Mercy Offers Patients a New Heart Failure Monitoring Solution

June 30, 2015

ST. LOUIS – More than 5 million Americans have heart failure (HF), with more than a half million new cases diagnosed each year. In addition, heart failure is one of the leading causes of hospital readmissions.

To improve the quality of life and keep HF patients out of the hospital, Mercy Hospital St. Louis is one of the first centers in the region offering CardioMEMS™ HF System. CardioMEMS™, a miniature, wireless monitoring sensor implanted in the pulmonary artery during a minimally invasive procedure. The new system measures pulmonary artery (PA) pressure – an early indicator of worsening HF – even before a patient notices symptoms such as shortness of breath or weight gain.

“CardioMEMS allows our team to provide personalized and proactive care for our heart failure patients,” said Dr. Bruce Czarnik, cardiologist and board-certified heart failure specialist with Mercy Clinic Heart and Vascular. “Since we can catch issues early, we’re able to keep our patients at home and out of the hospital.”

The CardioMEMS sensor is designed to last the lifetime of the patient and doesn’t require batteries. Once implanted, the wireless sensor sends pressure readings to an external patient electronic system. There is no pain or sensation for the patient during the readings. It transmits critical information about a patient’s HF status to a clinician on a regular basis, without the need for additional clinic or hospital visits. This provides clinicians the ability to detect worsening HF sooner and adjust treatment to reduce the likelihood the patient will need to be hospitalized.

Data from the Champion trial showed the CardioMEMS technology reduces heart failure hospital admissions by up to 37 percent. According to the American Heart Association, the estimated direct and indirect cost of HF in the U.S. for 2012 was $31 billion and that number is expected to more than double by 2030.
