Abstract
Background: Measures of left atrial (LA) function have demonstrated prognostic value in relation to incident atrial fibrillation.
Aims: This study aimed to investigate the relationship between measures of LA function and the risk of incident atrial fibrillation (AF) in outpatients with HFrEF.
Methods: Subjects were retrospectively included from a HF clinic and followed using the Danish National Patient Registry. Measures included LA emptying fraction (LAEF), peak atrial longitudinal strain (PALS), and peak atrial contractile strain (PACS). Prognostic value was assessed with Cox proportional hazards regressions. Effect modification by sex, valve disease, and LA enlargement was assessed using interaction terms.
Results: The final study population consisted of 452 subjects (mean age 65.5±11.8 years, male sex 70.1%) free from AF at baseline. During a median follow-up of 9.4 years [IQR: 5.2, 12.7], 118 (26.1%) developed AF. These subjects exhibited higher LAVi, while LAEF, PALS, and PACS were all significantly lower. All three measures of LA function were significantly associated with incident AF in univariable and adjusted Cox regression analysis (Adjusted analysis: LAEF: HR 1.03 per 1% decrease, 95% CI 1.02-1.04, p=0.009, PALS: HR 1.06 per 1% decrease, 95% CI 1.04-1.09, p=0.037, PACS: HR 1.07 per 1% decrease, 95% CI 1.03-1.10, p=0.021). The prognostic value of LAEF was modified by sex and valve disease (p for interaction=0.007 and 0.041, respectively), while the value of PACS was modified by valve disease (p for interaction=0.011).
Conclusion: Impaired PALS, LAEF, and PACS were all associated with an increased risk of incident AF in outpatients with HFrEF.
期刊介绍:
European Heart Journal – Cardiovascular Imaging is a monthly international peer reviewed journal dealing with Cardiovascular Imaging. It is an official publication of the European Association of Cardiovascular Imaging, a branch of the European Society of Cardiology.
The journal aims to publish the highest quality material, both scientific and clinical from all areas of cardiovascular imaging including echocardiography, magnetic resonance, computed tomography, nuclear and invasive imaging. A range of article types will be considered, including original research, reviews, editorials, image focus, letters and recommendation papers from relevant groups of the European Society of Cardiology. In addition it provides a forum for the exchange of information on all aspects of cardiovascular imaging.
