Abstract/OtherAbstract:
Complete right and left bundle branch block and advanced atrioventricular block present on admission electrocardiograms of patients with acute myocardial infarction, are associated with poor short and long-term outcome. Little is known about the impact of intermediate QRS prolongation (0.09-0.11 s) on the prognosis of acute myocardial infarction. In this study, among 1100 consecutive patients with acute myocardial infarction treated with thrombolysis, the QRS duration on admission electrocardiogram was <0.09 s in 536 (48%) patients, between 0.09 and 0.11 s in 496 (45%) patients and >0.11 s in 78 (7%) patients. QRS duration was strongly associated with 7-day (0.6%, 6%,18%, P<0.001), 30-day (1%, 8%, 22%, P<0.001) and 1-year (3%, 11%, 26%, P<0.001) all-cause mortality. After adjustment for significant variables associated with 1-year mortality, including age, female gender, diabetes mellitus, systemic hypertension, previous myocardial infarction, anterior myocardial infarction and Killip class> or =2 on admission, both levels of QRS prolongation remained significant independent predictors of short and long-term all-cause mortality.
