An enlargement or dilation of the heart, particularly an abnormal increase in heart size.
From Greek 'kardia' (heart) + 'auxe' (increase, growth), describing pathological cardiac enlargement.
A enlarged heart sounds like it would be stronger, but it's actually the opposite—the more it stretches, the weaker it pumps, like an overstretched rubber band that can't snap back.
