Abstract

It is not easy to define a plan for the preoperative assessment of the coronary circulation: some studies carried out in the context of vascular surgery are contradictory and no method has a sensitivity and specificity of 100%. Nevertheless, it is essential to select patients with a high risk of perioperative cardiac complications so that their medical treatment can be reinforced or anatomical correction envisaged. A first assessment is obtained from the history, the clinical examination and simple investigations (resting ECG, chest X-ray). Surgical operations which do not impose a major strain on the cardiovascular system do not require further investigations. The risk of postoperative cardiac complications is low in the absence of the nine risk factors defined by Goldman and/or an ischemic syndrome (residual angina after mild physical activity, unstable angina, myocardial infarct). The problem arises in patients with the Goldman risk factors and/or a history of coronary insufficiency and/or coronary insufficiency risk factors (diabetes, tobacco, hypercholesterolemia, age > 70 years, arterial hypertension), who require an operation likely to cause a particularly serious strain on the cardiovascular system. An exercise ECG, by ...Continue Reading
