Left ventricular disease as a risk factor for adverse outcomes and stroke recurrence in patients with embolic stroke of undetermined source.

ABSTRACT:

Background

Severe left ventricular (LV) systolic dysfunction (ejection fraction [EF] < 30%) is a known cardiovascular risk factor and a major cause of cardioembolism. However, less severe forms of LV disease (LVD), such as mild-to-moderate LV dysfunction and LV wall motion abnormalities (LVWMAs), are considered potential minor cardiac sources in Embolic Stroke of Undetermined Source (ESUS), but their role is underexplored. This study aims to evaluate the prevalence of LVD in ESUS and its association with adverse vascular events and mortality.

Methods

Retrospective, single-center study including consecutive ESUS patients admitted from January 2016 to May 2024. LVD was defined as either global systolic dysfunction (LV ejection fraction 30%-49%) or regional LVWMAs, unrelated to
