title: Contribution of stenting to the results of rescue PTCA.
abstract: Failed thrombolysis in acute myocardial infarction (AMI) is associated with increased mortality. Controversial benefit of rescue percutaneous transluminal coronary angioplasty (PTCA) in these setting has been published. The feasibility, safety, and contribution of stenting to the outcome of AMI patients treated with this strategy is unknown. We studied the angiographic result and clinical outcome of 33 patients with failed thrombolysis referred for rescue angioplasty. Twenty-three patients had stenting and 10 patients did not have stenting. Both groups had similar clinical and angiographic characteristics. Stent indications were nonoptimal result, 40%; bailout, 40%; elective, 20%. Angiographic success was 100% with stent vs. 91% with balloon alone (P < 0.8). Postprocedure residual stenosis was 1.5% (0%-10%) with stent vs. 18.05% (0%-30%) with balloon alone (P < 0.01). Thirty-day outcome with and without stent was mortality, 0% vs. 13% (P < 1.0); reinfarction, 10% vs. 0% (P < 0.30); target vessel revascularization, 0% vs. 21% (P < 0.21). The 6-month mortality was 0% with stent vs. 14% (P < 0.5). We conclude that stenting during rescue angioplasty is feasible, safe, and is associated with better immediate angiographic results. Although no obvious clinical benefit was found, a potential decrease in the revascularization rate was suggested.
