Coronary heart-disease after treatment of hypertension.

Abstract Within a group of 1026 men aged 47-54, cause-specific death-rates and the incidence of non-fatal myocardial infarction and stroke in a treatment group of 635 hypertensive men (casual systolic B.P. >175 or diastolic B.P. >115 mm Hg on two occasions) treated at a hypertension clinic were compared with those in a control group of 391 men (casual systolic B.P. >175 or diastolic >115 mm Hg on only one occasion) who remained mainly untreated during their 4·3 years of follow-up. The predicted risk of coronary heart-disease (C.H.D.) at entry, calculated by a multiple logistic function, was slightly higher in the treatment group. Total death-rate during follow-up was significantly lower in the treatment group (3·3%) than in the control group (6·1%). The difference in death-rate for C.H.D. was of the same relative order (0·8% versus 1·5%), as was the incidence of non-fatal myocardial infarction (2·8% versus 5·4%), although none of the differences reached statistical significance. However, the pooled incidence of fatal and non-fatal C.H.D. was significantly lower in the treatment group (3·6%) than in the control group (6·9%). The results suggest that antihypertensive treatment might be effective in preventing or postponing C.H.D. in middle-aged men.

Comparison of Hemodynamic Responses to Exercise in Hypertensive Patients and in Healthy Subjects Given Angiotensin

Eleven healthy subjects received an intravenous infusion of angiotensin that raised their mean arterial blood pressure to the level observed in 15 patients with untreated essential hypertension. A hem
