Studies on cerebrovascular stroke. III. Long-term prognosis and clinical findings in a follow-up study of a stroke material.

The present paper reports the third part of an investigation of first-time cerebrovascular strokes occurring in people under the age of 70. The long-term prognosis for 214 patients discharged alive from hospital after the acute phase of the stroke is presented. The clinical and laboratory findings for 114 patients alive at the time of a follow-up examination 32 months after the stroke are discussed. The long-term prognosis could be predicted best by a score, calculated from the neurological findings on admission after the acute stroke. Recurrence of stroke was associated with a very high mortality. Forty-five per cent of the patients who survived the first month had died by the time of follow-up. About 15% were able to return to normal life or go back to work. There was a trend among patients originally severely handicapped to improve their performance ability. Factors influencing the chances for rehabilitation are discussed. Among the survivors there was a strikingly high percentage of patients with overt diabetes or decreased glucose tolerance, of patients with arteriosclerotic heart disease and patients with elevated serum triglyceride levels. These findings are discussed.

Stroke before fifty. Experiences from a five-year study.

Thirty-seven patients below the age of 50, with an acute first-time cerebrovascular lesion have been studied. Some form of predisposing factor was present in nearly all cases. There was a remarkably high incidence of cardiovascular and cerebrovascular disease among the parents of the stroke victims. Only 50% of the patients with hypertension known prior to the stroke had received adequate treatment. There were six females on oral contraceptives. The immediate mortality, i.e. within one month, was 35% essentially caused by a very high initial mortality among patients with cerebral haemorrhage. The patients were checked after 30 months. At this time, 16 patients were still alive and 11 able to perform some sort of work. Among the survivors there was a high incidence of diabetes and impaired glucose metabolism, to judge from intravenous glucose tolerance tests. The chances of survival and vocational rehabilitation seem to be fairly good, compared with higher age groups, thus urgently calling upon the resources of the community for active therapeutic measures and training. Individuals with hypertension and impaired glucose tolerance, with heredity for vascular disease and diabetes seem to be especially at risk for early stroke. Health surveys should be directed to tracing these subjects early.

Perspectives of adenylate kinase activity and glutathione concentration in cerebrospinal fluid of patients with ischemic and neoplastic brain lesions.

Adenylate kinase (AK) activity and glutathione concentration were measured in cerebrospinal fluid (CSF) on three different occasions after the ictus in 16 patients with cerebral infarction. All patients displayed an unambiguous AK activity in their CSF within 48 h after the ictus while glutathione was present in 10 of the 16 patients. The mean AK activity among these patients was reduced by about 60% after 1 week and an additional smaller reduction took place after 3-4 weeks. The glutathione concentration in CSF of these patients showed a similar curve profile with time. The 9 patients who showed clinical signs of improvement had significantly lower values on all occasions for both AK and glutathione than those who did not improve or deteriorated. A corresponding reduction in AK activity with time was not observed in 3 patients with cerebral malignancies. The possibility was excluded that the enhanced AK activity in CSF was the result of an increased transfer of the enzyme from the plasma compartment. Instead of causal relationship was suggested between the appearance of AK in CSF and a disturbed brain cell metabolism. Repeated analyses revealed different curve profiles for ischemic and neoplastic brain lesions. The importance of sampling and handling the CSF material under standardized conditions is emphasized.

Long-term blood pressure control with pindolol given once daily.

The antihypertensive effect of beta-adrenoceptor blocking drugs has been documented in a number of papers [10--13] and over the last 10 yr beta-receptor blockade has become a more and more frequent primary therapy for hypertension. During this time, a number of different beta-blockers with various degrees of selectivity, potency and intrinsic sympathomimetic effect have come into use. There have also been attempts to reduce the number of daily doses in beta-adrenoceptor blocking therapy while maintaining the antihypertensive effect [5]. Pindolol (Viskén) is a beta-adrenoceptor blocking agent with intrinsic sympathomimetic effect and is characterized by high potency and long duration.
