The challenge of a heart attack is deciding that symptoms all add up to a serious event. Each one can be attributed to non-serious conditions. If you experience more than one symptom, have it check out.
People are also unwilling to disturb emergency workers. Most EMTs and firefighters don’t mind getting called out because you never know. They would rather roll on a mistake than try to revive a corpse.
Put the odds in your favor. Workout, eat right, stop smoking, and control your cholesterol. You’ll feel better in the long run and may stave off a heart attack.
