雷诺嗪是FDA批准的抗心绞痛药物。实验和临床研究表明雷诺嗪在心室和心房均有抗心律失常作用。在心室中,雷诺嗪可以抑制与急性冠状动脉综合征、长QT、心力衰竭、缺血和再灌注相关的心律失常。在心房,雷诺嗪有效抑制房性快速性心律失常和房颤(AF)。最近的研究表明,该药物作为口袋里的药丸使用时,即使在心脏结构受损的患者中,也可以有效和安全地抑制AF,这还有待进一步研究。雷诺嗪抗心律失常作用的主要机制被认为主要是通过抑制心室中的晚期INa,以及通过使用依赖性抑制心房中的峰值INa和IKr。雷诺嗪的短期和长期安全性已在临床中得到证实,即使在结构性心脏病患者中也是如此。本文综述了雷诺嗪的电生理作用和临床前和临床研究中的抗癫痫特性。
Ranolazine is an FDA-approved anti-anginal agent. Experimental and clinical studies have shown that ranolazine has anti-arrhythmic effects in both ventricles and atria. In the ventricles, ranolazine can suppress arrhythmias associated with acute coronary syndrome, long QT, heart failure, ischemia, and reperfusion. In atria, ranolazine effectively suppresses atrial tachyarrhythmias and fibrillation (AF). Recent studies have shown that the drug may be effective and safe in suppressing AF when used as a pill-in-the pocket approach, even in patients with structurally compromised hearts, warranting further study. The principal mechanism underlying ranolazine’s antiarrhythmic actions is thought to be primarily via inhibition of late INa in the ventricles, and via use-dependent inhibition of peak INa and IKr in the atria. Short and long term safety of ranolazine has been demonstrated in the clinic, even in patients with structural heart disease. This review summarizes the available data regarding the electrophysiological actions, and anti-arrhythmic properties of ranolazine in preclinical and clinical studies.
