Congestive Heart Failure Flashcards
(20 cards)
Which 3 drugs are responsible for cardiac remodeling?
Ang II
Aldosterone
Norepi
Which 3 drugs slow cardiac remodeling?
Spironolactone
ACE Inhibitors
ARB’s
The majority of heart failure patients will require the loop diuretic…..
furosemide
If the patient is allergic to furosemide, then give them what?
Ethacrynic Acid
Which types of diuretics cause hypokalemia?
Which diuretics can help reduce the hypokalemia caused by the above?
Loop and Thiazides
Potasssium Sparing Diuretics (Spiro)
Advanced heart failure patients are given ACE inhibitors and diuretics, what else can be added to help patiets survive longer?
Spironolactone
What are the 3 most important basis for use ACE inhibitors in HF?
Reduction in arterial resistance (afterload)
Reduction in venous tension (preload)
Slows down cardiac remodeling
ACE inhibitors work to help reduce cardiac modeling in ….systolic or diastolic HF?
Systolic
Which ACE inhibitor can significantly reduce LV hypertrophy?
Enalapril
What is the advantage of using an ARB as opposed to an ACE Inhintor?
THe ARB will not produce a cough, because it is not involved wth Bradykinin
Which 4 Beta blockers are used to help trear CHF?
What is the specific pathology involved for its treatment?
Carvedilol, Metoprolol, Bisoprolol, and Atenonlol
Dilated Cardiomyopathy (Systolic Dysfunction)
What are the 3 main categories for vasodilators?
Nitrates
Hydralazine
Sodium nitroprusside
What are some inotropic drugs?
Digoxin (cardiac glycoside), Dobutamine (Beta agonisr),
Amrinone, and Milrinone (PDE inhibtors)
What are the two things Digoxin do to treat CHF (systolic) ?
Increase contractility
Enhance Vagal tone
Whats the benefit of Digoxin enhancing vagal tone?
to slow down sinus heart rate and av conduction
*to reduce the rapid vetricular rate in atrial flutter and fibrillation*
What is the first sign of Digoxin toxicity?
Vision issues (abnormalities in color vision)
What 3 physiological factors increase digoxin toxicity?
hypokalemia
hypercalcemia
hypomagnesemia
Which 3 drugs can enhance digoxin toxicity?
quinidine, amiodarone, verapamil
In digoxin toxicity, serious arrhythmias can occur, which 3-4 drugs can help treat it?
lidocaine/phenytoin (ventricular arrhythmias)
atropine (av block)
digoxin specific antibody fragments (given IV for severe OD)
