Filter by:Heart failure is the most common hospital admission diagnosis and shows increasing incidence and prevalence in Germany, the United States and worldwide. Improvements in the primary treatment conditions for e.g. myocardial infarction and reduced primary mortality has resulted in an increasing group of patients with secondary cardiac abnormalities including chronic heart failure. Progressive cardiac dysfunction and failure are associated with exercise intolerance, volume retention, nocturia, dyspnoea among others. The most severe progression of heart failure is cardiac decompensation (also called: acute heart failure) and cardiogenic shock. Volume retention, abnormal renal function and diuretic resistance are hallmarks of this clinical phenotype. Currently, the only available treatment is diuresis through various combinations of diuretics and the addition of cardiac inotropes when cardiac hypoperfusion is documented. Patients with acute decompensated heart failure (ADHF) often develop a state of diuretic resistance characterized by a need of rising dosages of diuretics for adequate diuresis and urine production. ADHF patients also show metabolic abnormalities including insulin resistance or type 2 diabetes mellitus. Empagliflozin is a potent and selective inhibitor of the sodium glucose cotransporter 2 (SGLT2) used in the treatment of type 2 diabetes. By inhibiting SGLT2, empagliflozin reduces renal glucose reabsorption and increases urinary glucose excretion. In addition to reducing hyperglycaemia, empagliflozin is associated with osmotic diuresis, reductions in weight and blood pressure without increases in heart rate, and has favourable effects on markers of arterial stiffness and vascular resistance. The investigators propose a single center exploratory study to test the hypothesis that the application of empagliflozin in addition to standard diuretic regimens increases urine output, decreases the need for further acceleration of diuretic regimens, and positively influences renal function as well as metabolism including insulin resistance in ADHF patients. Thereby, empagliflozin may be effective in the prevention of complex cardio metabolic alterations involved in ADHF.
This is a Phase I, randomized, double-blind, placebo-controlled study to assess safety, pharmacokinetics and pharmacodynamic parameters of CDR132L in patients with stable heart failure of ischemic origin (NYHA 1-3).
There is strong evidence that specific types of exercise can improve health and physical function in older adults. While community exercise classes exist, many older adults with chronic conditions may need guidance from credentialed exercise professionals to ensure sufficient dose and progression and to address fears or low exercise self-efficacy. Furthermore, low protein intake among older adults is common and initiating exercise when nutrition is inadequate may cause weight loss and limit gains in muscle strength. The primary goal is to determine the feasibility of implementing the MoveSTroNg program under real-world conditions, measured through referral and recruitment to the program and study retention and adherence rates.
This study is to test a low-cost, simple vitamin C supplementation intervention, that is, comparing placebo to 500 mg/day vitamin C and 1 gram/day vitamin C daily to assess feasibility and acceptability of vitamin C supplementation and effects on serum vitamin C level, health-related quality of life (HRQOL), symptom burden, oxidative stress, and cardiac function.
Consumptive coagulopathy is associated with increased mortality in patients with heart failure (HF). Physical activity influences the risk of major vascular thrombotic events. This study investigates how high-intensity interval training (HIIT) affects the capacity of endogenous thrombin generation (TG) by modulating circulatory procoagulant microparticles (MPs) in HF patients. Thirty-eight HF patients and 38 age- and gender-matched normal counterparts (NC) were recruited into this study. The HF group performed HIIT (3-min intervals at 40% and 80%VO2peak) on a bicycle ergometer for 30 min/day, 3 days/week for 12 weeks, whereas the NC group did not receive any form of intervention. Plasma TG kinetics, procoagulant MPs, coagulation-related factors, and oxidative stress/proinflammatory status were analyzed. The results demonstrated that the HF group exhibited (i) less endogenous thrombin potential (ETP) and TG rate, (ii) lower concentration/activity of tissue factor (TF) and counts of TF-rich MPs derived from blood cells, and (iiii) higher vascular endothelial shedding and plasma myeloperoxidase and interleukin-6 concentrations, compared to the NC group did. However, HIIT elevated plasma ETP and TG rate, as well as, TF concentration/activity and blood cell-derived procoagulant MP levels in the HF patients. Moreover, the exercise regimen also decreased vascular endothelial shedding and plasma myeloperoxidase and interleukin-6 concentrations in patients with HF. Hence, we conclude that HF reduces the capacity of endogenous TG in plasma, which is associated with decreased (or consumed) circulatory procoagulant MP levels. However, HIIT alleviates HF-declined endogenous TG capacity and vascular endothelial damage through recuperating TF-related coagulation activity and suppressing oxidative stress/proinflammatory status.
The objective of this proposal is to compare clinical outcomes, implementation metrics (i.e., patient reach and clinician adoption), and clinician preferences of two designs (customized vs. commercial) of a clinical decision support (CDS). Beta blocker prescribing for patients with heart failure will be used as a test case. The best practices in CDS design, including the user-centered design will be incorporated into the customized CDS and compared to a commercially-available CDS in the electronic health record using a cluster randomized trial.
The purpose of this study is to determine if enhanced endothelial arterial distensibility observed with heat therapy translates into improved cardiorespiratory fitness. The following aims are proposed: Aim 1: to determine if chronic heat therapy results in improvements in cardiovascular function. Aim 2: To examine potential mechanism(s) of action of heat therapy in cardiovascular function.
Patients with heart failure have decreased exercise tolerance, balance problems, and fall risks. The purpose of this research was to investigate the effect of an exercise program based on the Empowerment Model for participants with heart failure. This randomized, controlled study including pre-test/post-test and the measurements were performed between January-November 2014 at a university hospital in Izmir, Turkey. Intervention group (n = 11) and control group (n = 10) participated in the research. The intervention group received 45-60 minute individual training and 12 weeks of individual follow-up. The weekly motivational phone calls structured according to the empowerment model and home visits when necessary were repeated. Patients in the control group did not receive any intervention except for their routine treatment. Data were collected before the education of exercise and after 12 weeks; sociodemographic data questionnaire, pedometer, accelerometer, Berg Balance Scale, HF Empowerment Scale, estimated weekly exercise monitoring form and exercise booklet had been utilised. The SPSS statistical package program was used to analyze the data.
To assess the impact of the socio-economic level on the effectiveness of a comprehensive multidisciplinary program of transitional care for crhonic heart failure patients (primary objective); to analyze this specifically in the various chronic management profiles of CHF patients and to study the associations between socio-economic level and other psychosocial aspects (secondary objective).
Researchers are observing the values of proEnkephalin (PENK) via a blood draw in hospitalized patients that are volume overloaded requiring diuresis. If changes in PENK are found, physicians may predict values of change in kidney function during treatment.
