clinical efficacy of extracorporeal cardiac shock wave therapy in patients with ischemia-reperfusion injury

Conditions: Myocardial Reperfusion Injury; Treatment Outcome; Prognosis; ST Elevation Myocardial Infarction

Summary: this trial was a prospective, open-label, single-center, randomized trial, to observe the clinical efficacy of extracorporeal cardiac shock wave in the treatment of patients with myocardial ischemia-reperfusion injury and the difference in the level of endothelial progenitor cell-derived mir-140-3p in patients with myocardial ischemia-reperfusion injury treated with extracorporeal cardiac shock wave and control group and its relationship with clinical efficacy and prognosis. in order to provide a new therapy for patients with myocardial ischemia-reperfusion injury.

Eligibility criteria:
inclusion criteria: age ≥18 years the patient was diagnosed with acute st-segment elevation myocardial infarction for the first time, and coronary angiography showed moderate to severe coronary artery stenosis. pci was performed within 12 hours of the onset of the disease according to the current guidelines, and postoperative hemodynamic stability was achieved ccs angina pectoris grade ⅱ or above, nyha cardiac function grade i-ⅲ imaging examination \[stress echocardiography and/or stress myocardial perfusion imaging\] suggested objective evidence of reversible myocardial ischemia voluntary participation, able to cooperate with treatment and follow-up, signed informed consent. exclusion criteria: severe unprotected left main stem lesions left ventricular systolic function was impaired with hemodynamic instability chronic obstructive pulmonary disease, pulmonary maculopathy, post-pseudobulbar placement or other causes of poor sonographic window combined with chest malignant tumor pregnancy the skin of the treatment area is broken or infected nyha cardiac function grade ⅳ acute myocarditis, pericarditis, moderate or large amount of pericardial effusion, infective endocarditis, deep vein thrombosis, intracardiac thrombosis; severe aortic stenosis, aortic aneurysm, thoracic aortic dissection, thoracic aortic aneurysm, after heart transplantation, metal heart valve replacement, pulmonary embolism patients undergoing thrombolysis and surgical bypass patients with a history of mental illness, poor compliance and inability to cooperate.
