Effect of left ventricular ejection fraction Spectrum on 1-Year mortality in patients with acute ischemic stroke or transient ischemic attack.

ABSTRACT:

Aims

We aimed to investigate the association of the left ventricular ejection fraction (LVEF) spectrum with 1-year clinical outcomes in patients with acute ischemic stroke (AIS) or transient ischemic attack (TIA).

Methods

In a prospective registry for the Third China National Stroke Registry (CNSR-III), AIS or TIA patients with echocardiography records during hospitalization were recruited. All LVEFs were categorized into intervals of 5% in width. The lowest and highest intervals are ≤40% and >70%, respectively. The primary outcome was all-cause death at 1 year. Cox proportional hazards regression analysis was performed to investigate the association between baseline LVEF and clinical outcomes.

Results

This analysis included a total of 14,053 patients. In total, 418 p
