BACKGROUND: Activation of the NLRP3 inflammasome is a primary driver of sterile inflammation in response to myocardial ischemia reperfusion. Pharmacologic inhibitors of the NLRP3 inflammasome are being developed. We proposed that OLT1177 (dapansutrile), a novel NLRP3 inflammasome inhibitor, could preserve myocardial function after ischemia reperfusion injury in the mouse. METHODS: We used an experimental murine model of myocardial ischemia reperfusion injury through transient ligation of the left coronary artery, and measured the effects of OLT1177 (6, 60 or 600 mg/kg intraperitoneal dose) on infarct size at pathology and on systolic cardiac function at echocardiography...

Statins have been suggested in previous studies to play a protective role in experimental cerebral aneurysm (CA) models; however, no evidence supports that the application of statins can protect against aneurysm rupture in humans, and the risks of lipid levels and aneurysms remain unknown. Therefore, this meta-analysis aimed to summarize and update the epidemiological evidence to systematically assess the relationships of statins therapy and hyperlipidemia with the incidence, rupture, post-repair mortality and all-cause mortality of abdominal aortic aneurysm (AAA) and CA...

BACKGROUND: Radiofrequency ablation (RFA) and antiarrhythmic drugs (AAD) are the main treatments used for atrial fibrillation (AF). In recent years, a number of articles comparing the two treatments have begun to emerge. Though, the influence of follow-up time in the meta-analysis was not considered in these articles. However, more recently, large-scale clinical trial articles have included follow-up with the patients up to five years after treatment. Therefore, the aim of this study was to assess the impact of variable follow-up times on the recurrence of AF by observing both the short-term and long-term efficacy and safety of catheter ablation and antiarrhythmic drugs for the treatment of AF...

The antihypertrophic effect of nebivolol over cardioselective beta-blockers (β-blockers) is attributed to the activation of cardiac nitric oxide signaling. However, the precise role of nebivolol on hypertrophied cardiomyocytes remains unclear. In the current study, in vitro cardiomyocyte hypertrophy model was induced with isoprenaline (10μM), angiotensin II (1μM) and phenylephrine (20μM) in neonatal cardiomyocytes isolated from 0-2 days old Sprague-Dawley rats. In addition to hypertrophic agents, cardiomyocytes were treated with nebivolol (1μM), metoprolol (10μM), N(ω)-nitro-L-arginine methyl ester(L-NAME) (100μM), KT5823 (1μM), DETA-NONOate (1-10μM) and BAY412272 (10μM)...

Atorvastatin is a lipid-regulating drug that is commonly used in clinical practice and can stabilize plaques. Increasing evidence shows that statins have anti-heart failure effects, but their specific mechanism is not clear. The purpose of this study was to investigate the cardioprotective effects of atorvastatin on heart failure in rats and its mechanism. Continuous intraperitoneal injection of 2.5 mg/kg/w doxorubicin for 6 weeks, with a cumulative dose of 15 mg/kg, was used to induce a rat model of heart failure...

To date, many questions about the extent and cause of pharmacokinetic variability of even the most widely studied and prescribed β1-adrenergic receptor blockers, such as metoprolol and bisoprolol, remain unanswered. Given that there are still no published population pharmacokinetic (PopPK) analyses of bisoprolol in routinely treated patients with acute coronary syndrome (ACS), the aim of this study was to determine its PK variability in 71 Serbian patients with ACS. PopPK analysis was carried out using a non-linear mixed effects model (NONMEM), version 7...

Hypertensive transgenic (mRen2)27 rats exhibit impaired baroreflex sensitivity (BRS) for control of heart rate (HR). Intracerebroventricular (ICV) infusion of Ang-(1-7) improves indices of vagal BRS independent of lowering mean arterial pressure (MAP), while AT1 receptor blockade normalizes MAP and indices of sympathetic tone without correcting the vagal BRS. Scavenging cellular reactive oxygen species (ROS) with tempol in brain fails to correct either hypertension or sympathovagal balance in these animals, despite reports that mitochondrial ROS contributes to Ang II-infusion hypertension...

Little is known about the dosing and tolerability of sacubitril/valsartan (LCZ696; Entresto™, Quebec, Canada) in a non-clinical trial population. This study was conducted to evaluate the use and tolerability of sacubitril/valsartan in patients followed at a multidisciplinary heart failure clinic. We performed a retrospective chart review of 126 patients with heart failure, initiated on sacubitril/valsartan, and seen at a specialty heart failure clinic between August 1, 2015 and August 1, 2017. We defined the target dose of sacubitril/valsartan as 200 mg B...

Disorders of lipid metabolism and inflammation play an important role in atherosclerosis. LongShengZhi capsule (LSZ), a Chinese herbal medicine, has been used for treatment of patients with vascular diseases for many years. Herein, we determined the effect of LSZ on the progression of established atherosclerotic lesions in apoE deficient (apoE) mice. ApoE mice were pre-fed high-fat diet (HFD) for 8 weeks to induce atherosclerosis, then started with LSZ treatment contained in HFD for 10 weeks. Although LSZ had little effect on HFD-induced hypercholesterolemia, it substantially reduced en face and sinus aortic lesions...

Our aim was to explore the efficacy of minimally invasive intervention in patients with acute cerebral infarction (ACI). Seventy patients with ACI were randomized into either an experimental group or a control group. In addition to the regular treatment, patients in the control group also received intravenous thrombolysis with urokinase, while patients in the other group underwent percutaneous transluminal cerebral angioplasty and stenting. Metrics included recanalization rate, serum cytokines, fibrinolytic markers and 36-Item Short Form Health Survey score were compared between the two groups...

Although hypothermia suppresses myocardial ischemia/reperfusion injury, whether it also protects the myocardium against cellular stresses such as chemical anoxia and calcium overload remains unknown. We examined the effect of mild hypothermia (33 °C) on myocardial injury during ischemia/reperfusion, local administration of sodium cyanide (chemical anoxia), or local administration of maitotoxin (forced Ca overload) using cardiac microdialysis applied to the feline left ventricle. Baseline myoglobin levels (in ng/ml) were 237 ± 57 and 150 ± 46 under normothermia and hypothermia, respectively (mean ± SE, n = 6 probes each)...

BACKGROUND AND OBJECTIVE: Panax Notoginseng Saponins (PNS) is a formula of Chinese Medicine commonly used for treating ischemia myocardial in China. However, its mechanism of action is yet unclear. This study investigated the effect and the mechanism of PNS on myocardial ischemia-reperfusion injury via the hypoxia-inducible factor 1α(HIF-1α)/bcl-2/adenovirus E1B19kDa-interacting protein3(BNIP3) pathway of autophagy. METHODS: We constructed a rat model of myocardial injury, and compared among4 groups (n=10, each): Sham(the sham-operated group), IR(the ischemia-reperfusion group), the PNS-low and -high dose groups were pretreated with PNS (30 and 60 mg/kg, respectively)...

This study was designed to characterize the pharmacological profile of DS37001789, which is a structurally novel piperazine derivative that acts as urotensin II (U-II) receptor antagonist. DS37001789 inhibited [I]-U-II binding to human GPR14, U-II receptor, with an IC50 value 0.9 nM. Its potency was superior to that of ACT-058362, a nonpeptide U-II receptor antagonist whose IC50 was 120 nM. Human U-II-induced vascular contraction was blocked by DS37001789. The dose-response curve of DS37001789 in rats and monkeys did not show species differences, and it shifted to the right without any effects on the maximum vascular response...

Levosimendan is an inodilator that promotes cardiac contractility primarily through calcium sensitization of cardiac troponin C and vasodilatation via opening of adenosine triphosphate-sensitive potassium (KATP) channels in vascular smooth muscle cells; the drug also exerts organ-protective effects through a similar effect on mitochondrial KATP channels. This pharmacological profile identifies levosimendan as a drug that may have applications in a wide range of critical illness situations encountered in intensive care unit medicine: hemodynamic support in cardiogenic or septic shock; weaning from mechanical ventilation or from extracorporeal membrane oxygenation; and in the context of cardiorenal syndrome...
