What does a blockage feel like?

So, a heart blockage isn’t actually a blockage of the heart, it’s a blockage of the blood vessels that supply the heart, which are called the coronary arteries. So heart blockage, heart attack, coronary, they’re all referring to exactly the same thing, and what it feels like is the sudden onset of severe chest pain, with breathlessness and sweating.
