[Clinical practice guidelines of the Spanish Society of Cardiology for surgical risk assessment in cardial patients treated with non-cardiac surgery].

All patients undergoing a surgical intervention require a cardiovascular evaluation that establishes the surgical risk. On the other hand, an important proportion of the deaths that happened during the surgery are due to cardiovascular complications, many of them could be avoided with a cardiac risk screening. The surgery and the anesthesia subject the patient to stress situations during the perioperative period that forces the check upon capacity of the patient to respond to those demands, dissuading surgery if it considered that the risk is very high. The rate of major surgery in elderly patients is growing, with the increase in cardiovascular complications, mainly myocardial infarction, unstable angina and perioperative heart failure. Following we establish some recommendations for the cardiovascular assessment of the cardiac patient that will undergo noncardiac surgery.
