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: allergies: no allergies/adrs on file attending: chief complaint: s/p cardiac arrest major surgical or invasive procedure: right internal jugular central venous catheterization left femoral arterial catheterization history of present illness: 38 yo m with history of hcv and heroin abuse, who collapsed after snorting heroin. his friends, who were also using drugs, hit him in an attempt to awaken him. they called ems, who reportedly arrived after 5 minutes. he was reportedly initially not in a shockable rhythm and received 20 minutes of cpr. during cpr, he received epinephrine 4 mg, narcan 4 mg, and 40 units of vasopression. he was intubated by ems. . he was initially brought to hospital, where he was found to be in vfib and regained spontaneous circulation with 1 shock. he was transferred to for further management. urine tox was positive for benzos, opioids, ethanol, marijuana. . in the ed at , initial vital signs were t 32c hr 69 bp 127/66 rr 20 sat 99%. he had no gag reflex, no reponse to painful stimuli, pupils fixed 6 mm. gcs 3. he did overbreath the vent. he was taken for ct, which showed extensive cerebral edema with herniation, consistent with global hypoxic injury. after ct, he became hypertensive to 230s/140s, and there was concern for further herniation, but this was later felt to be secondary to asynchrony. the patient was given vecuronium and propofol and started on a propofol gtt, with normalization of his blood pressure. the patient was also given mannitol 25 gm iv x 2. a right ij cvl was placed in the ed. a left femoral a-line was placed due to difficulty placing a radial a-line. the patient was noted to have copious urine and stool output. . neurosurgery was consulted in the ed, and communicated that due to the patient's extemely poor prognosis, there was no indication for intracranial pressure monitoring. . vitals at the time of transfer to were hr 105 sbp 140s. on arrival to the micu, the patient was unresponsive and unable to give a history. . ros: unobtainable past medical history: past medical history ( hospital ed records): hepatitis c h/o shoulder separation adjustment reaction with anxiety and depression . past surgical history ( hospital ed records) hernia repair laproscopic cholecystectomy social history: notable for drug use. parents are deceased. no children. never married. has a half-brother , who lives in , an a half-sister . family history: non-contributory physical exam: vs: hr 111 bp 124/78 sat 95% gen: unresponsive. intubated. heent: pupils 6 mm and fixed. bruising around eye. neck: no jvd. right ij in place. resp: cta b/l cv: rr, s1 and s2 wnl, no m/r/g abd: nd, +b/s, soft, nt, no masses or hepatosplenomegaly, copious stool output ext: no c/c/e skin: no rashes/no jaundice/no splinters neuro: unresponsive to voice, sternal rub, or painful stimuli. no spontaneous movement. pupils 6 mm and non-reactive. corneal reflexes absent. no oculocephalic reflex. face symmetric. pertinent results: 05:00pm blood wbc-23.0* rbc-4.37* hgb-13.8* hct-42.0 mcv-96 mch-31.5 mchc-32.8 rdw-12.9 plt ct-186 07:17pm blood pt-14.3* ptt-45.4* inr(pt)-1.2* 12:44am blood glucose-43* urean-25* creat-1.5* na-142 k-4.2 cl-123* hco3-11* angap-12 09:51pm blood glucose-96 urean-22* creat-1.3* na-139 k-6.4* cl-116* hco3-13* angap-16 05:00pm blood alt-379* ast-453* 05:00pm blood lipase-85* 05:00pm blood ctropnt-<0.01 05:00pm blood ck-mb-5 05:00pm blood calcium-7.1* phos-8.9* mg-2.5 05:00pm blood asa-neg ethanol-neg acetmnp-neg bnzodzp-neg barbitr-neg tricycl-neg . micro: 5:00 pm blood culture (resulted reported as positive after patient's death) blood culture, routine (preliminary): gram positive coccus(cocci). in pairs and chains. anaerobic bottle gram stain (final ): gram positive cocci in pairs and chains. . imaging: . ct head w/o contrast : 1. global cerebral edema and effacement of sulci consistent with global anoxic injury. 2. early downward transtentorial herniation secondary to cerebral edema. findings discussed with the emergency room and the icu team. . cxr (portable ap) : limited study as above. question possible infiltrate at the right lung base versus atelectasis. endotracheal tube and nasogastric tube both in satisfactory position. brief hospital course: 38 yo m admitted to micu s/p cardiac arrest in setting of drug abuse, with head ct indicating anoxic brain injury and cerebral edema, with signs of early hearniation. . # anoxic brain injury: head ct showed anoxic brain injury with cerebral edema and early herniation. neurosurgery was consulted in the emergency department and stated that the prognosis was very poor, with recovery highly unlikely. for this reason, neurosurgery recommended against any neurosurgical intervention. this prognosis was discussed with the patient's half brother and half sister by the micu team. . # s/p cardiac arrest: the patient was started on an arctic sun cooling protocol. however, after a family meeting in the micu, during which the patient's very poor neurologic prognosis was explained, the family decided that it would be most consistent with goals of care for the patient to be made comfort measures only. at this point, the cooling protocol was stopped. . # hypotension: the patient developed hypotension which was treated with phenylephrine and iv fluids. . # hyperkalemia: the patient had hyperkalemia to 6.4, which was treated with calcium, insulin, and dextrose, with improvement in the patient's potassium to 4.2. . # heroin overdose: narcan given prior to admission. . # goals of care: the micu team met with the patient's half brother , as well as wife. the micu team also spoke with the paient's half sister via telephone. and explained that the patient's parents were deceased and that the patient had no children, was never married, had no other siblings or half siblings, and had no other relatives. they also explained that the patient had never selected a healthcare proxy. therefore, and were determined to be the patient's next of . during extensive conversations, during which the patient's prognosis was discussed, and explained that the patient would not want to be kept alive on life support unless there were a reasonably good chance that he would have the ability to function and live independently. the micu team explained that given the patient's anoxic injury and cerebral edema, such a recovery was extremely unlikely. and decided that it would be most consistent with the patient's wishes to be made comfort measures only, without any further life-sustaining therapy. the patient's vasopressors were stopped, and he was subsequently extubated. he died peacefully and was pronounced dead at 3:04 a.m. on . the medical examiner was , and given the circumstances of the patient's cardiac arrest, the case was accepted for review. medications on admission: unknown discharge medications: none discharge disposition: expired discharge diagnosis: primary: 1. heroin overdose 2. cardiac arrest 3. hyperkalemia discharge condition: expired discharge instructions: n/a followup instructions: n/a procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified other electric countershock of heart arterial catheterization diagnoses: hyperpotassemia unspecified viral hepatitis c without hepatic coma hypotension, unspecified cardiac arrest anoxic brain damage cerebral edema accidental poisoning by heroin opioid abuse, unspecified poisoning by heroin adjustment disorder with mixed anxiety and depressed mood
