presented after two significant episodes of hemoptysis and was initially admitted to the medical icu. he received a total of 6 units of prbc during his icu stay and his hct stabilized ~28. he was kept on 8mg/hr pantoprazole drip, then transferred to 40 mg iv bid. his extensive home blood pressure medications including metolazone, metoprolol, torsemide, warfarin, aspirin, and ramipril were held. he was given erythromycin and an emergent egd was performed in the icu which showed erosive gastritis and duodenitis but no active bleeding. he had no further episodes of hematemesis or hemoptysis, with stable vital signs, and so was transferred to the medical floor. there, his hct remained stable and he did not require any more transfusions. he was found to be positive for h. pylori and discharged with a 14 day dose of triple therapy with amoxicillin, clarithromycin, and omeprazole (the last of which he will continue). . # pulmonary hypertension: his medications ambrisentan and sildenafil were initially held while his active gib was managed. he was restarted on sidenafil at his home dose upon transfer to the floor. patient has a chronic 3.5 l home oxygen at baseline but did not require more than 2l oxygen during this hospitalization with oxygen saturation >95%. on discharge, ambrisentan was discontinued after extensive discussion between his outpatient cardiologist, primary care physician, inpatient geriatrics attending. . # hypertension/cor pulmonale: his medications including including metolazone, metoprolol, torsemide, and ramipril were initially held in the context of his gib. his blood pressure remained stable, ranging from 90-110/65-75, with hr ranging 80-90s. this raised the question of whether patient needs his extensive medication regimen at baseline. after extensive discussion with his outpatient cardiologist, primary care physician, inpatient geriatrics attending, the decision was made to discharge him without his hypertensive medications. his primary care physician agreed to manage his hypertensive medications as an outpatient and followup appointment was made for 3 days after discharge. . # benign prostatic hyperplasia: initially, tamsulosin was held for his acute gib. it was restarted after patient was transferred to the medical floor. in the contect of his lowish blood pressure, the geriatric attending decided, after consultation with patient's primary care physician, stop this medication. . medications on admission: ambrisentan 10 mg daily metolazone 5 mg five days a week metoprolol succinate 100 mg daily torsemide 60mg once daily

condition: mental status: clear and coherent. level of consciousness: alert and interactive. activity status: ambulatory - independent. discharge instructions: dear mr. , you were admitted to the hospital because you coughed up a large amount of blood on two different occasions. you were initially admitted to the medical intensive care unit, where they transfused you with 4 units of red blood cells. you had two esophagogastroduodenoscopy (egd) which showed that you had erosive gastritis and duodenititis, which was the most likely source of your bleeding. we held your blood pressure lowering medications as well as blood thinners given that you had recently lost a lot of blood. your primary care physician and outpatient cardiologist will work with you on restarting these medications. after one day in the intensive care unit, your blood cell count stablized and you were transferred to the regular medicine floor. there, we continued to monitor your blood count which remained stable and you did not require any further blood transfusions. your blood pressure which is normally on the low side remained that way throughout the hospitalization. we did a blood test which showed that you have a chronic infeciton in the stomach by a bacteria called helicobacter pylori. you will be discharged with medication to treat that. the following changes were made to your medications: * these medications were stopped* 1. ambrisentan 10 mg daily: this was stopped 2. metolazone 5 mg five days a week: this was stopped 3. metoprolol succinate 100 mg daily: this was stopped
