This study is looking at how exposure to World Trade Center (WTC) particulate matter (tiny particles) might lead to heart, lung, and blood vessel problems (cardiorespiratory and vascular dysfunction). Researchers are studying 100 FDNY rescue and recovery workers who were exposed to WTC particulate matter. The goal is to understand how this exposure affects your body by measuring specific markers in your blood, such as Heme Oxygenase-1 (HO-1), Glutathione, and Total Antioxidant Capacity (TAC). These measurements will be taken over a period of up to one year to see how they change. This is an observational study, meaning researchers will collect information without giving any specific treatments.

Study design

This is an observational study with a planned enrollment of 100 participants. It is not a treatment study, but rather aims to understand the effects of past WTC exposure.

What's involved

Participants will have their levels of Heme Oxygenase-1, Glutathione, and Total Antioxidant Capacity measured over a period of up to 365 days.

Compensation

Not stated in the trial record.

Follow-up

Participants will be followed for up to 365 days, based on the primary endpoint timeframes.
