title: Screening of patients with ischemic heart disease by transesophageal atrial pacing and the selection of surgical therapy: in patients with arteriosclerosis obliterans and aortic aneurysm.
abstract: This study evaluated (1) a screening method for ischemic heart disease (IHD) using transesophageal atrial pacing (TEP), and (2) the appropriate surgical therapy for patients with concomitant IHD which was evaluated on the basis of the coronary score (CS) by Leaman. Thirty-nine patients with arteriosclerosis obliterans of the lower extremities (ASO) and 35 with aortic aneurysm underwent TEP and coronary angiography (CAG). Coexistent IHD was diagnosed in 25 patients (64%) with ASO and in 14 (40%) with aortic aneurysm. Screening for IHD by TEP was 96% sensitive, 71% specific, and 87% accurate in patients with ASO, and 79% sensitive, 90% specific, and 86% accurate in patients with aortic aneurysm. Coronary artery bypass grafting (CABG) and peripheral arterial revascularization (PAR) were performed by one stage surgery in 3 patients with a CS of 16 or more. In 18 patients with a CS of 5.5 or less, only PAR was performed. One stage surgery was performed in 6 patients with aortic aneurysm. Four patients had a CS of 9.5 or more, and 2 patients with coexistent stenosis of the left anterior descending branch (LAD) had CS of 3.5 and 8, respectively. Repair of the aneurysm was undertaken in 5 patients with a CS of 8 or less without LAD disease. In patients with ASO showing a CS of 5.5 or less and in those with aortic aneurysm showing a CS of 8 or less (and without LAD disease), the only surgical procedure performed was either PAR or repair of the aneurysm. There were no complications attributable to IHD observed in these patients during the perioperative period.
