Relationship between annular calcification of plaques in the carotid sinus and perioperative hemodynamic disorder in carotid angioplasty and stenting

Objective: To investigate the correlation between annular plaque calcification in the carotid sinus and perioperative hemodynamic disorder (HD) in carotid angioplasty and stenting (CAS).MethodsThe clinical data of 49 patients undergoing CAS due to narrowing of the carotid sinus were retrospectively analyzed. All patients had preoperative carotid computed tomography angiography (CTA) and were divided into HD and non-HD groups based on the occurrence of HD in the perioperative period of CAS. HD was defined as persistent bradycardia (heart rate < 60 beats per min) or persistent hypotension (systolic blood pressure < 90 mmHg) in the perioperative period and lasting for at least 1 h. The baseline data, including the degree of carotid artery stenosis, plaque length, plaque thickness, calcified plaque morphologies (i.e., plaque circumferential angle: < 90° defined as dotted calcification; 90°–180° defined as arcuate calcification; > 180° defined as annular calcification), contralateral carotid artery conditions, balloon diameter, and stent types, were compared between the two groups. Binary logistic regression was used to analyze the risk factors for the occurrence of HD.ResultsAmong the 49 patients undergoing CAS, 14 (28.57%) developed perioperative HD, and 35 did not. Annular calcification was more common in the patients in the HD group than in the non-HD group. No significant differences in the probabilities of dotted and arcuate calcifications were found between the two groups (p > 0.05). The duration of continuous dopamine consumption in the HD group was 9–71 h. The average hospital stay of the HD group (10.14 ± 4.17 days) was significantly longer than that of the non-HD group (6.57 ± 1.9 days; p < 0.001). Patients in the HD group had significantly more pronounced lumen stenosis (p = 0.033) and longer plaque length (p = 0.034) than those in the non-HD group. After adjusting for age and sex, multivariate regression analysis showed that the presence of annular plaque calcification was an independent predictor of HD (odds ratio: 7.68, 95% confidence interval: 1.46–40.37, p = 0.016).ConclusionsThe occurrence of annular plaque calcification in the carotid sinus was an independent risk factor for perioperative HD in CAS. Preoperative carotid CTA assists with the early identification of high-risk patients who may develop HD.     

The impact of non-motor symptoms on the Health-Related Quality of Life of Parkinson's disease patients from Southwest China

BackgroundThe impact of non-motor symptoms (NMS) on the Health-Related Quality of Life (HRQoL) of patients with Parkinson's disease (PD) in the Chinese population are largely unknown.ObjectivesTo study the impact of NMS on the HRQoL in Chinese PD patients.MethodsA total of 693 PD patients from Southwest China were included in the study. NMS of patients were evaluated by non-motor symptoms scale (NMSS) and Parkinson's disease questionnaire-39 item version (PDQ-39) was used to evaluate the HRQoL of PD.ResultsThe mean total score of NMSS was 37.2 ± 33.0 and the most prevalent NMS domain was sleep/fatigue (79.8%). There was a significant strong positive correlation between total NMSS score (r_s = 0.71, P < 0.01), sleep/fatigue domain (r_s = 0.60, P < 0.01) and PDQ-39 SI. Mood/apathy (r_s = 0.55, P < 0.01), attention/memory (r_s = 0.42, P < 0.01), gastrointestinal (r_s = 0.44, P < 0.01) and Miscellany domains (r_s = 0.46, P < 0.01) moderately correlated with PDQ-39 SI. A strong correlation was found between PDQ-39 SI (r_s = 0.71, P < 0.01), emotional well-being (r_s = 0.62, P < 0.01), cognitions (r_s = 0.62, P < 0.01), and the total score of NMSS. Moderate correlation was found between mobility (r_s = 0.45, P < 0.01), activities of daily living (r_s = 0.43, P < 0.01), stigma (r_s = 0.42, P < 0.01), communication (r_s = 0.47, P < 0.01), bodily discomfort (r_s = 0.46, P < 0.01) and the total score of NMSS. Female, H–Y stage, UPDRS-III and NMSS total score were the potential determinants of worse HRQoL of PD patients.ConclusionsNMS have close association with various aspects of the HRQoL. Severe NMS may be related to dramatic decline of the HRQoL of PD patients.

Low serum miR-320b expression as a novel indicator of carotid atherosclerosis

We aimed to investigate correlation of carotid plaque with serum microRNA level and provide a potential mechanism for ischemic stroke prevention. Fasting serum was obtained from 177 patients with carotid plaques diagnosed using B ultrasound and 155 healthy subjects for RNA extraction and measurement of glucose, lipid and related biochemical indices. microRNAs level was assayed using microarray, validated using real-time PCR and statistically analyzed for their correlation with relevant clinical information. Statistical analyses showed significant differences between control and plaque groups in age, smoking history, and histories of cerebrovascular diseases, blood pressure, diabetes and coronary diseases. Patients in plaque group had significantly higher LDL-C level but significantly lower miR-320b level than healthy subjects. The P50 (P₂₅–P₇₅) of miR-320b was 2.38 (1.46–3.80) in control group and 1.20 (0.80–2.01) in plaque group (P = 0.000), as well as 1.39 (0.83–2.08) in stable plaque group and 0.77 (0.590.99) in vulnerable plaque group (P = 0.000). The area under the ROC curve of traditional factors, miR320b with traditional factors, traditional factors with plaque diameter, and traditional factors with IMT for patients with carotid plaques was 0.710, 0.834, 0.826 and 0.808, respectively. This study suggests that miR-320b is a specific serum marker of carotid atherosclerosis and vulnerable plaque, and its combination with traditional factors is the best means for diagnosis of cerebrovascular diseases. The carotid atherosclerosis complicated with vulnerable plaque is a high risk factor for cerebral infarction. B-ultrasound examination combined with serum miR-320b expression and traditional indices could be used to predict subjects with high-risk for ischemic stroke.     

老年急性脑梗死患者血浆同型半胱氨酸水平与颈动脉粥样硬化的关系

目的探讨老年急性脑梗死(ACI)患者血浆同型半胱氨酸(Hcy)水平与颈动脉粥样硬化(CAS)斑块及其硬化程度的关系。方法93例确诊的ACI患者均接受颈动脉彩色多普勒超声仪检查,测量左右颈总动脉内-中膜厚度(IMT),根据测量结果分为有CAS斑块组(60例)和无CAS斑块组(33例);将患者CAS程度分为0～4级。采用循环酶法检测两组ACI患者血浆Hcy水平,对血浆Hcy水平与CAS的斑块及其硬化程度分级进行相关性分析。结果老年ACI患者有CAS斑块组血浆Hcy浓度[18.83(15.20～24.03)μmol/L]明显高于无CAS斑块组[12.30(9.70～15.10)μmol/L](P<0.05);且有CAS斑块组高Hcy血症发生率(36.67%)较无CAS斑块组(12.12%)显著增高(P<0.05)。CAS程度:0级组、1级组分别与3级组,0级组、1级组、2级组分别与4级组的血浆Hcy水平比较差异有统计学意义(均P<0.005)。结论老年ACI患者中,CAS斑块形成可能与血浆Hcy水平升高有关;CAS程度愈高,其相关性愈大。     

颈动脉狭窄患者同型半胱氨酸与肌红蛋白、尿酸的相关性分析

目的 研究颈动脉狭窄患者血清同型半胱氨酸(HCY)与肌红蛋白(Mb)、尿酸(UA)的相关性。方法 收集158例颈动脉狭窄患者(CAS组)、136例健康人(对照组)血液标本,采用循环酶法检测血浆HCY水平,胶乳增强免疫透射比浊法测定Mb水平,酶比色法测定UA水平。结果 CAS 组HCY、Mb、UA的水平均较对照组升高(P均<0.05),CAS组HCY与Mb、UA水平呈正相关(r=0.438,0.476,P均<0.05)。结论 HCY水平变化与Mb、UA水平有关,三者与颈动脉狭窄的发生密切相关。
