Treatment Approaches in Non-ST-Segment Elevation Acute Coronary Syndrome: From Guidelines to Clinical Practice

Non-ST-segment elevation acute coronary syndrome (NSTE-ACS) encompasses a spectrum of clinical presentations ranging from unstable angina to non-ST-segment elevation myocardial infarction (NSTEMI), representing a significant challenge in contemporary cardiology. This paper overviews treatment approaches in NSTE-ACS, synthesizing evidence from guidelines and clinical practice. After discussing the pathophysiology and clinical presentation of NSTE-ACS, we outline key recommendations from major guidelines, emphasizing medical and invasive management strategies. Pharmacological interventions, including antiplatelet and anticoagulation therapies, are explored alongside considerations for analgesia and symptom management. Invasive approaches such as coronary angiography and percutaneous coronary intervention (PCI) are discussed, highlighting timing and selection criteria for optimal outcomes. Risk stratification tools and their implications for prognosis are analyzed, focusing on special populations and challenges in risk assessment.

Furthermore, we address controversies in NSTE-ACS management, including the balance between risks and benefits of interventions, adherence to guidelines, and emerging therapies. Additional sections cover topics such as patient education, shared decision-making, and considerations for health equity and access to care. The review concludes with insights into future directions in NSTE-ACS management, emphasizing the importance of multidisciplinary collaboration, quality improvement initiatives, and a patient-centered approach. This review is a valuable resource for clinicians involved in the care of NSTE-ACS patients, providing evidence-based guidance and addressing key issues in clinical practice.
