Study leader's address:

This retrospective study evaluates the diagnostic efficacy of speckle tracking echocardiography (STE) in identifying the culprit vessel (CV) among 142 patients with non-ST-segment elevation acute coronary syndromes (NSTEMI), comparing its performance with electrocardiogram (ECG) and transthoracic echocardiography (TTE). This study addresses a critical gap in non-invasive CV identification, offering clinicians a practical tool for pre-angiography decision-making. The results align with emerging evidence on STE’s role in ischemic heart disease while highlighting its advantages over conventional methods. We believe this work will interest readers in cardiology, echocardiography, and acute coronary syndrome management.

研究目的:

本研究试图证实该技术在NSTEMI患者定位犯罪血管诊断方面的价值,可为治疗方案的选择提供更加可靠的参考,目的为利用无创技术达到术前预测犯罪血管,并帮助临床医生进行鉴别诊断。  

Objectives of Study:

This study aims to validate the value of STE in identifying the culprit vessel in NSTEMI patients, which may provide a more reliable reference for treatment strategy selection. The objective is to achieve non-invasive preoperative prediction of the culprit vessel and assist clinicians in differential diagnosis.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

非ST段抬高型心肌梗死诊断参照中国心肌梗死诊疗专家共识: (1)入院时12导联心电图示新发或一过性两个及以上连续导联ST压低≥0.1mV或T波倒置≥0.2mV; (2)患者具有缺血性心脏病典型临床症状; (3)肌钙蛋白等生物学标志物增高或增高后降低,且至少一个值高于参考上限的第 99个百分位数; (4)GRACE风险评分为中低危组(小于140分)。

Inclusion criteria

The diagnosis of non-ST-segment elevation myocardial infarction (NSTEMI) is based on the Chinese Expert Consensus on the Diagnosis and Treatment of Myocardial Infarction: (1) A 12-lead electrocardiogram (ECG) at admission shows new or transient ST-segment depression >=0.1 mV or T-wave inversion >=0.2 mV in two or more contiguous leads; (2) The patient exhibits typical clinical symptoms of ischemic heart disease; (3) Elevated or dynamically changing biomarkers such as cardiac troponin, with at least one value above the 99th percentile upper reference limit; (4) A GRACE risk score indicating intermediate to low risk (less than 140 points).

排除标准:

(1)严重心脏瓣膜病; (2)房颤(心率快于100次/分); (3)心包炎及大量心包积液; (4)入院和/或住院期间心电图上出现完全束支传导阻滞; (5)超声心动图图像质量欠佳,无法进行有效分析。

Exclusion criteria:

(1) Severe valvular heart disease; (2) Atrial fibrillation (with heart rate exceeding 100 beats per minute); (3) Pericarditis and massive pericardial effusion; (4) Complete bundle branch block observed on electrocardiogram (ECG) at admission and/or during hospitalization; (5) Poor-quality echocardiographic images that preclude effective analysis.
