High prevalence of anemia in heart failure with preserved left ventricular ejection fraction (HFpEF) has been reported. However, little is known about the association of anemia and gender with prognosis in HFpEF patients. In addition, effective blood hemoglobin (Hb) level for prognosis in HFpEF patients remains largely unknown. In this study, we investigated the association between anemia, gender, and prognosis in 535 HFpEF patients enrolled in Japanese heart failure syndrome with preserved ejection fraction registry. Furthermore, we assessed effective blood Hb level to predict prognosis in HFpEF patients. According to the World Health Organization criteria, the prevalence rate of anemia on admission was about 70% in both male and female HFpEF patients. Kaplan–Meier analysis for all-cause mortality demonstrated that anemic patients had poor prognosis compared with non-anemic patients in both male and female HFpEF patients. Interestingly, multivariate analysis revealed that blood Hb level at discharge was an independent predictor of all-cause mortality in both male and female HFpEF patients. According to survival classification and regression tree analysis, blood Hb level at discharge of 9.4 g/dL for male and 12.3 g/dL for female was more accurate cutoff value to predict all-cause mortality in HFpEF patients. Anemia was implicated in poor prognosis in both male and female HFpEF patients. In particular, blood Hb level at discharge was an independent predictor of all-cause mortality in both male and female HFpEF patients. Effective cutoff value of blood Hb level at discharge to predict all-cause mortality was lower in male than in female HFpEF patients. [ABSTRACT FROM AUTHOR]

Recently, we and other group have reported that furosemide administration along with hypertonic saline solution enhanced diuretic efficiency of furosemide. However, little is known about factors which associated with high diuretic efficiency by hypertonic saline solution with furosemide therapy. To identify predictors of diuretic efficiency in the hypertonic saline solution with furosemide therapy, we recruited 30 consecutive hospitalized heart failure (HF) patients with volume overload (77 ± 10 years, systolic blood pressure > 90 mmHg, and estimated glomerular filtration rate > 15 ml/min/1.73 m2). Hypertonic saline with furosemide solution, consisting of 500 ml of 1.7% hypertonic saline solution with 40 mg of furosemide, was administered continuously over 24 h. The patients were divided into two groups on the basis of 24-h urine volume (UV) after initiation of diuretic treatment ≥ 2000 ml (high urine volume: HUV) and < 2000 ml (low urine volume: LUV). The basal clinical characteristics of both groups were analyzed and the predictors of HUV after receiving the treatment were identified. There were not significant differences between two groups in baseline clinical characteristics and medication. Univariate logistic analysis revealed that blood urea nitrogen/creatinine ratio, urine urea nitrogen/creatinine ratio (UUN/UCre), fractional excretion of sodium, and tricuspid annular plane systolic excursion positively associated with HUV. Multivariate logistic regression analysis revealed that UUN/UCre at baseline was independently associated with HUV, and UUN/UCre best predicts HUV by the therapy with a cut-off value of 6.16 g/dl/g Cre (AUC 0.910, 95% CI 0.696-0.999, sensitivity 80%, specificity 87%). The Kaplan-Meier curves revealed significant difference for HF rehospitalization and death rate at 180 days between patients with UUN/UCre ≥ 6.16 g/dl/g Cre and those with UUN/UCre < 6.16 g/dl/g Cre (log-rank P = 0.0489). UUN/UCre at baseline strongly predicted of diuretic efficiency in the hypertonic saline solution with furosemide therapy, and was associated with HF prognosis. [ABSTRACT FROM AUTHOR]

Background: Diuretic response is a strong predictor of outcome for admitted patients of acute decompensated heart failure (ADHF). However, little is known about the effects of early diuretic response to carperitide. Methods: We retrospectively analyzed records of 85 patients hospitalized for ADHF who received carperitide as initial treatment and <40 mg furosemide during the early period. The eligible patients were divided into good diuretic responder (GR) group and poor diuretic responder (PR) group on the basis of median urinary volume. Results: The PR group demonstrated older age, lower body mass index (BMI), lower estimated glomerular filtration rate, and higher blood urea nitrogen (BUN) level, left ventricular ejection fraction, and β-blockers prescribed at baseline than the GR group. The incidence of worsening renal function (WRF) was significantly higher in the PR group than in the GR group. There was no correlation between early intravenous furosemide dose and urinary volume (Spearman correlation, ρ = 0.111, p = 0.312). Multivariate analysis showed that the statistically significant independent factors associated with poor diuretic response to carperitide were BMI (Odds ratio (OR) = 0.82, 95% confidence interval (CI) 0.68–0.94, p = 0.004) and BUN (OR = 1.07, 95%CI 1.01–1.15, p = 0.018). Kaplan–Meier analysis indicated a lower event-free rate in the PR group than in the GR group (log-rank, p = 0.007). Conclusions: BMI and BUN levels on admission were significant determinants of early poor diuretic response to carperitide. Early poor diuretic response to carperitide was associated with future poor outcomes. [ABSTRACT FROM AUTHOR]

Hypertonic saline with furosemide has been proposed for a long time as an effective therapeutic option for the treatment of acute decompensated heart failure (ADHF). We previously reported the efficacy of continuous infusion of 1.7 % hypertonic saline plus low-dose furosemide in treatment for ADHF. Although this therapeutic strategy can be a useful option for effective decongestion in treatment for ADHF, there is no study that assesses the effect and safety of saline supplementation compared with standard therapy in Japan. The aim of this study was to investigate the efficacy, safety, and cost-effectiveness of 1.7 % hypertonic saline plus low-dose furosemide infusion compared with carperitide. We compared clinical outcomes, adverse events, and cost for patients receiving carperitide (carperitide group) with those for patients receiving 1.7 % hypertonic saline plus low-dose furosemide (salt group) during the initial hospitalization for ADHF. The cost analysis was performed on the basis of the previous report about cost-effectiveness of acute heart failure. A total of 175 ADHF patients received either carperitide ( n = 111) or 1.7 % hypertonic saline plus low-dose furosemide infusion ( n = 64) as initial treatment. There were no differences in length of hospital stay (27 ± 19 vs. 25 ± 16 day, p = 0.170) and infusion period (7.2 ± 6.1 vs. 8.4 ± 7.5 day, p = 0.474) between the two groups. The incidence of rehospitalization did not differ at 1 month (7.6 vs. 6.6 %, p = 1.000) and 1 year (36.8 vs. 37.7 %, p = 0.907) between the two groups. The Kaplan-Meier curves revealed no significant difference for 1 year all-cause mortality between the two groups (log-rank, p = 0.724). The single hospitalization cost was 95,314 yen lower and the yearly hospitalization cost 125,628 yen lower in the salt group compared with the carperitide group. Thus, intravenous 1.7 % hypertonic saline plus low-dose furosemide infusion is as effective as carperitide in terms of clinical outcome and is a cost-effective therapeutic strategy for the treatment of ADHF.
