COVID-19 patients who were hospitalized, but not yet requiring intensive care, showed a 30% reduction in the risk of death within 30 days when given a treatment-strength dose of blood thinners compared with patients who received a lower, preventative-strength dose, according to a recent study published in the Journal of the American College of Cardiology and presented as a late-breakling trial at the American College of Cardiogy (ACC) 2023 annual meeting.[1]

The study, known as the FREEDOM-COVID trial, initially set out to explore the impact of high-dose blood thinners on overall combined outcomes, to include any of the following: risk of death from any cause, need for hospitalization in an intensive care unit (ICU), blood clot, or stroke within 30 days. However, after finding that there was no significant difference in combined outcomes for patients who received the higher treatment-strength dose versus the lower preventative-strength dose, the researchers went on to explore the impact on each of the individual outcomes, discovering the lower 30-day morbidity rates. 

What they found was a 4.9% 30-day morbidity rate for patients receiving the higher dose, compared with 7% for those receiving the lower dose. Additionally, the patients on the higher dose were significantly less likely to need a breathing tube than those on the lower dose, with respective rates of 6.4% versus 8.4%. 

“Although our study did not reach its primary endpoint, it has shown that patients admitted to the hospital for COVID-19 who are not yet critically ill, but who have early signs of lung damage caused by the virus, substantially benefit from a higher dose of blood-thinning medication to stop disease progression, prevent the need for lung intubation, and prevent death, without a significant increase in the risk of bleeding,” said Valentin Fuster, MD, PhD, president of Mount Sinai Heart, physician-in-chief of Mount Sinai Hospital, and the study’s principal investigator.
