Many studies suggest that coronary heart disease begins when certain factors damage the inner layers of the coronary arteries.

Causes of Coronary artery disease

These factors include:

• Smoking
• High cholesterol
• High blood pressure
• Diabetes

The buildup of plaque in the coronary arteries may begin at childhood. Over time, plaque can narrow or completely block the coronary arteries and reduces the oxygen rich blood supply to the heart muscle.

The plaque may became harden and develop cracks, platelet a blood cells join together causes blood clots over the cracked plaque. This further narrows the arteries and worsens chest pain called angina or even causes a heart attack.
