Systolic Time Intervals in the Diagnosis of Heart Failure in Emergency Departement
Dyspneathe gold standard for the diagnostic of acute heart failure is based on clinical, biological (BNP levels) and echocardiographic findings, but still in some cases, the diagnosis is difficult and requires further investigations. BNP dosages and echocardiography are not always available in many medical centers, especially in emergency departements, and are expensive. we investigated the use of alternative methods, such as the systolic time intervals (STI), in the diagnosis of acute heart failure (AHF) in emergency departement patients consulting for dyspnea.
Biomarkers to Predict CRT Response in Patients With HF (BIOCRT)
Heart FailureThe prospective study aims: To determine the role and mechanism of biomarkers for prediction of response to CRT To determine the role of biomarkers and their effect on left ventricular remodeling in patients undergoing CRT.
Anti-Angiotensin-Receptor 1 (ATR1)-, Anti-Endothelin-Receptor A (ETRA)-Antibodies and T Cells in...
Cardiac FailureThe study aims 1) to determine autoantibody titers against the AGTR1 receptor and against the ETA receptor, 2) to characterize cytokine expression profiles of heart-specific activated T cells in patients with systolic heart failure. Auto-antibody titers and specific cytokine expression profiles in heart-specific activated T cells will then be correlated with heart failure progression and outcome.
Trajectory Changes of Coronary Sinus Lead Tip and Cardiac Resynchronization Therapy Outcome
Heart FailureLeft-Sided Heart Failure1 moreIn chronic systolic heart failure patients submitted to cardiac resynchronization therapy, the study aims at assessing whether geometric variations in coronary sinus lead tip trajectory throughout the cardiac cycle acutely induced by biventricular pacing, are predictive of the volumetric and clinical response to the treatment at six-month follow-up.
Role of USCOM in Adult Patients With Heart Failure
Acute Decompensated Heart FailureCongestive Heart Failure CompensatedObjective: 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: 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) 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. 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. 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). 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.
Lifestyle Change Program in Elderly Patients With Heart Failure
Heart FailureSummary Chronic heart failure continues to be one of the highest economic burdens in the United States, heavily influenced by frequent readmissions to the hospital. This study will examine whether patients 65 years and older, who have NYHA class II and III heart failure, will improve their symptoms after participating in a comprehensive 12-week lifestyle change program. The investigators will recruit potential subjects primarily from the Scripps Clinic heart failure clinic at the Torrey Pines campus. Qualifying subjects will be randomized to medical treatment as usual or the lifestyle program. The investigators will enroll 17 subjects into each group which will provide 80% power and an alpha of 0.05. The lifestyle change program consists of classes conducted three times a week for 12 weeks at the Scripps Center for Integrative Medicine. Each day participants will spend about four to five hours in a variety of classes such as monitored exercise, group support, mindful-yoga and meditation, vegetarian cooking classes, music-centered wellness, mind-body lectures, and resiliency training. The primary outcomes will focus on determining functional status and physical agility using the 6-minute walk test, handgrip strength, and NYHA class categories. In addition, the investigators will capture subjective physical status with a self-reported questionnaire. Cognitive assessment will be performed using the Montreal Cognitive Assessment tool. To capture the subject's overall self-reported improvement the investigators will use a quality of life and a depression questionnaire. Secondary endpoints include hospital admission rates and all-cause mortality.
Impact of Advance Care Planning on Care for Patients With Advanced Heart Failure
Heart FailureAims: 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: 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. Heath care costs during study duration between patients in ACP and control arms. Patient's understanding of own illness and their participation in decision making between the ACP and control arms. 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.
Cardiac Assessment of Patients With Hip Implants
CardiomyopathyCardiac FailurePRIMARY OBJECTIVE To establish the effect of metal ion release from metal hip implants on cardiac function STUDY OUTCOME MEASURES To assess the effect of metal ions from hip implants on cardiac function as measured by Cardiac Magnetic Resonance Imaging (CMR) and Echocardiogram. This involves the surrogate detection of cobalt ion deposition within cardiac tissues and assessment of ejection fraction and tissue characterization (with and without contrast). STUDY IMPACT With 60,000 patients having a metal on metal (MOM) hip implant in the United Kingdom (UK), and over a million worldwide, there is need to clarify this important question, which is the source of significant concern amongst patients and surgeons alike. Also, this problem is not unique to MOM hips since all hip implants contain metal and as seen in various case reports high blood cobalt levels have arisen after catastrophic failure (e.g. fracture of a ceramic bearing surface) leading to abnormal wear of the implant and release of metal ions into the body. In the UK, over 80,000 hip implants are inserted annually.
