Brief Summary:
Contrast-enhanced ultrasound(CEUS) of carotid artery plaque is a novel method that enabled direct visualization of neovessels in the vulnerable plaque. Plaque enhancement with CEUS showed correlation with the histologic density of neovessels within the carotid plaque and the previous cardiovascular events. Vulnerable plaques with a high risk of thromboembolic complications and rapid progression is associated with acute ischemic stroke. The prognostic value of vulnerable carotid artery plaque depicted with CEUS has not been fully investigated. The purpose of this study is to define prognostic value of plaque enhancement on carotid CEUS in acute stroke patients. Research question is; in acute ischemic stroke patients with ipsilateral carotid plaque as probable etiology of stroke, is the presence of carotid plaque enhancement on CEUS independent predictor of future stroke.

Study Type : Observational [Patient Registry]
Estimated Enrollment : 667 participants
Observational Model: Cohort
Time Perspective: Prospective
Target Follow-Up Duration: 12 Months
Official Title: Prognostic Value of Carotid Contrast-Enhanced Ultrasound in Acute Ischemic Stroke Patients for Cerebrovascular and Cardiovascular Event
Actual Study Start Date : August 9, 2017
Estimated Primary Completion Date : September 30, 2020
Estimated Study Completion Date : September 30, 2020

Primary Outcome Measures :
  1. Composite of recurrent stroke, vascular death and myocardial infarction [ Time Frame: 12 months ]
    (1) recurrent stroke: newly appeared DWI positive lesion on brain MRI with corresponding neurologic symptom (2) vascular death: sudden death, death due to stroke, myocardial infarction, heart failure, arrhythmia, pulmonary embolism, systemic bleeding, or ischemia of organ. (3) myocardial infarction: at least two of the followings: ① a history of typical angina pain. ② Elevation of Troponin, ③ Newly developed ST change or Q waves or LBBB on ECG (outcomes will be measured by chart review or physician diagnosis or telephone interview)

Secondary Outcome Measures :
  1. Ipsilateral stroke [ Time Frame: 12 months ]
    Recurrent stroke of ipsilateral side (recurrent stroke at same side of previous infarction)

  2. All-cause mortality [ Time Frame: 12 months ]
    All of the deaths, regardless of the cause

  3. Carotid intervention [ Time Frame: 12 months ]
    Ipsilateral carotid endarterectomy or carotid artery stent insertion which was not planned when discharge.
