[Predictors of coronary artery restenosis in IHD patients after transluminal balloon coronary angioplasty].

To determine clinical and angiographic predictors of restenosis after successful PTCA, we analysed the data on 63 patients (68 stenoses) who had undergone repeat coronary angiography during the first eight months after successful PTCA. The overall restenosis rate was 42.6%. Four clinical and angiographic factors were associated with high risk of restenosis. Residual stenosis > or = 25% was the strongest predictor of restenosis (p = 0.002). Among other factors presence of unstable angina, complicated lesion morphology and absence of intimal dissection had equal value of significance (p = 0.02 in all the cases).
