The results showed that the serum concentrations of 17 proteins (e.g. angiogenin, activin A and artemin) differed considerably between HFPEF and non-HFPEF patients (hypertensive patients and healthy controls), while a protein expression pattern distinct from that in non-HFPEF patients was associated with HFPEF patients.
This pilot study indicates that the aforementioned 17 potential biomarkers, such as angiogenin, may hold great promise for both diagnosis and prognosis assessment of HFPEF.
To explore the association between ACE gene insertion/deletion (I/D) polymorphism with left ventricular hypertrophy (LVH) in patients with hypertension who have developed heart failure with preserved ejection fraction (HFpEF).
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.
We then sought to investigate the effects of chronic macitentan, a dual ET-A/ET-B receptor antagonist, on cardiac structure and function in a murine model of HFpEF induced by chronic aldosterone infusion.
By logistic regression analysis age, female sex, pulmonary disease, renal dysfunction, loop diuretics and aldosterone receptor antagonist were negatively associated with prognosis in HFpEF, whereas angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (ACEi/ARBs) and Statins were positive prognostic factors.
The use of mineralocorticoid receptor antagonists (MRAs) has demonstrated major benefits in heart failure with reduced ejection fraction (HFrEF), results with challenging inconsistencies in heart failure with preserved ejection fraction (HFpEF), and 'neutral' preliminary results in acute heart failure.
A total of 176 hypertensive patients with a diagnosis of HFpEF were divided to cases with LVH and controls without. rs4343 and rs4291 of angiotensin-converting enzyme (ACE) and rs5186 of angiotensin receptor type 1 were genotyped using PCR-RFLP method.
Clinical trials using beta blockers and angiotensin converting enzyme inhibitors, cardiac-targeting drugs that reduce mortality in heart failure with reduced ejection fraction (HFrEF), have had disappointing results in HFpEF patients.
Large randomized controlled trials (RCTs) did not show clear mortality benefit of renin-angiotensin system (RAS) inhibitors (angiotensin-converting enzyme inhibitors or angiotensin receptor blockers) in HFpEF.
Studies with angiotensin-converting enzyme inhibitors (ACE-Is) and angiotensin receptor blockers (ARBs) in patients with heart failure with preserved ejection fraction (HFpEF) have yielded inconsistent results.
We investigated the role of three renin-angiotensin-aldosterone system (RAAS) gene polymorphisms in the development of LVH in hypertensive patients with a diagnosis of HFpEF.
Large randomized controlled trials (RCTs) did not show clear mortality benefit of renin-angiotensin system (RAS) inhibitors (angiotensin-converting enzyme inhibitors or angiotensin receptor blockers) in HFpEF.
Of 1174 patients identified (537 [46%] female; median [interquartile range {IQR}] age, 56 [44-66] years), 250 were "at risk" for HFpEF given elevated brain-type natriuretic peptide (BNP) level; 160 had HFpEF by documented clinical diagnosis, and 745 did not have HFpEF.
In the near future, trials should target HFrEF patients using exclusion criteria sourced from landmark trials (e.g. severe renal impairment), select more homogeneous HFpEF populations (e.g. with elevated BNP and structural abnormalities on echocardiography), and determine which patients are likely to benefit from MRAs (e.g. according to prespecified biomarkers).
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.
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.
IGF-1 was associated with outcomes in HFrEF, hazard ratio per natural logarithmic increase in IGF-1 SD score 0.51 (95% confidence interval 0.32-0.82, P = .005), but not significantly in HFpEF.
Caveolin-1 (Cav1)<sup>-/-</sup> mice display impaired development of left ventricular pressure and increased left ventricular wall thickness but no dilated ventricle; these are typical findings in patients with heart failure with preserved ejection fraction (HfpEF).
The Diastolic Heart Failure Anakinra Response Trial 2 (D-HART2) is a phase 2, 2:1 randomized, double-blind, placebo-controlled clinical trial that will test the hypothesis that IL-1 blockade with anakinra (recombinant human IL-1 receptor antagonist) improves (1) cardiorespiratory fitness, (2) objective evidence of diastolic dysfunction, and (3) elevated inflammation in patients with HFpEF (http://www.ClinicalTrials.gov NCT02173548).
