A 65-year-old male presents with chest pain and diaphoresis. His blood pressure is 150/90 mmHg, heart rate is 50 beats/min, and he appears pale and sweaty. His ECG shows ST-segment elevation in the anterior leads. What could be the potential diagnosis, and what are the next steps?
This patient's presentation of chest pain, sweating, bradycardia, and ST-segment elevation on ECG is suggestive of an anterior wall ST-elevation myocardial infarction (STEMI), potentially with a concurrent third-degree heart block. Immediate management should include aspirin, nitrates, and arrangements for urgent reperfusion therapy, preferably primary percutaneous coronary intervention (PCI). Bradycardia may be managed with atropine or temporary pacing.
