Final answer:
The first-line treatment for hypertension and renal artery stenosis includes lifestyle changes and medications, with potential surgery if other treatments are inadequate.
Step-by-step explanation:
The first line treatment for hypertension (HTN) and renal artery stenosis involves lifestyle changes and medication. Lifestyle modifications may include weight loss, smoking cessation, regular exercise, and a diet low in sodium and saturated fats. Medications that can be prescribed as first-line treatment for HTN include thiazide-diuretics, calcium channel blockers, ACE inhibitors, and angiotensin receptor blockers (ARBs). Antihypertensive medications should be implemented carefully following a stepped care approach to maintain blood pressure at target levels.
Surgery may be indicated in cases where medications and lifestyle changes are not sufficient to manage the condition or when there is significant obstruction leading to complications. In the context of HTN and renal artery stenosis, surgery can include procedures like angioplasty with stent placement or bypass surgery. The decision to proceed with surgery is typically based on the severity of the stenosis, the presence of resistant hypertension, and the patient's overall health status.
