When we think of heart attacks, we often imagine sudden, dramatic symptoms. However, for women, warning signs are frequently subtle and easy to overlook. These quieter cues—like fatigue, sleep trouble, or mild breathlessness—can emerge weeks in advance of a heart event.

One key signal is unusual fatigue. Feeling tired after a long day is normal, but exhaustion that lingers without explanation—especially if paired with shortness of breath or a rapid heartbeat during light activity—may indicate heart trouble. This kind of persistent tiredness is not to be ignored.

Another symptom is abdominal discomfort. Women may mistake upper belly pain or cramping for indigestion or menstrual cramps. However, ongoing or wave-like pain in this area could be linked to the heart, particularly if digestive causes are ruled out.
