The present study aimed to determine cardiac troponin I (CTnI) variation trends in patients with acute PE referred to Rajaie Cardiovascular Medical and Research Center.   Methods: This cross-sectional descriptive-analytical study consecutively enrolled 54 patients with acute PE. Variation trends of CTnI were measured in the study population at 5 different time points: upon admission and subsequently 8, 24, 48, and 72 hours post-admission. The relationships between CTnI variation trends and computed tomography angiography, echocardiography, and electrocardiography findings were investigated. CTnI variation trends were compared between a group undergoing catheter-directed thrombolysis (CDT) and a group receiving the conventional anticoagulant treatment. The data were analyzed using the SPSS software, version 20.   Results: A reduction was observed in the CTnI variation trends of all the samples. Both groups exhibited a decline in CTnI levels, but the slope of this reduction was steeper in the CDT group (P=0.04). Additionally, a significant relationship was also detected between CTnI reduction and right ventricular function improvement (P=0.04). No significant association was observed between systolic pulmonary artery pressure changes and CTnI variation trends.   Conclusions: The results indicated a significant relationship between reduced CTnI levels and improved right ventricular function. Additionally, the CDT group showed a significant fall in the CTnI level compared with the anticoagulant-only group.
