摘      要:Guidelines from the American Heart Association and the American College of Cardiology, as well as numerous review articles, have strongly and enthusiastically recommended that platelet glycoprotein IIb/IIIa inhibitors be used in patients with medically managed unstable angina or non-ST-segment myocardial infarction (UA/NSTEMI). We explore whether there is sufficient experimental evidence to justify these recommendations. We review the 4 large randomized trials of US Food and Drug Administration-approved platelet glycoprotein IIb/IIIa inhibitors that included medically managed UA/NSTEMI patients, first taking each trial s results at face value and then in the context of likely biases. The risk differences, unadjusted for potential biases, are 2.5% (0.6%, 4.4%) for the Platelet Receptor Inhibition in Ischemic Syndrome Management (PRISM) study, 2.3% (-1.9%, 6.5%) for the Platelet Receptor Inhibition in Ischemic Syndrome Management in Patients Limited by Unstable Signs and Symptoms (PRISM-PLUS) study (tirofiban plus heparin), 0.9% (-0.9%, 2.8%) for the Platelet Glycoprotein IIb/IIIa in Unstable Angina Receptor Suppression Using Integrilin Therapy (PURSUIT) trial, -0.2% (-1.7%, 1.3%) for the least harmful treatment arm of the Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Coronary Arteries (GUSTO-IV) trial, and -1.9% (-6.8%, 3.0%) for the PRISM-PLUS study (tirofiban alone) (positive numbers indicate benefit). The 95% confidence interval produced by combining the studies using a random effects model is -1.3% to 3.2% (mean 0.9%);this is consistent with drugs providing a small benefit, no benefit, or causing harm. Confounding caused by the nonrandom selection of patients for percutaneous transluminal coronary angioplasty and coronary artery bypass grafting in all trials except GUSTO-IV and problems arising from the fact that enrolled patients were much sicker than typical UA/NSTEMI patients are likely to have biased the studies away from t
