Abstract

Background: The LIFE (LCZ696 In Hospitalized Advanced Heart FailurE) trial, which evaluated sacubitril/valsartan in patients with advanced heart failure (HF) with reduced ejection fraction and recent New York Heart Association functional class IV symptomatology, did not require tolerance to a renin angiotensin system antagonist before initiating sacubitril/valsartan, thus affording an opportunity to study the tolerability of sacubitril/valsartan in advanced HF with reduced ejection fraction. Objectives: The goal of this analysis of the LIFE trial is to characterize the tolerability of initiating sacubitril/valsartan in patients with chronic advanced HF with reduced ejection fraction. Methods: In the LIFE trial, 445 subjects with advanced HF entered an unblinded run-in period of 3-7 days with sacubitril/valsartan 24/26 mg twice a day. The authors compared characteristics of subjects completing and failing run-in, performed multivariable analysis of clinical parameters associated with run-in failure, and developed a predictive model for short-term intolerance to sacubitril/valsartan. Results: Of 445 subjects entering run-in, 73 (18%) were intolerant of sacubitril/valsartan. Reasons for intolerance included systolic blood pressure <90 mm Hg (59%), symptoms of hypotension/dizziness with systolic blood pressure >90 mm Hg (19%), and renal dysfunction (creatinine >2.0 mg/dL) (12%). Multivariable predictors of intolerance included lower mean arterial pressure, lower serum chloride, presence of an implantable cardioverter-defibrillator and/or cardiac resynchronization device, moderate or greater mitral regurgitation, nonuse of angiotensin-converting enzyme inhibitor or angiotensin receptor blocker at the screening visit, and use of insulin at screening. Subjects with 4 or more predictors had a 48.9% probability of sacubitril/valsartan intolerance. Conclusions: Intolerance to low doses of sacubitril/valsartan is common in patients with advanced chronic HF with reduced ejection fraction and may be predicted by the presence of certain risk factors.
