Sacubitril-valsartan in Patients With Heart Failure With Reduced Ejection Fraction From Rural Tanzania
Sponsor: Martin Rohacek
Summary
Angiotensin-neprilysin inhibitors (ARNI) are beneficial in patients with heart failure with reduced ejection fraction. No study evaluating ARNI has been conducted in sub-Saharan Africa (except South Africa) yet, where heart failure is a major health problem. Before implementing ARNI in Tanzania, a study evaluating the benefit and safety of ARNI in Africans is needed. The aim of this interventional pre-post study is to evaluate the health status of symptomatic patients with heart failure with reduced ejection fraction who are under a chronic heart failure therapy, before and after switching angiotensin converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARB) to ARNI. Participants will be recruited at the Heart and Lung Clinic of the St Francis Regional Referral Hospital in Ifakara in rural Tanzania during a study period of 30 months, including 10 months of follow-up. A total of 238 participants will be included. The investigators hypothesize that health status, expressed by the Kansas City Cardiomyopathy Questionnaire summary score and 6-minute walking test, will improve after switching from ACE-inhibitors or ARB to ARNI. In Tanzania, sacubitril/valsartan is registered under the name Uperio®.

Interventions
Sacubitril / Valsartan Oral Tablet
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
