Abstract
Background
Acute pancreatitis can rarely present with electrocardiographic changes that imitate myocardial ischemia. Even rarer is for acute pancreatitis to present with ST-segment elevation in contiguous leads, suggestive of an acute coronary syndrome. In this comprehensive review article, we highlight diagnostic challenges and examine possible pathophysiological causes as seen through 34 total cases in which acute pancreatitis has been found to mimic an acute myocardial infarction.
Summary
It has been shown that regardless of the severity of acute pancreatitis, it can be associated with myocardial injury of varying presentation. Thus far, there have been 34 total cases where acute pancreatitis presented with electrocardiographic changes consistent with acute myocardial infarction without true coronary artery thrombosis. An inferior wall ST-elevation myocardial infarction pattern was the most frequently demonstrated. Many hypotheses have been proposed as to the mechanism of injury including decreased coronary perfusion, direct myocyte damage by pancreatic proteolytic enzymes, indirect parasympathetic injury, electrolyte derangements, and coronary vasospasms. Given the complexity of the clinical presentation, thorough subjective and objective evaluation can be vital in guiding diagnosis and possibly more invasive testing.
Key Messages
It is imperative that clinicians are aware that acute pancreatitis can mimic an acute myocardial infarction. Although we have started to better understand the pathological mechanisms for this phenomenon, further research focused on specific molecular target areas is needed.
