Association Between Plasma Fibrinogen Level and the Risk of Myocardial Infarction With Non-Obstructive Coronary Arteries: A Retrospective Observational Study

Lower plasma fibrinogen levels were independently associated with the occurrence of MINOCA, suggesting a potential role in its pathophysiology and the early identification of this condition. Fibrinogen alone has limited discriminative utility; however, fibrinogen may contribute to multi-marker approaches for determining and managing MINOCA patients.
