Abstract:
Objective To evaluate the clinical outcomes of patients complicated with major bleeding after primary coronary intervention (PCI) for acute ST-segment elevation myocardial infarction (STEMI). Methods During the period of January 2004-January 2008, primary PC1 was performed in 412 consecutive patients with acute STEMI at Shanghai Ruijin Hospital. The clinical data were retrospectively analyzed. Major adverse cardiac events (MACE), including death, reoccurrence of myocardial infarction and target vessel revascularization, in patients with major bleeding were compared with that in patients without major bleeding. Results Compared to patients without bleeding, the patients with bleeding were older (70.0 ± 8.9 years vs 64.9 ± 12.7 years, P = 0.04), mainly the females (51.9% vs 23.1%, P = 0.001) and treated more often with glycoprotein (GP) Ⅱb/Ⅲa receptor inhibitor (88.9% vs 69.4%, P = 0.03) or intra-aortic balloon pump (7.4% vs 1.3%, P = 0.02). In-hospital and one-year MACE rate in the patients with bleeding was 18.5% and 37.0% respectively, which were significantly higher than that in the patients without bleeding (5.7% and 14.3%, with P = 0.008 and P = 0.002, respectively). Multivariate analysis indicated that patient aged over 70 years, feminine gender and use of GP Ⅱb/Ⅲa receptor inhibitor were independent predictors for the occurrence of major bleeding. The occurrence of major bleeding after primary PCI was significantly correlated with MACE occurred within one year after the procedure (OR 2.79, 95% CI: 2.21-5.90, P < 0.001). Conclusion In patients with acute STEMI, the occurrence of major bleeding after primary PCI is closely linked to the increased MACE rate within one year after the treatment. Feminine gender, aged patient and use of GP Ⅱb/Ⅲa receptor inhibitor are independent predictors to increase the danger of major bleeding.
