Beneficial association of β-blocker therapy on recovery from severe acute heart failure treatment: Data from the Survival of Patients with Acute Heart Failure in Need of Intravenous Inotropic Support trial

OBJECTIVES: Beta-blocker therapy is recommended for most patients with chronic heart failure, although such therapy may be discontinued or reduced during hospitalizations. The aim is to determine whether β-blocker use at study entry and/or at discharge has an impact on 31-and 180-day survival. DESIGN: Survival of Patients With Acute Heart Failure in Need of Intravenous Inotropic Support study was designed as a randomized, double-blind, active-controlled, multi-center study. SETTING: Multinational. PATIENTS: A total of 1,327 critically ill patients hospitalized with low-output heart failure in need of inotropic therapy. INTERVENTION: Levosimendan versus dobutamine. MEASUREMENTS: All-cause mortality at 31 and 180 days in patients who survived initial hospitalization with/without β-blocker use at entry and/or at discharge. RESULTS: Patients on β-blockers at entry and at discharge had significantly lower 31-day (p <.0001) and 180-day (p <.0001) mortality compared to patients without β-blockers use at both time points. The association was robust when adjusted for age and co-morbidities (p =.006 at 31 days; p =.003 at 180 days). CONCLUSIONS: Those results strongly suggest, in severe acutely decompensated heart failure patients, admitted on β-blockers, to continue on them at discharge.

Safety, Tolerability and efficacy of Rapid Optimization, helped by NT-proBNP and GDF-15, of Heart Failure therapies (STRONG-HF): rationale and design for a multicentre, randomized, parallel-group study

Aims: Patients admitted for acute heart failure (HF) are at high risk of readmission and death, especially in the 90 days following discharge. We aimed to assess the safety and efficacy of early optimization of oral HF therapy with beta-blockers (BB), angiotensin-converting enzyme inhibitors (ACEi) or angiotensin receptor blockers (ARB) or angiotensin receptor–neprilysin inhibitors (ARNi), and mineralocorticoid receptor antagonists (MRA) on 90-day clinical outcomes in patients admitted for acute HF. Methods: In a multicentre, randomized, open-label, parallel-group study, a total of 900 patients will be randomized in a 1:1 ratio to either ‘usual care’ or ‘high-intensity care’. Patients enrolled in the usual care arm will be discharged and managed according to usual clinical practice at the site. In the high-intensity care arm, doses of oral HF medications – including a BB, ACEi or ARB, and MRA – will be up-titrated to 50% of recommended doses before discharge and to 100% of recommended doses within 2 weeks of discharge. Up-titration will be delayed if the patients develop worsening. symptoms and signs of congestion, hyperkalaemia, hypotension, bradycardia, worsening of renal function or significant increase in N-terminal pro-B-type natriuretic peptide between visits. The primary endpoint is 90-day all-cause mortality or HF readmission. Conclusions: STRONG-HF is the first study to assess whether rapid up-titration of evidence-based guideline-recommended therapies with close follow-up in a large cohort of patients discharged from an acute HF admission is safe and can affect adverse outcomes during the first 90 days after discharge.

Imbalanced Angiogenesis in Peripartum Cardiomyopathy - Diagnostic Value of Placenta Growth Factor

BACKGROUND: Concentrations of the anti-angiogenic factor soluble fms-like tyrosine kinase-1 (sFlt-1) are altered in peripartum cardiomyopathy (PPCM). In this study we investigated changes in the angiogenesis balance in PPCM.Methods and Results:Plasma concentrations of sFlt-1 and the pro-angiogenic placenta growth factor (PlGF) were determined in patients with PPCM during the post-partum phase (n=83), in healthy women at delivery (n=30), and in patients with acute heart failure (AHF; n=65). Women with cardiac failure prepartum or associated with any form of hypertension, including pre-eclampsia, were excluded. Compared with non-pregnant women, in women with AHF and PPCM, median PlGF concentrations were greater (19 [IQR 16-22] and 98 [IQR 78-126] ng/mL, respectively; P0.94. Median plasma concentrations of the anti-angiogenic factor relaxin-2 were lower in PPCM and AHF (0.3 [IQR 0.3-1.7] and 0.3 [IQR 0.3-1] ng/mL, respectively) compared with normal deliveries (1,807 [IQR 1,101-4,050] ng/mL; P<0.001). CONCLUSIONS: Plasma of PPCM patients shows imbalanced angiogenesis. High PlGF and/or low sFlt-1/PlGF may be used to diagnose PPCM
