Insights

Left ventricular global longitudinal strain (LV GLS) predicts left ventricular reverse remodeling (LVRR) in dilated cardiomyopathy (DCM) patients. An LV GLS of -10% is optimal for identifying LVRR in DCM patients with sinus rhythm.

Area of Science:

  • Cardiology
  • Echocardiography
  • Cardiovascular Imaging

Background:

  • Dilated cardiomyopathy (DCM) frequently leads to left ventricular reverse remodeling (LVRR).
  • Left ventricular global longitudinal strain (LV GLS) is a sensitive measure of myocardial dysfunction.
  • Predicting LVRR in DCM patients with sinus rhythm is crucial for prognosis.

Purpose of the Study:

  • To evaluate if baseline LV GLS can predict LVRR in DCM patients with sinus rhythm.
  • To determine the prognostic role of LV GLS in long-term follow-up of DCM patients.
  • To identify an optimal LV GLS cut-off for predicting LVRR.

Main Methods:

  • 160 DCM patients with sinus rhythm were enrolled.
  • Retrospective analysis of medical records and echocardiographic data.
  • Multivariate Cox analysis was used to assess predictors of LVRR.

Main Results:

  • LVRR occurred in 28% of patients during a mean follow-up of 37.3 months.
  • Baseline LV GLS showed a significant correlation with follow-up LVEF (r = 0.717; p < 0.001).
  • LV GLS was an independent predictor of LVRR (HR: 1.474; p = 0.001).

Conclusions:

  • LV GLS is an independent predictor of LVRR in DCM patients with sinus rhythm.
  • An optimal LV GLS cut-off of -10% was identified for predicting LVRR.
  • Baseline LV GLS is significantly correlated with follow-up LVEF, aiding in LVRR prediction.
