This study evaluates the state of the cardiac sympathetic activity and the severity of ventricular dyssynchrony in chronic heart failure patients and assesses the capabilities of radionuclide indication methods in determining the prognosis and evaluating the results of cardiac resynchronization therapy in chronic heart failure patients.
The Human leukocyte antigen G (HLA-G) is a non-classical, major histocompatibility complex class I (MHC-I) protein that modulates the immune response, inhibiting it in most cases. Physiologically expressed in the cells of some tissues, it increases in inflammatory reactions. Inflammation appears to play an important role in the development of chronic heart failure. This study aims to evaluate the levels of soluble HLA-G in patients with heart failure and to investigate the relationships between HLA-G and other clinical-functional parameters of the disease. Investigators hypothesize that the plasma levels of HLA-G could correlate with the clinical status of heart failure and could provide indications on patient's prognosis.
Heart failure (HF) is a multisystemic disease leading to exercise intolerance and fatigue. Supervised physical training improves functional capacity, quality of life and reduces hospital admissions in HF patients. In this way, home physical training may be a good alternative to patients who, for any reason, cannot perform supervised training. Objective: To asses the effects of a home-based training program on functional capacity, sedentary lifestyle and quality of life of patients with chronic HF compared to supervised training.
Purpose: Exaggerated sympathetic nervous system (SNS) activity associated with low heart rate variability (HRV) is considered as a trigger of cardiac arrhythmias and sudden death. Regular exercise training is efficient to improve autonomic balance. In 2013, the investigators published that a single session of an optimized short-high intensity interval exercise with passive recovery (HIIT) protocol was efficient in chronic heart failure (CHF) patients for enhancing vagal tone and to decrease arrhythmias in the 24-h post exercise period when compared to a single session of moderate intensity continuous exercise (MICT). Nevertheless the effects of HIIT training performed on several weeks have never yet been studied on the parameters described by Coumel's triangle (the arrhythmogenic substrate, the trigger factor as premature ventricular contraction and the modulation factors of which the most common is the autonomic nervous system). The aim of this study was to verify the superiority of HIIT to enhance parasympathetic activity, cardiorespiratory fitness and cardiac function when compared to MICT in a short and intense cardiac rehabilitation program.
This randomised controlled study investigates the effect of Kinesio Taping on pulmonary function, respiratory muscle strength, functional capacity, functional mobility, hand grip strength, quality of life and level of depression in patients with chronic heart failure (CHF). The study also compares effects of Kinesio Taping and Inspiratory Muscle Training (IMT). There were 3 study groups: The experimental group received Kinesio Taping; the breathing exercise group received IMT; and the control group received no interventions.
The objective of the study is to demonstrate that in patients with chronic heart failure who receive optimal medical treatment for this condition and have indication for Cardiac Resynchronisation Therapy, the implantation of a pacemaker (index group) is not inferior to defibrillator (control group) with respect to all-cause mortality.
Patients with chronic heart failure (CHF) and reduced left ventricle ejection fraction benefit from cardiac resynchronization therapy (CRT) and implantable cardioverter defibrillator (ICD). Currently used devices, besides delivering low and high-energy therapies, record patient's activity and many hemodynamic parameters. However, increasing numbers of patient with CRT and ICD devices produce overload of cardiology centers where patients are admitted to ambulatory visits. Contrarily, there are technological possibilities for remote monitoring proven to be effective in recognizing damage of the implanted device and risk of exacerbation of chronic heart failure. Patients' registries show that majority of ambulatory visits are unproductive and do not result in significant modification of device's parameters. Promising experiences with application of data mining and machine learning techniques allow us to assume probable benefits from using modern methods of data analysis in determination of requirement for ambulatory follow-up on basis of data gathered through telemonitoring and clinical assessment of a patient. Aim of the study is to find multivariate model predicting the requirement for ambulatory follow-up of IECD.
VINDICATE 2 will be a randomised, placebo-controlled, parallel group, double-blind study of vitamin D versus placebo in otherwise optimally-managed patients with CHF due to LVSD and vitamin D deficiency (<50nmol/L). The intervention will be a daily dose of 4000IU (100µg) per day or matching placebo for a minimum of 2 years and a maximum of 4 years.
The purpose of this study is to evaluate efficacy of rhNRG-1 in reducing the death rate of heart failure subjects with baseline NT-proBNP level ≤1600 pg/mL and NYHA class II to III.
The purpose of this study is to determine the safety and effectiveness of intracoronary infusion of autologous cardiac stem cells in patients with ischemic cardiomyopathy.
