ContriBution of Digital RemOte MoniToring to IMPROVing The Effectiveness of Treatment in Patients With Chronic Heart Failure With Low Ejection Fraction

BOT-IMPROVE-HF is a two-center, parallel group study designed to evaluate the efficacy of up-titration of heart failure treatment using digital remote monitoring after hospitalization due to heart failure decompensation. Patient will be randomized before discharge using a simple computer generated sequence to either remote monitoring or usual care group. Patients\' condition in the \"remote monitoring\" arm will be assessed by mini-program based on a personal messenger and laboratory rests results will be asked by phone call. If these measures show safety and tolerability of the doses of the drugs, they will be increased to target or maximally tolerated doses. The follow-up period will be 6 months - 24 weeks. Patients of the usual care group will be followed by their general practitioner and/or cardiologist. All patients will be contacted after 6 months to assess outcomes.
