title: Response of plasma lipoproteins and acute phase proteins to myocardial infarction.
abstract: Plasma concentrations of lipoprotein-lipids, apolipoprotein B (apoB) and of seven other proteins have been estimated serially in 27 patients up to three months following myocardial infarction. Results were compared with those from age- and sex-matched control subjects. At three months the mean total, low density lipoprotein (LDL) and high density lipoprotein (HDL) cholesterol concentrations were higher than those of the control subjects, whereas very low density lipoprotein (VLDL) cholesterol, total and VLDL triglyceride, and total and LDL apolipoprotein B concentrations were not significantly different. Relative to concentrations at three months total and LDL cholesterol and apolipoprotein B concentrations fell markedly, and a slight fall occurred in HDL cholesterol following infarction. VLDL cholesterol and total and VLDL triglyceride were decreased only on day one. Albumin and transferrin concentrations were higher and alpha 1-acid glycoprotein was lower at three months than in the control subjects; alpha 2-macroglobulin, caeruloplasmin, haptoglobin and immunoglobulin IgM were not significantly different. Following infarction albumin and transferrin fell, alpha 2-macroglobulin did not change, and alpha 1-acid glycoprotein, caeruloplasmin, haptoglobin and IgM rose. The changes in both lipids and protein are probably part of the general metabolic response to trauma.
