Haptoglobin (Hp) is a haemoglobin-binding acute phase protein with three genetic types: Hp 1-1, Hp 2-1, Hp 2-2. We investigated 45 patients during the first 48 hours of acute myocardial infarction, and studied determinant factors and clinical correlates. Upon hospital admission, serum haptoglobin concentration was increased (1.95 +/- 0.94 g/l, mean +/- SD, P < 0.001) versus the reference population (0.97 +/- 0.46 g/l, n = 107), independent of haptoglobin type: 1.84 +/- 0.64 g/l (Hp 1-1, n = 11) (P < 0.01), 1.98 +/- 0.79 g/l (Hp 2-1, n = 25) (P < 0.001), 1.98 +/- 1.58 g/l (Hp 2-2, n = 9) (P < 0.001). Moreover, during the first hours of hospitalization, a temporal lowering of haptoglobin was observed suggesting acute haemolysis, independent of the haptoglobin type. Minimal serum haptoglobin was reached 9.6 +/- 5.8 hours after admission. The amplitude of the haptoglobin decrease correlated with initial serum haptoglobin (r = 0.78) and was more pronounced (P < 0.05) in men (0.53 +/- 0.57 g/l) than in women (0.18 +/- 0.17 g/l). Decrease of serum haptoglobin did not correlate with infarct size (based on creatine kinase-MB release). Out of the other acute phase proteins measured upon admission, only C-reactive protein was significantly increased (P < 0.05). During the next 36 hours, haptoglobin increased as a result of the acute phase response to myocardial injury. Our findings suggest that acute myocardial infarction is also preceded by an acute phase response, characterized by an initial high haptoglobin and followed by a temporal haptoglobin decrease due to haemolysis.
