Acute Coronary Syndrome Study Guide
Overview of Acute Coronary Syndrome
✔️Acute Coronary Syndrome is a spectrum of clinical conditions ranging from unstable angina to myocardial infarction, all generally caused by plaque rupture, platelet aggregation, and thrombus formation.
✔️The first critical hour of assessment requires a structured triage protocol focusing on an abnormal ECG, the clinical context of the patient, and hemodynamic stability.
Pathophysiology and Classification :
✔️Unstable Angina: Caused by a non-occlusive or transiently occlusive thrombus that leads to ischemia without myocardial necrosis.
✔️NSTEMI:Characterized by a partial or intermittent occlusion that results in myocyte necrosis .
✔️STEMI:The most severe form, involving complete and persistent occlusion of a major epicardial artery, causing transmural ischemia and muscle death. Clinical Presentation ✔️Classic Symptoms: Patients typically present with substernal chest tightness or crushing pressure, often radiating to the jaw or left arm .
✔️Associated Symptoms: Common findings include diaphoresis, nausea, shortness of breath, and anxiety.
✔️Atypical Presentations: Women, elderly patients, and those with diabetes are more likely to present with atypical symptoms such as fatigue, epigastric pain, or dyspnea alone . ✔️Critical Timing: Pain at rest is considered a harbinger of imminent infarction and must be treated as a medical emergency.
Diagnostic Criteria and Matrix
✔️ECG Requirements: A 12-lead ECG should be performed and interpreted within 10 minutes of arrival .
✔️STEMI Diagnosis: Diagnosed by ST-segment elevation of 1 mm or more in two contiguous limb leads or 2 mm or more in two contiguous chest leads.
✔️NSTEMI and Unstable Angina ECGs: These may show ST-segment depression, T-wave inversion, or may appear normal..
✔️Cardiac Biomarkers: High-sensitivity cardiac troponin is the key differentiator between unstable angina and NSTEMI . Troponin remains normal in unstable angina but is elevated in both NSTEMI and STEMI .
Immediate Management and Pharmacotherapy
✔️Immediate Medications: Often remembered by the MONA-BASH mnemonic, management includes Aspirin 324 mg chewed, Nitroglycerin for ischemia, Morphine for refractory pain, and Oxygen if SpO2 is below 90%.
✔️Anti-ischemic Therapy: Additional immediate treatments include oral Beta-blockers, Anticoagulation with heparin or enoxaparin, and high-intensity Statins.
✔️STEMI Reperfusion: The primary goal for STEMI is rapid reperfusion. Primary Percutaneous Coronary Intervention is preferred with a door-to-balloon time goal of less than 90 minutes .
✔️Fibrinolysis: This is an alternative for STEMI patients if PCI cannot be performed within 120 minutes of first medical contact. Risk Stratification for NSTEMI and Unstable Angina ✔️Early Invasive Strategy: An angiogram within 24 hours is required for high-risk patients showing refractory angina, hemodynamic instability, life-threatening arrhythmias, or a GRACE score above 140.
✔️Delayed Strategy: Stable patients with intermediate risk may undergo angiography within 24 to 48 hours. Long-Term Care and Secondary Prevention
✔️Dual Antiplatelet Therapy: Patients should remain on Aspirin and a P2Y12 inhibitor such as ticagrelor or clopidogrel for 12 months post-event.
✔️Medication Optimization: Long-term management includes high-intensity statins, Beta-blockers, and ACE inhibitors to prevent left ventricular remodeling.
✔️Lifestyle Components: Success in secondary prevention requires exercise training, smoking cessation, strict blood pressure management, and psychosocial support.
