Pre-Quiz for STEMI Pharmcotherapy

L.T., a 68-year-old male, presents to the emergency department with a 4-hour history of chest pain. His ECG reveals ST-segment elevation in the inferior leads. Upon further history, you discover that he had an ischemic stroke 2 months ago. A CT scan of the head at that time did not show any hemorrhage.

Question: Given L.T.’s history of a recent ischemic stroke, is he a candidate for fibrinolytic therapy?

J.M. is a 64-year-old woman who presents to the emergency department with a 3-hour history of chest pain radiating to her left arm. She has a history of type 2 diabetes, hypertension, and hyperlipidemia. She is currently on metformin, lisinopril, and atorvastatin. On examination, her blood pressure is 140/90 mmHg, heart rate is 88 bpm, and her ECG reveals ST-segment elevation in the anterior leads.

Question: Which of the following is the most likely underlying pathophysiology causing J.M.’s presentation?

A.C. is a 58-year-old male who comes to the clinic for a routine check-up. He has a family history of heart disease, smokes half a pack of cigarettes daily for the past 30 years, and leads a sedentary lifestyle. He occasionally experiences chest discomfort after heavy meals, which he attributes to indigestion. His blood pressure is 155/95 mmHg, and his cholesterol panel reveals an LDL of 170 mg/dL.

Question: Which of the following is the most significant modifiable risk factor for developing acute coronary syndrome (ACS) in A.C.?

MJ is a 52-year-old female presenting to the emergency department (ED) with radiating chest pain that began 3 hours ago. A 12-lead ECG shows ST elevation and hyperacute T waves in V2-4, indicating acute coronary syndrome (ACS). She has a history of hypertension, no allergies, takes amlodipine 10 mg daily, and weighs 90 kg. Her vital signs are: heart rate 114 beats/min, blood pressure 110/58 mm Hg (MAP 75 mm Hg), respiratory rate 22 breaths/min, and oxygen saturation 98%. Laboratory findings include: BG 152 mg/dL, Na 148 mmol/L, K 3.9 mmol/L, serum creatinine 1.3 mg/dL, Cl 101 mmol/L, bicarbonate 21 mmol/L, pH 7.35, Mg 1.5 mg/dL, and high sensitivity troponin T 115.8 ng/L. She received aspirin 325 mg, clopidogrel 600 mg, and sublingual nitroglycerin 0.4 mg for chest pain relief. What is the most appropriate anticoagulation treatment strategy for this patient with ACS?

S.R. is a 55-year-old male presenting with intermittent chest pain for the past two days. The pain is described as a pressure sensation, lasting for about 10 minutes each episode, and is relieved by rest. He has a history of hypertension controlled with lisinopril and has a family history of coronary artery disease. On examination, his vitals are stable. An ECG is obtained which does not show any ST-segment elevation but has T-wave inversions in the inferior leads. His initial troponin level is elevated.

Question: Based on the ECG findings and the troponin level, how would you classify S.R.’s acute coronary syndrome (ACS)?
