C-reactive protein, a well known marker of inflammation is being investigated as a probable marker of predicting acute cardiovascular events and its severity. The aim of the present study was to assess the possible role of highly-sensitivity C-reactive protein (hs-CRP) in predicting short-term functional outcome of ischemic stroke.
A prospective study was conducted on subjects admitted with first attack of confirmed ischemic stroke. It included 50 male and 52 female. Serum hs-CRP was measured in the 2(nd) (CRP-D2) and 5(th) days (CRP-D5) post-stroke. Modified Rankin scale (MRS) was measured in all subjects in the 2(nd) (MRS-D2), 5(th) days (MRS-D5) and also 3 month (MRS-M3) after stroke to assess the short-term functional outcome and mortality of subjects.
The mean age of the patients was 71.75±11.44 years. The mortality rate was 47.1% in the third months after stroke. There was no significant correlation between CRP-D2 and MRS-M3 and also between CRP-D5 and MRS-M3 (P>0.05). However there was a significant association between high CRP-D2 (CRP>3) and MRS-M3 and also between high CRP-D5 and MRS-M3 (P<0.005).
This study showed that the value of CRP by itself could not predict the severity of short-term functional disability and it might not be useful as a clinical tool for predicting outcome.
C 反应蛋白(CRP)是一种众所周知的炎症标志物,目前正在被研究作为预测急性心血管事件及其严重程度的可能标志物。本研究旨在评估高敏 C 反应蛋白(hs-CRP)在预测缺血性脑卒中短期功能结局中的可能作用。
对首次确诊为缺血性脑卒中的患者进行前瞻性研究。共纳入 50 名男性和 52 名女性。分别在卒中后第 2 天(CRP-D2)及第 5 天(CRP-D5)检测血清 hs-CRP。所有患者在第 2 天(MRS-D2)、第 5 天(MRS-D5)及第 3 个月(MRS-M3)进行改良 Rankin 量表(MRS)评估,以评估患者的短期功能结局和死亡率。
患者的平均年龄为 71.75±11.44 岁。卒中后第 3 个月的死亡率为 47.1%。CRP-D2 与 MRS-M3 之间以及 CRP-D5 与 MRS-M3 之间均无显著相关性(P>0.05)。然而,CRP-D2 较高(CRP>3)与 MRS-M3 之间以及 CRP-D5 较高与 MRS-M3 之间均存在显著相关性(P<0.005)。
本研究表明,CRP 本身的数值不能预测短期功能障碍的严重程度,因此可能无法作为预测结局的临床工具。
