Serum haptoglobin in cases of ischemic heart diseases

Serum haptoglobin (Hp) was estimated in 76 cases of ischemic heart diseases (IHD) and 151 healthy individuals. A statistically significant rise in Hp level was observed in IHD cases. The rise was independent on the age and blood type of the cases but was more predominent in males as compared to females. The increase in Hp level was noticed after the third day of coronary attack and peak level was obtained between the 7th to 9th day. Hp level was closely related to the degree of myocardial damage. No rise was seen in cases of angina whereas maximum rise was noticed in patients with multiple infarcts. Hp phenotype pattern in IHD cases was not different from that of control cases.
