Global and Regional Cardiovascular Mortality Attributable to Nonoptimal Temperatures Over Time
Authors' conclusion
Nonoptimal temperatures substantially contribute to cardiovascular mortality, with heterogeneous spatiotemporal patterns.

Main finding
As reported in the abstract
Annual CV deaths attributable to nonoptimal temperatures
- Annual CV deaths associated with nonoptimal temperatures
- 1,801,513 (95% empirical CI 1,526,632-2,202,831)
- Share of total CV mortality
- 8.86% (95% empirical CI 7.51%-12.32%)
- Deaths per 100,000 population
- 26
- Cold-related share
- 8.20% (95% empirical CI 6.74%-11.57%)
- Heat-related share
- 0.66% (95% empirical CI 0.49%-0.98%)
Further findings
Regional variation
- Highest excess mortality rates in Central Asia and Eastern Europe
Temporal trends · 2000 to 2019
- Cold-related excess death ratios decreased, heat-related increased; overall decline in temperature-related deaths
- Greatest reduction in Southeastern Asia, Sub-Saharan Africa and Oceania; increase in Southern Asia
- Fluctuating patterns in the Americas and several regions in Asia and Europe
