Heart failure in Nigeria: protocol for a systematic review and meta-analysis

Background: Heart failure is now a significant contributor to the burden of non-communicable diseases in developing countries like Nigeria which is experiencing epidemiologic and demographic transition. The epidemiology of heart failure in this country is poorly characterized. The aim of the review is to determine the prevalence of heart failure, the associated risk factors, the aetiology, management, and outcomes of the condition in the country. Methods: Relevant databases such as PubMed /Medline, EMBASE, Web of Science, Google Scholar, African Index Medicus, and African journal online would be searched for articles published in English from January 2000 to December 2021. The analysis will include observational studies conducted among Nigerian adults aged 12 years and above. Article selection shall be conducted by pairs of independent reviewers. Data extraction shall be done by 2 independent reviewers. Results: The primary outcome would be the pooled prevalence of heart failure while the secondary outcomes would be to identify the risk factors and management of heart failure in Nigeria. Conclusion: This will be the first systematic review and meta-analysis of heart failure epidemiology in Nigeria which will hopefully identify gaps for future research and guidance for policy interventions.
