How is coronary artery disease (CAD) diagnosed?   A disorder known as coronary artery disease (CAD) refers to the thickening of one or more of the arteries that carry blood to the heart. Over time, fats, cholesterol, and other chemicals are accumulated in arteries, where they interact with blood cells to form plaque that narrows the artery lumen. This condition is referred to as atherosclerosis and can result in heart attacks, peripheral vascular disease or a stroke, classified as cardio-vascular disorders (CAD). In CAD, the blood supply to the heart is affected leading to Angina and ultimately Heart attack. The trusted method world over, for a confirmed diagnosis of CAD, is Cardiac Catheterization; it is performed by a cardiologist in a Hospital having a cath-lab facility like Aster RV Hospital How are blocks diagnosed in a cardiac catheterization? Cardiac catheterization also known as Coronary Angiogram (CAG) is a procedure, in which a doctor inserts the catheter into a blood vessel in the arm or groin pre-decided. The catheter is used to check for blockages or other issues in the coronary arteries, which deliver oxygen-rich blood to the heart muscle, after being guided via the blood channels to the heart. Afterwards, a dye is injected into the bloodstream from an intravenous (IV) line connected to the vein. It helps doctors see how well blood flows through different parts of the heart on X-rays taken during the procedure. This is the gold standard diagnostic procedure employed to check the coronaries. Cardiac catheterization plays a pivotal role in the evaluation &, if need be, treating of patients with suspected or known heart disease.
