Intervention with stent placement in symptomatic/high-risk ARAS patients presenting with resistant hypertension, acute kidney injury, or flash pulmonary edema associated with significant renal artery stenosis can result in clinical improvement and a reduction in antihypertensive medication requirements, even within a short follow-up period of 4 weeks. Given the retrospective design, lack of a control group, and short follow-up, these findings should be interpreted as association rather than causation and cannot address long-term outcomes (e.g., restenosis, durable renal preservation, or cardiovascular events).
Cevher et al. (Fri,) studied this question.
