Fatigue

It is a common heart attack symptom in women. Altogether, their shortness of breath, fatigue, and general malaise may lead women to think they are having flu-like symptoms instead of a heart attack. However, they should be careful to note symptoms that definitely point out that something is not right. The sudden and unexpected onset of symptoms should also raise concern.
Heart attacks are a source of metabolic and physical stress to the organism. The heart tries to overcome the injury by pumping harder to provide more blood flow to the area, which sometimes results in worsening of the symptoms. Thus, if you start feeling exhausted all of a sudden and for no reason, this should be an alarm sign if you’re a woman with an underlying heart problem.
In some cases, fatigue is a prodromal sign of a heart attack, which means it is perceived a few days before the onset of the cardiac event. That’s not always the case, but if you have this symptom, it is a good idea to ask your doctor and get a full physical exam with lab tests to know what’s going on.
