Background and Purpose: The etiology of Ischemic Stroke affects its

prognosis, outcomes and managements. The objective of this study is to

determine the risk factor profiles, severities, complications, current treatment

strategies and prognostic differences in the acute ischemic stroke subtypes.

Methods: We prospectively investigated of 140 consecutive patients with

acute ischemic stroke [37.9% women, median age 61.5 (53-72) years] since

June to August 2013. All of the patients was categorized to the one of five of

major ischemic stroke subtypes by TOAST (Trial of Org 10172 in Acute Stroke

Treatment) based on the MRI Imaging [ Small vessel Atherosclerosis (SAO),

Large vessel Atherosclerosis (LAA), Cardiac Embolism (CE), Other Determined

etiology (OD), other Undetermined etiology (UND) ].

Results: This study found that the age, severity, complications, treatment

strategies, costs and outcomes were significantly difference in each subtypes of

stroke (p< 0.001). The distribution of subtypes by more often was SAO, LAA,

CE, OD, UND (45, 34.3, 12.9, 4.3, 3.6 %) respectively. The CE subtype had the

oldest median age [68.5(51.2-71.5) yrs] and the OD subtype had the youngest

median age [39(31-66) yrs]. The obesity (33.3%), complication [brain edema
