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: sulfa (sulfonamides) attending: chief complaint: cad major surgical or invasive procedure: opcabx3(lima->lad, svg->diag, ramus) history of present illness: this 69 year old man has a history of paroxysmal atrial fibrillation and sick sinus syndrome s/p pacemaker. the patient reports that intermittently over the years, he has noticed a feeling of throat, jaw and chest discomfort associated with his af. this typically occurs when he first goes into the rhythm, lasting five to twenty minutes at a time before resolving spontaneously. he also notices a decrease in activity tolerance and mild lightheadedness when standing up. along with this, the patient has noticed decreased stamina and fatigue that is present all the time, even when he is not in af. he has not noticed chest discomfort or exertional shortness of breath when he is in normal sinus rhythm. because of these symptoms, his physician recommended testing as noted below. ct angiogram revealed possible tight lad disease and he is now referred for cardiac catheterization to further evaluate. past medical history: pmh: paroxysmal atrial fibrillation lbbb sick sinus syndrome s/p pacemaker three to four years ago at probable cad tonsillectomy arthritis sleep apnea (cpap) bph recent diagnosis of prostatitis (seen by urology one week ago and prescribed cipro. patient has not yet started taking this. he denies significant symptoms except for difficulty with urination) social history: social history: patient is married with three children. he is retired. he previously worked in the computer business. his daughter will accompany him to the hospital. she can be reached by cell phone at . family history: fh: both brothers with mi??????s. one brother had an mi in his 50??????s, another in his 60??????s. physical exam: a/o nad grossly intact supple farom neg lymphandopathy cta rrr abd -

ejection fraction now 50-55%. right ventricular systolic function is normal. no other changes compared to pre-grafting study. brief hospital course: pt admiited underwent a cabg x 3 / no complications intra-op extubtes pod # 0 transfered to the the regular floor pod 1 pod # 2 chest tubes removed / repaet x-ray mo pnuemo identified pod # 3 pw removed without sequele pt consult / pt cleared for home with vna pt stable for dc pod # 4 medications on admission: : atenolol 150", dig 0.375', lipitor 20', kcl 10', slo mag 64', flomax 0.4', coum 7.5 mg alt w/ 10 mg discharge medications: 1. atenolol 150", dig 0.375', lipitor 20', kcl 10', slo mag 64', flomax 0.4', coum 7.5 mg alt w/ 10 mg 2. metoprolol tartrate 25 mg tablet sig: 0.5 tablet po bid (2 times a day). disp:*30 tablet(s)* refills:*2* 3. digoxin 125 mcg tablet sig: one (1) tablet po daily (daily). 4. coumadin 7.5 mg tablet sig: one (1) tablet po once a day: inr goal is 2.5 -
