OBJECTIVE: To assess the frequency of early remodelling of coronary @entity850 morphology after thrombolytic treatment in @entity1 with @entity583 . DESIGN: Coronary angiograms were analysed by a computerised edge detection analysis system. @entity3979 severity was measured and morphology classified as smooth or complex. @entity1 : Coronary arteriograms were obtained approximately 90 min and 24 h after thrombolytic treatment from 40 @entity1 with @entity583 . MAIN RESULTS: Stenosis morphology was complex in 22 @entity1 (65%) and smooth in 11 (32%) 90 min after thrombolysis. The morphology of 11 (50%) complex coronary stenoses and three (27%) smooth stenoses had changed at 24 h (P < 0.05). The transition from complex to smooth was associated with a reduction in @entity850 severity from 65 (4)% to 51 (5)% (P < 0.05). The @entity850 severity was 63 (4)% and 60 (5)% in those with persistently complex morphology, and 56 (7)% and 50 (5)% in those with persistently smooth morphology at 90 min and 24 h respectively (NS). CONCLUSIONS: Transition of morphology from complex to smooth within 24 h is common. This transition is associated with a reduction in @entity850 severity of a degree greater than that found in persistently smooth stenoses over the same interval. 50% of stenoses are smooth at 24 h.
