1 in 100 heart disease deaths are tied to days with extremely hot or cold temperatures, according to a new study.
additional deaths out of every 1,000 cardiovascular deaths analyzed were attributed to extreme temperature days, the study found.as 2.2 additional deaths experienced by heart disease patients on extreme hot days, while 9.1 additional deaths were experienced on extreme cold days.
This escalating risk applied to multiple common cardiovascular conditions, but was especially pronounced for people with heart failure. On extreme hot days, 2.6 additional deaths were experienced by heart failure patients, while 12.8 additional deaths were experienced by heart failure patients on extreme cold days — a respective 12% and 37% greater risk of death compared to moderate climate days.
In cities like Baltimore, researchers categorized extreme hot and cold temperatures as exceeding 86°F and dropping below 20°F.Haitham Khraishah, a co-author of the study and cardiovascular disease fellow at the University of Maryland School of Medicine and University of Maryland Medical Center, told Axios in an email that their work highlights the need for adaptation measures, particularly for "vulnerable individuals with pre-existing cardiovascular diseases.
"Our study underscores the urgent need to develop measures that will help our society mitigate the impact of climate change on cardiovascular disease," said Khraishah.Although study authors link the effects of climate change to the extreme temperatures influencing increased mortality rates, winters have warmed in 97% of 238 U.S.
