Factors that were previously reported as associated factors of the severity of CAD (age, gender, cardiovascular risk factors, clinical type of AMI and prior use of ACE inhibitors, angiotensin II receptor blockers, mineralocorticoid receptor antagonists, beta-blockers, antiplatelets, and statins) were not statistically different between ACE I/D genotypes. The gene discussed is ACE; the disease is coronary artery disorder.
