[Initial-onset stenocardia: characteristics of the blood coagulation system and fibrinolysis as reaction to physical exertion].

Blood coagulation and fibrinolysis were studied at rest and during bicycle ergometry in 45 patients with angina of new onset (ANO). Fourteen chronic coronary patients and 20 subjects, free of coronary heart disease or coronary atherosclerosis, were taken as controls. Fibrinolysis tended to be depressed in resting ANO patients. Potential fibrinolysis depended on the clinical pattern of the disease and was particularly depressed in patients with severe ANO. Stress did not activate fibrinolysis in patients with vasospastic angina and high basal plasminogen activator level at rest.
