Standard echocardiographic parameters
Table 2 compared baseline echocardiographic parameters between groups. Left ventricular mass index and left atrium volume index were overall balanced between AL-CA and HHD group. All the groups fall under the category of preserved LVEF. The HHD group had higher LVEF (62.00 vs 59.00, P =0.005) and lower GLS (-20.12 vs -14.44, P <0.001) than the AL-CA group. E wave, A wave, and EA ratio were similar between AL-CA and HHD group. Lateral e’ velocity was not significantly different between the two groups. Septal e’ velocity was significantly higher in HHD group than that in AL-CA group (6.00 vs 4.00, P =0.002), and average E/e’ was lower in HHD group (9.65 vs 13.04, P =0.026). Left atrial ejection fraction was significantly lower in AL-CA group than that in HHD group (48.50 vs 61.00, P <0.001).
