Histologia do miocárdio normal e infartado / Histology of normal and infarcted myocardial

Introdução: O infarto do miocárdio é uma patologia que apresenta grande morbidade e mortalidade. Ele é resultado da necrose de cadiomiócitos provocada por dificuldade de oxigenação. Objetivo: O objetivo deste estudo foi rever a histologia do miocárdio e suas alterações histológicas quando infartado. Método: Trata-se de uma revisão narrativa em livros técnicos e artigos cinetíficos publicados na SciELO e PubMed. Resultados: O miocárdio é formado por cardiomiócitos, que se contraem em função dos sarcômeros dispostos em suas miofibrilas e apresentam eficiente comunicação elétrica entre si por meio de junções comunicantes. O infarto do miocárdio promove morte dos cardiomiócitos, alterações em elementos citoplasmáticos e na condução elétrica além da formação de tecido cicatricial fibroso. Conclusão: Em conclusão, o miocárdio é altamente vascularizado e formado por cardiomiócitos contráteis alongados e de composição sarcométrica. Em condições isquêmicas, como no infarto do miocárdio, há uma remodelação histológica no tecido muscular cardíaco que leva à fibrose e perda das funções contráteis.

Introduction: Myocardial infarction is a pathology that presents high morbidity and mortality. It is the result of cardiomyocyte necrosis caused by oxygenation difficulties. Objective: The aim of this study was to review the histology of the myocardium and its histological changes when infarcted. Method: This is a narrative review of technical books and scientific articles published in SciELO and PubMed. Results: The myocardium is formed by cardiomyocytes, which contract due to the sarcomeres arranged in their myofibrils and present efficient electrical communication with each other through gap junctions. Myocardial infarction promotes the death of cardiomyocytes, alterations in cytoplasmic elements and electrical conduction, in addition to the formation of fibrous scar tissue. Conclusion: In conclusion, the myocardium is highly vascularized and formed by elongated contractile cardiomyocytes with a sarcometric composition. In ischemic conditions, such as myocardial infarction, there is histological remodeling in cardiac muscle tissue that leads to fibrosis and loss of contractile functions

Aspectos clinicoepidemiológicos, electrocardiográficos, ecocardiográficos y terapéuticos en pacientes diabéticos con infarto agudo de miocardio / Clinical epidemiological, electrocardiographic, echocardiographic and therapeutic aspects in diabetic patients with acute heart attack

Introducción: La diabetes mellitus se encuentra entre las enfermedades crónicas no transmisibles más comunes en el mundo, y se estima que para el 2030 será diagnosticada en 7,7 % de la población mayor de 18 años, es decir, en 430 millones de individuos. Objetivo: Caracterizar a pacientes diabéticos que presentaron infarto agudo de miocardio con elevación del segmento ST, según variables clinicoepidemiológicas, electrocardiográficas, ecocardiográficas y terapéuticas. Métodos: Se realizó un estudio descriptivo, desde enero hasta diciembre de 2019, de 137 pacientes con antecedente de diabetes mellitus que presentaron infarto agudo de miocardio con elevación del segmento ST, atendidos en el Servicio de Cardiología del Hospital Provincial Clínico-Quirúrgico Docente Saturnino Lora de Santiago de Cuba. Entre las variables analizadas figuraron la edad, el sexo, la clase funcional, las complicaciones, la función sistólica y la diastólica del ventrículo izquierdo, la terapia de reperfusión empleada y el estado del paciente al egreso. Resultados: En la serie predominaron el sexo masculino y el grupo etario mayor de 60 y más años. Se observó que el infarto agudo de miocardio en la topografía anterior presentara más complicaciones, así como mayor número de pacientes con tratamiento trombolítico y combinado. Asimismo, la mayoría de los pacientes egresaron vivos, lo cual se correspondió, además, con que recibieran terapia trombolítica. Al analizar a los pacientes con alteraciones segmentarias en el estudio ecocardiográfico, se obtuvo una primacía de los fallecidos en ese grupo en cuestión. Conclusiones: Los pacientes diabéticos que presentan infarto agudo de miocardio con elevación del segmento ST constituyen un grupo independiente con especificidades clínicas y ecocardiográficas y mayor riesgo de complicaciones mortales.

Introduction: Diabetes mellitus is not among the most common chronic non communicable diseases in the world, and is considered that by 2030 it will be diagnosed in the 7.7 % of the population over 18 years, that is to say, in 430 million individuals. Objective: To characterize diabetic patients that presented acute heart attack with elevation of the ST segment, according to clinical epidemiological, electrocardiographic, echocardiographic and therapeutic variables. Methods: A descriptive study was carried out from January to December, 2019 of 137 patients with history of diabetes mellitus that presented acute heart attack with elevation of the ST segment, assisted in the Cardiology Service of Saturnino Lora Teaching Clinical-Surgical Provincial Hospital in Santiago de Cuba. Among the analyzed variables figured the age, sex, functional class, complications, systolic and dyastolic function of the left ventricle, the therapy of reperfusion used and the state of the patient when discharged from the hospital. Results: In the series there was a prevalence of the male sex and the 60 and over age group. It was observed that the acute heart attack in the previous topography presented more complications, as well as higher number of patients with thrombolitic and combined treatment. Also, most of the patients were alive when discharged from the hospital, which also corresponded with the thrombolitic therapy received. When analyzing the patients with segmental alterations in the echocardiographic study, a primacy of the deceaseds was obtained in that group. Conclusions: The diabetic patients that present acute heart attack with elevation of the ST segment constitute an independent group with clinical and echocardiographic specificities, and more risk of mortal complications.

Setenta y cinco años de rehabilitación cardiovascular en México / Seventy-five years of cardiovascular rehabilitation in Mexico

Resumen Los pacientes que sufren una enfermedad cardiovascular requieren de atención médica integral que involucre las terapias y procedimientos necesarios para reintegrarlos de forma óptima a su vida personal, familiar, laboral y social. Las intervenciones dirigidas a alcanzar dichas metas se incluyen en los programas de rehabilitación cardiaca. Estos programas son diseáados para limitar los efectos dañinos tanto fisiológicos como psicológicos de las cardiopatías, reducir el riesgo de muerte súbita o reinfarto, controlar la sintomatología cardiovascular, estabilizar o revertir el proceso de aterosclerosis y mejorar el estado psicosocial y vocacional de los pacientes. Dichos programas existen en México desde la década de 1940 y han evolucionado a lo largo de los años, adaptándose a las condiciones de enfermedad presentes en nuestro país, desde su inicio con terapias para tratar a pacientes cardiopatía reumática hasta la aplicación del ejercicio físico en pacientes con insuficiencia cardiaca, cardiopatías congénitas complejas o hipertensión arterial pulmonar. Estas actividades son de índole transdisciplinaria e implica la integración de cardiólogos, fisioterapeutas, psicólogos y nutriólogos, entre otros. Actualmente, estos programas se han extendido a lo largo de la República Mexicana gracias a cardiólogos rehabilitadores egresados de las principales instituciones de salud del país, como son los Institutos de Salud, el IMSS (Instituto Mexicano del Seguro Social) y el ISSSTE (Instituto de Seguridad y Servicios Sociales para los Trabajadores del Estado). En este documento se expondrán los orígenes de la rehabilitación, desde la época prehispánica hasta la actual, destacando las contribuciones en docencia e investigación de los médicos que han ejercido en esta área en las instituciones previamente mencionadas.

Abstract Patients suffering from cardiovascular disease require comprehensive medical attention that involves therapies and procedures necessary to reintegrate them optimally to their personal, family, work and social life. Interventions aimed at achieving these goals are included in cardiac rehabilitation programs. These programs are designed to limit the harmful physiological and psychological effects of heart disease, reduce the risk of sudden death or reinfarction, control cardiovascular symptoms, stabilize or reverse the atherosclerosis process and improve the psychosocial and vocational status of patients. These programs have existed in Mexico since the 1940's and have evolved over the years, adapting to the disease conditions present in our country, starting with therapies to treat patients with rheumatic heart disease until the application of physical exercise in patients with heart failure, complex congenital heart disease or pulmonary arterial hypertension. These activities are of a transdisciplinary nature and involve the integration of cardiologists, physiotherapists, psychologists, and nutritionists among others. Currently, these programs have spread throughout the Mexican Republic thanks to rehabilitation cardiologists graduating from the main health institutions in the country such as Health Institutes, Mexican Social Security Institute and Institute of Security and Social Services of State Workers. In this document, the origins of rehabilitation from the pre-Hispanic era to the present will be discussed, highlighting the contributions in teaching and research of the physicians who have practiced in this area in the aforementioned institutions.

Public knowledge of cardiovascular disease and its risk factors in Tangail, Bangladesh: a cross-sectional survey

Background: Cardiovascular Disease (CVD) is a major public health problem throughout the world. In Bangladesh, the reliable data concerning various aspects of CVD is inadequate at present due to lack of national population-based surveys or central administrative health data. Given the rising incidence of CVDs in Bangladesh, an improved understanding of the CVD, symptoms and risk factors is needed. Hence, this study was performed to assess the level of knowledge towards CVD types, warning symptoms of heart attack or stroke, and CVD risk factors.Methods: A descriptive cross-sectional survey was conducted from May 2018 to June 2018 using standard questionnaire on a sample of 350 randomly selected Bangladeshi individuals. All the data of the study were input in SPSS (Statistical Package for the Social Sciences) version 20.0 software from IBM for windows and the gathered data thus analyzed using SPSS & Microsoft Excel.Results: The respondents’ knowledge about types of CVD, symptom heart attack, symptom of stroke and the risk factors of CVD are 38.9%, 67.7%, 35.7%, and 92.9% respectively. The most common risk factors of CVD found to be known by around than two-third of respondents were unhealthy diet (66.9%), physical inactivity (64.3), obesity (61.4%), and smoking (58.6%).Conclusions: The respondents’ knowledge about types of CVD, symptom heart attack, symptom of stroke and the risk factors of CVD are 38.9%, 67.7%, 35.7%, and 92.9% respectively. The most common risk factors of CVD found to be known by around than two-third of respondents were unhealthy diet (66.9%), physical inactivity (64.3), obesity (61.4%), and smoking (58.6%).

Factores pronósticos de supervivencia en pacientes con reanimación cardiopulmonar en un servicio de emergencias / Survival prognosis factors in patients with cardiopulmonary reanimation in an emergency service

Introducción: Los factores que influyen en que el paciente sobreviva luego de una reanimación cardiopulmonar hasta el alta hospitalaria no han sido descritos con certeza. Objetivo: Identificar los factores relacionados con la supervivencia al alta hospitalaria en pacientes que recibieron reanimación cardiopulmonar en un servicio de emergencias. Métodos: Se realizó un estudio analítico de cohortes, prospectivo, en 76 pacientes que recibieron reanimación cardiopulmonar en la Unidad de Cuidados Intensivos Emergentes del Hospital Provincial Docente Clínico-Quirúrgico Saturnino Lora Torres de Santiago de Cuba, de enero del 2016 a igual mes del 2018. Resultados: En el análisis univariado los factores que de manera independiente se asociaron a la supervivencia fueron el origen cardíaco (76,5 por ciento), el trazado electrocardiográfico de fibrilación ventricular-taquicardia ventricular sin pulso (64,7 por ciento), la no prolongación de la ventilación y la ausencia de sepsis (con 88,2 por ciento cada uno). Conclusiones: Se identificaron la recuperación neurológica y la no necesidad de drogas vasoactivas como los factores que influyeron directamente en la sobrevida hasta el alta hospitalaria

Introduction: The factors influencing in the survival of the patient after a cardiopulmonary reanimation up to the hospital discharge have not been described with accuracy. Objective: To identify the factors related to the survival at discharge in patients who received cardiopulmonary reanimation in an emergency service. Methods: An analytic cohorts prospective study was carried out in 76 patients who received cardiopulmonary reanimation in the Intensive Care Emergent Unit from Saturnino Lora Torres Teaching Clinical-Surgical Provincial Hospital in Santiago de Cuba, from January, 2016 to same month of 2018. Results: In the univariate analysis the associated factors to survival in an independent way were the heart origin (76.5 percent), the pattern of ventricular fibrillation/ ventricular tachicardia without pulse (64.7 percent), the non-continuation of ventilation and the sepsis absence (with 88.2 percent each of them). Conclusions: The neurological recovery and unnecessary use of vasoactive drugs were identified as the directly influencing factors in the survival up to the hospital discharge

Disfunção endotelial e periodontite ­ predição de risco para eventos cardiovasculares / Periodontitis and endothelial dysfunction ­ risk prediction for cardiovascular events

O objetivo deste estudo foi realizar uma revisão da literatura sobre a associação entre a disfunção endotelial, diagnosticada no exame de dilatação mediada por fluxo (DMF) da artéria braquial, e a periodontite crônica. Algumas evidências demonstraram uma associação entre as infecções periodontais e a disfunção endotelial. Alterações na função endotelial estão intimamente relacionadas com a aterosclerose, bem como seus fatores de risco, e constituem uma etapa intermediária na progressão de eventos adversos ao longo da história natural da doença cardiovascular, sendo esta uma das maiores causas de morte no mundo. A busca por artigos foi realizada no site Pubmed com as palavras-chave: periodontite, periodontite crônica, endotélio vascular, enfartos, derrames e doenças cardiovasculares. Após a busca, nove artigos foram selecionados para entrar nesta revisão. Os resultados dos estudos mostraram que indivíduos com periodontite apresentam a função endotelial prejudicada, quando comparados a indivíduos sem periodontite, e o tratamento da doença periodontal melhora a disfunção endotelial. Concluiu-se que a periodontite (DP) parece influenciar na função endotelial, e o seu tratamento pode melhorar a disfunção endotelial, um preditor de eventos cardiovasculares.

The aim of this study is to conduct a literature review on the association between endothelial dysfunction diagnosed on examination of flow-mediated dilatation (DMF) and chronic periodontitis. Some evidence shows an association between periodontal infections and endothelial dysfunction. Changes in endothelial function are closely related to atherosclerosis and its risk factors and is an intermediary step in the progression of adverse events throughout the natural history of cardiovascular disease, which is one of the largest causes of death worldwide. The electronic search was performed on Pubmed with the following key words: periodontitis, chronic periodontitis, vascular endothelium, heart attacks, strokes, cardiovascular diseases; overall, 9 articles were selected. The results of the studies showed that individuals with periodontitis have impaired endothelial function when compared to patients without periodontitis and the treatment of periodontal disease improves endothelial dysfunction. It was concluded that periodontal disease (PD) appears to influence on endothelial function and the treatment of periodontitis could improve endothelial dysfunction is a predictor of cardiovascular events.

Effect of vanillic acid on ischemia-reperfusion of isolated rat heart: Hemodynamic parameters and infarct size assays.

Vanillic acid is an oxidized form of vanillin produced during the conversion of vanillin to ferulic acid and has free radical scavenging, antioxidant and anti-inflammatory properties. In this study, we investigated the effects of vanillic acid on hemodynamic parameters and infarct size in ischemia-reperfusion of isolated rat heart. Adult male Sprague Dawley rats were randomly divided into control and treatment groups (n=10). The treatment groups were administered vanillic acid 5, 10 and 20 mg/kg orally for 10 days, then the hearts isolated and were exposed to 30 min ischemia and 1 h reperfusion, using langendorff apparatus. The effects of vanillic acid, on left ventricular developed pressure (LVDP), LV end diastolic pressure (LVEDP), LV pressure (LVP), peak rate of rise and fall of LVP (±dp/dt), coronary flow (CF), rate pressure product (RPP) and infarct size were examined. Rats administered with vanillic acid (10 and 20 mg/kg), displayed significantly improved recovery of LVEDP, RPP, LVDP, LVP and ± dp/dt as compared to control group. There was also significant beneficial effect of these two doses to reduce infarct size. Our results suggest that vanillic acid can effectively improve ventricular function and reduce infarct size in ischemia-reperfusion of isolated rat heart.
