Hypertrophic cardiomyopathy is a disease caused by the inability of relaxation of the heart, altering pumping blood into the bloodstream. The cause of this disease is hypertrophy (enlargement) of the walls of the ventricles. In general, patients show dyspnea (breathlessness) in response to heart failure but in many cases may be asymptomatic, and is considered one of the most common causes of sudden death in young people. Among other complications of hypertrophic cardiomyopathy include arrhythmias, angina pectoris or myocardial infarction. Your treatment is based on the use of drugs that enhance arrhythmias and heart contractility although the use of the ICD (defibrillator autoimplantable) in cases where the risk of sudden death is important may also be necessary. In addition, cardiomyopathy is an inherited disease, so it is highly advisable to visit a cardiologist when there is a family history of this disease.
