Sacubitril-valsartan in Patients With Heart Failure With Reduced Ejection Fraction From Rural Tanzania

A 36-hour wash-out of ACE inhibitors before initiating ARNI will be done, because of a risk of angioedema if ARNI is started without a wash-out period. The ACE inhibitor or ARB will be switched to sacubitril/valsartan 50mg twice daily (24.3 mg sacubitril, 25.7mg valsartan) for two weeks, increased to 100mg twice daily for three weeks, followed by 200mg twice daily
