The 29th International Congress of the Polish Cardiac Society was held in Krakow from 25 to 27 September 2025. During numerous sessions, the challenges associated with diagnosing and treating cardiovascular diseases in patients with chronic kidney disease were discussed. This report summarises the recommendations presented during the Congress regarding the management of cardiovascular complications in this group of patients. Particular attention was devoted to guidelines and diagnostic challenges related to the use of anticoagulant therapy in patients with chronic kidney disease and atrial fibrillation. Recommendations concerning renin–angiotensin system blockade were also presented, along with approaches to managing hyperkalaemia, hypotension, and deterioration of renal function during this treatment. The Congress also summarised guidance on lipid-lowering therapy in chronic kidney disease and addressed issues related to the management of heart failure in these patients. The problem with the diagnosis of chronic kidney disease was also highlighted, as it is associated with intensified progression of renal dysfunction and the de velopment of cardiovascular complications.
