<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 67-year-old man presents to the physician for a followup examination. He was diagnosed with hypertension 12 years ago. He had a coronary stent placement 2 years ago. His medications include aspirin, atorvastatin, lisinopril, hydrochlorothiazide, and carvedilol. Amlodipine was also added to his medication list 2 months ago to control his blood pressure. He has no history of smoking. He is on a plant-based diet. His blood pressure is 175105 mm Hg, pulse is 65min, and respirations are 14min. His BMI is 24 kgm2. In addition, his serum creatinine was 1.2 mgdL which was tested 3 months ago. The most recent blood work reveals that his serum creatinine has increased to 1.6 mgdL. The Doppler velocity in the right renal artery is 300 cms. The contrast-enhanced CT shows 70 stenosis in the right renal artery. Which of the following is the most appropriate next step in management?? A: Adding losartan, B: Renal artery revascularization, C: Enoxaparin, D: Tissue plasminogen activator, E: Maximizing the dose of antihypertensive medications,  <response>: This is a patient with hypertension and renal artery stenosis. The key findings are:- 67-year-old man with long standing hypertension - History of coronary stent 2 years ago- On multiple antihypertensive medications including lisinopril, hydrochlorothiazide, carvedilol, amlodipine- Blood pressure not well controlled at 175105 mmHg despite medications- Serum creatinine increased from 1.2 to 1.6 mgdL over 3 months - Doppler shows high velocity flow in right renal artery suggestive of stenosis - CT confirms 70 stenosis in right renal artery- No smoking history The elevated blood pressure despite multiple medications and rising creatinine with evidence of renal artery stenosis points to renovascular hypertension. The next step would be to consider revascularization of the stenotic renal artery rather than just adding more medications.Choice A of adding losartan would not address the underlying anatomical problem of renal artery stenosis. Choices C and D of enoxaparin and tPA are not indicated. Choice E of maximizing medications may help control BP temporarily but does not treat the underlying cause.Therefore, choice B of renal artery revascularization is the most appropriate next step in management. This can help improve blood pressure control and potentially stabilize or improve renal function. B: Renal artery revascularization
