WIlson, aged 42, presents with a medical history of hypertension, diabetes, dyslipidaemia, smoking, and family history of premature CAD presents with retrosternal crushing chest pain (10/10 in intensity), radiating down the left arm and left side of the neck. He feels nauseated and light-headed and is short of breath. Examination reveals a hypotensive, diaphoretic man in considerable discomfort with diffuse bilateral rales on chest auscultation. ECG reveals convex ST-segment elevation in leads V1 to V6.

Pregunta 7
Pregunta
A 69-year-old man develops worsening substernal chest pressure after going for a walk in the morning before work. He tells his wife he feels a squeezing pain that is radiating to his jaw and left shoulder. He appears anxious and his wife calls for an ambulance, as he is distressed and sweating profusely. Past medical history is significant for HTN and he has been told by his doctor that he has borderline diabetes. On examination in the emergency department he is very anxious and diaphoretic. His heart rate is 112 bpm and BP is 159/93 mmHg. The ECG is significant for ST depression in the anterior leads. Three doses of sublingual glyceryl trinitrate provide little relief.
