Researchers at eBioMedicine project that climate change will significantly increase the risk of cardiovascular disease (CVD) mortality in China, with human-induced warming potentially causing up to 90% of heat-related CVD deaths by 2090.
By Dr. Liji Thomas, MDApr 21 2024Reviewed by Benedette Cuffari, M.Sc. A new study published in the journal eBioMedicine aims to predict the extent to which climate change may impact the risk of cardiovascular disease mortality in China.
Due to climate change, the global temperature at the earth's surface has risen by 1.15 °C above that in the pre-industrial era. Previous studies have reported an adverse impact of climate change on overall mortality that is dependent on age, sex, and cause of death, as well as deaths due to CVD. These projections were based on the Coupled Model Intercomparison Project Phase 6 , which is under the World Climate Research Programme . WCRP examines natural climate change and the combined scenario with both natural and anthropogenic impacts on the climate.
Study findings The mean annual temperature at the DSPs varied from 12.6 to 28.4 °C, during which time about 330,000 CVD deaths occurred. The death rate among CVD patients followed a J-shaped curve beyond a critical minimum temperature. The most significant increase relative to baseline temperature was in the South and East of China.
Conclusions "This study provides evidence that human activities will amplify future heat-related cardiovascular mortality burden.”

Researchers propose host-directed therapy to stimulate immune system to eliminate tuberculosisTuberculosis (TB) is the world's deadliest bacterial disease and most commonly affects the lungs. Recent years have seen an increase in drug-resistant TB cases leaving many patients with limited treatment options. The only vaccine—BCG—is relatively ineffective at preventing TB in adults. New treatments are urgently needed.
