A systematic search of peer-reviewed and grey literature published between 2013 and 2025 was conducted. Studies were included if they focused on mHealth interventions for cardiovascular event care in Africa. Data were extracted and synthesised, categorising studies by geographical distribution, intervention type and target cardiovascular condition.

Results. A total of 26 studies were identified, comprising small-scale pilots, randomised controlled trials and process evaluations. Geographically, most studies were conducted in Eastern and Western Africa. The majority focused on stroke care (20/26) rather than myocardial infarction (5/26) and predominantly addressed post-event care. The most common technologies used were smartphone applications (11/26) and SMS/phone call interventions (7/26), with one study incorporating artificial intelligence for arrhythmia screening. While positive outcomes were frequently reported, significant challenges included health system constraints, low digital literacy and financial barriers.

Conclusion. mHealth technologies demonstrate potential in improving cardiovascular event care in Africa, particularly for stroke care. However, their widespread adoption is hindered by systemic and contextual challenges. Addressing these barriers through targeted health system strengthening, digital literacy initiatives and the design of mHealth interventions that are cost-effective, user-friendly and aligned with existing workflows is essential to leveraging mHealth in cardiovascular care.
