From the Paper:

"The constricted blood supply to the heart means reduced oxygen supply to the heart muscles. When the blood supply is sufficiently restricted (but not completely blocked), chest pain known as angina pectoris , results; when the arteries are completely blocked due to plaque build-up or due to plaque-rupture resulting in a blood clot (called thrombus), a heart attack (also called myocardial infarction) occurs. After a heart attack, part of the heart muscles die due to lack of oxygen and the episode may prove fatal or the sufferer may survive an attack, depending on the severity of the infarction and/or the medical attention provided. Both these conditions, i.e., sufficient constriction of the coronary arteries resulting in angina or heart attack constitute Coronary Heart Disease."
