Of heart and kidney: A complicated love story

Abstract

The multiple connections that exist between the cardiovascular system and the kidney lead to a complex cardiovascular and renal medicine relationship. It is well established in the literature that chronic kidney disease (CKD) is an important and independent risk factor for cardiovascular disease (CVD). The prevalence of CKD in the general population is about 7%, comparable with the prevalence of diabetes. The main causes of CKD are diabetes and hypertension, worldwide. The prevalence of CVD in the CKD population ranges between 7 and 85% according to the CKD stage and type, and the patient diagnosed with CKD has a higher risk of dying of CVD than of starting renal replacement therapy. There are some particular aspects of CVD in CKD patients that differ from the general population, making its prevention and treatment a challenge for both cardiologists and nephrologists. © The European Society of Cardiology 2012.
