CAD is thought to begin with damage or injury to the intimal layer of coronary artery‚ sometimes as early as childhood. The damage may be caused by various factors‚ including: smoking‚ hypertension‚ hypercholestromia‚ diabetes or insulin resistance‚ radiation therapy to the chest‚ as used for certain types of cancer‚ and sedentary lifestyle. Once the intimal layer of coronary artery is damaged‚ fatty deposits (plaques) made up of cholesterol and other cellular waste products tend to accumulate at
