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...

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 patients, recent evidence has indicated that supplementing with thiamine in HF patients has the potential to improve left ventricular ejection fraction...

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...

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 instructions at discharge...

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)...

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) )...

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 to reduce the burden of uremic cardiomyopathy in the CKD and ESRD population...

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 laboratory during a period of 4 years were retrospectively investigated. Patients were included if they had a baseline EF >50%, LBBB on surface electrocardiography, and at least one follow-up echocardiogram no earlier than 3 months after the baseline study...

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 function...

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) for a total period of 4 months...

Cognitive impairment is common in heart failure (HF) and believed to be the result of cerebral hypoperfusion and subsequent brain changes including white matter hyperintensities (WMHs). The current study examined the association between cerebral blood flow and WMHs in patients with HF and the relationship between WMHs and cognitive impairment. Sixty-nine patients with HF completed the Mini-Mental State Examination (MMSE) and underwent echocardiography, transcranial Doppler sonography for cerebral blood flow velocity of the middle cerebral artery, and brain magnetic resonance imaging...

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...

Worsening renal function (WRF) during treatment of acute decompensated heart failure (ADHF) is generally associated with adverse outcomes. An increase ≥0.3 mg/dL in creatinine level is widely used as the definition of WRF. The authors sought to determine the level of agreement between WRF based on changes in creatinine and changes in cystatin C (CysC) by analyzing data from 121 ADHF patients with available admission and day 3 creatinine and CysC levels. Admission creatinine and CysC levels were 1.39 (0.98-2...

REVIEW
Jeffrey Voigt, Michael Mosier
It has been assumed that less intense levels of care for managing heart failure result in a lowering of the overall costs for this care in the United States. The objective of this review was to determine whether this assumption is correct. A systematic review was performed using Medline, technology assessment Web sites, and relevant cardiovascular and heart failure journals from the year 2000 to the present. US randomized controlled trials where costs were evaluated as one of the endpoints were included. Data were collected using Cochrane Review characteristics of included studies and risk of bias assessment forms...

Self-management intervention is a good method to improve self-care ability, as such, to promote quality of life. However, the research focused on self-management intervention in heart failure patients in Taiwan is very limited. Therefore, the purposes of this study were to test the effectiveness of self-management intervention in patients with heart failure in Taiwan and examine the relationship between self-care ability and quality of life. A quasi-experimental design was used in this study with convenience sampling...

Iron insufficiency has been associated with heart failure, but the impact of a reduction of hemoglobin content in the erythrocytes as estimated by mean corpuscular hemoglobin concentration (MCHC) to myocardial structure, performance, and long-term clinical outcomes has not been well-established. The authors examined hematologic data and long-term outcomes of 197 ambulatory patients with chronic systolic and symptomatic heart failure who underwent comprehensive echocardiographic evaluation. The authors observed that relative hypochromia (defined as low MCHC) was associated with higher natriuretic peptide levels (NT-proBNP, r =-0...

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...
