The For Kidneys Sake podcast series is brought to you by Imperial College Healthcare NHS Trust and North West London Integrated Care Board (NWL NHS)
This podcast episode explores the intersection of chronic kidney disease (CKD) and heart failure, providing guidance for managing patients with both conditions. Hosts Prof Jeremy Levy and Andrew Frankel, consultant nephrologists, are joined by Dr Dominique Auger, a consultant cardiologist specialising in heart failure.
The discussion focuses on the shared pathophysiology of CKD and heart failure, optimising treatments, and addressing common clinical concerns in primary care.
Top Three Key Messages

1. CKD and Heart Failure Coexistence:

• CKD and heart failure frequently occur together, with CKD increasing the risk of cardiovascular disease and heart failure.
• Both conditions share overlapping treatments, including ACE inhibitors, ARBs, SGLT2 inhibitors, and MRAs, which improve survival, reduce symptoms, and decrease hospitalisations.

2. GFR Decline and Kidney Forgiveness:

• A decline in GFR is expected with effective therapies like RAS inhibitors and SGLT2 inhibitors.
• For heart failure with CKD, GFR reductions of up to 50% or creatinine increases to 260 µmol/L are acceptable, as kidneys often stabilise ("the kidneys forgive"). Therapy should continue with careful monitoring unless hyperkalaemia or other severe complications arise.

3. Role of Diuretics:

• Diuretics are essential for symptom control (e.g., relieving oedema and breathlessness) but have no prognostic benefit in heart failure.
• They are safe to use in CKD and heart failure, often requiring higher doses in CKD patients due to kidney resistance, and are useful for managing hyperkalaemia as well.

This episode underscores the importance of integrated, aggressive management of both CKD and heart failure, with a focus on optimising therapies that balance efficacy with patient safety.
