Risk factors for arterial hypertension after liver transplantation

Abstract Arterial hypertension represents a common complication of immunosuppressive therapy after liver transplantation (LT). The aim of the study is to evaluate the prevalence and risk factors associated with hypertension after LT. From a cohort of 323 cirrhotic patients who underwent LT from 2008 to 2012, 270 patients were retrospectively evaluated, whereas 53 (16.4%) patients deceased. Hypertension was defined as blood pressure ≥140/90 mm Hg in at least two visits and/or the need for antihypertensive therapy. The prevalence of hypertension was 15% before LT and significantly increased up to 53% after LT ( P P  = .02), alcoholic cirrhosis before LT (OR, 3.38; 95% CI, 1.44–8.09; P  = .005), and new-onset hepatic steatosis after LT (OR, 2.13; 95% CI, 1.10–4.11; P  = .02). Tacrolimus, the etiology and severity of liver disease, and other immunosuppressive regimens were not related to the development of hypertension after LT. In our cohort, the prevalence of arterial hypertension has increased up to 53% after LT, and metabolic comorbidities and immunosuppressive treatment with mammalian target of rapamycin inhibitors are the risk factors for the development of hypertension after LT.
