Boxplots showing the comparison of left atrial strain. In comparison to the control group, the hypertension group’s LA strain values were lower, and there was a statistically significant difference between the two groups. LASr, left atrial reservoir longitudinal strain, LAScd, left atrial conduit longitudinal strain; LASct, left atrial contractile longitudinal strain; LASr-c, left atrial reservoir circumferential strain; LAScd-c, left atrial conduit circumferential strain; LASct-c, left atrial contraction circumferential strain
