Severe Fetal Distress and Placental Damage Might Be Associated with High Troponin I (cTnI) Levels in Mothers

摘要

Patient: Female, 40 Final Diagnosis: cTnI elevation of unknown etiology Symptoms: Epigastric pain Medication: — Clinical Procedure: — Specialty: Obstetrics and Gynecology Objective: Unknown ethiology Background: Troponin I is the gold standard for the diagnosis of adult acute coronary syndrome. Although it is known that a hypoxic fetus may produce cTnI, fetal cTnI passage in maternal blood has never been documented. Case Report: We report a case where the rise of cTnI in the blood of a pregnant woman was not related to maternal heart disease. Instead, it might be suggestive of a fetal cardiac origin, as there was a severe placental insufficiency with a fetal intrauterine growth restriction. Conclusions: This study suggests that the rise of cTnI in maternal blood in a cardiovascular healthy pregnant woman might have a fetal origin. After having excluded any maternal causes, cTnI elevation could be explained with the transfer of fetal cTnI through an injured placenta.
