HEAL Green Heart Louisville Project: Greenness and Heart Health

This study, called the HEAL Green Heart Louisville Project, is looking at how your environment, specifically "greenness" (like parks and trees), affects your heart health and overall well-being. Researchers want to see if adding more green spaces can act as a therapeutic intervention. They will measure changes in arterial stiffness (how flexible your arteries are) over two years to see if this intervention is successful. You may be able to join if you are between 30 and 70 years old, live in the study area, and meet other health criteria. The current status of the study is unclear, but it plans to enroll 835 people.

Study design
This is an interventional study planning to enroll 835 participants. It aims to understand the impact of greenness on health.
What's involved
You would have your arterial stiffness measured at the beginning of the study and again after two years.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for two years after their initial measurements.
