[Immediate results of endovascular treatment of coronary arteries in patients with ischemic heart disease].
OBJECTIVE
To assess immediate results of percutaneous coronary interventions (PCI) and finding the predictors of the successful outcomes in various subgroups of patients with coronary artery disease (CAD).


METHODS
Patients (n=1066, (average age 55.7+/-9.2 years, women 12%) treated with coronary artery stenting between 1999 and 2004. According to coronary angiography, 383 (36%) patients had 1-vessel, 502 (47%) - 2-vessel, and 181 (17%) - 3-vessel CAD. The endovascular treatment was made on 1694 coronary stenoses (in average 1.6 stenosis/patient), 356 stenoses (21%) was defined as type A, 745 (44%) - type capital B, and 593 (35%) - type C. PCI was performed with use of inhibitors of glycoprotein receptors IIb/IIIa in 107 (18%) patients.


RESULTS
The complete or partial immediate procedural success of PCI (elimination of at least one coronary stenosis) was achieved in 1002 (94%) patients. The immediate success was achieved in 1575 stenoses (93%). Total rate of major adverse cardiac events (MACE) was 1.3%. There were no deaths, 11 patients (1%) had acute myocardial infarctions, 3 (0.28%) patients had an emergent coronary artery bypass grafting. The immediate procedural success was significantly lower in patients with chronic coronary occlusions (76%) than in patients without coronary occlusions (97%, p<0.0001), as well in patients with stenoses type C as compared with stenoses type A, and B (success rate 77%, 98% and 100%, accordingly, p<0.0001).


CONCLUSIONS
By multifactorial analysis, independent predictors of procedural failure were stenosis type C (small p<0.0001) and chronic occlusion of coronary artery (p=0,03).
