First seen Jun 27, 2026 · Last updated Jul 02, 2026 · Updated 1 time
Summary
This study looks at whether changing from standard heart failure medications to a newer drug (sacubitril-valsartan) can improve the health and daily life of people with heart failure in rural Tanzania. About 298 adults with heart failure will be switched to the new drug and followed for 10 months. The goal is to see if they feel better, can walk farther, and have fewer symptoms.
