Summary

This study tests whether beetroot juice, which contains natural nitrates that relax blood vessels, can safely lower lung blood pressure in people with intermediate high-risk pulmonary embolism. 36 adult patients will receive either beetroot juice or a placebo for five days, alongside standard care. The main goal is to measure changes in lung artery pressure three hours after the first dose.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: nitrate-rich beetroot juice
What this could lead to: If it works, this could point toward a simple dietary supplement to stabilize patients with dangerous lung blood clots.
What could go wrong: This is a very small, early safety study with only 36 participants. It may show no benefit, and the juice could cause low blood pressure in some patients.
