BackgroundThe impact of haemoglobin concentrations on clinical outcomes is still a controversial issue. To determine the association between haemoglobin concentrations on admission and clinical outcomes and the related factors, this study was performed in a Chinese hospital.

FindingsWe conducted a retrospective study on 1394 Chinese patients with acute myocardial infarction. Patients were categorized according to the haemoglobin concentration on admission, and data were evaluated to determine whether there was an association between the haemoglobin concentrations on admission and 30-day in-hospital MACEs major cardiovascular events. Patients with hemoglobin values between 141 and 150 g-L were used as the reference, the MACEs increased as hemoglobin concentrations fell below 140 g-L or rose > 150 g-L, with an adjusted OR odds ratio of 5.9695% CI confidence interval 2.00 to 17.68, p = 0.0013, 4.391.37 to 14.08, p = 0.0128, 3.991.46 to 10.92, p = 0.0071, 3.191.27 to 8.05, p = 0.0139, 2.370.94 to 6.01, p = 0.0687, 2.110.66 to 6.74, p = 0.2065, 2.010.60 to 6.68, p = 0.2559 in patients with haemoglobin concentrations <100 g-L, 101-110 g-L, 111-120 g-L, 121-130 g-L, 131-140 g-L, 151-160 g-L, and >160 g-L respectively. Partial correlation analysis showed that age, albumin and creatinine were significantly associated with hemoglobin concentration.

ConclusionsOur results demonstrated that haemoglobin concentration affected MACEs in patients with acute myocardial infarction, and that haemoglobin concentration was associated with age, albumin and creatinine.
