Abstract Body: Background: Cardiovascular disease remains the most common cause of death among kidney transplant recipients, with hypertension being one of the most prevalent risk factors. Understanding the current prevalence of hypertension in this population is critical to help shape post-transplant care policies and guidelines and ensure proper management of CVD risk.

Methods: We included all kidney transplant recipients who received their transplant between 2019 and 2023 at our center and who completed 24-hour ABPM at 12 months post-transplant. We reported data in mean (SD) unless noted otherwise. BP was categorized per AHA guidelines. This study was deemed exempt by the IRB.

Results: A total of 940 patients were included in this study. Detailed results are seen in Figure 1 and Table 1. Notable to mention that 60% of the patients had blood pressure > 130/80 mmHg at 12 months post kidney transplant, with the majority being stage 1. Patients with more severe hypertension tended to be older, had lower eGFR, and had more comorbidities. They also had lower diastolic blood pressure than stage 1 HTN patients, consistent with older age. Night-time BP was significantly higher among stage 2 HTN patients.

Conclusion: Hypertension remains a prevalent condition post-kidney transplant despite the majority of patients having satisfactory kidney allograft function. Ongoing BP monitoring and assessment of out-of-office BP post-kidney transplantation is critical to ensure control of this important cardiovascular risk factor. 24-hour ABPM has several advantages in this group, including accurate measurement of out-of-office BP and detection of nocturnal hypertension, an independent risk factor for cardiovascular events. Additional studies are needed to describe the hypertension subphenotypes (e.g., sustained vs. masked) and to identify predictors of severe uncontrolled hypertension in this patient population.
