Andrea Morelli, M.D., of the University of Rome, Italy, and colleagues conducted a study to investigate the effect of the short-acting beta-blocker esmolol on the heart rate of patients with severe septic shock and high risk of death.
Septic shock is associated with adverse effects on cardiac function. Beta-blocker therapy controls heart rate and may improve cardiovascular performance, but concerns remain that this therapy may lead to cardiovascular decompensation (inability of the heart to maintain adequate circulation), according to background information in the article.
