A recent study published in the Journal of the American College of Cardiology highlights a concerning link between long-term exposure to PM2.5, a harmful air pollutant from wildfire smoke, and an increased risk of heart failure.

The research indicates that as PM2.5 levels rose over a two-year period, so did the likelihood of developing heart failure, particularly affecting older adults.

Notably, the study found that women, Medicaid-eligible individuals, and those living in lower-income areas exhibited a higher susceptibility to the risks associated with wildfire smoke.

Looking ahead, experts warn that climate change could lead to longer wildfire seasons and more frequent events, with projections suggesting that by the end of the century, 74% of the globe may be affected.

These findings underscore the urgent need for enhanced environmental policies and healthcare preparedness to safeguard communities against the escalating threat posed by wildfire smoke.
