TY - CHAP M1 - Book, Section TI - Acute Coronary Syndromes A1 - Auguste, Uschi A1 - Kanei, Yumiko A2 - Go, Ronaldo Collo PY - 2019 T2 - Critical Care Examination and Board Review AB - An acute coronary syndrome (ACS) encompasses a clinical spectrum of myocardial ischemia ranging from unstable angina (UA) and non–ST-segment elevation myocardial infarction (NSTEMI) to ST-segment elevation myocardial infarction (STEMI), and represents an acute phase of coronary atherosclerosis.1-3 Early recognition, diagnosis, and prompt revascularization of the culprit lesion with percutaneous coronary intervention (PCI) is the contemporary management strategy for patients presenting with STEMI or high-risk NSTEMI.1,2,4,5 Acute plaque rupture and subsequent atherothrombosis with consequent myocardial injury is the most common etiology for ACS; however, myocardial necrosis in the absence of unstable plaque may ensue in critically ill patients who are admitted for non–cardiac-related conditions, such as pulmonary embolism and septic shock. These patients pose a unique diagnostic and management challenge, as concomitant multiorgan failure, electrolyte derangements, and coagulopathy further complicate the clinical picture.6-8 In this chapter, we will review the universal definition of myocardial infarction (MI) and the related patient presentations, risk stratification models, complications, and management strategies.
