cardiac disease - session 6 Flashcards
What is the most common heart disease diagnosed in dogs in GP?
1 cardiomyopathy is DCM
Mitral valve disease
Best clinical finding to differentiate cardiac from non-cardiac causes of respiratory distress in this cat?
In cats, B - a positive BNP or high BNP result correlates well with congestive heart failure.
Does lack of a heart murmur help differentiate between non-cardiac and cardiac causes of respiratory distress in cats?
YES
lack of a heart murmur does provide evidence of non-cardiac cause of respiratory distress in cats
Does lack of a heart murmur help differentiate between non-cardiac and cardiac causes of respiratory distress in dogs?
SIGNALMENT MATTERS!!!
In an older, small breed dog (valvular disease more common), the lack of a murmur DOES make a non-cardiac cause of respiratory distress much more likely.
In a large breed predisposed to DCM, presence or absence of a murmur does NOT help differentiate between cardiac and non cardiac
In patients with pulmonary edema secondary to left-sided congestive heart failure, what therapeutic intervention will help restore blood oxygen levels the QUICKEST?
administer flow by O2
By increasing the partial pressure of oxygen at the alveoli, more oxygen will be driven over into the blood stream and this will be the quickest way to increase blood oxygen levels.
V/Q mismatch!
What is the best way to treat a patient who on Furosemide for CHF but is showing signs of dehydration?
The best choice for a cat who is in acute CHF would be to continue the furosemide at a reduced dose or frequency, and the safest thing would be to allow the patient to rehydrate enterally.
**Giving IV fluids or SQ fluids in a patient in CHF is not recommended
Why should you use and ACE inhibitor or an MRA with furosemide in patients with CHF?
Furosemide can induce the RAAS system causing inc workload on the heart
Why is moderate salt restriction recommended in patients (who are eating well!) in Stage C and Stage D heart disease?
High sodium intake can cause diuretic resistance and contribute to body water retention
What defines stage A heart disease
at risk but no evidence of disease
What defines stage B1 of heart disease
evidence of disease but no clinical signs
normal/mild atrial enlargment
What defines stage B2 of heart disease
evidence of disease but no clinical signs
moderate/severe atrial enlargment
What defines stage C of heart disease
current/previous CHF/ATE
What defines stage D of heart disease
on current therapy for CHF but requires additional therapy
