Left atrial function in patients with coronary artery disease: Role of 2D strain. État d’avancement du travail

Abstract

Introduction Left ventricular (LV) dysfunction in patients with coronary artery disease (CAD) is shown by strain and strain rate imaging. However, left atrium (LA) function in such patients has been little studied by this method and impairment of atrial function in CAD due to ischemia has not been clearly evaluated. We aimed to evaluate left atrial function in patients with CAD and to determine whether 2D strain can be helpful to detect CAD in these patients. Method Seventy patients with CAD, with normal-size LA (LA diameter\xa0≤\xa04.0\xa0cm, volume max index\xa0 Results Clinical and conventional echocardiographic parameters, including Doppler measurements, did not differ significantly between the two groups. LAs S/SR and LAe SR were lower in patients than in healthy subjects (P\xa0 Fig. 1 ). Conclusion Our results suggest that LAs S/SR may be a usuful parameter to identify patients with CAD.
