P-Wave Indices and the Risks of Incident Atrial Fibrillation and Ischemic Stroke in Black Adults: The Jackson Heart Study.

ABSTRACT:

Background

Atrial cardiomyopathy, defined as adverse changes to the cardiac atria, is an emerging risk factor for atrial fibrillation (AF). Despite the disproportionate burden of AF-related complications in Black adults, the relationship between electrocardiographic (ECG) measures of atrial cardiomyopathy, referred to as P-wave indices (PWIs), and outcomes remains largely unknown in this population.

Methods

In 4900 participants without AF at baseline from the JHS (Jackson Heart Study), a prospective cohort study of Black adults, we assessed atrial cardiomyopathy using PWIs from resting 12-lead ECGs: PR interval, P-wave duration, P-wave axis, and P-wave terminal force in V1 (PTFV1). Cox proportional hazards models evaluated associations of PWIs with incident AF and ischemic s
