An irrational and persistent fear of heart disease, heart attacks, or having cardiac problems.
From Greek 'kardia' (heart) + 'phobos' (fear). This phobia name was formalized in psychological terminology in the late 1800s to describe cardiac-specific anxiety.
Ironically, the stress and anxiety from cardiophobia can actually harm the heart through the mind-body connection—people's fears about their hearts can literally trigger the heart problems they fear.
