Comparison of once and twice daily administration of captopril plus hydrochlorothiazide on 24 h blood pressure levels.

The anti-hypertensive effect of captopril 50 mg plus hydrochlorothiazide 25 mg, given once or twice daily, was investigated by 24 h monitoring in hypertensive patients in a controlled, randomized, double-blind, cross-over trial. Ten patients with blood pressure (BP) greater than 160 and/or 95 mm Hg after a 15 day placebo period, were randomly assigned to one of two treatments, in which they either received the combination once daily in the first month, twice daily in the second and once daily in the third (Treatment Group A) or twice daily in the first month, once daily in the second month and twice daily in the third month (Treatment Group B). The anti-hypertensive effect of the drug combination was assessed by 24 h monitoring using a Dinamap 845 to establish mean BP levels and circadian curves. After 1 month the twice daily administration was more effective than the once daily, but after 2 months, and throughout the third month, there was no difference in the anti-hypertensive efficacy of the combination given either once or twice daily.

[Physical and psychological risk factors of ischemic heart diseases. Apropos of a prospective survey in Marseilles].

The results of a survey carried out in Marseilles between 1972 and 1979 are reported. A common protocol was used to compare results with two other surveys performed conjointly in Paris and Brussels. The protocol was designed with special emphasis on the psychological factors with respect to the risk factors for ischaemic heart disease (IHD). Seven hundred and eighty six men in a Marseilles administrative department, aged 40 to 60 years (mean age 48.5 +/- 4.5 years) were followed-up for 74 months. Apart from cardiovascular clinical examination with measurement of height, weight, blood pressure and ECG recording, the initial check-up included serum cholesterol, triglycerides and glucose determination and a study of psychological risk factors based on the Bortner's scale for the evaluation of type A profile, and on a questionnaire : the SHEPI for evaluation of the N score (neuroticism). The annual IHD incidence was 9.5% with 4.2% of major events (death or infarction), and 5.3% of minor events (angina pectoris, suggestive ECG changes). Age, tobacco consumption, average systolic blood pressure, serum cholesterol and obesity index were higher in patients who became ill than in those who remained healthy, but overall and separate analysis of major and minor events showed no significant difference apart from age. On the other hand, the study of increased risk according to the level of each of these major factors gave significantly positive results except for the serum glucose level. The correlations between incidence of IDH and the value of each risk factor were not always the same according to the clinical expression (major or minor events). Psychological factors also differed according to the clinical expression of IHD : the Bortner scale was higher in patients developing IHD than in healthy subjects, and higher in those who suffered major events than in those who suffered minor events. On the other hand, the N score was higher in patients with minor events than in those suffering major events. These differences which were not statistically significant in the Marseilles study alone, became significant in the Franco-Belgian cooperative study. The increased risk with the number of associated factors (including psychological) is significant from the association of 2 factors, but only in the fifth decade.(ABSTRACT TRUNCATED AT 400 WORDS)

[Screening for blood glucose abnormalities and coronary heart disease through routine annual examination (author's transl)].

The authors address the two following questions: 1) Is detection of glycoregulation disorders possible from data yielded by routine annual examination (7,923 subjects)? 2) Do further investigations, carried out in a subdivision of subjects selected according to the risk of cardiovascular disease (n = 1,232), show a difference in the distribution of risk factors and risk indicators between patients and "healthy" individuals? Analysis of the results of this transversal study demonstrates a fact that is well-known concerning diabetes: even mild hyperglycemia (greater than or equal to 6 Mmol/l) is significantly correlated to age, excess weight and high systolic blood pressure. In both male and female subjects, there is a strong correlation between mean blood glucose concentration and the other biologic parameters that were studied (blood pressure, serum cholesterol, LDL/HDL cholesterol). Conversely, no correlation was found with smoking habits or with the intake of various dietary components. These results indicate that age, excess weight and increased blood pressure are simple data which are suggestive of abnormal glycoregulation. Comparison of risk factors and risk indicators in patients and "healthy" subjects showed significant differences for age, smoking habits and systolic blood pressure only. Glycemia, cholesterolemia and obesity were similar in both groups. These findings are evidence of the high risk in the subjects considered as "healthy", in whom the degree of atherosclerosis cannot be ascertained. Atherosclerosis in "healthy" individuals can certainly not be overlooked: in subjects with normal blood pressure, fundus examination showed a similar proportion of abnormalities in patients and "healthy" individuals.
