Neighborhoods Flanked With Greenery Promote A Healthy Heart

People who live in leafy, green neighborhoods are at a lower risk of developing heart diseases and strokes, a study said.
Over five years, blood and urine samples were collected from 408 people of varying ages, ethnicities and socioeconomic levels, and then assessed for biomarkers of blood vessel injury and the risk of having cardiovascular disease.
The risk was calculated using biomarkers measured from blood and urine samples. The participants were recruited from the University of Louisville's outpatient cardiology clinic and were largely at elevated risk for developing cardiovascular diseases.
The density of the green spaces near the participants' residences was measured using the Normalised Difference Vegetation Index (NDVI), a tool that indicates levels of vegetation density created from satellite imagery collected by NASA and USGS.
Air pollution levels were also assessed using particulate matter from the EPA and roadway exposure measurements.
Our study shows that living in a neighborhood dense with trees, bushes and other green vegetation may be good for the health of your heart and blood vessels, said Aruni Bhatnagar, lead author of the study.
Indeed, increasing the amount of vegetation in a neighborhood may be an unrecognized environmental influence on cardiovascular health and a potentially significant public health intervention, Bhatnagar added. The findings were independent of age, sex, ethnicity, smoking status, neighborhood deprivation, use of statin medications and roadway exposure. Previous studies have also suggested that neighborhood green spaces are associated with positive effects on overall physical and psychosocial health and well-being, as well as reduced rates of death from cardiovascular and respiratory diseases, and improved rates of stroke survival, according to Bhatnagar.
