1 doctor agrees
In brief: Depends
Depends upon extent and location of the attack.
Heart attack occurs when blood supply is inadequate for the metabolic needs of the heart. When this occurs for a prolonged period pieces of the heart die. If this piece is very large ( like occlusion of the main vessel) or is located in a critical area ( such as the electrical centers) - game over!

In brief: Heart attack
Is very common cause of sudden death.
The early ischemia of the heart muscle can trigger a life ending rhythm(usually ventricular fibrillation). On the other hand if that doesn't happen but a large mass of muscle dies, the ensuing shock or heart failure can kill days or longer later.
