BACKGROUND: The presence of giant ring mitochondria on endomyocardial biopsy is rarely reported and does not have a well-defined differential diagnosis. METHODS: We report the case of a 54-year-old man with heart failure with preserved ejection fraction and left ventricular hypertrophy, initially thought to have an infiltrative cardiomyopathy. RESULTS: The patient was found to have extensive vacuolization caused by the presence of giant ring mitochondria on endomyocardial biopsy...

AIMS: To understand the pattern and outcomes for heart failure (HF) related hospitalization among Indigenous and non-Indigenous patients living in Central Australia. METHODS AND RESULTS: A retrospective analysis of administrative data for patients presenting with a primary or secondary diagnosis of HF to Central Australia's Alice Springs Hospital during 2008 to 2012 was performed. The population rate of admission and subsequent outcomes (including case-fatality and readmission) during the 5-year study period were examined...

BACKGROUND: Until recently, transplantation from hepatitis C positive donors was relatively contraindicated as eradication of active hepatitis C previously required an interferon-based regimen which has been associated with rejection in solid organ transplantation. New interferon-free treatment regimens for hepatitis C have fewer adverse events and higher cure rates than interferon-based regimens. Interferon-free regimens have been shown to be safe in the liver transplantation literature but little is known about the safety and efficacy of treatment in heart transplantation...

BACKGROUND: The utility of intra-aortic balloon counterpulsation pumps (IABPs) in low cardiac output states is unknown and no studies have explored the impact of IABP therapy on ventricular workload in patients with advanced HF. For these reasons, we explored the acute hemodynamic effects of IABP therapy in patients with advanced HF. METHODS: We prospectively studied 10 consecutive patients with Stage D HF referred for IABP placement prior to LVAD surgery and compared to five control patients with preserved left ventricular (LV) ejection fraction (EF) who did not receive IABP therapy...

The discovery of induced pluripotent stem cells (iPSCs) has revolutionized regenerative medicine. Autologous iPSCs can be generated by introducing 4 stem cell-specific factors (Oct4, Sox2, Klf4, c-Myc) into fibroblasts. iPSCs can propagate indefinitely and differentiate into clinically important cell types including cardiomyocytes, in vitro. The iPSC-derived cardiomyocytes represent a promising source of cells for cell-based therapeutic approaches for cardiac regeneration. However, there are several challenges in the clinical application of iPSCs: tumorigenicity of immature cells, poor survival of the transplanted myocardial cells, and cost and efficacy of this therapeutic approach...

BACKGROUND: Obesity is a known risk factor for heart failure. The prevalence of both conditions has increased in Sweden the last decades. Obesity surgery has been shown to improve cardiac function. We therefore investigated whether the risk of heart failure was lower in obese patients after bariatric surgery compared with obese patients without surgical intervention. METHODS AND RESULTS: From the Swedish National Patient Registry we created a cohort including 47,859 patients aged 18-74 years with a primary diagnosis of obesity from 2000 to 2011...

BACKGROUND: Heart failure (HF) disproportionately affects older adults. Dietary sodium indiscretion is frequently implicated in HF decompensation. The affinity for and ability to taste salt in this process is unexplored. We sought to evaluate differences in salt taste by age and HF diagnosis and to map changes after hospitalization for acute decompensated heart failure (ADHF). METHODS: Seventy-two subjects underwent initial salt-taste testing during hospitalization for ADHF...

BACKGROUND: The impact of inspiratory muscle training (IMT) on respiratory and peripheral muscle oxygenation and perfusion during inspiratory muscle fatigue in patients with chronic heart failure has not been established. METHODS AND RESULTS: Twenty-six patients with chronic heart failure were randomly assigned to either 8 weeks of IMT or to a control group. Inspiratory fatigue was induced by a progressive inspiratory resistive loading protocol until there was an inability to sustain inspiratory pressure, when the inspiratory muscle metaboreflex should be activated...

BACKGROUND: Clinical risk factors associated with heart failure (HF) symptoms in aortic stenosis (AS) patients with preserved ejection fraction (EF) have not been fully identified. We hypothesized that left ventricular (LV) diastolic stiffness is associated with HF symptoms in patients with AS. METHODS AND RESULTS: We retrospectively evaluated 275 patients with at least moderate AS (aortic valve area < 1.5cm(2)) and preserved EF (EF ≥50%). LV diastolic stiffness was evaluated using echocardiographic parameters, diastolic wall strain (DWS, a measure of LV wall stiffness) and KLV (a marker of LV chamber stiffness)...
