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: heparin agents attending: chief complaint: bl renal masses major surgical or invasive procedure: right partial nephrectomy . history of present illness: 50yo m h/o cad, dilated cardiomyopathy, chf, avr s/p mechanical heart valve, presented to c/o l flank pain x1d. abdominal ct showed bilateral renal masses: left kidney mass 7 cm, exocytic, lower pole and right kidney mass 2.6 cm, w/ infarcted tissue in upper mid left kidney. a renal ultrasound showed a solid 2.6 cm mass on right, and a complex cystic 7 cm mass on the left. an urinalysis showed microscopic hematuria. pt underwent a core biopsy of left renal mass x2. his pain was controlled with a morphine pca and then dilaudid iv and his anticoagulation was switched from coumadin to heparin in the context of his renal biopsy. he is now transferred to for continuation of care. past medical history: cad s/p mi dilated cardiomyopathy c chf (ef 25%) and global hypokinesis aicd (prophylactic for ef, no h/o arrythmias) avr s/p mechanical heart valve 00' osa social history: tob: 1 ppd x 35y until quit 3m ago. married, lives with wife, 1 son. etoh, no drugs. retired employee. family history: father had kidney cancer and prostate cancer. mother had breast cancer. physical exam: gen: lying in bed, nad. wd, wn. heent: ncat, eomi, perrl. no cervical, occipital, clavicular, axillary, or inguinal lad. cv: rrr 3/6 sem at rusb, mechanical click pulmo: ctab abd: obese, soft, nt, nd, no cva tenderness. no palpable masses ext: warm, no c/c/e, 2+ dp/pt. gu: phallus nl. pertinent results: 04:30am blood hct-28.4* 04:31am blood pt-15.2* inr(pt)-1.5 04:31am blood creat-1.1 k-4.2 06:20am blood hbsag-negative hbsab-negative hav ab-positive 06:00am blood igm hav-negative 06:20am blood hcv ab-negative 01:00pm blood heparin dependent antibodies- 10:57pm urine color-straw appear-clear sp -1.030 10:57pm urine blood-lg nitrite-neg protein-neg glucose-neg ketone-neg bilirub-neg urobiln-neg ph-6.0 leuks-neg 10:57pm urine rbc-0 wbc-0 bacteri-none yeast-none epi-0 06:25am blood wbc-8.9 rbc-4.19*# hgb-12.8*# hct-37.1* mcv-89 mch-30.5 mchc-34.5 rdw-13.0 plt ct-96*# 06:25am blood plt ct-96*# 06:25am blood pt-12.9 ptt-52.2* inr(pt)-1.1 06:25am blood glucose-114* urean-16 creat-0.9 na-135 k-3.9 cl-98 hco3-29 angap-12 06:25am blood alt-109* ast-82* ld(ldh)-604* alkphos-81 totbili-0.4 06:25am blood albumin-3.3* calcium-8.8 phos-3.8 mg-2.0 brief hospital course: 50yo m admitted initially to the medicine service for work-up of his newly-dx'd bl renal masses, concerning for malignancy. his platelet count dropped during the time of his transfer, presumably from hit although the one assay performed here was negative. for this reason his anticoagulation was switched to argatroban and carefully titrated to effectively anticoagulate for his mechanical valve; his platelet count normalized. he remained as an inpatient during this complicated work-up period. the pathology report from revealed renal cell carcinoma. a metastatic work-up with head ct, chest ct, abd-pelvic ct, and bone scan was negative except for an adrenal mass whose density was not consistent with benign adenoma. (mri could not be performed due to his aicd). dr. from urology planned a two-stage resection; first a right-partial and then a left-total. cardiac clearance was obtained with a combination of studies from and ; an echo here showed ef 20-30% and he was maintained on beta-blocker. he did develop lue swelling but u/s and ct were negative for dvt. he was maintained on therapeutic argatroban and transitioned successfully to coumadin. ep-cardiology was contact regarding deactivating his aicd. he underwent a bowel prep on the day prior to surgery. a right partial nephrectomy was performed on while on coumadin. see operative report for details. he was placed in the icu post-operatively for close hemodynamic monitoring in light of his complicated cardiac history; he remained intubated with a swan-ganz catheter, chest tube, jp drain, ng tube, and foley catheter. he was extubated without complication on pod 1. on pod 2 the chest tube was removed, cxr showed minimal ptx. the ng tube was removed on pod 3. he was transfused 1 unit prbcs for anemia (hct 27). he remained in the icu for observation related to mobilizing fluid and concern for volume overload given his compromised cardiac output. it was noted that he developed a contact dermatitis, presumably from the tape during surgical positioning; this resolved after several days with topical cream for comfort. he remained stable and was transferred to the regular floor on pod 4 after the swan-ganz was changed over a wire to a triple-lumen catheter. at this time he was passing regular flatus and given a regular (cardiac) diet. his pain control was transitioned to po dilaudid. his hct remained low and he received a 2nd unit of prbcs. the jp drain was removed on pod 5. his inr was closely checked throughout his post-operative course with dosage decreased during immediate post-op period (inr 2.8-3.2); it rose to 3.8 and 3.9 with dosage decreased. after beginning po intake, the inr dropped significantly to 3.4 then 2.1 over 12 hours and then 1.5. his dose meanwhile had been increased to 7.5 qhs. he was resumed on his usual home medications. the foley was removed on pod 6 and the triple-lumen catheter on pod 7. at the time of discharge he was urinating independently, tolerating po diet and pain moderately controlled on po meds. medications on admission: lasix 40 mg po qd toprol xl 50 mg po qd mavik 4 mg po qd lipitor 40 mg po qd colace 100 mg po bid dilaudid 2-4 mg iv q4h heparin 1100 units/hr discharge medications: 1. acetaminophen 325 mg tablet sig: 1-2 tablets po q4-6h (every 4 to 6 hours) as needed. tablet(s) 2. hydromorphone hcl 2 mg tablet sig: 1-2 tablets po q4h (every 4 hours) as needed. disp:*30 tablet(s)* refills:*0* 3. furosemide 40 mg tablet sig: one (1) tablet po daily (daily). 4. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day): while taking dilaudid to prevent constipation. disp:*30 capsule(s)* refills:*1* 5. pantoprazole sodium 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po q24h (every 24 hours). 6. metoprolol succinate 50 mg tablet sustained release 24hr sig: one (1) tablet sustained release 24hr po daily (daily). 7. trandolapril 4 mg tablet sig: one (1) tablet po daily (daily). 8. atorvastatin calcium 40 mg tablet sig: one (1) tablet po daily (daily). 9. warfarin sodium 7.5 mg tablet sig: one (1) tablet po hs (at bedtime) for 1 doses. disp:*30 tablet(s)* refills:*0* discharge disposition: home discharge diagnosis: renal cell cancer heparin-induced thrombocytopenia lue cellulitis dilated cardiomyopathy avr, mechanical valve contact dermatitis discharge condition: stable. discharge instructions: see "nephrectomy" instruction sheet. no baths or soaks or swimming. shower, pat wound dry. do not drive or drink alcohol while taking dilaudid. md if develop fever, or if incision develops redness, swelling, drains pus. heart-healthy diet. followup instructions: follow-up with dr. as previously arranged. call for time and date for staple removal and post-op check, and to discuss/schedule the l nephrectomy. follow-up with primary care physician 2 days to discuss inr and coumadin dosing. have inr checked twice daily until coumadin dose is settled with your pcp. procedure: diagnostic ultrasound of heart pulmonary artery wedge monitoring transfusion of packed cells partial nephrectomy artificial pacemaker rate check diagnoses: abnormal coagulation profile coronary atherosclerosis of native coronary artery congestive heart failure, unspecified malignant neoplasm of kidney, except pelvis systolic heart failure, unspecified other specified forms of chronic ischemic heart disease heart valve replaced by other means other specified procedures as the cause of abnormal reaction of patient, or of later complication, without mention of misadventure at time of procedure unspecified sleep apnea cellulitis and abscess of upper arm and forearm automatic implantable cardiac defibrillator in situ anticoagulants causing adverse effects in therapeutic use
