Pain from the heart is often referred to which structures?

• A. Anterior neck, upper thorax, left upper extremity
• B. Posterior thigh and calf
• C. Facial region
• D. Pelvic area

Answer: (A)

Referred pain from the heart tends to show up in areas that share the same neural pathways as the heart’s sensations. Cardiac signals travel with somatic nerves into spinal segments that also receive input from the chest wall, neck, and the left arm. Because of this convergence, the brain interprets the heart’s pain as coming from those somatic regions. That’s why the most common sites are the anterior neck, the upper part of the chest, and the left upper extremity. Pain in the posterior thigh and calf, the facial region, or the pelvic area isn’t typical for heart-origin pain since those areas involve different nerve pathways and dermatomal patterns. In short, heart-related pain is commonly felt in the front of the chest and left-sided neck/arm region.
