简要总结
To evaluate whether nicorandil as an adjunctive therapy for acute myocardial infarction (AMI) reduces reperfusion injury.
详细描述
Reperfusion injury might occur in patients with acute ST segment elevation myocardial infarction undergoing the primary percutaneous coronary intervention(P-PCI),characterized by myocardial stunning, reperfusion-induced arrhythmia, microvascular dysfunction and myocardial cellular apoptosis, etc.
Nicorandil is an antianginal agent with a dual mechanism of action: nitrate and K+ATP channel opener. The nitrate action causes vasodilation of systemic veins and epicardial coronary arteries, while the adenosine triphosphate (ATP)-sensitive potassium channel opener action causes vasodilation of peripheral and coronary resistance arterioles. Nicorandil not only decreases preload and afterload but also increases coronary blood flow.
The study will compare the effectiveness between nicorandil and placebo of preventing the reperfusion injury and left ventricle remodeling in patients with acute ST segment elevation myocardial infarction undergoing the P-PCI.It is intended that before reperfusion injury ,nicorandil which was early used by intracoronary injection could prevent and release the microcirculatory spasm, release the coronary microvascular endothelial swelling,decrease embolism of atherosclerotic debris and thrombus formation.So,it could decrease the phenomenon of no-reflow/slow reflow,reperfusion-induced arrhythmia and worsening of chest pain.

结局指标
主要结局
Primary composite endpoint (whether premature beats,atrial or ventricular tachycardia, atrial or ventricular fibrillation, and atrioventricular block appears;whether severity of chest pain is aggravated,and number of episodes chest pain)
时间窗: 24hours
The primary composite endpoint consisted of reperfusion-induced arrhythmia, worsening of chest pain, and no-reflow/slow reflow. In perioperative period,we will observe whether the reperfusion-induced arrhythmia including atrial or ventricular premature beats,atrial or ventricular tachycardia, atrial or ventricular fibrillation, and atrioventricular block appears;whether the severity of chest pain is aggravated,and the number of episodes of chest pain will be recorded for patients who complains of chest pain that lasted for at least 30 min within the 24 h following onset of MI;Whether the phenomenon of no-reflow/slow reflow appears.No-reflow and slow flow are diagnosed when the thrombolysis in myocardial infarction(TIMI) flow grade is 2 or lower,despite successful PCI such as balloon angioplasty or stent insertion.
次要结局
- the combined outcome of TIMI frame count (cTFC) of CAG and ST resolution (STR) of ECG(24hours)
