Left Atrial Strain Is Reduced in Patients with Atrial Fibrillation, Stroke or TIA, and Low Risk CHADS2 Scores

摘要: Background Left atrial (LA) strain as a marker for discrimination of risk stroke and transient ischemic attack (TIA) in patients with fibrillation low-risk CHADS 2 scores (≤1) has yet to be examined. Methods Patients fibrillation, or TIA, ≤ 1 before their events were identified retrospectively from large single-center registry compared age-matched gender-matched controls. Antihypertensive use echocardiographic parameters including chamber volumes left ventricular mass LA peak negative positive rate between groups. Results Fifty-seven meeting entry criteria identified. demonstrated significantly lower ejection fractions, larger dimensions, volume indexes (24.4 ± 11.9 vs 32.3 13.3 mL/m , P  = .012) Both (−3.2 1.2% −6.9 4.2%, Conclusions In scores, reduced is potentially sensitive maker increased TIA. These results suggest that may have potential tool helping guide the decision against oral anticoagulation this group patients.
