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).
对162例患者进行了研究，以确定经皮冠状动脉腔内血管成形术（PTCA）术前的临床和血管造影特征与PTCA初始成功率之间的关系。患者PTCA术前的临床特征与手术成功率之间没有关系。不稳定型心绞痛患者（n = 48）的PTCA在临床稳定后（平均住院第19天）进行，术后初始手术成功率没有降低，术中或术后并发症也没有增加。当考虑冠状动脉造影特征时，冠状动脉远端病变和冠状动脉狭窄90%-99%与手术成功率的统计学显著降低相关（两个因素的p值均为0.03）。复杂的病变形态与高达13.5%的总体并发症发生率增加相关（与非复杂狭窄相比，p = 0.006），并且是PTCA结果（预后）不佳的唯一预测因素。
