Should You Get a Calcium Score Test? Who Needs This Heart Screening
Here's the paradox of cardiovascular disease: it kills more people than almost any other condition, yet it develops silently for years before causing any symptoms. By the time a patient has a heart attack, the disease has often been building for decades. The Coronary Artery Calcium (CAC) score test is one of the few tools that can detect this silent buildup — long before symptoms appear, and early enough to change the outcome. What is a Calcium Score Test? A Coronary Artery Calcium (CAC) scan is a non-invasive, low-radiation CT scan that takes about 10 minutes and requires no contrast dye or special preparation. It measures calcium deposits in the walls of the coronary arteries — the blood vessels supplying the heart muscle. Calcium in arteries is a marker of atherosclerosis: the gradual accumulation of plaque that narrows arteries and increases heart attack risk. The more calcium, the more disease. Results are reported as an Agatston score: Score 0: No detectable calcium; ...
