Randomized Controlled Trial Comparative Study Clinical Trial
Cost and cost-effectiveness of an early invasive vs conservative strategy for the treatment of unstable angina and non-ST-segment elevation myocardial infarction.
In the Treat Angina with Aggrastat and Determine Cost of Therapy with an Invasive or Conservative Strategy (TACTICS)-Thrombolysis in Myocardial Infarction (TIMI) 18 trial, patients with either unstable angina or non-ST-segment elevation myocardial infarction (UA/NSTEMI) treated with the platelet glycoprotein (Gp IIb/IIIa) inhibitor tirofiban had a significantly reduced rate of major cardiac events at 6 months with an early invasive vs a conservative strategy. ⋯ In patients with UA/NSTEMI treated with the Gp IIb/IIIa inhibitor tirofiban, the clinical benefit of an early invasive strategy was achieved with a small increase in cost, yielding favorable projected estimates of cost per year of life gained. These results support the broader use of an early invasive strategy in these patients.
