A morte subita em atletas e um evento dramatico e tem sido demonstrado que, na maioria das vezes, se deve a doencas cardiovasculares congenitas ou adquiridas. O objetivo deste artigo e abordar alguns aspectos da cardiomiopatia hipertrofica, que e a principal causa de morte subita em atletas jovens, e sugerir medidas para prevenir essa condicao.
To the Editor: We found the excellent review, “New concepts in hypertrophic cardiomyopathies,”1,2⇓ very stimulating, although in our opinion, one issue needs further clarification in light of existing evidence in the literature (or lack thereof). The authors state (page 2249, first paragraph) that “because the LVOT [left ventricular outflow tract] obstruction is dynamic, patients in whom the disease is suspected and who do not have a gradient at rest should undergo provocation maneuvers with age...
Background. Sudden death from cardiac arrest in a young person may occur during sports play after a blunt blow to the chest in the absence of structural cardiovascular disease or traumatic injury (cardiac concussion or commotio cordis). We studied the clinical features of this apparently uncommon but important phenomenon. Methods. We identified cases from the registries of relevant agencies and organizations, as well as newsmedia accounts, and developed a clinical profile of 25 children and youn...
Background Sudden death is a possible consequence of hypertrophic cardiomyopathy. Quantification of the risk of sudden death, however, remains imprecise for most patients with this disease. Methods We assessed the relation between the magnitude of left ventricular hypertrophy and mortality in 480 consecutive patients with hypertrophic cardiomyopathy. The patients were categorized into five subgroups according to maximal wall thickness: 15 mm or less, 16 to 19 mm, 20 to 24 mm, 25 to 29 mm, and 30...
Las miocardiopatias constituyen un conjunto extraordinariamente heterogeneo de procesos que solo tienen en comun que afectan el musculo cardiaco y que causan un amplio espectro de formas de disfuncion del mismo. El enfoque del manejo y tratamiento de las miocardiopatias es objeto permanente de discusion porque la mayor parte de alternativas en este campo no se han basado en la mejor evidencia cientifica posible, puesto que con la excepcion del tratamiento de la insuficiencia cardiaca en el conte...

Background Hypertrophic cardiomyopathy is a genetic disease associated with a risk of ventricular tachyarrhythmias and sudden death, especially in young patients. Methods We conducted a retrospective multicenter study of the efficacy of implantable cardioverter–defibrillators in preventing sudden death in 128 patients with hypertrophic cardiomyopathy who were judged to be at high risk for sudden death. Results At the time of the implantation of the defibrillator, the patients were 8 to 82 years ...
Although uncommon, sudden cardiac death (SCD) in children and adolescents is a devastating entity that raises anxiety and concerns within the general community. Its specter is heightened by the recent deaths of some elite athletes who were ostensibly healthy and without any risk factors. This article enumerates those entities associated with SCD in children and adolescents and, more importantly, advises general pediatricians and family practitioners as to how children at risk can be identified. ...
Abstract Objectives. We investigated the long-term prognosis of completely asymptomatic adult patients with hypertrophic cardiomyopathy (HC). Diagnosis of HC was suspected because of an abnormal electrocardiogram and/or cardiac murmur and confirmed by echocardiography and/or left ventricular angiography, and hemodynamic investigation. Background. Hypertrophic cardiomyopathy shows marked heterogeneity in clinical expression and prognosis. The prognosis of asymptomatic patients with HC has not bee...
La miocardiopatia hipertrofica es la causa mas comun de muerte subita en pacientes jovenes sin otra patologia. El riesgo de muerte subita es especialmente elevado en pacientes entre los 14 y 35 anos de edad. Los mecanismos involucrados en la muerte subita son varios: arritmias ventriculares, arritmias supraventriculares que producen colapso circulatorio, bradicardias e isquemia severa. Numerosos estudios han analizado los factores que permiten identificar a aquellos pacientes con un riesgo eleva...

Background Myocardial bridging may cause compression of a coronary artery, and it has been suggested that myocardial ischemia may result. The clinical significance and prognostic value of myocardial bridging of the left anterior descending coronary artery in children with hypertrophic cardiomyopathy are unknown. We sought to determine the prevalence and clinical effects of myocardial bridging in children with hypertrophic cardiomyopathy who underwent cardiac catheterization. Methods Angiograms f...
The cardiovascular evaluation is an important component of the preparticipation physical examination of the athlete. The history should be standardized to include questions ranging from those about chest pain and palpitations to ones about syncope. The physical examination should not be a perfunctory one, but rather a careful search for findings that might include a low grade heart murmur that accentuates with Valsalva'a maneuver (suggestive of hypertrophic cardiomyopathy, the leading cause of s...
Background: Sudden cardiac death (SCD) in athletes during physical activity is rare. Objectives: To evaluate the warning signs for SCD in young athletes and correlate them with electrocardiographic data. Methods: This was a case-control, prospective study, and comparing athletes with sedentary individuals. The Sudden Cardiac Death Screening of Risk Factors (SCD-SOS) questionnaire was applied and resting electrocardiography was performed. Results: In total, 898 participants were included, 589 (65...
Introducao: O “coracao de atleta” e definido como uma adaptacao benigna em virtude da atividade fisica, apresentando diâmetros cavitarios e espessuras ventriculares aumentadas. Objetivo: O trabalho objetiva verificar a incidencia de sinais de “coracao de atleta” em judocas, diferenciando da Cardiomiopatia Hipertrofica e identificar o percentual de gordura corporal. Metodo: amostra constituida de 40 judocas de 14 a 24 anos com treinamento minimo de 3 anos. Submetidos a avaliacao antropometrica, p...
A morte subita que ocorre com o atleta, durante a atividade fisica, e um evento raro, mas que causa grande impacto na populacao sempre que e divulgada na midia. Isso traz um questionamento importante: o exercicio e sinonimo de saude ou de risco para morte? E a resposta e que ele simboliza saude, sempre que bem praticado e representa risco quando praticado erroneamente e por atletas com doencas cardiacas previamente estabelecidas. Nos atletas com menos de 35 anos de idade, a principal doenca rela...
