Heart attack in men usually presents with sudden onset of central chest pain with breathlessness and sweating, but it can present as sudden collapse, and it can be silent. It can be only discovered later on when someone has a heart test for a different reason. But the classical presentation of a heart attack in a man is sudden onset of severe chest pain.
