Coronary Artery Disease: Meaning, Diagnosis and Overview

What is Coronary Artery Disease?

Coronary artery disease also called as coronary heart disease is the most common type of heart disease which affects many individuals throughout the country. This occurs due to the build-up of plaque (cholesterol deposits) in the coronary arteries (blood vessels which supply oxygen and blood to heart). The arteries, which will be smooth and elastic, become narrow and rigid, restricting blood flow to the heart and thus the heart cannot pump properly as it becomes devoid of oxygen and the vital nutrients. Coronary heart disease commonly causes angina pectoris (chest pain), shortness of breath, heart attack (myocardial infarction) and other symptoms.

Control of Diabetes, hypertension, Cessation of smoking, regular exercise and lipid lowering drugs are the mainstay in the treatment of CAD. 

Q4.  How long does it take to cure?
Adequate measure to control the risk factors arrests the progression of the disease into complete block the coronary vessels. Regular exercise and proper medication gradually resolves the cholesterol deposition and make the vessel more patent.
