Authors' conclusion

Residential exposure to green space, blue space, and natural environments is associated with lower HF incidence and healthier cardiac phenotypes, independent of genetic predisposition and air pollution. Green space demonstrates the most robust cardioprotective effects.

Incident HF, 300-m buffer

Similar trends, with comparable protective associations for green space, blue space and natural environment

CMR remodelling, natural environment, 1000-m buffer

Attenuation of adverse remodelling comparable to green space effects
