Greenspace visitation and risk of major adverse cardiovascular events: evidence from the Houston methodist cardiovascular learning health system registry
Authors' conclusion
Mobility-derived greenspace visitation is associated with lower cardiovascular risk. These findings highlight greenspace engagement as a potentially modifiable behavioural exposure and support strategies to enhance access and utilization of greenspaces for cardiovascular prevention.
Study context
- Population
- Adults without baseline atherosclerotic cardiovascular disease in the Houston Methodist Cardiovascular Disease Learning Health System Registry (2016–2023)adults without baseline atherosclerotic cardiovascular disease
- Participants
- 1,088,866 adults
- Exposure
- Greenspace visitation and incident major adverse cardiovascular events (MACE)
- Outcome
- Incident MACE:
- Myocardial infarction
- Stroke
- Coronary revascularization
- All-cause mortality

Further findings
Cohort characteristics
- Median (SD) age
- 49 (17.6) years
- Female
- 59.9%
- Greenspace visitation varied across neighbourhoods and by demographic and socioeconomic characteristics
Dose-response of greenspace visitation and MACE (restricted cubic splines)
- Non-linear relationship with risk reductions at low-to-moderate visitation, plateauing
- 10-15 visits annually
Event-free survival (Kaplan-Meier)
- Higher event-free survival in high-visitation areas, consistent across MACE components
