Chest Pain in a Rural Health Center
A 58-year-old man presents to a rural health center in Albania at 02:00 with severe retrosternal chest pain that began 45 minutes ago while resting. He is diaphoretic, nauseated, and anxious. His blood pressure is 150/95 mmHg, heart rate 100 bpm, respiratory rate 22/min, oxygen saturation 94% on room air, and temperature 36.8°C. He has a history of hypertension and smokes 20 cigarettes daily. The health center has no cath lab, but has a 12-lead ECG, aspirin, nitroglycerin, morphine, and oxygen. The nearest PCI-capable hospital is 2 hours away by ambulance. The on-call physician is a family medicine specialist.
1. What is the most likely diagnosis, and what immediate actions should be taken?
Read the worked answer
The most likely diagnosis is acute ST-elevation myocardial infarction (STEMI), given the typical ischemic chest pain, risk factors, and autonomic symptoms. Immediate actions: obtain a 12-lead ECG within 10 minutes of arrival; if ST elevation is present, activate the reperfusion strategy. Because PCI is >120 minutes away, administer fibrinolytic therapy (if no contraindications) within 30 minutes of ECG. Also give aspirin 150-300 mg chewed, nitroglycerin sublingual if systolic BP >100 mmHg, oxygen if saturation <90%, and morphine for pain. Arrange urgent transfer to a PCI-capable hospital for rescue or routine PCI. Monitor vital signs and rhythm continuously.
2. What are the contraindications to fibrinolytic therapy, and how would you assess them in this patient?
Read the worked answer
Absolute contraindications include prior intracranial hemorrhage, known cerebral vascular lesion, malignant intracranial neoplasm, ischemic stroke within 3 months, suspected aortic dissection, active bleeding or bleeding diathesis, significant closed-head or facial trauma within 3 months. Relative contraindications include uncontrolled hypertension (>180/110 mmHg), history of chronic severe hypertension, ischemic stroke >3 months ago, recent major surgery, pregnancy, current use of anticoagulants, and active peptic ulcer. In this patient, check blood pressure (150/95 is acceptable), ask about prior stroke, bleeding disorders, recent surgery, and use of anticoagulants. If no contraindications, proceed with fibrinolysis.
