STEMI could be the primary presentation of acute aortic dissection

Area of Science:

• Cardiology
• Vascular Surgery
• Emergency Medicine

Background:

• Stanford type A aortic dissection (TAAD) can cause coronary artery complications.
• TAAD as a cause of ST-segment elevation myocardial infarction (STEMI) is not well-studied.
• This study investigates 8 cases of TAAD presenting primarily as STEMI.

Purpose of the Study:

• To analyze the clinical characteristics and outcomes of TAAD presenting as STEMI.
• To understand the incidence and diagnostic challenges of TAAD-induced STEMI.
• To highlight the importance of early diagnosis for optimal management.

Main Methods:

• Retrospective review of patients admitted for STEMI with Percutaneous Coronary Intervention (PCI).
• Analysis of clinical data from January 2002 to January 2017.
• Review of coronary angiography findings in patients with suspected coronary artery occlusion.

Main Results:

• STEMI secondary to TAAD occurred in 0.51% of STEMI cases (8/1,576).
• Coronary angiography revealed RCA compression or dissection in 3 of 5 patients unaware of TAAD.
• In-hospital mortality was 37.5% (3/8), with poorer outcomes in those not undergoing timely surgery.

Conclusions:

• TAAD presenting as STEMI is rare, predominantly involving the right coronary artery (RCA).
• Prompt diagnosis of TAAD is critical for effective STEMI management.
• High clinical suspicion and awareness are essential for timely diagnosis and improved outcomes.
