It has growing epidemiological relevance as global populations age. At its pathophysiological core lies a state of chronic systemic inflammation, coronary microvascular dysfunction and myocardial remodelling, a cascade where epicardial adipose tissue plays a pivotal amplifying role. This complexity is driving a fundamental shift in HFpEF management towards integrated cardiometabolic targeting. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) and the dual GLP1/glucose-dependent insulinotropic polypeptide (GIP)-RA tirzepatide have emerged as compelling multi-system agents, simultaneously addressing several key pathophysiological drivers of the syndrome with consistent improvements in symptoms, functional capacity and clinical outcomes. Nevertheless, questions remain regarding the long-term impact on cardiovascular outcomes, consequences of discontinuing treatment and the potential loss of muscle mass. This review examines the pathophysiological basis of HFpEF within the cardio-renal-metabolic continuum, appraising the clinical evidence, benefits and limitations of GLP-1RAs in HFpEF and discussing future directions including phenotype-directed therapy, mechanism-based combination strategies and next-generation molecules.</p>","PeriodicalId":33741,"journal":{"name":"Cardiac Failure Review","volume":"12 ","pages":"e33"},"PeriodicalIF":12.2,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13655748/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149168830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SZC is an inorganic crystalline compound that binds potassium in exchange for sodium and hydrogen throughout the gastrointestinal tract, resulting in rapid potassium lowering, whereas patiromer is a non-absorbed organic polymer that exchanges potassium for calcium in the colon and has a slower onset of action. Both agents have demonstrated efficacy in maintaining normokalaemia and enabling the continuation of renin-angiotensin-aldosterone system inhibitor therapy in heart failure. Differences in electrolyte effects and tolerability have clinical implications: patiromer is associated with hypomagnesaemia, while SZC delivers a sodium load that may predispose patients to fluid retention.

This narrative review summarises biological mechanisms and clinical applications. Across acute and chronic settings, CA125 tracks systemic and right-sided congestion, complements natriuretic peptides and shows lower dependence on renal function. Higher levels identify patients at risk for death and readmission; in ambulatory HF with reduced ejection fraction it predicts events, while in HF with preserved ejection fraction its signal is strongest in congestion-dominant phenotypes. Serial testing mirrors decongestion and clinical course; CA125-guided care has reduced rehospitalisations and improved renal function measures in selected populations. Advantages, wide availability, standardisation and low cost, support use in practice. Key gaps include phenotype-specific threshold, sampling interval and integration into actionable algorithms. Overall, CA125 has moved from tumour marker to practical tool that refines congestion assessment, improves risk stratification and informs individualised therapy in contemporary HF care.</p>","PeriodicalId":33741,"journal":{"name":"Cardiac Failure Review","volume":"12 ","pages":"e31"},"PeriodicalIF":12.2,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13655751/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The authors also summarise the underlying cellular and molecular mechanisms between HFrEF and HFpEF, with respect to cardiac remodelling, fibrosis, mitochondrial adaptations and metabolism, inflammation and inter-organ crosstalk, and provide evidence that exercise training elicits protective adaptations in HFrEF and HFpEF through some different signalling pathways targeted by exercise.
