Table 3 Odds ratio of abnormal LAVi, LAEF and LASr to determine patients with NYHA class ≥ II

From: Impact of different degrees of left ventricular strain on left atrial mechanics in heart failure with preserved ejection fraction

Variables Odds ratio (95% CI) p-value Odds ratio (95% CI) p-value
Analysis of the whole cohort     
 LAVi > 34 ml/m2 1.877 (1.063–3.314) 0.030 1.297 (0.708–2.375) 0.400
 LAEF < 50% 3.894 (2.202–6.885)  < 0.001 3.382 (1.791–6.389)  < 0.001
 LASr < 23% 2.613 (1.497–4.562) 0.001 2.064 (1.118–2.110) 0.021
Analysis of the patients with at least one CV risk factor or CAD     
 LAVi > 34 ml/m2 2.018 (1.121–3.634) 0.019 1.416 (0.757–2.646) 0.276
 LAEF < 50% 3.953 (2.197–7.114)  < 0.001 3.340 (1.751–6.370)  < 0.001

  1. A p-value < 0.05 indicates statistical significance (bold and italic)
  2. Odds ratio were adjusted for age, gender, and AF
  3. LAVi left atrial volume index; LAEF LA emptying fraction; LASr, LA strain during reservoir phase; NYHA New York Heart Association functional class
