Left ventricular heart disease, or left ventricular hypertrophy, is caused by high blood pressure, aortic valve stenosis, hypertrophic cardiomyopathy and athletic training, according to Mayo Clinic. It occurs when something causes the heart to work harder than normal to pump blood throughout the body.
High blood pressure, or hypertension, is the most common cause of left ventricular hypertrophy, notes Mayo Clinic. Over one-third of people who are diagnosed with hypertension display characteristics of left ventricular hypertrophy. Aortic valve stenosis is the narrowing of the aortic valve that separates the left ventricle from the aorta. It causes the left ventricle to work harder to pump blood into the aorta due to the narrowing. Hypertrophic cardiomyopathy is a genetic disorder that makes it harder for the heart to pump blood through the body due to an abnormal thickness of the heart muscle. Athletic training or exercise can cause the heart to work harder due to intense and prolonged endurance and strength training.
Although some patients do not show symptoms of left ventricular heart disease, the more common symptoms that patients display are shortness of breath, chest pain, dizziness, fainting, and rapid or pounding heartbeat, explains Cleveland Clinic. Treatment depends on the cause of the condition and includes controlling blood pressure with lifestyle changes or medication, medical management and surgery.
