- Monocytes play a critical role in the pathophysiology of heart failure (HF), but few studies have evaluated the prognostic implications of an increased monocyte count in patients with HF and reduced ejection fraction (EF). The Efficacy of Vasopressin Antagonism in Heart Failure Outcome Study with Tolvaptan (EVEREST) examined the effects of tolvaptan in patients with worsening HF and EF /=800/mul. Patients with increased monocyte count tended to have an increased EF and were less likely to have a history of diabetes mellitus, hypercholesterolemia, or coronary revascularization but were more likely to have higher HF functional class and to be taking HF therapies such as diuretics, angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, and digoxin (p <0.05 for all comparisons). At median follow-up of 9.9 months, increased monocyte count was predictive of all-cause mortality (hazard ratio 1.27, 95% confidence interval 1.003 to 1.60, p = 0.047) but was not associated with cardiovascular mortality or HF hospitalization (hazard ratio 1.06, 95% confidence interval 0.87 to 1.30, p = 0.55). Similar results were seen when monocyte count was analyzed as a continuous variable. However, after adjustment for baseline clinical risk factors, monocyte count was not predictive of either primary end point. In conclusion, increased monocyte count occurs in a minority of patients hospitalized with HF and is associated with poor postdischarge prognosis. However, it does not contribute prognostic value above other more traditional risk factors.

- Women have traditionally been underrepresented in heart failure (HF) trials, and their baseline characteristics and outcomes after hospitalization for HF are unclear. We retrospectively analyzed the clinical characteristics and outcomes of patients according to gender in the Efficacy of Vasopressin Antagonism in Heart Failure Outcome Study with Tolvaptan (EVEREST) trial. EVEREST randomized 4,133 patients hospitalized for HF and ejection fraction of 0.30). Despite a high event rate, no difference was seen in all-cause mortality (men 27% vs women 24%, multivariate hazard ratio 1.04, p = 0.61) or cardiovascular mortality plus HF hospitalization (men 42% vs women 39%, multivariate hazard ratio 1.11, p = 0.10) on univariate analysis or after adjusting for baseline covariates. In conclusion, women hospitalized for worsening HF with an ejection fraction of

- In observational studies of patients hospitalized for heart failure (HHF), risk of death is highest immediately after discharge and decreases over time. It is unclear whether this population risk trajectory reflects (1) lowering of individual patient mortality risk with increasing time from index hospitalization or (2) temporal changes in population case-mix with earlier postdischarge death for "sicker" patients. Survival rate and longitudinal models were used to estimate temporal changes in postdischarge all-cause mortality risk in 3,993 HHF patients discharged alive in the Efficacy of Vasopressin Antagonism in Heart Failure Outcome Study with, Tolvaptan (EVEREST) trial. After median 'follow-up of 9.9 months, 971 patients died (24.2%). Predicted mortality rate decreased from 15.9 per 100 patient-years immediately after discharge to 13.4 at 30 days and 12.8 at 90 days; mortality rate increased steadily thereafter. Risk variation between quintiles of risk was considerably larger than the temporal variation within risk strata. In a longitudinal model serially reassessing predicted patient mortality risk after each follow-up visit using data collected at these visits, predicted mortality risk increased during the 90 days preceding subsequent heart failure readmission and then followed' a postdischarge trajectory similar to the index admission. In conclusion, although there is transiently elevated individual patient risk in the 90 days before and after discharge, the patient's individual risk profile, rather than temporal change in risk relative to hospitalization, remains the main determinant of mortality. For purposes of reducing all-cause mortality in HF patients, preventative and therapeutic measures may be best implemented as long-term interventions for high mortality risk patients based on serial risk assessments, irrespective of recent hospitalization.

- Both hyperkalemia and hypokalemia may be related to heart failure (HF) therapy and are associated with adverse outcomes. Abnormalities in serum potassium levels in hospitalized patients with HF and reduced ejection fraction (EF) have not been previously investigated. A post hoc analysis was performed in 1,907 hospitalized patients with worsening HF and reduced EF in the placebo arm of the Efficacy of Vasopressin Antagonism in HF Outcome Study with Tolvaptan (EVEREST) trial. Serum potassium was measured at randomization and at discharge or day 7. The co-primary end points were all-cause mortality (ACM) and cardiovascular mortality or the first HF hospitalization (CVM + HFH). The association between inhospital change in potassium levels and time to outcomes was evaluated using multivariate Cox regression models. Study participants had a mean age of 65.6 +/- 12.0 years and were on optimal guideline-directed medical therapies, including beta blockers (77%), angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (85%), and aldosterone antagonists (55%). Baseline potassium concentration was 4.3 +/- 0.6 mEq/l, and hyperkalemia or hypokalemia was seen in 6.5% of the participants. On average, serum potassium level increased by 0.21 +/- 0.66 mEq/l, p < 0.0001, during hospitalization. Inhospital potassium change was not associated with either the primary or the secondary end point over a median follow-up of 9.9 months. In conclusion, in patients with reduced EF hospitalized for worsening HF, serum potassium abnormalities are common at baseline (within 48 hours of admission) and potassium levels increase during hospitalization, despite aggressive diuretic therapy. However, they are not associated with all-cause or CVM or HFH. Inhospital changes in potassium may limit the implementation of evidence-based therapies such as mineralocorticoid receptor antagonists.

- We investigated the clinical profiles associated with serum uric acid (sUA) levels in a large cohort of patients hospitalized for worsening chronic heart failure with ejection fraction (EF) /=30 ml/min/1.73 m(2), sUA was strongly associated with increased all-cause mortality (hazard ratio 1.44, 95% confidence interval 1.22 to 1.69, p <0.001) and the composite end point (hazard ratio 1.44, 95% confidence interval 1.26 to 1.64, p <0.001). However, in patients with estimated glomerular filtration rate <30 ml/min/1.73 m(2), sUA was not related with either end point (both p >0.4). Adjusted interaction analyses for gender, race, and admission allopurinol use were not significant. In conclusion, sUA is commonly elevated in patients hospitalized for worsening chronic heart failure and reduced EF, especially in men and blacks. The prognostic use of sUA differs by baseline renal function, suggesting different biologic and pathophysiologic significance of sUA among those with and without significant renal dysfunction.
