Résumé
The association between short-term exposure to ambient air pollution and blood pressure has been inconsistent, as reported in the literature. This study aimed to investigate the relationship between short-term ambient air pollution exposure and patient-level home blood pressure (HBP). Patients with chronic cardiovascular diseases from a telehealth care program at a university-affiliated hospital were enrolled as the study population. HBP was measured by patients or their caregivers. Hourly meteorological data (including temperature, relative humidity, wind speed, and rainfall) and ambient air pollution monitoring data (including CO, NO A total of 253 patients and 110,715 HBP measurements were evaluated in this study. On multivariate analysis, demographic, clinical, meteorological factors, and air pollutants significantly affected the HBP (both SBP and DBP). All 5 air pollutants evaluated in this study showed a significant, nonlinear association with both home SBP and DBP. Compared with demographic and clinical factors, environmental factors (meteorological factors and air pollutants) played a minor yet significant role in the regulation of HBP. Short-term exposure to ambient air pollution significantly affects HBP in patients with chronic cardiovascular disease.

BACKGROUND
The association between short-term exposure to ambient air pollution and blood pressure has been inconsistent, as reported in the literature.
OBJECTIVE
This study aimed to investigate the relationship between short-term ambient air pollution exposure and patient-level home blood pressure (HBP).
METHODS
Patients with chronic cardiovascular diseases from a telehealth care program at a university-affiliated hospital were enrolled as the study population. HBP was measured by patients or their caregivers. Hourly meteorological data (including temperature, relative humidity, wind speed, and rainfall) and ambient air pollution monitoring data (including CO, NO
RESULTS
A total of 253 patients and 110,715 HBP measurements were evaluated in this study. On multivariate analysis, demographic, clinical, meteorological factors, and air pollutants significantly affected the HBP (both SBP and DBP). All 5 air pollutants evaluated in this study showed a significant, nonlinear association with both home SBP and DBP. Compared with demographic and clinical factors, environmental factors (meteorological factors and air pollutants) played a minor yet significant role in the regulation of HBP.
CONCLUSIONS
Short-term exposure to ambient air pollution significantly affects HBP in patients with chronic cardiovascular disease.
