Sudden pain between the shoulder blades with a hypertrophied left ventricle—what do you suspect?

Sudden pain between the shoulder blades with a hypertrophied left ventricle—what do you suspect?

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

Answer: (B)

The key idea is recognizing the pattern of sudden, severe, tearing chest or back pain in a patient with long-standing hypertension. Hypertension frequently leads to left ventricular hypertrophy, and the same vascular stress that causes LV changes also predisposes the aorta to dissection. An intimal tear lets blood split the media, creating a false lumen that often tracks along the thoracic aorta. When the dissection involves the descending (thoracic) aorta, the pain can radiate between the shoulder blades, which is a classic clue. Pulmonary embolism usually presents with sudden pleuritic chest pain and shortness of breath, not the characteristic tearing back pain nor the clear link to LV hypertrophy. Myocardial infarction tends to give substernal pressure-like chest pain that radiates to the arm or jaw rather than a tearing back pain, and it’s not specifically tied to LV hypertrophy. Aneurysm rupture can cause sudden severe pain and shock, but the association with a long-standing hypertensive LV and the classic back-pain radiating pattern points more toward dissection, especially in the context of a hypertensive patient. So the presentation best fits an aortic dissection due to acute intimal tear in the setting of hypertension (LV hypertrophy), with back pain signaling thoracic involvement.
