In which patients should ACE inhibitors be used?
Must be used in all who do not have contraindications regardless of etiology or severity of disease
In which patient populations see additional benefits with ACE use?
-IHD
-CKD
-Post-MI
-DM
ACE inhibitor mechanism of action
-Prevents conversion of angiotensin I to angiotensin II
-Blocks the conversion of bradykinin to inactive peptides
Why is it beneficial to block the conversion of bradykinin to inactive peptides?
Allows activation of the bradykinin receptor leading to improved endothelial function
Why is it beneficial to block the conversion of angiotensin I to angiotensin II?
Angiotensin II cause increased afterload disease progression
ACE inhibitor benefit in heart failure
-Improved endothelial function
-Decreased NE
-Inhibition of cardiac hypertrophy
-Improved cardiac hemodynamics
-Reduced aldosterone
-Decreased endothelin-1
-Decreased arginine vasopressin
-Reduced vasoconstriction
-Reduced Na and water retention
Initial dose of enalapril
2.5-5 mg BID
Target dose of enalapril
10 mg BID
Initial dose of captopril
6.25-12.5 mg TID
Target dose of captopril
50 mg TID
Initial dose of lisinopril
2.5-5 mg QD
Target dose of lisinopril
20-40 mg QD
ACE dosing conversions
20 mg E = 150 mg C = 20 mg L
How to dose ACEi
-Titrate dose to target dose
-Start low and double dose every 1-4 weeks
When to be cautious with ACEi use
-Volume depleted
-SBP less than 80
-K over 5
-SeCr over 3
ACEI absolute contraindications
-Pregnancy or intending to become pregnant
-History of angioedema or hypersensitivity
-Bilateral renal artery stenosis
-History of WELL-DOCUMENTED intolerance due to symptomatic hypotension, decline in renal function, hyperkalemia or cough
What to monitor in patients taking ACEi
-Volume status
-Renal function
-Serum potassium
-Blood pressure
-Other adverse effects
