English summary
Severe hypertension (grade III and grade IV)
A study on the clinical course in 117 patients in
Landspítalinn Medical Department 1957-1971
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 Uni-
versity Hospital in Reykjavík med. Depart.) during the
years 1957-1971.
During this period 117 patients were found to have
S.H. according to the grading of Keith and Wagener (20
patients with grade IV end 97 with grade III).
It was found that relatively fewer patients with S.H.
were admitted during the last 5 year period (1967-1971)
compared to the two previous 5 year-period (1957-
1966).
The cases were analysed according to sex and age
distribution, blood urea, electrocardiographic changes,
heart size (by x-ray) and blood pressure readings at the
time of admission.
In relation to the above mentioned factors the inc-
idence and type of complications, survival time and
causes of death were evaluated.
The main causes of death were cerebrovascular
accidents (26,6%), myocardial infarction (22,8%) and
uremia (22,8%).The survival calculations were done by
the decremental method aim taken from patient age less
than 66 years.
Approximately 50% of the men and 60% of the wom-
en had a 5 year survival. Elevated blood urea values and
signs of left ventricular hypertropphy in the electrocard-
iogram at the time of diagnosis of S.H. had an unfavor-
able influence on length of survival.
