Coronary artery disease (CAD) is a condition where the coronary artery is narrowed by fatty plaque that restricts the flow of blood to the cardiac tissues. When too little blood reaches the cardiac cells, the cells are deprived of oxygen and nutrients. Eventually, the cardiac cells die and leave permanent tissue damage. On the other hand, if blood flow is totally blocked and the cardiac tissues are deprived of oxygen and nutrients, a heart attack ensues.
Patients with coronary artery disease experience chest pain on exertion and during emotional stress but gets better with rest.
Coronary artery disease also contributes to hypertension, which may lead to heart failure.
