title: Effects of blood pressure and sex on heart-vessel coupling in essential hypertension.
abstract: OBJECTIVE
  This study aimed to investigate the impact of blood pressure and sex on heart-vessel coupling in patients with essential hypertension via ultrasound.
  
  
  METHODS
  We studied 76 patients with essential hypertension (48 males and 28 females) and 65 healthy controls (33 males and 32 females). Coupling parameters were obtained using ultrasound technology combined with brachial artery blood pressure measurement.
  
  
  RESULTS
  The Ea and Ees were higher in the hypertension group than in the control group (P < 0.01), with no statistically significant difference in Ea/Ees between the two groups (P >0.05). After subjects were classified by sex, the Ea and Ees of males and females in the hypertension group were higher than those in the control group (P < 0.05 or P < 0.01), while the Ea/Ees was lower in hypertensive females than in control females (P < 0.05).
  
  
  CONCLUSIONS
  In female patients with essential hypertension, heart-vessel coupling was easily damaged, and systolic blood pressure was associated with heart-vessel coupling damage to some extent.
