Evidences suggest that the presence of chronic kidney disease (CKD) is associated with cerebrovascular diseases related cognitive decline in dialysis patients. As mitochondrial dysfunction is implicated in neurodegenerative disorders, we hypothesized that changes in brain mitochondria occur due to vascular calcification induced by renal failure and the opening of the mitochondrial potassium channel using nicorandil may prevent its dysfunction. Brain tissues from rats with vascular calcification were studied...

Chronic angina pectoris is associated with considerable morbidity and mortality, especially if treated suboptimally. For many patients, aggressive pharmacologic intervention is necessary in order to alleviate anginal symptoms. The optimal treatment of stable ischemic heart disease (SIHD) should be the prevention of angina and ischemia, with the goal of maximizing both quality and quantity of life. In addition to effective risk factor modification with lifestyle changes, intensive pharmacologic secondary prevention is the therapeutic cornerstone in managing patients with SIHD...

Many scholars have studied the effect of nicorandil on perioperative myocardial protection in patients undergoing elective percutaneous coronary intervention (PCI), but results are inconsistent. Therefore, we performed this meta-analysis. Finally, 16 articles, including 1616 patients, were included into this meta-analysis. Meta-analysis results showed that: (1) Nicorandil can reduce the level of CK-MB after PCI, including at 6 hours, 12 hours, 18 hours and 24 hours. (2) Nicorandil can reduce the level of TnT after PCI, including at 6 hours, 12 hours, 18 hours and 24 hours...

INTRODUCTION: Nicorandil, a vasodilatory drug used to treat angina, was reported to protect against myocardial ischemia-reperfusion injury in various animal models. However, its cardioprotective action following cardiac arrest is unknown. We examined the cardioprotective effects of nicorandil in a porcine model of cardiac arrest and resuscitation. METHODS: Ventricular fibrillation was induced electrically for 4min in anesthetized domestic swine, followed by cardiopulmonary resuscitation...

BACKGROUND: Contrast-induced nephropathy (CIN) remains to be a potentially serious complication of radiographic procedures and is the third leading cause of the acute kidney injury (AKI) among hospitalized patients. This clinical trial was performed to assess the preventive effect of oral nicorandil on CIN in high-risk patients undergoing cardiac catheterization. METHODS: In this prospective, randomized, controlled trial, 128 patients with at least two risk factors for CIN undergoing elective percutaneous coronary intervention (PCI) were randomly assigned to either the nicorandil group or the control group...

The primary cardiotoxic action of doxorubicin when used as antitumor drug is attributed to the generation of reactive oxygen species (ROS) therefore effective cardioprotection therapies are needed. In this sense, the antianginal drug nicorandil has been shown to be effective in cardioprotection from ischemic conditions but the underlying molecular mechanism to cope with doxorubicin-induced ROS is unclear. Our in vitro study using the HL-1 cardiomyocyte cell line derived from mouse atria reveals that the endogenous nitric oxide (NO) production was stimulated by nicorandil and arrested by NO synthase inhibition...

The present study was aimed to determine the efficacy of nicorandil in treating cardiac reperfusion injury with an underlying co-morbidity of vascular calcification (VC). Adenine diet was used to induce VC in Wistar rat and the heart was isolated to induce global ischemia reperfusion (IR) by Langendorff method, with and without the nicorandil (7.5mg/kg) pre-treatment and compared with those fed on normal diet. The adenine-treated rats displayed abnormal ECG changes and altered mitochondrial integrity compared to a normal rat heart...

Fatigue is a phenomenon in which force reduction has been linked to impairment of several biochemical processes. In skeletal muscle, the ATP-sensitive potassium channels (KATP) are actively involved in myoprotection against metabolic stress. They are present in sarcolemma and mitochondria (mitoKATP channels). K(+) channel openers like nicorandil has been recognized for their ability to protect skeletal muscle from ischemia-reperfusion injury, however, the effects of nicorandil on fatigue in slow skeletal muscle fibers has not been explored, being the aim of this study...

Free intracellular calcium ([Ca(2+)]i), in addition to being an important second messenger, is a key regulator of many cellular processes including cell membrane potential, proliferation, and apoptosis. In many cases, the mobilization of [Ca(2+)]i is controlled by intracellular store activation and calcium influx. We have investigated the effect of several ion channel modulators, which have been used to treat a range of human diseases, on [Ca(2+)]i release, by ratiometric calcium imaging. We show that six such modulators [amiodarone (Ami), dofetilide, furosemide (Fur), minoxidil (Min), loxapine (Lox), and Nicorandil] initiate release of [Ca(2+)]i in prostate and breast cancer cell lines, PC3 and MCF7, respectively...

INTRODUCTION: Nicorandil has vasodilatory effects on both the epicardial coronary arteries and the coronary microvasculature, thereby increasing coronary blood flow. Intravenous administration of nicorandil can be applicable for fractional flow reserve (FFR) measurement as a hyperaemic agent and a possible alternative to adenosine. However, the effectiveness of intravenous nicorandil infusion for FFR measurement is largely unclear. METHODS AND ANALYSIS: This crossover randomised study is being performed to investigate the efficacy of intravenous administration of nicorandil for FFR measurement...
