[Multivessel PTCA as an alternative to bypass operation: effect of complete revascularization on long-term follow-up].
In this study we examine the influence of the initial grade of revascularisation on clinical follow-up in patients with multivessel PTCA instead of CABG. Between I/85 and VII/89 multivessel PTCA was performed in 231 patients (202 m, 29 w; age 57 +/- 9 years). 71% of the patients had 2-vessel disease (VD), 14% 3-VD. 15% had angioplasty of one major and at least one important side branch. Clinical follow-up was achieved by a questionnaire 19.8 +/- 10.1 months after PTCA. 473 of 508 (93.1%) treated stenoses were successfully (residual stenosis less than 50%). 198 patients (86%) had successful angioplasty of all treated lesions. 31 patients (13%) had failed PTCA of one stenosis, 1 patient of both treated lesions. 1 patient underwent emergency CABG. A complete revascularisation (group A) - no residual stenosis greater than 50% in any coronary artery - was achieved in 164 patients (71%). 65 patients (28%) had incomplete revascularisation [group B]. 206 patients (89.1%) had clinical follow-up by questionnaire, 144 patients in group A (87.8%) and 60 patients in group B (92.3%) [n.s.]. 3 patients had died by noncardiac reasons (two in group A and one in group B), 1 patient of group A by cardiac reason. 70% in group A and 68% in group B had continuous clinical improvement (n.s.). Total amount of cardiac events (PTCA, CABG, cardiac death, MI) showed no significance between both groups - 35 (24%) vs 23 (38%). Patients in group B had more CABG (12% vs 3%) and angioplasty of further lesions (7% vs 1%) [p less than 0.05] during follow-up. We conclude multivessel PTCA shows good primary results with low risk.(ABSTRACT TRUNCATED AT 250 WORDS)
