A consensus conference was convened to define the current state and important gaps in knowledge and needed research on "Palliative and Supportive Care in Advanced Heart Failure." ⋯ The conference identified gaps in current knowledge, practice, and research relating to prognostication, symptom management, and supportive care for advanced heart failure (HF). Specific conclusions include: (1) although supportive care should be integrated throughout treatment of patients with advanced HF, data are needed to understand how to best decrease physical and psychosocial burdens of advanced HF and to meet patient and family needs; (2) prognostication in advanced HF is difficult and data are needed to understand which patients will benefit from which interventions and how best to counsel patients with advanced HF; (3) research is needed to identify which interventions improve quality of life and best achieve the outcomes desired by patients and family members; (4) care should be coordinated between sites of care, and barriers to evidence-based practice must be addressed programmatically; and (5) more research is needed to identify the content and technique of communicating prognosis and treatment options with patients with advanced HF; physicians caring for patients with advanced HF must develop skills to better integrate the patient's preferences into the goals of care.

Review Comparative Study
A comparative analysis of the results from 4 trials of beta-blocker therapy for heart failure: BEST, CIBIS-II, MERIT-HF, and COPERNICUS.
Recent large randomized, controlled trials (BEST [Beta-blocker Evaluation of Survival Trial], CIBIS-II [Cardiac Insufficiency Bisoprolol Trial II], COPERNICUS [Carvedilol Prospective Randomized Cumulative Survival Study], and MERIT-HF [Metoprolol Randomized Intervention Trial in Congestive Heart Failure]) have addressed the usefulness of beta-blockade in the treatment of advanced heart failure. CIBIS-II, COPERNICUS, and MERIT-HF have shown that beta-blocker treatment with bisoprolol, carvedilol, and metoprolol XL, respectively, reduce mortality in advanced heart failure patients, whereas BEST found a statistically nonsignificant trend toward reduced mortality with bucindolol. We conducted a post hoc analysis to determine whether the response to beta-blockade in BEST could be related to differences in the clinical and demographic characteristics of the study populations. We generated a sample from BEST to resemble the patient cohorts studied in CIBIS-II and MERIT-HF to find out whether the response to beta-blocker therapy was similar to that reported in the other trials. These findings are further compared with COPERNICUS, which entered patients with more severe heart failure. ⋯ Although not excluding the possibility of differences resulting from chance alone or to different properties among beta-blockers, this study suggests the possibility that different heart failure population subgroups may have different responses to beta-blocker therapy.

Randomized Controlled Trial Clinical Trial
Effect of Valsartan on hospitalization: results from Val-HeFT.
Although current therapies have improved heart failure (HF) outcome, hospitalizations continue at high rates. The Valsartan Heart Failure Trial (Val-HeFT) showed that valsartan reduced the risk of first worsening HF hospitalization by 27.5% versus placebo (P <.001). This article analyzes all-cause and investigator-assessed HF hospitalization in Val-HeFT overall and in subgroups defined by preexisting HF therapy. ⋯ Addition of valsartan to prescribed HF therapy demonstrated significant reductions in HF hospitalizations and was particularly beneficial in reducing recurrent HF hospitalization.

Differences in mortality are thought to exist between African Americans and Caucasians with heart failure. These differences may be due to a variety of factors, including differences in disease process, socioeconomic status, and access to health care. Additionally, little data exist on racial differences between these two groups after cardiac transplantation. This study examines a single center, urban experience in treating African Americans and Caucasians with heart failure and after cardiac transplantation. We hypothesize that treatment in a specialized, comprehensive heart failure/cardiac transplantation program results in similar survival between African Americans and Caucasians. ⋯ Delivery of care to heart failure patients in a comprehensive, specialized program results in similar survival regardless of race despite higher utilization of inpatient and outpatient resources. The finding that, after cardiac transplantation, African Americans do not have higher mortality rates, despite having higher rates of rejection overall and more hospitalizations, further supports the hypothesis that optimal care can improve outcomes despite unfavorable baseline clinical characteristics.

Randomized Controlled Trial Clinical Trial
African-American Heart Failure Trial (A-HeFT): rationale, design, and methodology.
Hydralazine and isosorbide dinitrate combination (H+ISDN), angiotensin-converting enzyme inhibitors, and beta-blockers have improved outcomes in heart failure (HF). Analysis of previous trials has shown that H+ISDN appears especially beneficial in African American patients. ⋯ In addition to providing additional information on BiDil efficacy in HF, A-HeFT is the first HF trial aimed at a selected subgroup of patients and the first to use a new composite HF score as its primary efficacy endpoint.
