Coronary Artery DiseasesEffectiveness of early coronary angioplasty and abciximab for failed thrombolysis (reteplase or alteplase) during acute myocardial infarction (results from the GUSTO-III trial)☆

Study design
This was a prospectively designed analysis of a subgroup of patients in the Global Use of Strategies To Open occluded coronary arteries (GUSTO-III) trial who underwent early PTCA.8 In brief, patients of any age who had ST-segment elevation ≥1 mm in 2 consecutive limb leads or ≥2 mm in 2 precordial leads, or bundle branch block <6 hours after symptom onset were eligible. Patients were excluded from GUSTO-III for factors related to bleeding or stroke risk. Patients were randomized in a 2:1 ratio
Results
Baseline characteristics and outcomes (death, stroke, reinfarction) of early PTCA patients in the analysis did not differ significantly from those of early PTCA patients who were not analyzed (Table I), except for the incidence of diabetes (15% vs. 22%) and United States enrollment (82% vs. 56%).
Discussion
Our analysis of patients with AMI undergoing early PTCA (within 24 hours of thrombolysis) in the GUSTO-III trial supports the concept that concomitant abciximab may offer substantial benefit to these patients. In most studies, patients undergoing “rescue” PTCA after failed thrombolysis have had higher mortality than patients with successful reperfusion.1, 4 In this study, abciximab given during early PTCA after clinically failed thrombolysis was associated with a trend toward lower 30-day

One-year clinical outcome of patients treated with or without abciximab in rescue coronary angioplasty
2013, International Journal of CardiologyCitation Excerpt :We found a low incidence of major bleedings and vascular complications without significant differences in between the groups treated with or without abciximab. These findings are consistent with some authors [12] but in conflict with others who report a trend [11] or a significant increase [20] in major bleedings in patients treated with abciximab. The lower risk of bleedings and vascular complications observed in our population is in line with recent findings [21] and is probably related to a wide use of radial approach, weight adjusted heparin doses, smaller sheath size.
