Cardiovascular-kidney-metabolic syndrome (CKM) represents a critical paradigm in modern medicine, encompassing the interconnected progression of cardiovascular disease, chronic kidney disease, and metabolic disorders such as diabetes and obesity. As the global burden of chronic diseases intensifies, CKM syndrome has emerged as a unifying framework that underscores the systemic nature of this condition. This book offers a comprehensive overview of CKM syndrome, exploring its pathophysiological mechanisms, demographic trends, and clinical implications. It highlights the importance of recognizing subclinical inflammation, neurohormonal and endothelial dysfunction, and insulin resistance as shared drivers of disease. Emphasizing a shift from organ-specific to integrative care, the book advocates for multidisciplinary strategies including lifestyle interventions, pharmacologic treatments, and patient-centered care. Aimed at clinicians and healthcare professionals, it serves as a practical guide for early detection, personalized management, and improving long-term outcomes in patients with CKM syndrome.
