Key result
Using a cardiovascular risk prediction chart instead of single clinical criteria decreased the proportion of adults eligible for hypertension treatment from 48.7% to 22.0%.
Why the study?
There is a need to evaluate cardiovascular risk and treatment eligibility in Angolan adults using integrated risk prediction rather than single clinical criteria.
Does the use of cardiovascular risk prediction charts compared to single clinical values change the proportion of individuals eligible for pharmacological treatment in Angolan adults?
Cross-Sectional (n=468)
Does the use of cardiovascular risk prediction charts compared to single clinical values change the proportion of individuals eligible for pharmacological treatment in Angolan adults?
Using cardiovascular risk prediction charts instead of single clinical criteria significantly reduces the proportion of individuals recommended for antihypertensive treatment, promoting better resource allocation in resource-limited settings.

Risk-based eligibility identifies fewer for treatment than hypertension criteria alone in untreated Angolans; leaves open whether this improves outcomes in similar settings.
From a community-based survey conducted in Angola, 468 individuals aged 40 to 64 years and not using drug therapy were evaluated according to the World Health Organisation STEPwise Approach to Chronic Disease Risk Factor Surveillance. Using data from tobacco use, blood pressure, blood glucose, and total cholesterol levels, we estimated the 10-year risk of a fatal or nonfatal major cardiovascular event and computed the proportion of untreated participants eligible for pharmacological treatment according to clinical values alone and total cardiovascular risk. The large majority of participants were classified as having a low (<10%) 10-year cardiovascular risk (87.6%), with only 4.5% having a high (≥ 20%) cardiovascular risk. If we consider the single criteria for hypertension, 48.7% of the population should be considered for treatment. This value decreases to 22.0% if we apply the risk prediction chart. The use of hypoglycaemic drugs does not present any differences (19.0% in both situations). The use of lipid-lowering drugs (3.8%) is only recommended by the risk prediction chart. This study reveals the need of integrated approaches for the treatment of cardiovascular disorders in this population. Risk prediction charts can be used as a way to promote a better use of limited resources.

Pedro et al. (2018) conducted a cross-sectional in Cardiovascular risk (n=468). Risk prediction chart vs. Single clinical criteria was evaluated on Eligibility for pharmacological treatment for hypertension. Using a cardiovascular risk prediction chart instead of single clinical criteria decreased the proportion of adults eligible for hypertension treatment from 48.7% to 22.0%.
