In this study we assessed the role of psychological factor in the etiology of coronary vasospasm using the Cornell Medical Index (CMI), focusing attention on the relationship between stress and serum magnesium (Mg). The study subjects consisted of 25 patients with variant angina (VA), 32 with old myocardial infarction without vasospasm (OMI), and 34 healthy men (controls). On a neurosis-discriminative diagram of CMI, areas I and II were considered as normal and areas III and IV were considered to be a neurotic disorder. The stress test included exercise and a quiz. Exercise test was performed in 8 patients with VA, 6 with OMI, and 5 controls, and a quiz was given to 4 patients with VA. Plasma catecholamines [noradrenaline (NA), adrenaline (Ad), dopamine], aldosterone, adrenocorticotropic hormone (ACTH) and serum electrolytes (Mg, Ca, Na, K, Cl) were measured before and after exposures to stress. The following results were obtained: 1) Of the patients with VA, 40.0% were categorized as area III or IV, compared to 18.7% of the patients with OMI, and 2.9% of the control subjects. 2) Among patients with VA, 64.0% exhibited anxiety states compatible with a psychological disorder. 3) NA and Ad were increased after exercise stress. 4) Serum Mg and Ca were also increased after exposure to exercise stress in all groups, and the degrees of these changes were correlated to the exercise intensity. The %delta Mg/%delta NA ratio, a parameter of the effect of catecholamine on the serum Mg, was greater in patients with VA than in those with OMI and the controls.(ABSTRACT TRUNCATED AT 250 WORDS)
