Module 5
Cardiovascular and Coagulatio
,Pathophysiology of Heart Failure
Inability of the heart to meet and
maintain the oxygen demands of
the body. Heart failure can be
caused by prolonged hypertension,
myocardial infarction, or damage to
the cardiac muscle. It results in
pump failure, meaning the blood
cannot circulate like it should. This
causes blood to back up in the
circulation

,Diagnostics
▪ BNP (this is one of the best indicators for heart failure!)
▪ Chest Xray
▪ ECG
▪ Hemodynamics
▪ Ultrasound/echo (Ejection fraction less than 40% is concerning)
, BNP
What is a BNP lab for?
Brain natriuretic peptide
(BNP) test is a blood test
that measures levels of
a protein called BNP
that is made by the
heart and blood vessels.
BNP levels are higher than
normal with heart failure.
