Implantable Loop Recorders in Patients with Unexplained Syncope: Does Ethnic Background Influence Diagnostic Yield?

Area of Science:

• Cardiology
• Medical Devices
• Diagnostic Tools

Background:

• Implantable loop recorders (ILRs) are crucial for diagnosing unexplained syncope.
• Optimal results depend on patient understanding and active participation.
• Investigating factors influencing ILR diagnostic yield is essential for equitable healthcare.

Purpose of the Study:

• To determine if ethnic background or mother-tongue language impacts the diagnostic yield of ILRs.
• To assess potential disparities in ILR effectiveness based on demographic factors.

Main Methods:

• A cohort study involving 94 patients undergoing ILR implantation for syncope workup in Israel.
• Data collected included demographics, ethnicity, medical history, ILR findings, and activation modes.
• Patients were categorized into Jewish (ethnic majority) and non-Jewish (ethnic minority) groups.

Main Results:

• No significant differences in recorded arrhythmias, treatment decisions, or device activation modes were observed between ethnic groups.
• Jewish patients were significantly older at implantation compared to non-Jewish patients.
• Follow-up duration was longer in the non-Jewish group.

Conclusions:

• Patient ethnicity and mother-tongue language did not influence the diagnostic yield of implantable loop recorders for unexplained syncope.
• These findings suggest ILR effectiveness is consistent across diverse patient populations.
• Further research may explore other factors influencing diagnostic outcomes.
