Interestingly, alterations in myokines have been described in patients with heart failure (HF) that are associated with adverse structural and functional left ventricular remodelling and poor cardiac outcomes. Recent experimental and clinical studies have shown that the muscle regulation of a number of myokines is altered in chronic kidney disease (CKD) thus representing a new molecular aspect of the pathophysiology of skeletal myopathy present in patients with CKD. Muscle dysregulation of myokines may contribute to a number of disorders in non-dialysis and dialysis patients with CKD, including the high risk of developing HF. This possibility would translate into a range of new diagnostic and therapeutic options. In fact, the measurement of circulating myokines opens their possible usefulness as biomarkers to personalize exercise training and pharmacological therapies for the prevetion and treatment of HF in patients with CKD and skeletal myopathy. This review will analyze information on some myokines that target the heart and are altered at the level of skeletal muscle and circulation in patients with CKD.</p>","PeriodicalId":19078,"journal":{"name":"Nephrology Dialysis Transplantation","volume":null,"pages":null},"PeriodicalIF":4.8,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142109922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alleviating signs and symptoms of volume overload represents a foundational HF treatment target that is achieved using loop diuretics in the acute and chronic setting. Recent work has provided evidence to support guideline-directed medical therapies, such as sodium glucose cotransporter 2 (SGLT2) inhibitors and mineralocorticoid receptor (MR) antagonists, as important adjunct diuretics that may act synergistically when used with background loop diuretics in people with chronic HF. Furthermore, there is growing interest in understanding the role of SGLT2 inhibitors, carbonic anhydrase inhibitors, thiazide diuretics, and MR antagonists in treating volume overload in patients hospitalized for acute HF, particularly in the setting of loop diuretic resistance. Thus, the current review demonstrates that: (i) SGLT2 inhibitors and MR antagonists confer long-term cardioprotection in chronic HF patients but it is unclear whether natriuresis or diuresis represents the primary mechanisms for this benefit, (ii) SGLT2 inhibitors, carbonic anhydrase inhibitors, and thiazide diuretics increase natriuresis in the acute HF setting, but implications on long-term outcomes remain unclear and warrants further investigation, and (iii) a multi-nephron segment approach, using agents that act on distinct segments of the nephron, potentiate diuresis to alleviate signs and symptoms of volume overload in acute HF.</p>","PeriodicalId":19078,"journal":{"name":"Nephrology Dialysis Transplantation","volume":null,"pages":null},"PeriodicalIF":4.8,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11361814/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139996921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
