How breathing mustard or chlorine gas harms blood vessels and the heart over time

Vascular injury and repair predict divergent late onset cardiovascular morbidities after chlorine and sulfur mustard exposure

NIH-funded research University of Colorado Denver · NIH-11162407

What this research studies

If you were exposed to these chemicals or are worried about past exposure, the researchers are comparing sulfur mustard and chlorine to understand why they cause different long-term effects. They will track blood vessel injury, clotting, blood pressure, and heart function over time using laboratory tests, tissue studies, and measures of inflammation and calcium handling. The team will look for blood or tissue markers and repair pathways that predict delayed problems like pulmonary hypertension and heart dysfunction. Findings could help doctors identify survivors at risk and point to new treatment targets.

Who could benefit from this research

Good fit: People who were exposed to sulfur mustard or chlorine gas, or survivors with late-onset lung or cardiovascular symptoms such as pulmonary hypertension, high blood pressure, or heart dysfunction, would be the most relevant candidates.

Not a fit: People without exposure to these chemical agents or whose heart or lung conditions have unrelated causes are unlikely to benefit directly from this work.

Why it matters

Potential benefit: Could identify markers and mechanisms that help prevent or treat delayed lung and heart disease after mustard or chlorine inhalation.

How similar studies have performed: Prior work has documented acute clotting and lung injury after high-dose exposures, but studying delayed vascular injury and progressive cardiovascular disease after lower-dose sulfur mustard is a less-explored, relatively novel area.
