All of the following correctly describe heart failure EXCEPT:
a) Heart failure has many causes including myocardial infarction and valve defects.
b) Heart failure is typically associated with an increase in pressure within the ventricle.
c) Heart failure is characterized by decreased cardiac output and the inability of the heart to supply adequate oxygen to peripheral tissues and organs.
d) Coronary artery disease (hardening and narrowing of coronary arteries) restricts blood flow to the cardiac muscle and can cause ischemia, angina, and damage to heart tissue damage.
e) Low blood levels of B-type Natriuretic Peptide are associated with severe heart failure.
f) Heart failure can lead to pulmonary hypertension and congestion in the lungs.
