Coronary disease & ACSCohort study
Tropical cyclones and acute coronary syndromes: a Chinese nationwide study
- Time-stratified case-crossover study
- nationwide registry
Authors' conclusion
TC exposure may increase the ACS burden by simultaneously increasing the risk of incidence and delaying treatment.
Study context
- Population
- Acute coronary syndrome (ACS) patients from a nationwide registry in mainland China, 2015–2022
- Participants
- 2,563,780 patients
- Exposure
- Tropical cyclone (TC) days vs non-TC days
- Outcome
- ACS incidence
Main finding
As reported in the abstract
ACS risk · 0-3 days after TC exposure
Increase in ACS risk after TC exposure
14% (95% CI 2% to 27%)
Observational data: associations, not effects.
Further findings
Delay in self-referral to hospital
Admission-to-catheterization time
ACS risk by subgroup
- Stronger associations among males, lower education levels and those with more ACS risk factors
