The incidence of heart transplants in the USA has increased by 85.8% since 2011, resulting in a growing population of recipients requiring long-term immunosuppressive therapy. While essential for preventing organ rejection, this therapy significantly increases melanoma risk. This meta-analysis investigates the incidence and risk factors of melanoma in heart transplant recipients. A systematic review and meta-analysis were conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, including observational studies reporting melanoma incidence in heart transplant recipients. Relative risk (RR) was synthesized from standardized incidence ratios, hazard ratios, incidence rate ratios, and standardized mortality ratios. The meta-analysis incorporated 10 studies, including 22 415 heart transplant recipients. The pooled RR was 2.21 (95% confidence interval: 1.32-3.71; P = 0.003), indicating a significantly elevated melanoma risk. This study highlights the critical need for preventive dermatological strategies in heart transplant recipients and calls for further research into the impact of different immunosuppressive regimens on melanoma risk. Despite limitations, these findings offer valuable insights for optimizing long-term patient care.
