Coronary artery disease (CAD), arterial hypertension, chronic bronchitis and diabetes mellitus are the most frequently encountered diseases complicating the clinical course of the vascular patient. Clinical signs of cardiac or pulmonary disease are often absent in patients with decreased functional capacity due to claudication. For instance, clinical evidence of coronary artery disease was found in 36% of patients scheduled for different vascular surgical procedures, whereas coronary angiography revealed significant stenoses in as many as 53-68%. ⋯ It remains to be shown if the use of coronary angioplasty prior to peripheral vascular surgery can provide a more satisfactory overall outcome. Several non-invasive techniques have been suggested to improve the identification of high-risk patients undergoing vascular surgery. These tests include exercise ECG, ambulatory ECG, dipyridamolethallium scintigraphy and determination of left ventricular ejection fraction by gated radionuclide imaging. (ABSTRACT TRUNCATED)
