OBJECTIVE: The determination of high risk @entity1 for @entity944 and sustained @entity1165 after @entity583 constitutes the main goal to decrease morbidity and mortality. Every attempt that decreases the frequency of late potentials (LPs) on signal averaged ECG (SAECG) and @entity1162 (QTc-d) may improve prognosis of @entity1 . In this study, the effect of @entity1406 on frequency of LPs and QTc-d was investigated. METHODS: Thirty-five @entity1 (mean age 53 +/- 9 years) with @entity583 who were not given thrombolytic therapy were enrolled. @entity1 in whom @entity1406 was not administered formed group I (n = 20) and @entity1 who were given @entity1406 constituted group II (n = 15). @entity1406 was administered as an initial dose of 15 mg intravenously, following 6-8 hours 100 mg/d orally. To determine the frequency of LPs, SAECG records were performed on admission and at the end of the first week. At the same time, resting ECG recordings (12 leads, 50 mm/s) were obtained to calculate QTc-d. Variance analysis was used for statistical analysis. RESULTS: In group I; frequency of LPs were found 30% on admission and at the end of the first week. In group II; frequency of LPs were 6% on admission and at the end of the first week there was no LPs. There was no statistically significant difference between two groups according to TQRS, RMS-40, LAS40 and QTc-d CONCLUSION: @entity1406 decreases the frequency of LPs. It has no effect on cQT-d.
