Scope of Heart Failure
• Heart failure (HF) is a major public health problem resulting in substantial morbidity, mortality, and healthcare expenditures
• Despite available effective treatments, a large number of eligible patients are not receiving optimal care
• Even with conventional therapy patients remain at risk for disease progression and adverse outcomes

ACC/AHA HF Guidelines 2013:Management of HFrEF (Stage C)
Life-Prolonging Medical Therapy• ACE inhibitors or ARB (Class I, evidence A) in all patients
without contraindications or intolerance.
• Evidence-based beta-blockers (Class I, evidence A) in all patients without contraindications or intolerance. This would include carvedilol (immediate or extended release), metoprolol succinate, or bisoprolol.
• Aldosterone antagonists (Class I, evidence A) in all patients with Class II–IV HF without contraindications or intolerance when close monitoring can be ensured.

Residual Risk for HFrEF Despite Conventional GDMT
In PARADIGM-HF, study patients were followed over a median of 27 months.2,*
*Adult patients with NYHA class II–IV symptoms and an ejection fraction of 40% or less were required to take a stable dose of a beta blocker and an ACE inhibitor (or ARB) equivalent to at least 10 mg of enalapril daily, with most also receiving MRA.
McMurray J, et al. N Engl J Med. 2014;371:993-1004.
Of all patients randomized to enalapril, the absolute risk of CV death as a first event was 10.9% (n=459/4212)1

Treatment of HFrEF Stage C and D
†Hydral-Nitrates green box: The combination of ISDN/HYD with ARNI has not been robustly tested. BP response should be carefully monitored. ‡See 2013 HF guideline. §Participation in investigational studies is also appropriate for stage C, NYHA class II and III HF.

Practical Points on Use of Sacubitril/Valsartan
• Starting dose is 24/26 mg twice daily, unless patient is tolerating full dose ACEI or ARB in which case start 49/51 mg twice daily
• Target dose is 97/103 mg twice daily• After 2-4 weeks uptitrate to next dose, aim for target dose• In-hospital initiation is safe, well tolerated, and markedly
improves early outcomes• Monitor SBP, renal function and K as you would with ACEI
or ARB use• Space out dosing from other vasoactive medications if
needed• Adjust diuretics doses based on volume status
-
Cost-Effectiveness and Value of Sacubitril/Valsartan Replacing ACEI or ARB in HFrEF1
1. Gaziano TA et al. JAMA Cardiol. 2016;16:666-672.
• For every 100 000 people receiving sacubitril/valsartan, this strategy could potentially reduce hospitalizations by 3000 and reduce deaths by nearly the same number over a 2-year period. Medical savings from reduced HF admissions would be more than $27 million.

Advances in the Treatment of HF• Increased attention to prevention
• ACEI /beta-blocker /aldosterone antagonist combination previously established as the “cornerstone” of therapy
• ARNI further reduces morbidity and mortality (start in-hospital)
• Evidence that beta-blockers’ effects are not homogeneous
• Ivabradine further reduces HF hospitalization risk
• Integration of CRT and ICD device therapy into the standard therapeutic regimen
• Recognition that “special populations” of HF patients may benefit from or require different approaches
• New strategies to improve utilization of evidence-based therapies
