Listen "Environmental Exposure as Intervention: HEPA Filtration and Blood Pressure Near Traffic Corridors | JACC Deep Dive"

Episode Synopsis

In this Deep Dive, Editor-in-Chief Dr. Harlan Krumholz explores a pragmatic, randomized crossover trial testing whether in-home HEPA filtration can reduce blood pressure in adults living near high-traffic roadways. The findings offer early insights into how targeted environmental interventions may influence cardiovascular risk—especially among individuals with elevated baseline systolic blood pressure.
