Table 2 Echocardiography, and cervical ultrasonography characteristics of subjects according to the level of blood pressure variability (n = 144)

From: Visit-to-visit blood pressure variability is a marker of cardiac diastolic function and carotid atherosclerosis

  1. Data are means ± standard deviation or n (%). Low, middle, and high variability are defined as the lowest (<8.29 mmHg), middle (8.29–10.99 mmHg), and highest (>10.99 mmHg) tertiles of the standard deviation of systolic blood pressure, respectively.
  2. E, early ventricular filling velocity; A, late ventricular filling velocity; e’, early diastolic mitral annular velocity; LVMI, left ventricular mass index; max-IMT, maximum intima-media thickness.
  3. aAnalysis of covariance.
