Aortic Dissection Leading to Two Myocardial Infarctions A Rare but Fatal Case

Introduction: Aortic dissection is a life-threatening condition that can lead to severe cardiac complications. A recent case study highlights how this rare but catastrophic event resulted in two consecutive myocardial infarctions. Understanding such cases is crucial for early diagnosis and management.

Case Summary: A 56-year-old obese male with a history of hypertension was admitted with sudden right-sided chest pain radiating to his right shoulder and arm. Initial electrocardiography (ECG) findings suggested an inferior ST-segment elevation myocardial infarction (STEMI). He was treated with standard thrombolytic therapy, resulting in symptom relief. However, within 30 minutes, he developed left-sided chest pain and ECG changes indicating an anterior STEMI. Coronary angiography later revealed a long dissection in the left circumflex artery (RCX) and an occluded left anterior descending artery (LAD), ultimately leading to a Stanford Type A aortic dissection. Despite emergency transfer for surgical intervention, the patient succumbed to refractory cardiogenic shock.

Understanding the Clinical Significance:

• Early Diagnosis is Critical: Diagnosing aortic dissection is challenging as symptoms often mimic myocardial infarction. Physicians must consider aortic dissection in cases presenting with atypical chest pain and fluctuating ECG changes.
• Management Complexity: Coronary malperfusion complicates type A aortic dissection and increases mortality risk. Surgical intervention combined with aggressive coronary revascularization remains the best approach.
• Insights from Medical Research: Studies suggest that patients with type A aortic dissection and coronary malperfusion have significantly higher mortality rates. The American Heart Association (AHA) emphasizes the need for rapid imaging techniques to differentiate between myocardial infarction and aortic dissection.

Key Takeaways:

• Aortic dissection should be a differential diagnosis in patients with fluctuating ST-segment elevations.
• Immediate imaging and a multidisciplinary approach are essential for effective management.
• Antiplatelet and thrombolytic therapy should be used cautiously when aortic dissection is suspected.
