ABSTRACT
【Subjects】 To investigate the clinical application value of myocardial contrast echocardiography (MCE) in selecting CTO-PCI patients. MethodsFrom February 2019 to March 2020, a total of 50 patients with chronic coronary artery occlusion were consecutively selected as the research subjects. MCE and two-dimensional speck-tracking echocardiography were completed before and 12 months after interventional therapy. The primary end point was major adverse cardiovascular events. Patients were divided into groups according to the preoperative myocardial perfusion level of MCE. The improvement of left ventricular function was evaluated by two-dimensional echocardiography and left ventricular global longitudinal strain. ResultsCompared with the abnormal perfusion group, the improvement of GLS in the normal perfusion group was greater (P=0.028). The wall motion score index (WMSI) of the abnormal perfusion group before PCI was higher than that of the normal perfusion group (P=0.002). WMSI in the abnormal perfusion group was higher than that in the normal perfusion group one year after PCI (P<0.001). The left ventricular GLS(P=0.008).WMSI(P=0.016) and left ventricular end-diastolic volume(P=0.032) in the normal perfusion group were improved compared with those before operation; The postoperative perfusion score of patients with abnormal perfusion was significantly improved ( P=0.032). ConclusionMCE has clinical application value in optimizing the selection of CTO-PCI patients. CTO patients with different myocardial perfusion types have different benefits after PCI.
