[Means of differential diagnosis between angina pectoris and neurocirculatory dystonia]

Plasma somatotropic hormone and cortisol were measured at rest, at the peak of physical stress and 2 hours after the discontinuation of exercise in 15 normal male subjects, 18 male patients with neurocirculatory dystonia and 69 with angina pectoris. The determination of one-dimensional hyperplanes of plasma STH and cortisol during and after exercise allows one to distinguish anginal patients from those with neurocirculatory dystonia and make a diagnosis in patients with nonspecified chest pains.
