Pentraxin-3 Levels Relate to the Wells Score and Prognosis in Patients with Acute Pulmonary Embolism

الملخص EN

Objective.

To investigate the value of the PTX-3 test in evaluating the prognosis of acute pulmonary embolism (APE).

Method.

117 APE patients were selected and divided into two groups according to plasma PTX-3 levels, including the group in which PTX−3≥3.0 ng/mL (n=42) and the group in which PTX−3<3.0 ng/mL (n=75).

Patients were stratified into high-risk, medium-risk, and low-risk groups according to the Wells scores, and the PTX-3 levels were compared among the groups.

Patients had been followed-up as well.

Results.

According to the Wells scores, 11 patients were classified as high-risk (9.4%) and 68 were medium-risk (58.1%), while 38 were low-risk (32.5%).

The PTX-3 levels in different risk groups were statistically different (all P<0.05).

During the follow-up period, 6 deaths occurred in the group with elevated PTX-3 (≥3.0 ng/mL), while 2 deaths occurred in the group with nonelevated PTX-3 (<3.0 ng/mL).

The difference between the two groups was statistically significant (P<0.01).

13 patients were hospitalized due to recurrent pulmonary embolism, of which 12 were in the group with elevated PTX-3 (≥3.0 ng/mL), while 1 patient was in the group with nonelevated PTX-3 (<3.0 ng/mL).

The difference was statistically significant (P<0.01).

Conclusion.

The plasma PTX-3 level in APE patients is correlated with PE risk stratification.

There is a significant correlation between PTX-3 levels and PE-related cardiac deaths, as well as the prognosis of recurrent PE.

PTX-3 can be used as a clinical indicator of PE prognosis.
