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 of present illness: the patient is a 56 year old man with morbid obesity and multiple comorbidities from his obesity. these comorbidities include sleep apnea, osteoarthritis, lymphedema, congestive heart failure, and ventral hernia. the patient weighs 500 pounds and a bmi of 60. he has been on multiple weight loss regimens in the past without any significant long term success. the patient presents for elective gastric bypass surgery. physical examination: in general, the patient is in no acute distress, morbidly obese. vital signs are stable, afebrile. chest is clear. cardiovascular is regular rate and rhythm without murmurs, rubs or gallops. the abdomen is obese, soft, nontender, nondistended. extremities - venous stasis disease without active ulcers, 1+ pitting edema bilaterally in the lower extremities. neurologically, the patient is alert and oriented times three. no gross deficits. past medical history: 1. atrial fibrillation, status post pacemaker. 2. congestive heart failure. 3. sleep apnea. 4. osteoarthritis. 5. lymphedema in pannus and right groin. 6. ventral hernia repair . medications on admission: 1. lasix 80 mg once daily. 2. zoloft 50 mg once daily. 3. toprol 50 mg once daily. 4. coumadin 10 mg once daily. 5. lovenox 45 mg once daily. 6. cozaar 50 mg once daily. 7. tylenol p.r.n. hospital course: the patient was admitted for elective open gastric bypass surgery. the surgery proceeded without complication. the patient was left intubated and sent to the intensive care unit for closer monitoring and ventilatory support. this is due to his cardiac status. the patient did have a known ejection fraction of 30 to 35% documented on echocardiogram. postoperatively the patient did well and was extubated on postoperative day number one without complication. the patient was also advanced to stage i diet. on postoperative day two, the patient was transferred to the floor and advanced to stage ii diet. the patient did complain of a little bit of chest pressure. an electrocardiogram was obtained which was unchanged from his preoperative electrocardiogram. the patient described his chest pressure as feeling as if he had eaten too much. decision was made not to cycle cardiac enzymes. the patient did well otherwise. on postoperative day three, the patient was advanced to a stage iii diet. the patient was subsequently discharged to home tolerating a stage iii diet. condition on discharge: good. disposition: to home. diet: stage iii diet per gastric bypass protocol. medications on discharge: 1. roxicet elixir one to two teaspoons q4hours p.r.n. 2. actigall 300 mg p.o. twice a day. 3. zantac liquid 150 mg p.o. twice a day. 4. vitamin b12 1000 mcg once daily. 5. lasix 80 mg once daily. 6. zoloft 50 mg once daily. 7. toprol 50 mg once daily. 8. coumadin 10 mg once daily. 9. lovenox 45 mg once daily. 10. cozaar 50 mg once daily. 11. tylenol p.r.n. follow-up: the patient is to follow-up with the surgical clinic in two weeks time. he is to maintained a stage iii diet until that time. , m.d. dictated by: medquist36 procedure: high gastric bypass diagnoses: congestive heart failure, unspecified atrial fibrillation unspecified sleep apnea morbid obesity long-term (current) use of anticoagulants osteoarthrosis, unspecified whether generalized or localized, site unspecified 

Answer: The patient is high likely exposed to
