Heart Disease
Heart Disease (pronunciation: /hɑːrt diːˈziːz/) refers to a range of conditions that affect the heart. Diseases under the heart disease umbrella include coronary artery disease, heart rhythm problems (arrhythmias), and congenital heart defects, among others.
Etymology
The term "Heart Disease" is derived from the Old English heorte meaning "heart" and the Latin disease which means "lack of ease".
Types of Heart Disease
- Coronary artery disease - This is the most common type of heart disease in many industrialized countries. It occurs when the arteries that supply blood to the heart muscle become hardened and narrowed due to the buildup of plaque on the inner walls or lining of the arteries (atherosclerosis).
- Heart rhythm problems (arrhythmias) - Arrhythmias are problems with the rate or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm.
- Congenital heart defects - These are problems with the heart's structure that are present at birth. Congenital heart defects change the normal flow of blood through the heart.
