Coronary artery and vascular diseases are leading causes of morbidity and mortality worldwide, affecting the arteries that supply blood to the heart and other vital organs. Conditions such as coronary artery disease (CAD), atherosclerosis, and peripheral vascular disease (PVD) develop when plaque builds up in the arteries, narrowing blood flow and increasing the risk of heart attacks, strokes, and other complications. Early detection through advanced imaging techniques and regular monitoring of risk factors such as high cholesterol, blood pressure, and smoking is essential for effective prevention. Treatment often involves a combination of medications, lifestyle changes, and in some cases, surgical interventions like angioplasty or bypass surgery, which restore proper blood flow and reduce the risk of severe cardiovascular events.
