Usefulness of cell-mediated immune function in risk stratification for patients with advanced heart failure.

Unlabelled: Although heightened inflammation and autoimmune responses have been well described in patients with heart failure, the role of cell-mediated immune function in the pathogenesis and progression of heart failure is unclear. The aim of our study is to evaluate the prognostic role of cell-mediated immune function in patients with advanced heart failure.

Methods: We studied patients with advanced heart failure referred for evaluation of candidacy for advanced heart failure therapies between 2007 and 2010.

Usefulness of neutrophil-to-lymphocyte ratio in risk stratification of patients with advanced heart failure.

Elevated neutrophil-to-lymphocyte ratio (NLR) has been associated with increased mortality in patients with acute heart failure (HF) and neoplastic diseases. We investigated the association between NLR and mortality or cardiac transplantation in a retrospective cohort of 527 patients presented to the Cleveland Clinic for evaluation of advanced HF therapy options from 2007 to 2010. Patients were divided according to low, intermediate, and high tertiles of NLR and were followed longitudinally for time to all-cause mortality or heart transplantation (primary outcome).

Prognosis of morbid obesity patients with advanced heart failure.

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.

Progressive rise in red cell distribution width is associated with disease progression in ambulatory patients with chronic heart failure.

Background: Single red cell distribution width (RDW) assessment is a consistent prognostic marker of poor outcomes in heart failure as well as in other patient cohorts. The objective of this study was to determine the prognostic value of sequential RDW assessment in ambulatory patients with chronic heart failure.

Methods And Results: We reviewed 6,159 consecutive ambulatory patients with chronic heart failure between 2001-2006 and examined changes in RDW values from baseline to 1-year follow-up.

Meta-analysis of randomized controlled trials of statins versus placebo in patients with heart failure.

Although statins have been shown to improve outcomes in retrospective analyses of patients with heart failure (HF), recent randomized placebo-controlled trials have shown mixed results. The goal of this study was to systematically review randomized trials comparing statins to placebo for HF and compare the impact of different statins. CENTRAL, mRCT, and PubMed were searched for eligible studies that prospectively randomized patients with HF to statins or placebo.

Relation of blood urea nitrogen to long-term mortality in patients with heart failure.

Patients with chronic kidney disease and heart failure (HF) have been shown to be at higher risk for major adverse cardiovascular events and death. Recent studies have demonstrated that blood urea nitrogen (BUN) might serve as a powerful predictor of mortality in acutely decompensated HF. The goal of this study was to determine the impact of BUN on long-term mortality in patients with stage B and C HF.
