Hospitalized COVID-19 patients who were taking a daily low-dose aspirin to protect against cardiovascular disease had a significantly lower risk of complications and death compared to those who were not taking aspirin, according to a new study led by researchers at the University of Maryland School of Medicine (UMSOM). Aspirin takers were less likely to be placed in the intensive care unit (ICU) or hooked up to a mechanical ventilator, and they were more likely to survive the infection compared to hospitalized patients who were not taking aspirin, The study, published today in the journal Anesthesia and Analgesia, provides “cautious optimism,” the researchers say, for an inexpensive, accessible medication with a well-known safety profile that could help prevent severe complications.
“This is a critical finding that needs to be confirmed through a randomized clinical trial,” said study leader Jonathan Chow, MD, Assistant Professor of Anesthesiology at UMSOM. “If our finding is confirmed, it would make aspirin the first widely available, over-the-counter medication to reduce mortality in COVID-19 patients.”
To conduct the study, Dr. Chow and his colleagues culled through the medical records of 412 COVID-19 patients, age of 55 on average, who were hospitalized over the past few months due to complications of their infection. They were treated at the University of Maryland Medical Center in Baltimore and three other hospitals along the East Coast. About a quarter of the patients were taking a daily low-dose aspirin (usually 81 milligrams) before they were admitted or right after admission to manage their cardiovascular disease.
