The Effect of Ozone Treatment on Coronary Flow Reserve in Patients With Heart Failure Having Reduced Ejection Fraction

Ekrem Bilal Karaayvaz·interventional·Posted Aug 21, 2025·Updated Sep 26, 2025

In Brief

A clinical study evaluating Ozone treatment for Heart Failure and Reduced Ejection Fraction. Completed, enrolled 60 participants across 1 site.

Detailed Summary

The goal of this clinical trial is to determine the effect of ozone treatment in heart failurte with reduced ejection fraction. The main questions it aims to answer are: Does ozone treatment have beneficial effects in heart failure patients? What medical problems do heart failure patients have when taking ozone treatment? Researchers will compare ozone treatment in patients with heart failure to ozone treatment in patients with no heart failure (control group) as well as before and after the ozone treatment in patients with heart failure to see if ozone works to treat heart failure. Participants will: Give blood samples Take 6-minute walk test Be perfomed Echocardiography with CFR (Coronary Flow Reserve) Take drug ABC or a placebo every day for 4 months Visit the clinic twice a week for ozone treatment for 2 months Give blood samples (after the ozone treatment) Take 6-minute walk test (after the ozone treatment) Be perfomed Echocardiography with CFR (Coronary Flow Reserve) (after the ozone treatment)

Interventions

Ozone treatmentdrug

Ozone treatment was administered to study group only. 90 ml of blood was collected into a vacuum sterile glass bottle (Ozonosan). To prevent clotting, 10 ml of 3.8% Na Citrate solution was added to the glass vial. The blood to citrate volume ratio is 9:1. After blood collection, the O3 concentration is ozonized to 20-50 mcg/ml. After at least 5 minutes of mixing, ozonized blood was infused over 20 minutes. Ozone/oxygen mixture was administered intravenously. Ozone therapy was administered twice a week for a total of 16 sessions.
