The interplay between heart failure and chronic kidney disease.

Chronic kidney disease (CKD) and heart failure (HF) are two globally prevalent, independent, long-term conditions, which often coexist in an individual and display a bidirectional yet interconnected relationship. The presence of CKD often leads to the development of HF and vice versa, which propagates the worsening of each disease, reflecting an intertwined disease cycle. Both HF and CKD share common risk factors, such as increasing age, diabetes, high blood pressure, obesity and smoking. Data show that approximately half of all people with HF also have CKD, which impacts patient burden and quality of life due to a significantly greater risk of hospitalization and death, compared with those that have either CKD or HF. To maximize treatment effectiveness in individuals with both HF and CKD, healthcare professionals should recognize that these two diseases are systemic conditions, representing organ-specific manifestations of similar underlying processes. It is also essential to understand the role of renin-angiotensin system inhibitors, sodium-glucose cotransporter 2 inhibitors, the nonsteroidal mineralocorticoid receptor antagonist finerenone, and glucagon-like peptide-1 receptor agonists in managing these conditions. Lifestyle modifications should also be recommended. This review discusses factors contributing to the interplay between HF and CKD and the key role of healthcare professionals in providing appropriate treatment for the co-existing diseases.
