What would happen if I stabbed my heart with a knife?

I've self-harmed with a knife before, poking myself with it in the heart, but if I succeeded, with it, what would happen?

A stab wound can be worse than a gunshot wound depending on the location. If the stab hits a vase and the shot doesn't, it could be worse. Blunt heart injury is a blow to the chest that injures the heart muscles, lacerates (ruptures) the walls of the heart, or damages a heart valve. People may feel like their heart is pounding or racing, feel short of breath, or have dangerously low blood pressure. In other words, you die if you're lucky.

Will probably have more luck stabbing your neck, requires some serious motivation though.
