The aim of the study was to evaluate the efficacy and safety of abciximab (ReoPro) in primary percutaneous transluminal coronary angioplasty (P.T.C.A.) in patients with myocardial infarction (M.I.). From June 96 to October 97, 16 patients with a mean age of 58 +/- 12 years, 86% males, with myocardial infarction (less than 12 hours of pain) were treated with ReoPro during P.T.C.A. The infarction was anterior in seven patients (44%), inferior in eight patients (50%) and non-Q wave in one patient (6%). Nine patients (47%) had a previous history of angina or myocardial infarction. The mean time from onset of symptoms to hospital arrival was 306 +/- 370 min and the mean time between hospital admission and the beginning of the procedure was 79 +/- 86 min. P.T.C.A. was performed on the anterior descending artery and right coronary in 44% and 56%, respectively. The success rate was 94%. Stents were used in 31%. In patients with angiographic success, we obtained TIMI III flow in 14 patients and TIMI II in one patient. No complications arose during P.C.T.A; no significant changes in platelets or hemoglobin were observed after the procedure. In this group of patients, one case of hematoma was found at the site of puncture with no need for transfusion. During hospitalization, no major coronary events were found. During the follow-up of 10.5 +/- 4.9 months, one patient died after non cardiac surgery and one patient was submitted to coronary artery bypass graft; there was no reinfarction nor new P.T.C.A.
Conclusions: In our experience with ReoPro during direct angioplasty, we obtained good immediate and long term results, with no significant bleeding complications.
