The Role of Sacubitril/Valsartan in Post-acute Myocardial Infarction

Overview

Sacubitril/Valsartan (SAC/VAL) is a new treatment of congestive heart failure (CHF) recently indicated as class I, level of evidence B in the recent European Society of Cardiology (ESC) guidelines 2016 of CHF. PARADIGM-HF trial demonstrated a significant improvement of morbidity and mortality with SAC/VAL in comparison to enalapril. So far, no data available about the effect of usage of SAC/VAL post-acute myocardial infarction (AMI) except in animal experimental models. The purpose of the research is evaluation of the effects of SAC/VAL in post-AMI in comparison to the traditional Angiotensin Converting Enzyme inhibitors (ACEs inhibitors) or Angiotensin II Receptor Blockers (ARBs) in a real-life clinical trial in treatment of post-AMI patients with reduced left ventricular (LV) systolic function.

Background and study rationale: Sacubitril/Valsartan (SAC/VAL) is now approved by the U.S. Food and Drug Administration (FDA) for heart failure with reduced ejection fraction (HFrEF) and also, recently indicated as class I indication, level of evidence B in the European Society of Cardiology (ESC) guidelines 2016 on congestive heart failure (CHF).(1) PARADIGM-HF trial demonstrated that morbidity and mortality can be improved with SAC/VAL In comparison to enalapril, it reduced the occurrence of cardiovascular death or hospitalization for CHF by 20% with a 16% reduction in all-cause mortality.(2) So far, no available data about the effect of usage of SAC/VAL in post-AMI except in animal experimental models that proved efficacy of SAC/VAL in preventing AMI-induced LV dysfunction compared with SAC/VAL, also significantly attenuated LV scar size following AMI compared with placebo .(3) Aim of the work: * This study aims to investigate the effects of SAC/VAL in post-AMI through using it instead of conventional Angiotensin Converting enzyme inhibitors (ACEs inhibitors) or Angiotensin II Receptor Blockers (ARBs) in treatment of post-AMI patients with reduced left ventricular (LV) systolic function. * Design: Randomized open label interventional clinical trial.
