Ambulatory blood pressure monitoring in solid organ transplantation.
Solid organ transplant recipients are at an increased risk for hypertension and cardiovascular disease. To assist in their management, 24-h ambulatory blood pressure monitoring (ABPM) has become increasingly used in both clinical research settings and practice. ABPM has been used to better define post-transplant hypertension incidence and prevalence in different solid organ transplantation populations. ABPM provides additional information on cardiovascular risk beyond that obtained by clinic-based readings, based on its ability to assess 24-h blood pressure (BP) load, detect nocturnal non-dipping, and predict target organ damage. It has provided some assurance about the safety of living kidney donation. Information from ABPM can be used to guide living kidney donor selection, and because ABPM-related data has been correlated with clinically important kidney and heart transplant recipient outcomes, it may be a valuable adjunct in their management. Despite these advantages, barriers to wider use of ABPM include expense, clinical inertia in hypertension management, lack of prospective clinical trial data, and clinical problems that compete with hypertension for attention such as acute or chronic allograft dysfunction. The increasing amount of research and clinical use for ABPM may allow for closer assessment and intervention to help address the increased cardiovascular risk faced by many solid organ transplant recipients.
