BACKGROUND: In-hospital bleeding after percutaneous coronary intervention is associated with increased mortality. We studied the impact of bleeding severity, defined as magnitude of Hgb (hemoglobin) reduction from baseline (ΔHgb), on the risk of death and other adverse events.
METHODS AND RESULTS: We studied the association between ΔHgb, baseline characteristics, and outcomes among 7608 patients in the ADAPT-DES registry (Assessment of Dual Antiplatelet Therapy With Drug-Eluting Stents) who had information on Hgb values before and after they underwent successful percutaneous coronary intervention. Post-percutaneous coronary intervention, 5985 (78.7%) patients had a drop in Hgb, with 2684 patients (35.3%) having a ΔHgb <1.0 g/dL, 2338 (30.7%) ≥1.0 to <2.0 g/dL, 745 (9.8%) ≥2.0 to <3.0 g/dL, 145 (1.9%) ≥3.0 to <4.0 g/dL, and 73 (1.0%) ≥4.0 g/dL. The risk of dying within 2 years was 3.3% with <1.0 g/dL ΔHgb, 3.4% with ΔHgb ≥1.0 to <2.0 g/dL, 3.7% with ΔHgb ≥2.0 to <3.0 g/dL, 4.1% with ΔHgb ≥3.0 to <4.0 g/dL, and 9.8% with ΔHgb ≥4.0 g/dL (P=0.03). The risk of major adverse cardiac events (defined as cardiac death, myocardial infarction, or stent thrombosis) was higher for patients with ΔHgb ≥4.0 g/dL (adjusted hazard ratio, 3.39; 95% confidence interval, 1.97-5.83; P<0.001) and for patients with ΔHgb ≥3.0 to <4.0 g/dL (adjusted hazard ratio, 2.17; 95% confidence interval, 1.34-3.53; P=0.002).
CONCLUSIONS: Among patients who undergo successful percutaneous coronary intervention, bleeding events that result in ΔHgb ≥4.0 g/dL are associated with a considerably increased risk of dying.
