What were the results of the Randomized Intervention Treatment of Angina (RITA) trial?
The Randomized Intervention Treatment of Angina (RITA) trial showed that percutaneous coronary angioplasty was more cost-effective than coronary artery bypass surgery and had similar mortality rates. The trial also showed that angioplasty was associated with a higher rate of restenosis and subsequent revascularization. Additionally, angioplasty was associated with better preservation of left ventricular function.
