What are the effects of Percutaneous Coronary Interventions (PCI) versus medical therapy on angina relief?
A meta-analysis of research studies conducted by Wijeysundera et al. (2010) found that Percutaneous Coronary Interventions (PCI) were found to be superior to medical therapy alone in providing angina relief in patients with stable coronary artery disease. Specifically, they found that PCI was associated with a significant 5.9 % absolute risk reduction in angina occurrence compared to medical therapy alone. This finding was supported by the research conducted by Ko et al. (2012).
