Lack of sensation or numbness affecting the heart region; reduced or absent feeling in the cardiac area.
From Greek 'kardia' (heart) + 'an-' (without) + 'aesthesis' (sensation, from 'aisthanesthai' to perceive). This combines the negating prefix with the root for sensation, creating a medical term for lost feeling.
The 'an-' prefix meaning 'without' is a time machine in medicine—anesthesia (without sensation), anemia (without blood), and anoxia (without oxygen) all date to eras when doctors described disease by what was missing.
