Clinical and Electrocardiographic Characteristics in NSTEMI Patients With Acute Total Occlusion of Culprit Left Circumflex Artery
Background
Complete blockage of the culprit coronary artery is associated with 30% of NSTEMI (non-ST-segment elevation myocardial infarction) patients. The culprit vessel in the left circumflex artery (LCX) is more prevalent in this subset of individuals. These people's clinical features and ischemia alterations on electrocardiography (ECG) are unknown. The goals of this study were to examine clinical features and identify predicted ECG abnormalities in NSTEMI patients with complete blockage of the culprit LCX.
Methods
This study enrolled 5215 consecutive NSTEMI patients' data. A total of 180 people were diagnosed with acute total occlusion of the culprit artery (ATOCA). Based on the culprit vessel, the patients were classified into three groups:ATOCA in the LAD (n = 46), ATOCA in the RCA (n = 38) and ATOCA in the LCX (n = 96). Furthermore, basic clinical data, ECG alterations, and the occurrence of major adverse cardiac events (MACEs) were gathered and examined.
Results
In this single-center investigation, we discovered that ATOCA was more prevalent in patients with NSTEMI in the LCX group. Patients with culprit LCX were more prone to having multivessel coronary disease (p = 0.015), poorer LVEF (p = 0.040), and a lower revascularization success rate (p = 0.019) during hospitalization, although there were no significant differences in MACEs in short and long follow-up. STV5 + STV6 ≥ 2.5 mm (OR = 2.595, 95% CI: 1.297 ~ 5.192) and T-wave imbalance (defined as an upright T-wave in V1 with an amplitude larger than V6 (T1–T6 ≥ 1 mm) recorded from the P-R interval)(OR = 3.871, 95% CI: 1.820 ~ 8.231) were shown to be independent predictors of NSTEMI patients with acute complete blockage of the culprit LCX in multivariate regression analysis.
Conclusion
The LCX is the most prevalent culprit vessel with acute complete occlusion in NSTEMI patients, yet it has little effect on clinical outcomes. This subset of patients may be predicted by STV5 + STV6 ≥ 2.5 mm and T-wave imbalance.
期刊介绍：
The ANNALS OF NONINVASIVE ELECTROCARDIOLOGY (A.N.E) is an online only journal that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients.
ANE is the first journal in an evolving subspecialty that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients. The publication includes topics related to 12-lead, exercise and high-resolution electrocardiography, arrhythmias, ischemia, repolarization phenomena, heart rate variability, circadian rhythms, bioengineering technology, signal-averaged ECGs, T-wave alternans and automatic external defibrillation.
ANE publishes peer-reviewed articles of interest to clinicians and researchers in the field of noninvasive electrocardiology. Original research, clinical studies, state-of-the-art reviews, case reports, technical notes, and letters to the editors will be published to meet future demands in this field.
