Ohio Tests Wireless Heart Failure Monitoring System
With millions of Americans hospitalized each year due to heart failure, The Ohio State University Medical Center is testing the safety and effectiveness of an implanted, wireless pressure sensor as part of a pivotal clinical study that may allow for more rapid intervention by cardiologists in treating these patients.
“The device provides real-time access to critical information at any time,” says Dr. William Abraham, director of the division of cardiovascular medicine at Ohio State’s Medical Center and the trial’s co-principal investigator. “The study will help determine if physicians can use this data to assist in identifying the appropriate medical treatment for heart failure patients.”
The device is implanted in the patient’s pulmonary artery using a simple, catheter-based procedure. Pulmonary artery pressure is then measured and transmitted to a secure website, where it is available for review by the implanting physician. The data is also available to the physician on a handheld computer, such as a PDA, any time around the clock.
OSU Medical Center has implanted 10 patients to date as part of a feasibility study and ongoing CHAMPION trial, which is sponsored by CardioMEMS, Inc., Atlanta, Ga. Dr. Ayesha Hasan, a heart failure cardiologist at Ohio State’s Richard M. Ross Heart Hospital, is the study’s lead principal investigator at Ohio State. Abraham is a paid consultant for the company, and Hasan has received research support from the company.
