Etiology and Prognostic Risk Factors of Intracerebral Hemorrhage in Beijing

Intracerebral Hemorrhage

There were lack of data and analysis about medical management, etiology, and long-term outcome of Intracerebral Hemorrhage (ICH) in Beijing. In this study the investigators do acute CT angiography, a non-invasive imaging method to explore etiology and prognostic risk factors of ICH. Further the investigators will aim to develop and validate a risk score for predicting 1-year functional outcome after ICH.

Evaluation of Rate of Progression With Perimetry in Newly Diagnosed Open Angle Glaucoma

GlaucomaOpen-Angle1 more

The purpose of this study is to evaluate rate of progression in newly diagnosed open angle glaucoma with different types of perimetry. Would it be possible to find the rapidly progressing individuals sooner by doing perimetry more often? Is there a difference between different types of perimetry in early glaucoma? What would be the optimal timing of perimetry in newly diagnosed glaucoma? In addition the quality of life in glaucoma patients will be evaluated with two types of questionnaires in three different time points. The enrolled patients will receive appropriate treatment according to glaucoma management guidelines.

Current Treatment Strategy of Patients With Multivessel Disease or Left Main Coronary Artery Disease...

Coronary Artery Disease

According to 2011 ACCF/AHA guideline and 2014 ESC/EACTS guideline, CABG surgery was recommended for three-vessel coronary artery disease and left main coronary artery disease in the patients with stable ischemic heart disease as class I. 2-VD with proximal left anterior descending artery stenosis was also indicated for CABG surgery as class I recommendation. However, many patients have been recommended for PCI by catheterization laboratory cardiologist; 46% and 93% in the only-CABG candidates and both CABG and PCI candidates, retrospectively, defined by previous ACC/AHA guideline. Although the discordance between real practice in catheterization laboratory and guideline would be adjusted by recently updated guideline. The revascularization strategy for patients with 3-VD/LMD in real practice have been getting toward more PCI and less CABG surgery. In this study, we will identify the rate of CABG candidates who were treated with PCI or medical treatment instead of CABG surgery in different from current guideline. We are also going to compare two treatment strategies CABG surgery vs. PCI with 2nd generation DES regarding clinical outcomes.

DOC Utility: Screening of Depression, Obstructive Sleep Apnea and Cognitive Impairment

StrokeTransient Ischemic Attack3 more

The primary objective of this study is to determine whether baseline DOC screening can add to clinical and demographic data to predict the occurrence of a composite negative outcome (any of: recurrent stroke, myocardial infarction, death, or admission to a long-term care (LTC) / complex continuing care (CCC) facility) within one year of screening, in stroke prevention clinic patients.

Acute Coronary SyndromeMyocardial Infarction4 more

The EMERALD trial is a multinational, multicenter study. The patients presented with AMI/definite evidence of plaque rupture and had underwent coronary CT angiography from 1 month to 2 year prior to the event will be retrospectively searched.
