Pericarditis and Post-cardiac Injury Syndrome as a Sequelae of Acute Myocardial Infarction

Purpose of Review: Pericarditis secondary to acute myocardial infarction (AMI) is known to develop either immediately or after a latent period of few months. Due to varied presentation and timing, its diagnosis and treatment can be challenging. This article reviews underlying mechanisms and the role of cardiac imaging in investigating and managing this condition. Recent Findings: Timely diagnosis of pericarditis after AMI is important to prevent potential progression to complicated pericarditis. Clinical suspicion warrants initial investigation with serum inflammatory levels, electrocardiogram, and echocardiography. When findings are inconclusive, cardiac magnetic resonance imaging and computerized tomography can provide additional diagnostic information. Summary: Pericarditis after AMI is a treatable condition. Clinicians should maintain a high suspicion in this era of revascularization and develop a strategic plan for timely diagnosis and management.
