A new study carried out by researchers from the University of Louisville that was published December 5, 2018 in JAHA the journal of the American Heart Association suggests that living in areas with lots of greenery from plants and trees may offer protection against cardiovascular disease (CVD) like heart attacks and strokes.
Previous studies have linked seniors who live near greenery to a reduced risk for depression, reduced risk for stress and anxiety, reduced need for medicines, a reduction in pain thresholds and improved attention spans. Also, there were studies suggesting an association between proximity to greenery and lower numbers of cardiovascular disease events. A study from China even suggests that living near green areas can protect seniors against frailty. However, no one ever before tried to find exactly what living near greenery does to the body and for this new study the researchers actually did blood and urine tests on participants in the study over a five year period to see just how greenery might protect against cardiovascular disease.
The Cross-sectional Study
The participants were 508 people who were in an outpatient preventive cardiology clinic at the University of Louisville for people who were at high risk for cardiovascular events. Most of them already had been diagnosed with CVD and 75% suffered from high blood pressure and 60% from elevated cholesterol. However, many of them had incorrect addresses and it was not possible to test them for proximity to green spaces, so in the end only 408 were able to be included in the study. The researchers tested their blood and urine from October 2009 to December 2014 to find signs of blood vessel injuries and risks for heart disease and strokes. They gleaned information about the greenery where they lived from satellite imaging derived normalized difference vegetation index (NDVI) in zones with radii of 250 m and 1 km surrounding the participants’ residences. Most of the participants lived in areas of low greenery in northwestern Jefferson County, Kentucky, but the majority of them lived in single-family residential homes with lots that contained both grasses and trees.
Ongoing exposure to greenery leads to good cardiovascular health:
- They had lower levels of oxidative stress.
- They had a better angiogenic profile. Angiogenesis is the process whereby new blood vessels form from those already in existence.
- They had better sympathetic stimulation of the heart and blood vessels.
- Women, in particular and people without a prior history of heart attacks or who do not take beta blockers may benefit by being close to green places as they showed a very significantly strong association between proximity to greenery and urinary levels of epinephrine
- Evaluating how much exposure people get to greenery may help to see if they are at risk for cardiovascular events like heart attacks and strokes.
