Background: Pulmonary hypertension due to left ventricular heart failure with preserved ejection fraction (PH-HFpEF) is an increasingly medical problem. The aim of the study was to evaluate the clinical efficacy of fasudil on PH-HFpEF elderly patients and to figure out the subtype of PH-HFpEF which may be the therapeutic object of fasudil. Method: 58 PH-HFpEF elderly patients were enrolled. Patients were diagnosed with passive pulmonary hypertension (PPH) or reactive pulmonary hypertension (RPH) by right heart catheterization and all receiving Rho kinase inhibitor fasudil for 2 weeks...

The article focuses on current aspects of epidemiology, clinical picture, and diagnostics of patients with chronic heart failure (CHF) associated with preserved left ventricular (LV) systolic function. Heart failure with preserved LV ejection fraction (HFpEF) is shown to be prevalent in a population that accounts for more than a half of all CHF cases. The group at risk for HFpEF consists primarily of older women with arterial hypertension, type 2 diabetes mellitus, obesity, and atrial fibrillation. The article presents algorithms for diagnosis of HFpEF based on classic and tissue Doppler echocardiography and measurement of natriuretic peptides...

Chronic kidney disease is observed in most patients with CHF with preserved ejection fraction (HFpEF) and presents a major risk factor facilitating development and progression of LV diastolic dysfunction. The review focused on the effect of chronic kidney disease on intracellular signaling pathways affecting stiffness and diastolic relaxation of cardiomyocytes in response to inflammation and endothelial dysfunction of coronary capillaries, excessive sympathetic activation, and dysregulation of natriuretic peptides, which directly participate in the development of CHF...

AIM: To examine the association of polymorphism 4a/4b and 4b/4b in endothelial nitric oxide synthase gene (eNOS) with levels of natriuretic peptide type-C, endothelin-1 and vasoregulative endothelial function in patients with chronic heart failure (CHF) depending on the ejection fraction of the left ventricle. MATERIALS AND METHODS: The study has included 280 patients with CHF of ischemic etiology and 60 somatically healthy individuals. A comprehensive assessment of the markers of the vascular endothelium function was carried out for all patients (endothelial function coefficient, natriuretic peptide type-C, endothelin-1) in association of polymorphism 4a/4b and 4b/4b gene of eNOS...

The review is devoted to pharmacotherapy of chronic heart failure (CHF) with preserved left ventricular ejection fraction. In this review we discuss data of meta-analyzes of randomized clinical trials and observational studies, as well as the indications for use of inhibitors of the renin-angiotensin-aldosterone system, β-blockers, and antagonists of mineralocorticoid receptors in these patients in current clinical guidelines. New approaches to therapy of CHF from the perspective of influence on myocardial fibrosis are considered in this review...

The aim of the study was comparison of contractile function of isolated hearts of rats with doxorubicin-induced myocardial injury which were tentatively divided according to the level of ejection fraction determined by echocardiography in vivo. After 4 weeks of doxorubicin administration (2 mg/kg subcutaneously once a week) about half of animals had normal (86±1 %) and the other half reduced (61±4 %) ejection fraction. The first group was defined as diastolic heart failure (DHF) and the other as systolic (SHF)...

AIM: To determine the effect of right ventricular myocardial contractility on the response to cardiac resynchronization therapy (CRT). MATERIALS AND METHODS: The study included 80 patients (49 men, mean age 54±10.5) diagnosed with dilated cardiomyopathy, complete left bundle branch block, and the QRS complex width 146 to 240 ms (183±32 ms). Heart failure was NYHA FC III, ejection fraction (EF) - 30.1±3.8 %, 6‑min walk test - 290.5±64.3 m, and end-diastolic volume (EDV) - 220...

BACKGROUND: Heart rate (HR) and systolic blood pressure (SBP) are prognostic markers in heart failure with reduced ejection fraction (HFrEF). Their combination in rate-pressure product (RPP) as well as their role in heart failure with preserved ejection fraction (HFpEF) remains unclear. METHODS: We performed an analysis of ASCEND-HF (clinicaltrials.gov; NCT00476852), which studied 7141 patients with acute HF. HFpEF was defined as left ventricular ejection fraction (LVEF) ≥40%...

INTRODUCTION: A new drug with prognostic impact on heart failure, sacubitril/valsartan, has been introduced in current guidelines. However, randomized trial results can be compromised by lack of representativeness. We aimed to assess the representativeness of the PARADIGM-HF trial in a real-world population of patients with heart failure. METHODS: We reviewed the records of 196 outpatients followed in a heart failure clinic between January 2013 and December 2014...

OBJECTIVES: This study sought to identify whether impaired global longitudinal strain (GLS), diastolic dysfunction (DD), or left atrial enlargement (LAE) should be added to stage B heart failure (SBHF) criteria in asymptomatic patients with type 2 diabetes mellitus. BACKGROUND: SBHF is a precursor to clinical heart failure (HF), and its recognition justifies initiation of cardioprotective therapy. However, original definitions of SBHF were based on LV hypertrophy and impaired ejection fraction...

REVIEW
Milton Packer
Epicardial adipose tissue has unique properties that distinguish it from other depots of visceral fat. Rather than having distinct boundaries, the epicardium shares an unobstructed microcirculation with the underlying myocardium, and in healthy conditions, produces cytokines that nourish the heart. However, in chronic inflammatory disorders (especially those leading to heart failure with preserved ejection fraction), the epicardium becomes a site of deranged adipogenesis, leading to the secretion of proinflammatory adipokines that can cause atrial and ventricular fibrosis...

OBJECTIVE: Acute heart failure (AHF) is one of the most commonly seen clinical cases, with a high rate of re-hospitalization and mortality. AHF can be divided into two categories based on the systolic function of the left ventricle, which are heart failure with reduced ejection fraction (HFREF) and heart failure with preserved ejection fraction (HFPEF). Pathogenesis and treatment of the two are quite different. In this article we attempted to explore the value of combined use of clinical and laboratory indicators in the differential diagnosis of AHFREF and AHFPEF...

REVIEW
Hao-Min Cheng, Jiun-Jr Wang, Chen-Huan Chen
Vascular calcification is heterogeneous and triggered by multiple mechanisms. It has been implicated in the development of heart failure with preserved ejection fraction (HFpEF) and cognitive function impairment. Understanding the pathophysiology of vascular calcification may help us improve the management of HFpEF, atherosclerosis, accelerated arterial stiffness, hypertension, and cognitive dysfunction. Currently, there are no effective strategies for treating accelerated arterial stiffness. This may indicate that once arterial stiffness or vascular calcification has developed, it may be less likely to stop the ongoing pathophysiology...

<u>Rationale:</u> Increased titin-dependent cardiomyocyte tension is a hallmark of heart failure with preserved ejection fraction (HFpEF) associated with type-2 diabetes mellitus (T2DM). However, the insulin-related signaling pathways that modify titin-based cardiomyocyte tension, thereby contributing to modulation of diastolic function, are largely unknown. <u>Objective:</u> We aimed to determine how impaired insulin signaling affects titin expression and phosphorylation and thus increases passive cardiomyocyte tension, and whether metformin or neuregulin-1 can correct disturbed titin modifications and increased titin-based stiffness...

Patients with thoracic aortic aneurysm (TAA) are mostly asymptomatic and TAA is rarely related to heart failure (HF). We report the case of an 80-year-old female patient, with type A TAA without dissection, with right pulmonary artery and left atrium compression, who presented with HF, preserved ejection fraction and acute pulmonary edema.

REVIEW
Biykem Bozkurt, Shaden Khalaf
Heart failure is an important cause of morbidity and mortality in women, and they tend to develop it at an older age compared to men. Heart failure with preserved ejection fraction is more common in women than in men and accounts for at least half the cases of heart failure in women. When comparing men and women who have heart failure and a low left ventricular ejection fraction, the women are more symptomatic and have a similarly poor outcome. Overall recommendations for guideline-directed medical therapies show no differences in treatment approaches between men and women...

BACKGROUND: Heart failure (HF) is associated with a high rate of readmissions within 30 days post-discharge and in the following year, especially in frail elderly patients. Biomarker data are scarce in this high-risk population. This study assessed the value of early post-discharge circulating levels of ST2, NT-proBNP, CA125, and hs-TnI for predicting 30-day and 1-year outcomes in comorbid frail elderly patients with HF with mainly preserved ejection fraction (HFpEF). METHODS: Blood samples were obtained at the first visit shortly after discharge (4...

We sought to assess the inheritance of left ventricular (LV) function using speckle-tracking echocardiography and the impact of hypertension on modifying the genetically determined pattern of contraction in a population of twins. We recruited 92 Caucasian twin pairs, including 74 hypertensive (HTN) siblings. Beyond standard echocardiographic protocol, a speckle-tracking analysis was performed, including global longitudinal strain (GLS). Systolic function, as assessed by ejection fraction, showed moderate heritability (61%); however, GLS showed higher and dominant heritability (75%)...

REVIEW
Milton Packer
The injection of mesenchymal stem cells into the injured myocardium to induce cardiac regeneration has yielded disappointing results, conceivably because cells with cardioreparative potential must be supplied for long periods of time to produce a salutary effect. Accordingly, investigators have devised ways of directing such cells to the heart on an ongoing basis: by enhancing the action of endogenous peptides that function as cardiac homing signals (eg, stromal cell-derived factor-1). Stromal cell-derived factor-1 is released during acute cardiac injury and heart failure, but it has a short half-life because of degradation by dipeptidyl peptidase-4...
