#Creatinine
is least important lab value at
#ICU
. No reason to give fluids, no reason for RRT! Keep
#kidneys
happy with perfusion pressure & avoidance of volume overload, ALWAYS irrespectively of Cr!
That's why I am not so worried at ICU if Cr rises, but urine output remains preserved!
Actually, I don't care about Cr too much at all & do not try to prevent a rise. Instead, I'll try to keep good perfusion & get rid of congestion. This saves nephrons & kidney on the long run!

To all members, please don’t forget to vote for these fantastic people!
Here are my top six priorities....together we can make it
Which upcoming trial are You looking forward to the most? Easy choice for me:
#ADVOR
☑️largest
#diuretic
RCT ever
☑️finally high quality data on
#acetazolamide
in
#heartfailure
☑️real-world streamlined trial in 🇧🇪
Going to be a “wet” summer 😉!
Results of the randomized
#ADVOR
trial are soon coming your way! It's the largest diuretic trial in acute
#heartfailure
ever conducted (N=519) and will test acetazolamide on top of loop diuretics. Recruitment is finished and full database lock is anticipated. Find out more (1/9).
@DanielleTBurton
@sargsyanz
UNa: so easy and helpful! Train your nurses to take spot samples after every diuretic administration as they check BP after changing vasopressor dose.
>100 mmol/L: excellent diuretic response
70-100 mmol/L: acceptable
<70 mmol/L: will not end up with 2L!
Finally, the game changer we were craving for in
#HFpEF
! This makes
#SGLT2i
indicated in almost EVERYBODY (at risk of)
#HeartFailure
! Time to focus upon implementation…
Baseline characteristics paper of
#ADVOR
published which is largest RCT on diuretic therapy in AHF. Compared with other diuretic RCT: more elderly population, ↑congestion - NT-proBNP > 6000, 82% CKD = patient profile observed in clinical practice (1/4)
What are you doing with 4-pillar therapy when BP is low?
Here is my approach:
- MRA: hardly any impact of low-dose spironolactone, just continue
- SGLT2i: usually no problem either, but careful if low output state
- BB: keep, might decrease if electrically stable. STOP if low CO!

#hartfalen
proactief én preventief aan.
@HeartBrussels
Moreover, kidneys are smart organs:
Proximal = leaky➡️keeps distal nephron flow 🟰
Distal = waterproof ➡️homeostasis
Proximal diuretics ➡️more distal flow➡️give kidneys back control on homeostasis (they are far better than cardiologists)
Thus, as the Great Guyton has teached us:
Blood pressure is not the same as
#Perfusion
So we need to employ vasodilators in patients who are very vasoconstricted with low
#CardiacOutput
, typically w low SBP, low
#PulsePressure
& preserved MAP
90/70 mmHg means MAP=77 mmHg!!!
The kidneys in essence have 3 functions:
1. Glomerular function = Clearance
2. Tubular function = Homeostasis
3. Neurohumoral function
GFR mainly reflects 1. So why do we take GFR (or its estimate Cr) as a surrogate for renal function?
Biggest problem in
#ICU
is often homeostasis (volume, electrolytes) rather than clearance (uremia).
Remember, homeostasis is mostly a tubular rather than glomerular function. Even with GFR 15 mL/min, one filters >20 L & 184 g salt per day! More than enough to get rid of those!
Also, more chloride from proximal to the macula densa sensor acts like a break on the neurohumoral system.

The CON party, will undoubtedly point towards failing trials with vasodilators in AHF, but look who they recruited, this is no low output

First some background...
Current

guidelines state (IIb, B): "In patients with AHF and a systolic blood pressure (SBP) >110 mmHg, intravenous vasodilators may be considered as an initial therapy to improve symptoms and reduce congestion."
Only 1 flowchart has them in...

Intriguing paper by Milton Packer

#AHAJournals
Look at GFR determinants (=N x snGFR).
In stable circumstances, GFR mainly reflects the number of functional nephrons.
Starting from 1 million per kidney at birth, one loses 5,000-10,000 per year with aging: age-related GFR decline <1 mL/min/1.73m²/y
If You remember 1 thing from our paper, let it be: "SBP = awful marker of
#afterload
or ventriculo-arterial coupling, making it pretty useless in decision to employ
#vasodilators
"
If anything vasodilators work best in patients with LOW SBP:

@WilsonTangMD
Key messages:
1. Many
#HFrEF
patients do not achieve target HR
2. Poor correlation between beta blocker dose and HR reduction achieved (hyper-responders do better!)
Why is this? Need pressure-volume loops in here:
In preserved CO/SV (steep Ees~contractility), reducing afterload (Ea) has little impact on stroke volume (SV), which is already high. However, marked impact on BP (preload dependency!)
Counting the days until the start of
#ESC2022
? No doubt which topic is on everybody’s mind:

a clear winner!

Welcome aboard
@TimBalthazar
, our first paper together, but I promise You it won't be our last!
In low CO/SV (more flat Ees) however, despite lower SBP to start from, impact of reducing afterload (Ea) on BP is minimal, because lower vascular tonus is compensated by a massive increase in SV (afterload dependency!)
Don't forget that CVP influences lung edema as well, as it impedes lymphatic flow, the main protective mechanism against lung edema. Acute rise more dangerous than slow rise (lymphatic adaptations take time).
