Abstract

Pre-kidney transplant cardiac screening has garnered particular attention from guideline committees as an approach to improving post-transplant success. Screening serves two major purposes: To more accurately inform transplant candidates of their risk for a cardiac event before and after the transplant, thereby informing decisions about proceeding with transplantation, and to guide pre-transplant management so that post-transplant success can be maximized. Transplant candidates on dialysis are more likely to be screened for coronary artery disease than those not being considered for transplantation. Thorough history and physical examination taking, resting electrocardiography and echocardiography, exercise stress testing, myocardial perfusion scintigraphy, dobutamine stress echocardiography, cardiac computed tomography, cardiac biomarker measurement, and cardiac magnetic resonance imaging all play contributory roles towards screening for cardiovascular disease before kidney transplantation. In this review, the importance of each of these screening procedures for both coronary artery disease and other forms of cardiac disease are discussed.

Keywords: Dobutamine stress echocardiography, Myocardial perfusion scanning, Chronic kidney disease, Coronary angiography, Magnetic resonance imaging

Core tip: Transplant candidates on dialysis are more likely to be screened for heart disease than those not being considered for transplantation. Screening in this population is driven by complex and competing priorities. Clinicians have a duty both to the candidate’s survival and to allograft success. Few cardiovascular disease conditions detected by screening require immediate attention; there is a trade-off between the risks from a given procedure that are immediate and the benefits from that procedure which are more remote. It is important to clearly distinguish coronary artery disease from other cardiac conditions to help guide the selection of appropriate diagnostic strategies.
