10 Heart Attack Symptoms

7. Exhaustion

Extreme tiredness may be a sign of underlying heart problems. This is more likely if the fatigue happens after one does something they were previously able to do without getting tired, such as climbing stairs or taking a walk. Some people experience exhaustion even upon waking up in the morning. This may also interfere with one's ability to perform daily tasks. This kind of exhaustion, when associated with a heart attack, is due to the heart working harder to pump the same amount of blood. The energy this burns results in fatigue and drowsiness.
