Risk assessment in the prevention of cardiovascular disease in low-resource settings

IntroductionCardiovascular disease (CVD) prevalence is increasing in low- and middle-income countries. Total risk assessment is key to prevention.MethodsStudies and guidelines published between 1990 and 2013 were sought using Medline database, PubMed, and World Health Organization report sheets. Search terms included ‘risk assessment’ and ‘cardiovascular disease prevention’. Observational studies and randomized controlled trials were reviewed.ResultsThe ideal risk prediction tool is one that is derived from the population in which it is to be applied. Without national population-based cohort studies in sub-Saharan African countries like Nigeria, there is no tool that is used consistently. Regardless of which one is adopted by national guidelines, routine consistent use is advocated by various CVD prevention guidelines.ConclusionsIn low-resource settings, the consistent use of simple tools like the WHO charts is recommended, as the benefit of a standard approach to screening outweighs the risk of missing an opportunity to prevent CVD.
