196 LÆKNABLAÐIÐ period (1967-1971) compared to the two previous 5 year-periods (1957-1966). The cases were analysed according to sex and age distribution, blood urea, electrocardio- graphic changes, heart size (by x-ray) and blood pressure readings at the time of admis- sion. In relation to the above mentioned factors the incidence and type of complications, sur- vival time and causes of death were evaluated. The main causes of death were cerebro- vascular accidents (26,6%), myocardial infarc- tion (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 women had a 5 year survival. Elevated blood urea values and signs of left ventricular hypertrophy in the electrocardiogram at the time of diagnosis of S.H. had an unfavorable in- fluence on length of survival.
