The aim of this work was to evaluate the short-term fractal index (α1 ) of heart rate variability (HRV) in chronic renal failure (CRF) patients by identifying the effects of orthostatism and hemodialysis (HD), and by evaluating the correlation between α1 and the mean RR interval from sinus beats (meanNN). HRV time series were derived from ECG data of 19 CRF patients and 20 age-matched healthy subjects obtained at supine and orthostatic positions (lasting 5 min each). Data from CRF patients were collected before and after HD...

AIMS: To assess the haemodynamic effects of organic vs. inorganic nitrate administration among patients with heart failure with preserved ejection fraction (HFpEF). METHODS AND RESULTS: We assessed carotid and aortic pressure-flow relations non-invasively before and after the administration of 0.4 mg of sublingual nitroglycerin (n = 26), and in a separate sub-study, in response to 12.9 mmoL of inorganic nitrate (n = 16). Nitroglycerin did not consistently reduce wave reflections arriving at the proximal aorta (change in real part of reflection coefficient, 1st harmonic: -0...

BACKGROUND: Several markers detected on the routine 12-lead ECG are associated with future heart failure events. We examined whether these markers are able to separate the risk of heart failure with reduced ejection fraction (HFrEF) from heart failure with preserved ejection fraction (HFpEF). METHODS AND RESULTS: We analyzed data of 6664 participants (53% female; mean age 62±10 years) from MESA (Multi-Ethnic Study of Atherosclerosis) who were free of cardiovascular disease at baseline (2000-2002)...

BACKGROUND: We investigated whether both echocardiography and blood examination parameters obtained before discharge are more closely associated with adverse events than those obtained upon admission in hospitalized heart failure (HF) patients. METHODS: We retrospectively selected 267 hospitalized HF patients who underwent comprehensive transthoracic echocardiography (TTE) within 2 days of admission (n=223) and/or within 7 days of discharge (n=157). Blood test results were also collected at the same time window...

Despite the growing number of patients with heart failure with preserved ejection fraction (HFpEF) and event rates comparable with many cancers, there remain no pharmacologic agents definitively proven to improve patient outcomes. Although phase II trials have intermittently yielded encouraging results, none have translated into successful achievement of a phase III primary end point. Thus, because of the urgent need to discover proven therapies, it is prudent to reevaluate our current approach to HFpEF drug development...

AIM: To investigate the clinical features of heart failure in extremely elderly patients. METHODS: We analyzed 1163 consecutive hospitalized heart failure patients. The patients were divided into an extremely elderly group (≥85 years-of-age, n = 88) and a non-extremely elderly group (<85 years-of-age, n = 1075). RESULTS: The extremely elderly group had higher rates of hypertension, chronic kidney disease, anemia, higher systolic blood pressure and lower body mass index, and lower use of β-blockers and anticoagulants compared with the non-extremely elderly group...

BACKGROUND: Women with signs and symptoms of ischemia, no obstructive coronary artery disease (CAD) and preserved left ventricular ejection fraction (EF) often have diastolic dysfunction and experience elevated rates of major adverse cardiac events (MACE), including heart failure (HF) hospitalization with preserved ejection fraction (HFpEF). We evaluated the predictive value of inflammatory biomarkers for long-term HF hospitalization and all-cause mortality in these women. METHODS: We performed a cross-sectional analysis to investigate the relationships between inflammatory biomarkers [serum interleukin-6 (IL-6), C-reactive protein (hs-CRP) and serum amyloid A (SAA)] and median of 6 years follow-up for all-cause mortality and HF hospitalization among women with signs and symptoms of ischemia, non-obstructive CAD and preserved EF...

Heart failure with preserved ejection fraction (HFpEF) is a condition with complex pathophysiology and clinical profile. No treatment has been proven to reduce mortality or reduce morbidity in a meaningful way. In the era of percutaneous cardiac interventions, a novel method of reducing left atrial pressure by creating an iatrogenic interatrial shunt has been introduced. We present a report of implantation of InterAtrial Shunt Device (IASD®) in three consecutive patients.

The new European Society of Cardiology guidelines reclassified heart failure according to left ventricular ejection fraction, recognizing patients with mid-range EF (mrEF; 40% to 49%) as a distinct group. We sought to investigate the clinical profile, in-hospital outcomes, and long-term mortality of ST-elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention who had mrEF. We conducted a retrospective study of 2,086 consecutive patients with STEMI between December 2007 and June 2016 who underwent primary percutaneous coronary intervention and had a comprehensive echocardiographic examination performed within 72 hours of hospital admission...

Improved survival following single ventricle palliation has led to a large population of patients with a Fontan circulation, many of whom will eventually develop Fontan failure. Many of these patients will require heart transplantation. However, more than half of these patients have Fontan failure despite preserved ventricular function. Increasing experience with ventricular assist devices (VAD) in children has paved the way for VAD support in those with failing univentricular circulation. Areas covered: The use of VADs to support the failing univentricular circulation is a relatively new concept...

Aims: Many patients with heart failure with preserved ejection fraction (HFpEF) develop post-capillary pulmonary hypertension (PH) due to increased left-sided filling pressures. However, a subset of patients develops combined post- and pre-capillary PH. We studied the value of echocardiographic right-sided characterization for the discrimination between pre- vs. post-capillary PH in HFpEF, using invasive haemodynamics as gold standard. Methods and results: 102 consecutive HFpEF patients with simultaneous right heart catheterization and echocardiography were identified...

BACKGROUND: Palliative care for advanced heart failure (HF) is generally recommended. However, few reports have focused on the particulars of treatment, or the clinical course of HF on a specific treatment regimen. OBJECTIVE: Palliation adequate to allow patients to avoid HF admission and die at home. METHODS: Patients from a veterans administration regional practice with multiple, recent hospital admissions were enrolled in community hospice programs...

According to the WHO, hypertension is one of the major causes of death worldwide. It leads to a number of severe complications. Diastolic heart failure, that is heart failure with preserved ejection fraction (HFPEF), is especially common. New, but simple, indices for the early detection of patients who have not yet developed complications or are in their early developmental stages are still searched for. AIM: The aim of this study is to examine the correlation between pulse wave velocity (PWV) and markers of diastolic heart failure (DHF) assessed in echocardiography in patients with hypertension and no symptoms of heart failure...

BACKGROUND: Natriuretic peptides or the blood urea nitrogen to creatinine ratio (BUN/creat) can identify high- vs low-risk renal impairment (RI) in patients with heart failure and reduced ejection fraction (HF-REF). However, the situation in HF patients with preserved ejection fraction (HF-PEF) and mid-range ejection fraction (HF-MREF) remains unclear. METHODS: We evaluated patients from the Spanish National Registry of Heart Failure (RICA) that were admitted to Internal Medicine units with acute decompensated HF...

In urban populations, worsening renal function (WRF) is well established in patients hospitalized with acute decompensated heart failure with preserved ejection fraction (HFpEF). However, the mechanisms for development of WRF in the setting of acute HF in HFpEF are unclear. In the present study, we sought to characterize conventional echocardiographic measures of right ventricular (RV) chamber size and function to determine whether RV dysfunction and/or adverse RV remodeling is related to WRF in patients with HFpEF...

OBJECTIVES: This study aimed to assess the hypothesis that mitral annular disjunction (MAD) is associated with abnormal annular dynamics due to decoupling of annular-ventricular function. BACKGROUND: MAD, defined as a separation between the atrial wall-mitral valve (MV) junction and left ventricular (LV) attachment, is a structural abnormality occurring in MV prolapse (MVP). Few data exist on the 3-dimensional (3D) geometry of MAD and its functional implication...
