Key Takeaway
Recognize T2DM, ASCVD, HFpEF, MASLD, hypertension, and CKD as a single pathophysiological continuum.

This guideline presents a narrative review focused on the unified cardiometabolic disease (UCD) continuum. The authors argue that T2DM, ASCVD, HFpEF, MASLD, hypertension, and CKD are not isolated conditions but are manifestations of a single underlying pathophysiological process. This framework is intended to inform risk stratification and biomarker development.

The review identifies several key mechanistic drivers of this continuum, including visceral adipose tissue dysfunction, ectopic lipid accumulation, ceramide-mediated lipotoxicity, and NF-kB/NLRP3-driven inflammation. Other contributing factors include gut microbiome-derived endotoxemia and TMAO, adipokine dysregulation, endothelial dysfunction, and a cardiorenal amplification loop.

Pharmacologic modulation of this continuum is addressed through the use of GLP-1 receptor agonists, SGLT2 inhibitors, and finerenone across the various conditions included in the framework. Because this is a narrative review based on existing literature rather than primary clinical trials, the findings represent a conceptual synthesis of mechanisms rather than new experimental data. The scope of the evidence is limited to the established pathophysiological links described in the reviewed literature.

How this fits prior evidence

This guideline addresses a gap by proposing a unified cardiometabolic disease (UCD) framework for conditions like T2DM and CKD. It expands on existing knowledge regarding metabolic drivers, such as NF-kB and NLRP3 inflammasome pathways which were previously linked to endocrine disorders and periodontitis. While the review does not provide new trial data, it provides a conceptual framework for managing the shared mechanisms underlying these comorbid conditions.

A narrative review suggests that several common conditions, including Type 2 Diabetes, heart failure with preserved ejection fraction, and chronic kidney disease, are actually parts of one shared process. This concept is called the unified cardiometabolic disease continuum. Instead of treating these as isolated issues, this framework views them as different stages of a single underlying problem involving metabolism and organ health.

The review identifies several factors that drive this linked condition. These include problems with fat tissue, inflammation, and changes in the gut microbiome. These factors can lead to damage in both the heart and the kidneys over time. The study highlights how these shared mechanisms contribute to conditions like high blood pressure and liver disease as well.

Specific medications, such as GLP-1 receptor agonists, SGLT2 inhibitors, and finerenone, are noted for their role in managing this continuum. Because these conditions are linked, doctors may use these treatments to address multiple issues at once. This review is a summary of existing literature rather than a new clinical trial, so it provides a framework for understanding how these diseases interact.

What this means for you:
Several common heart and kidney conditions may share a single underlying cause, allowing for broader treatment goals.

Common questions

What conditions are linked in this new framework?

The review links Type 2 Diabetes, Atherosclerotic Cardiovascular Disease, Heart Failure with Preserved Ejection Fraction, Metabolic Dysfunction-Associated Steatotic Liver Disease, Hypertension, and Chronic Kidney Disease. These are viewed as part of a single cardiometabolic continuum rather than separate diseases.

What medications are mentioned for these conditions?

The review mentions GLP-1 receptor agonists, SGLT2 inhibitors, and finerenone. These medications are noted because they can address the shared biological processes found across the continuum of heart, kidney, and metabolic diseases.

What causes these conditions to be linked?

Several factors drive this link, including visceral adipose tissue dysfunction, inflammation, and gut microbiome-derived issues. These factors contribute to a cycle of damage that affects both the heart and kidneys simultaneously.

BackgroundType 2 diabetes mellitus (T2DM), atherosclerotic cardiovascular disease (ASCVD), heart failure with preserved ejection fraction (HFpEF), metabolic dysfunction-associated steatotic liver disease (MASLD), hypertension, and chronic kidney disease (CKD) share risk factors and may represent endpoints of a pathophysiological cardiometabolic continuum. We analyzed data suggesting these phenotypes arise along a unified cardiometabolic disease (UCD) continuum with distinct stages, biomarkers, and therapeutic targets.MethodsA structured narrative review was conducted using PubMed/MEDLINE, Scopus, Web of Science, and Google Scholar. Searches combined terms for mechanistic drivers (visceral adipose tissue, ceramides, lipotoxicity, NF-κB/NLRP3 signaling, gut microbiota, TMAO, adipokines, endothelial dysfunction, epicardial fat, metabolic flexibility) and clinical endpoints. Priority was given to peer-reviewed translational studies, major outcome trials, and consensus statements published between 2017-2026.ResultsCurrent evidence supports a mechanistic framework in which visceral adipose tissue dysfunction and ectopic lipid accumulation, progressing through ceramide-mediated lipotoxicity, NF-κB/NLRP3-driven inflammation, gut microbiome-derived endotoxemia and TMAO, adipokine dysregulation, endothelial dysfunction, epicardial fat-mediated cardiac remodeling, impaired metabolic flexibility, and a cardiorenal amplification loop. Stage-specific mediators (e.g., ceramides, NLRP3, TMAO, leptin-adiponectin ratio) serve as biomarkers. The benefits of GLP-1 receptor agonists, SGLT2 inhibitors, and finerenone across T2DM, ASCVD, HFpEF, MASLD, and CKD reflect pharmacologic modulation of this continuum.DiscussionData support a UCD model where T2DM, ASCVD, MASLD, HFpEF, hypertension, and CKD are manifestations of a progressive pathophysiological continuum. Framing these conditions as stages of a continuum informs risk stratification, biomarker development, and mechanism-guided therapy, providing a framework for designing trials targeting the continuum rather than individual endpoints.
