Abstract

OBJECTIVES: Hypoalbuminemia is associated with a poor prognosis in patients with end-stage renal disease, chronic ischemic heart disease, heart failure (HF), and stroke. We aimed to investigate its prognostic value in patients with acute ST-segment elevation myocardial infarction (STEMI) treated by a primary percutaneous coronary intervention (p-PCI). MATERIALS AND METHODS: We retrospectively enrolled 1706 patients with STEMI treated by p-PCI. We prospectively followed up the patients for a median duration of 40 months. RESULTS: On admission, hypoalbuminemia (<3.5 g/dl) was present in 519 (30.4%) patients. The incidence of final TIMI grade 3 flow (84 vs. 91.4%, P<0.001) was lower in the patients with hypoalbuminemia. In-hospital mortality (9.4 vs. 2%), HF (20.2 vs. 8.6%), and major bleeding (6 vs. 2.5%) rates were significantly higher in patients with hypoalbuminemia. However, in-hospital stroke and reinfarction rates were similar in both groups. At long-term follow-up (median duration: 42 months), all-cause mortality (23.3 vs. 8.4%, P<0.001), reinfarction (11.6 vs. 7.7%, P=0.013), stroke (2.6 vs. 1.1%, P=0.031), and advanced HF (13.3 vs. 6.1%, P<0.001) rates were significantly higher in patients with hypoalbuminemia. In the Cox proportional hazard model, hypoalbuminemia was determined as an independent predictor of long-term mortality [hazard ratio 2.98, 95% confidence interval 1.35-6.58, P=0.007) and development of advanced HF (hazard ratio 2.96, 95% confidence interval 1.44-6.08, P=0.003). CONCLUSION: Hypoalbuminemia on admission is a strong independent predictor for long-term mortality and development of advanced HF in patients with STEMI undergoing p-PCI.
