Clinical Study of Cardiomyopeptidin on Postoperative Ischemia-reperfusion Injury in Patients With Primary PCI

May 19, 2019 updated by: Dalian Zhen-Ao Bio-Tech Co., Ltd.

A Randomized, Single-blind, Controlled Clinical Trial of Cardiomyopeptidin Intervention in Patients With Acute ST-segment Elevation Myocardial Infarction Undergoing Direct PCI After Ischemia-reperfusion Injury

In this study, advanced techniques of myocardial nuclear magnetic perfusion scanning were used to quantitatively assess infarct size after acute myocardial infarction, saved viable myocardium, and microcirculatory obstruction area. Objectively and quantitatively evaluate early use of cardiomyopeptidin for direct PCI of ST-segment elevation myocardial infarction. After the improvement of microcirculation and increase the intervention effect of viable myocardium.

Study Overview

Detailed Description

This is a prospective, randomized, controlled, single-blind, single-center clinical trial. Patients with ST-segment elevation myocardial infarction (STEMI) who were admitted in the People's Liberation Army General Hospital were equally randomized to receive either cardiomyopeptidin or placebo, and patients in cardiomyopeptidin group are given the injection of cardiomyopeptidinl before primary percutaneous coronary intervention (PCI) and intravenous infusion of cardiomyopeptidin was performed 3 days after primary PCI. Myocardial perfusion flow grade was evaluated by the result of primary PCI. Myocardial infarct size, microvascular obstruction and salvage myocardium were evaluated by enhanced cardiac magnetic resonance (CMR). Major adverse cardiovascular events (nonfatal myocardial infarction, all-cause death, hospitalization for acute heart failure, and revascularization for angina) were observed during the 6-month follow-up. CMR is performed to evaluate the effect of cardiomyopeptidin before primary PCI on myocardial salvage and microcirculation perfusion in patients with STEMI.
