BACKGROUND: Percutaneous mitral valve edge-to-edge repair (pMVR) with a MitraClip is beneficial for the clinical symptoms of patients irrespective of the ejection fraction (EF). Nevertheless, the consequences on hemodynamics are poorly understood. Therefore, we used data from noninvasive pressure-volume loops to investigate the left ventricular (LV) remodeling of patients after pMVR dependent on their baseline EF. METHODS AND RESULTS: In 130 patients with successful pMVR, the end-diastolic pressure-volume relationship (EDPVR) and end-systolic pressure-volume relationship were estimated noninvasively from echocardiographic data...

Renin-angiotensin-aldosterone system (RAAS) and sympathetic nervous system play crucial roles in heart failure with reduced ejection fraction (HFrEF). Clinical trials provide strong evidence of prognostic benefits for combination therapy with angiotensin-converting enzyme inhibitor (ACEI) and β-blocker in the treatment of HFrEF. Angiotensin receptor blocker (ARB) is not superior to ACEI in improving mortality and an alternative for patients who are intolerant to ACEI. Prognostic evidence for triple therapy which combined angiotensin receptor blocker (ARB) and ACEI in addition to β-blocker therapy, is still controversial in HFrEF...

The relationship between glycemic control and outcome in patients with heart failure (HF) remains contentious. A recent study showed that patients with HF with mid-range ejection fraction (HFmrEF) more frequently had comorbid diabetes relative to other patients. Herein, we examined the association between glycosylated hemoglobin (HbA1c) and in-hospital mortality in acute HF patients with reduced, mid-range, and preserved EF. A multicenter retrospective study was conducted on 5205 consecutive patients with acute HF...

Importance: Heart failure with preserved ejection fraction (HFpEF) is highly prevalent, yet there are no specific therapies, possibly due to phenotypic heterogeneity. The development of pulmonary hypertension (PH) in patients with HFpEF is considered a high-risk phenotype in need of targeted therapies, but there have been limited hemodynamic and outcomes data. Objective: To identify the hemodynamic characteristics and outcomes of PH-HFpEF. Design, Setting, and Participants: Cohort study of participants who had a right heart catheterization from January 2005 to September 2012 (median [interquartile range] follow-up time, 1578 [554-2513] days) were analyzed...

OBJECTIVES: Reinforcements for the pulmonary autograft (PA) in the Ross operation have been introduced to avoid the drawback of conduit expansion and failure. With the aid of an in silico simulation, the biomechanical boundaries applied to a healthy PA during the operation were studied to tailor the best implant technique to prevent reoperation. METHODS: Follow-up echocardiograms of 66 Ross procedures were reviewed. Changes in the dimensions and geometry of reinforced and non-reinforced PAs were evaluated...

RATIONALE: Hypereosinophilic syndrome (HES) is a rare disease characterized by hypereosinophilia and its ensuing organ damage. Cardiac involvement is divided into 3 chronological stages: an acute necrotic stage; a thrombus formation stage; and a fibrotic stage. Infiltration of the myocardium by eosinophilic cells followed by endomyocardial fibrosis is known as "Loeffler endocarditis." PATIENT CONCERNS: We report a case of a 60-year-old man diagnosed with left-sided restrictive cardiomyopathy...

BACKGROUND: Worsening renal function (WRF) is associated with adverse outcomes in patients with heart failure. We investigated the predictors and prognostic value of WRF during admission, in patients with preserved ejection fraction (HFpEF) versus those with reduced ejection fraction (HFrEF). METHODS AND RESULTS: A total of 5625 patients were enrolled in the KorAHF (Korean Acute Heart Failure) registry. WRF was defined as an absolute increase in creatinine of ≥0...

BACKGROUND: Lung ultrasound (LUS) can be used to assess pulmonary congestion by imaging B-lines ('comets') for patients with acute heart failure (AHF). OBJECTIVES: Investigate relationship of B-lines, plasma concentrations of B-type natriuretic peptide (BNP), and echocardiographic left ventricular (LV) function measured at admission and discharge and their relationship to prognosis for AHF with preserved (HFpEF) or reduced (HFrEF) LV ejection fraction. METHODS: Patients with AHF had the above tests done at admission and discharge...

Cardio-oncology is an emerging discipline focused predominantly on the detection and management of cancer treatment-induced cardiac dysfunction (cardiotoxicity), which predisposes to development of overt heart failure or coronary artery disease. The direct adverse consequences, as well as those secondary to anticancer therapeutics, extend beyond the heart, however, to affect the entire cardiovascular-skeletal muscle axis (ie, whole-organism cardiovascular toxicity). The global nature of impairment creates a strong rationale for treatment strategies that augment or preserve global cardiovascular reserve capacity...

Utilization of a left ventricular assist device (LVAD) as a bridge to myocardial recovery is an established therapy for acute systolic heart failure. However, device removal can present a technical challenge with no clear consensus on preferred method. In this case report, we describe a complex patient who underwent successful explantation of an LVAD using an intraoperatively constructed apical plug. This method utilizes inexpensive and easily accessible materials, minimizes ventricular distortion during device removal, and preserves the ventricular sewing ring for future reimplantation...

BACKGROUND: The prognostic role of heart failure with preserved ejection fraction (HFpEF) remains unclear. This study aimed to assess HFpEF prognostic value after cardiothoracic surgery, adjusting for European System for Cardiac Operative Risk (EuroSCORE II) criteria. METHODS: Patients with left ventricular ejection fraction (LVEF) ≥ 50% undergoing cardiothoracic surgery between 2012 and 2016 were included. Patients with HFpEF were compared to control patients with LVEF ≥ 50%...

OBJECTIVES: A novel paradigm of diastolic left ventricular (LV) dysfunction proposes involvement of the cardiac microvasculature. Vitamin K dependent matrix Gla protein (MGP) plays a role in preserving microcirculatory integrity. We hypothesized that LV filling pressure-a measure of diastolic LV dysfunction-increases with higher plasma level of inactive desphospho-uncarboxylated MGP (dp-ucMGP). We also studied the distribution of active and inactive MGP in human myocardium. METHODS: We measured echocardiographic diastolic LV function and plasma dp-ucMGP (ELISA) in 668 Flemish and for replication in 386 Swiss...

Physiologically, leptin concentration is controlled by circadian rhythm. However, in critically ill patients, circadian rhythm is disrupted. Thus we hypothesized that circadian leptin concentration changes are not preserved in critically ill patients. Ten consecutive critically ill heart failure patients with the clinical indication for mechanical ventilation and sedation were included into our study. Plasma leptin concentration was measured every 4 h during the first day (0-24 h) and during the third day (48-72 h) after admission...

OBJECTIVES: This study sought to characterize the functional and prognostic significance of oxygen uptake (VO2 ) kinetics following peak exercise in individuals with heart failure (HF). BACKGROUND: It is unknown to what extent patterns of VO2 recovery following exercise reflect circulatory response during exercise in HF with preserved ejection fraction (HFpEF) and HF with reduced ejection fraction (HFrEF). METHODS: We investigated patients (30 HFpEF, 20 HFrEF, and 22 control subjects) who underwent cardiopulmonary exercise testing with invasive hemodynamic monitoring and a second distinct HF cohort (n = 106) who underwent noninvasive cardiopulmonary exercise testing with assessment of long-term outcomes...

Obesity-related heart failure with a preserved ejection fraction (HFpEF) is an important phenotype prevalent in the community, especially in people with metabolic disorders (e.g., dyslipidemia, diabetes). These individuals exhibit a marked expansion of plasma volume, but ventricular distensibility is limited, most likely as a result of cardiac microvascular rarefaction acting in concert with myocardial and pericardial fibrosis. Consequently, the increase in plasma volume causes a disproportionate increase in cardiac filling pressures, leading to heart failure, even though systolic ejection is not impaired...

Patients with heart failure and preserved ejection fraction (HFpEF) tend to be older and have a high co-morbidity burden. The impact of co-morbid conditions and sociodemographic risk factors on outcomes in these patients has not been quantified. We evaluated 445 consecutive outpatients with HFpEF, defined as established diagnosis of heart failure (HF) with left ventricular ejection fraction at presentation >40% and no previous left ventricular ejection fraction ≤40%. Patients with specific cardiomyopathies, congenital heart disease, primary right-sided disease, valvular disease, or previous advanced HF therapies were excluded...

BACKGROUND: Heart failure (HF) is associated with cognitive impairment. However, we know little about the time course of cognitive change after HF diagnosis, the importance of comorbid atrial fibrillation, or the role of ejection fraction. We sought to determine the associations of incident HF with rates of cognitive decline and whether these differed by atrial fibrillation status or reduced versus preserved ejection fraction. METHODS AND RESULTS: Participants were 4864 men and women aged ≥65 years without a history of HF and free of clinical stroke in the CHS (Cardiovascular Health Study)-a community-based prospective cohort study in the United States, with cognition assessed annually from 1989/1990 through 1998/1999...

The coexistence of type 2 diabetes mellitus (T2DM) and heart failure (HF), either with reduced (HFrEF) or preserved ejection fraction (HFpEF), is frequent (30-40% of patients) and associated with a higher risk of HF hospitalization, all-cause and cardiovascular (CV) mortality. The most important causes of HF in T2DM are coronary artery disease, arterial hypertension and a direct detrimental effect of T2DM on the myocardium. T2DM is often unrecognized in HF patients, and vice versa, which emphasizes the importance of an active search for both disorders in the clinical practice...
