Objective: To evaluate serum copeptin levels in acute pulmonary embolism (APE) patients and healthy controls and to determine the role of the serum copeptin level in the diagnosis and severity of APE.
Methods: This prospective, case-control study was conducted in the Department of Chest Diseases. Fifty patients newly diagnosed with pulmonary embolism and 39 healthy individuals were enrolled. The diagnosis of APE was confirmed by computed tomography angiography. Copeptin levels were evaluated in both groups. All APE patients were evaluated with echocardiography to identify right ventricular dysfunction and to measure the pulmonary artery systolic pressure (PASP). Patients with APE were classified according to the risk of early mortality. The correlation between early mortality risk and PASP and copeptin levels was evaluated in patients with APE.
Results: There was no significant difference between the APE and control groups in age or gender (both, p>0.05), and serum copeptin levels were similar between the two groups (p=0.309). The relationship between serum copeptin levels and early mortality risk and PASP in the APE group was also evaluated. There was no correlation between early mortality risk and serum copeptin levels and PASP.
Conclusion: The serum copeptin level, which is an important prognostic marker for cardiovascular diseases, may not be a suitable biomarker for APE.
