As daily temperatures climbed above 90 degrees Fahrenheit (F) (32 degrees Celsius) across the U.S., so did the rate of out-of-hospital (OHCA) cardiac arrest admissions to hospitals' intensive care units (ICUs). However, the heat didn't appear to affect the overall outcomes of people admitted for cardiac arrest during heat waves compared with other times, according to new, independent, preliminary research to be presented at the American Heart Association's Resuscitation Science Symposium 2026.

📋 Key Takeaway
Research indicates that as temperatures exceed 90°F in the U.S., there is an increase in out-of-hospital cardiac arrest admissions to ICUs, particularly among women and older adults. This study, presented at a major medical symposium, highlights the health risks associated with extreme heat. Understanding these trends is crucial for Iran, where similar climate conditions may impact public health.
🔍 Quick Context Guide
💡 Bottom Line:
Extreme heat poses significant health risks, particularly for vulnerable populations, highlighting the need for proactive public health measures.

📰 What Happened
Research presented at a medical symposium indicates that extreme heat increases out-of-hospital cardiac arrest admissions, especially among vulnerable populations like women and older adults, but does not affect overall outcomes.
- Daily temperatures exceeding 90°F correlate with increased cardiac arrest admissions to ICUs.
- The study highlights the health risks posed by extreme heat, particularly for vulnerable groups.
💡 Why It Matters
🇮🇷 For Iran: Iran is experiencing rising temperatures and may face similar health risks, making this research relevant for public health planning.
🌍 Regional: Other countries in the region may also be impacted by climate change, leading to increased health risks.
🌐 International: The findings could influence global health policies regarding climate change and its health effects.
📚 Background
Extreme heat is increasingly recognized as a public health threat, particularly for those with pre-existing health conditions. Understanding its effects can help mitigate risks.
