CT coronary angiograms are increasing in popularity as a non-invasive screening test for detecting blocks in coronary arteries. Coronary arteries are blood vessels supplying oxygenated blood to the heart. Veins are blood vessels returning deoxygenated blood to the heart.

CT coronary angiography, in addition to a CT CAC, is arguably the best test for estimating whether someone has evidence of coronary artery disease and what that means for their near-term risk of a heart attack. This article is part 2 of a series on cardiac CT. And that requires a slightly different approach.

. ‘ Snipers Alley ’, it turns out, is an age between 40-60, where mostly males were having fatal heart attacks. These patients were not overly bothered about having a heart attack at age 80, but usually, one of their friends, aged 52 or so, had just had a heart attack, and they did not want to be next.

This is about estimating your near-term risk of a heart attack. The most accurate way (But not the only way) to answer this question is whether or not you have plaque in your coronary arteries. This also means that if you have a CAC score of 0, you have no calcified plaque in your coronary arteries. Not zero risk.

In general, the more calcified or fibrous a plaque is, the less dangerous it is, as it is less likely to rupture and cause a heart attack. Fatty or necrotic plaque is often described as ‘vulnerable’ plaque, with the vulnerability being related to the risk of a heart attack.

Diamond and Forrester accomplished this by first establishing the prevalence of coronary artery disease based on how clinically likely patients with chest pain symptoms were found to have coronary disease based on a coronary angiogram. More cardiac injury means more dead heart muscle, and a larger scar.
