The purpose of the study was to assess the implementation of secondary prevention guidelines of coronary artery disease (CAD) in patients undergoing peripheral revascularization surgery. The design was a descriptive study of the prevalence of cardiac risk factors and preventive pharmacological therapy in vascular surgical patients set in an academic medical center between July 1996 and February 1999. A total of 237 patients were recruited, 82 (35%) having carotid surgery and 155 (65%) having lower extremity bypass. Data were collected from an existing database of a study examining perioperative cardiac events in vascular surgery patients. The majority of patients were hypertensive and 58% of patients had a blood pressure >140/90 mmHg. Most patients (81%) reported a history of tobacco use and 23% were active smokers. Of the 41% of patients who were diabetic, 46% had a random glucose >140 mg/dl. Half of the patients took aspirin, 35% a lipid-lowering medication, 30% a beta-blocker. Patients with lower extremity disease were less likely than patients with carotid disease to be on aspirin (45% vs. 62%), a lipid-lowering agent (30% vs. 45%), or a beta-blocker (26% vs. 39%) (all p<0.05). Of patients with heart disease, more men than women were on aspirin (62% vs. 45%) (p<0.05). In conclusion, our findings suggest that patients presenting for vascular surgery have a high prevalence of modifiable CAD risk factors that are not being adequately managed. Preoperative examination of vascular patients is an important opportunity to assess and implement neglected secondary prevention measures.
