Filter by:Several studies have suggested that the endogenous electric field and its polarity stimulate the proliferation and migration of epithelial cells and therefore promote wound healing. WoundEL® will reproduce the endogenous electrical current to stimulate all the factors contributing to healing. Electrostimulation of wounds, including the WoundEL® device, is a therapy listed but not yet reimbursed in France. The aim of this study is to show that the WoundEL® electrostimulation device is superior to the reference treatments recognized by the HAS.
Systemic autoimmune myopathies are a heterogeneous group of rheumatic diseases with progressive skeletal muscle weakness. The relevance of the peripherical neuromuscular electrical stimulation has never applied in the patients with systemic autoimmune myopathies. Therefore, the main objective of the present prospective, randomized, investigator-blind, placebo-controlled study is to evaluate the safety and efficacy of the application of an acute peripherical neuromuscular electrical stimulation session in patients with systemic autoimmune myopathies.
Heart failure with reduced left ventricular ejection fraction (HFrEF) is the most common form of chronic heart failure in subjects ≤ 75 years of age. Beta-blocker therapy greatly reduces mortality and improves ventricular function in HFrEF patients, but 30-40% of patients do not show improvement in ventricular function with beta blockade. An extensive gene signaling network downstream from the beta1-adrenergic receptor, the primary target of beta-blocker therapy is likely important for development and progression HFrEF. Pathologic changes in this gene signaling network are only reversed towards normal levels when ventricular function improves. One potential mechanism for failure to improve ventricular function in HFrEF patients unresponsive to beta blocker therapy is a lack of heart rate reduction. Ivabradine is an FDA-approved medication believed to have therapeutic benefit in HFrEF patients through reduction in heart rate independent of beta-blockade. Ivabradine has been shown to reduce the risk of hospitalization for worsening HF in patients with stable, symptomatic chronic heart failure with reduced EF (≤ 35%)in sinus rhythm with resting heart rate ≥ 70 bpm and who are on maximally tolerated doses of beta blockers or who have a contraindication to beta blockers. Given the high rate of mortality and hospitalization of HFrEF patients even with current therapies, there is a large unmet need for improving HFrEF therapy. The goals of this study are to test the hypothesis that heart rate reduction is an important antecedent for improvement in ventricular function, and to identify components of the beta1-adrenergic receptor gene signaling network responsible for improvement in ventricular function caused by heart rate reduction.
The study is aimed at testing the hypothesis whether atrial fibrillary rate (AFR), as a measure of atrial electrical remodeling assessed from surface ECG, is predictive of sinus rhythm maintenance after electrical cardioversion. Earlier studies performed in a retrospective fashion suggested that high AFR exceeding 350-360 fibrillations per minute is an independent predictor of AF relapse after cardioversion, particularly in patients with duration of AF episode not exceeding 30 days, however this hypothesis has not been tested in a prospective study. CASAF is an observational study that will enroll patients with short duration (< 30 days) AF admitted for electrical cardioversion. Admission ECG will be extracted in a digital format and processed off-line for estimation of AFR. AF relapse will be assessed during 6-weeks long follow-up period during which ECG control will be scheduled at week 1 and 6.
