OBJECTIVE: To document the frequency of @entity8526 and their influence on prognosis in a large series of @entity1 with @entity583 who underwent coronary care during a period when thrombolytic therapy was in common usage. BACKGROUND: @entity8526 have been associated with an adverse prognosis following @entity583 , but there are few data on the incidence and outcome of @entity8526 since the introduction of thrombolytic therapy. @entity1 AND METHODS: The study group comprised 1225 consecutive @entity1 with @entity583 treated in the coronary care unit from 1 January 1988 to 31 December 1994. @entity8526 were recorded prospectively and were classified as follows: complete @entity713 associated with @entity543 ; left or @entity714 ; @entity616 ; complete @entity616 involving both bundle branches. RESULTS: Electrocardiographic data were available in 1220 @entity1 . Complete @entity713 occurred in 65 (5.3%), left and @entity714 in 29 (2.4%) and 44 (3.6%) @entity616 in 36 (2.9%) and complete @entity616 involving both bundle branches in 20 (1.6%). The more advanced degrees of block in the bundle branches occurred more commonly in @entity1 with @entity6 , previous @entity1188 . Q-wave @entity1188 , anterior @entity1188 and @entity1002 . Survival analysis showed an increased short- and long-term cardiac mortality in @entity1 with @entity8526 , prognosis worsening as the severity of the conduction defect increased. CONCLUSION: @entity8526 complicated @entity583 in 16% of cases and had a graded impact on the short- and long-term prognosis, @entity1 with advanced bundle branch involvement faring worst. The data showed a small decline in the rate of severe @entity8526 compared with previous studies, possibly reflecting the beneficial effects of thrombolytic therapy on @entity1188 size.

Frequency and prognostic implications of XXXX in @entity583 since the introduction of thrombolytic therapy.
