As an anatomically correct heart emoji, it's useful when talking about science or medicine. It's also used to express more serious and deeper emotions than the symbol of love (❤️).

In the West, it's sometimes used for intense confessions on Valentine's Day, like "I give you my heart." K-pop fans often use this emoji to convey vivid emotions when reacting intensely to an idol's amazing performance, as if to say, "My heart is about to stop."
