Filter by:Purpose: Heart Failure (HF) is a clinical multifactorial syndrome, it can cause arrhythmias for which international guidelines suggest the implantation of an implantable cardiac defibrillator (ICD). The educational nursing program would improve clinical outcomes in patients with HF and ICD like control their sickness, known and acknowledge symptoms, improve their skills to self-care. The main aim of this study is to assess how much the nursing-therapeutics skills and an educational intervention, in patients with HF during the follow-up period after the implantation of ICD reduces clinical costs, re-hospitalizations, and mortality at 180 days. Methods: The investigators start a multicenter randomized clinical trial. The sample is made of 128 subjects (64 patients treatment group and 64 control group). The investigators measured the self-care level administering to HF patients the "Self-Care of Heart Failure Index (SCHFI) v. 6.2", and the self-perception of own life quality using a Numeric Rating Scale from 0 to 100. Secondary outcomes recorded are i) the numbers of accesses to the ED (Emergency Department) and/or hospitalizations during the follow-up period, ii) mortality rate due to HF, and iii) infection rate of the device pocket. Data Analysis: Categorical variables will be presented in terms of frequencies and percentages. The statistical power was fixed at the 80%. Data will be considered significant for a p-value ≤ 0.05. The Cox proportional hazards model will be used to analyze mortality in subjects involved in the educational program.
Septic shock is a condition that is marked by severe infection causing hypotension requiring vasopressors to maintain adequate perfusion to vital organs. The Surviving Sepsis campaign, an international organization formed for the purpose of guiding the management of sepsis and septic shock, currently recommends norepinephrine as the first-choice vasopressor for septic shock. Phenylephrine, a vasopressor FDA-approved for use in septic shock, is recommended as an alternative vasopressor when septic shock is complicated by tachyarrhythmia to mitigate cardiac complications. This recommendation is based solely on experience with no scientific evidence to support this recommendation. The investigators will conduct an open-label randomized controlled trial (RCT) directly comparing phenylephrine and norepinephrine, two FDA-approved vasopressors that are both used in clinical practice for the management of septic shock. The investigators will perform this study with a population of patients that have septic shock to complete the following aims: Aim 1: Determine the incidence of tachyarrhythmias. Aim 2: Determine which vasopressor, phenylephrine or norepinephrine, is associated with a lower heart rate. Aim 3: Determine which vasopressor, phenylephrine or norepinephrine, is associated with a higher incidence of new tachyarrhythmias. Aim 4: Determine which vasopressor, phenylephrine or norepinephrine, is associated with less time in tachyarrhythmia. Aim 5: Determine which vasopressor, phenylephrine or norepinephrine, is associated with fewer complications, including cardiac complications. The investigators hypothesize that in this setting, phenylephrine will improve the management of septic shock when used as a "first choice" vasopressor by: 1. Decreasing the mean heart rate 2. Decreasing the incidence of new tachyarrhythmias 3. Decreasing the amount of time spent in tachyarrhythmia for patients who develop new onset and recurrent tachyarrhythmias 4. Decreasing the number of cardiac complications
it is a prospective, randomized, double-blinded, crossover study on the use of an association of omega 3 fatty acids, astaxanthin, vitamin E and hawthorn (ritmonutra) in subject affected by symptomatic supraventricular ectopic beats without structural heart disease. The study will evaluate the reduction of the number of supraventricular ectopic beats and symptoms related.
This trial evaluates the safety and effectiveness of catheter ablation for PAF. The investigational catheter being studied is the NAVISTAR® THERMOCOOL® irrigated-tip catheter. At the time of this study, the NAVISTAR® THERMOCOOL® Catheter was FDA-approved for commercial distribution in the U.S. for treating patients with Type I atrial flutter and drug refractory monomorphic sustained ventricular tachycardia post myocardial infarction. The catheter was approved for use in Europe for endocardial ablation for treating cardiac arrhythmias.
The purpose of this study is to assess the effectiveness of a 10 week program of Stress Management versus control Patient Education sessions on cardiac responses to mental stress in veterans with Implantable Cardioverter-Defibrillators
This is a research study to evaluate the electrical properties of heart tissue. The purpose of this study is to determine the impedance (electrical resistance) of different tissues on the outer surface of the heart. This may be important for distinguishing scarred heart muscle from fat that can be seen on the surface of the heart. This information may eventually be utilized in patients that undergo a procedure (called catheter ablation) for the treatment of life-threatening heart rhythms. Investigators expect a detectable difference between the impedance of normal and infarcted myocardium (approximately 50 ohms).
Radiofrequency ablation is a procedure done in the Catheterization Laboratory to help correct specific problems that cause the heart to beat faster than it should. Quality of life includes the physical as well as the emotional aspects of a patient. Doctors have always tried to take care of a medical problem with minimal physical and emotional risk. It is assumed that once the medical problem is fixed, the patient will have an improved quality of life. To know if this assumption is true, the investigators are asking children scheduled for this procedure, along with their family, to answer questions before the ablation, then answer the same questions 5-6 months after the ablation.
The purpose of this study is to learn the effects of a test drug on heart rhythms, which may become life-threatening if left untreated, and to provide data to see if the drug is well tolerated and safe.
