Why ACE inhibitors are contraindicated in renal artery stenosis?
HTML-код
- Опубликовано: 9 сен 2024
- Angiotensin-converting enzyme inhibitors (ACEIs) are contraindicated in patients with bilateral renal artery stenosis due to the risk of worsening of renal function due to preferential efferent arteriolar vasodilation in the renal glomerulus due to inhibition of angiotensin II.
Thanks for watching the video, hope it was helpful.
Good video. Straight to the point. God bless
thank you👍🏻
Nice, straightforward
thank you
Thanks it is great presentation in minimum time
thank you
Thank you soooo soon much
you're welcome
Too good
thank you
Thanks ❤
you're welcome
Thankyou
you're welcome
Thanx❤
you're welcome
Bigggggggggg thanx
B/c i was have disterpanse
you're welcome
Can't we use renin inhibitor...
Can we use ARBs? In this case?
better to avoid them also
How we can use this when the patient comes?We don't exactly know the patient have renal arter stenosis or not unless we can do ultrasound so is there any indicators such as kreatin ? We cant give the patient with high kreatin level or low gfr ?can we say that
yes renal function test and electrolytes, to be checked before starting ACE inhibitors. You can read this article for more details...

If patient has unilateral renal stenosis, can we still use acei?
better to avoid
Can you write the reason in the comments please 🙏
Efferent arteriole constriction by renin in renal artery stenosis, creates a pressure gradient between the afferent and efferent arteriole, this pressure gradient maintains the GFR, inspite of low renal blood perfusion due to renal a. stenosis. If ACE inhibitors are given, this compensatory mechanism, that is Renin secretion is blocked, and the efferent arteriole constriction doesn't happen, there will be no pressure gradient between afferent and efferent arteriole, so GFR decreases, leading to renal failure
Not clear to me at all

It's not quite clear
