9. Blood Pressure Response to Physical Activity in Hypertensive Subjects at Different Times of the Day

Author

Krönig, B., Knappen, F., Dufey, K., and Wolff, H. P.

Abstract

1. Active orthostasis causes a fall of systolic blood pressure in the morning; this fall was more extensive in severe arterial hypertension. 2. Everyday physical activity produces a marked rise of systolic blood pressure, which is higher at noon and in the evening than in the morning; the hypertensive response is somewhat greater in WHO II and III, than in WHO I, grades of hypertension. 3. In studies on blood pressure behaviour in hypertensive subjects the circadian variability not only of the blood pressure at rest but also of the blood pressure response to various stimuli has to be considered.

10. Beziehung zwischen Blutdruckvariabilität, Schwere der Hypertonie und Plasmareninaktivität

Author

Reinhardt P, Jahnecke J, U. Walter, B. Krönig, Dufey K, and R. Müller

Abstract

Die Bedeutung der Plasmareninaktivitat bei der essentiellen Hypertonie ist insgesamt ein multifaktorielles Problem und in vielen Details umstritten. So wurde 1970 unter anderem eine signifikante Korrelation von Schwere und Variabilitat der Hypertonie zur Plasmareninaktivitat durch Schalekamp u. Mitarb. beschrieben.

15. [The effect of prindolol on the blood-pressure profile of hypertensives (with special consideration of response to exercise and plasma-renin activity) (author's transl)].

Abstract

Using microcatheter blood pressure telemetry, the pressure-lowering effect of prindolol (Visken), a beta-blocking drug, was tested at a dose of 10 mg three time daily by mouth in eight patients with essential hypertension (WHO stage II) and low to normal plasma-renin activities. After about ten days of treatment, the hypertensive reaction to everyday physical exercise (walking, climbing stairs, bicycle ergometry) was especially favourably affected. The average blood-pressure reduction at rest was 18.6/12.1 (systolic/diastolic), on stair climbing 41.5/17.2 mm Hg.
