Can a heart failure drug ease chest pain from artery spasms?

NCT ID NCT06415227

First seen Jul 29, 2026 · Last updated Jul 30, 2026 · Updated 1 time

Summary

This phase 2 trial tests whether vericiguat, a drug already used for heart failure, can improve blood vessel function in people with vasospastic angina—a type of chest pain caused by spasms in the heart's small arteries, not by blockages. About 57 adults with frequent angina symptoms despite current treatment will receive vericiguat and a placebo in separate 10-week periods. The study measures changes in skin blood flow as a marker of vessel health, aiming to see if the drug can help relax the arteries and reduce symptoms.

What this could mean

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

Active substance
vericiguat, a drug that stimulates an enzyme to improve blood vessel relaxation
What this could lead to
If it works, this could point toward a new treatment option for people with vasospastic angina who continue to have symptoms despite current therapy.
What could go wrong
This is a small, early-phase trial with only 57 participants. The drug may cause low blood pressure or dizziness, and its benefits for angina symptoms are not yet proven.
