Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of heart attacks in young women. Clinicians often observe a significant link between SCAD and oral contraceptives, particularly in patients without traditional risk factors. A recent case report highlights a 32-year-old woman who experienced an acute myocardial infarction (AMI) while taking combined hormonal birth control for four months.
While the exact mechanism remains unclear, hormonal factors significantly influence arterial wall integrity. Consequently, the high estrogen states associated with SCAD and oral contraceptives may predispose individuals to intimal tears or intramural hematomas. In this specific case, the patient presented with acute chest pain and ST-segment elevation. Coronary angiography initially showed diffuse narrowing of the left anterior descending (LAD) artery. However, the condition improved after intracoronary nitroglycerin administration. Subsequent optical coherence tomography (OCT) confirmed an intramural hematoma, which is a hallmark of SCAD.
Early identification is crucial for achieving favorable outcomes in young female patients presenting with acute coronary syndrome. Therefore, physicians must maintain a high clinical suspicion of SCAD when traditional atherosclerotic risks are absent. In this case, the medical team opted for conservative management rather than invasive stenting. Follow-up imaging at six weeks showed significant healing of the vessel. Furthermore, the patient recovered fully with normalized left ventricular function at the one-year mark. This outcome supports the current preference for non-invasive strategies in stable SCAD patients.
Exogenous hormones can alter the proteoglycan composition and collagen synthesis within the arterial media. These changes potentially weaken the vessel wall, making it susceptible to spontaneous dissection under stress.
While coronary angiography is the first step, advanced intravascular imaging like Optical Coherence Tomography (OCT) or Intravascular Ultrasound (IVUS) provides definitive evidence of intramural hematomas or false lumens.
Typically, clinicians recommend discontinuing systemic hormonal contraceptives after a SCAD event. Patients should instead consider non-hormonal alternatives or progestin-only intrauterine devices to minimize recurrence risks.

An 11-year Swedish registry study of 618 uterine sarcoma patients found that minimally invasive surgery yielded survival comparable to open surgery in early stages. However, adjuvant chemotherapy conferred no survival benefit in localized or advanced disease, highlighting stage and histology as key outcomes.
