Effect of Nicorandil on Cardiac Sympathetic Nerve for the Patients of Acute ST Segment Elevation Myocardial Infarction
Effects of Nicorandil on Cardiac Sympathetic Nerve Activity and Distribution in Patients With Acute Myocardial Infarction Treated With Primary Percutaneous Coronary Intervention
연구 개요
상세 설명
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 injury of cardiac sympathetic nerve, 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 especially injury of cardiac sympathetic nerve 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,moreover,it could reduces the release of norepinephrine from sympathetic endings of the heart directly.So,it could decrease the phenomenon of no-reflow/slow reflow,reperfusion-induced arrhythmia and injury of cardiac sympathetic nerve.

실험적: Nicorandil
Patients who received intracoronary and intravenous nicorandil before and after reperfusion with primary percutaneous coronary intervention
|
All patients received antiplatelet agents (aspirin, ticagrelor) and heparin.Diagnostic coronary angiography (CAG) was performed via the radial artery using the Seldinger method.The guidewire was passed into the culprit lesion.If the blood flow of culprit vessel reaches TIMI2-3 after balloon dilatation,6mg nicorandil was then administrated before stent implantation, A minimum 5-min interval occurred between the first and second doses of nicorandil to reduce adverse effects, subsequently , 6mg/h ivgtt.
up to 48h after coronary intervention
