Abstract: Sarcoidosis is a multi-system inflammatory disorder with the characteristics of non-caseating granulomas, which is most commonly involved in lungs, heart, eyes, skin, and other organs. Symptomatic cardiac involvement is found in about 2%~5% of sarcoidosis patients. However, autopsy studies have detected that approximately 25%~50% of sarcoidosis patients have asymptomatic cardiac involvement with a delayed diagnosis and poor prognosis. We report the clinical manifestations, laboratory examinations, diagnostic methods, and treatment of one sarcoidosis patient with latent cardiac involvement, to remind clinicians to pay attention to the systematic evaluation of sarciodosis.
