Exploring the genetic factors in heart muscle disease related to pacemakers

Genetic Basis of Pacing-Induced Cardiomyopathy

Observational The Guthrie Clinic · NCT03317964

This study is trying to find out if certain genes play a role in heart muscle disease for people who have pacemakers by collecting and analyzing their saliva samples.

What this trial studies

This observational study aims to collect saliva samples from patients who have pacemakers to investigate the genetic factors associated with cardiomyopathy, a condition characterized by abnormal heart muscle. The study will extract DNA from the saliva samples to analyze genetic variations that may contribute to the development of this condition. By understanding these genetic changes, researchers hope to gain insights into the mechanisms of pacing-induced cardiomyopathy. The study focuses on patients who have been evaluated for cardiomyopathy to ensure relevant data collection.

Who should consider this trial

Good fit: Ideal candidates for this study are patients who have been assessed for cardiomyopathy and have a pacemaker.

Not a fit: Patients without adequate follow-up care to determine their cardiomyopathy status may not benefit from this study.

Why it matters

Potential benefit: If successful, this research could lead to better understanding and management of cardiomyopathy in patients with pacemakers.

How similar studies have performed: While this study explores genetic factors in a specific context, similar genetic investigations in cardiomyopathy have shown promise in understanding the disease.
