Levels of soluble fibrin monomer complexes in the course of myocardial infarction.

Plasma fibrinogen concentration, euglobulin clot lysis time, and soluble fibrin monomer complexes *-an whole blood samples with protamine sulphate were determined in healthy subjects as well as in patients with atherosclerosis, coronary insufficiency, or myocardial infarction. Fibrinogen content and soluble fibrin monomer complex levels were higher while fibrinolytic activity was lower in ipatients with atherosclerosis, coronary insufficiency, and myocardial infarction than in the healthy subjects. The blood soluble fibrin monomer complex level was significantly raised in patients with myocardial infarction as compared with patients with coronary insufficiency. These -parameters, studied during the first three weeks in cases of myocardial infarction, showed a
