NBN Infusions delivers comprehensive services to patients of all ages, from pediatric to geriatric, providing a full range of care for Home Infusion Therapy. NBN Infusions on-site, licensed pharmacy can provide prescription medications, equipment, supplies and skilled nursing care needed for Home Infusion Therapy.

Home Infusion Therapy is a more convenient and cost-effective option than traditional inpatient therapy, with care administered in the comfortable surroundings of one’s own home. Home Infusion Therapy allows for a more active role in one’s own health care. It can also ease stress and anxiety that is sometimes associated with inpatient treatment, resulting in better patient outcomes.

 

 

A multidisciplinary team of experts in heart failure, cardiac arrhythmia, and neurosurgery at The Mount Sinai Hospital are now testing nerve stimulation in the neck as a novel therapy for heart failure patients to potentially help relieve their debilitating symptoms of fatigue, shortness of breath, and heart arrhythmias, while reducing their hospitalizations.

 

The global, multicenter randomized clinical trial called INOVATE-HF (INcrease Of VAgal TonE in chronic Heart Failure) is investigating the safety and efficacy of an implantable vagus nerve electrical stimulation device called CardioFit- to improve the heart’s function and the quality of life of heart failure patients.

 

Mount Sinai’s multidisciplinary team of clinical trial investigators includes principal investigator electrophysiologist Vivek Reddy, MD, Director of Arrhythmia Services; neurosurgeon Brian H. Kopell, MD, Director of the Center for Neuromodulation; and heart failure specialist Ajith P. Nair, MD, Director of the Pulmonary Hypertension Program in the Advanced Heart Failure and Transplantation Program.

 

The device is a three-part system consisting of a “stimulator” about the size of a pacemaker, and two connecting leads. The stimulator is implanted under the skin of the chest with a “sensor lead” implanted inside the right ventricle of the heart, and a “stimulation lead” implanted around the vagus nerve in the right side of the neck.

 

The large vagus nerve runs from the brain stem down to the abdomen on both the left and right side of the body. It sends signals throughout the body and directly to and from the brain to regulate multiple bodily functions including heart rate.

 

Once activated by doctors, the stimulator in the chest sends mild electrical pulses up to the vagus nerve to help reduce heart rate, stress, and workload on the cardiac muscle to improve overall heart function. The sensor lead in the heart’s right ventricle monitors for any abnormal changes in the heart’s electrical activity and provides feedback to the stimulator enabling it to react.

 

“This novel use of vagus nerve stimulation may be the therapy we have long been waiting for to bring relief to heart failure patients with chronic symptoms and protect them from dangerous and potentially fatal arrhythmias,” says Dr. Vivek Reddy, Director of Arrhythmia Services at The Mount Sinai Hospital. “The results of this study testing the simple electrical stimulation of the body’s powerful vagus nerve may unlock a future promising therapy for heart failure. I am excited that by working with our heart failure and neurosurgery colleagues, we can offer this potentially transformative therapy to our patients.”

 

“Our clinical trial will compare the benefits of vagus nerve stimulation to the standard treatment of combination medication which is currently our first line of defense against heart failure,” says Dr. Ajith P. Nair, Director of the Pulmonary Hypertension Program in the Advanced Heart Failure and Transplantation Program at The Mount Sinai Hospital. “Our study will also test vagus nerve stimulation therapy’s ability to reduce hospitalization, a major issue for heart failure patients, as well as, its capability to reduce mortality in this high-risk population.”

 

“At Mount Sinai we have successfully used vagus nerve stimulation for refractory epilepsy in patients with uncontrollable seizures, and to treat patients with major depression, who don’t have good responses to medication therapy,” says Dr. Brian H. Kopell, Director of the Center for Neuromodulation at The Mount Sinai Hospital. “This trial represents the first time VNS is being tested in heart failure patients in the United States. We are excited to see what clinical benefits are possible and hope this innovative therapy may bring relief to patients at Mount Sinai and around the world suffering from heart failure.”

 

Recent international studies investigating the CardioFit- device have shown that patients with the nerve stimulation device can experience sustained improvement in heart function and structure, heart rate, improvement in quality of life, and increased exercise tolerance. Research shows patients may start to experience improvement in their heart failure symptoms after several weeks and months of gradually increased nerve stimulation therapy.

 

Heart failure affects more than six million people in the United States and 23 million worldwide. It occurs when a person’s heart is too weak to properly pump and circulate blood throughout their body. A single or several conditions over time can increase a person’s risk of developing heart failure by weakening their heart muscle or damaging their heart’s vessels including arrhythmias, which are abnormal electrical heart rhythm disturbances affecting the heart’s proper beating.

 

Patients eligible for enrollment in the INOVATE-HF clinical trial are those diagnosed with New York Heart Association stage III “moderate” heart failure, who even though they are being treated with several combination medications, they continue to have debilitating symptoms including fatigue, shortness of breath, and abnormal heart arrhythmias.
