What is heart failure?
|
when the cardiac output is not meeting the needs of the body and results when heart disease is severe
|
|
|
Which type of hypertrophy is caused by volume overload?
|
Eccentric
caused by PDA and mitral valve disease |
|
|
What type of hypertrophy is caused by pressure overload?
|
concentric
caused by aortic stenosis and VPDs |
|
|
When should an animal with heart failure be treated at the hospital?
|
when the animal has severe pulmonary edema with profound respiratory distress
supplement with oxygen and IV drugs |
|
|
What drug can you use to reduce the stress of animals with heart failure in the hospital?
|
Butorphanol
|
|
|
What can you used to help place a nasal catheter and what is the dose of O2 used?
|
lidocaine gel using 50-100% O2
|
|
|
When is it necessary to used ventilatory support in patients with heart failure?
|
in patients that can not maintain a PaCO2 less than 60mmHg
|
|
|
What is the most important drug in the treatment of congestive heart failure?
|
furosemide
activates RAAS |
|
|
How do you know if furosamide is working?
|
you see a reduced respiratory rate
|
|
|
How does furosemide help with congestive heart failure?
|
-increases cardiac output
-reduces distance oxygen travels to reach blood in the lungs *animals can get dehydrated (lower dose) |
|
|
How is heart failure treated?
|
furosamide
oxygen Nitroglycerine sedation |
|
|
What will help reduce the amount of furosemide?
|
-reduced sodium in diet
-ACE inhibitors |
|
|
What can occur with months of therapy with ACE inhibitors?
|
angiotensin escape
can use spirolactone and angiotensin receptor blockers |
|
|
What drugs increase cardiac contractility?
|
Dobutamine -CRI
Digoxin - narrow safety margion and increases Ca influx Pimobendan - uses Ca more efficiently |
|
|
What heart problems is Pimobendan commonly used?
|
DCM or mitral valve insufficiency
|
|
|
Why are fluids a caution in heartfailure?
|
excess fluid can end up in the lungs
give sub-q to allow for body to adapt |
|
|
How much sodium should an animal with congestive heart failure receive in a day?
|
13mg/kg/day or 100g dry food matter
|
|
|
What are examples of beta blockers?
|
Carvedilol and metroprolol
they block catecholamines |
