Prevalence of myocardial bridges in the Mexican population: A morphometric and histological analysis.

BACKGROUND: Myocardial bridge (MB) is described as an abnormal band of myocardium covering a variable portion of any coronary artery. METHODS: The current study explores the presence of MB throughout the coronary arterial system and provides a morphometric description through instrumented dissection of a sample of 100 human hearts. The study shows a higher prevalence of MB in the Mexican population than in previous reports. RESULTS: In the total sample (n=100), MB was identified in 96% of it. A total of 421 MBs were observed, with a mean of 4.38mm (±0.28) per dissected heart. The most frequently affected vessel is the anterior interventricular artery where a total of 52 MBs were found, of the total sample studied. DISCUSSION: The high prevalence of MB among Mexican patients could be the result of a genetic association for this population or the neoformation of MB after birth due to lifestyle-associated factors. Further studies are required to better understand the high prevalence of MB among Mexican subjects.

Interdisciplinary training program for pediatric cardiorespiratory arrest using rapid cycle deliberate practice: A descriptive cross-sectional study

ABSTRACT BACKGROUND: cardiorespiratory arrest (CRA) is a severe public health concern, and clinical simulation has proven to be a beneficial educational strategy for training on this topic. OBJECTIVE: To describe the implementation of a program for pediatric cardiac arrest care using rapid-cycle deliberate practice (RCDP), the quality of the technique employed, and participants' opinions on the methodology. DESIGN AND SETTING: This descriptive cross-sectional study of pre- and post-performance training in cardiopul monary resuscitation (CPR) techniques and reaction evaluation was conducted in a hospital in São Paulo. METHODS: Multidisciplinary groups performed pediatric resuscitation in a simulated scenario with RCDP mediated by a facilitator. The study sample included professionals working in patient care. During the simulation, the participants were evaluated for their compliance with the CRA care algorithm. Further, their execution of chest compressions was assessed pre- and post-intervention. RESULTS: In total, 302 professionals were trained in this study. The overall quality of CPR measured pre-intervention was inadequate, and only 26% had adequate technique proficiency, whereas it was 91% (P < 0.01) post-intervention. Of the participants, 95.7% responded to the final evaluation and provided positive comments on the method and their satisfaction with the novel simulation. Of these, 88% considered that repetition of the technique used was more effective than traditional simulation. CONCLUSIONS: The RCDP is effective for training multidisciplinary teams in pediatric CPR, with an emphasis on the quality of chest compressions. However, further studies are necessary to explore whether this trend translates to differential performances in practical settings.

Chitosan-Based Scaffolds for the Treatment of Myocardial Infarction: A Systematic Review.

Cardiovascular diseases (CVD), such as myocardial infarction (MI), constitute one of the world's leading causes of annual deaths. This cardiomyopathy generates a tissue scar with poor anatomical properties and cell necrosis that can lead to heart failure. Necrotic tissue repair is required through pharmaceutical or surgical treatments to avoid such loss, which has associated adverse collateral effects. However, to recover the infarcted myocardial tissue, biopolymer-based scaffolds are used as safer alternative treatments with fewer side effects due to their biocompatibility, chemical adaptability and biodegradability. For this reason, a systematic review of the literature from the last five years on the production and application of chitosan scaffolds for the reconstructive engineering of myocardial tissue was carried out. Seventy-five records were included for review using the "preferred reporting items for systematic reviews and meta-analyses" data collection strategy. It was observed that the chitosan scaffolds have a remarkable capacity for restoring the essential functions of the heart through the mimicry of its physiological environment and with a controlled porosity that allows for the exchange of nutrients, the improvement of the electrical conductivity and the stimulation of cell differentiation of the stem cells. In addition, the chitosan scaffolds can significantly improve angiogenesis in the infarcted tissue by stimulating the production of the glycoprotein receptors of the vascular endothelial growth factor (VEGF) family. Therefore, the possible mechanisms of action of the chitosan scaffolds on cardiomyocytes and stem cells were analyzed. For all the advantages observed, it is considered that the treatment of MI with the chitosan scaffolds is promising, showing multiple advantages within the regenerative therapies of CVD.

Evidence of the Cardioprotective Effects of Aloysia polystachya in Isoproterenol-Induced Myocardial Infarction in Rats.

Aloysia polystachya is a plant species that is widely used in Brazilian folk medicine for the treatment of different disorders that affect the cardiovascular system. The aim of the study was to investigate the cardioprotective effects of an ethanol-soluble fraction of A. polystachya (ESAP) on isoproterenol-induced myocardial infarction in rats. Different groups of rats (n = 8) were orally treated with ESAP (30, 100, and 300 mg/kg), carvedilol (10 mg/kg), or vehicle (filtered water; 1 mL/100 g) for 7 days. Naive rats received no treatment. On the morning of day 6, acute myocardial infarction was induced by the acute oral administration of isoproterenol (100 mg/kg). On the morning of day 8, all rats underwent electrocardiography and transthoracic echocardiography. Blood samples were then collected, and serum levels of creatine kinase-MB fraction (CK-MB) and cardiac troponin T (cTNT) were quantified. ESAP significantly reduced electrocardiographic changes, improved the ventricular ejection fraction, and reduced serum levels of CK-MB and cTNT in infarcted rats. The cardioprotective effects of ESAP could be exploited as an effective tool against isoproterenol-induced myocardial infarction in rats.

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.

Therapeutic Feasibility of the Natural Products in the Heart Complaints: An Overview.

Heart pain is the most frequent complaint leading patients to seek medical help. Functional heart symptoms, especially chest pain, are prevalent and, according to the International Classification of Diseases (ICD-10), are described as "somatoform autonomous functional disorders of the cardiovascular system." The problem lies in the fact that pain does not always have a somatic background, that is, it may be related to crucial underlying heart disease. The population does not know how to differentiate somatic pain from significant ischemic symptoms, and based on the patient's complaints, traditional medicine ends up treating other underlying cardiac diseases. Many unsuccessful unconventional therapies have been proposed in recent years, including herbal medicines that seek to disrupt the disease's pathogenesis. The present review summarizes research carried out in the last 5 years on natural products' heart complaints, including myocardial ischemia, arrhythmia, and heart failure. Several herbal medicines may be used as a replacement or complementary treatment strategy. A total of 17 medicinal plants have shown promising results in preclinical studies. However, human clinical trials are scarce; only two have been presented. Generally, the data are bland, and many issues have been raised about herbal therapies' safety, efficacy, and mode of action. Besides, relevant clinical trials, future perspectives, and possible clinical applications are discussed.

Its elevation six hours after the procedure is an independent predictor for this complication(AU)

Emergency Care Sensitive Conditions in Brazil: A Geographic Information System Approach to Timely Hospital Access.

Background: The benefits of treatment for many conditions are time dependent. The burden of these emergency care sensitive conditions (ECSCs) is especially high in low- and middle-income countries. Our objective was to analyze geospatial trends in ECSCs and characterize regional disparities in access to emergency care in Brazil. Methods: From publicly available datasets, we extracted data on patients assigned an ECSC-related ICD-10 code and on the country's emergency facilities from 2015-2019. Using ArcGIS, OpenStreetMap, and WorldPop, we created catchment areas corresponding to 180 minutes of driving distance from each hospital. We then used ArcGIS to characterize space-time trends in ECSC admissions and to complete an Origin-Destination analysis to determine the path from household to closest hospital. Findings: There were 1362 municipalities flagged as "hot spots," areas with a high volume of ECSCs. Of those, 69.7% were more than 180 minutes (171 km) from the closest emergency facility. These municipalities were primarily located in the states of Minas Gerais, Bahia, Espiríto Santo, Tocantins, and Amapá. In the North region, only 69.1% of the population resided within 180 minutes of an emergency hospital. Interpretations: Significant geographical barriers to accessing emergency care exist in certain areas of Brazil, especially in peri-urban areas and the North region. One limitation of this approach is that geolocation was not possible in some areas and thus we are likely underestimating the burden of inadequate access. Subsequent work should evaluate ECSC mortality data. Funding: This study was funded by the Duke Global Health Institute Artificial Intelligence Pilot Project.

Predictive Value of Sirtuins in Acute Myocardial Infarction - Bridging the Bench to the Clinical Practice.

Acute myocardial infarction (AMI) is a non-transmissible condition with high prevalence, morbidity, and mortality. Different strategies for the management of AMI are employed worldwide, but its early diagnosis remains a major challenge. Many molecules have been proposed in recent years as predictive agents in the early detection of AMI, including troponin (C, T, and I), creatine kinase MB isoenzyme, myoglobin, heart-type fatty acid-binding protein, and a family of histone deacetylases with enzymatic activities named sirtuins. Sirtuins may be used as predictive or complementary treatment strategies and the results of recent preclinical studies are promising. However, human clinical trials and data are scarce, and many issues have been raised regarding the predictive values of sirtuins. The present review summarizes research on the predictive value of sirtuins in AMI. We also briefly summarize relevant clinical trials and discuss future perspectives and possible clinical applications.

Seventy-five years of cardiovascular rehabilitation in Mexico.

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.

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 diseñados 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.

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.
