[Clinical and angiographic predictors of initial success of percutaneous transluminal balloon coronary angioplasty in patients with ischemic heart disease].
162 patients were investigated to find out the relationship between pre-PTCA clinical and angiographic characteristics and initial PTCA success. There was no relationship between patients pre-PTCA clinical characteristics and procedural success. PTCA in patients with unstable angina (n = 48) was performed after the clinical stabilization (in average on 19th day of hospitalization) and was not followed by reduction in initial procedural success or increase in intra-procedural or post-procedural complications. When coronary angiographic characteristics were considered, the distal coronary artery lesions and coronary artery stenosis 90-99% were associated with statistically significant reduction in procedural success (p = 0.03 for both factors). Complicated lesion morphology was associated with increased overall complication rate of up to 13.5% (p = 0.006 in comparison with non-complicated stenosis) and was the only predictor of poor PTCA results (prognosis).
