ABSTRACT
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.

Although the role of nuclear cardiology is currently well consolidated, the addition of new radiotracers and modern techniques makes it necessary to continuously update the requirements, equipment and clinical applications of these isotopic tests. The characteristics of the radioisotopic drugs and examinations presently used are explained in the first part of this text. In the second, the indications of them in diagnostic and prognostic evaluation of the different coronary diseases are presented.

Although the role of nuclear cardiology is currently well consolidated, the addition of new radiotracers and modern techniques prompt us to permanently update the requirements, equipment and clinical applications of these isotopic tests. Radioisotopic drugs, instrumentation and characteristics of radionuclide tests that are presently used are explained in the first part of this text. In the second part, diagnostic and prognostic indications of these tests are presented in detail.
