Hypertrophic Obstructive Cardiomyopathy: Patient Volume

2020 - 2023

Hypertrophic obstructive cardiomyopathy (HOCM) is the thickening of the lower chambers of the heart. The septal muscle, which divides the right and left chambers, is especially affected by HOCM. The condition can impede blood flow from the heart to the aorta. Cleveland Clinic physicians use a comprehensive approach to diagnose and treat patients with HOCM. This includes a physical exam, electrocardiograph, chest X-ray, echocardiogram, and magnetic resonance imaging.
