Abstract:
Objective To assess the effect of anemia on long-term outcomes in patients with acute coronary syndrome(ACS) undergoing pereutaneous coronary intervention(PCI). Methods In 3136 patients presenting with ACS,636 patients were anemic. The clinical features, mortality and major cardiocerebral events including non-fatal acute myocardial infaret,revascularization and non-fatal cerebral stroke were compared in patients with or without anemia. The average follow-up period was 550 days. Results Anemic patients were older and had a higher percentage of comorbidities compared with nonanemic cohorts. Compared with nonanemic patients, anemic patients had higher mortality (4.7% versus 1.5% ,P <0. 001) and a higher major adverse end point events,including nonfatalmyocardial infarction, stroke and revaseularization (14.2% versus 11.0%, P = 0.032). After adjustment for comorbidities, anemia was associated with a higher risk of mortality after percutaneous coronary intervention (adjusted hazard rate ratioRR2. 166 ;95% CI 1. 298-3. 612 ;P =0.003). Conclusion Anemia before PCI is an independent factor for predicting the long-term mortality of ACS.
