PATIENT PRESENTATION
A 70-year-old male presents with a recent onset of substernal chest pain. The pain is sharp and pleuritic and has started to radiate to the left trapezius muscle. Inspiration causes the pain to become more severe, but sitting up and leaning forward helps to relieve it. This patient’s review of systems reveals a recent viral illness, including “flu-like” symptoms and low-grade fever for 1 week. His past medical history is otherwise unremarkable. His current temperature is 100.9°F, BP is 130/84 mm Hg, HR is 95 bpm, RR is 24 breaths/min, and O2 Saturation is 99% in room air. Heart auscultation reveals a scratchy, rubbing sound at the lower left sternal border. Lungs are clear, but breathing is shallow. The patient is referred to the emergency room. ECG reveals widespread ST-segment elevation and chest X-ray (CXR) is normal.
