Effects of a medication on blood vessel function and organ injury in heart surgery patients

The Effects of Soluble Guanylyl Cyclase Stimulation on Perioperative Vascular Reactivity and Organ Injury in Cardiac Surgery

Phase 4 Interventional Vanderbilt University Medical Center · NCT05812755

What this trial studies

This clinical trial investigates the impact of a medication called vericiguat, a soluble guanylyl cyclase stimulator, on vascular function and markers of kidney and brain injury in patients undergoing elective cardiac surgery. Participants will be randomly assigned to receive either vericiguat or a placebo, and their vascular function will be assessed using ultrasound and direct arterial relaxation tests. Additionally, researchers will measure markers of kidney and brain injury in plasma and urine to evaluate the medication's effectiveness compared to placebo. The study aims to uncover the mechanisms behind post-surgical kidney and brain function issues.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older scheduled for elective open-heart surgery.

Not a fit: Patients with severe renal impairment, significant liver dysfunction, or those undergoing specific types of surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved vascular function and reduced organ injury in patients undergoing heart surgery.

How similar studies have performed: Other studies have shown promise with soluble guanylyl cyclase stimulators in improving vascular function, making this approach both relevant and potentially impactful.
