Filter by:The objective of this 3-year project is to develop myocardial MRS, in particular lipid (triglyceride) and creatine resonances, as imaging biomarkers for patients with heart failure (HF). Investigators will elucidate how and, to what extent, lipid and creatine levels of the heart contribute to heart failure. The first year is a cross-sectional study. Investigators aim to compare the MRS of normal subjects and that of stable HF patients in recovery with normal or impaired ejection fraction (EF). Total 60 subjects will be enrolled, with 20 subjects in each group. In the 2nd and 3rd years, investigators plan a prospective longitudinal study of 40 subjects. Enrolled patients will be evaluated with cardiac MRS at three time points, i.e., disease onset, 6 months and one year after treatment, and will be followed up until the end of this project (1.5~3-year follow up). In total 120 MR scans will be performed in the 2nd and 3rd years. The resonances from cardiac MRS, including creatine and lipids, will be correlated with the disease course, patient biochemistry data and clinical outcome. Investigators expect to make MRS to become an integral part of a clinical cardiac MR protocol.
Although the traditional determinant of renal dysfunction in heart failure was suggested as decreased cardiac output and renal hypo perfusion, recent studies have demonstrated the association of persistent systemic venous congestion and kidney dysfunction. Relief of the congestion has demonstrated to improve renal functions in decompensated heart failure. The current trial was set up to investigate the changes of renal venous impedance and renal arteriolar resistivity indices with diuretic therapy, in patients with congestive renal failure. The investigators asked whether measurement of renal venous impedance index or renal arteriolar resistivity index can guide the practice of diuretic therapy.
Background: The cardiac resynchronization therapy (CRT) has been shown to improve symptoms and outcome of patients with congestive heart failure (HF), and depressed left ventricular ejection fraction (LVEF < 35 %). The rate of non-responders to CRT is estimated at 30 %. Yet, the impact of frailty on the response to CRT has not been studied, until now. Purpose : To assess the impact of frailty in the elderly, on the response to CRT.
External measure of thoracic fluid content (TFC) combined with vital signs (HR,respiratory rate(RR), posture and movements) using the technology developed by Kyma Medical Technologies while tracking clinical changes in acute in-hospital and chronic outpatient heart failure patients.
The study aims to assess the clinical and economic impact of a pharmaceutical care program initiated in the Emergency Department versus conventional follow-up of patients with decompensated heart failure/COPD.
The purpose of this clinical study is to observe the safety and efficacy of the multi-vector left ventricular (LV) lead in Chinese patients that are indicated for Cardiac Resynchronization Therapy (CRT).
The main purpose of this research is to determine whether injecting mesenchymal precursor cells (MPC) into the heart during surgery to implant a left ventricular assist device (LVAD) is safe. MPCs are normally present in human bone marrow and have been shown to increase the development of blood vessels and new heart muscle cells in the heart. In addition, this research is being done to test whether injecting the MPCs into the heart is effective in improving heart function.
Planned enrollment is approximately twelve subjects with stable chronic heart failure. Enrolled subjects will receive up to eight sequential days of continuous, stepwise, dose increasing, subcutaneous (SQ) infusions of open-label cenderitide via the Insulet Drug Delivery System. Planned infusion rates of cenderitide will be administered to subjects continuously during four, 48-hour infusion periods.
The aim of this descriptive study is to examine potential changes regarding inflammatory cytokine levels, depressive symptoms and quality of life over the course of the 4-week inpatient rehabilitation program which includes a cassette of modalities including counseling, psychosocial education and supervised exercise training as a main pillar, and to further investigate if there are correlations between changes in immune regulation, depressive symptoms and quality of life.
Association between serum magnesium and clinical outcome in patients with acute MI (AMI) with 1 year follow-up in 300 patients in regions supplied by desalinated drinking water (DSW) (Sheba MC) and 150 patients in regions with non-desalinated drinking water (DW) (Nahariya MC).
