Patients with HFpEF-PH were found to have increased ET1 in pulmonary veins (endothelin from the wedge; ET1W) compared to controls (2.3 ± 1.4 and 1.6 ± 0.9 pg/mL, respectively).
Whereas progress with respect to heart failure with preserved ejection fraction (HFpEF) is still slow, both ARNIs and SGLT2 inhibitors hold great promise for this condition as well, and large clinical trials are currently ongoing.
The aim of the ongoing MUSCAT-HF (It stands for Prospective Comparison of Luseogliflozin and Alpha-glucosidase on the Management of Diabetic Patients with Chronic Heart Failure and Preserved Ejection Fraction) trial is to evaluate the efficacy of luseogliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor, versus voglibose, an alpha-glucosidase inhibitor, using brain natriuretic peptide (BNP) as the index of therapeutic effect in T2DM patients with HFpEF.
The purpose of this study was to investigate the diagnostic and predictive value of galectin-3 and sST2 for use in patients who have heart failure with preserved ejection fraction (HFpEF).
This review deals with the impact of SGLT2 inhibitors on LV diastolic function in patients with DM and their current potential for prevention of the future development of HFpEF in such patients.
Reduced LA-GS but not LV functional systolic and diastolic parameters were associated with the pro-fibrotic ST2 marker, HF symptoms and outcome in HFpEF.
In addition, we review several classes of drugs currently in development for HFpEF such as neprilysin inhibitors, inorganic nitrates (nitrites), and soluble guanylate cyclase stimulators.
Median sST2 levels in male and female HFpEF patients were 36.7 ng/mL (range 30.9-49.2 ng/mL; reference range 4-31 ng/mL) and 30.8 ng/mL (range 25.3-39.3 ng/mL; reference range 2-21 ng/mL), respectively.
LCZ696, a combination drug of angiotensin II receptor blocker and neprilysin inhibitor, and the aldosterone receptor antagonist spironolactone are currently in clinical trial for treating HFpEF.
In addition, ATTR cardiac amyloidosis demonstrates a unique pathophysiology in contrast to other etiologies of HFpEF, which results in a characteristic phenotype that can raise suspicion for ATTRwt cardiac amyloid in the appropriate demographic.
Subjects with HFpEF display activation of the endothelin and adrenomedullin neurohormonal pathways, the magnitude of which is associated with pulmonary haemodynamic derangements, limitations in RV functional reserve, reduced cardiac output, and more profoundly impaired exercise capacity in HFpEF.
The α coefficient decreased from 1.35 ± 0.58%/mm Hg in control subjects and 1.1 ± 0.48%/mm Hg in patients with passive HFpEF to 0.62 ± 0.32%/mm Hg in exercise PH, 0.54 ± 0.27%/mm Hg in HFpEF with high exercise PVR, and 0.18 ± 0.16%/mm Hg in PAH.
In this review article, these most recent advances in the diagnosis and pharmacological management of HFrEF and HFpEF are highlighted, and set-backs as well as opportunities for future developments (e.g., tafamidis for the treatment of transthyretin amyloid cardiomyopathy) are discussed.
Patients with HFpEF+PVR with an exercise-induced decrease in Ees/Ea had lower pulmonary artery compliance, lower peak Vo<sub>2</sub>, and lower stroke volume than patients with HFpEF.
Impairment of SIRT3-mediated EC metabolism may lead to a disruption of EC/pericyte/cardiomyocyte communications and coronary microvascular rarefaction, which promotes cardiomyocyte hypoxia, Titin-based cardiomyocyte stiffness, and myocardial fibrosis, thus leading to a diastolic dysfunction and HFpEF.
After adjustment for clinical factors and NT-proBNP, galectin-3 was strongly correlated with an increased risk of the endpoint events in HFpEF patients, and the hazard ratio per 1 SD increase of the galectin-3 level was 2.33 (95%CI: 1.72-2.94, P=0.009).
Azilsartan has higher vascular affinity compared with other angiotensin II receptor blockers (ARBs), which were proven to have no beneficial effects on clinical outcomes in patients with HFpEF in earlier clinical trials.
Search II yielded 1869 studies, of which 51 studies on seven biomarkers were included in meta-analyses and 79 studies on 12 biomarkers in systematic review.Eleven biological markers differentiated women with diastolic dysfunction from controls, of which the following 10 markers differentiated women with pre-eclampsia from controls as well: C-reactive protein, HDL, insulin, fatty acid-binding protein 4, brain natriuretic peptide, N terminal pro brain natriuretic peptide, adrenomedullin, mid-region pro adrenomedullin, cardiac troponin I, and cancer antigen 125.Our study supports the hypothesis that HFpEF in women shares a common pathogenic background with pre-eclampsia.
Moreover, macitentan improved adverse cardiac remodeling, by reducing the stiffer cardiac collagen I and titin n2b expression in the left ventricle of mice with HFpEF.
LCZ696, a combination drug of angiotensin II receptor blocker and neprilysin inhibitor, and the aldosterone receptor antagonist spironolactone are currently in clinical trial for treating HFpEF.
In HFpEF, a decrease in peak VO<sub>2</sub> was associated with an increase in NT-proBNP (-0.726 mL/min/kg per doubling, 95% CI -1.100 to -0.353, P < .001), and a decrease in 6MWD was associated with an increase in growth differentiation factor-15 (-31.606 m per doubling, 95% CI -61.404 to -1.809, P = .038).
