Heart Headlines for Heart Month: Sentara Cardiovascular Research Institute Investigates System Designed as Early Warning for Heart Failure Patients

--Investigational device designed to alert patients before symptoms of heart failure occur--

NORFOLK, Va., Feb. 28, 2012 /PRNewswire-USNewswire/ -- Researchers at Sentara Cardiovascular Research Institute are among the top enrollers among 69 leading heart centers in the U.S. involved in a clinical trial designed to use a new investigational device to evaluate the safety and efficacy of a physician-directed patient self management system.

The purpose of the study is to determine if an implantable device, smaller than a smart phone, can effectively monitor the pressure in the left atrium of the heart, and manage the patient's medications to reduce episodes of heart failure.

Heart failure is a chronic condition in which the heart is not pumping as well as it should. Clinicians commonly use the symptoms of heart failure such as fatigue or shortness of breath to determine a heart failure patient's status and need for treatment. Left atrial pressure is considered an excellent indicator of status, providing the most objective measure. Changes in left atrial pressure occur before fluid retention and worsening of heart failure symptoms.

In this research study, the device is implanted just under the skin in the chest with wires connected to the heart in half of the study patients. This device records left atrial pressure, and a hand-held monitor collects that information, transmits the information to doctors and nurses at the study center over regular phone lines, and directs patients to take medicines or make lifestyle changes as needed. The study is designed to ask patients to increase heart failure medicines to relieve symptoms before they occur.

The study (called Left Atrial Pressure Monitoring to Optimize Heart Failure Therapy (LAPTOP-HF) is designed to evaluate the rate of heart failure episodes and hospitalizations among the treatment group of heart failure patients and the control group.

"We want to find the body's earliest warning of a heart failure episode even before a patient feels bad or exhibits classic signs of distress like swelling. Our hope is to be able to treat these patients at home, well before a patient needs to come to the hospital," says cardiologist John Herre, M.D., principal investigator and co-medical director at Sentara Cardiovascular Research Institute.

According to the American Journal of Cardiology in January 1999, heart failure affects about 4.5 million people in the U.S. and about 75 – 80 percent of these patients are more than 65 years old.  Heart failure accounts for more than 11 million doctor's visits and 3.5 million hospitalizations per year. Annually, it is estimated that heart failure costs $25-40 billion. The estimates do not include indirect costs such as loss of productivity.

About LAPTOP-HF

The Left Atrial Pressure Monitoring to Optimize Heart Failure Therapy (LAPTOP-HF) is a randomized, controlled study sponsored by medical device company St. Jude Medical. This study is currently enrolling patients at 69 sites around the U.S with a goal to enroll a total of 730 patients. Sentara is among the top enrolling heart centers in the country for the study.  Participants are 18 years or older, have congestive heart failure, are taking related medications and have experienced at least one hospitalization within 12 months or have a chronically elevated BNP level.  Participation in the study lasts about five years.  For more information about the study and eligibility, visit www.clinicaltrials.gov . The study identifier is NCT01121107.
