Biotronik has reported the results of its Home Monitoring in Cardiac Resynchronisation Therapy clinical study. The international, multicentre, non-randomised and prospective study was designed to develop an automated multi-parameter algorithm that will use daily Biotronik Home Monitoring data to dynamically predict death and hospitalisation. The prediction is based on cardiovascular factors, including mean heart rate, patient activity, and heart rate variability, which are used to analyse the cardiovascular status of heart failure patients. The combination of all parameters resulted in 65.4 percent sensitivity in detecting cardiovascular hospitalisations and deaths with 99.5 percent specificity. Coordinating clinical investigator Stefan Sack said that he believes that combining several parameters into a single algorithm may improve the overall ability to risk-stratify patients with implanted cardiac devices.
