摘要
The long-term beneficial effects of placebo therapy were evaluated in angiogenesis and laser myocardial revascularization trials in patients who had end-stage coronary heart disease. Improvements in mean angina class, exercise treadmill time, and quality of life were mostly maintained at 30 +/- 6 months of follow-up. Persistence of effect cannot be used as evidence or efficacy, and double-blinded trials are essential in this patient population. (c) 2005 by Excerpta Medica Inc.
