Study on Left Atrial Function in Patients with Early Left Ventricular Remodeling in Essential Hypertension Based on Two-Dimensional Speckle Tracking Technology

Abstract

Objective: To use two-dimensional speckle tracking imaging (2D-STI) to analyze the functional changes of the left atrium before hypertrophic changes in the left ventricular configuration in the early stage of hypertension and to explore the clinical value of this technology in evaluating the changes of left atrial characteristics in patients with hypertension. Methods: 70 cases of patients with essential hypertension who met the requirements of this study after clinical diagnosis and routine ultrasound examination were recruited and divided into two groups according to the Ganan method: 38 cases in the left ventricular standard remodeling group, 32 cases in the left ventricular concentric remodeling group, and 40 healthy people with matched age and sex were randomly selected as the control group. The mean peak strains and strain rates of the left atrial systole, early diastole, and late diastole of each group were obtained using 2D-STI. The above parameters and indicators were used for comparative analysis. Results: Compared with the healthy control group, the values of peak strains and strain rates during early diastole were statistically different in both remodeling groups; compared with the standard remodeling group, the values of peak strains and strain rates in all periods were significantly different in the concentric remodeling group (P < 0.05). Conclusion: 2D-STI can be more sensitive and convenient to reflect the characteristic changes of left atrial myocardium in patients with early essential hypertension.
