2. Brain natriuretic peptide 32 - Wikipedia

   en.wikipedia.org/wiki/Brain_natriuretic_peptide_32

   The main clinical utility of either BNP or NT-proBNP is that a normal level helps to rule out chronic heart failure in the emergency setting. An elevated BNP or NT-proBNP should never be used exclusively to "rule in" acute or chronic heart failure in the emergency setting due to lack of specificity [dubious – discuss]. [19]

3. N-terminal prohormone of brain natriuretic peptide - Wikipedia

   There is no level of BNP that perfectly separates patients with and without heart failure. [14]In screening for congenital heart disease in pediatric patients, an NT-proBNP cut-off value of 91 pg/mL could differentiate an acyanotic heart disease (ACNHD) patient from a healthy patient with a sensitivity of 84% and specificity of 42%. [15]

4. Heart failure - Wikipedia

   en.wikipedia.org/wiki/Heart_failure

   Heart failure (HF), also known as congestive heart failure (CHF), is a syndrome caused by an impairment in the heart's ability to fill with and pump blood.. Although symptoms vary based on which side of the heart is affected, HF typically presents with shortness of breath, excessive fatigue, and bilateral leg swelling. [3]

5. Natriuretic peptide - Wikipedia

   en.wikipedia.org/wiki/Natriuretic_peptide

   B-type natriuretic peptide (BNP) and its pro hormone NT-proBNP are especially useful in diagnosing heart failure, as their levels in the blood increase along with the severity of the condition. [3] Rapid testing of BNP and NT-proBNP can also help distinguish between shortness of breath due to heart and lung-related causes.

6. Heart failure with preserved ejection fraction - Wikipedia

   en.wikipedia.org/wiki/Heart_failure_with...

   Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure in which the ejection fraction – the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled – is normal, defined as greater than 50%; [1] this may be measured by echocardiography or cardiac catheterization.

7. Cardiac marker - Wikipedia

   en.wikipedia.org/wiki/Cardiac_marker

   Pro-brain natriuretic peptide: This is increased in patients with heart failure. It has been approved as a marker for acute congestive heart failure. Patients with < 80 have a much higher rate of symptom-free survival within a year. Generally, pt with CHF will have > 100.
