Chronic kidney disease in patients with cardiac rhythm disturbances or implantable electrical devices: clinical significance and implications for decision making-a position paper of the European Heart Rhythm Association endorsed by the Heart Rhythm Society and the Asia Pacific Heart Rhythm Society

The kidney exerts multiple functions, and pathophysiological interactions between the kidney and the heart have important clinical implications, but it has only recently become clear that these interactions should be studied across the whole spectrum of reduced kidney function and not only in cases with severe, end-stage renal disease (ESRD), as has been done for many years.1 The prevalence of chronic kidney disease (CKD), defined as a glomerular filtration rate (GFR) of 3 months, exceeds 10% in the adult population and reaches 47% in subjects older than 70 years, according to data from the USA, with a trend towards a recent increasing prevalence.1,2 Many interactions between kidney and cardiovascular functions have important implications for clinical management and health policy ( Figure 1 ), since even mild forms of kidney disease are associated with an increased risk of cardiovascular morbidity and overall mortality, and renal function may worsen over time.1,3 Figure 1 Stages of the development and progression of chronic kidney disease (CKD), including complications and strategies to improve outcomes. Modified from Eckardt et al. 1 GFR, glomerular filtration rate. Although cardiovascular disease (CVD) and cardiac disorders are more frequent and severe in CKD, they are often not recognized, or undertreated, in view of the complexity of patient management in this setting.4 On the other hand, the presence and evolution of CKD is often not evaluated and monitored in patients with various forms of heart diseases, including patients with cardiac rhythm disturbances, a setting where CKD is associated with challenging decision-making on the management of specific treatments and interventions. In patients with cardiac diseases, CKD predisposes to acute kidney injury and vice versa , and both may strongly influence clinical management of cardiac conditions. Considering the need for increasing the awareness of …
