Tiny sensor in lung artery could keep heart failure patients out of hospital

This study is testing whether a small wireless sensor placed in the lung artery can help doctors manage heart failure better. The sensor measures pressure in the lung artery and sends readings to a doctor, who can then adjust medications early to prevent flare-ups. The study will enroll 1000 people with heart failure who have had a recent hospital stay or high blood markers. Half will get the sensor plus standard care, and half will get standard care alone. Researchers will compare how often each group ends up in the hospital and how long they live.
