... in the elderly subjects compared with almost no change in the young subjects (from 82 ± 8 to 84 ± 7 mmHg). In the elderly subjects a progressive increase in total peripheral resistance (from 114 ± 14% to 146 ± 29%) was found, compared with an initial rapid increase in total peripheral resistance (126 ± 18% after...

... patients. 5. Total peripheral resistance was inappropriately elevated in hypertensive pregnancy, except in the oxprenolol-treated group. 6. There was no reduction in heart rate or cardiac output in the group treated with β - adrenoreceptor blocking agents. These factors, in combination with normal...

... is sustained by a high total peripheral resistance. 4. The mean blood volume, plasma renin concentration and creatinine clearance were similar in eight hypertensive and 16 normotensive patients. Therefore the hypertension of stable renal transplant recipients is not related to blood volume expansion, elevated...

... were determined before, during and after training sessions. 3. BFB training resulted in a significant reduction in mean arterial pressure (from 116 ± 4·6 to 101 ± 2·5 mmHg) mediated through a fall in total peripheral resistance; cardiac output, heart rate, intravascular volume and plasma renin activity...

... to increase with age in the controls, whereas plasma noradrenaline in the hypertensive subjects showed a wide range of responses without any fixed relationship with age. 3. The cardiac index was significantly greater in the labile hypertensive subjects than in the controls, whereas total peripheral resistance...

... volume was noted in all three groups. At that time no difference in total peripheral resistance was found between the groups. 4. The results are consistent with the hypothesis that the renomedullary antihypertensive substance(s) mitigates hypertension by preventing a hypertensive haemodynamic response...

...R. Fagard; A. Amery; T. Reybrouck; P. Lijnen; L. Billiet; J. V. Joossens 1. Plasma renin concentration, intra-arterial pressure, cardiac output and total peripheral resistance have been studied in 50 patients with essential hypertension and normal renal function. 2. Total peripheral resistance...
