Summary
Short-term behaviors like straining, overeating, and anger can trigger hemorrhagic stroke (HS). Specific triggers, such as mahjong, are identified in Chinese populations, highlighting cultural influences on HS risk.
Area of Science:
- Neurology
- Public Health
- Epidemiology
Background:
- The immediate behavioral triggers for hemorrhagic stroke (HS) remain incompletely understood.
- Identifying these triggers is crucial for targeted prevention strategies, especially considering potential population-specific differences.
Approach:
- A case-crossover study involving 284 new-onset HS patients in China was conducted.
- Patients reported on 20 potential behavioral trigger factors (BTFs) during specific pre-onset periods.
- A literature review synthesized existing evidence on BTFs for HS.
Key Points:
- Straining for defecation, weightlifting, overeating, heavy physical exertion, and playing chess/cards/mahjong were associated with increased HS risk within 2 hours of onset.
- Critical life events were linked to increased risk 7 days prior to HS onset.
- Anger and heavy physical exertion showed increased HS risk in pooled analysis.
Conclusions:
- Several behavioral activities and emotional states are significant BTFs for HS.
- Chinese populations exhibit unique BTFs, such as specific games and life events, alongside common triggers.
- Awareness and avoidance of these BTFs, coupled with emotional regulation, can aid in HS prevention for at-risk individuals.
