Cardiac event-free survival in refractory angina is better with transmyocardial laser revascularization

Among 192 patients with refractory angina, the survival free of a cardiac event (acute myocardial infarction, unstable angina, or class IV angina) was better with transmyocardial laser revascularization (TMLR) compared to continued medical therapy (66 versus 11 percent, p <0.001); this was primarily due to a lower incidence of unstable angina (2 versus 69 percent).
