, 80 percent first obtuse marginal, and a 50 percent proximal right coronary artery lesion. he was referred for coronary artery bypass grafting to dr. . he also reports in addition to his chest pain and some edema, he denied shortness of breath, nausea, vomiting, diaphoresis, or palpitations at the time of his angina. past medical history: right coronary artery stent in and hypertension. past surgical history: none. allergies: no known drug allergies. medications on admission: toprol 100 mg p.o. in the morning and 50 mg p.o. in the evening, imdur 90 mg p.o. once daily, aspirin 325 mg p.o.

rate was 15, the blood pressure was 153/81, and saturating 96 percent on room air. he was lying flat in bed in no apparent distress when he was seen after his cardiac catheterization. he was alert and oriented times three and appropriate. his lungs were clear to auscultation bilaterally. heart revealed a regular rate and rhythm with s1 and s2 tones. no murmurs, rubs, or gallops. the abdomen was obese, soft, nontender, and nondistended with positive bowel sounds. his extremities were warm and well perfused with dry skin, but no edema or varicosities. he had 2 plus bilateral radial pulses, 2 plus right dorsalis pedis and posterior tibial pulses, and 1 plus left dorsalis pedis and posterior tibial pulses. preoperative laboratory data: white blood cell count was 5.9, the hematocrit was 36.2, and the platelet count was 150,000. sodium was 137, potassium was 3.8, chloride was 106, bicarbonate was 23, blood urea nitrogen was 17, creatinine was 0.7, with a blood sugar of 134. pt was 14, ptt was 32.3, and inr was 1.2. alt was 21, ast was 13, alkaline phosphatase was 61, amylase was 74, total bilirubin was 0.5, and albumin was 3.8. suof hospital course: the patient was referred to dr. . additional preoperative work was done and showed a urinalysis was negative. electrocardiogram showed a sinus rhythm at 64 with av conduction delay. the patient was to be sent home and return on for surgery. the patient was admitted on but was admitted secondary to another emergency cardiac operation that delayed dr. surgery. he was also seen by dr. of cardiothoracic surgery and was rescheduled for the following morning and was admitted to the hospital. on the patient underwent coronary artery bypass grafting times four with a lima to the lad, a vein graft to the rca, a vein graft to the diagonal, and a vein graft to the by dr. and transferred to the cardiothoracic intensive care unit in stable condition on a titrated propofol drip and a nitroglycerin drip at 0.2 mcg/kg/min. on postoperative day one, the patient had a blood pressure of 122/54 and a heart rate of 75, in a sinus rhythm. he had been extubated and was saturating 97 percent on nasal cannula. postoperative laboratories as follows. white blood cell count was 8.9, the hematocrit was 32, and the platelet count was 120. potassium was 4.3, bun was 11, creatinine was 0.8, with a blood sugar of 145. the patient remained on a nitroglycerin drip at 0.2 mcg/kg/min. started lasix and his beta blocker. the chest tubes were removed, and the examination was unremarkable. the lungs were clear. the abdomen was soft, nontender, and nondistended. his incisions were clean, dry, and intact. he was transferred out to the floor. on the floor, he had a full evaluation by a physical therapist to begin his ambulation with the nurses and physical therapist. on postoperative day two, the patient had one episode of atrial fibrillation with a ventricular response of greater than 120. he was given 5 mg of intravenous lopressor which brought him down to the 90s. his blood pressure remained stable at 111/69. he was saturating 97 percent on room air. he remained otherwise unremarkable. he was making good progress. his chest tubes had been pulled, and his pacing wires were pulled that afternoon without incident. the patient had minimal incisional pain. on postoperative day three, he again went into atrial fibrillation and was bolused with amiodarone and then given an oral dose which converted him to a normal sinus rhythm. he was started on amiodarone 200 mg p.o. once daily. he remained alert and oriented with a nonfocal neurologic examination. his examination was otherwise unremarkable. the incisions were clean, dry, and intact. he continued with his diuresis. he continued to ambulate well on the floor. he was receiving tylenol for pain. he was voiding well. on the patient was discharged to home. he was given some hot packs for a phlebitis that developed in his right hand, and 500 mg of keflex was given prior to his discharge. discharge disposition: he was discharged to home with vna services for home care. condition on discharge: stable. die instructions: 1. the patient was to see dr. in the office approximately four weeks postoperatively for his postoperative surgical visit. 2. the patient was also instructed to follow up with his cardiologist - dr. - in approximately 7 to 10 days post discharge. discharge diagnoses: 1. status post coronary artery bypass grafting times four. 2. status post right coronary artery stent. 3. hypertension. medications on discharge: 1. lasix 20 mg p.o. twice daily (for one week). 2. potassium chloride 20 meq p.o. twice daily (for one week). 3. keflex 50 mg p.o. four times daily (for one week for right hand phlebitis). 4. amiodarone 200 mg
