BACKGROUND: Cardiovascular complications, such as death, myocardial infarction, or heart failure, are the leading causes of morbidity and mortality in adult patients undergoing major noncardiac surgery.
OBJECTIVE: To evaluate the effects of an accurate preoperative cardiac evaluation, together with optimized perioperative drug therapy, in reducing cardiovascular events in patients undergoing open aortic surgery for abdominal aneurysm.
METHODS: Between January 2000 and December 2008, we considered all consecutive patients undergoing elective abdominal aortic open surgery at the Vascular Surgery Unit of the University of Study-Spedali Civili (Italy). Since January 2003, we have used an intensive cardiac preoperative evaluation: patients with at least one cardiac risk factor received a preoperative cardiac evaluation; all non-invasive and invasive tests were performed preoperatively when indicated by the consultant cardiologist, that also optimized the pharmacological perioperative therapy. The outcome of the 418 patients undergoing surgery between 2003 and 2008 was compared with those of the 204 patients in the previous triennium 2000 to 2002, when only patients with positive history for cardiac disease received a standard preoperative cardiological clinical or instrumental evaluation.
RESULTS: Patients enrolled in the 2003 to 2008 interval were slightly older and with a higher prevalence of comorbidities compared with those observed in the previous triennium; furthermore, the number of noninvasive tests performed before surgery increased significantly. Nevertheless, the number of major cardiac perioperative complications decreased over time: particularly, in-hospital mortality rate was 0.9% in the latter period, compared with 3.4% in the years 2000 to 2002. Also, the long-term mortality was significantly reduced in patients operated on between 2003 and 2008 compared with those operated on in the previous triennium.
CONCLUSION: These data suggest a significant benefit of an intensive cardiac preoperative evaluation in reducing the incidence of perioperative and postoperative cardiac morbidity and mortality.
