Filter by:Heart failure with preserved ejection fraction (HPEF, defined as LVEF ≥50%) represents 50% of hospital admissions for heart failure. Although its morbi-mortality is similar to that of heart failure with reduced ejection fraction (HFPEF), it remains an unknown disease with limited data especially from an etiological point of view. The underlying causes are imperfectly understood, and more than half of the patients have HPEF labeled "idiopathic." A non-hierarchical clustering study of HPEF patients led to the identification of a subgroup of patients (25%) with a predominant coronary vascular phenotype (i.e., a history of coronary stenosis with or without the need for revascularization). In these patients, vascular endothelial dysfunction would play a central role in the development and progression of heart failure.One of the mechanisms leading to HPEF could be a decrease in the bioavailability of nitric oxide (NO) involved in the relaxation of the cardiac muscle. As the mechanism of action of NO is pleiotropic, a decrease in NO bioavailability could also be observed at the peripheral level, favoring in the long term the development of unfavorable vascular remodeling, for example in the small digital or retinal arteries.Some HPEF patients could thus be distinguished from others by their predominant "vascular" profile. The link between HPEF and endothelial dysfunction has been suspected but never clearly demonstrated. Ultra-high frequency ultrasound is an innovative technology to estimate the remodeling of small distal arteries in a non-invasive way. The investigators propose to use this imaging on digital arteries in HPEF patients and to study the association with known coronary macrovascular damage.The remodeling parameters will be measured and compared in patients with HPEF with or without identified macrovascular coronary disease.This characterization of arterial remodeling on the digital arteries could be a powerful tool for non-invasive screening in the identification of a subgroup of HPEF that is still considered idiopathic.
This study is to evaluate the safety and effectiveness of the Corheart 6 Ventricular Assist System (Corheart 6 VAS) when used for the treatment of advanced refractory heart failure.
STRONG-HF showed that rapid up-titration of renin-angiotensin inhibitor (RASI), beta-blocker, and mineralocorticoid receptor antagonist (MRA) to full optimal doses within 2 weeks post-discharge from a hospital admission for acute heart failure (AHF), using frequent safety assessments, significantly reduced the 180-day risk of HF readmission or death and significantly increased 90-day quality of life regardless of left ventricular ejection fraction (LVEF). Recent evidence also suggests that initiation of angiotensin-receptor neprilysin inhibitor (ARNI) and SGLT-2 inhibitors close to the time of discharge regardless of LVEF, and iron supplementation where indicated, improve patient prognosis. In this prospective registry of patients not treated with optimal doses of oral HF medications being discharged from an admission for AHF, ROBUST-HF, data will be collected describing their post-discharge care including the management of their oral HF medications and frequency and content of post-discharge assessments and clinical outcomes through 6 months post discharge.
The objective is to assess the feasibility and safety of the Supira System in providing temporary cardiovascular hemodynamic support in patients undergoing HRPCI.
The goal of the trial is to study the effects of lavender essential oil on sleep quality, anxiety, and fatigue in patients with chronic heart failure. The main questions it may answer are 1. effects of lavender essential oil on sleep quality 2. effects of lavender essential oil on anxiety 3. effects of lavender essential oil on fatigue Patients will be randomly divided into experimental and control groups, the control group will inhale essential coconut oil, and the experimental group will inhale lavender essential oil for four weeks. At baseline, on the 7th day, and 28th day, the sleep quality, anxiety, and fatigue will be evaluated.
In the MAPLE-CHF trial, patients will be screened for HF risk factors using electronic medical records of participating family physicians to identify patients with potentially undiagnosed HF. Participants will then undergo a diagnostic evaluation using a blood sample for a hormone specific to the heart, the natriuretic peptide or NT-proBNP; if elevated, a portable cardiac ultrasound (ECHO) with artificial intelligence (AI) interpretation will be done; both NT-proBNP and ECHO are required for diagnosis in patients with signs and symptoms suggestive of HF. This screening ECHO coupled with AI reading from Us2.ai provides a fast, reliable, and inexpensive report, which is particularly important in our context, where waiting lists for such examinations can reach up to one year.
The purpose of the Aim 3 study is to conduct a pilot randomized controlled trial to assess feasibility and preliminary effects of the TPA4You intervention.
Background: Heart failure is the severe and terminal stage of various heart diseases, which is characterized by high morbidity, mortality and readmission. There are few studies on the relationship between XinKang-I(XK-I) and chronic heart failure. Objective: To explore the relationship between XK-I and chronic heart failure. Methods/design: The trial is a single-center, single-blind, randomized study (1:1). It will recruit 110 patients with chronic heart failure who syndrome of qi deficiency yang deficiency and blood stasis. The intervention group will receive not only Western medicine, but also XK-I. The primary end points will be the changes in oxygen consumption volume of anaerobic threshold (VO2AT), maximum oxygen volume uptake (VO2max), and 6-minute walking distance after 8 weeks of treatment. Both groups will receive 8 weeks of treatment. Ethics and dissemination: Ethical approval was granted by Ethics Committee of Dongguan TCM Hospital. Results will be disseminated via peer-reviewed publications and presentations at international conferences.
