Question:
BNP
Answer:
A cardiac neurohormone secreted by ventricular myocytes in response to
increased wall stretch and pressure
Question:
Clinical indications for order BNP
Answer:
-unexplained dyspnea
-serial measurement in chronic HF aid prognosis
-hospitalized HF - admission & pre d/c levels guide planning
-can be used as early detection for high-risk pts
,Question:
Low levels of BNP
Answer:
strongly argues AGAINST HF
Question:
Elevated levels of BNP
Answer:
supports HF diagnosis but is not specific
-also elevated in ACS, A-fib, renal failure, PE, sepsis
Question:
High levels of BNP in HF
Answer:
-associated w/ worse prognosis, severe dz, high risk of mortality and
hospitalization
Question:
BNP confounders, increases levels
Answer:
Age, renal dysfunction, noncardiac illness (acute/chronic).
,Question:
BNP confounders, decreases level
Answer:
obesity
Question:
BNP and NT-proBNP
Answer:
are not interchangeable - interpret according to specific assay cutoffs and
clinical context
Question:
Infective endocarditis essentials of diagnosis
Answer:
-fever
-underlying valvular dz or prosthetic endovascular material
-positive blood cultures
