Cardiac involvement in Churg-Strauss syndrome mimicking acute coronary syndrome

Churg-Strauss syndrome (CSS) is a rare multisystemic disorder of unknown origin and cardiac involvement is one of the most serious manifestations of the disease, accounting for approximately one-half of deaths attributable to CSS. Cardiac manifestation can be acute and mimic acute coronary syndrome (ACS). In this setting checking the blood leucocyte count can reveal hypereosinophilia and lead to a diagnosis of CSS.
