Overview

The Collaborative Group on ACE Inhibitor Trials demonstrated significant reduction in total mortality and hospitalization with the administration of ACEIs that was consistent among wide range of patients.

ACE Inhibitors

Indications for ACE Inhibitors Use

1. The left ventricular ejection fraction (LVEF) is ≤ 40%

or

2. There is a prior history of myocardial infarction (MI)

Background

• ACE-I or ARB therapy is recommended for ANY patient with reduced left ventricular ejection fraction (≤ 40%) regardless of the etiology of left ventricular systolic dysfunction (ischemic or nonischemic) or presence/absence of symptoms. Patients with or without heart failure (in other words, even those with asymptomatic left ventricular systolic dysfunction) are included in this recommendation.
• In addition, ACE-I or ARB therapy is indicated for patients with history of myocardial infarction whether or not left ventricular systolic dysfunction or heart failure is present.
• ACE-I or ARB therapy is also recommended for patients who are at high risk for the development of heart failure due to the presence of coronary, cerebrovascular, or peripheral vascular disease.
• Treatment should not be deferred in patients with few or no symptoms because of the significant mortality benefit derived from ACEI therapy.

Dosing

• ACE-I or ARB therapy should be initiated at low dosage such as 12.5 mg tid of captopril, 2.5 mg bid of enalapril, or 2.5 mg daily lisinopril.
• Every 4 to 6 weeks the dose is gradually uptitrated, as tolerated, toward target dosages of 20-40 mg daily for lisinopril, 10-20 mg twice daily for enalapril maleate, and 50-100 mg three times a day for captopril, or to the maximum tolerated dosage.
• ACE inhibitors are rarely adequate for the treatment of congestion without the use of diuretics.

Complications

• 5-10 % patients cannot tolerate ACE inhibitors because of cough. Cough can be a sign of elevated left-sided filling pressures or a side effect of ACE inhibitors due to excess bradykinin.
• ARBs are reserved for patients who are intolerant of ACE-Is for reasons (such as persistent cough) OTHER than hyperkalemia, progression of chronic kidney disease/worsening azotemia, or hypotension caused by prior ACE-I therapy. If a patient experiences hyperkalemia, worsening azotemia, or hypotension as a result of ACE-I therapy, the same is likely to result from ARB therapy. In the CHARM study candesartan reduced both hospitalization and mortality.
• Renal artery stenosis should be considered if there's a decline in renal function with the initiation of ACE inhibitors.

Angiotensin-Converting Enzyme Inhibitors in Patients Presenting With Heart Failure (DO NOT EDIT)

Class I

"1. The use of ACE inhibitors is beneficial for patients with prior or current symptoms of chronic HFrEF to reduce morbidity and mortality (Class I, Level of Evidence: A)"

Class III (No Benefit)

"1. Routine combined use of an ACE inhibitor, ARB, and aldosterone antagonist is not recommended for patients with current or prior symptoms of heart failure and reduced left ventricular ejection fraction (LVEF). (Level of Evidence: C) "
