Clinical Approach to Cardiology Flashcards
what might prompt you to look for heart disease in an asymptomatic animal?
murmur
arrythmia
gallop
high-risk animal
planning to stress heart
breeding
what tests are available for occult heart disease in dogs?
thoracic radiographs
biomarkers
ECG
point-of-care-echo
echocardiogram
what should you look at on thoracic radiographs for heart disease?
heart size
pulmonary vasculature
pulmonary parenchyma
pleural space
when should you prescribe pimobendan in an asymptomatic dog with only thoracic radiographs?
VHS > 11.5v
VLAS > 3v
what value of NT-proBNP is abnormal in most dogs?
> 900 pmol/L
what drug can you give for both ventricular and atrial arrythmias?
amiodarone
what can you use point-of-care echo to look at?
left atrial size
left ventricular size and function
pericardial or pleural effusion?
what is the most common canine heart disease?
degenerative mitral valve disease
what is stage A of degenerative mitral valve disease?
high risk for developing heart disease but currently have no identifiable structural disorder of the heart
