Filter by:The main purpose of this study is to analyse test-retest-reliability of functional quantification of endothelial dysfunction through puls-amplitude-tonometry in patients with heart failure with preserved/reduced ejection fraction, pulmonary hypertension, arterial hypertension and diabetic nephropathy. In the same group, test-retest-reliability of circulating endothelial cells as well as test-retest reliability of non invasive cardiac output Monitoring will be observed and analysed.
Aims: Advance care planning (ACP) is considered to be one of the most promising interventions to enable patients with life limiting illnesses to receive treatment at the end of life (EOL) according to their own preferences and to promote EOL conversations between patients and their health care providers. Through a 2-arm randomized controlled trial (RCT) of patients with Class III and IV heart failure (New York Heart Association Functional Classification), we propose to assess: 1. Whether patients in the ACP arm have a greater likelihood of receiving EOL care consistent with their preferences as stated in the latter of the last ACP document or the last patient interview, compared to patients in the control arm. 2. Heath care costs during study duration between patients in ACP and control arms. 3. Patient's understanding of own illness and their participation in decision making between the ACP and control arms. 4. Patient's quality of life, anxiety and depression between ACP and control arms. Methodology: A total of 254 patients with advance heart failure will be randomized to receive intervention (ACP arm; N=127) or usual care (control arm; N=127). The RCT will be conducted at the National Heart Centre and Singapore General Hospital. Patients in both arms will be followed for one year or till death, whichever is earlier, and interviewed every 4 months during this duration. Clinical Significance: If benefits of ACP are shown to add value through this trial, then this study will help to promote acceptance of ACP among patients and health care providers across Singapore and elsewhere.
Lead survivability will be summarized.
The primary endpoint is the incremental cost effectiveness ratio (ICER), defined as the combined clinical endpoint "days alive and not in hospital nor stationary care per days in study" and the change in total cost compared to that of the control group.
The HIV/HEART study (HIVH) is an ongoing, prospective, multicentre trial that was conducted to assess the incidence, the prevalence and the clinical course of cardiovascular diseases (CVD) in HIV-infected patients. The study population includes outpatients from specialized HIV-care units of the German Ruhr region, who were at least 18 years of age, were known to have a HIV-infection and exhibited a stable disease status within 4 weeks before inclusion into the trial. From March 2004 (Pilot phase) to May 2014 (7,5 year Follow-up) 1481 HIV+ patients were recruited in a consecutive manner. The standardised examinations included a targeted assessment of medical history and physical examination. Blood was drawn for comprehensive laboratory tests including HIV specific parameters (CD4 cell count, HIV-1 RNA levels) and cardiovascular items (lipid concentrations, BNP values and renal parameters). Furthermore, non-invasive tests were performed during the initial visit, including additional heart rate and blood pressure measurements, electrocardiogram (ECGs) and transthoracic echocardiography (TTE). Examinations were completed in accordance with previously defined standard operating procedures. CVD were defined as coronary, cerebrovascular, peripheral arterial disease, heart failure or cardiac vitium.
Objective: The Ultrasonic Cardiac Output Monitor (USCOM) is a non-invasive, quantitative method for measuring and monitoring cardiovascular haemodynamic parameters in patients. The aims of this study are: 1. To investigate whether USCOM-derived haemodynamic parameters such as Cardiac output (CO), inotropy and oxygen delivery (DO2) have a role in the diagnosis of patients with a compensated heart failure syndrome (cHFS) or acute decompensated heart failure syndrome (adHFS) 2. To investigate whether USCOM-derived haemodynamic parameters such as CO, inotropy and DO2 correlate with heart failure staging, especially New York Heart Association (NYHA) class and American Heart Association (AHA) stage. 3. To investigate whether USCOM-derived haemodynamic parameters such as velocity time interval (vti), stroke volume (SV), CO, SV index (SVI), CO index (CI), inotropy and DO2 correlate with ejection fraction. 4. To investigate whether USCOM-derived haemodynamic variables may be used as prognostic indicators of 30-day, 6-month and 1-year Major Adverse Cardiac Events (MACE). 5. To evaluate the agreement between hemodynamic measurements obtained using the Ultrasonic Cardiac Output Monitor (USCOM®; USCOM Ltd., Sydney, Australia), and reference standards as determined by 2 Dimensional echocardiography (2D-echo) measurements in groups of haemodynamically stable and unstable adult patients. Design: This prospective observational cohort study will be conducted in the Prince of Wales Hospital in Hong Kong. Setting and Subjects: Patients will be screened and recruited from adult patients either scheduled for elective 2D-echo at a cardiology clinic at the Prince of Wales Hospital, or attending the emergency department at the Prince of Wales Hospital. Interventions: Haemodynamic measurements made using the USCOM and 2D-echo will be compared. In order to assess inter-observer variability, a second, blinded operator will repeated 15% of scans.
Purpose :Research into the impact of Qiliqiangxin capsule on IFN-γ，IL-4，NT-proBNP in dilated cardiomyopathy patients with heart failure. Methods :Data were collected from the patients with idiopathic dilated cardiomyopathy ( cardiac function NYHA Ⅱ-Ⅳ) in the first affiliated hospital of Harbin Medical University from May 2012 to April 2014. These 30 cases were treated under the recommendations of normal diagnosis and treatment in cardiomyopathy. This experiment was randomized double-blinded，the experimental interferences were avoided and patients were divided into the experimental group and the placebo group. The patients in experimental group received the relevant tests and inspections before the beginning of experiment，signed the informed consent. Then the investigators get the venous blood centrifugalization and cryopreservation. The patients take the medicine qiliqiangxin three times per day，four tablets at a time. Afrer a month，the investigators evaluated the symptoms，the function of heart，blood pressure，heart rate and keep blood specimens. Three and six month later，electrocardiogram and echocardiography were taken and the determination of the NT - proBNP was done. The placebo group was followed up in the same way.
The purpose of the CardioMEMS HF System Post Approval Study (PAS) is to evaluate the use of the CardioMEMS HF System in patients with NYHA class III heart failure in a commercial setting.
This is a research study being conducted to better understand the impact of exercise training on changes on the structure and function of the heart. Exercise training in patients with heart failure has been shown to be beneficial at decreasing symptoms of heart failure and improving overall functional capacity or capacity to exercise. However the mechanisms responsible for this are still unclear. This study will look specifically at how exercise creates changes within the hearts filling ability, the hearts pumping strength as well as the hearts ability to rebuild.
Peripheral blood and blood following a pulmonary wedge pressure will be obtained from patients undergoing right heart catheterizations.
