What is the effect of beta-blockade on mortality among high-risk and low-risk patients after myocardial infarction?
Gottlieb et al. (1998) conducted a study to investigate the effect of beta-blockade on mortality among high-risk and low-risk patients after myocardial infarction. The results showed that beta-blocker therapy was associated with a significant reduction in mortality among both high-risk and low-risk patients after myocardial infarction. Furthermore, the authors reported that the beneficial effect of beta-blockers was independent of the patient's risk status.
