What this trial studies

This trial investigates the impact of portable air filters on indoor air quality and the functional capacity of heart failure patients with reduced ejection fraction in India. It aims to demonstrate the efficacy, feasibility, and effectiveness of these air purifiers in reducing PM2.5 levels, which are known to contribute to cardiovascular issues. The study will compare the effects of an active air purifier against a placebo filter among eligible participants. The findings could provide insights into innovative strategies for improving both environmental and cardiovascular health.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older diagnosed with heart failure with reduced ejection fraction of 40% or less within the last six months.

Not a fit: Patients who are listed for a cardiac transplant, have severe pulmonary disease, or are unable to ambulate may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved health outcomes for heart failure patients by enhancing their functional capacity through better air quality.

How similar studies have performed: While the approach of using air purifiers for heart failure patients is innovative, similar studies have shown potential benefits of improving air quality on cardiovascular health.
