Abstract：
Chronic total coronary occlusions (CTO) occur in up to 50 % of patients with coronary artery disease by angiography. In CTO-patients, clinically significant arrhythmia is potentially important and insufficiently investigated. Therefore, the purpose of the CTO-ARRHYTHMIA study was to investigate the incidence of loop recorder detected clinically significant arrhythmias and the effect on arrhythmias of revascularization by CTO-PCI. The study is an independent sub-study of the NOrdic-Baltic Randomized Registry Study for Evaluation of PCI in Chronic Total Coronary Occlusion (NOBLE-CTO); ClinicalTrials.gov Identifier NCT03392415. NOBLE-CTO prospectively collects procedural data, quality of life measures, echocardiographic and cardiac MRI findings before and after treatment as well as clinical outcomes in all CTO patients that may be treated by PCI.
摘要：
通过血管造影，多达50％的冠状动脉疾病患者发生慢性完全冠状动脉闭塞（CTO）。在CTO患者中，临床上有意义的心律失常是潜在的重要因素,并且研究不充分.因此,CTO-ARRHYTHMIA研究的目的是调查环路记录仪检测到的临床显著心律失常的发生率以及CTO-PCI对血运重建的心律失常的影响.该研究是NOrdic-Baltic随机注册研究的独立子研究，用于评估慢性完全冠状动脉闭塞症的PCI（NOBLE-CTO）；ClinicalTrials.gov标识符NCT03392415。NOBLE-CTO前瞻性地收集程序数据，生活质量衡量标准，所有可能接受PCI治疗的CTO患者治疗前后的超声心动图和心脏MRI表现以及临床结果。
