Following a heart transplant, which factor significantly contributes to a patient's risk for chronic allograft vasculopathy (CAV)?

The correct answer highlights the significant role that the race of the recipient plays in the risk of developing chronic allograft vasculopathy (CAV) after a heart transplant. Research indicates that CAV is more prevalent in specific racial and ethnic groups. For instance, studies have shown that African American recipients tend to have a higher incidence of CAV compared to their Caucasian counterparts. This increased risk may be attributed to a variety of factors, such as differences in immunologic responses, genetic predispositions, or other social determinants of health that can impact long-term outcomes in transplant recipients.

Understanding the influence of recipient race on CAV is crucial for clinicians as it can guide the selection of immunosuppressive therapies and monitoring strategies post-transplant. Recognizing the variable risks associated with different populations can help tailor individualized care plans to mitigate the risk of CAV and improve overall transplant outcomes.
