“I consider this to be the first
major breakthrough in heart failure management in more than a decade,” Abraham
said. “For the first time, cardiologists can directly manage a patient’s
pulmonary pressures rather than managing their symptoms or weight gain.”
The CardioMEMS HF system is approved
for people with moderate (NYHA class III) heart failure who have had
hospitalizations within the last year. About the size of a large paper clip,
the device is implanted into the pulmonary artery using a simple catheter-based
procedure. It takes real-time measurements of pulmonary artery pressure and
transmits them to a secure website where doctors can review the data and make
medication adjustments, if needed.
“An increase in pulmonary artery
pressure is the most direct sign of congestion,” Abraham said. “By identifying
these elevated pressures early, we can treat patients before they get sick and
avoid episodes that lead to repeated hospitalizations.”
Results from studies show the
monitor has reduced hospital readmissions by 37 percent, when compared to
standard care. The study also determined the device to be safe and cost-effective,
with implant procedures costing approximately $15,000 or roughly the same cost
as one average hospitalization for heart failure.
Nearly 5 million Americans have heart failure
and it’s often under recognized. Symptoms can be mistaken for normal signs of
aging. They include: shortness of breath, even during mild activity; difficulty
breathing when lying down; weight gain with swelling in the legs and ankles
from fluid retention; fatigue and weakness.
Dr. Ayesha Hasan, director of the cardiac
transplant program at Ohio State’s Richard M. Ross Heart
was the lead principal investigator at Ohio State and did today’s implant
“I’ve seen several patients in the clinical
trials go from numerous hospitalizations down to zero. Now with federal
approval, we’re excited that many more people with heart failure can have the
monitor and a better quality of life,” Hasan said.
Next, Abraham says he is planning follow-up
studies to evaluate the long-term effects of the monitoring system.
