Hypertrophic cardiomyopathy, HCM can be symptomatic or asymptomatic. In a limited number of cases it can lead to sudden cardiac death, SCD. Screening is sometimes used with the aim of reducing SCD.
Description
HCM is a genetic disorder that causes the muscle of the heart (the myocardium) to thicken (or hypertrophy). It can cause dangerous arrhythmias (abnormal heart rhythms). The thickening of the heart also makes it harder for blood to leave, forcing the heart to work more vigorously to pump blood.
HCM occurs in approximately 2 per 1,000 people in the general population, being a primary and familial malformation. The condition is seen in people of all ages. Some studies indicate that HCM is a cause of sudden cardiac death in athletes. The disease is equally prevalent in males and females.
Screening and diagnosis
Screening to detect HCM is an important process in preventing a possible sudden cardiac death.
