ABSTRACT

Abstract Sudden cardiac death is a common occurrence. Out-of-hospital cardiac arrest is a global public health problem suffered by ≈3.8 million people annually. Progress has been made in the knowledge of this disease, its prevention, and treatment; however, most events occur in people without a previous diagnosis of heart disease. Due to its multifactorial and complex nature, it represents a challenge in public health, so it led us to work in a consensus to achieve the implementation of cardioprotected areas in Mexico as a priority mechanism to treat these events. Public access cardiopulmonary resuscitation (CPR) and early defibrillation require training of non-medical personnel, who are usually the first responders in the chain of survival. They should be able to establish a basic and efficient CPR and use of the automatic external defibrillator (AED) until the emergency services arrive at the scene of the incident. Some of the current problems in Mexico and alternative solutions for them are addressed in the present work.


Resumen La muerte súbita cardíaca (SCD) es un acontecimiento común. El paro cardiaco extrahospitalario (OHCA) es un problema de salud pública mundial que sufren ≈3.8 millones de personas al año. Se ha avanzado en el conocimiento de esta enfermedad, su prevención y tratamiento, sin embargo, la mayoría de los eventos se producen en personas sin diagnóstico previo de cardiopatía. Debido a su carácter multifactorial y complejo, representa un reto en salud pública, lo que obliga a trabajar en un consenso para lograr la implementación de "Espacios Cardio protegidos" en México, como mecanismo prioritario de atención a estos eventos. La reanimación cardiopulmonar básica (RCPB) y la desfibrilación temprana de acceso público requieren de entrenamiento al personal no médico, que suelen ser los primeros respondientes para iniciar la cadena de la supervivencia. Ellos deberían instaurar una RCPB eficiente y el uso del desfibrilador automático externo (AED) hasta que lleguen al lugar del incidente los servicios de emergencias. El presente trabajo menciona algunos de los problemas actuales en México y algunas opciones de solución para los mismos.

ABSTRACT

Important forensic diagnostic indicators of sudden death in coronary atherosclerotic heart dis-ease,such as acute or chronic myocardial ischemic changes,sometimes make it difficult to locate the ischemic site due to the short death process,the lack of tissue reaction time.In some cases,the de-ceased died of sudden death on the first-episode,resulting in difficulty for medical examiners to make an accurate diagnosis.However,clinical studies on coronary instability plaque revealed the key role of coronary spasm and thrombosis caused by their lesions in sudden coronary death process.This paper mainly summarizes the pathological characteristics of unstable coronary plaque based on clinical medi-cal research,including plaque rupture,plaque erosion and calcified nodules,as well as the influencing factors leading to plaque instability,and briefly describes the research progress and technique of the atherosclerotic plaques,in order to improve the study on the mechanism of sudden coronary death and improve the accuracy of the forensic diagnosis of sudden coronary death by diagnosing different patho-logic states of coronary atherosclerotic plaques.

ABSTRACT

Objective:To summarize the experience and effect of extracorporeal cardiopulmonary resuscitation (ECPR) on the treatment of sudden cardiac death (SCD).Methods:The data of 120 adults with SCD-ECPR in emergency department of the first affiliated hospital of Nanjing Medical University from April 2015 to April 2023 were retrospectively analyzed. The patients were grouped by Survival/death at 90 days, OHCA/IHCA (out-of-hospital/in-hospital cardiac arrest), with/without acute myocardial infarction (AMI) and divided according to 60 min of the time from cardiac arrest to extracorporeal membrane oxygenation (ECMO) initiation (CA-Pump On time). Age, sex, Charlson comorbidity index, IHCA/OHCA, initial rhythm, no-flow time, CA-Pump On time, ECMO evacuation success rate, 90-day survival rate, ECMO treatment time were analyzed.Results:①Total of 114 adult patients with SCD-ECPR were enrolled, and 45 (39.5%) patients survived at 90 days, of whom 40 (88.9%) patients had good neurological outcomes.②Age and no-flow time were significantly lower in the 90-day survival group than that in death group, and the proportion of IHCA and shockable initial rhythm was higher. ③The no flow time in IHCA group was significantly lower than that in OHCA group, and the 90-day survival rate was higher. ④OHCA and regional interhospital transport prolonged CA-Pump On time and reduced the 90-day survival rate. ⑤The AMI group was older with a higher Charlson comorbidity index, and the 90-day survival rate was significantly lower than that in non-AMI group.Conclusions:ECPR improves the prognosis of patients with SCD, there are high benefits in patients with long healthy life expectancy, IHCA, shockable initial rhythm, and short no flow time. The smooth life-saving chain of SCD-ECPR improves survival rate, by screening high benefit candidates in patients with OHCA, delayed initiation of ECPR or requiring interhospital transport, despite CA-Pump On time > 60 min, there is still survival potential.

ABSTRACT

SUMMARY OBJECTIVE: Sudden cardiac death or arrest describes an unexpected cardiac cause-related death or arrest that occurs rapidly out of the hospital or in the emergency room. This study aimed to reveal the relationship between coronary angiographic findings and cardiac death secondary to acute ST-elevation myocardial infarction. MATERIALS AND METHODS: Patients presenting with acute ST-elevation myocardial infarction complicated with cardiac arrest were included in the study. The severity of coronary artery disease, coronary chronic total occlusion, coronary collateral circulation, and blood flow in the infarct-related artery were recorded. Patients were divided into two groups, namely, deaths secondary to cardiac arrest and survivors of cardiac arrest. RESULTS: A total of 161 cardiac deaths and 42 survivors of cardiac arrest were included. The most frequent (46.3%) location of the culprit lesion was on the proximal left anterior descending artery. The left-dominant coronary circulation was 59.1%. There was a difference in the SYNTAX score (16.3±3.8 vs. 13.6±1.9; p=0.03) and the presence of chronic total occlusion (19.2 vs. 0%; p=0.02) between survivors and cardiac deaths. A high SYNTAX score (OR: 0.38, 95%CI: 0.27-0.53, p<0.01) was determined as an independent predictor of death secondary to cardiac arrest. CONCLUSION: The chronic total occlusion presence and SYNTAX score may predict death after cardiac arrest secondary to ST-elevation myocardial infarction.

ABSTRACT

Cardiac arrest (CA) resulting from sudden cardiac death and acute coronary syndromes affects many people every day all over the world. Post-cardiac arrest syndrome (PCAS) encompasses post-CA brain injury, myocardial dysfunction, reperfusion injury, and the continuation of the causative event, as a complex and critical issue that requires multidisciplinary intervention. Successful intervention in these cases can only be achieved with advanced cardiac life support (ACLS) management to provide the return of spontaneous circulation (ROSC). Favorable neurological outcome targets have been established in recent decades and some progress has been made despite many uncertainties still exist. Optimization of oxygenation and hemodynamics, early coronary interventions, ACLS, and early and intensive management of targeted temperature management (TTM) has been reported to positively affect survival with fewer neurological sequelae in patients with ROSC. Institution of extracorporeal cardiopulmonary resuscitation (eCPR) initiated within 50 min of collapse, and combination of TTM with eCPR were advocated as predictors of favorable prognosis. In this study, efforts to provide the best outcomes after CA and related advances are described.

ABSTRACT

Resumen Introducción: El desfibrilador automático implantable (DAI) transvenoso es el tratamiento de elección para la prevención de muerte súbita (MS) cardiaca por arritmias ventriculares malignas. Su uso se puede ver limitado cuando existe infección del sistema de estimulación o en población pediátrica donde representa un reto por diversas razones, incluyendo: las mínimas dimensiones del sistema venoso de los niños, la longitud de los electrodos, el tamaño del generador, así como por la complejidad anatómica en casos de cardiopatía congénita asociada. Objetivo: El presente artículo tiene por objetivo presentar la primera serie de casos de pacientes mexicanos a los cuales se les implantó un DAI subcutáneo (DAI-SC) como terapia para la prevención de MS. Métodos: Se presentan los cuatro primeros casos que fueron implantados en el Instituto Nacional de Cardiología Ignacio Chávez con un DAI-SC (Emblem, Boston Scientific, EE.UU.), tres de ellos eran pacientes pediátricos, incluyendo el primer implante de este tipo de dispositivo en un paciente pediátrico en América Latina. Las técnicas de tres y dos incisiones fueron empleadas bajo anestesia general. Resultados: Se realizó el implante exitoso con técnica de tres incisiones en los dos primeros casos y con técnica de dos incisiones en los dos últimos casos. Se corroboró el adecuado funcionamiento del dispositivo en sala, con la verificación de terapia apropiada (65 J) de la fibrilación ventricular inducida mediante estimulación a 50 Hz. No hubo complicaciones inmediatas. Un paciente presentó descargas apropiadas a los dos meses del implante. En el seguimiento, un niño desarrolló erosión de la piel a nivel de la curva del electrodo en el esternón, sin datos de infección. En quirófano se resecó la piel dañada, se retiró el barril y la seda de fijación, se realizó lavado quirúrgico y se volvió a cerrar la piel, logrando así evitar el retiro del sistema. Conclusiones: El DAI-SC es una terapia alternativa al DAI endovenoso y puede ser considerado de primera elección en aquellos casos que no requieran de estimulación ventricular, incluyendo pacientes pediátricos. Pueden ocurrir complicaciones cutáneas, pero no representan una amenaza como las complicaciones venosas de los DAI convencionales.


Abstract Introduction: The transvenous implantable cardioverter defibrillator (ICD) is the treatment of choice for the prevention of sudden cardiac death (SCD). Its use could be restricted when device-related infections occurs or in the pediatric population. In the later, an ICD represents a challenge, due to the minimal dimensions of the venous system in children, the length of the electrodes, the size of the generator, as well as the anatomical complexity in cases with associated congenital heart disease. Objective: This article presents the first Mexican patients with a subcutaneous ICD (SC-ICD) implant as a therapy for the prevention of SCD. Methods: The first four cases were implanted at the Ignacio Chávez National Institute of Cardiology with a SC-ICD (Emblem, Boston Scientific, USA), three of them were pediatric patients, including the first implant of this type of device in a pediatric patient in Latin America. The 3-incision and 2-incision techniques were used under general anesthesia. Results: A successful implantation was obtained with the 3-incision technique in the first 2 cases and the last 2 with the 2-incision technique. Proper functioning of the device was corroborated in the operating room with proof of appropriate therapy (65 J) for ventricular fibrillation induced with 50 Hz stimulation. No immediate complications were observed. One patient had appropriate shocks two months after the implant. During follow-up, one child developed skin erosion at the level of the curve of the electrode on the sternum, with no signs of infection. In the operating room, the damaged skin was resected, the barrel and the fixation silk were removed, surgical lavage was performed, and the skin was closed again, thus avoiding removal of the system. Conclusions: The SC-ICD is an alternative therapy to the transvenous ICD. It can be considered first choice in subjects who do not require ventricular pacing, including pediatric patients. Skin complications can occur but do not pose a threat as venous complications of conventional ICDs.

ABSTRACT

Introducción: La miocardiopatía hipertrófica (MCH) constituye una enfermedad compleja y variable en cuanto a morfología, fisiopatología, pronóstico y sobrevida. Se caracteriza por una hipertrofia del ventrículo izquierdo, aunque en ocasiones puede ser biventricular o ventricular derecha aislada. En la edad pediátrica predominan las causas no sarcoméricas. La ecocardiografía es el método diagnóstico más utilizado para caracterizar la morfología y repercusión hemodinámica, sin embargo, la resonancia magnética cardíaca (RMC) es de elección por aportar mayores ventajas morfológicas y funcionales. Las pruebas genéticas son de gran importancia en la determinación del diagnóstico etiológico, manejo terapéutico y pronóstico. El tratamiento tiene como objetivo principal mejorar la capacidad funcional y aliviar los síntomas. Los betabloqueantes no vasodilatadores son considerados de primera líneay en algunos casos se puede recurrir a terapias avanzadas como disopiramida o terapia de reducción septal (TRS), uso del cardiodesfibrilador implantable (CDI), y en ocasiones se debe considerar trasplante cardiaco en pacientes con síntomas refractarios al tratamiento médico y en MCH del tipo obstructivo. Materiales y métodos: Estudio observacional, descriptivo, corte transversal. Resultados: Se estudiaron 12 pacientes, desde enero de 2020 a diciembre de 2022, con edades comprendidas desde 5 meses hasta 16 años, diagnosticados con MCH de presentación clínica variable y de distintas etiologías. Conclusión: La MCH de causas no sarcoméricas como los síndromes malformativos y errores innatos del metabolismo son las que tienen peor pronóstico y sobrevida. La finalidad de detectar precozmente la MCH es el inicio temprano de la terapia específica, para así retrasar el compromiso cardiovascular y mejorar la sobrevida.


Introduction: Hypertrophic cardiomyopathy (HCM) is a complex and variable disease in terms of morphology, pathophysiology, prognosis and survival. It is characterized by left ventricular hypertrophy, although it can sometimes be biventricular or isolated right ventricular. In the pediatric population, non-sarcomeric causes predominate. Echocardiography is the most widely used diagnostic method to characterize morphology and hemodynamic repercussions; however, cardiac magnetic resonance imaging (CMR) is preferred because it provides greater morphological and functional advantages. Genetic tests are of great importance in determining the etiological diagnosis, therapeutic management and prognosis. The main objective of the treatment is to improve functional capacity and alleviate symptoms. Non-vasodilator beta-blockers are considered first-line treatment and in some cases advanced therapies such as disopyramide or septal reduction therapy (SRT), use of implantable cardioverter-defibrillator (ICD) can be used; heart transplantation should be considered in patients with symptoms refractory to medical treatment and in HCM of the obstructive type. Materials and methods: This was an observational, descriptive, cross-sectional study. Results: 12 patients were studied, from January 2020 to December 2022, with ages ranging from 5 months to 16 years, diagnosed with HCM of variable clinical presentation and of different etiologies. Conclusion: HCM from non-sarcomeric causes such as malformation syndromes and inborn errors of metabolism have the worst prognosis and survival. The purpose of early detection of HCM is the early initiation of specific therapy, in order to delay cardiovascular compromise and improve survival.

ABSTRACT

Background & Objective: Despite the burden of sudden cardiac arrest (SCA) worldwide, implantable cardioverter-defibrillators (ICDs) are underutilized, particularly in Asia, Latin America, Eastern Europe, the Middle East, and Africa. The Improve SCA trial demonstrated that primary prevention (PP) patients in these regions benefit from an ICD or a cardiac resynchronization therapy defibrillator (CRT-D). We aimed to compare the rate of device therapy and mortality among ischemic and non-ischemic cardiomyopathy (ICM and NICM) PP patients who met guideline indications for ICD therapy and had an ICD/CRT-D implanted. Methods: Improve SCA was a prospective, non-randomized, non-blinded multicenter trial that enrolled patients from the above-mentioned regions. All-cause mortality and device therapy were examined by cardiomyopathy (ICM vs NICM) and implantation status. Cox proportional hazards methods were used, adjusting for factors affecting mortality risk. Results: Of 1848 PP NICM patients, 1007 (54.5%) received ICD/CRT-D, while 303 of 581 (52.1%) PP ICM patients received an ICD/CRT-D. The all-cause mortality rate at 3 years for NICM patients with and without an ICD/CRT-D was 13.1% and 18.3%, respectively (HR 0.51, 95% CI 0.38e0.68, p < 0.001). Similarly, all-cause mortality at 3 years in ICM patients was 13.8% in those with a device and 19.9% in those without an ICD/CRT-D (HR 0.54, 95% CI 0.33e.0.88, p ¼ 0.011). The time to first device therapy, time to first shock, and time to first antitachycardia pacing (ATP) therapy were not significantly different between groups (p 0.263). Conclusions: In this large data set of patients with a guideline-based PP ICD indication, defibrillator device implantation conferred a significant mortality benefit in both NICM and ICM patients. The rate of appropriate device therapy was also similar in both groups.

ABSTRACT

Objective:To describe the clinical features and prognosis of congenital anomalous origin of coronary artery(AOCA) in children to increase our understanding of the disease.Methods:This retrospective study included children diagnosed with AOCA using computed tomography coronary angiography(CTCA) admitted to the Department of Cardiology, Beijing Children′s Hospital, Capital Medical University, from January 1, 2014 to December 31, 2019.The clinical presentations, laboratory results, imaging analyses, treatments, and prognoses of these patients were analyzed.Results:A total of 208 children, including 105 boys and 103 girls, we evaluated the ages(9.03±4.18)years old with AOCA.Of these, 157 cases(75.5%) presented with cardiac symptoms, such as chest tightness, palpitations, dizziness, syncope, fatigue, and decreased endurance.Three cases(1.4%) had atypical symptoms of paroxysmal crying, dyspnoea and cyanosis, and 48 cases(23.1%) were asymptomatic.Levels of serological markers of myocardial injury were elevated in 59 cases(28.4%), and 140 cases(67.3%) had predominant ST-T abnormalities on electrocardiograms.Transthoracic echocardiography identified 27 cases (13%) with cardiac enlargement and ten cases(4.8%) with left ventricular systolic dysfunction.There were 126 cases(60.6%) with the anomalous origin of the left coronary artery revealed by CTCA, 50 cases(24.0%) with the anomalous origin of the right coronary artery and 32 cases(15.4%) with bilateral coronary arteries of anomalous origin.Five children underwent surgical treatment, and the remaining 203 children were treated conservatively with drugs.The whole group was successfully treated, and no death case was recorded during the follow-up period.Conclusion:AOCA may cause different degrees of myocardial ischemia.Diverse clinical presentations and diagnostic limitations of transthoracic echocardiography often lead to missed diagnosis or misdiagnosis.In contrast, CTCA has high diagnostic accuracy and can be used to identify the location and course of the coronary ostia.Hence, the management of AOCA should be tailored on a case-to-case basis, taking into consideration of the specific type of coronary origin, with surgical intervention being warranted if necessary.

ABSTRACT

OBJECTIVES@#To analyze the gross pathological data of sudden cardiac death (SCD) with different causes, to provide data support for the identification of sudden cardiac death with unknown causes.@*METHODS@#A total of 167 adult SCD cases in the archive of the Forensic Expertise Institute of Nanjing Medical University from 2010 to 2020 were collected. The gross pathological data of SCD cases were summarized and the characteristics of different causes of death were statistically analyzed.@*RESULTS@#The ratio of male to female SCD cases was 3.4∶1. Coronary heart disease was the leading cause of SCD, and mainly distributed in people over 40 years old. SCD caused by myocarditis was mainly distributed in young people and the mean age of death was (34.00±9.55) years. By analyzing the differences in cardiac pathological parameters of SCD with different causes, it was found that the aortic valve circumference was significantly dilated in the SCD caused by aortic aneurysm or dissection (P<0.05). The heart weight of SCD caused by aortic aneurysm or dissection and combined factors was greater, and both pulmonary and tricuspid valvular rings were dilated in the SCD caused by combined factors in adult males (P<0.05).@*CONCLUSIONS@#Various gross pathological measures of SCD with different causes are different, which has reference value in the cause of death identification of SCD.

ABSTRACT

Resumo Fundamento A ressonância magnética cardíaca (RMC) tem relevância diagnóstica crescente em sobreviventes de morte súbita cardíaca (MSC) ou arritmia ventricular instável (AVI) em países desenvolvidos. Objetivo Procuramos avaliar retrospectivamente o papel adicional da RMC em um país em desenvolvimento com poucos recursos disponíveis e que pode direcionar um uso mais eficaz desses recursos. Métodos Foram incluídos sobreviventes de MSC ou AVI admitidos entre 2009 e 2019 em uma instituição acadêmica terciária após a realização de RMC. Dados demográficos, clínicos e laboratoriais foram coletados dos prontuários. Imagens e laudos de RMC foram analisados e o impacto disso no diagnóstico etiológico final foi afirmado. Realizou-se análise descritiva e definiu-se p<0,05 como significativo. Resultados Sessenta e quatro pacientes, 54,9±15,4 anos, sendo 42 (71,9%) do sexo masculino. A maioria dos eventos (81,3%) foi extra-hospitalar e a taquicardia ventricular foi o ritmo mais comum. Medicamentos cardiovasculares foram utilizados anteriormente por 55 pacientes, sendo os betabloqueadores os medicamentos mais utilizados (37,5%). O eletrocardiograma apresentava áreas elétricas inativas em 21,9% e todos apresentavam fibrose na RMC. A média da fração de ejeção do ventrículo esquerdo (FEVE) foi de 44±14%, com 60,9% ≤50% e apenas 29,7% ≤35%. Identificou-se realce tardio com gadolínio em 71,9%, com padrão transmural em 43,8%. A miocardiopatia chagásica foi a etiologia mais comum (28,1%), seguida da miocardiopatia isquêmica (17,2%). Entre 26 sem etiologia previamente identificada, foi possível definir com RMC (15 pacientes - 57%). Conclusão De acordo com estudos anteriores em países desenvolvidos, a RMC foi capaz de aumentar o diagnóstico etiológico e identificar o substrato arritmogênico, permitindo melhor atendimento em metade dos pacientes subdiagnosticados.


Abstract Background Cardiac magnetic resonance (CMR) has an increasing diagnostic relevance in survivors of sudden cardiac death (SCD) or unstable ventricular arrhythmia (UVA) in developed countries. Objective To evaluate retrospectively the additional role of CMR in a developing country where few resources are available, and should be used more effectively. Methods The study included SCD or UVA survivors admitted between 2009 and 2019 at a tertiary academic institution referred to CMR. Demographic, clinical, and laboratory data were collected from the medical records. CMR images and reports were reviewed and their impact on the final etiological diagnosis was determined. A descriptive analysis was performed and p<0.05 established as significant. Results Sixty-four patients, 54.9±15.4 years old, and 42 (71.9%) males. Most events (81.3%) were out of the hospital and ventricular tachycardia was the most common rhythm. Cardiovascular medications were previously used by 55 patients, and beta-blockers were the most used medications (37.5%). Electrocardiogram had electrical inactive areas in 21.9% and all of them had fibrosis at CMR. Mean left ventricular ejection fraction (LVEF) was 44±14%, with 60.9% ≤50% and only 29.7% ≤35%. Late gadolinium enhancement was identified in 71.9%, with a transmural pattern in 43.8%. Chagas cardiomyopathy was the most common etiology (28.1%), followed by ischemic cardiomyopathy (17.2%). Among 26 without a previously identified etiology, CMR could define it (15 patients - 57%). Conclusion In accordance with previous studies in developed countries, CMR was capable of increasing etiological diagnosis and identifying the arrhythmogenic substrate, allowing better care in half of the underdiagnosed patients.

ABSTRACT

Introducrion: although the mortality rate among soccer players is low, it causes much impact on the entire community and is a fascinating conundrum. Objetive: to evaluate the cardiovascular risk of soccer referees, to describe the frequency of cardiovascular risk considering age groups younger and older than 35 years old and to relate the Framingham and PROCAM indices for the comparison of cardiovascular risk in soccer referees. Methods: We analyzed 50 referees of Paulista Soccer Federation subjected to clinical and laboratory based evaluations at the Center for Sports Health at the Faculty of Medicine of ABC, and were divided into two groups: lower and higher than 35 years of age. For analysis involving all variables of the study it was initially carried out as a descriptive evaluation of the entire group, and then the Framingham and PROCAM methods were applied in a two-dimensional way. Finally, the logistic regression analysis was applied. Anthropometric statistics, blood pressure, laboratory tests and ergospirometric values were within normal limits. Results: referees older than 35 years old presented significant increased values of waist circumference, body mass index, glucose blood levels, lower VO2max and higher cardiovascular risk according to Framingham and PROCAM. Conclusion: the risk for coronary heart disease was higher in referees older than 35 years old.

ABSTRACT

SUMMARY OBJECTIVE: This study aimed to evaluate the agreement in the indication of implantable cardioverter-defibrillators in patients with Hypertrophic cardiomyopathy, as per the 2014 European Society of Cardiology and 2020 American Heart Association recommendations, and evaluate fragmented QRS as a predictor of cardiovascular outcome. METHODS: Retrospective cohort with 81 patients was evaluated between 2019 and 2021. Patients with hypertrophic cardiomyopathy ≥16 years old were included. Exclusion criteria include secondary myocardiopathy and follow-up <1 year. Kappa coefficient was used to determine the agreement. Survival and incidence curves were determined by Kaplan-Meier method. A p<0.05 was considered significant. RESULTS: The fragmented QRS was identified in 44.4% of patients. There were no differences between patients with and without fragmented QRS regarding clinical parameters, echocardiography, fibrosis, and sudden cardiac death risk. During follow-up of 4.8±3.4 years, there was no sudden cardiac death, but 20.6% patients with implantable cardioverter-defibrillator had at least one appropriate shock. Three of the seven appropriate shocks occurred in European Society of Cardiology low- to moderate-risk patients. Three shocks occurred in moderate-risk patients and four in American Heart Association high-risk patients. Overall recommendations agreement was 64% with a kappa of 0.270 (p=0.007). C-statistic showed no differences regarding the incidence of appropriate shock (p=0.644). CONCLUSION: sudden cardiac death risk stratification algorithms present discrepancies in implantable cardioverter-defibrillator indication, both with low accuracy.

ABSTRACT

Introducción: El objetivo de este estudio fue sintetizar la evidencia sobre las causas de muerte súbita cardiaca (MSC) asociada a hipokalemia en individuos de ≥15 a <65 años de edad sin cardiopatía estructural. Reporte de caso. Reportamos un caso y recopilamos casos de MSC siguiendo la estrategia PECO. Realizamos una búsqueda bibliográfica hasta el 30 de noviembre del 2021. Incluimos 25 casos. La edad media fue 33,8 ± 2,4 años. Del total de casos, 60% fueron varones y 60% correspondieron a etiologías adquiridas. La tirotoxicosis fue la etiología del 8% de casos. El intervalo QTc estuvo prolongado en 90% de casos en los que se pudo registrar. El 60% de casos fueron extrahospitalarios. Solo el 24% de los episodios resultaron en muerte. Conclusiones. La tirotoxicosis es una causa rara de parada cardiaca súbita (PCS) hipokalémica. La PCS parece asociarse a mejores clínicos comparada con la PCS asociada a kiperkalemia o normokalemia.


Introduction: The aim of this study was to synthesize the evidence on the causes of sudden cardiac death (SCD) associated with hypokalemia in individuals ≥15 to <65 years of age without structural heart disease. Case report. We reported a case and collected SCD cases following the PECO strategy. We conducted a bibliographic search of the literature published up to November 30, 2021. We included 25 cases. The mean age was 33.8 ± 2.4 years. Of the total cases, 60% were male and 60% corresponded to acquired etiologies. Thyrotoxicosis was the etiology of 8% of cases. The QTc interval was prolonged in 90% of the cases in which it could be recorded. Sixty percent of cases occurred out of hospital. Only 24% of episodes resulted in death. Conclusions. Thyrotoxicosis is a rare cause of hypokalemic sudden cardiac arrest (SCA). Hypokalemic SCA seems to be associated with better clinical results compared to SCA associated with hyperkalemia or normokalemia.

ABSTRACT

RESUMEN Introducción: La muerte súbita cardiaca es un resultado poco común siendo en adolescentes incluso más catastrófico tanto para su entorno familiar como la sociedad, por lo cual es de vital importancia identificar los factores que pueden conllevar a una persona estar en riesgo de tener esta devastadora muerte. Objetivo: Determinar los factores de riesgo de muerte súbita cardiaca en adolescentes. Metodología: Se realizó una revisión sistemática donde se tomaron en cuenta todos los artículos en el idioma inglés y español los cuales fueron publicados desde el año 2020 hasta el año 2021, en los sitios de búsqueda PubMed y Google Scholar. Se utilizó la siguiente pregunta PEO: Población: Adolescentes, Exposición: Factores de riesgo, Outcome: Muerte súbita cardiaca. Las palabras clave fueron: "youth", en combinación con "Risk Factors" y "Sudden Cardiac Death" (utilizados en PubMed). En Google Scholar se utilizaron los siguientes términos para la búsqueda avanzada: "Adolescentes", "Muerte súbita Cardiaca" y "Factores de riesgo". Se seleccionaron los artículos publicados desde el año 2015 que cumplieran con los criterios de exclusión. Resultados: De los 13 artículos para esta revisión con respecto a la muerte súbita cardiaca en adolescentes se encontró una variedad de causas o factores de riesgo que hicieron desencadenar esta patología encontrando entre estas ciertas causantes con mayor repetición. Conclusión: La muerte súbita cardiaca tiene como principales factores de riesgo a las cardiopatías congénitas y la carga genética; los cuales debemos identificar y así poder actuar de una manera preventiva disminuyendo su incidencia de muerte.


ABSTRACT Introduction: Sudden cardiac death is an uncommon result, being in adolescents even more catastrophic for both their family environment and society, for which it is vitally important to identify the factors that can lead a person to be at risk of having this devastating death. Objective: To determine the risk factors for sudden cardiac death in adolescents. Methods: A systematic review was carried out where all the articles in English and Spanish were taken into account, which were published from 2020 to 2021, on the PubMed and Google Scholar search sites. The following PEO question was used: Population: Adolescents, Exposure: Risk factors, Outcome: Sudden cardiac death. The keywords were: "youth", in combination with "Risk Factors" and "Sudden Cardiac Death" (used in PubMed). In google scholar, the following terms were used for the advanced search: "Adolescents", "Sudden Cardiac Death" and "Risk factors". Articles published since 2015 that met the exclusion criteria were selected. Results: Of the 13 articles for this review regarding sudden cardiac death in adolescents, a variety of causes or risk factors were found that triggered this pathology, finding among these certain causes with greater repetition. Conclusion: Sudden cardiac death has as main risk factors congenital heart disease and genetic load; which we must identify and thus be able to act in a preventive manner reducing their incidence of deaths.

ABSTRACT

Abstract Background: The risk of sports-related sudden cardiac arrest after COVID-19 infection can be a serious problem. There is an urgent need for evidence-based criteria to ensure patient safety before resuming exercise. Objective: To estimate the pooled prevalence of acute myocardial injury caused by COVID-19 and to provide an easy-to-use cardiovascular risk assessment toolkit prior to resuming sports activities after COVID-19 infection. Methods: We searched the Medline and Cochrane databases for articles on the prevalence of acute myocardial injury associated with COVID-19 infection. The pooled prevalence of acute myocardial injury was calculated for hospitalized patients treated in different settings (non-intensive care unit [ICU], ICU, overall hospitalization, and non-survivors). Statistical significance was accepted for p values <0.05. We propose a practical flowchart to assess the cardiovascular risk of individuals who recovered from COVID-19 before resuming sports activities. Results: A total of 20 studies (6,573 patients) were included. The overall pooled prevalence of acute myocardial injury in hospitalized patients was 21.7% (95% CI 17.3-26.5%). The non-ICU setting had the lowest prevalence (9.5%, 95% CI 1.5-23.4%), followed by the ICU setting (44.9%, 95% CI 27.7-62.8%), and the cohort of non-survivors (57.7% with 95% CI 38.5-75.7%). We provide an approach to assess cardiovascular risk based on the prevalence of acute myocardial injury in each setting. Conclusions: Acute myocardial injury is frequent and associated with more severe disease and hospital admissions. Cardiac involvement could be a potential trigger for exercise-induced clinical complications after COVID-19 infection. We created a toolkit to assist with clinical decision-making prior to resuming sports activities after COVID-19 infection.

ABSTRACT

Objective:To investigate the clinical characteristics and causes of death of chronic Keshan disease cases.Methods:A retrospective analysis was conducted on the last clinical data of 39 death cases of chronic Keshan disease who were repeatedly hospitalized in Jingchuan County People's Hospital from March 2016 to August 2020 before their death, including gender, age, course of disease, clinical symptoms and signs, chest X-ray, electrocardiogram, cardiac echocardiography, causes of death, etc., and analysis was made on the clinical characteristics related to the death of chronic Keshan disease cases.Results:Among the 39 death cases of chronic Keshan disease, 27 cases (69.2%) were male and 12 cases (30.8%) were female. The age was (62.64 ± 8.63) years old, and the median course of disease was 5 years. Dyspnea [37 cases (94.9%)] and edema [33 cases (84.6%)] were the main clinical symptoms. All cases had varying degrees of cardiac enlargement, pulmonary congestion signs, and abnormal changes in electrocardiogram. Among the causes of death, 18 cases (46.2%) were sudden cardiac death, 11 cases (28.2%) were heart failure, 5 cases (12.8%) were cardiogenic shock, and 3 cases (7.7%) were heart failure combined with cardiogenic shock, and 2 cases (5.1%) had other causes.Conclusion:Dyspnea and edema are the main clinical characteristics of death cases of chronic Keshan disease, sudden cardiac death, heart failure and cardiogenic shock are the three common causes of death.

ABSTRACT

Exosomal microRNAs (miRNAs) are miRNAs that are mediated by exosomes to achieve cell-to-cell communication, and they are widespread in organisms. In recent years, the key role of the multiple biological functions of exosomal miRNAs in the occurrence and development of cardiovascular diseases has been confirmed by a large number of studies, which has become a hot spot in clinical and basic research. Sudden cardiac death caused by cardiovascular disease is one of the important contents in forensic medical identification. This article introduces the research progress of cardiovascular disease prediction, treatment and prognosis on exosomal miRNA. The prospects of the application in forensic medical identification are discussed.
