A patient presents with sudden anterior chest pain and pain between the shoulder blades; prior stent placement; what is the suspected diagnosis?

• A. Aortic Dissection
• B. Myocardial Infarction
• C. Pulmonary Embolism
• D. Aneurysm Rupture

Answer: (A)

Acute aortic dissection presents with abrupt, severe chest pain that often radiates to the back, between the shoulder blades. The tearing quality and the radiation pattern reflect the dissection’s propagation along the aorta, which can extend from the ascending to the descending portions. A history of prior vascular procedures or stent placement suggests underlying aortic or vascular wall disease, increasing this risk. This presentation helps distinguish it from other acute chest pain causes: myocardial infarction can mimic chest pain but back radiation is less typical; pulmonary embolism usually brings pleuritic chest pain with dyspnea; aneurysm rupture often occurs in a known aneurysm and can present with shock. Recognize that this scenario points to acute aortic dissection. Immediate management focuses on rapid imaging (eg, CT angiography) to confirm the diagnosis and aggressive blood pressure and heart rate control (eg, IV beta-blockade) to limit shear stress, with surgical evaluation for proximal dissections.
