10 Heart Conditions That Present Differently in Women

5. Spontaneous Coronary Artery Dissection - The Young Woman's Heart Attack

Spontaneous coronary artery dissection (SCAD) represents a devastating cause of heart attack that predominantly affects young, otherwise healthy women, often during or shortly after pregnancy. This condition involves a spontaneous tear in the coronary artery wall that creates a false channel, blocking blood flow to the heart muscle without the typical atherosclerotic plaque buildup seen in traditional heart attacks. SCAD accounts for up to 35% of heart attacks in women under 50 and is the leading cause of pregnancy-associated myocardial infarction. The condition often strikes without warning in women who have few or no traditional cardiac risk factors, making it particularly shocking for both patients and healthcare providers. Symptoms typically include severe chest pain that may radiate to the arm, neck, or jaw, often accompanied by shortness of breath, nausea, and sweating. The pain is usually sudden in onset and severe, distinguishing it from the more gradual symptom progression seen in traditional coronary artery disease. Risk factors include pregnancy (particularly the postpartum period), fibromuscular dysplasia, connective tissue disorders, and extreme physical or emotional stress. Hormonal fluctuations, particularly the dramatic changes in estrogen and progesterone levels during pregnancy and the postpartum period, are thought to weaken arterial walls and predispose women to dissection. Diagnosis requires high-resolution imaging, and treatment differs significantly from traditional heart attack management, often favoring conservative medical therapy over invasive interventions to allow the artery to heal naturally.
