Research indicates that severe, unexplained fatigue is a warning sign for heart attacks in 70% of women, often appearing days or weeks before a cardiac event.
Unlike normal tiredness, heart-related exhaustion is characterized by a significant decrease from a person's baseline energy that does not improve with adequate rest.
Cardiologists note that women are more prone to coronary microvascular disease, which can cause gradual, vague symptoms that are frequently overlooked by both patients and medical professionals.
