Preoperative Assessment and Optimization of Cardiopulmonary Disease in Noncardiac Surgery

Abstract

AbstractMore than 50 million surgical procedures are carried out every year in the United States with the estimated risk of major adverse cardiac events perioperatively between 1.4 and 3.9%. Given that the majority of surgeries are elective, this allows ample opportunity to identify patients at higher risk of perioperative adverse events and optimize them for surgery. Preexisting cardiopulmonary disease is a major risk factor for adverse events perioperatively and can lead to significant morbidity and mortality. It can predispose patients to perioperative myocardial ischemia and infarction, perioperative pulmonary complications, and perioperative stroke among other complications. This article details an approach to preoperative interview and examination, indications for preoperative testing, and strategies for optimization in patients with underlying cardiopulmonary disease. It also includes guidelines on optimal timing of elective surgery in certain clinical scenarios that can escalate perioperative risk. Through the use of thorough preoperative assessment, targeted preoperative testing, and multidisciplinary optimization of preexisting disease, perioperative risk can be decreased significantly and perioperative outcomes improved.
