Coronary Heart Disease


Coronary Heart disease (CHD) is generally caused by narrowing of the blood vessels due to a condition called atherosclerosis which leads to blockages of the arteries restricting blood flow to the heart. This results in angina. If the pain is severe it could be fatal.


According to Medilexicon's medical dictionary: Coronary artery disease is "narrowing of the lumen of one or more of the coronary arteries, usually due to atherosclerosis; myocardial ischemia; can cause congestive heart failure, angina pectoris, or myocardial infarction."


Atherosclerosis is caused due to the buildup of cholesterol and fatty deposits/plaque on the inner walls of the arteries. This fatty deposits/plaque can restrict the free flow of the blood to the heart. Without an adequate blood supply, the heart becomes starved of oxygen and results in a chest pain called angina.
