Evolution of Management Strategies of Heart Failure Patients With Implantable Defibrillators

Heart failure patients with implantable defibrillators (ICD) perform frequent clinic visits for routine device monitoring. Moreover, in case of clinical events, such as ICD shocks or alert notifications for changes in cardiac status or safety issues, they often visit the emergency department or the clinic for an unscheduled visit. These ...

Pilot Study: Hypovitaminosis D Hyperparathyroidism and Hypomagnesemia in Patients With Congestive Heart Failure

People with heart failure may have low magnesium and low vitamin D levels. They may also have abnormally high levels of parathyroid hormones. Magnesium and vitamin D are important chemicals that are not routinely measured in blood tests. We are studying how many people with heart failure have low levels ...

Phase N/A

Prevalence of Atrial Delay That Would Preclude Optimization of Atrioventricular (AV) Delay in Patients With Biventricular (BiV) Device

This is a prospective observational study. Patients referred for BiV-ICD implantation or upgrade will be implanted as is routinely done, with the following modifications: - Electrical readings will be taken at various points in the procedure. - The RA lead will temporarily be placed on the atrial septum for these ...

Phase N/A

Metabolic Changes in Patients With Chronic Cardiopulmonary Disease

This study aims to evaluate prevalence of sarcopenia and cachexia in patients with chronic cardiopulmonary disease. The investigators will also investigate metabolic disorders like glucose metabolism, presence of metabolic syndrome, body composition and histological changes in skeletal muscle and body fat. Finally, patients will be followed for clinical endpoints.

Phase N/A

Procedures and Follow-up of Percutaneous Tracheostomy in Intensive Care Unit

Tracheostomy is worldwide performed in Intensive Care Unit (ICU). According to the current literature, indication for percutaneous tracheostomy (PDT) in ICU are: difficult prolonged weaning, prolonged mechanical ventilation, loss of airway reflex, copious secretions, upper airway obstruction. Many studies have focused on the comparison between different PDT techniques and complication. ...

Implantable Cardioverter Defibrillators And Magnetic Resonance Imaging of the Heart at 1.5 Tesla

The presence of an implantable cardioverter defibrillators (ICD) is currently considered an absolute contraindication to MR imaging, and most patients with PM are excluded from having MRI. As a result from studies such as MADIT I, MADIT II, SCDHeft etc. the number of patients with ICDs has been continuously growing ...

Phase N/A

Insulin Resistance : Heart Failure

There is increasing evidence of a reciprocal interrelationship between chronic heart failure (CHF) and insulin resistance (IR). Studies have shown that patients with CHF have IR and that the degree of IR is associated with reduced exercise capacity and peak oxygen consumption (VO2). IR has also been linked to decreased ...

Phase N/A

Does Lung Impedance Correlate With Changes in BNP in Stable and Acutely Decompensated Heart Failure Patients?

This is a prospective non-randomized longitudinal study. One hundred subjects will participate in 6 monthly and 3 bi-monthly serial assessments of plasma-based BNP, implantable device measured intrathoracic impedance, and clinical evaluation of heart failure status. Each patient will be enrolled in the study for a period of 12 months.

Phase N/A

Treatment of Cheyne Stocks Respiration With Adaptive Servo Ventilation and Bilevel Ventilators in Patients With Chronic Heart Failure

The overall purpose of this study is to determine the effects of adaptive servo ventilation (ASV) and bi-level ventilators on Cheyne-Stocks respiration (CSR). CSR is a pattern of breathing characterized by hyperpneas followed by hypopneas and or apneas. Clinically, the physiologic changes translate to sleep fragmentation, excessive daytime sleepiness, reduced ...


Prospective Observational Study of the ICD in Sudden Cardiac Death Prevention

PROSe-ICD is a multicenter prospective cohort study of patients who undergo ICD implantation for primary prevention of SCD, designed to compare patients who sustain SCD (as measured by an appropriate ICD firing for rapid VT or VF) to those who do not. The cohort for this observational study consists of ...
