Filter by:The study is observational, prospective, including patients undergoing CRT-D / CRT-P implantation in the department of cardiology. In the current project, the researchers assumed that the improvement in cardiac function obtained in patients qualified according to the ESC / PTK guidelines for resynchronization therapy may improve renal function in a prospective 12-month follow-up. In addition, it is planned to take into account the possibility of temporary deterioration of kidney function, which may occur immediately after implantation of the resynchronization device due to the nephrotoxic effect of the contrast agent.
The purpose of this study is to assess the safety, efficacy and optimal dose of TSG-01, an innovative drug with ginsenosides as its main components, in the treatment of patients with chronic heart failure(CHF). Preclinical studies have revealed that TSG-01 promote myocardial energy metabolism and ATP production, reduce the damage of human pulmonary microvascular endothelial cell connection, resist arrhythmia, and regulate the lipid metabolism disorder caused by myocardial ischemia. Results from CHF animal models(dog, rat) showed that TSG-01 significantly increase coronary blood supply, improve myocardial contractility, reduce heart expansion and pulmonary edema. Besides its potency of improving heart function, TSG-01 was found to induce diuresis without obvious effect on urine potassium in rats. TSG-01 has been approved by CFDA for a clinical trial on the treatment of CHF (Approval No. 2018L03012). A randomized, double-blind, multicenter, placebo-controlled phase IIa clinical trial is now being conducted in 5 hospitals in China. A total of 90 cases of CHF caused by coronary heart disease are included and randomly divided into three groups: high-dose, low-dose of TSG-01 and placebo group. NYHA functional class, 6-minute walk test(6MHWT) distance, NT-proBNP, left ventricular ejection fraction(LVEF), echocardiographic parameters (LVESV, LVEDV, and heart size) and MLHFQ score are measured before, during and after treatment to evaluate the benefits of TSG-01 therapy in patients with CHF.
The study focuses on the development of a new personalized approach to diagnostics and surgical treatment of patients with ischemic cardiomyopathy. The algorithm for selection of patients for certain type of cardiac surgery will be developed. The models for prediction of the risks and outcomes of cardiac surgery will be elaborated to reduce the rate of complications in the early and long-term postoperative period in patients with ischemic cardiomyopathy. Imaging modalities, methods for assessement of structural and functional state of the myocardium, biochemistry testing, immunohistochemical examination, and myocardial biopsy studies will be used to achieve these goals.
The investigators hypothesize that the airway pressures generated by High Flow Oxygen Therapy could have a beneficial impact in patients with heart failure, particularly by lowering capillary pulmonary arterial pressures. However, results compared to Non-Invasive Ventilation are difficult to predict due to the lack of data in the literature.
To demonstrate that a virtual Heart Failure Clinic (HFC) based on patient self-management using Pulmonary Artery Pressure (PAP) monitoring is superior to usual care of HFC, leads to decreased: hospital admissions for heart failure (HF), emergency department consultation and/or unplanned intravenous heart failure therapy and cardiovascular death, compared to a regular HFC, has low device-related complications and is cost-effective, in New York Heart Association (NYHA) class III and II (requiring diuretics) patients.
Chronic, ambulatory heart failure patients will be given ketone ester dietary supplementation to determine therapeutic efficacy, metabolic adaptation, pharmacokinetics, associated cognitive changes, and safety within this patient cohort in order to establish preliminary data to later conduct a multi-center randomized clinical trial.
Aims: To assess the efficacy of symptom-limited stair-climbing test (SLSCT), in determining the exercise capacities of patients with chronic heart failure (CHF) in comparison with cardiopulmonary exercise test (CPET) and 6-minute walk test(6MWT) and to interpret the results according to the clinical status of the patients. Methods: Thirty-one patients, aged 50-75 years, with stage II-III CHF according to the New York Heart Association Classification and left ventricular ejection fraction (LVEF) of ≤45% were included. The demographic and clinical characteristics of the patients were recorded. Exercise capacity was assessed by SLSCT, 6MWT, and CPET. The duration of patients' performance in the test, reasons for ending the test and predicted maximal oxygen consumption (VO2max) were recorded. Heart rate (HR), blood pressure (BP), dyspnoea severity [Modified Borg Scale (MBS)] and peripheral oxygen saturation were recorded. Pulmonary functions were assessed by spirometry.
This study will use a novel CPX test that incorporates instantaneous assessment of maximal isokinetic cycling power at V̇O2peak to elucidate the mechanisms that limit V̇O2peak in CHF, and compare these responses with age-matched controls.
The purpose of this study is to optimize the complex treatment of chronic heart failure of non-ischemic etiology by supplementing umbilical cord mesenchymal stem cells to the standard drug therapy.
Every day many patients affected by chronic life-limiting illnesses are admitted into Internal Medicine wards, coming from the Emergency Department. Many studies suggest that providing palliative care to these patients may improve their end-of-life care while reducing costs by minimizing futile treatments and unwanted intensive care unit admissions. Consequently, there is a strong need for acute care hospitals to more vigorously identify patients entering the final phase of their lives as well as their specific care needs. In a previous study the investigators screened for need of palliative care patients affected by progressive chronic diseases by means of a tool, based on the Italian Society of Anesthesia, Analgesia, Resuscitation, and Intensive Care - SIAARTI - position paper reporting criteria for patients with end-stage chronic organ failures, and on the specific clinical indicators elaborated by the National Comprehensive Cancer Network (NCCN) for patients with locally advanced/metastatic cancer. In a further pilot study, the investigators compared the outcomes of PC patients depending on whether the palliative care team evaluated such patients only if requested by the physician staff or routinely, irrespectively of a specific request, finding a significant increase of discharges after the activation of an appropriate PC service or scheduled PC ambulatory visit. In the present study the investigators enroll chronically ill patients admitted to an Internal Medicine Unit from the Emergency Department, to be screened for palliative care need, using the previously cited SIAARTI/NCCN screening tool (Extended Screening Tool - EST), or using a Simplified Screening Tool (SST), derived from the first instrument, which preliminary showed a superimposable efficacy. This latter tool has advantages related to much more shortness and therefore simplicity in the administration to a seriously ill patient and is much less time consuming, allowing the physician to use it routinely. The aim of the study is to verify the accuracy of the SST in identifying chronically ill patients in need of a PC approach, in comparison to the SIAARTI/NCCN tool (EST). If the SST would show good accuracy, an easily manageable tool for the assessment of PC needs in chronically ill patients would be available for the daily routine.
