Coronary heart disease

Coronary heart disease (CHD) is a type of heart disease, is the end result of the accumulation of atheromatous plaques within the walls of the arteries that supply the myocardium. While the symptoms and signs of heart disease are noted in the advanced state of disease, most individuals with coronary heart disease show no evidence of disease for decades as the disease progresses before the first onset of symptoms, often a "sudden" heart attack, finally arise. After decades of progression, some of these atheromatous plaques may rupture and start limiting blood flow to the heart muscle. The disease is the most common cause of sudden death.
