Early diagnosis of pulmonary thromboembolism (PTE) is crucial in clinical medicine. Many para-clinical measurements are used to diagnose PTE.
The present study was conducted to evaluate platelet indices in terms of diagnosing PTE.
The present case-control study was conducted between May 2015 to July 2016 with 173 patients suspected of PTE in the emergency wards of Shahid Madani Hospital and Imam Reza Hospital affiliated to Tabriz University of Medical Sciences, Iran. The patients' platelet indices were checked upon admission and they were evaluated in terms of diagnosing PTE. Platelet indices included mean platelet volume (MPV), platelet distribution width (PDW) and plateletcrit (PL-CR). PTE was diagnosed in 125 out of the 173 patients. Platelet indices were also compared between two groups.
No statistically significant differences were observed between the two groups in term of demographic variables (p>0.05). MPV was found to be 10.38±8.59 in the case group and 9.46±1.11 in the controls (p>0.05). PDW was also found to be 12.86±5.57 in the case group and 12.32±2.48 in the controls (p>0.05). Moreover, PL-CR was found to be 22.59±7.32 in the case group and 21.97±8.16 in the controls (p>0.05).
According to the obtained results, platelet indices do not increase in PTE. They cannot be therefore used to diagnose PTE in suspected patients.
肺血栓栓塞症（PTE）的早期诊断在临床医学中至关重要。许多临床旁测量方法被用于诊断PTE。
本研究旨在评估血小板指标在诊断PTE方面的作用。
本病例对照研究于2015年5月至2016年7月在伊朗大不里士医科大学附属沙希德·马达尼医院和伊玛目·礼萨医院的急诊病房对173例疑似PTE患者进行。患者入院时检查血小板指标，并对其进行PTE诊断评估。血小板指标包括平均血小板体积（MPV）、血小板分布宽度（PDW）和血小板压积（PL-CR）。173例患者中有125例被诊断为PTE。还比较了两组之间的血小板指标。
两组在人口统计学变量方面未观察到统计学显著差异（p>0.05）。病例组MPV为10.38±8.59，对照组为9.46±1.11（p>0.05）。病例组PDW为12.86±5.57，对照组为12.32±2.48（p>0.05）。此外，病例组PL-CR为22.59±7.32，对照组为21.97±8.16（p>0.05）。
根据所得结果，PTE患者的血小板指标并未升高。因此，它们不能用于诊断疑似患者的PTE。
