More than 33 million US residents (about 10% of the US population) undergo surgery annually. This number is projected to increase substantially by 2020. Internists commonly evaluate the fitness of patients for surgery and help manage their comorbidities in the perioperative period. This chapter has five goals: use the American College of Cardiology and American Heart Association (ACC/AHA) guidelines to estimate cardiac risk, choose the appropriate noninvasive test to further stratify cardiac risk, and recommend risk reduction strategies; understand perioperative management of antiplatelet agents in patients with coronary stents; identify the perioperative risk of pulmonary complications and recommend risk reduction strategies; use appropriate deep vein thrombosis prophylaxis in the surgical patient according to risk; and recommend appropriate preoperative testing.
