Relationship between carotid atherosclerosis and lipoprotein (a) in patients with acute ischemic stroke.

Objective: This study aimed to examine the relationship between lipoprotein (a) (Lp[a]) and other blood lipid indexes and carotid artery atherosclerosis in patients with acute ischemic stroke (AIS).

Methods: A total of 2,018 patients were selected from the hospital "acute stroke intervention and secondary prevention registration database" by identifying blood fat indexes (cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and Lp[a]). Based on the results of carotid artery ultrasound examinations, the patients were divided into a "no plaque" group, comprising 400 patients, a "plaque and no stenosis" group, comprising 1,122 patients and a "carotid stenosis" group, comprising 496 patients.

ECAS progression score: a web-based model to predict progression of extracranial carotid artery stenosis.

Background And Purpose: To develop and validate a risk model (Extracranial Carotid Artery Stenosis progression score, ECAS-PS) and to predict risk of ECAS progression.

Methods: The ECAS-PS was developed based on the Renqiu Stroke Screening Study (RSSS), in which eligible participants were randomly divided into derivation (60%) and validation (40%) cohorts. ECAS at baseline and follow-up was diagosed by carotid duplex ultrasound according to the published criteria.

ECAS score: a web-based risk model to predict moderate and severe extracranial carotid artery stenosis.

Background and purpose To develop and validate a risk model (Extracranial Carotid Artery Stenosis score, ECAS score) to predict moderate and severe ECAS. Furthermore, we compared discrimination of the ECAS score and three existing models with regard to both moderate and severe ECAS. Methods The ECAS score was developed based on the Renqiu Stroke Screening Study (RSSS), in which eligible patients were randomly divided into derivation (60%) and validation (40%) cohorts.

[A study on the relationship between metabolic syndrome and anterior cerebral infarction].

Objective: To study the relationship between metabolic syndrome (MS) and anterior circulation infarction (ACI).

Methods: 271 ACI patients (166 men and 105 women) who fulfilled the diagnostic criteria of China Guideline for Cerebrovascular Disease Prevention and Treatment were enrolled. 147 control subjects (67 men and 80 women) without the clinical signs of cerebral infarction but with detailed case history, physical examination and CT or MRI were also selected.

[Analysis of the changes in aortic root dimension in patients with anterior cerebral infarction].

Objective: To analyze the relationship between aortic root dimension (ARD) and anterior circulation infarction (ACI) by measuring ARD of ACI patients.

Methods: The ARD of 110 ACI patients (56 men and 54 women) were measured with 2-dimensional ultrasonography during ventricular systole. 66 control subjects (32 men and 34 women) without the clinical signs of cerebral infarction or organic heart disease and cardiac insufficiency were selected after carrying out detailed case history inquiring, physical examination, CT or MRI and ultrasonic examination.
