Using air filters to slow heart disease progression

Slowing Atherothrombosis Progression through Indoor Air Filtration: A Crossover Trial in Hispanic and non-Hispanic Adults with Ischemic Heart Disease History

['FUNDING_R01'] · UNIVERSITY OF SOUTHERN CALIFORNIA · NIH-10854852

This study is looking at whether using affordable air purifiers at home can help lower harmful air pollution and improve heart health for people with a history of heart disease, including both Hispanic and non-Hispanic adults.

What this research studies

This research investigates how using indoor air filtration can reduce fine particulate pollution (PM2.5) exposure and its impact on heart disease progression. Participants will use low-cost air purifiers in their homes, and the study will measure changes in various heart disease biomarkers over time. The trial will include diverse groups of Hispanic and non-Hispanic adults with a history of ischemic heart disease, focusing on both immediate and long-term effects of air filtration on cardiovascular health.

Who could benefit from this research

Good fit: Ideal candidates are Hispanic and non-Hispanic adults with a history of ischemic heart disease living in areas with high levels of air pollution.

Not a fit: Patients without a history of ischemic heart disease or those living in areas with low air pollution may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved heart health and reduced risk of cardiovascular events for patients exposed to harmful air pollutants.

How similar studies have performed: Previous studies have shown promising short-term benefits of air filtration on cardiovascular health, but this is one of the first to assess long-term effects.
