Medical Dictionary: Hypertrophic obstructive cardiomyopathy (HOCM)

Hypertrophic obstructive cardiomyopathy (HOCM): Another name for Hypertrophic cardiomyopathy.
Hypertrophic obstructive cardiomyopathy (HOCM) (condition): Heart damage from thickened heart walls.
Hypertrophic obstructive cardiomyopathy (HOCM): The second most common form of heart muscle disease is hypertrophic cardiomyopathy. Physicians sometimes call it by other names: idiopathic hypertrophic subaortic stenosis (IHSS), asymmetrical septal hypertrophy (ASH), or hypertrophic obstructive cardiomyopathy (HOCM).
In hypertrophic cardiomyopathy, the growth and arrangement of muscle fibers
are abnormal, leading to thickened heart walls. The greatest thickening tends to
occur in the left ventricle
(the heart's main pumping chamber), especially in the septum,
the wall that separates the left and right ventricles. The thickening reduces
the size of the pumping chamber and obstructs blood flow. It also prevents the
heart from properly relaxing between beats and so filling with blood.
Eventually, this limits the pumping action.
