Extreme temperatures are becoming significant cardiovascular risks, potentially leading to heart attacks and strokes. A report by Weill Cornell Medicine and the American Heart Association highlights the growing danger of heat and cold, particularly for vulnerable populations. Coordinated action is needed to mitigate these risks.
- 01Extreme heat events are increasing in frequency and intensity, potentially leading to more heat-related deaths than cold-related deaths.
- 02Older adults, pregnant individuals, infants, outdoor workers, and low-income populations are particularly vulnerable to temperature extremes.
- 03The healthcare system contributes approximately 8.5% of greenhouse gas emissions in the U.S., necessitating changes in practices to reduce its carbon footprint.
- 04Research is needed to understand how temperature thresholds affect those at risk for cardiovascular issues and the interaction of medications with heat stress.
- 05Policy leaders can help by ensuring affordable energy costs for air conditioning and providing cooling centers during heatwaves.

A recent statement from experts at Weill Cornell Medicine and the American Heart Association warns that extreme temperatures are increasingly threatening cardiovascular health. The report highlights that while cold weather historically caused more cardiovascular deaths, rising heat events are becoming more frequent and severe, potentially leading to a higher number of heat-related fatalities. Vulnerable groups such as older adults, pregnant individuals, and outdoor workers are at heightened risk. Dr. Arnab Ghosh, a lead author, emphasizes the need for coordinated action across research, clinical practice, and policy to protect public health. The healthcare sector, which contributes significantly to greenhouse gas emissions, must adapt its practices to mitigate climate impacts. Recommendations include more research on temperature thresholds for cardiovascular risks and improving access to cooling resources. Urban planning, such as planting trees to create shade, is also essential for reducing heat exposure in communities. The authors call for immediate action to address these challenges, stating that heat is a pressing problem that requires innovative solutions.
