This review highlights the heterogeneity of hypertrophic cardiomyopathy and emphasizes the importance of recognizing distinct clinical profiles to understand patient prognosis.
Hypertrophic cardiomyopathy (HCM) is a myocardial genetic disease relatively common in the general population with heterogenous clinical presentation, natural history and prognosis. About 60% of HCM patients have a stable clinical course, while others may experience a variety of HCM-related complications which follows relatively independent pathways, and that can be distinguished in different subgroups. These subgroups are represented by patients with left ventricular outflow tract obstruction; patients with end-stage disease and reduced or preserved systolic function; patients with apical hypertrophy; patients with apical aneurysm; patients with atrial fibrillation, patients at high risk of sudden death and patients with preclinical HCM. The purpose of this review was to describe each of these clinical profiles with its prognostic implications.
