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: 1. gerd. 2. prostate cancer. 3. hypercholesterolemia. transfer medications: 1. integrelin. 2. plavix. 3. aspirin. 4. docusate. 5. senna. 6. lipitor. 7. morphine. family history: noncontributory. social history: the patient quit smoking in . the patient does not have a history of alcohol use or illicit drug use. hospital course: 1. coronary artery disease: the patient is status post massive anterior wall mi with cardiac catheterization complicated by inability to achieve adequate flow to the proximal lad complicated by cardiogenic shock on intra-aortic balloon pump upon transfer to the cardiac care unit. the patient has been stabilized on intra-aortic balloon pump. the patient had an urgent echocardiogram done which showed ejection fraction of 20% and severe anterior and apical hypokinesis. the patient was maintained on intra-aortic balloon pump for the first two days. there was no evidence of end-organ damage of hyperperfusion. the patient's peak ck was over 7,000 and has been trending down since day number two of ccu admission. we were able to wean the patient off balloon pump on . heparin was started as well as an ace inhibitor. the patient has also been started on a statin, aspirin, and a low-dose beta blocker for his coronary artery disease. the patient has tolerated afterload reduction with an ace inhibitor well and has had no symptoms of chest pain since admission. the patient suffered a drastic decrease in the cardiac function as evidenced by an ejection fraction of 20%. the patient is at risk for development of apical clot post mi as evidenced by apical kinesis. therefore, the patient has been anticoagulated with heparin. the patient is likewise at high risk for sudden cardiac death as evidenced by ejection fraction of 20%. however, in order to properly risk stratify the patient, the patient is to undergo signal-averaged ekg on monday to establish his risk for malignant ventricular arrhythmias. in the meanwhile, we continued optimizing the patient's cardiac function with ace inhibitors, beta blockers. during the stay in the cardiac care unit, the patient developed atrial fibrillation on , several hours after removal of intra-aortic balloon pump. the patient had atrial fibrillation with rapid ventricular response at a rate of 150s to 170s. the patient has remained hemodynamically stable and has been asymptomatic. several doses of lopressor 5 mg iv push were tried with only transient response. subsequently, the patient was started on an amiodarone drip 1 mg per minute, but developed transient hypotension with systolic blood pressures of 70, maintaining his mean arterial pressure of above 55. therefore, intravenous amiodarone was stopped and the patient was started on amiodarone 400 mg p.o. b.i.d. the patient has remained in atrial fibrillation until the patient was started on esmolol drip and has converted to a normal sinus rhythm in two hours after initiation of the esmolol drip. throughout the day afterwards, the patient has remained in normal sinus rhythm and was transferred to the general nursing floor. however a few hours thereafter, the patient developed atrial flutter with 1:2 conduction at a rate of 120 that was found to be nonresponsive to beta blockers. the patient was asymptomatic and maintained good mean arterial pressures but was transferred to the cardiac care unit and was started on an esmolol drip with no response this time. it was decided that most likely the patient went into atrial flutter secondary to amiodarone treatment of atrial fibrillation. the patient's amiodarone was increased to 400 mg p.o. t.i.d. esmolol drip was titrated off and the patient was restarted on coreg 6.25 mg p.o. b.i.d. the patient's ace inhibitor was held in order to prevent hypotension that could be expected with increasing amiodarone. the patient, as before, has remained asymptomatic and stable. it was planned to attempt and achieve rate control with amiodarone and if rate control unable to achieve or if the patient was to become hemodynamically unstable to cardiovert electrically. immediate cardioversion was not done since the patient remained hemodynamically stable and also since awaiting signal-averaged ekg results to show whether the patient would at the same time benefit from an icd implantation. this dictation is to be followed by an addendum. , m.d. dictated by: medquist36 procedure: insertion of non-drug-eluting coronary artery stent(s) coronary arteriography using two catheters injection or infusion of platelet inhibitor insertion of temporary transvenous pacemaker system atrial cardioversion implant of pulsation balloon right heart cardiac catheterization diagnoses: coronary atherosclerosis of native coronary artery congestive heart failure, unspecified acute myocardial infarction of other anterior wall, initial episode of care cardiac complications, not elsewhere classified atrial fibrillation atrial flutter

Answer: The patient is high likely exposed to
