Air pollution continues to be a large problem around the nation, and a new study finds its effects could spell trouble for people with heart conditions. Researchers from Rice University in Houston, Texas, recently discovered patients with heart problems could be more likely to go into cardiac arrest on days when air pollution levels are higher than normal.
Scientists came to this conclusion after comparing cardiac arrest incidents that occurred outside of a hospital setting, with the air quality reports of Houston between 2004 and 2011. More than 11,000 incidents took place over the course of this time, while occurrences increased on days in which air pollution levels were high. More specifically, cardiac arrest risk increased by 4.4 percent for every 20 parts per billion of above average pollution.
This is alarming, especially since North America alone accounts for 6 percent of the world's greenhouse gas emissions, according to a joint reports conducted by the Environmental Integrity Project, EarthJustice and the Sierra Club. People suffering from heart conditions might want to consider installing medical grade air purifiers like the Airgle PurePal MultiGas AG950 into their homes to avoid certain issues on a daily basis, but especially on days when air pollution is high.
