Coronary artery disease (CAD) is a global health issue that quietly affects millions. Often without symptoms until severe complications arise, CAD restricts blood flow to the heart, leading to heart attacks and other potentially life-threatening events. Understanding its risk factors, detection methods, and treatment options is essential in combating this “silent killer.” The Basics of Coronary Artery Disease CAD is caused by the build-up of plaque in the coronary arteries, which supply blood and oxygen to the heart. This plaque, composed of fat, cholesterol, calcium, and other substances, hardens, and narrows the arteries over time. Reduced blood flow deprives the heart of oxygen, causing symptoms such as chest pain (angina) and, in severe cases, heart attacks. This gradual development makes CAD challenging to detect early, underscoring the importance of regular health screenings for at-risk individuals.
