- AimsA-type and B-type natriuretic peptides are established markers in chronic heart failure (HF). C-type natriuretic peptide (CNP) belongs to the same peptide family, but is predominantly localized in the endothelium. The prognostic role of CNP in heart failure has not been established. The aim of the study was to determine the prognostic power and clinical correlates of the N-terminal part of pro CNP (NT-proCNP) in patients with chronic HF. Methods and resultsIn 567 hospitalized heart failure patients, NT-proCNP levels were measured at hospital discharge. The primary endpoint was a combined endpoint of all-cause mortality and HF hospitalization after 18 months. Heart failure with a preserved ejection fraction (HFpEF) was pre-defined as an LVEF greater than40%. Mean (SD) age was 71 +/- 11years, 62% were male, mean LVEF was 32 +/- 14%, and 23% had HFpEF. In multivariate linear regression, NT-proCNP levels showed a positive correlation with NT-proBNP levels and parameters of renal function, whereas a negative correlation with female sex and vascular endothelial growth factor was observed. After 18 months follow-up, 240 patients reached the combined endpoint. We observed interaction between NT-proCNP and LVEF for outcome (P=0.046). Multivariate analyses revealed NT-proCNP to be strongly predictive for the primary endpoint [hazard ratio (HR) 1.78, 95% confidence interval (CI) 1.18-2.67, P=0.006) in patients with HFpEF, but not in patients with a reduced ejection fraction (HFrEF) (HR 1.07, 95% CI 0.81-1.43, P=0.616). Finally, reclassification showed significant additive value in patients with HFpEF (Pless than0.001), but not in those with HFrEF (P=0.453). Conclusionless thanp id="ejhf140-para-0003"greater thanNT-proCNP is a strong independent marker for outcome in patients with HFpEF, but not in those with HFrEF.

- AimsIt has been suggested that home-based heart failure (HF) management in primary care may be an alternative to clinic-based management in HF patients. However, little is known about adherence to HF guidelines and adherence to the medication regimen in these home-based programmes. The aim of the current study was to determine whether long-term follow-up and treatment in primary care is equally effective as follow-up at a specialized HF clinic in terms of guideline adherence and patient adherence, in HF patients initially managed and up-titrated to optimal treatment at a specialized HF clinic. Methods and resultsWe conducted a multicentre, randomized, controlled study in 189 HF patients (62% male, age 72 11 years), who were assigned to follow-up either in primary care (n = 97) or in a HF clinic (n = 92). After 12 months, no differences between guideline adherence, as estimated by the Guideline Adherence Indicator (GAI-3), and patient adherence, in terms of the medication possession ratio (MPR), were found between treatment groups. There was no difference in the number of deaths (n = 12 in primary care and n = 8 in the HF clinic; P = 0.48), and hospital readmissions for cardiovascular (CV) reasons were also similar. The total number of unplanned non-CV hospital readmissions, however, tended to be higher in the primary care group (n = 22) than in the HF clinic group (n = 10; P = 0.05). Conclusionsless thanp id="ejhf173-para-0003"greater thanPatients discharged after initial management in a specialized HF clinic can be discharged to primary care for long-term follow-up with regard to maintaining guideline adherence and patient adherence. However, the complexity of the HF syndrome and its associated co-morbidities requires continuous monitoring. Close collaboration between healthcare providers will be crucial in order to provide HF patients with optimal, integrated care.

- Background: Thirst is often increased in patients with heart failure (HF) and can cause distress during the course of the condition. The aim of the present study was to describe the trajectory of thirst during an 18-month period and to identify variables associated with persistent thirst in patients with HF. Methods and Results: Data were collected from 649 patients with HF with the use of the Revised Heart Failure Compliance Scale at 1, 6, 12, and 18 months after a period of hospital treatment for worsening HF. Thirst trajectory was described for the 4 follow-up visits and logistic regression analysis was used to identify factors independently associated with persistent thirst. In total, 33% (n = 212) of the patients reported thirst on greater than= 1 occasions and 34% (n = 46) continued to have thirst at every follow-up visit. Nineteen percent (n = 121) of the patients had persistent thirst. Patients with persistent thirst were more often younger and male and had more HF symptoms. Higher body mass index and serum urea also increased the risk of persistent thirst. Conclusions: Patients with HF who were thirsty at the 1-month follow-up were more often also thirsty at subsequent visits. Assessment of thirst is warranted in clinical practice because one-fifth of patients suffer from persistent thirst.

- The aim of our study is to investigate the effect of spironolactone on 30-day outcomes in patients with acute heart failure (AHF) and the association between treatment and outcomes stratified by biomarkers. We conducted a secondary analysis of the biomarker substudy of the multicenter COACH (Co-ordinating Study Evaluating Outcomes of Advising and Counseling in Heart Failure) trial involving 534 AHF patients for 30-day mortality and HF rehospitalizations. Spironolactone therapy was initiated and terminated at the discretion of the treating physician; 30-day outcomes were compared between patients who were treated with spironolactone and those who were not. Outcomes with spironolactone therapy. were explored based on N-terminal pro-B-type natriuretic peptide, ST2, galectin-3, and creatinine levels. Spironolactone was prescribed to 297 (55.6%) patients at discharge (158 new and 139 continued). There were 19 deaths and 30 HF rehospitalizations among 46 patients by 30 days. Patients discharged on spironolactone had significantly less 30-day event (hazard ratio 0.538, p = 0.039) after adjustment for multiple risk factors. Initiation of spironolactone in patients who were not on spironolactone before admission was associated with a significant reduction in event rate (hazard ratio 0.362, p = 0.027). The survival benefit of spironolactone was more prominent in patient groups with elevations of creatinine, N-terminal pro B-type natriuretic peptide, ST2, or galectin-3. In conclusion, AHF patients who received spironolactone during hospitalization had significantly fewer 30-day mortality and HF rehospitalizations, especially in high-risk patients.

- AimTraditionally, risk stratification in heart failure (HF) emphasizes assessment of high risk. We aimed to determine if biomarkers could identify patients with HF at low risk for death or HF rehospitalization. Methods and resultsThis analysis was a substudy of The Coordinating Study Evaluating Outcomes of Advising and Counselling in Heart Failure (COACH) trial. Enrolment of HF patients occurred before discharge. We defined low risk as the absence of death and/or HF rehospitalizations at 180days. We tested a diverse group of 29 biomarkers on top of a clinical risk model, with and without N-terminal pro-B-type natriuretic peptide (NT-proBNP), and defined the low risk biomarker cut-off at the 10th percentile associated with high positive predictive value. The best performing biomarkers together with NT-proBNP and cardiac troponin I (cTnI) were re-evaluated in a validation cohort of 285 HF patients. Of 592 eligible COACH patients, the mean (SD) age was 71 (+/- 11) years and median (IQR) NT-proBNP was 2521 (1301-5634) pg/mL. Logistic regression analysis showed that only galectin-3, fully adjusted, was significantly associated with the absence of events at 180days (OR 8.1, 95% confidence interval 1.06-50.0, P=0.039). Galectin-3, showed incremental value when added to the clinical risk model without NT-proBNP (increase in area under the curve from 0.712 to 0.745, P=0.04). However, no biomarker showed significant improvement by net reclassification improvement on top of the clinical risk model, with or without NT-proBNP. We confirmed our results regarding galectin-3, NT-proBNP, and cTnI in the independent validation cohort. Conclusion We describe the value of various biomarkers to define low risk, and demonstrate that galectin-3 identifies HF patients at (very) low risk for 30-day and 180-day mortality and HF rehospitalizations after an episode of acute HF. Such patients might be safely discharged.
