Cardiomyopathy and associated heart failure continues to be one of the most severe complications that threaten a large population. Curcumin, one of the three curcuminoids of the spice turmeric, is very well known for a multitude of health benefits and functions. Norepinephrine (NE), a catecholamine and also a stress hormone may cause the cardiomyocytes to develop increased sensitivity to death with its increasing concentrations. In this study, we investigated the cardioprotective effect of curcumin in NE-induced cardiac apoptosis using several fluorescent and nonfluorescent microscopic techniques like DAPI, PI, Giemsa, PicroSirius and TUNEL...

We report the case of a 17-year-old female patient with known hypertrophic cardiomyopathy and a Wolff-Parkinson-White syndrome. She came to our department for further evaluation of a new diagnosed dilated cardiomyopathy characterized by an enlargement of the left ventricle and a fall in ejection fraction. Clinically, she complained about atypical chest pain, arrhythmic episodes with presyncopal events, and dyspnea (NYHA III) during the last 6 months. Non-invasive and invasive examinations including magnetic resonance imaging, electrophysiological examinations, and angiography did not lead to a conclusive diagnosis...

AIMS: Iron deficiency (ID) is highly prevalent in patients with heart failure (HF) worldwide regardless of haemoglobin levels. Results from therapeutic trials of intermittently dosed intravenous (i.v.) iron are promising in the ambulatory Caucasian population with HF with reduced left ventricular ejection fraction, although evidence is scarce in Asia. The Pilot Randomized Controlled Trial to Assess the Role of Intravenous Ferric Carboxymaltose in Asian Patients with Heart Failure aims to assess the effect of single-dose i...

We report the case of a 69-year-old man with dilated cardiomyopathy treated with a permanent catheter drainage system for diuretic resistant cardiac ascites. At 1 year follow-up, the patient had no heart failure related hospitalisations, displayed improved quality of life measures and had incurred no complications related to the catheter. Permanent tunnelled catheters are widely used to treat malignant ascites but may also be considered for palliation of cardiac ascites.

AIMS: Peripartum cardiomyopathy (PPCM) is a major cause of acute heart failure in the peripartum period and considered potentially life threatening. While many aspects of its clinical profiles have been frequently reported, functional analysis, in particular of the right ventricle, and tissue characterization by cardiovascular magnetic resonance (CMR) imaging have been only sporadically described. The aim of the present study was to analyse pathological alterations and their prognostic relevance found in CMR imaging of patients newly diagnosed with PPCM...

Heart failure is a major public issue, and dilated cardiomyopathy (DCM) is one of the common etiologies of heart failure. DCM is generally progressive, and some patients with DCM need heart transplant despite optimal medical and mechanical therapy. Current guidelines recommend inhibitors of renin-angiotensin-aldosterone system, namely angiotensin-converting-enzyme (ACE) inhibitor, angiotensin receptor blocker (ARB), and mineralocorticoid receptor antagonist as well as beta-blockers for the medical treatment of heart failure with reduced ejection fraction, including DCM...

BACKGROUND: Beta-blockers (BBs) are the mainstay prognostic medication for all stages of chronic heart failure (CHF). There are many classes of BBs, each of which has varying levels of evidence to support its efficacy in CHF. However, most CHF patients have one or more comorbid conditions such as diabetes, renal impairment, and/or atrial fibrillation. Patient enrollment to randomized controlled trials (RCTs) often excludes those with certain comorbidities, particularly if the symptoms are severe...

BACKGROUND: Myocardial noncompaction of the left ventricle is a congenital cardiomyopathy characterised by left ventricular hypertrabeculation and prominent intertrabecular recesses. The incidence ranges from 0.15% to 2.2%. Clinical manifestations include heart failure, arrhythmias, and stroke. Prognosis is fatal in most cases. Heart transplantation is a therapeutic option for this cardiomyopathy, and few had been made worldwide. CLINICAL CASE: The case is presented of a 20 year-old male with noncompacted myocardium of the left ventricle, who had clinical signs of heart failure...

The prevalence of cardiovascular disease, including cardiac arrhythmia, coronary artery disease, cardiomyopathy, and valvular heart disease, is higher in hemodialysis (HD) patients than in the US resident population. Cardiovascular disease is the leading cause of death in HD patients and the principal discharge diagnosis accompanying 1 in 4 hospital admissions. Furthermore, the rate of hospital admissions for either heart failure or fluid overload is persistently high despite widespread use of β-blockers and renin-angiotensin system inhibitors and attempts to manage fluid overload with ultrafiltration...

Improved quality of life for patients after left ventricular assist device (LVAD) implantation can be greatly limited by peripheral vascular disease even if heart failure symptoms are resolved by LVAD support. We present a case of concomitant thoracic aortobifemoral bypass and LVAD implantation in a patient with ischemic cardiomyopathy, severe peripheral vascular disease, and multiple previous failed revascularization attempts. In this patient, we used the LVAD outflow to provide the inflow to the femoral artery bypass graft...

A functional crosstalk between epigenetic regulators and metabolic control could provide a mechanism to adapt cellular responses to environmental cues. We report that the well-known nuclear MYST family acetyl transferase MOF and a subset of its non-specific lethal complex partners reside in mitochondria. MOF regulates oxidative phosphorylation by controlling expression of respiratory genes from both nuclear and mtDNA in aerobically respiring cells. MOF binds mtDNA, and this binding is dependent on KANSL3. The mitochondrial pool of MOF, but not a catalytically deficient mutant, rescues respiratory and mtDNA transcriptional defects triggered by the absence of MOF...

BACKGROUND: Correlation of increased copeptin levels with various cardiovascular diseases has been described. The clinical use of copeptin levels in patients with hypertrophic cardiomyopathy (HCM) has not been investigated before. HYPOTHESIS: In this study, we aimed to investigate the prognostic value of copeptin levels in patients with hypertrophic cardiomyopathy (HCM). METHODS: HCM was defined as presence of left ventricular wall thickness ≥15 mm in a subject without any concomitant disease that may cause left ventricular hypertrophy...

Heart disease causing cardiac cell death due to ischemia-reperfusion injury is a major cause of morbidity and mortality in the United States. Coronary heart disease and cardiomyopathies are the major cause for congestive heart failure, and thrombosis of the coronary arteries is the most common cause of myocardial infarction. Cardiac injury is followed by post-injury cardiac remodeling or fibrosis. Cardiac fibrosis is characterized by net accumulation of extracellular matrix proteins in the cardiac interstitium and results in both systolic and diastolic dysfunctions...

The mouse is the second mammalian species, after the human, in which substantial amount of the genomic information has been analyzed. With advances in transgenic technology, mutagenesis is now much easier to carry out in mice. Consequently, an increasing number of transgenic mouse systems have been generated for the study of cardiac arrhythmias in ion channelopathies and cardiomyopathies. Mouse hearts are also amenable to physical manipulation such as coronary artery ligation and transverse aortic constriction to induce heart failure, radiofrequency ablation of the AV node to model complete AV block and even implantation of a miniature pacemaker to induce cardiac dyssynchrony...

OBJECTIVE: Doxorubicin (DOX) is an effective anticancer drug but its clinical application is limited because it induces apoptosis in cardiomyocytes and leads to permanent degenerative cardiomyopathy and heart failure possibly due to oxidative stress. Recent studies showed that Capparis spinosa (C. spinose) exhibits potent antioxidant activity. So, in this study, we explored the protective effect of hydro-alcoholic extract of C. spinosa against DOX-induced cytotoxicity in H9c2 cells. MATERIALS AND METHODS: Cell viability was quantified by MTT assay...

OBJECTIVE: To determine whether adverse outcomes were more common in late preterm pregnancies complicated by preeclampsia and growth restriction compared to those affected by preeclampsia alone. METHODS: This was a retrospective cohort study of 8,927 singleton pregnancies with preeclampsia. Pregnancies with small for gestational age (SGA) neonates (birthweight <10(th) percentile) were compared to those appropriate for gestational age (AGA) neonates. Maternal outcomes included cesarean delivery (CD) rate, CD for fetal heart rate (FHR) abnormalities, abruption, postpartum hemorrhage (PPH), maternal transfusion, acute renal failure, and peripartum cardiomyopathy...

Despite advances in supportive and protective therapy for myocardial function, heart failure caused by various clinical conditions, including cardiomyopathy due to antineoplastic therapy, remains a major cause of morbidity and mortality. Because of the limitations associated with current therapies, investigators have been searching for alternative treatments that can effectively repair the damaged heart and permanently restore its function. Damage to the heart can result from both traditional chemotherapeutic agents, such as anthracyclines, and new targeted therapies, such as trastuzumab...
