Insights
Spontaneous Coronary Artery Dissection (SCAD) can cause ST-elevation myocardial infarction (STEMI) in diverse patient groups. These cases highlight varied diagnostic and management approaches for SCAD-STEMI.
Area of Science:
- Cardiology
- Vascular Medicine
Background:
- Spontaneous Coronary Artery Dissection (SCAD) is an underdiagnosed cause of myocardial infarction, particularly in younger individuals.
- ST-elevation myocardial infarction (STEMI) in the context of SCAD presents unique diagnostic and therapeutic challenges.
Observation:
- Two patient cases illustrate SCAD-STEMI: a female treated with intravascular imaging and PCI, and a male initially managed conservatively due to missed diagnosis.
- SCAD-STEMI can manifest differently, affecting not only young women without traditional risk factors.
Findings:
- Intravascular imaging (IVUS) aids SCAD diagnosis and guides percutaneous coronary intervention (PCI).
- Conservative management may be initially chosen for SCAD-STEMI, but invasive strategies and anticoagulation might become necessary.
- SCAD pathophysiology and diagnostic methods are crucial for appropriate patient care.
Implications:
- Recognizing SCAD-STEMI's diverse presentations is vital for timely and accurate diagnosis.
- Management strategies for SCAD-STEMI must be individualized, considering potential risks of invasive treatments.
- Further research into SCAD's pathophysiology and optimal treatment protocols is warranted.
Abstract:
In this paper, we present 2 patients with ST-elevation myocardial infarction in the course of Spontaneous Coronary Artery Dissection. The first patient, a female admitted with STEMI, was diagnosed with SCAD with intravascular imaging and treated with IVUS-guided PCI. In the second patient, a young male hospitalized due to angina and STEMI, SCAD was not identified initially, and the patient was treated conservatively. Based on these cases, we show different faces of the same disease that imply different diagnostics and management strategies. We draw attention to the fact that the disease affects not only young women without atherosclerotic risk factors and that it is not always possible to avoid generally not recommended invasive treatment and anticoagulant therapy. The paper also discusses the disease's pathophysiology and its diagnosis methods.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
