title: [Prevalence of vascular disease in candidates for myocardial revascularization with aortocoronary bypass: review of the literature and practical implications].
abstract: BACKGROUND
  Cardiovascular disease remains the main cause of death and morbidity in the industrialized world. Atherosclerosis is a slowly progressive disease; coronary artery disease may be the first presentation of a systemic pathology. The association between coronary artery disease and peripheral vascular disease has often been confirmed by multicenter trials; nevertheless it still remains a subject of debate.
  
  
  METHODS
  In order to assess the incidence of coronary artery disease and the degree of associated vascular lesions, between January 1997 and September 1999, in the Department of Cardiothoracic Surgery of the Second University of Naples (Italy), all candidates to coronary artery bypass grafting (CABG) were submitted to routine preoperative echo color Doppler study of the carotid vessels, abdominal aorta and iliac-femoral arteries. The correlation between the echo color Doppler findings, the angiographic patterns of coronary lesions and atherosclerotic risk factors was analyzed in all cases.
  
  
  RESULTS
  Among 540 patients undergoing CABG, 418 (77.4%) had carotid disease, with a stenosis > 70% in 62 (11.3%). Forty-nine (79%) patients had asymptomatic severe carotid disease. A significant correlation between the severity of coronary disease and the incidence of severe carotid disease was found (p = 0.02). An abdominal aortic dilation was found in 37 cases (6.7%). Its diameter exceeded 35 mm in 14 patients (2.5%) and in 8 it was associated with triple vessel coronary disease. Atherosclerotic lesions of the iliac-femoro-popliteal axis were found in 394 (72.9%) patients and strongly correlated with the severity of coronary artery disease (p = 0.02); lesions were hemodynamically significant in 91 (16.8%) cases.
  
  
  CONCLUSIONS
  Our study emphasizes the association between coronary artery disease and vascular disease. Non-invasive complete arterial investigation should be routinely performed in patients undergoing CABG.
