Investigating heart function changes after stimulation in scar areas using the NOGA system

Changes in Regional and Global Cardiac Contractility After Stimulation in Scar Zone with the NOGA System

NA · University Hospital, Toulouse · NCT04757168

This study is testing if stimulating scar areas in the heart can improve heart function in patients who have had a heart attack and need treatment for fast heartbeats.

What this trial studies

This clinical trial aims to explore the relationship between electrical changes and mechanical contractility in cardiac scar areas following a myocardial infarction. Using the NOGA system, researchers will stimulate these scar zones to assess any resulting changes in cardiac contractility. The study focuses on patients who require ventricular tachycardia ablation due to ischemic heart disease and aims to provide insights into the effectiveness of this approach. By correlating electrical activity with mechanical function, the trial seeks to enhance understanding of post-infarction cardiac recovery.

Who should consider this trial

Good fit: Ideal candidates include patients with ischemic heart disease who are scheduled for ventricular tachycardia ablation.

Not a fit: Patients without ischemic heart disease or those contraindicated for ventricular tachycardia ablation may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for patients with myocardial infarction and ventricular tachycardia.

How similar studies have performed: While this approach is novel, similar studies have shown promising results in understanding cardiac function post-myocardial infarction.

Eligibility criteria
