Description
Hypertrophic cardiomyopathy is one of several forms of heart muscle disease which commonly affects cats and is rarely diagnosed in dogs.
The disease is characterised by gross thickening of the muscle in the walls of the heart which makes the walls stiff and less compliant. This results in poor filling of the heart chambers with blood during the diastolic phase of contraction, and inadequate output of blood during systole. The clinical signs of this condition are those of heart failure.
