Atrial Fibrillation Detected by Handheld ECG and Ischemic Stroke Risk in a 55- to 64-Year-Old Chinese Population.

ABSTRACT:

Background

Atrial fibrillation (AF) screening is recommended at age ≥65 years, but the age threshold in Asians is uncertain because of higher ischemic stroke risk <65 years.

Objectives

This study evaluated AF screening yield in a Chinese population aged 55 to 64 years, comparing stroke risk of those with and without AF, and the effect of oral anticoagulants (OAC).

Methods

Patients aged 55 to 64 years attending Hong Kong outpatient clinics underwent opportunistic handheld electrocardiogram screening. Repeat screening was performed if >1 clinic visits. Crude incidence rate ratios of ischemic stroke were determined and compared between 3 cohorts: screen-detected AF; clinically diagnosed AF; and no AF. Ischemic stroke risk for all AF categories was compared with individua
