Clinical Trial Summary

Geriatric patients are at high risk of cardiovascular complications, and for the development of atrial fibrillation. Often atrial fibrillation exists in these patients without specific symptoms, and could therefore remain unknown. Furthermore, concerns exist about the bleeding profile of anticoagulation in the very elderly or frail patients.

This study applies opportunistic screening for atrial fibrillation as advised in the latest ESC Guideline on the diagnosis and management of atrial fibrillation. Furthermore, multiple bleeding risk scores will be applies, to better assess the bleeding risk in very elderly or frail patients.

Recruitment information / eligibility

• Status: Active, not recruiting
• Enrollment: 1075
• Est. completion date: June 30, 2026
• Est. primary completion date: October 26, 2022
• Accepts healthy volunteers: No
• Gender: All
• Age group: 65 Years and older

Eligibility

Inclusion Criteria:

All newly referred patients of 65 years and older that visit geriatric outpatient services are eligible (including Fall clinic, Memory clinic, Pre-operative geriatric assessment clinic, or any other geriatric outpatient clinics that are led by a geriatrician).

Exclusion Criteria:

• The patient has a pacemaker or implantable cardioverter defibrillator.

• The patient is known with a severe dementia, MoCA = 15 points.

• The patient has a severe tremor, from whatever cause, and thus is unable to use the PPG based smartphone AF detection algorithm.

Related Conditions & MeSH terms

• Atrial Fibrillation
• Frailty
• Major Bleed

Intervention

Device:
• HeartSDK
The photoplethysmography (PPG) application enables patients to perform a finger tip heartbeat measurement and automatic analysis
