Hypothesis-generating for implantable monitoring in severe CHF; prospective trials needed before clinical adoption.
Pagé et al. (2007) conducted an observational in Congestive heart failure (n=67). Implantable device-based expert system vs. Control group without history of CHF was evaluated on Prediction of adverse medical events (Sensitivity 88%, Specificity 94.7%). An implantable device-based expert system monitoring minute ventilation and activity predicted adverse clinical events in severe CHF patients with 88% sensitivity and 94.7% specificity.
