Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: history: past medical history of afib, on coumadin, and right thalamic hemorrhage; presents with left-sided weakness and mutism. comparison is made with ct perfusion from one day prior. on the diffusion-weighted images, there is no evidence for acute ischemia. there is extensive confluent periventricular and subcortical hyperintensity which likely reflects small vessel ischemic sequela. there are bilateral thalamic lacunes. small vessel ischemic sequela is also seen in the brain stem. there is mucosal thickening in the sphenoid sinus. on the gradient echo images, there are foci of susceptibility dropout in bilateral thalami which may be related to prior microhemorrhages or cavernomas. mra of the circle of demonstrates patency of the major intracranial vessels and their proximal branches. the small aneurysm of the left pca is unchanged from the recent cta examination. additionally, there is suggestion of a 3 mm aneurysm at the left pcom origin. evaluation of the mrv demonstrates patency of the superficial venous system. the deep veins are not visualized, which may be related to technique. impression: no evidence for acute ischemia. extensive small vessel ischemic sequela. aneurysm of the left pca and left posterior communicating artery. (over) 12:53 am mr head w/o contrast; mra brain w/o contrast clip # reason: please perform mri/mra brain admitting diagnosis: altered mental status ______________________________________________________________________________ final report (cont) procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified insertion of endotracheal tube insertion of endotracheal tube enteral infusion of concentrated nutritional substances arterial catheterization diagnoses: subendocardial infarction, initial episode of care urinary tract infection, site not specified congestive heart failure, unspecified unspecified essential hypertension acute and subacute necrosis of liver unspecified septicemia atrial fibrillation subarachnoid hemorrhage paroxysmal ventricular tachycardia pneumonitis due to inhalation of food or vomitus septic shock long-term (current) use of anticoagulants methicillin susceptible pneumonia due to staphylococcus aureus encephalopathy, unspecified acute on chronic systolic heart failure 

Answer: The patient is high likely exposed to
