Risk and management of cardiac disease in kidney and liver transplant recipients.

Organ transplantation is the treatment of choice for individuals with kidney failure requiring kidney replacement therapy, as well as for those with end-stage liver disease. Despite the significant reduction in long-term morbidity and mortality with transplantation, kidney and liver allograft recipients remain at high risk for cardiovascular disease (CVD) and premature death from cardiovascular causes. This heightened risk is represented across all phenotypes of CVD, including coronary heart disease, heart failure, arrhythmias, valvulopathies and pulmonary hypertension. Pre-existing vascular risk factors for CVD, coupled with superimposed cardiovascular-kidney-metabolic derangements after transplantation, driven at least in part by post-transplant weight gain, immunosuppressive therapies and de novo risk factors such as dyslipidaemia and diabetes, coalesce to increase total CVD risk. In this review, we summarise pathophysiological considerations for both the short- and long-term increase in CVD risk following kidney/liver transplantation. We review the different phenotypes of CVD, with unique considerations for post-transplant care in this patient population. Finally, we highlight the need for awareness about long-term CVD risk and a multidisciplinary approach to managing organ-specific CVD risk in kidney and liver transplant patients.
