During cardiac failure, cardiomyocytes have difficulty in using the substrates to produce energy. L-carnitine is a necessary nutrient for the transport of fatty acids that are required for generating energy. Coronary artery graft surgery reduces the plasma levels of L-carnitine and increases the oxidative stress. This study demonstrates the effect of L-carnitine supplementation on the reverse remodeling of patients undergoing coronary artery bypass graft. Patients with ischemic heart failure who underwent coronary graft surgery were randomized to group A - supplemented with L-carnitine or group B controls...

Mitochondrial homeostasis is critical for keeping functional heart in response to metabolic or environmental stresses. Mitochondrial fission and fusion (mitochondrial dynamics) play essential roles in maintaining mitochondrial homeostasis, defects in mitochondrial dynamics lead to cardiac diseases such as ischemia-reperfusion injury (IRI), heart failure and diabetic cardiomyopathy. Mitochondrial dynamics is determined by mitochondrial fission and fusion proteins, including OPA1, mitofusins and Drp1. These proteins are tightly regulated by a series of signaling pathways through different aspects such as transcription, post translation modifications (PTMs) and proteasome-dependent protein degradation...

PURPOSE: Pulmonary arterial hypertension (PAH) is a fatal disease which is characterized by an increase in pulmonary arterial pressure leading to increases in right ventricular afterload. Human umbilical cord blood derived-mesenchymal stem cells (hUCB-MSCs) administered via the jugular vein have been previously shown to improve PAH by reversal treatment. However, the effect of low dosage and transfusion timing of hUCB-MSCs on PAH has not yet been clearly established. Obviously, low dosage treatment can lead to a reduction in costs...

Aims: Short-term studies have reported left ventricular (LV) dilatation following surgical creation of arteriovenous fistulas (AVF) or arteriovenous grafts (AVGs), but chronic cardiac structural and functional changes have not been examined or related to clinical outcomes following AVF/AVG. We sought to characterize the long-term changes in cardiac structure and function in patients undergoing shunt creation for haemodialysis. Methods and results: A retrospective analysis was performed of patients undergoing echocardiography before and after surgical AVF/AVG creation for the initiation of haemodialysis...

Several studies have linked impaired glucose uptake and insulin resistance (IR) to functional impairment of the heart. Recently, endocannabinoids have been implicated in cardiovascular disease. However, the mechanisms involving endocannabinoid signaling, glucose uptake and IR in cardiomyocytes are understudied. Here, we report the endocannabinoid 2-Arachidonoylglycerol (2-AG) via stimulation of cannabinoid type-1 (CB1) receptor and Ca2+/Calmodulin-dependent protein kinase β (CaMKKβ) activates AMPK leading to increased glucose uptake...

Cardiac myosin binding protein C (cMyBP-C) is a cardiac structural and regulatory protein; mutations of cMyBP-C are frequently associated with hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM). Cardiac special transcription factors may regulate the expression of cMyBP-C. However, the role of cMyBP-C in congenital heart diseases (CHD) remains poorly understood. In the current study, western blotting and the MRM approach showed that cMyBP-C expression was significantly reduced in fetuses with CHD compared to those without...

AIMS: Platelets retain cytoplasmic messenger RNA and are capable of protein biosynthesis. Several diseases are known to impact the platelet transcriptome but the effect of non-valvular atrial fibrillation (NVAF) on platelet RNA transcript is essentially unknown. The aim of this study was to evaluate the impact of NVAF on platelet RNA transcript by measuring platelet genes expression in consecutive NVAF patients before and 3-4 months after pulmonary vein isolation (PVI) and compared to normal sinus rhythm controls (NSR)...

This study sought to evaluate the potential of circulating long non-coding RNAs (lncRNAs) as biomarkers for heart failure (HF). We measured the circulating levels of 13 individual lncRNAs which are known to be relevant to cardiovascular disease in the plasma samples from 72 HF patients and 60 non-HF control participants using real-time reverse transcription-polymerase chain reaction (real-time RT-PCR) methods. We found that out of the 13 lncRNAs tested, non-coding repressor of NFAT (NRON) and myosin heavy-chain-associated RNA transcripts (MHRT) had significantly higher plasma levels in HF than in non-HF subjects: 3...

BACKGROUND: Valvular interstitial cells (VICs) in the healthy aortic valve leaflet exhibit a quiescent phenotype, with <5% of VICs exhibiting an activated phenotype. Yet, in vitro culture of VICs on tissue culture polystyrene surfaces in standard growth medium results in rapid transformation to an activated phenotype in >90% of cells. The inability to preserve a healthy VIC phenotype during in vitro studies has hampered the elucidation of mechanisms involved in calcific aortic valve disease...

Ang II has been involved in the pathogenesis of cardiovascular diseases, and matrix metalloproteinase-9 (MMP-9) induced migration of human aortic smooth muscle cells (HASMCs) is the most common and basic pathological feature. Carbon monoxide (CO), a byproduct of heme breakdown by heme oxygenase, exerts anti-inflammatory effects in various tissues and organ systems. In the present study, we aimed to investigate the effects and underlying mechanisms of carbon monoxide releasing molecule-2 (CORM-2) on Ang II-induced MMP-9 expression and cell migration of HASMCs...

Diagnosis of dilation (D) cardiomyopathy (CMP) requires exclusion not only of inflammatory and genetically determined forms but also of some rare diseases. This 51 year old patient with history of moderate arterial hypertension approached a cardiologist because of new onset atrial fibrillation and dyspnea. Echocardiography detected dilation of all cardiac chambers with relatively preserved ejection fraction, causing suspicion of DCMP. Among conditions excluded were coronary atherosclerosis, congenital heart defect with left to right shunt, primary pulmonary hypertension, pulmonary embolism, hypertensive heart, tachycardia induced CMP, arrhythmogenic right ventricular dysplasia, noncompaction myocardium...

BACKGROUND AND PURPOSE: There is increasing interest in extracellular RNAs (ex-RNAs), with numerous reports of associations between selected microRNAs (miRNAs) and a variety of cardiovascular disease phenotypes. Previous studies of ex-RNAs in relation to risk for cardiovascular disease have investigated small numbers of patients and assayed only candidate miRNAs. No human studies have investigated links between novel ex-RNAs and stroke. METHODS: We conducted unbiased next-generation sequencing using plasma from 40 participants of the FHS (Framingham Heart Study; Offspring Cohort Exam 8) followed by high-throughput polymerase chain reaction of 471 ex-RNAs...

Heart failure (HF) is a common cause of death and disability and a major economic burden in industrialized nations. Heart disease remains the leading cause of death in North America, with ischemic and hypertensive heart disease as the leading cause of HF. Various basic and clinical studies have established the role of an activated renin-angiotensin (Ang) system and Ang II generation in the progression of HF. Inhibition of an activated renin-Ang system using Ang-converting enzyme inhibitors, Ang II type 1 receptor blockers, and mineralocorticoid receptors antagonists have shown clinical benefits in patients with HF, although, largely limited to HF with reduced ejection fraction (HF-rEF)...
