What is the effect of percutaneous coronary intervention (PCI) on quality of life in patients with stable coronary disease?
A meta-analysis of available studies found that PCI in patients with stable coronary disease results in improved quality of life compared to medical therapy alone. A study by Weintraub et al. found improvements in quality of life scores for PCI patients at three and six months after the procedure compared to those who received medical therapy alone. Similarly, the Randomized Intervention Treatment of Angina (RITA) trial found that PCI patients experienced greater improvements in quality of life at three years follow-up than those who received medical therapy only. In addition, the Medicine, Angioplasty, or Surgery Study (MASS II) found that PCI patients had improved quality of life at 10-year follow-up compared to those who received medical or surgical therapy. Taken together, these findings suggest that PCI is associated with improved quality of life in patients with stable coronary disease.
