Use of Left Ventricular Assist Device (HeartMate II): A Singapore Experience
We report our experience with the HeartMate II (HMII) LVAD (Thoratec Corporation, Pleasanton, CA, USA) as a bridge‐to‐heart transplant in our center from 2009 to 2012. This was a retrospective review of 23 consecutive patients who underwent HMII LVAD implantation in our center between May 2009 and December 2012. All patients were classified as Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) levels 1 to 3 and underwent LVAD implantation as a bridge‐to‐heart transplant. There were 17 male and 6 female patients. The mean age was 43.6 years old (range 14 to 64). The etiologies of heart fa...

Cardiac MRI assessment of atrial fibrosis in atrial fibrillation: implications for diagnosis and therapy
Atrial fibrillation (AF) is the most commonly encountered cardiac arrhythmia in clinical practice, with a prevalence of 0.4–1% in the US population.w1 AF is a potent risk factor, increasing the risk of stroke fivefold and accounting for approximately 15% of all strokes in the USA.w2 AF also significantly increases the risk of mortality from heart failure.w3–7 Many therapies, including pharmacological approaches and direct current cardioversion, have been tried to treat this malignant arrhythmia, but were not found to be that effective.1 w8–w11 Catheter ablation of AF has provided better outcomes compared ...

Sudden unexpected death in schizophrenia: Autopsy findings in psychiatric inpatients
In conclusion, sudden cardiac death occurs at a 0.8% rate in a psychiatric hospital, well above general population rates. Autopsy findings indicate that sudden death in schizophrenia is caused by structural cardiovascular, respiratory and neurological abnormalities, with most cases due to acute myocardial infarction. Early recognition and treatment of coronary artery disease must become a clinical priority for all adults with schizophrenia.

Atorvastatin improves systolic function, but does not prevent the development of dilated cardiomyopathy in streptozotocin-induced diabetic rats
Conclusions: Whereas atorvastatin does not reverse ventricular dilatation, it does have a positive hemodynamic effect on the CV system of diabetic rats. This hemodynamic benefit is independent of cholesterol levels, and is observed concomitantly with reduced oxidative stress, vascular remodeling, and improved endothelial function. Together, these results suggest that atorvastatin decreases the workload on the heart and improves systolic performance in type 1 diabetic rats by reducing oxidative stress, vascular tone, and systemic vascular resistance.

Temporary right ventricular support following left ventricle assist device implantation: a comparison of two techniques
CONCLUSIONS Temporary support of the failing RV after LVAD implantation using temporary vein and the pulmonary artery RVAD is a promising therapeutic option. This approach provides adequate LVAD pre- and afterload and is associated with significantly less thromboembolic complications.

Predictors of Mortality in Pediatric Patients on Venoarterial Extracorporeal Membrane Oxygenation*
Objectives: Currently, there are no established echocardiographic or hemodynamic predictors of mortality after weaning venoarterial extracorporeal membrane oxygenation in children. We wished to determine which measurements predict mortality. Design: Over 3 years, we prospectively assessed six echo and six hemodynamic variables at 3–5 circuit rates while weaning extracorporeal membrane oxygenation flow. Hemodynamic measurements were heart rate, inotropic score, arteriovenous oxygen difference, pulse pressure, oxygenation index, and lactate. Echo variables included shortening/ejection fraction, outflow tract Doppler-derive...

Adipose tissue-derived stem cells as a therapeutic tool for cardiovascular disease.
Abstract Adipose tissue-derived stem cells (ADSCs) are adult stem cells that can be easily harvested from subcutaneous adipose tissue. Many studies have demonstrated that ADSCs differentiate into vascular endothelial cells (VECs), vascular smooth muscle cells (VSMCs), and cardiomyocytes in vitro and in vivo. However, ADSCs may fuse with tissue-resident cells and obtain the corresponding characteristics of those cells. If fusion occurs, ADSCs may express markers of VECs, VSMCs, and cardiomyocytes without direct differentiation into these cell types. ADSCs also produce a variety of paracrine factors such as vascular...

Relationship between Myocardial Extracellular Space Expansion Estimated with Post-Contrast T1 Mapping MRI and Left Ventricular Remodeling and Neurohormonal Activation in Patients with Dilated Cardiomyopathy.
CONCLUSION: Post-contrast T1 is closely related to LV remodeling, diastolic function, and neurohormonal activation in patients with DCM. PMID: 26355278 [PubMed - in process]

Major depressive disorder in chronic heart failure patients: Does silent cerebral infarction cause major depressive disorder in this patient population?
CONCLUSION: CHF patients have an increased prevalence of SCI and MDD. Patients with SCI have a higher prevalence of MDD compared to patients without SCI in CHF. PMID: 26363742 [PubMed - in process]

Direct epicardial assist device using artificial rubber muscle in a swine model of pediatric dilated cardiomyopathy.
CONCLUSIONS: Use of a circumferential direct epicardial assistant device resulted in improvement in hemodynamic data in a dilated cardiomyopathy model. Although there is still a need for improvements in device components, the direct cardiac assist device may be a good alternative to recent heart failure device therapies.

MELAS syndrome and cardiomyopathy: linking mitochondrial function to heart failure pathogenesis
Abstract Heart failure remains an important clinical burden, and mitochondrial dysfunction plays a key role in its pathogenesis. The heart has a high metabolic demand, and mitochondrial function is a key determinant of myocardial performance. In mitochondrial disorders, hypertrophic remodeling is the early pattern of cardiomyopathy with progression to dilated cardiomyopathy, conduction defects and ventricular pre-excitation occurring in a significant proportion of patients. Cardiac dysfunction occurs in approximately a third of patients with mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like e...

The potential influence of atherogenic dyslipidemia on the severity of chronic Chagas heart disease
Conclusion: we observed that AI correlated with CCHD stages and contributed, in association with anti-B13 antibodies and age, to the prediction of systolic heart failure.RESUMO Introducción: la miocardiopatía chagásica (MCC) es la manifestación más común de la tripanosomiasis americana, causando cerca de 50.000 muertes al año. Varios factores se asocian con la gravedad de MCC. Sin embargo, la evaluación de la contribución de los principales factores de riesgo cardiovascular (FRC), como la hipertensión y la dislipidemia aterogénica (DA), a la gravedad de la MCC es escasa, a pesar de su papel bien establecido en l...
