[Severe hypertension (grade III and grade IV). A study on the clinical course in 117 patients in Landspítalinn Medical Department 1957-1971. 1974].

The aim of this study was to evaluate the incidence, complications, survival time and causes of death of patients with severe hypertension (S.H.) (grade III and grade IV) who were admitted to Landspítalinn (The University Hospital in Reykjavík med.

[The effects of different settings on outcome when screening for high blood pressure.].

Introduction: It has become increasingly popular to offer blood pressure measurements under circumstances that differ from the usual setting, for example measurements in supermarkets, pharmacies, at exhibitions etc. It is well known that environmental factors as well as doctor and patient relationship can affect blood pressure measurement. This must be considered in the diagnosis and treatment of hypertension.

[Hypertension in the elderly - changing attitudes toward treatment].

Raised blood pressure in the elderly is a frequent finding and is not a benign occurence. It should not be viewed as a normal or inevitable consequence of aging. Recent major intervention trials against hypertension in the elderly have showed clear benefits from actively lowering elevated arterial pressure in this group of patients and also in those with isolated systolic hypertension.

Recreational exercise and cardiovascular status in the rural community of Tecumseh, Michigan.

Background: Because of population stability, Tecumseh, a rural community in Michigan, was the site of health surveys over a period of three decades.

Methods: In the recent survey anthropometrics, blood pressure (BP), blood chemistry, echo/Doppler cardiac exam, personality and exercise questionnaires were collected on site.

Results: In this rural community 70% of subjects (447 men, 410 women, average age 30 years) do not engage in recreational exercise.

Reflex sympathetic activation induces acute insulin resistance in the human forearm.

Inferences about the association between sympathetic overactivity and insulin resistance have been drawn from the infusion of sympathomimetic amines in supraphysiological doses. We used the isolated perfused human forearm to investigate the effect of reflex-induced sympathetic nervous system activation on the peripheral utilization of glucose in the skeletal muscles of 14 healthy men. Local hyperinsulinemia in the forearm (132 +/- 25 microunits/mL for 90 minutes) induced a significant increase in the utilization of glucose from baseline (16.
