Case description

The video presents the hypertrophic cardiomyopathy (HCM) which occurs if heart muscle cells enlarge and cause the walls of the ventricles (usually the left ventricle) to thicken. Despite this thickening, the ventricle size often remains normal. HCM is frequently asymptomatic until sudden cardiac death. It is usually inherited; caused by a mutation in some of the genes in heart muscle proteins (β myosin). HCM also can develop over time because of high blood pressure or aging. Other diseases, such as diabetes or thyroid disease, also can cause HCM. Many patients are asymptomatic or mildly symptomatic. Main common symptoms are: shortness of breath or chest pain, especially during exercise, fainting and sensation of rapid or pounding heartbeats (palpitations). The most common tests for cardiomyopathy are an ECG, an echocardiogram which show the pumping action of the heart.
