Heart disease is any number of conditions (or even a combination) that affect the functioning or structure of the heart, and may result in a heart attack or stroke. Examples/types of heart disease include:
Also known as "atherosclerosis", this is when there is a problem with the blood vessels that take oxygenated blood from your heart to the rest of your body. The problem could be narrowing, hardening, or even a blockage. Most heart attacks and angina (chest pain) are caused by coronary arterydisease.
These are disorders that affect heart rhythm, making the heart beat too quickly, too slowly, or in a disorganized way — disrupting proper blood flow.
Structural Heart Disease
These are abnormalities or defects in the structure of the heart — muscles, walls, valves, or blood vessels — that can be congenital (from birth) or caused by infection or aging.
