico, descritivo, retrospectivo, realizado por meio de dados secundários, oriundos do Vigitel e DATASUS, para homens adultos, no Brasil, no período de 2010-2014. Resultados: Os homens, comparados às mulheres, apresentaram maior prevalência para tabagismo (22,5 porcento), sobrepeso (56,5 porcento), consumo abusivo de bebidas alcoólicas (23,4 porcento), inatividade física (16,2 porcento) e maior tempo de televisão (25,8 porcento). Foram vítimas de maior mortalidade por Angina Pectoris (51,4 porcento), Infarto Agudo do Miocárdio (58,9 porcento) e Doença Isquêmica Crônica do Coração (55,8 porcento), com tendência crescente, nos últimos cinco anos. Comportamentos masculinos expressam resistência ao cuidado à saúde e estão associados a fatores socioculturais e institucionais que, em conjunto ou individualmente, potencializam a exposição às situações de risco e a dificuldade de reconhecerem suas necessidades e procurarem os serviços de saúde. Conclusão: Homens estão mais expostos a fatores de risco e a mortalidade por doença cardiovascular e as construções sociais de gênero são determinantes do processo saúde/doença(AU)

RESUMEN Introducción: Los estereotipos de género traducen concepciones y acciones masculinas acerca de la enfermedad y el autocuidado, influyendo en los indicadores de salud. Objetivo: Estimar la prevalencia de factores de riesgo cardiovascular y la enfermedad isquémica del corazón en los hombres; discutir la relación entre la masculinidad y la exposición a factores de riesgo cardiovascular y estas enfermedades. Métodos: Estudio epidemiológico, descriptivo, retrospectivo, realizado con datos secundarios del VIGITEL y el DATASUS para los hombres adultos, en Brasil, en el período 2010-2014. Resultados: Los hombres, en comparación con las mujeres, tuvieron mayor prevalencia de tabaquismo (22,5 por ciento), sobrepeso (56,5 por ciento), consumo abusivo de alcohol (23,4 por ciento), inactividad física (16,2 por ciento) y tiempo de televisión (25,8 por ciento). Fueron víctimas de mayor mortalidad por angina de pecho (51,4 por ciento), infarto agudo de miocardio (58,9 por ciento) y cardiopatía isquémica crónica (55,8 por ciento), con tendencia creciente en los últimos cinco años. Los comportamientos masculinos expresan resistencia al cuidado de la salud y están asociados con factores socio-culturales e institucionales que, en conjunto o individualmente, potencian la exposición a situaciones de riesgo y la dificultad de reconocer sus necesidades y buscar los servicios de salud. Conclusión: Los hombres están más expuestos a factores de riesgo y mortalidad por enfermedades cardiovasculares y las construcciones sociales de género son determinantes del proceso salud-enfermedad(AU)

ABSTRACT Introduction: Gender stereotypes translate male conceptions and actions of illness and self-care, implying in health indicators. Objectives: To estimate the prevalence of cardiovascular risk factors and ischemic heart disease in men; to discuss the relationship between masculinity and exposure to cardiovascular risk factors and these diseases. Methods: Epidemiological, descriptive and retrospective study, realized through secondary data originated from Vigitel and DATASUS, for adult men, in Brazil, of the 2010-2014 period. Results: Men, compared to women, had higher prevalence of smoking (22.5 percent), overweight (56.5 percent), abusive alcohol consumption (23.4 percent), physical inactivity (16.2 percent) and longer television time (25.8 percent). They were victims of higher mortality from Angina Pectoris (51.4 percent), Acute Myocardial Infarction (58.9 percent) and Chronic Ischemic Heart Disease (55.8 percent), with a growing trend, in the last five years. Male behaviors express health care resistance and are associated with socio-cultural and institutional factors that, together or individually, potentialize the exposure to risk situations and the difficulty of recognize their needs and seek the health services. Conclusion: Men are more expose to risk factors and cardiovascular disease mortality and social constructions of gender are determinants of the health-disease process(AU)
