The Lancet: Remote Monitoring Can Save ICD and CRT-D Patients' Lives

BIOTRONIK Home Monitoring Reduces Mortality and Improves Clinical Outcomes in Patients with Heart Failure

(PresseBox) (Berlin, Germany, ) BIOTRONIK, a leading manufacturer of cardiovascular medical technology, announced the publication of the IN-TIME study results in the medical journal The Lancet today.1 The randomized, controlled trial is the first worldwide to demonstrate that automatic, implant-based remote monitoring leads to significant clinical benefits for heart failure patients. IN-TIME results show how BIOTRONIK Home Monitoring® enables physicians to detect worsening heart failure at an early stage, facilitating early intervention and improved clinical outcomes.

Home Monitoring reduced all-cause mortality by over 50 percent. Clinical status was also significantly improved. Only 18.9 percent of patients using Home Monitoring experienced the worsening of heart failure, compared to 27.2 percent in the control arm (p=0.013). Patients implanted with cardioverter defibrillators and cardiac resynchronization therapy defibrillators (ICDs and CRT-Ds) benefited equally from Home Monitoring.2 Patients with a known history of atrial fibrillation especially benefited from Home Monitoring.3

The BIOTRONIK-sponsored, prospective study randomized 664 patients with chronic heart failure, NYHA class II or III symptoms, ejection fraction ≤35 percent, and optimal drug therapy in groups with or without telemonitoring in a 1:1 ratio. Two hundred and seventy-four patients received an ICD and 390 patients received a CRT-D in adherence with European guidelines, and were followed for one year. The primary outcome, worsening heart failure, was based on a composite score including death, hospitalization, NYHA class and patient self-assessment. Secondary outcomes included all-cause mortality and hospitalization.

"Reducing mortality by over 50 percent is an excellent outcome for any therapy. IN-TIME showed how important automatic, daily transmissions of clinical and device data are to patient management and outcomes," explained coordinating investigator Dr. Gerhard Hindricks, University of Leipzig Heart Center, Germany. "Improvements in patients' health are likely due to the early detection of the onset or progression of ventricular and atrial tachyarrhythmias and the early recognition of therapy settings that may need adjusting."

Home Monitoring transmissions proved reliable, occurring on 85 percent of days per patient year. Medical staff reacted quickly to events. The median reaction time after remote monitoring alert was one day to patient contact and two days to follow-up.

"The effects of Home Monitoring depend on physicians' and medical staff's response to the remotely monitored data. By reacting quickly to notifications, we were able to follow up with patients exactly when they needed medical attention, and adapt their therapy accordingly," said Dr. Peter Sogaard, Aalborg University Hospital, Denmark.

"We were also able to divide work between a qualified nurse and myself, the overseeing physician, to improve our clinic's workflow and ensure efficient patient management."

Heart failure affects approximately ten percent of adults aged 70 or older worldwide.4 The European Society of Cardiology estimates that in Europe alone, at least 15 million people suffer from heart failure.5 An increasing number of patients are being treated with cardiac devices that include some type of remote monitoring technology. The European Society of Cardiology has recently recommended remote monitoring of cardiac device patients for the early detection of clinical events and technical issues.6

About BIOTRONIK Home Monitoring

BIOTRONIK Home Monitoring transmits patient and device data automatically and on a daily basis, thereby rapidly detecting deterioration in a patient's clinical status. The occurrence of atrial or ventricular arrhythmias or specific trends in certain clinical parameters can often be the first sign of worsening heart failure leading to hospitalization or death. Early detection of these clinically relevant events, in particular asymptomatic atrial fibrillation, enables the physician to adapt patient therapy at a very early stage. Home Monitoring effectively supports the management of heart failure patients.
