PURPOSE: Transplantation of mesenchymal stem cells (MSCs) is a promising therapeutic option for patients with acute myocardial infarction. METHODS: We show here that the ectopic overexpression of endothelial nitric oxide synthases (eNOS), an endothelial form of NOS, could enhance the ability of MSCs in treating ischemic heart damage after the occlusion of the coronary artery. RESULTS: Adenoviral delivery of human eNOS gene into mouse bone marrow-derived MSCs (BM-MSCs) conferred resistance to oxygen glucose deprivation (OGD)-induced cell death in vitro, and elevated the bioavailability of nitric oxide when injected into the myocardium in vivo...

LCZ696, a first-in-class angiotensin receptor neprilysin inhibitor (ARNI), is comprised of the angiotensin receptor blocker valsartan and the neprilysin inhibitor pro-drug sacubitril (AHU377). After oral administration, AHU377 is rapidly metabolized to the active neprilysin inhibitor LBQ657. LCZ696 exerts its effects of diuresis, natriuresis, vasodilation and aldosterone secretion inhibition through simultaneous renin-angiotensin-aldosterone system (RAAS) blockade and natriuretic peptides system (NPS) enhancement...

RATIONALE: Pulmonary hypertension (PH) represents a serious health complication accompanied with hypoxic conditions, elevated levels of asymmetric dimethylarginine (ADMA), and overall dysfunction of pulmonary vascular endothelium. Since the prevention strategies for treatment of PH remain largely unknown, our study aimed to explore the effect of nitro-oleic acid (OA-NO2), an exemplary nitro-fatty acid (NO2-FA), in human pulmonary artery endothelial cells (HPAEC) under the influence of hypoxia or ADMA...

PURPOSE: Endoplasmic reticulum (ER) stress contributes to pulmonary artery hypertension (PAH). However, the exact roles of ER stress in right ventricular (RV) dysfunction, which is strongly associated with PAH, are largely unknown. Here, we aimed to explore how ER stress affects RV function in a rat PAH model and evaluated the effects of an ER stress inhibitor on RV dysfunction. METHODS: We examined expression changes of an ER marker: chaperone glucose-regulated protein 78 (GRP78), three ER stress sensor proteins: activating transcription factor 6 (ATF6), inositol-requiring enzyme 1 (IRE1), and protein kinase RNA-like endoplasmic reticulum kinase (PERK), and a key ER stress-induced apoptosis indicator: CCAAT/enhancer-binding protein homologous protein (CHOP), with inflammation indicators: interleukin 6 (IL-6), tumor necrosis factor-α (TNF-α), and matrix metalloproteinases (MMPs) in RV at 3, 7, 14 and 28 days following a single dose of monocrotaline (MCT) injection, with or without a preventive treatment [4-phenylbutyric acid (PBA)]...

PURPOSE: Current human umbilical cord blood stem cell therapy faces the great challenges, because the stem cells are scarce and cannot survive for a long time. Here we describe how hetrombopag, an orally-active TPO receptor agonists, enhanced ex vivo expansion of human UCB stem cells, and protected cardiac myocytes from the damage caused by oxidative stress. METHODS: Ex vivo expansion of stem cells were performed in serum-free medium supplemented with rhSCF and rhFL plus hetrombopag for 7 days...

BACKGROUND: Ticagrelor inhibits the equilibrative-nucleoside-transporter-1 and thereby, adenosine cell re-uptake. Ticagrelor limits infarct size (IS) in non-diabetic rats and the effect is adenosine-dependent. Statins, via ecto-5'-nucleotidase activation, also increase adenosine levels and limit IS. HYPOTHESIS: Ticagrelor and rosuvastatin have additive effects on myocardial adenosine levels, and therefore, on IS and post-reperfusion activation of the NLRP3-inflammasome...

BACKGROUND: Diuretics are the mainstay of treatment for congestion but concerns exist that they adversely affect prognosis. We explored whether the relationship between loop diuretic use and outcome is explained by the underlying severity of congestion amongst patients referred with suspected heart failure. METHOD AND RESULTS: Of 1190 patients, 712 had a left ventricular ejection fraction (LVEF) ≤50 %, 267 had LVEF >50 % with raised plasma NTproBNP (>400 ng/L) and 211 had LVEF >50 % with NTproBNP ≤400 ng/L; respectively, 72 %, 68 % and 37 % of these groups were treated with loop diuretics including 28 %, 29 % and 10 % in doses ≥80 mg furosemide equivalent/day...

Most, if not all, cells of the cardiovascular system secrete small, lipid bilayer vesicles called exosomes. Despite technical challenges in their purification and analysis, exosomes from various sources have been shown to be powerfully cardioprotective. Indeed, it is possible that much of the so-called "paracrine" benefit in cardiovascular function obtained by stem cell therapy can be replicated by the injection of exosomes produced by stem cells. However, exosomes purified from plasma appear to be just as capable of activating cardioprotective pathways...

BACKGROUND: Patients with coronary artery disease who undergo stent implantation and have concomitant indication for long-term oral anticoagulation represent a considerable proportion of the overall population. To date there is still no consensus about the optimal antithrombotic strategy to choose in this kind of patients, due to the difficult balance between an increased risk of bleeding and thromboembolic complications. Therefore, the aim of this study was to perform a meta-analysis to evaluate the risk and benefits of triple antithrombotic therapy versus dual antithrombotic therapy in patients undergoing coronary stent implantation, requiring long-term oral anticoagulation...

INTRODUCTION: Mechanical and morphological ischemia and reperfusion (I/R) injury is reduced in septic hearts. The mechanism behind this "cardioprotection" is less well understood. As adenosine receptors play a major role for cardioprotection in non-septic hearts, we investigated the influence of adenosine receptors in a model of I/R in septic hearts. METHODS: SHAM operation or cecal ligation and puncture (CLP) was performed in adult male Wistar rats (n = 60)...

Adiponectin is the most abundant adipokine and exhibits anti-inflammatory, antiatherogenic and antidiabetic properties. Unlike other adipokines, it inversely correlates with body weight and obesity-linked cardiovascular complications. Diastolic dysfunction is the main mechanism responsible for approximately half of all heart failure cases, the so-called heart failure with preserved ejection fraction (HFpEF), but therapeutic strategies specifically directed towards these patients are still lacking. In the last years, a link between adiponectin and diastolic dysfunction has been suggested...

PURPOSE: Dysfunctional mitochondria are considered to be the major source of intracellular reactive oxygen species and play a central role in the pathophysiology of myocardial ischemia/reperfusion. This study sought to determine effects of mitochondria-targeted cytoprotective peptide SBT-20 on myocardial infarct size in two different models of ischemia/reperfusion. METHODS: For in vivo studies, anesthetized Sprague Dawley rats were subjected to 30 min of coronary artery occlusion followed by 3 h of reperfusion...

The size of the myocardial infarction remains an important therapeutic target, because heart attack size correlates with mortality and heart failure. In this era, myocardial infarct size is reduced primarily by timely reperfusion of the infarct related coronary artery. Whereas numerous pre-clinical studies have shown that certain pharmacologic agents and therapeutic maneuvers reduce myocardial infarction size greater than reperfusion alone, very few of these therapies have translated to successful clinical trials or standard clinical use...

PURPOSE: After injection in the bloodstream, a lipid nanoparticle (LDE) resembling low-density lipoprotein (LDL) concentrates in atherosclerotic lesions of cholesterol-fed rabbits. Here, rabbits with atherosclerosis were treated with carmustine, an antiproliferative agent used in cancer chemotherapy, associated to LDE to investigate the effects on the lesions. METHODS: Twenty-seven male New Zealand rabbits were fed a 1 % cholesterol diet for 8 weeks. After 4 weeks nine animals were treated with intravenous saline solution, nine with intravenous LDE alone, and nine with intravenous LDE-carmustine (4 mg/kg, weekly for 4 weeks)...

PURPOSE: The latest resuscitation guidelines recommend the use of amiodarone in adult patients with out-of-hospital cardiac arrest (OHCA) and refractory ventricular fibrillation (VF) to improve the rates of return of spontaneous circulation. However, there is limited evidence to suggest that amiodarone is superior to lidocaine with respect to survival at discharge. The purpose of the present study was to evaluate the hypothesis that amiodarone is superior to lidocaine with regard to the rate of survival to hospital discharge for OHCA patients with VF/pulseless VT (pVT) on hospital arrival...

PURPOSE: Even with statins and other lipid-lowering therapy (LLT), many patients with heterozygous familial hypercholesterolemia (heFH) continue to have elevated low-density lipoprotein cholesterol (LDL-C) levels. ODYSSEY HIGH FH (NCT01617655) assessed the efficacy and safety of alirocumab, a proprotein convertase subtilisin/kexin type 9 monoclonal antibody, versus placebo in patients with heFH and LDL-C ≥ 160 mg/dl despite maximally tolerated statin ± other LLT. METHODS: Patients were randomized to subcutaneous alirocumab 150 mg or placebo every 2 weeks (Q2W) for 78 weeks...

PURPOSE: Chronically elevated catecholamine levels activate cardiac β-adrenergic receptors, which play a vital role in the pathogenesis of heart failure. Evidence suggests that vasostatin-1 (VS-1) exerts anti-adrenergic effects on isolated and perfused hearts in vitro. Whether VS-1 ameliorates hypertrophy/remodeling by inducing the chronic activation of β-adrenergic receptors is unknown. The present study aims to test the efficacy of using VS-1 to treat the advanced hypertrophy/remodeling that result from chronic β-adrenergic receptor activation and to determine the cellular and molecular mechanisms that underlie this response...
