Cardiac risk stratification prior to vascular surgery.

Abstract

A cardiac etiology is the cause of death in approximately 40% to 60% of patients who die in the early postoperative period following vascular surgery. A variety of modalities has been proposed to identify the patient at risk before the surgical procedure. This article puts these modalities in perspective and discusses the increased risk of cardiac complication for the vascular surgery patient, identifies the patient at risk, and defines methods to decrease patient risk.
