研究目的:

主要目的:评估在稳定标准降压治疗基础上,加用SGLT2i治疗10-12周对高血压患者早期LA功能(LASr)的改善情况。 次要目的:评估对左房容积指数等超声参数的影响。评估对神经激素、炎症标志物水平的影响。  

Objectives of Study:

The main objective is to evaluate the improvement of early LA function (such as LASr) in hypertensive patients with the addition of SGLT2i for 10-12 weeks on the basis of stable standard antihypertensive treatment. Secondary objective: To evaluate the impact on ultrasound parameters such as left atrial volume index (LAVI). Evaluate the effects on the levels of neurohormones (NT-proBNP) and inflammatory markers (CRP, IL-6).

Group:

Interventional group

Sample size:

干预措施:

在现有标准降压治疗(SoC)基础上,每天加用一片 SGLT2i 药物(达格列净 10mg 或恩格列净 10mg)。其他降压药物尽量维持稳定,若需按指南调整需详细记录。

干预措施代码:

Intervention:

In addition to standard antihypertensive therapy (SoC), one tablet of SGLT2 inhibitor (dapagliflozin 10 mg or empagliflozin 10 mg) was administered daily. Other antihypertensive medications were to be kept as stable as possible; any adjustments according to guidelines required detailed documentation.

随机方法(请说明由何人用什么方法产生随机序列):

本研究将采用中央随机化系统进行分层区组随机化。按是否合并糖尿病、基线LASr三分位数、基线收缩压(>=140/<140 mmHg) 进行分层,确保组间基线平衡。

Randomization Procedure (please state who generates the random number sequence and by what method):

This study will adopt a central randomization system for stratified block randomization. Stratification was conducted based on whether diabetes was present, the triquartile of baseline LASr, and baseline systolic blood pressure (>=140/<140 mmHg) to ensure baseline balance between groups.
