Husband was just released from hospital following tests for c/o chest pain with breathing, fatigue, low-grade fever and night sweats. Echo, stress test and CT show mild pleural effusion, "fluid" around heart and a "shadow". Also, the hemoglobin was 11, hematocrit 32, iron 25 and CPK elevated. He was discharged with recommendation of cardiac cath to investigate shadow and med to treat pericarditis. No mention of the low iron. Should we be concerned about bleeding somewhere?
