Dyspnea and chest pain are common presenting symptoms of HCM, which can be caused by increased LV filling pressures related to diastolic dysfunction or decompensated heart failure, increased myocardial oxygen demand, or impaired microvascular function. For patients with atherosclerotic coronary risk factors, or when chest pain is not relieved with medication, epicardial coronary artery disease should be considered. Many patients with HCM may be asymptomatic and diagnosed incidentally or through family screening.

Sudden cardiac death is the most devastating presenting manifestation of HCM, with its highest incidence in preadolescent and adolescent children, particularly upon extreme exertion.
