What Are the Clinical Features of Hypertrophic Obstructive Cardiomyopathy?


What symptoms can hypertrophic obstructive cardiomyopathy cause?


There are some clinical features (symptoms or signs) of hypertrophic obstructive cardiomyopathy.

Pre-syncope or exertional syncope

It is a common symptom indicating dynamic left ventricular outflow tract obstruction ± ventricular dysrhythmia. People with this sign are at risk of sudden cardiac death.

Pulmonary congestion

Due to left ventricular dysfunction, pulmonary congestion may develop, and this can also cause fatigue, orthopnoea, exertional dyspnea, and nocturnal dyspnea.

Chest pain

Chest pain is also called angina. The pain occurs because of increased demand in thicker myocardial walls and reduced supply from aberrant coronary arteries due to damaged heart muscle.


Palpitations is caused by ventricular or supraventricular arrhythmias.
