What is a common complication associated with myocardial infarction that manifests as inflammation?

Dressler's syndrome is a recognized complication that can occur following a myocardial infarction, characterized by a post-myocardial inflammatory response. This syndrome typically presents as pericarditis, which is an inflammation of the pericardium, the fibrous sac surrounding the heart. It usually arises several weeks to months after the initial cardiac event and is believed to be an autoimmune reaction to myocardial antigens that may be exposed following tissue damage.

This inflammatory response can result in symptoms such as chest pain, fever, and a pericardial rub upon examination. The understanding of Dressler's syndrome is vital for cardiac sonographers, as they may be tasked with evaluating patients for pericardial effusion or other complications that arise from this inflammatory process.

The other options do not specifically manifest as a post-myocardial inflammation syndrome in the same way. Cardiomyopathy involves changes to the cardiac muscle rather than an inflammatory process. Angina pectoris is more of a symptom related to ischemia rather than a complication arising from a myocardial infarction, and heart failure signifies a state of reduced cardiac function rather than an inflammatory response.
