ABSTRACT

Summary Although myocardial rupture occurs in only 2% to 4% of cases of acute myocardial infarction (AMI), there is a high mortality rate due to acute cardiogenic shock. We present the anatomopathological findings of three cases of myocardial rupture in autopsied hearts in the last 30 years, with a diagnosis of cardiac rupture in acute myocardial infarction. In these 30 years the percentage of AMI with myocardial rupture was 0.2%. Risk factors for post-AMI myocardial rupture include older age, atherosclerosis, diabetes mellitus and systemic arterial hypertension.


Resumo Embora a ruptura do miocárdio ocorra em apenas 2 a 4% dos casos de infarto agudo do miocárdio (IAM), está associada a alta mortalidade, principalmente em decorrência do estado de choque cardiogênico agudo. São apresentados os achados anatomopatológicos de três casos de ruptura do miocárdio de pacientes autopsiados nos últimos 30 anos, com diagnóstico de ruptura cardíaca em decorrência de IAM. Nesse período, a porcentagem de IAM com ruptura do miocárdio foi de 0,2%. Os fatores de risco para ruptura do miocárdio pós-IAM incluem idade avançada, arteriosclerose, diabetes mellitus e hipertensão arterial sistêmica.
