Abstract
Bleeding risk stratification is an unresolved issue in older adults. Anemia may reflect subclinical blood losses that can be exacerbated after percutaneous coronary intervention . We sought to prospectively determine the contribution of anemia to the risk of bleeding in 448 consecutive patients aged 75 or more years, treated by percutaneous coronary interventions without concomitant indication for oral anticoagulation. We evaluated the effect of WHO-defined anemia on the incidence of 1-year nonaccess site-related major bleeding. The prevalence of anemia was 39%, and 13.1% of anemic and 5.2% of nonanemic patients suffered a bleeding event (hazard ratio 2.75, 95% confidence interval 1.37 to 5.54, p = 0.004). Neither PRECISE-DAPT nor CRUSADE scores were superior to hemoglobin for the prediction of bleeding. In conclusion, anemia is a powerful predictor of bleeding with potential utility for simplifying tailoring therapies.
