At the time of enrollment, information on demographic factors, clinical characteristics, and medical history was gathered. This information included age, gender, body mass index, history of atrial fibrillation (previous atrial fibrillation and new-onset atrial fibrillation at stroke), hypertension, diabetes, prior TIA or stroke, statin use, current smoking (any usage of cigarette per day in the past 30 days) and drinking (drinking more than 100ml (alcohol content>50%) per day on average and drinking for more than 1 year; abstaining from drinking for more than 1 year is not).With the consent of potentially eligible patients, venous blood was extracted from patients at admission and immediately sent for examination. Laboratory tests included; white blood cell count, red blood cell count, hemoglobin, blood platelet count, neutrophil count, red cell distribution width, alanine aminotransferase, aspartate transaminase, free thyroxine, free triiodothyronine, thyroid-stimulating hormone, glucose, glycated hemoglobin A1c, blood urea nitrogen, creatinine, uric acid, total cholesterol, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, international normalized ratio, prothrombin time, activated partial thromboplastin time, D2-dimer, fibrinogen, troponin and C-reactive protein.Ultrasonic cardiograph findings included left atrium diameter, left ventricular end-diastolic diameter, and left ventricular ejection fraction. Trial of Org 10172 in acute stroke treatment (TOAST) classification was divided into large-artery atherosclerosis (LAA), cardioembolic (CE), and others. LAA was defined as >50% stenosis of the vessel lumen in the extracranial or intracranial segment of the internal carotid artery, M1/M2 segment of the middle cerebral artery, or anterior cerebral artery [
