Stroke epidemiology in South Korea has shifted, with ischemic stroke now more common than hemorrhagic stroke. The study observed changes in stroke subtypes, age distribution, and sex disparities over time.
Area of Science:
- Neurology
- Epidemiology
- Public Health
Background:
- The aging population and lifestyle changes in South Korea are impacting stroke epidemiology.
- Understanding these shifts is crucial for public health strategies.
Purpose of the Study:
- To analyze the changing trends in stroke epidemiology in South Korea.
- To compare stroke characteristics between two distinct time periods.
Main Methods:
- Retrospective review of medical records for 1,124 stroke patients (1994-1996) and 1,705 stroke patients (2003-2005).
- Analysis of variables including age, sex, seasonal variation, and stroke subtype distribution.
Main Results:
- A significant reversal in stroke subtypes was observed: hemorrhagic stroke decreased from 67.9% to 40.3%, while ischemic stroke increased from 32.1% to 59.6%.
- Stroke incidence shifted to older age groups (sixties and seventies) in the later period.
- Gender disparities increased for ischemic stroke and intracerebral hemorrhage, with males increasingly affected.
Conclusions:
- Stroke epidemiology in South Korea has evolved, particularly in subtype distribution.
- Further multicenter prospective studies with stroke registries are needed to establish national trends.

Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
