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: past medical history: history revealed hypertension and congestive heart failure. physical examination: on physical examination, the patient neurologically is awake, alert, oriented time three with no pronator drift, no facial droop. motor strength was in all muscle groups with the exception of the right deltoid, which was 4+/5. the ct showed a 2-cm subdural hematoma over the right temporal parietal region with compression of the right ventricle and some mass effect. he was admitted to the surgical intensive care unit for close monitoring. on , the patient went to the operating room for drainage of the right subdural hematoma, without intraoperative complications. postoperatively, the patient was monitored in the surgical intensive care unit. on the ekg showed 1-mm to 2-mm s-t depression in the v1 through v6 leads with some complaints of nausea and chest pain with a blood pressure of 170. he was given one sublingual nitroglycerin with gradual decreased in his heart rate down to the 30s and his systolic blood pressure down to the 60s. he required five minutes of iv neo-synephrine in african-american female 250 cc bolus saline. his blood pressure recovered along with his heart rate. the department of cardiology recommendations were to avoid preload reduction, continue beta blocker for blood pressure and heart rate control and when the patient recovers from the subdural hematoma repeat echocardiogram and cardiac catheterization for further assessment of his aortic stenosis. the patient's subdural drain was discontinued on . the patient was awake, alert, and oriented times three. he was following commands with no drift. face was symmetrical. the patient was transferred to the regular floor with the blood pressure under better control off nipride. the patient was seen by the physical therapy and occupational therapy. he was found to require rehabilitation. medications on discharge: 1. colace 100 mg p.o.b.i.d. 2. zantac 150 mg p.o.b.i.d. 3. metoprolol 25 mg p.o.q.d. 4. cozaar 50 mg p.o.q.d. 5. isosorbide mn 60 mg p.o.q.d. 6. tylenol 650 p.o.q.4h.p.r.n. 7. nitropaste ?????? inch q.6h. hold for blood pressure less than 110. the patient was in stable condition at the time of transfer to rehabilitation. the patient will followup with dr. in two to three weeks time. the patient was neurologically stable at the time of discharge with stable vital sign and afebrile. the patient will need to followup with the department of cardiology after recovery from subdural hematoma or evacuation, most likely, after he sees dr. in followup. , md dictated by: medquist36 procedure: incision of cerebral meninges diagnoses: unspecified essential hypertension hyposmolality and/or hyponatremia coronary atherosclerosis of unspecified type of vessel, native or graft unspecified fall other and unspecified angina pectoris subdural hemorrhage following injury without mention of open intracranial wound, unspecified state of consciousness 

Answer: The patient is high likely exposed to
