Pcta Versus Medical Treatment for Non-Acute Coronary Heart Disease

A systematic review 1 including 6 RCTs with a total of 1904 subjects was abstracted in DARE. The risk ratio for angina was 0.70 (95% CI 0.50 to 0.98), for death 1.32 (95% CI 0.90 to 2.25), for coronary artery bypass graft 1.59 (95% CI 1.09 to 2.32) and repeated angioplasty 1.29 (95% CI 0.71 to 3.36).

Comment: The level of evidency is downgraded by inconsistency (the results were pooled although there was significant heterogeneity) and by imprecise results (limited study size for endstage events).
