Insights

Global longitudinal strain (GLS) shows promise as an indicator for hypertension treatment. Its improvement rate surpassed other echocardiographic measures, suggesting GLS may be an ideal index for monitoring antihypertensive therapy effectiveness.

Area of Science:

  • Cardiology
  • Cardiovascular Imaging
  • Hypertension Research

Background:

  • Primary hypertension is a major cardiovascular disease risk factor.
  • Current indicators for left ventricular end-diastolic pressure are suboptimal.
  • Novel markers are needed for effective hypertension management.

Purpose of the Study:

  • To evaluate Global Longitudinal Strain (GLS) as a potential indicator for left ventricular end-diastolic pressure in hypertension.
  • To assess the efficacy of antihypertensive treatment using echocardiographic parameters, including GLS.
  • To compare the treatment response of GLS with other diastolic function indices.

Main Methods:

  • Echocardiography was performed on 73 hypertensive patients and 37 controls.
  • Key parameters measured included Peak mitral valve flow velocity (E, A), E/A, left atrial volume index (LAVl), tissue Doppler (PW-TDI) peak velocities (e'), E/e', and GLS.
  • Measurements were taken before, one month, and three months after antihypertensive treatment.

Main Results:

  • Left ventricular end-diastolic pressure (LVEDP) correlated positively with GLS and negatively with E/e'.
  • Hypertensive patients exhibited lower e' and higher GLS, E/e', and LAVI compared to controls.
  • GLS and E/e' improved significantly after treatment, with GLS showing a superior improvement rate.

Conclusions:

  • Global Longitudinal Strain (GLS) demonstrated a significantly higher improvement rate than e' and E/e' after one and three months of antihypertensive treatment.
  • GLS may serve as a potential ideal index for monitoring patients undergoing antihypertensive therapy.
  • These findings offer valuable insights for future research in hypertension management.
