Worsening renal function during HF hospitalisation
Prospective Outcomes Study in Heart Failure
• 299 patients admitted with HFrEF to 8 EU centres
• Average age 69 (74% male)
• Median serum creatinine 137 mol/l (1.58 mg/dl)
= eCreat clearance 56ml/min [90% range 19-113
ml/min/1.73m2]
• 29% developed WRF (rise in serum creatinine by
at least 26 mol/l (0.3mg/dl)) during admission
• Factors independently associated with risk of
WRF:
– baseline serum creatinine
– pulmonary oedema on chest x-ray
– history of atrial fibrillation
• WRF had no impact on mortality (after adjustment
for co-morbidity), but prolonged length of stay up
by 2 days

Framingham: DM increases risk of HF by 1.82 ♂ and 3.15 ♀
CV Health Study (retired population): 33% of diabetic men and 45% of diabetic women develop HF in 5.5 years
Hospitalisation databases suggest that 11.8% of patients with diabetes have HF (vs. 4.5% of non-diabetics)
44% of acute HF admissions (USA) are coded as diabetic

Conclusions
Diabetes (and renal dysfunction) are VERY common in patients with heart failure
Strong association between poorer diabetic control and poorer micro- and macro-vascular outcome, including heart failure
Until recently tightening up diabetic control appears to have had only modest effects on CV outcome
The game may have changed with EMPA-REG
