OBJECTIVE: The prognostic significance of recanalisation of a chronically occluded @entity1188 @entity34715 remains controversial, in contrast to early re-opening of the @entity1188 vessel in the acute state of @entity1188 . It was the purpose of this prospective study to discover whether successful recanalisation in the former influences the incidence of @entity299 ( @entity204 , @entity1188 , by-pass operation) and clinical symptoms in the long term. @entity1 AND METHOD: Recanalisation procedures were successful in 58, unsuccessful in 41 of 99 @entity1 (81 @entity1 , 18 @entity1 ; mean age 55 [28-79] years) with anterior wall (n = 53) or posterior wall (n = 46) @entity583 (AMI and PMI, respectively). The two groups were similar with respect to age, sex, left-ventricular function, indication, exercise capacity and premedication. But the interval between @entity1188 and recanalisation was shorter in the @entity1 who had successful recanalisation (5.1 +/- 5.3 vs 7.8 +/- 7.6 months; P < 0.05). Mean follow-up period for all @entity1 was 55.8 +/- 8.9 months after the recanalisation procedure. RESULTS: There were significantly fewer @entity299 after successful than failed recanalisation, both for the total group of @entity1 (5% vs 23%; P < 0.01) and those with @entity3660 (9 vs 36%; P = 0.012). In the @entity1 with PMI there was only a trend in favour of those with successful recanalisation (0% vs 14%; P = 0.058). Symptomatic improvement was reported by 73% of @entity1 after successful but only 40% after failed recanalisation (P < 0.01). CONCLUSION: The results provide pointers towards prognostic indications of recanalisation even after chronic occlusion of the @entity1188 vessel. The procedure should therefore be attempted if the occlusion is morphologically suitable.
