The review analyzed longitudinal intervention studies conducted in Sub-Saharan Africa, focusing on adult participants who had suffered a prior stroke. It encompassed publications and peer-reviewed papers sourced from reputable databases, including PubMed, Ovid, Cochrane, and Web of Science. Three randomized clinical trial (RCT) studies were included with sample sizes ranging from 16 to 400 participants, mean age ranged between 50 and 66 years, with 64.5% male participants. All studies applied multidisciplinary team interventions of enhanced patient follow-up involving care givers, nurse educators, physicians, and social workers. Interventions ranged from comprehensive patient education, tracking of medication adherence and enforcing healthy lifestyle behaviors (regular exercise, regular BP checks, and dietary changes). We found a decrease in Systolic Blood Pressure over time in 2 of 3 treatment groups, an improvement in medical adherence in all treatment groups, and a decrease in cholesterol levels in 1 treatment group. Evidence-based interventions involving multidisciplinary teams and comprehensive patient education were found to demonstrate promising results in reducing secondary stroke risk in Africa, leading to significant improvements in medical adherence and reductions in systolic blood pressure in the majority of treatment groups. However, more research is required to confirm the influence of these interventions on cholesterol levels and to establish their lasting advantages in preventing strokes among African communities.Keywords: secondary stroke risk, risk interventions, Sub-Saharan Africa
