研究目的:

本研究旨在明确在CCTA临界病变(50-90%)的稳定型冠心病患者中,MCG的使用是否可以优化临床诊疗路径,减少不必要的ICA;明确在CCTA临界病变(50-90%)的稳定型冠心病患者中,MCG的使用是否可改善患者生活质量,减少医疗支出。  

Objectives of Study:

This study aims to determine whether the use of MCG can optimize the clinical management pathway and reduce unnecessary ICA in stable CAD patients with borderline CCTA lesions (50-90%); and to determine whether the use of MCG can improve patient quality of life and reduce healthcare costs in this same patient population.

组别:

常规诊疗组

样本量:

656

Group:

Conventional Management Group

Sample size:

干预措施:

根据狭窄程度、验前概率及功能学检查结果推荐治疗策略:对于50-70%狭窄程度患者,若验前概率小于15%,必须结合一种或一种以上功能学检查结果(运动负荷心电图、负荷超声、SPECT及负荷CMR等),由临床医生综合判断进行治疗策略推荐;若验前概率大于15%,建议结合功能学检查结果推荐治疗策略;对于CCTA70-90%的患者,可由临床医生直接推荐ICA/最佳药物治疗

干预措施代码:

Intervention:

Treatment strategies were recommended based on stenosis severity, pre-test probability, and functional test results: For patients with 50-70% stenosis, if the pre-test probability was <15%, treatment recommendations had to be made by clinicians integrating one or more functional test results (e.g., exercise ECG, stress echocardiography, SPECT, stress CMR); if the pre-test probability was ≥15%, it was advised to recommend treatment strategies considering functional test results. For patients with CCTA-indicated 70-90% stenosis, clinicians could directly recommend ICA or optimal medical therapy.

随机方法(请说明由何人用什么方法产生随机序列):

由不参与临床试验的统计师,在计算机上通过SAS统计软件采用分层区组随机的方法生成随机号和分组信息,产生随机的种子数以及随机结果作为盲底保存。各中心作为分层,基于中心随机化网络服务系统,按照1:1的比例分层随机化分组。

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

A statistician not involved in the trial generated the randomization sequence and group assignments via SAS statistical software using a stratified block design. The random seed and allocation results were preserved as the allocation concealment. Stratified by study center and using a web-based central randomization system, participants were randomized in a 1:1 ratio.
