Cardiovascular Risk in HIV
Recent studies have brought into light discrepancies in cardiovascular risk assessment for individuals with HIV. Research from Massachusetts General Hospital indicates that existing risk models often miscalculate cardiovascular events, particularly among women and African descent individuals in high-income countries, while overestimating risks in low and middle-income countries. These findings are crucial for enhancing cardiovascular disease prevention strategies in the HIV population.
Study Overview
The study published in Lancet HIV on January 17, 2025, analysed data from the REPRIEVE trial. It focused on individuals with HIV aged 40-75 years, assessing their cardiovascular risk across various income levels globally.
Key Findings
- Risk Underestimation – In high-income countries, cardiovascular risk was underestimated for women and black participants
- Risk Overestimation – In low and middle-income countries, the risk was overestimated for all individuals with HIV.
- Calibration Adjustments – The PCE risk score was adjusted to improve accuracy, multiplying scores for specific demographics.
Research Methodology
The study involved 3,893 participants from 12 countries. Researchers evaluated the performance of pooled cohort equations (PCE) and the data-collection on adverse effects of anti-HIV drugs (D:A:D) risk scores.
Global Context
The REPRIEVE trial is the first large-scale study aimed at preventing HIV-related heart disease. It puts stress on the heightened cardiovascular risks faced by people living with HIV, particularly among women and black individuals.
HIV and Cardiovascular Disease
Cardiovascular diseases are a leading cause of mortality globally. Individuals with HIV often face increased risks due to various factors, including inflammation and lifestyle.
Implications for Future Research
The study calls for further research to develop more accurate cardiovascular risk scores for individuals with HIV, particularly in low and middle-income countries.
Current Treatment Landscape
Effective antiretroviral therapy (ART) exists for managing HIV. Maintaining an undetectable viral load reduces health risks, including cardiovascular diseases.
Last Subheading
Ongoing efforts to refine cardiovascular risk assessment tools are essential for improving health outcomes in the HIV population. Enhanced understanding of risk factors will guide better prevention and treatment strategies globally.
