This study investigates the association between long-term exposure to low-concentration air pollution and cardiovascular hospitalizations among US Medicare beneficiaries aged ≥65 years between 2000 and 2016 using a double negative control approach. Positive associations were observed between PM2.5, NO2, and warm-season O3 and hospitalization rates for stroke, heart failure, and atrial fibrillation, even in low-pollution areas. These findings suggest a need for stricter national air quality standards.
