A 68-year-old woman with longstanding insulin-dependent diabetes mellitus and hypertension presents with epigastric burning, profuse diaphoresis, dyspnea, and nausea following a fatty meal. Initial triage vitals suggest a vagal, bradycardic picture rather than classic crushing chest pain. Longstanding insulin-dependent type 2 diabetes mellitus, hypertension, hyperlipidemia, former smoker (quit 8 years ago). No prior myocardial infarction. Takes metformin, insulin glargine, lisinopril, atorvastatin, and aspirin 81mg daily.
Acute Resuscitation Milestones & Priorities
Clinical phases and key interventions encountered in this emergency module:
Triage Recognition of Atypical Presentation
Right Ventricular Infarction Recognition
Hemodynamic Optimization & Antiplatelet Loading
Definitive Reperfusion & Risk-Stratified Transfer
High-Yield Clinical Pearls
Diabetic women commonly present with atypical ACS symptoms (epigastric burning, dyspnea, diaphoresis) rather than classic crushing substernal pain — maintain a low threshold for ECG.
Inferior STEMI with hypotension mandates immediate right-sided ECG (V4R) to assess for right ventricular infarction, which is preload-dependent.
Nitrates and diuretics are contraindicated in RV infarction due to profound preload dependence; judicious crystalloid is the initial intervention.
Norepinephrine is the preferred first-line vasopressor in cardiogenic shock (alpha-mediated vasoconstriction without tachycardia); avoid high-dose dobutamine and dopamine.
P2Y12 inhibitor loading should not be delayed for hypothetical CABG scenarios in isolated inferior STEMI; the risk of acute stent thrombosis outweighs surgical conversion risk.
