Abstract
Background
Thrombolysis is still used when primary angioplasty is delayed for a long time, but 25%–30% of patients require rescue angioplasty (RA). There are no established recommendations for antithrombotic management in RA. This registry analyzes regimens for antithrombotic management.
Methods
A retrospective, multicenter, observational registry of consecutive patients treated with RA at 8 hospitals. All variables were collected and follow-up took place at 6 months.
Results
The study included 417 patients. Antithrombotic therapy in RA was: no additional drugs 22.3%, unfractionated heparin (UFH) 36.6%, abciximab 15.5%, abciximab plus UFH 10.5%, bivalirudin 5.7%, enoxaparin 4.3%, and others 4.7%. Outcomes at 6 months were: mortality 9.1%, infarction 3.3%, definite or probable stent thrombosis 4.3%, revascularization 1.9%, and stroke 0.5%. Mortality was related to cardiogenic shock, age > 75 years, and anterior location. The stent thrombosis rate was highest with bivalirudin (12.5% at 6 months). The incidence of bleeding at admission was high (14.8%), but most cases were not severe (82% BARC ≤2). Variables independently associated with bleeding were: femoral access (OR 3.30; 95% CI 1.3–8.3: p = 0.004) and post-RA abciximab infusion (OR 2.26; 95% CI 1.02–5: p = 0.04).
Conclusions
Antithrombotic treatment regimens in RA vary greatly, predominant strategies consisting of no additional drugs or UFH 70 U/kg. No regimen proved predictive of mortality, but bivalirudin was related to more stent thrombosis. There was a high incidence of bleeding, associated with post-RA abciximab infusion and femoral access.
