Arterial plasma noradrenaline and adrenaline concentrations before, during and after an attack of pain, induced first by constant supine exercise and then by multistep atrial pacing, were determined in four patients with coronary occlusion disease and stable angina pectoris. An identical protocol was applied to a patient with atypical precordial pain (anxiety state) and normal coronary arteriograms. When compared, the results led to the following conclusions: 1) during supine exercise arterial plasma catecholamine concentrations, particularly noradrenaline, progressively increase, reaching highest values in temporal coincidence with the onset or the peak of pain, 2) during multistep atrial pacing-induced angina no significant changes of arterial plasma catecholamine concentrations are seen. These data, obtained from the same patients, further emphasize that the application of atrial pacing to the study of pathophysiology of angina pectoris and for evaluating antianginal drugs, especially if interfering with adrenosympathetic system activity, must be considered with caution.

The primary aim of the study was to evaluate practice differences in reported morbidity in the second and third national morbidity surveys (1970/71, 1981/82) and to discuss their cause. A secondary aim concerned the validation of trends identified from analysis of the data from the total populations in the practices. Altogether 19 practices participated in both surveys. Annual prevalences (that is, the number of patients attending the general practitioner with a condition per 1000 persons at risk) were examined for: all conditions; each of three categories of seriousness of disease; diseases aggregated by chapter of the International classification of diseases; and each of 130 rubrics of the disease classification. Annual prevalence for 'all conditions' was approximately the same for males in both surveys, whereas for females there was an increase. In both sexes, annual prevalence for 'serious conditions' increased slightly and for 'trivial conditions' increased substantially. For 'intermediate conditions', there was a modest decrease in males. In the analysis at ICD chapter level, substantial increases in prevalence occurred in infectious diseases, nervous system diseases, circulatory diseases, genitourinary diseases, musculoskeletal diseases, symptoms, signs and ill-defined conditions, injuries and poisonings. Decreases were found in blood diseases, mental disorders and digestive diseases. Among 130 individual conditions examined, increased annual prevalence was found for mumps, fungal infections, hypothyroidism, diabetes, gout, senile dementia, angina, left heart failure, catarrh, hay fever and asthma, orchitis, acne, osteoarthritis and for some symptoms. Decreases were found for iron deficiency anaemia, anxiety state, refractive errors, haemorrhoids, chronic bronchitis, functional disorders of the stomach, carbuncle and skin infections.(ABSTRACT TRUNCATED AT 250 WORDS)

In this study, the role of psychological make-up was assessed as a risk factor in the etiology of vasospasm in variant angina (VA) using the Cornell Medical Index (CMI). Study subjects consisted of 15 patients with VA; 32 with effort angina or old myocardial infarction having no vasospasm (EA + OMI); and 34 healthy men. For a neurosis discriminative diagram, the areas I and II were judged as normal and the areas III and IV were judged compatible with a neurotic disorder. Correlation of serum lipid levels with psychological factors was attempted. 1. Among the VA patients, 46.7% belonged to the areas III and IV, as compared to 18% of the patients with EA + OMI, and 2.6% of the healthy subjects. 2. Seventy-three percent of the VA group showed anxiety states indicating a correlation with a psychological disorder. 3. A majority of the VA patients had a variety of psychological symptoms unrelated to myocardial ischemia. 4. Total cholesterol, triglycerides, LDL cholesterol, serum uric acid and the atherogenic index were all lower in the VA group than in the EA + OMI group. 5. In the EA + OMI group, triglycerides, serum uric acid and the atherogenic index were higher in the psychological group than in the non-psychological group. However, total cholesterol, LDL cholesterol and HDL cholesterol were lower in the former than in the latter group. It was concluded that an anxiety state constitutes a contributing background for developing VA and it was speculated that such an anxiety state may lead to an exaggerated secretion of stress hormones, resulting in vasospasm of the coronary arteries.
