摘 ? 要:目的 ?初步探討H型高血壓與腔隙性腦梗死患者血流動力學變化的影響。方法 ?選取2017年3月~2018年4月在亳州市人民醫院就診的腔隙性腦梗死患者90例,依據血漿同型半胱氨酸水平及是否伴有高血壓,將腔隙性腦梗死患者分成H型高血壓組47例和非H型高血壓組43例。利用頸部血管彩超評價入組患者的頸部血流動力學狀態,比較兩組患者血流動力學參數的差異。結果 ?H型高血壓組患者Vmax[(31.23±6.75)cm/s vs (34.53±4.23)cm/s]、Vmin[(5.24±2.01)cm/s vs (8.44±1.40)cm/s]、Vmean[(12.71±3.03)cm/s vs (16.81±2.17)cm/s]、Qmean[(7.37±1.43)ml/s vs (8.38±1.04)ml/s]均低于非H型高血壓組,差異具有統計學意義(P<0.05)。H型高血壓組患者PI(2.08±0.32 vs 1.56±0.21)和RI(0.84±0.45 vs 0.75±0.21)均高于非H型高血壓組,差異具有統計學意義(P<0.05)。結論 ?H型高血壓顯著降低腔隙性腦梗死患者的血流速度,H型高血壓是腔隙性腦梗死患者的危險因素。

Abstract:Objective ?To investigate the effects of hemodynamic changes in patients with H-type hypertension and lacunar infarction. Methods ?A total of 90 patients with lacunar infarction who were admitted to the People's Hospital of Bozhou city from March 2017 to April 2018 were enrolled. Patients with lacunar infarction were divided according to plasma homocysteine level and hypertension. There were 47 patients with H-type hypertension and 43 patients with non-H-type hypertension. The cervical hemodynamic status of the patients was evaluated by cervical vascular ultrasonography, and the differences in hemodynamic parameters between the two groups were compared. Results ?Vmax in patients with H-type hypertension [(31.23±6.75) cm/s vs (34.53±4.23) cm/s], Vmin[(5.24±2.01) cm/s vs (8.44±1.40) cm/s], Vmean [(12.71±3.03) cm/s vs (16.81±2.17) cm/s], Qmean [(7.37±1.43) ml/s vs (8.38±1.04) ml/s] were lower than non-H type hypertension group, the difference was statistically significant (P<0.05). Patients with H-type hypertension had higher PI (2.08±0.32 vs 1.56±0.21) and RI (0.84±0.45 vs 0.75±0.21) than non-H-type hypertension group, the difference was statistically significant (P<0.05). Conclusion ?H-type hypertension significantly reduces the blood flow velocity in patients with lacunar infarction. H-type hypertension is a risk factor for patients with lacunar infarction.

腔隙性腦梗死(lacunar infarction,LI)屬于缺血性卒中的一個重要亞型,發病率約占缺血性卒中的25%[1]。最近的研究表明,腔隙性腦梗死的近期死亡率和致殘率相對較低,復發率較高,與其他缺血性卒中具有相似的復發風險,腔隙性梗死的遠期預后不良性,發生認知功能障礙的風險增加,最終導致癡呆和死亡[2,3]。高血壓是公認的引起腔隙性腦梗死的重要危險因素[4],而我國75%原發性高血壓患者常伴有血漿同型半胱氨酸(total homocysteine,tHcy)水平升高(≥10 μmol/L),二者具有協同作用,學者把伴有血漿tHcy水平升高的高血壓稱為H型高血壓[5]。利用超聲多普勒血流探頭檢測雙側頸動脈血液循環動力學的變化,可以全面評價被檢患者腦血管床的動力學特征和血液運動狀態,綜合評估被檢查的腦血管功能狀況。本文探討H型高血壓對腔隙性腦梗死患者腦血管功能的影響,為腔隙性腦梗死患者的預防提供一定的參考。……
