Cardiovascular-Kidney-Metabolic syndrome, introduced by the American Heart Association in 2023, represents a complex and interconnected spectrum of diseases driven shared pathophysiological mechanisms. However, this framework notably excludes liver-an organ fundamental to metabolic regulation. Building on concept, Cardiovascular-Renal-Hepatic-Metabolic (CRHM) syndrome incorporates liver's pivotal role disease spectrum, particularly through its involvement via dysfunction-associated steatotic liver (MASLD). Despite increasing prevalence CRHM unified management strategies remain insufficiently explored. This review addresses following critical question: How can novel anti-diabetic agents, including sodium-glucose cotransporter-2 inhibitors (SGLT2is), glucagon-like peptide-1 receptor agonists (GLP-1RAs), dual gastric inhibitory polypeptide (GIP)/GLP-1RA, offer an integrated approach managing beyond boundaries traditional specialties? By synthesizing evidence from landmark clinical trials, we highlight paradigm-shifting potential these therapies. SGLT2is, such as dapagliflozin empagliflozin, have emerged cornerstone guideline-directed treatments for heart failure (HF) chronic kidney (CKD), providing benefits that extend glycemic control are independent diabetes status. GLP-1RAs, e.g., semaglutide, transformed obesity enabling weight reductions exceeding 15% improving outcomes atherosclerotic cardiovascular (ASCVD), diabetic CKD, HF, MASLD. Additionally, tirzepatide, GIP/GLP-1RA, enables unprecedented loss (>20%), reduces risk over 90%, improves HF with preserved ejection fraction (HFpEF), MASLD, obstructive sleep apnea. moving organ-specific approach, propose integrates agents into holistic syndrome. paradigm shift moves away fragmented, organ-centric toward more fostering collaboration across specialties marking progress precision cardiometabolic medicine.

Cardiometabolic diseases represent an escalating global health crisis, slowing or even reversing earlier declines in cardiovascular disease (CVD) mortality. Traditionally, conditions such as obesity, type 2 diabetes mellitus (T2DM), atherosclerotic CVD, heart failure (HF), chronic kidney (CKD), and metabolic dysfunction-associated steatotic liver (MASLD) were managed isolation. However, emerging evidence reveals that these disorders share overlapping pathophysiological mechanisms treatment strategies. In 2023, the American Heart Association proposed Cardiovascular-Kidney-Metabolic (CKM) syndrome, recognizing interconnected roles of heart, kidneys, system. Yet, this model omits liver—a critical organ impacted by dysfunction. MASLD, which can progress to steatohepatitis (MASH), is closely tied insulin resistance contributing directly renal impairment. Notably, MASLD bidirectionally associated with development progression CKM syndrome. As a result, we introduce expanded framework—the Cardiovascular-Renal-Hepatic-Metabolic (CRHM) syndrome—to more comprehensively capture broader inter-organ dynamics. We provide guidance for integrated diagnostic approach aimed at halting advanced stages preventing further damage. addition, highlight advances medical management target shared pathways, offering benefits across multiple systems. Viewing whole, rather than discrete entities, incorporating into framework fosters holistic strategy offers promising path addressing cardiometabolic pandemic.

Obesity has emerged as a global epidemic, creating an increased burden of weight-related diseases and straining healthcare systems worldwide. While the fundamental principle energy balance-caloric intake versus expenditure-remains central to weight regulation, real-world outcomes often deviate from simplistic predictions due multitude physiological environmental factors. Genetic predispositions, variations in basal metabolic rates, adaptive thermogenesis, physical activity, nutrient losses via fecal urinary excretion contribute interindividual differences homeostasis. Additionally, factors such meal timing, macronutrient composition, gut microbiota dynamics, diet-induced thermogenesis (DIT) further modulate utilization efficiency. This Perspective explores key determinants balance, while also highlighting clinical significance thrifty spendthrifty phenotypes. Key strategies for individualized management include precision calorimetry, circadian-aligned use protein- whole food diets enhance DIT, increases non-exercise well mild cold exposure thermogenic agents (e.g., capsaicin-like compounds) stimulate brown adipose tissue activity. A comprehensive, personalized approach obesity that moves beyond restrictive caloric models is essential achieving sustainable control improving long-term health. Integrating these multifactorial insights into practice will treatment strategies, fostering more effective enduring interventions.
