Economic evaluation of Cardiac Contractility Modulation (CCM) therapy with the optimizer IVs in the management of heart failure patients

چکیده
Heart failure (HF) is a complex clinical syndrome caused by structural and/or functional cardiac disorders that impair the heart’s ability as a pump to support the circulation1-3. It is associated with a broad spectrum of signs and symptoms resulting in a wide range of clinical expressions. Its prevalence is approximately 1-2% of the population and increases rapidly with age, reaching double digits in those above the age of sixty five4-7. Hence, due to the aging of the population and the improved survival of patients presenting with acute coronary syndromes, the number of HF patients is constantly rising. People with HF exhibit high mortality rates and very poor quality of life, both of which are comparable to or even worse than that of many cancer patients. Moreover, HF patients are hospitalized very frequently and they consume significant amount of healthcare resources8-10. Therefore, HF represents a significant cost burden for health systems and a considerable cause of productivity loss for society5-7.

First use of cardiac contractility modulation (CCM) in a patient failing CRT therapy: clinical and technical aspects of combined therapies.
Cardiac contractility modulating (CCM) signals delivered by the OPTIMIZER System are being investigated as a treatment for medically refractory heart failure. Previous chronic studies of CCM have excluded patients with prolonged QRS and a cardiac resynchronization therapy (CRT) device. However, symptoms persist in more than 25% of these CRT patients. CCM may offer a therapeutic option for these...

BACKGROUND Previous studies in patients and in dogs with experimentally induced heart failure (HF) showed that electrical signals applied to the failing myocardium during the absolute refractory period improved left ventricular (LV) function. We examined the effects these same cardiac contractility modulating (CCM) electrical signals on myocardial oxygen consumption (MVO(2)) in both patients an...

Cardiac resynchronization therapy (CRT) is an established therapy for patients with systolic dysfunction, QRS duration greater than 120 ms, and New York Heart Association (NYHA) class III or IV symptoms. However, most patients with heart failure have QRS duration below 120 ms and 30% or more of CRT recipients are nonresponders. Cardiac contractility modulation (CCM) signals are nonexcitatory el...
متن کاملCardiac contractility modulation therapy: Are there superresponders?
Introduction Heart failure (HF) is a common cardiovascular disease, and it is associated with high morbidity and mortality despite advances in medical and device-related management. Patients with HF with low left ventricular ejection fraction (LVEF) and narrow QRS complexes represent a special challenge, as they are not candidates for cardiac resynchronization therapy (CRT). These patients may ...
متن کاملCardiac contractility modulation in patients with advanced heart failure.
Cardiac contractility modulation (CCM) is a novel device-based therapy for heart failure that involves applying electrical signals during the absolute refractory period of the myocardial action potential. This therapy has been shown to augment the strength of left ventricular contraction independent of myocardial oxygen consumption in animal models as well as human studies of patients with hear...
