These biomarkers rose in response to air pollution in people who already had heart disease, but not in patients who were heart disease free, showing that heart failure patients are not as able to adapt to changes in the environment,” said Benjamin Horne, principal investigator of the study and professor of research at Intermountain Health.
Researchers specifically looked at blood tests for 115 different proteins that are signs of increased inflammation in the body.
These spikes were caused by either wildfire smoke in the summer, or during a winter inversion, where air pollution is trapped when warm air holds pollution closer to the ground.
Researchers found that two inflammatory markers — CCL27 and IL-18 — were elevated in heart failure patients, but did not change in those without heart disease, indicating that such air pollution events put more strain on the bodies of patients who already have heart problems.
These findings “give us some information about mechanisms in people with heart failure who are having inflammation and suggest they’re not as capable in responding to acute inflammation as people who are healthy,” said Dr Horne.
Heart failure patients need to take extra precautions during times when air pollution is high.
