D-dimer is a marker of fibrin formation in the blood. Fibrin is a protein involved in the clotting of blood. Rupture of a coronary plaque and subsequent thrombosis marks the core transition from stable coronary artery disease to an acute heart attack. Previous studies reported higher D-dimer concentrations in heart attack patients than for control subjects reflecting that D-dimer is a plasma marker of activated blood clotting. Increased D-dimer concentration during admission for heart attacks predicted major adverse cardiac events during hospitalization. Researchers in Switzerland reported that 3 mg of melatonin reduced stress responses and lowered D-dimer activity. The research suggests that the blunting effect of melatonin on the procoagulant response to acute psychosocial stress is clinically meaningful. Indeed, melatonin resulted in a 20% reduction in stress-induced D-dimer change. In humans, platelet aggregation in vitro was inhibited by melatonin suggesting a dose-response effect. Melatonin may be useful for bodybuilders because it reduces stress and blood coagulation.
