🔥🫀ARNI showed superior cardioprotective effects.
May have renoprotective effects as per their molecular mechanism, but the evidence to date applies only to heart failure.
Future studies in CKD are needed, perhaps? 🤔

🔥SGLT2 Inhibitors: Game-changers!
They reduce HF hospitalisations, preserve GFR, slow CKD progression and improve outcomes in CRS.
🔹 Trials: DAPA-HF, EMPA-KIDNEY show mortality & renal benefits.
Do check out the link for the new SGLT2i toolkit there: theisn.org/initiatives/...

Decongestion Therapy
🔹 Loop diuretics = cornerstone
🔹 Use high doses for diuretic resistance; consider thiazides for synergy.
🔹 UF for refractory cases, but monitor renal function closely.
🔹 Aggressive diuresis improves outcomes even with transient ↑ creatinine.

Key Principles in Rx
1️⃣ Decongestion (diuretics/ultrafiltration).
2️⃣ Neurohormonal modulation (RAASI, SGLT2i).
3️⃣ Volume assessment (CVP, intrarenal Doppler).
4️⃣ Treat underlying systemic disease (e.g., sepsis).
5️⃣ Multidisciplinary care

What about management?
CRS management is about balance. It’s a tightrope walk between relieving congestion & preserving renal function. Let’s talk strategies.

Different imaging tech can also provide an overview of tissue damage and the overall function of the heart and kidneys

🔬 Biomarkers of cardiac and kidney injury may provide important information when and can serve to indicate early cardiac or renal injury, the repair process, and long-term sequelae doi.org/10.1161/CIR....

How do we diagnose it? doi.org/10.1161/CIRC...
We look at:
Biomarkers: NT-proBNP, cystatin C, NGAL, KIM-1
Imaging: Echo (CVP, LVEF), renal US (exclude obstruction)
Volume status: Clinical exam + POCUS

Congestion vs Perfusion
For years, we thought hypoperfusion drove CRS.
🔥Turns out, congestion is the bigger villain. High venous pressure, intra-abdominal pressure (IAP), and renal compression all hurt GFR.

🫀🔥Now, the million-dollar question: Why does this happen?
—it’s a cocktail of mechanisms: 🩺
Central players:
Congestion → ↓ Renal perfusion
RAAS & SNS activation → Maladaptive changes
Inflammation & oxidative stress → Organ damage

🔑What is CRS?
nature.com/articles/nrn...
Types of CRS:
1️⃣ Type I: Acute HF → AKI
2️⃣ Type II: Chronic HF → CKD
3️⃣ Type III: AKI → Acute HF
4️⃣ Type IV: CKD → Chronic HF
5️⃣ Type V: Systemic diseases (e.g., sepsis) → Combined dysfunction
