Congestive Heart Failure is the result of a number of diseases affecting the heart, causing the heart's failure to properly meet the body demands for blood circulation. In spite of advances in drug therapy, it remains a significant public health problem. Pharmacologic antagonism of the beta-adrenergic receptors shifting the autonomic balance in the direction of greater vagal influence is a well-proven treatment for heart failure patients, although there are patients who cannot tolerate, or only partially benefit from such a treatment. It has been proven in the past and well established that parasympathetic nerve stimulation can slow the rate of the heart and reduce the workload of the heart. Therefore, the potential benefit of vagus nerve stimulation, hence parasympathetic activation, for treatment of heart failure is substantial. In this study, the safety and efficacy of a new vagus nerve stimulating system will be evaluated. This study will compare whether the new device improves Heart Failure parameters in Class II - III Heart Failure patients.
NCT01308866
BACKGROUND: Mediterraneans have traditionally a low cardiovascular risk, although emerging lifestyles might change the trend. The aim of this study is to assess if hypercholesterolemic patient involvement in the preventive decision with the help of a decision aid has an impact on cardiovascular (CV) risk reduction superior to usual care. METHOD: The design is a cluster randomised clinical trial. Participants are hypercholesterolemic patients (\>200 mg/dl or c-LDL\>130) from four primary care teams of Barcelona. Patients with previous CV events, age over 75 years or cognitive impairment are excluded. It is expected to create two cohorts of 139 patients each one. The randomisation is by doctor. Intervention group will receive information about their CV risk and the risk and benefits of different preventive measures. They will have access to a decission aid that will help them in the choice of the preventive measures.The material (printed and software) is adapted to the Catalan Population using local CV risk tables and will meet the CREDIBLE and DISCERN criteria. STUDY VARIABLES: Sociodemographic variables, CV risk factors, subjective health (SF 12), decisional conflict, anxiety/depression, analytic controls, treatment, treatment adherence, compliance and resources use. Basal evaluation and 3, 6, 12 month assessment. The study, financed by FIS, will begin the 01-07-2007. RESULTS: The expected results are a higher reduction on the CV risk factors in the intervention group versus regular care. CONCLUSIONS Study will provide a tool to be used in Spanish and Catalan population.
