Assessment of Clinical and Angiographic Predictors of Restenosis after PTCA

The aim of the present study was to investigate clinical and angiographic predictors of restenosis after percutaneous transluminal coronary angioplasty (PTCA). The material of the study consisted of 79 patients (64 male) having a mean age 57±7. These patients had multilesion-multivessel PTCA between 1984-1989 and have been rechecked angiographically. Groups developing restenosis or not were compared in regard to different clinical and angiographic criteria. Clinical criteria (age, sex, diabetes mellitus, hypertension, gout, cigarette smoking, hyperlipidemia, familial history, angina pectoris functional class and post-PTCA drug therapy) did not show any significant difference between the two groups. A higher degree of residual stenosis (P<0.01), left anterior descending localization (P<0.005) and left ventricular functional disturbances (P<0.005) were significantly different parameters in the group with restenosis. It is therefore suggested that, in the presence of these angiographic features, frequent angiographic controls after PTCA will be necessary.
