Hypertensive heart disease

Definition:

Hypertensive heart disease is a late complication of hypertension (high blood pressure) in which the heart is affected.

Causes, incidence, and risk factors:

High blood pressure increases the heart's workload, and over time, this can cause the heart muscle to thicken. As the heart pumps against elevated pressure in the blood vessels, the left ventricle becomes enlarged and the amount of blood pumped by the heart each minute (cardiac output) goes down. Without treatment, symptoms of congestive heart failure may develop.

High blood pressure is the most common risk factor for heart disease and stroke. It can cause ischemic heart disease (decreased blood to the heart muscle that results in anginal chest pain and heart attacks ) from the increased supply of oxygen needed by the thicker heart muscle.

High blood pressure also contributes to thickening of the blood vessel walls, which in turn may aggravate atherosclerosis (increased cholesterol deposits in the blood vessels). This also increases the risk of heart attacks and stroke.

Hypertensive heart disease is the leading cause of illness and death from hypertension. It affects approximately 7 out of 1,000 people.
