Cardiorespiratory and Critical Care - Cardiac Emergencies Flashcards
What side of the heart does myxomatous mitral valve disease originate from?
left side
What breeds are affected by myxomatous mitral valve disease?
small breeds
What sided heart failure is dilated cardiomyopathy from?
left side
What size breeds are affected by dilated cardiomyopathy?
large breeds
What side of the heart is pericardial effusion affected?
Right side
What type of heart failure can young dogs get?
congenital heart disease
What type of congestive heart failure can cats get?
biventricular failure
What type of biventricular heart failure do cats get?
hypertrophic cardiomyopathy
What veins are affected by right sided congestive heart failure?
systemic veins
What direction does ressure go in from the cranial and caudal vena cava?
upwards
What can pericardial effusion be secondary to?
a tumour
What type of failure is left and right sided?
backward
What is forward failure?
reduced cardiac output
What will you see with right or left sided forward failure?
- weak peripheral pulses and tachycardia
What conditions can be caused by left sided heart failure to the lungs?
- pulmonary oedeam
- tachypnoea/dyspnoea
- coughing
Is a cough caused by heart failure of heart disease?
heart disease
How can the body be affected by right sided heart failure?
- distended peripheral veins
- ascites, pleural effusion
What causes weak peripheral pulses?
decreased stroke volume
How is left sided heart failure presented?
- heart murmur
- tachypnoea/dyspnoea
- tachycardia
- pale, prolonged capillary refill time
- arrhythmias?
- weak peripheral pulses, pulse deficits
What common symptom is seen in forward heart failure?
pale mucous membranes
What can be seen with systolic dysfunction?
weak peripheral pulses
What clinical approach can be used with left sided congestive heart failure?
- taking history
- physical exam
- stabilisation before diagnostic testing
Stabilising left sided congestive heart failure?
- minimise stress
- sedation?
- oxygen supplementation
- furosemide IV
- pimobedan PO/IV
What sided heart failure can you give furosemide to?
left and right
What does furosemide do for heart failure?
reduces pressure in the heart and the drive to push fluid out of circulation and into body cavitites
What does pimodendan do?
reduces stroke volume
