Risk factors for major bleeding and for minor bleeding after percutaneous coronary intervention in 634 consecutive patients with acute coronary syndromes.
Of 634 consecutive patients who had percutaneous coronary intervention (PCI) for acute coronary syndromes, 34 (5%) had major bleeding after PCI, 253 (40%) had minor bleeding after PCI, and 347 (55%) had no bleeding after PCI. Significant independent risk factors for major bleeding after PCI were increased troponin I level (P = 0.004; odds ratio [OR] = 4.7), prior coronary artery disease (P = 0.029; OR = 3.7), platelet glycoprotein IIb/IIIa inhibitors (P = 0.002; OR = 9.8), glomerular filtration rate (GFR) <30 versus >or=60 mL/min/1.73 m(2) (P < 0.0001; OR = 39.7), GFR 30-59 versus >or=60 mL/min/1.73 m(2) (P = 0.0001; OR = 9.4), and clopidogrel loading dose >300 mg (P = 0.0001; OR = 8.9). Significant independent risk factors for minor bleeding after PCI were increased troponin I level (P = 0.0004; OR = 2.1), platelet glycoprotein IIb/IIIa inhibitors (P = 0.039; OR = 2.4), GFR 30-59 versus >or=60 mL/min/1.73 m(2) (P < 0.0001; OR = 2.5), thrombolytics (P = 0.01; OR = 2.7), clopidogrel loading dose >300 mg (P < 0.0001; OR = 4.2), and systolic blood pressure during PCI (P < 0.0001; OR = 1.03 per mm Hg). In-hospital deaths included 5 of 34 patients (15%) with major bleeding, none of 253 patients (0%) with minor bleeding, and none of 347 patients (0%) with no bleeding (P < 0.0001). Hospital duration was 11.0 days in patients with major bleeding, 3.4 days in patients with minor bleeding, and 1.8 days in patients with no bleeding (P < 0.0001).
