Prognosis of morbid obesity patients with advanced heart failure.
Abstract
Obese patients have been noted to have better prognosis in many conditions including heart failure. We hypothesize that this favorable prognosis for obesity may not be seen in patients with morbid obesity and advanced heart failure. A total of 501 consecutive patients with advanced heart failure referred for heart transplant evaluation to the Cleveland Clinic were studied. Patients were categorized into 3 groups based on their body mass index score as nonobese (≤30 kg/m(2) ), obese (30.1-40 kg/m(2) ), and morbidly obese (≥40 kg/m(2) ). There were fewer cardiovascular risk factors in the mor...

Catheter ablation of atrial flutter in patients with left ventricular assist device improves symptoms of right heart failure.
Abstract
Persistent atrial flutter (AFL) in left ventricular assist device (LVAD) recipients can result in loss of AV synchrony, impaired ventricular filling and right heart failure (RHF). The authors report the largest series of HeartMate II (HMII) patients who developed AFL with decompensated RHF, which successfully resolved with AFL ablation. Eight patients with HMII LVAD (mean age, 57±12 years) had medically refractory AFL, with 7 developing de novo AFL after LVAD implant (onset range, 2 days-22 months post-implant). Three patients developed recurrent syncope, 2 had inappropriate implantable cardio...

Decreased readmissions and improved quality of care with the use of an inexpensive checklist in heart failure.
Abstract
Providing effective discharge instructions, appropriate dose uptitration, education regarding heart failure (HF) monitoring, and strict follow-up have all been shown to decrease readmissions for HF but are all underutilized. The authors developed and evaluated the impact of a quality-improvement HF checklist as a tool to remind physicians to improve quality of care in HF patients. The checklist was used in randomly selected patients admitted with a primary diagnosis of acute decompensated HF. It included documentation regarding medications and dose uptitration, relevant counseling, and follow-up i...

Preload reserve is restored in patients with decompensated chronic heart failure who respond to treatment.
Abstract
The authors designed this prospective study to show the relationship between preload reserve and treatment effectiveness of chronic heart failure (CHF). Fifty patients, aged 77±24 years, with decompensated CHF (B-type brain natriuretic peptide [BNP] >1000 pg/mL) were included. Preload reserve was assessed by the changes in contraction indices during a passive leg raise (PLR). Contraction indices were assessed noninvasively using Bioreactance technology. After 4 days of optimized therapy, the same variables were reassessed and treatment-induced differences were calculated. Treatment effective...

Thiamine supplementation for the treatment of heart failure: a review of the literature.
Abstract
A systematic review of the literature was performed by searching Pubmed and EMBASE databases using the terms "thiamine," "vitamin B1," "heart failure," "systolic dysfunction," "ventricular dysfunction," "cardiomyopathy," "ventricular failure," and "systolic failure." Relevant trials and articles were evaluated pertaining to thiamine deficiency in patients with heart failure (HF) and references were searched for further inclusion of articles. A total of 20 articles were reviewed and summarized in detail. While more research is needed to fully elucidate the clinical thiamine deficiency in HF patient...

Serum cystatin C as a biomarker of cardiac diastolic dysfunction in patients with cardiac disease and preserved ejection fraction.
Abstract
Diastolic dysfunction of the heart is correlated with cardiac mortality. Serum cystatin C (CysC) is an endogenous marker of kidney function. It is not clear whether serum CysC is associated with diastolic dysfunction in patients with varying cardiac conditions with concomitant diastolic abnormalities and preserved ejection fraction (EF). The authors measured serum CysC levels in patients with cardiac diseases and examined the relationships between serum CysC levels and diastolic function. Serum CysC was measured and echocardiography was performed in 124 consecutive patients with cardiac diseases. ...

Uremic Cardiomyopathy: An Underdiagnosed Disease.
Abstract
Uremic cardiomyopathy is responsible for high morbidity and mortality rates among patients with chronic kidney disease (CKD) or end-stage renal disease (ESRD); however, the early implementation of hemodialysis may halt its progression. Nonconventional hemodialysis, such as frequent hemodialysis, appears to have an advantage over conventional hemodialysis. Kidney transplantation has been shown to reverse uremic cardiomyopathy and to confer a significant survival advantage over hemodialysis. Targeting future therapies at the underlying cellular mechanisms of uremic cardiomyopathy may finally start t...

Abstract
Resynchronization therapy has become standard of care in patients with left bundle branch block (LBBB), congestive heart failure (CHF), and low ejection fraction (EF). In order to characterize the left ventricular (LV) function evolution in patients with LBBB and baseline preserved LVEF, records of all patients who visited an academic echocardiography laborator...

Can Vitamin D Supplementation Improve the Severity of Congestive Heart Failure?
Abstract
The aim of the present study was to investigate whether vitamin D supplementation could improve biochemical findings and functional capacity of patients with heart failure (HF). One hundred patients with New York Heart Association (NYHA) class I through III HF were included in this prospective study and their 25-hydroxyvitamin D levels were evaluated. Only 6% of the participants had a sufficient serum concentration of 25(OH) D >30 nmol/L. Patients with insufficient or deficient serum levels of 25(OH) D (<30 ng/mL and <20 ng/mL, respectively) received oral vitamin D3 (cholecalciferol) f...

Cerebral Perfusion is Associated With White Matter Hyperintensities in Older Adults With Heart Failure.
This study suggests that reduced cerebral perfusion is associated with greater WMHs in older adults with HF. These findings support the widely proposed mechanism of cognitive impairment in HF patients and prospective studies are needed to confirm these results.

Impact of Epoetin Alfa on Left Ventricular Structure, Function, and Pressure Volume Relations as Assessed by Cardiac Magnetic Resonance: The Heart Failure Preserved Ejection Fraction (HFPEF) Anemia Trial.
Abstract
Anemia, a common comorbidity in older adults with heart failure and a preserved ejection fraction (HFPEF), is associated with worse outcomes. The authors quantified the effect of anemia treatment on left ventricular (LV) structure and function as measured by cardiac magnetic resonance (CMR) imaging. A prospective, randomized single-blind clinical trial (NCT NCT00286182) comparing the safety and efficacy of epoetin alfa vs placebo for 24 weeks in which a subgroup (n=22) had cardiac magnetic resonance imaging (MRI) at baseline and after 3 and 6 months to evaluate changes in cardiac structure and f...

Association Between Weight Loss and Improvement of Ventricular Systolic Function in Advanced Heart Failure.
Abstract
In heart failure (HF), longitudinal changes in ventricular ejection fraction are poorly studied. The authors' objective was to document the dynamic changes in systolic function of both ventricles during acute HF and after a 3-month follow-up period, and to identify factors associated with ventricular improvement. A limited access dataset from the Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness (ESCAPE) trial provided by The National Heart, Lung, and Blood Institute was analyzed. In patients admitted to the hospital with acute HF, both ventricles were...

A Novel Approach to Monitoring Pulmonary Congestion in Heart Failure: Initial Animal and Clinical Experiences Using Remote Dielectric Sensing Technology.
Abstract
Despite current therapies and disease management approaches, rates of heart failure (HF) rehospitalization remain high. New tools are needed to assess preclinical (asymptomatic) pulmonary congestion to enable outpatient management. Hence, a novel monitoring system based on noninvasive remote dielectric sensing (ReDS) technology was developed. Validation of the ReDS technology was conducted in preclinical and clinical studies. In a porcine HF model, acute fluid overload followed by administration of diuretics were performed. Changes in ReDS values were correlated to serial computed tomographic (CT)...
