Hypertrophic cardiomyopathy
Hypertrophic cardiomyopathy is the thickening of the muscles
that make up the heart. The thickening may interfere with the
normal functioning of the heart by:
- Narrowing the outflow of the ventricle
- Reducing the ability of the heart to relax and fill with blood
during the relaxation phase
- Impairing the ability of the valves of the heart to function
properly
Any situation that increases the rate or force of contraction of
the heart muscle can worsen these symptoms.
