摘要: Changes in the three phases of left atrial (LA) function have not been well studied hypertension. We phasic LA by speckle tracking echocardiography (STE) Sixty-one consecutive untreated hypertension patients and 32 sex- age-matched healthy participants were included. Two-dimensional (2D) images obtained from apical four-chamber two-chamber views used for STE analysis LA. peak positive strain (39.8 ± 10.9 vs. 45.3 ± 12.7 %, p = 0.031), negative (−2.2 ± 1.5 −3.0 ± 1.9 = 0.029), conduit rate (−2.0 ± 0.5 −2.4 ± 0.6 1/s, = 0.005) significantly decreased Twenty hypertensive (32%) had diastolic dysfunction. Positive (34.8 ± 7.2 42.2 ± 11.6 = 0.012) (−1.7 ± 0.4 −2.2 ± 0.5 = 0.026) after multivariable analysis. is Decreased associated with dysfunction
