Causes
Coronary artery disease (CAD) occurs when fatty substances get stuck to the walls of coronary arteries, which narrows the arteries and constricts blood flow. This causes a lack of oxygen and blood to the heart, which can result in a myocardial infarction (heart attack). CAD leads to constricted arteries, which leads to a lack of blood flowing through the arteries as well as oxygen, a process called atherosclerosis. Atherosclerosis is the most common cause of coronary ischemia.
CAD can be contracted over time. Certain factors play into this, for example, a family history of CAD. Other factors include smoking, high blood pressure, diabetes,obesity, inactive lifestyle and high cholesterol.
