Coronary artery disease (CAD) is a condition that affects the arteries that supply blood to the heart (called coronary arteries) [2]. It is caused by plaque buildup in the wall of these arteries, which can reduce or block blood flow to the heart muscle [2]. Symptoms of CAD include chest pain, shortness of breath, and fatigue [1], but it can also be asymptomatic until a major event such as a heart attack occurs [3]. Treatment for CAD includes lifestyle changes such as quitting smoking and eating healthy, medications such as statins and ACE inhibitors, and procedures like angioplasty or bypass surgery [4][5][6][7]. Coronary artery disease is the most common type of heart disease and is the leading cause of death in both men and women in the United States [5]. It has been linked to risk factors including high cholesterol levels, diabetes mellitus, hypertension, obesity, physical inactivity, family history of cardiovascular diseases and smoking habits[8][9]

Coronary artery disease (CAD) is a type of cardiovascular disease that occurs when the coronary arteries, which supply oxygen-rich blood to the heart muscle, become narrowed or blocked due to plaque buildup. This can lead to chest pain (angina), shortness of breath, and other symptoms. CAD can also cause a heart attack if an artery becomes completely blocked. Treatment for CAD may include lifestyle changes such as quitting smoking and eating a healthy diet, medications such as aspirin and cholesterol-lowering drugs, or surgery such as angioplasty or bypass surgery.
