RESUMO
A cardiomiopatia hipertrófica (CMH) é uma forma relativamente comum e complexa de doença cardíaca genética, sendo considerada a maior causa de morte súbita (MS) cardíaca em pessoas jovens, incluindo atletas, respondendo por 36% dos casos em jovens atletas nos Estados Unidos (EUA). O implante decardioversor-desfibrilador (CDI) tem demonstrado alta eficácia na prevenção desse evento. Para avaliação diagnóstica da CMH, o eletrocardiograma (ECG)representa ferramenta bastante útil, pois se encontra alterado em 75% a 95% dos casos clínicos. Após o implante do CDI, como demonstrado no caso relatado, são observadas variações no ECG que podem explicar a mudança benéfica na fisiopatologia obstrutiva da CMH.
ABSTRACT
Hypertrophic cardiomyopathy (HCM) is a relatively common and complex genetic heart disease, rated as main cause of sudden cardiac death (SCD) in young people, including athletes, accounting for 36% of these cases in young athletes in the United States(USA). IDC implants have proved highly effective for preventing such events. For diagnostic evaluations of CMH, the electrocardiogram (ECG) is a very useful tool, being altered in 75% to 95% of clinical cases. After an ICD implant, as demonstrated in this case report, variations in the ECG are noted that could explain the beneficial alteration in the pathophysiology of obstructive HCM.
