Sažetak
The aim of our study was to evaluate the impact of left main coronary artery stenosis, (>60%) on operative risk in coronary artery bypass surgery. Retrospective analysis of 310 consecutive patients with coronary artery disease who underwent same technique CABG between 1/1998 and 3/2000. Patients were divided into two groups. LMS group (with left main coronary artery stenosis, n=52 ; 16.8%, 43 men, mean age 61.6 +/- 5.2) and NLMS group (without left main coronary artery stenosis, n=258 ; 83.2%, 208 men, mean age 60.8 +/- 6.5). Myocardial protection was ensured by intermittent aortic crossclamp technique. No patients were treated with preoperative IABP. In LMS group significantly more patients had postoperative complications as follows: arrhythmia (p<0.007), low cardiac output (p<0.0007), respiratory failure (p<0.002), myocardial infarct 3.8% in LMS group vs. 1.6% in NLMS group (p=NS). The mean number of bypassed vessels was 2.8 in LMS group vs. 2.7 in NLMS group per patient (p=NS). IMA was used in 42.3% in LMS group vs. 38.4% in NLMS group (p=NS). Perfusion time was significantly prolonged in LMS group (p=0.01).Ischaemia time was 24.4 min in LMS group vs. 25.9 min in NLMS group (p=NS).There were no in-hospital deaths in LMS group vs. 1.9% in NLMS group (p=NS). No statisticaly significant mortality difference between two groups (no in-hospital deaths in LMS group vs. 1.9% in NLMS group). Significantly more patients with postoperative complications in LMS group. We belive that intermittent aortic crossclamp technique provide good myocardial protection for patients with significant left main coronary artery stenosis.
