Coronary Heart Disease (CHD) (aka: Coronary Artery Disease (CAD); Atherosclerosis; is the leading cause of death worldwide. It is a disease in which a waxy substance called plaque (plak) builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart muscle. Over time, CHD can weaken the heart muscle and lead to heart failure or irregular heart rhythms (arrhythmia). The purpose of the community is to share support and information with Coronary Heart Disease patients, their loved ones, and caregivers.
