CorVue algorithm efficacy to predict heart failure in real life: Unnecessary and potentially misleading information?

Abstract

CorVue™ showed a low sensitivity to predict HF events. Therefore, routinely activation of this algorithm could generate misleading information.

A Steep Increase in the HeartLogic Index Predicts COVID-19 Disease in an Advanced Heart Failure Patient

“…However, these devices also increasingly allow for device-based telemonitoring of the patient's disease state, especially for heart failure. Older examples of these kinds of applications are OptiVol and CorVue [4,5]. Recently, Heart-Logic emerged as a potent predictor of impending heart failure decompensation [6][7][8][9][10][11].…”

Remote Monitoring of Heart Failure in Patients with Implantable Cardioverter-Defibrillators: Current Status and Future Needs

“…The graphic shows seven episodes of congestion with different days of duration (pre-activation state: checked bars) that generated alarms (post-activation state: oblique lined bars) for four of these episodes without an associated clinical event (false positive). Reproduced with permission from Palfy et al (Pacing Clin Electrophysiol, 2018) [ 14 ].…”

Integrated electrophysiology care for patients with heart failure: An envisioned future

“…[10][11][12] Each CIED manufacturer's HF diagnostics are different, and studies demonstrate varying levels of usefulness. [13][14][15][16] However, it is quite clear that prompt identification of device malfunction, new arrhythmias, and inadequate CRT pacing needs to be managed expeditiously. Barriers that prevent patient access to remote monitoring, such as education and telecommunication access, need to be explored and addressed.…”
