OBJECTIVE: To examine the incidence and inter-relationships between admission hyperglycemia, anemia and impaired renal function and its impact on clinical outcomes in patients with ST-elevation myocardial infarction (STEMI) treated with primary PCI.
METHODS: The study group comprised 1880 patients with STEMI treated with primary PCI, enrolled in a prospective registry.
RESULTS: The primary endpoint of in-hospital death occurred in 88 (4.7%) patients. Hyperglycemia (glucose >11.1mmol/L) was present in 352(18.7%), anemia (hematocrit <36% women, <39% men) in 396(21.1%), and increased serum creatinine (> or =1.2mg/dL women, > or =1.3mg/dL men) in 423(22.5%) patients. 1026(54.6%) subjects had none of the triad risk factors. Two overlapping conditions were observed in 207(11%) and 3 in 40(2.1%) patients. Compared to the expected distribution, an increased prevalence was observed in patients with zero, two or three risk factors, and decreased prevalence was present in patients with one risk factor (p<0.001). In multivariable model including important baseline risk factors and the whole triad risk factors, hyperglycemia, anemia, and increased serum creatinine were independently associated with the primary outcome (hazard ratio (HR); 95% confidence interval (CI): 2.67; 1.56-4.55, and 2.03; 1.19-3.46, and 1.72;1.01-2.93, respectively). Adjusted HR (95% CI) for the incidence of the primary outcome associated with 1, 2 and 3 examined risk factors as compared to 0 of the risk factors was 2.7(1.4-5.4), 5.4(2.6-8.3) and 8.3(3.0-23.2), respectively.
CONCLUSIONS: Hyperglycemia, anemia, and impaired renal function are independently of each other related to in-hospital death in patients with STEMI treated with primary PCI. The triad risk factors cluster and accumulation of these risk factors is related to stepwise, additive increase of risk of in-hospital mortality.
