UI seeks participants for heart failure study

A University of Iowa Heart and Vascular Center study seeks adults age 18 and older with heart failure for a clinical trial to evaluate the benefits of a wireless pressure sensor for heart failure. This sensor is being studied to see if it will reduce the number of hospitalizations for people with heart failure.

Eligible participants must have a history of heart failure and have had a heart failure-related hospitalization in the past 12 months.

Participation involves a minimally invasive heart procedure, visits to the UI, and use of the Heart Failure Pressure Measurement System from home. The system, developed by CardioMEMS, Inc., consists of a sensor, delivery system, external electronics (antenna) and a home monitoring unit. The system is used in participants' homes to transmit their pulmonary artery pressure measurements to a secure Web site for the study doctor to review.

For more information contact the UI Cardiomyopathy Treatment Program at 319-356-1028 and ask for Barry Cabuay, M.D., principal investigator for the UI site, or Cynthia Larew. You may also email the Cardiomyopathy Treatment Program at or visit online at
