  • Secondary analysis of the Look AHEAD randomised trial

Authors' conclusion

In T2D, NT-proBNP can inform HF risk assessment and identify individuals who are more likely to benefit from an ILI.

Study context

Population
Adults with T2D and overweight or obesity in the Look AHEAD trial
Participants
3,959 adults
Comparison
Intensive lifestyle intervention (ILI) vs diabetes support and education (DSE) across NT-proBNP categories
Primary endpoint
Risk of HF subtypes (heart failure with preserved ejection fraction (HFpEF): LVEF ≥50%; HFrEF: LVEF <50%) by baseline and 1-year change in NT-proBNP

Primary result

As reported in the abstract

HFpEF risk, ILI vs DSE, by NT-proBNP (subgroups)
ILI vs DSEHazard ratio (95% CI)
elevated baseline NT-proBNP (≥125 pg/mL)
0.47(0.24–0.90)
nonelevated baseline NT-proBNP
1.65(0.93–2.91)
stable or decreasing NT-proBNP at 1 year
0.58(0.34–0.99)
increasing NT-proBNP at 1 year
1.48(0.61–3.56)

Further findings

Heart failure with reduced ejection fraction (HFrEF) risk, ILI vs DSE, by NT-proBNP

ILI not significantly associated with HFrEF risk across baseline or 1-year change NT-proBNP categories
