Filter by:Study Aim is creation of the Hospital Register of patients with heart failure with preserved ejection fraction (HFpEF) for a comprehensive assessment of the influence of gender characteristics, clinical and anamnestic factors, body composition, topical characteristics of congestion, instrumental data and markers of cellular inflammation and stress on immediate and long-term outcomes in patients with acute decompensated heart failure with preserved ejection fraction. During the study it is planned to assess gender, clinical and anamnestic indicators preceding hospitalization of patients in the hospital; characterize the features of comorbid status in the studied group of patient; study the features of drug therapy at the prehospital stage and during hospitalization in the study group of patient; assess adverse hospital outcomes and outcomes 6 months after hospital discharge and identify factors associated with them; assess body composition in patients with acute decompensated heart failure with preserved ejection fraction in obese patients upon admission to the hospital; characterize the severity and topical characteristics of congestion and compare with the phenotypes of acute decompensation of heart failure; asess adverse in-hospital outcomes and outcomes 6 months after hospital discharge and identify factors associated with them; conduct a clinical and instrumental examination of patients diagnosed with compensated and decompensated HFpEF, verified by echocardiography at rest, as well as in patients with HFpEF verified after an additional diastolic stress test with assessment of intracardiac hemodynamic; analyze the serum concentrations of biochemical markers associated with cellular stress in these groups of patients, as well as in the control group of apparently healthy people; conduct an analysis of associations of biomarker levels with clinical characteristics of patients, the presence of comorbid diseases, including obesity, as well as with data from instrumental examination methods; assess the diagnostic capabilities of HFpEF, defined by various criteria, based on the concentration of the new biomarkers The results obtained will allow us to evaluate the characteristics of the course and outcomes of the disease in Moscow patients, depending on the phenotype of acute decompensation of HFpEF, hospitalized in the hospital during the study period. It is expected to identify phenotypes of acute decompensation of HFpEF that affect the duration of hospitalization and the development of adverse outcomes in the hospital and long-term period of the disease.
Non-invasive ventilation (NIV) has been widely used in heart failure patients with supporting evidence. However, the drawbacks and contraindications associated with NIV limit its applicability in certain patients. Recently, high-flow oxygen therapy (HFOT) has gained popularity, particularly in the context of the COVID-19 pandemic, due to its documented benefits, improved patient comfort and fewer contraindications. Studies have suggested that HFOT can generate positive end-expiratory pressure (PEEP) similar to NIV, thereby increasing end-expiratory lung volume. However, the specific effects of PEEP remain unknown, as previous research only monitored the upper airway pressure. Therefore, this study aims to explore the flow-pressure relationship between HFOT and NIV in heart failure patients using electrical impedance tomography (EIT). This prospective randomized crossover clinical trial will be conducted at a single medical center with multiple intensive care units. Participants will be randomly assigned to Groups A and B using a computerized randomization process. Each group will undergo specific protocols for 5-10 minutes per phase, during which parameters including respiratory rate, heart rate, blood pressure, peripheral oxygen saturation, and oxygen concentration will be recorded. NIV will be administered in continuous positive airway pressure (CPAP) mode. Additional parameters such as tidal volume, respiratory rate, minute ventilation, leak flow, and peak inspiratory pressure will be recorded for NIV. The study protocols for Group A will follow the sequence of oxygen mask, HFOT 40L, HFOT 50L, HFOT 60L, oxygen mask, CPAP 4cmH2O, CPAP 5cmH2O, and CPAP 6cmH2O. Group B will follow the sequence of oxygen mask, CPAP 4cmH2O, CPAP 5cmH2O, CPAP 6cmH2O, oxygen mask, HFOT 40L, HFOT 50L, and HFOT 60L. This means that each intervention will be performed in the order listed, with one intervention completed before moving on to the next. The participants will be positioned in a semi-recumbent position at 45 degrees, and the EIT belt will be placed around the fifth (or sixth) intercostal space for monitoring. The EIT signals will be filtered with a cut-off frequency set at 10 beats below the current heart rate. The entire procedure is estimated to take approximately 1-1.5 hours, and recalibration will only be performed in case of significant signal abnormalities. All data will be stored for offline analysis.
Conduction system pacing vs biventricular resynchronization therapy in systolic dysfunction and wide QRS: mortality, heart failure hospitalization or cardiac transplant (CONSYST-CRT II trial). Superiority trial that aims to study the composite endpoint consisting of all-cause mortality, cardiac transplant or heart failure hospitalization at 12-month follow-up.
The purpose of this pilot feasibility study is to test a pharmacist-facing clinical decision support tool designed to increase adherence to guideline-directed medical therapy and evaluate the tool using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) evaluation framework.
The study is a non-randomized, two-part, open label, prospective single-site, single arm, safety and performance study. The study is designed to collect acute and long-term clinical data and user reported outcome data from using the PreSens-Catheter and PACER Software during cardiac catheterization and Cardiac Resynchronization Therapy (CRT) device implantation procedures. Subjects with indication for arterial catheterization and CRT will be included.
This clinical study is a multicenter, randomized, controlled clinical study to evaluate the effectiveness of using the noninvasive lung fluid monitoring system based on remote dielectric sensing in guiding the treatment of heart failure.
NT-proBNP does not adequately identify HF(pEF) in people with suspected HF at low levels, particularly in patients with obesity. This study will investigate: 1. alternative cut-offs for NT-proBNP to identify HF(pEF) in people with suspected HF and obesity 2. novel candidate biomarkers to identify HF(pEF) in people with suspected HF and obesity. 3. novel candidate biomarkers to identify HF(pEF) in people with suspected HF and NT-proBNP <125 ng/L 4. the prevalence of HF in people with suspected HF and low NT-proBNP <125 ng/L)
This is a randomized quality improvement project to evaluate the impact of an audit and feedback intervention to motivate pharmacists to provide heart failure (HF) medication management to patients in the Veterans Health Administration (VHA) Sierra Pacific region (VISN 21). The results of this project could provide guidance for how to successfully scale a pharmacist-based HF remote management program in the VHA more broadly. Pharmacists providing clinical care as part of Patient Aligned Care Team (PACT) within VHA VISN 21 will be included. Pharmacists will be randomized to one of 3 arms in a 1:1:2 ratio: (1) monthly audit and feedback of HF medication titration activities (AF) vs. (2) educational resources and monthly notification of HF medication titration actions in addition to a list of potential patients for HF optimization (AF+) vs. (3) usual care without audit and feedback (UC). Pharmacists across all three arms will be given access to shared educational resources on HF pharmacist care and educational webinars. Six months after the intervention, rates of pharmacist HF medication titration encounters will be compared among the 3 groups.
The purpose of the study is to assess the impact of HeartLogic-guided management on clinical outcomes among patients implanted with an eligible cardiac device.
This is a retrospective, researcher-initiated, database-based study that will retrospectively observe the treatment and medication patterns of about 22,500 patients with heart failure from 25 heart failure centers and 25 non-heart failure centers in the database of heart failure center. The proportion of patients with heart failure treatment drugs reaching the target dose recommended in the guidelines and discontinuation rate will be observed at 1 month, 3 months and 12 months follow up time point. The purpose of this study is to illustrate the current HF treatment status in HF center hospitals and non-HF center hospitals, which may provide insights for improving the clinical practice of heart failure treatment in China, and promote the standardization of heart failure treatment in China.
