Coronary artery disease (CAD) is the most common type of heart disease and occurs when the coronary arteries become narrowed or blocked by plaque buildup. This restricts blood flow to the heart, leading to chest pain (angina), shortness of breath, or even heart attacks. CAD develops over time and is often caused by high cholesterol, high blood pressure, smoking, and unhealthy diet.
Managing CAD involves lifestyle changes, medications, and sometimes medical procedures like angioplasty or bypass surgery to restore blood flow to the heart.
CAD occurs when the coronary arteries, which supply blood to the heart, become narrowed or blocked due to plaque buildup.
Risk factors include high cholesterol, high blood pressure, smoking, obesity, physical inactivity, and a family history of heart disease.
CAD is diagnosed through tests such as ECGs, stress tests, echocardiograms, coronary angiography, and blood tests for cholesterol and inflammation markers.
Treatments include lifestyle changes, medications (such as statins or beta-blockers), and surgical procedures like angioplasty or bypass surgery.
Yes, adopting a heart-healthy diet, regular exercise, quitting smoking, and managing cholesterol and blood pressure can significantly improve outcomes.
