Short- and long-term outcomes of patients with electrocardiographic left ventricular hypertrophy after fibrinolysis for acute myocardial infarction.
There is conflicting evidence with regard to the value of electrocardiographic left ventricular hypertrophy (LVH) in myocardial infarction. Of 5,951 patients in the ASSENT-3 trial, 273 (5%) had LVH on baseline electrocardiograms and had significantly higher mortality rates at 30 days (11% vs 6%, p = 0.001) and 1 year (13% vs 8%, p = 0.007). After adjustment for differences in baseline parameters, LVH remained an independent predictor of 30-day (hazard ratio 2.3, 95% confidence interval 1.4 to 3.9) and 1-year (hazard ratio 1.8, 95% confidence interval 1.1 to 2.8) mortality rates. Thus, electrocardiographic LVH is a prognostic tool in identifying short- and long-term mortality rates in patients who have ST-elevation myocardial infarction and receive fibrinolysis.
