It doesn't necessarily go the other way around, the problem is that both pains come from the same area, and often times get confused.
Any chest pain
should be thoroughly assesed, the older you get the more important that becomes.
Gas can cause discomfort, but it is usually located right in the middle of the chest, and doesn't travel anywhere (shoulders etc.) Chest pain from angina
or a heart attack
may or MAY NOT travel anywhere. If you are having chest pain that radiates to the shoulders or neck, get it checked. If you are having pain in the middle of the chest that DOES NOT radiate, get it checked.
In other words there is no way to differentiate between the two without lab work
