Summary
Stroke patients in Sweden experienced significantly higher cerebrovascular mortality than the general population. Cerebrovascular disease remained the leading cause of death for these patients throughout the study periods.
Area of Science:
- Neurology
- Public Health
- Epidemiology
Background:
- Cerebrovascular mortality has decreased in the general Swedish population.
- Understanding long-term mortality causes in stroke survivors is crucial.
Purpose of the Study:
- To investigate the causes of death in stroke patients over an extended period.
- To compare mortality rates in stroke patients with the general population.
Main Methods:
- Population-based study of first-ever strokes in Söderhamn, Sweden.
- Analysis of three distinct time periods: 1975-1978, 1983-1986, and 1987-1990.
- Long-term follow-up (≥10 years) of 1186 patients.
Main Results:
- Cerebrovascular mortality was over 10-fold higher in stroke patients compared to the general population across all periods.
- Mortality from ischemic heart disease and other conditions was moderately elevated (3- to 8-fold).
- Mortality rates from malignant disorders were comparable to the general population.
Conclusions:
- Cerebrovascular disease was the primary cause of death for Swedish stroke patients during the 1970s and 1980s.
- Stroke survivors face substantially increased risks for cerebrovascular and other causes of mortality.
