Chronic postsurgical pain after cardiac surgery: A narrative review.

Chronic postsurgical pain (CPSP) is a prevalent and debilitating sequela of cardiac surgery, exerting a profound impact on patients' quality of life, functional recovery, and healthcare systems. Its pathophysiology includes complex mechanisms, including peripheral and central sensitization, neuroplastic alterations, and inflammatory pathways, influenced by demographic, psychological, and perioperative factors. Inadequate management of acute pain is a critical contributor to its development. This review examines the etiology of CPSP, presents key risk factors, and critically evaluates pharmacological and nonpharmacological interventions. Particular attention is devoted to the role of regional anesthesia techniques and emerging preventive and therapeutic strategies, highlighting the necessity of multidisciplinary, evidence-informed approaches to address this persistent clinical challenge.
