PREDICTORS OF CORONARY-ARTERY RESTENOSIS IN PATIENTS WITH CORONARY HEART-DISEASE (CHD) 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 mont hs after successful PTCA. The overall restenosis rate was 42.6%. Four clinical and angiographic factors were associated with high risk of re stenosis. Residual stenosis greater than or equal to 25% was the stron gest predictor of restenosis (p = 0.002). Among other factors presence of unstable angina, complicated lesion morphology and absence of inti mal dissection had equal value of significance (p = 0.02 in all the ca ses).
