Extreme heat drives CV death risk in men
Researchers analyzed daily maximum heat index levels for 3,108 counties in the contiguous U.S. during summer months (May-September) from 1979 to 2017, using data from the National Environmental Public Health Tracking Network. Researchers also assessed monthly CV mortality rates for adults using data from the National Center for Health Statistics. For each county, an extreme heat day was defined as a maximum heat index of at least 90°F and greater than or equal to the 99th percentile of the maximum heat index in the baseline period (1979-2007) for that day.

From 2008 to 2017, each additional extreme heat day during summertime months was associated with a 0.13% (95% CI, 0.04-0.21; P = .005) increase in monthly adult CV mortality rates. This association was significant for men (0.21%; 95% CI, 0.08-0.33) but not women. Among race/ethnicity subgroups, this association was significant for Black adults (0.27%; 95% CI, 0.1-0.45), but not for white or Hispanic adults.

The study suggests that extreme heat may have a disproportionate impact on the cardiovascular health of certain populations.
