One of the major limitations in coronary intervention is restenosis. This study was aimed to identify clinical, angiographic, and procedural factors that may be related to the second restenosis (SR). We studied 101 patients who underwent more than two follow‐up coronary angiograms after two coronary interventions between January 1996 and December 1998 in Chonnam University Hospital (out of 4,092 total coronary interventions in 3,030 patients during the same period). The patients were divided into two groups according to the evidence of SR. Fifty‐two patients (group A: 57 ± 10 years, M:F = 44:8) who had SR and the other 49 patients (group B: 54 ± 9 years, M:F = 44:5) without SR were analyzed. Clinical features, angiographic characteristics, coronary interventional procedures, and other risk factors were compared between two groups by univariate analysis and multivariate stepwise logistic regression analysis was performed for the predictive factors for SR. The clinical variables of age, sex, clinical diagnosis, and risk factors were not different between two groups. The lesion severer than B 2 by AHA/ACC classification were associated with SR ( P < 0.05). Recurrent angina as an indication for follow‐up angiography was associated with SR ( P < 0.01). Predictive factors associated with SR were patient's subjective symptom and lesion severer than type B 2 according to AHA/ACC classification. Cathet. Cardiovasc.
