Filter by:Heart failure (HF) accounts for 2% of National Health Service (NHS) expenditure, and 5% of emergency hospitalisations. Patients with HF with preserved ejection fraction (HFpEF) are older, have more comorbidities, have similarly poor or worse outcomes compared to patients with reduced ejection fraction (HFrEF), and currently lack an evidence base for treatment. The investigators hypothesise that outcomes of patients with HFpEF can be improved through optimised management and self-management of comorbidities, fluid status and lifestyle delivered in primary care in collaboration with specialists. The primary aim is to develop a programme of optimised management by improving understanding of needs and experiences of patients with HFpEF, clinical decision-making and management in primary care, and integrating research findings with patient and clinical expertise. The main objective for this work package is to identify patients with HFpEF in primary care and assess comorbidities and other factors, management, morbidity and mortality at one year. The methodology employed will be a longitudinal cohort study of 270 patients with HFpEF in primary care followed for 12 months.
The present study will randomize 50 symptomatic heart failure patients with severely reduced left ventricular ejection fraction (LVEF) and a true left bundle branch block to either direct HIS-pacing or biventricular pacing and follow them for at least six months. The outcome is how often it is possible to achieve HIS-pacing at implant and during follow-up and if HIS-pacing leads to differences in symptoms or measurable clinical parameters as compared to biventricular pacing.
Introduction: Heart failure is the leading cause of hospitalization among adults >65 years of age. Discharge from a heart failure hospitalization is followed by a 30 day readmission rate of ≈24%. Readmissions for heart failure are typically preceded by a gradual rise in ventricular filling pressures that begins days or weeks before any detectable changes in clinical status. Lung ultrasound (LUS) is a tool that is easily available at bedside and shows superior sensitivity for the detection of pulmonary congestion when compared with X ray or physical examination, even in the absence of symptoms. Pulmonary congestion assessed by LUS identifies a subgroup with worse prognosis and a higher rate of readmission and mortality. Whether the implementation of lung ultrasound in the follow up of heart failure patients may reduce the rate of readmissions is unknown. Objective: The aim of this study is to evaluate a protocol of lung ultrasound guided therapy to prevent readmissions in heart failure outpatients. Study design: the design of the investigator's study is a single center, single blinded, randomized controlled clinical trial. Eligibility criteria: patients older than 18 years of age, who have been hospitalized for an acute heart failure syndrome. Exclusion criteria are life expectancy of less than 6 months, a surgically correctable cause of heart failure or uninterpretable lung ultrasound. Eligible patients will be randomized into either "LUS-guided therapy group" or "control group" at hospital discharge. Follow-up visits will be scheduled at 15 days, 45 days, 3 months and 6 months after hospital discharge. LUS will be performed in all patients at hospital discharge and in every follow-up visit, but only in those allocated to the "LUS-guided therapy group" the information will be provided to the treating physician. In the "LUS-guided therapy group", a prespecified diuretic dose will be administered to patients depending on the degree of ultrasonographic pulmonary congestion: if congestive (3 or more B lines, in total) a high dose (80-120mg furosemide PO/day) will be prescribed; if no congestive (less than 3 B lines, in total) a low dose (up to 40mg PO/day) will be prescribed. Primary outcome will be the composite of hospital readmission + mortality. This study complies with the Declaration of Helsinki and the study protocol is being evaluated by the Ethic Committee of our institution.
This study is a randomized controlled trial that tests the effectiveness of a novel intervention called the Push-Pull-Hold program on improving self-care in patients with heart failure. This intervention was developed based on our previous quantitative and qualitative findings and existing psychological concepts. Results would inform current understanding of the intention-behavior link in self-care and inform future policy and intervention development to improve patient and caregiver outcomes.
Researchers are studying the effect of a single dose of oral myeloperoxidase on heart failure versus placebo.
The purpose of the ReLINQuish study is to characterize the relationship between subcutaneous impedance and hemodynamic measurements in patients with heart failure. Additionally, the relationship between changes in subcutaneous impedance and other physiologic parameters during acute decompensated HF events will be characterized.
Acute left heart failure (ALHF) is a sudden attack or deterioration of abnormal left heart function, which may impair myocardial contractility and increase cardiac loading, further result in decreased cardiac output, abrupt elevation of pulmonary and systemic circulation pressure, consequently trigger in acute pulmonary congestion, acute pulmonary edema and cardiac shock . Hypoxia and severe dyspnea may pose fatal threats for the patients suffered from ALHF should be alleviated as soon as possible, and thus oxygen therapy and ventilation support are regarded as important therapeutic measures for these patients. According to 2017 Chinese College of Emergency Physicians(CCEP) acute heart failure clinical guideline, invasive ventilation should be recommended to those patients whose symptoms still get worsening despite timely treatments. Intubation may increase the risks of infection and multiple organ failure, so timely extubation contributes to reduce the duration of mechanical ventilation and the rate of complications. But if extubation failure occurs, the patient often requires re-intubation that may induce the outset of complications, extend the length of stay and increase mortality. Heart failure proves to be high risk factor for extubation failure on the basis of previous studies. It is recommended to apply sequential non-invasive ventilation (NIV) if the patient receiving invasive ventilation for more than 24 hours and having high risk for extubation failure on the basis of 2017 American Thoracic Society(ATS) clinical guideline. It is worthy to note that NIV has many shortcomings, for example, it may induce dry oropharyngeal cavity, skin injury caused by mask oppression, gaseous distention, vomiting, respiratory aspiration, air leak, drying sputum, difficulty in coughing up phlegm and claustrophobia. As an emerging technology, high flow nasal oxygen (HFNO) has many advantages in airway humidification, tolerance and compliance which also can effectively improve pulmonary oxygenation function of patients with respiratory failure. Which therapeutic measure should be recommended for the patients with ALHF after extubation, NIV or HFNO? It is still unclear according to the latest management guidelines. So one perspective study will be launch to compare the difference between HFNO-group patients with NIV-group patients in re-intubation rate within 48 hours, oxygenation index, length of ICU stay, total hospital stay, mortality and compliance for evidence-based medicine.
This study aims to compare the clinical profile and outcomes of acute coronary syndrome patients with diabetes and without diabetes.
Purpose: Exaggerated sympathetic nervous system (SNS) activity associated with low heart rate variability (HRV) is considered as a trigger of cardiac arrhythmias and sudden death. Regular exercise training is efficient to improve autonomic balance. In 2013, the investigators published that a single session of an optimized short-high intensity interval exercise with passive recovery (HIIT) protocol was efficient in chronic heart failure (CHF) patients for enhancing vagal tone and to decrease arrhythmias in the 24-h post exercise period when compared to a single session of moderate intensity continuous exercise (MICT). Nevertheless the effects of HIIT training performed on several weeks have never yet been studied on the parameters described by Coumel's triangle (the arrhythmogenic substrate, the trigger factor as premature ventricular contraction and the modulation factors of which the most common is the autonomic nervous system). The aim of this study was to verify the superiority of HIIT to enhance parasympathetic activity, cardiorespiratory fitness and cardiac function when compared to MICT in a short and intense cardiac rehabilitation program.
This randomised controlled study investigates the effect of Kinesio Taping on pulmonary function, respiratory muscle strength, functional capacity, functional mobility, hand grip strength, quality of life and level of depression in patients with chronic heart failure (CHF). The study also compares effects of Kinesio Taping and Inspiratory Muscle Training (IMT). There were 3 study groups: The experimental group received Kinesio Taping; the breathing exercise group received IMT; and the control group received no interventions.
