**1. Introduction**

Stroke is a neurovascular disease with a high incidence throughout the world; according to the global stroke fact sheet 2019 by World Stroke Organization, stroke is the second leading cause of death and the third leading cause of disability. As up to 13.7 million new cases of stroke each year, globally one in four people over age 25 will have a stroke in his or her lifetime. About 5.5 million people die from stroke annually, and 39% of all who die from stroke are under 70 years old [1]. The burden of stroke is due to widely prevalent risk factors such as hypertension, diabetes, smoking, metabolic syndrome, and behavioral factors. Modification risk factors and administration preventive therapy are the keys to decrease stroke burden. Besides of the systemic disease such as hypertension can cause stroke, a number of cardiac diseases and vascular diseases affected intracranial arteries such as non-valvular atrial fibrillation, prosthetic heart valve, dilated cardiomyopathy, atrial appendage thrombus and atrial myxoma, atherosclerosis disease of aortic arch, neck arteries and intracranial arteries, arterial dissection etc. are the common causes of stroke [2–4]. Those conditions are prone to cause an embolic stroke (cardioembolic or artery to artery embolism). Antithrombotic

agents such as antiplatelet drugs and anticoagulants are the drugs that are efficient in the prevention of embolic stroke. Thus, a majority of patients who have high risk factors in the group of stroke experience and inexperience stroke might have a regular anticoagulant administration. Regular monitoring of prothrombin time and International normalized ratio (INR) to predict the bleeding complications. Because ischemic and hemorrhagic strokes have different causes and effects on the body, both require different treatments. The accurate diagnosis types of strokes as ischemic stroke or hemorrhagic stroke is important. Neuroimaging is the investigate procedure to make a correct diagnosis type of stroke and extension of stroke lesion that take part in triage stroke 2patients for further proper management.

Guideline recommendation for stroke prevention (ischemic stroke/TIA) [5]:


Stroke has three major subtypes:

1.Ischemic stroke

## 2.Hemorrhagic stroke
