MINNEAPOLIS & MUNICH, Germany--(BUSINESS WIRE)--More than 22 million people worldwide suffer from heart failure1, and most heart failure hospitalisations are due to excessive fluid accumulation in the chest cavity. New data presented at the European Society of Cardiology (ESC) Congress shows that Medtronic, Inc. (NYSE:MDT) cardiac devices equipped with OptiVol® Fluid Status Monitoring Alerts™ may give physicians advance warning of their heart failure patients’ worsening condition, thus reducing the rate of heart failure hospitalisations and clinically relevant events. Two year follow-up data, presented by Dr. Maurizio Landolina of Italy, shows this may be as much as a 50 percent reduction. (OptiVol Alerts are currently investigational in the United States.)
