Chapter 20: Drugs for HF + other stuff Flashcards
What signs and symptoms are a primary result of in acute heart failure?
pulmonary edema due to elevated LEFT cardiac output
What is a new onset of AHFS is tachycardia due to?
Strong sympathetic response
What are 4 non-drug treatments for HF
Reduce sodium—DASH DIET
Fluid restrictions (2-3L)
Weight management (BMI)
Exercise
What drug improves contractility and pumping ability of the heart. It increases force of contraction by inhibiting sodium, potassium, adenosine triphosphate. Calcium enters the cell In exchange for sodium, which increases contractility
Digoxin
When do you not give Digoxin?
If heart rate is less than 60 do not give.
What do Inotropes (Cardiac Glycosides) indirectly stimulate?
Vagus Nerve
What is first-line drug for those those first diagnosed with HF- cardiac function
Inotropes (Cardiac Glycosides)
When are Inotropes (Cardiac Glycosides) contraindicated? (4)
patients with severe myocarditis, ventricular tachycardia, ventricular fibrillation
What is the therapeutic serum digoxin level is ***??? in Inotropes (Cardiac Glycosides)
0.8-2.0ng/mL
What is a drug that increases CO and decreases preload?
Thiazide diuretic:
With what drug do you want to weigh patient daily?
Loop diuretics
What drug decreases edema in patients with HF?
Aldosterone Antagonist- potassium sparing diuretic
What drug blocks conversion of angiotensin 1 to production of angiotensin 2?
Angiotensin Converting Enzyme (ACE)
Enalapril (Vasotec)
What drug suppress the SNS and the resulting catecholamine excess that eventually damages myocardial cells
Beta blockers
What drug causes vasodilation by exerting direct relaxant effect on vascular smooth muscle, decreasing both preload and afterload
Cardiotonic- Ionotropic Agents
Prototype: Milrinone lactate (Primacor)
