What is the outcome of the RITA-2 trial? 
The Seven-year outcome of the RITA-2 trial showed that coronary angioplasty was more effective than medical therapy for patients with stable angina due to coronary heart disease (Henderson et al., 2003). The study followed 1,873 patients with stable angina and showed that coronary angioplasty was associated with a lower rate of death, myocardial infarction, and stroke when compared to medical therapy. The results suggest that coronary angioplasty is an effective treatment option for patients with stable angina.
