Comparison of left atrial function between the two groups as assessed by 4 chambers strain indices, (A) comparison of LA strain between the two groups. A1 Comparison of the rate of change of LA strain between the two groups (B) comparison of SRs between the two groups. B1 Comparison of the rate of change of SRs between the two groups (C) comparison of SRe between the two groups. C1 Comparison of the rate of change of SRe between the two groups. D Comparison of SRa between the two groups. D1 Comparison of the rate of change of SRa between the two groups. Variables are expressed as mean ± standard deviation. *P < 0.05 SRs, strain rate during ventricular contraction; SRe, ventricular strain rate during early diastole; SRa, atrial strain rate
