A cockle is a type of shellfish. I don’t know how the association with the heart was formed, but it must be old—the Latin name for the order is “Cardiida”.
Cockles are literally heart shaped when viewed side on. The cardioid in mathematics gets its name from the same thing and that’s bulbous by comparison.
Wiktionary also suggests that “cockles” may be a corruption of cochlea(e) which is one of at least a couple of names for the heart’s ventricles.

I will tell my crush that looking at her makes my cockles bulbous and report back what happens.
Crush no longer speaking to me.
