INTRODUCTION: Pulmonary congestion is a common finding of heart failure (HF), but it remains unclear how pulmonary and heart blood volumes (Vp and Vh) and extravascular lung water (EVLW) change in stable HF and impact lung function. METHODS: Fourteen patients with HF (age: 68±11 y; LVEF: 33±8%) and 12 controls (age: 65±9 y) were recruited. A pulmonary function test, thoracic CT scan, and contrast perfusion scan were performed. From the thoracic scan, a histogram of CT attenuation of lung tissue was generated and skew, kurtosis, and full-width half-max were calculated as surrogates of EVLW...

OBJECTIVES: This study was designed to detect differences in markers associated with incident heart failure preserved ejection fraction (HFpEF) when comparing matched case-control groups. BACKGROUND: Evidence continues to demonstrate increasing prevalence, cost and mortality implications of HFpEF, but clearly defined parameters that distinguish between controls and HFpEF have not been established. METHODS: A study cohort of case (incident patients with HFpEF, n=155) and matched control (patients with no prior HF, n=155) groups was retrospectively identified...

BACKGROUND: The objective was to determine the impact of improving right ventricular versus left ventricular stroke work indices (RVSWI v. LVSWI) during therapy for acute decompensated heart failure (ADHF). METHODS AND RESULTS: Cox proportional hazards regression and logistic regression was used to analyze key factors associated with outcomes in 175 patients (age 56.7 ± 13.6 years, 29.1% female) with hemodynamic data from the Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness (ESCAPE) trial...

With the pervasive use of the internet and social media, the potential applicability toward patients with heart failure (HF) remains understudied. Here, we outline the general use of social media and some early work utilizing social media as well as data from our own Mayo Clinic Center for Social Media experience. Both enterprise-wide social media data as well as those specific to HF-related pages and posts appear to support the preferential use of Facebook and YouTube for potential benefit in patients with HF...

Background The epidemiology of heart failure (HF) is changing. This study aims to describe questions that arise during the routine care of heart failure (HF) patients that are unanswered by the current literature and describe how the type and focus of these questions has changed over time. Methods Investigators from the NHLBI-sponsored Heart Failure Apprentice Network collected and categorized questions from 5 academic hospitals over 12 months. A total of 174 unanswered questions were collected and analyzed...

AIMS: Bile acids (BAs) are now recognized as signaling molecules and emerging evidence suggests that BAs affect cardiovascular function. The gut microbiota has recently been linked to the severity of heart failure (HF), and microbial metabolism has a major impact on BA homeostasis. We aimed to investigate the pattern of BAs, and in particular microbiota-transformed (secondary) BAs, in patients with chronic HF. METHODS AND RESULTS: This was a prospective, observational, single-center study including 142 patients with chronic HF and 20 age- and sex-matched healthy control subjects...

BACKGROUND: Heart failure (HF) is associated with high 30-day readmission rates and places significant financial burden on the health care system. The aim of this study was to determine if the duration of observation on an oral loop diuretic prior to discharge is associated with a reduction in 30-day HF readmission in patients with acute decompensated HF (ADHF). METHODS AND RESULTS: This was a retrospective study of adult patients admitted for ADHF at a large academic medical center...

BACKGROUND: Conversations about goals of care in hospital are important to patients who have advanced heart failure (HF). METHODS: We conducted a multi-centre survey of cardiology nurses, fellows, and cardiologists at 8 Canadian teaching hospitals. The primary outcome was the importance of barriers to goals of care discussions in hospital (1=extremely unimportant; 7=extremely important). We also elicited perspectives on roles of different practitioners in having these conversations...

REVIEW
Dushyanth Srinivasan, Nihar R Desai
In response to wide variation in quality and outcomes as well as escalating health care costs, the U.S. health care system is transitioning away from a volume based payment system to a quality- and value-based system. Medicare, the largest insurer and payer of healthcare, has accelerated the movement towards value-based care with the development and implementation of myriad alternative payment models and pay for performance programs as part of the Affordable Care Act. Given that heart failure affects a significant number of Medicare patients and these patients account for a disproportionate amount of healthcare utilization and spending, heart failure has become a focal point for these initiatives...

BACKGROUND: Heart failure (HF) is associated with chronic sympathetic activation. Renal denervation (RDN) aims to reduce sympathetic activity by ablating the renal sympathetic nerves. We investigated the effect of RDN in patients with chronic HF and concurrent renal dysfunction, in a prospective, multicenter, single-arm feasibility study. METHODS AND RESULTS: Thirty-nine patients with chronic systolic HF (left ventricular ejection fraction [LVEF] <40%, New York Heart Association class II-III,) and renal impairment (estimated glomerular filtration rate [eGFR; assessed with Modification of Diet in Renal Disease equation] <75 mL/min/1...

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...
