Abstract

Limited contemporary data exist on the cardiovascular risk of patients with prior coronary artery bypass grafting surgery (CABG) requiring diagnostic coronary angiography. We examined the prevalence and control of coronary artery disease risk factors and the outcomes of 367 prior CABG patients who underwent diagnostic coronary angiography between October 1, 2004 and May 31, 2007 at the Dallas Veterans Affairs Medical Center. Mean age was 65 +/- 9 years, 97% were men, and the mean time from CABG to diagnostic angiography was 8.2 +/- 6.1 years. Hypertension, low-density lipoprotein cholesterol, diabetes mellitus, smoking, and obesity were suboptimally controlled in 70%, 59%, 47%, 33%, and 50%, respectively. Intake of statins and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers was 88% and 81%, respectively. After a mean follow-up of 1.4 +/- 0.8 years, the incidence of death and major cardiovascular events was 10% and 32%, respectively. In spite of significant improvement compared to previous studies and good compliance with indicated medications, contemporary prior CABG patients undergoing coronary angiography still have multiple and poorly controlled coronary artery disease risk factors and high risk for cardiovascular events. Novel pharmacologic and behavioral treatment strategies are needed.
