Prairie Heart first in area to use new test for congestive heart failure
SPRINGFIELD -- Prairie Heart Institute at St. John's today announced a new test
is being used to aid in the diagnosis of congestive heart failure, a serious and
often fatal heart condition.
The Triage BNP Test is the first blood test to be cleared in the United States as
an aid in the diagnosis of congestive heart failure. It is particularly helpful
in emergency situations when patients are
experiencing shortness of breath. Until now, diagnosis has been difficult because
shortness of breath is a symptom of both chronic lung disease and congestive heart
failure. The test measures circulating
levels of B-type natriuretic peptide (BNP) that are elevated during heart dysfunction
in both early and late-stage congestive heart failure patients. St. John's Hospital
is the first in the area to use the
test.
"Since the introduction of echocardiography in the 1970's, there have been few significant
advancements in diagnosing congestive heart failure," said Dr. Stephen Jennison,
director of the
Heart Failure program at Prairie Heart Institute. "Prior to this test, physicians
relied on x-ray and physical evaluation of these patients, however, the information
was sometimes subjective, resulting in
misdiagnosis of the
disease. This blood test will play an important role in improving early detection of congestive heart failure, enabling physicians to provide more timely treatment of this progressive
disease."
The Triage BNP Test is being used to facilitate accurate diagnosis of patients who
are experiencing shortness of breath or other symptoms associated with heart failure.
The fifteen-minute test
assesses a patient's
status by measuring BNP, which is released by the left ventricle
of the heart when it experiences overload or stress. The resulting loss in pumping
action is viewed as an important clinical determinant in diagnosing congestive heart
failure.
"Patients exhibiting shortness of breath and other symptoms of congestive heart
failure account for millions of emergency room visits in the U.S. each year," said
Dr. Jennison. "Many have several health conditions, making it difficult to determine
which is the source of the problem. When a patient is in distress, time is crucial.
A rapid, quantitative test will help us determine quickly and objectively whether
the problem is attributable to congestive heart failure, thereby leading us to begin
treatment and possibly save lives. This is an especially useful test because it
helps the clinician differentiate between shortness of breath due to chronic lung
disease versus heart disease, as only the
latter will cause a significant rise in the BNP," he concluded.
