What is the effect of beta-blocker therapy on clinical outcomes of acute myocardial infarction after successful primary angioplasty?
A systematic review conducted by Kernis et al. (2004) found that beta-blocker therapy may improve clinical outcomes of acute myocardial infarction after successful primary angioplasty. Further studies conducted by Freemantle et al. (1999) and de Peuter et al. (2009) found that selective and non-selective beta blockers may reduce the risk of vascular events in patients with acute coronary syndrome or heart failure. Additionally, Packer et al. (1996) and Leizorovicz et al. (2002) found that beta blockers may reduce morbidity and mortality in patients with chronic heart failure.
