Aspirin therapy, as opposed to statin use, for non-obstructive coronary artery disease does not reduce major cardiovascular events, according to a new study. Non-obstructive coronary artery disease occurs when there is less than 50% stenosis, or narrowing, of the coronary arteries due to plaque buildup. Coronary CT angiography (CCTA) is often recommended as a first-line test to detect plaque. Medications called statins are commonly prescribed for patients who are diagnosed with non-obstructive coronary artery disease. Statins reduce the production of low-density lipoprotein (LDL) cholesterol and draw cholesterol out of plaque, therefore stabilizing the plaque and reducing the risk of it...
