Coronary artery disease is primarily characterized by:

Coronary artery disease mainly results from atherosclerotic plaque buildup inside the coronary arteries, narrowing the lumen and blocking blood flow to the heart muscle. This plaque accumulation reduces perfusion and can lead to myocardial ischemia or infarction when oxygen delivery is insufficient. Inflammation of the pericardium affects the sac around the heart (pericarditis) rather than the coronary vessels. Increased heart muscle mass describes hypertrophy or cardiomegaly, which isn’t the primary lesion of CAD. Genetic defects in red blood cells relate to blood disorders like hemoglobinopathies, not atherosclerotic blockage of the coronary circulation.
