Overview

A groundbreaking study conducted by a team of researchers from the United States has unveiled a startling reality: current cardiovascular risk models significantly underestimate the chances of heart-related events for individuals living with HIV, particularly among women and Black men in high-income countries. This pivotal research, published in the esteemed journal *Lancet HIV*, highlights an urgent need for revised predictive systems that address these alarming discrepancies.

Cardiovascular Disease and HIV

Cardiovascular disease (CVD) currently reigns as the top cause of illness and death worldwide, posing an even graver threat to people living with HIV (PWH). Past research has raised doubts about the effectiveness of existing prediction models when applied to this vulnerable population, especially with a noticeable lack of data regarding their relevance in lower and middle-income countries (LMICs).

Study Details

The multifaceted study led by investigators from Massachusetts General Hospital, a cornerstone of the Mass General Brigham healthcare system, engaged an international network of experts. They aimed to assess the accuracy of established atherosclerotic cardiovascular disease (ASCVD) risk estimates in predicting cardiovascular events among global populations infected with HIV.

Key Findings

By analyzing data from the Randomized Trial to Prevent Vascular Events in HIV (REPRIEVE), the study encompassed a diverse group of individuals with HIV from various economic backgrounds across multiple continents. The findings were revealing: while cardiovascular events were severely underestimated for women and Black men in high-income nations, the models tended to overestimate the risk for all PWH in LMICs.

Expert Opinions

Patrice Desvigne-Nickens, a medical officer at the National Heart, Lung, and Blood Institute (NHLBI), emphasized the significance of these findings. "This research enables scientists to refine cardiovascular disease prediction models tailored specifically for people living with HIV," he stated. He further noted the importance of conducting these assessments within distinct population subgroups to ensure accurate risk calculations.

Steven Grinspoon, chief of the Massachusetts General Hospital Metabolism Unit, underscored the vital need for CVD prediction models that consider the nuances of different regions and demographics. "These findings call for models that truly reflect the cardiovascular risk landscape for people living with HIV, especially those in low and middle-income countries," he pointed out.

Conclusion

As the global community continues to grapple with the complicated interplay between HIV and cardiovascular health, this study serves as a clarion call for more targeted research and interventions. With cardiovascular disease being an impending threat among individuals living with HIV, understanding and addressing these risks can lead to better preventive measures and potentially save lives across the globe.
