Insights
Cardiovascular risk scores for people living with HIV (PLHIV) in Brazil were evaluated. The D:A:Dr score shows strong agreement with the Framingham Risk Score, suggesting it as a viable alternative for assessing cardiovascular risk in PLHIV.
Area of Science:
- Cardiology
- Infectious Diseases
- Public Health
Background:
- People living with HIV (PLHIV) face double the risk of cardiovascular diseases (CVD).
- Accurate cardiovascular risk (CVR) assessment is crucial for PLHIV, yet no validated calculator exists for this population in Brazil.
- Existing CVR tools may not fully capture the specific needs of PLHIV.
Purpose of the Study:
- To evaluate the agreement between three cardiovascular risk scores in Brazilian PLHIV.
- To determine the suitability of the Framingham Risk Score (FRS), Atherosclerotic Cardiovascular Disease (ASCVD) Risk Score, and the D:A:Dr score for assessing CVR in PLHIV.
- To identify a reliable CVR calculator for PLHIV in Brazil.
Main Methods:
- A cross-sectional study involving 265 PLHIV aged 40-74 years in Brazil.
- Comparison of CVR using weighted Kappa coefficient and Bland-Altman plots for FRS, ASCVD, and D:A:Dr scores.
- Analysis of demographic and clinical data, including age, sex, hypertension, and viral load.
Main Results:
- Almost perfect agreement was found between the D:A:Dr score and FRS (k=0.82).
- Substantial agreement was observed between FRS and ASCVD (k=0.74), and between D:A:Dr and ASCVD (k=0.70).
- Increased discordance between scores was noted at higher CVR levels, as indicated by Bland-Altman plots.
Conclusions:
- The Framingham Risk Score and the D:A:Dr score are adequate for classifying CVR in Brazilian PLHIV.
- The D:A:Dr score is a suitable alternative to the FRS for assessing cardiovascular risk in this population in Brazil.
- International guidelines support the use of D:A:Dr, reinforcing its utility for PLHIV care.
Abstract:
People living with HIV (PLHIV) have twice the risk of developing cardiovascular diseases, making it essential to identify high cardiovascular risk (CVR). However, there is no validated CVR calculator for PLHIV in Brazil. We performed a cross-sectional study with 265 individuals living with HIV, aged 40 to 74 years, to assess the agreement between three CVR scores: Framingham Risk Score (FRS), Atherosclerotic Cardiovascular Disease (ASCVD) Risk Score, and a specific for PLHIV, Reduced Data Collection on Adverse Effects of Anti-HIV Drugs (D:A:Dr). We assessed agreement using the weighted Kappa coefficient and the Bland-Altman plot. The median age was 52 years (47-58), 58.9% were men, 34% were hypertensive and 8.3% had a detectable viral load. There was an almost perfect agreement between D:A:Dr x FRS (k = 0.82; 95% CI 0.77-0.87; p < 0.001), and substantial agreement between FRS vs. ASCVD (k = 0.74; 95% CI 0.69-0.79; p < 0.001) and between D:A:Dr vs. ASCVD (k = 0.70; 95% CI 0.64-0.76; p < 0.001). The Bland-Altman plot revealed greater discordance between scores as the CVR increased. Our results suggest that the FRS and the D:A:Dr are adequate to classify the CVR in this population, and the D:A:Dr score can be used as an alternative to the FRS in Brazil, as other international guidelines have already advocated.
