The value of NT-proBNP in cardiovascular risk assessment of patients with type 2 diabetes
Up to one in seven patients with type 2 diabetes (T2D) will develop heart failure in their lifetime.1
Co-existence of T2D and heart failure is associated with worse symptoms and quality of life, increased hospitalisations and higher mortality rates compared to patients without T2D.3
Heart failure is one of the earliest, most common and serious cardiovascular complications in patients with T2D.2
Even when all cardiovascular risk factors including blood pressure, smoking, cholesterol, triglycerides and blood glucose were optimally controlled, people with T2D still had a 21% higher risk for CVD and 31% higher risk for heart failure hospitalisation than people without T2D.4
There is a need to further individualise risk beyond the presence of accepted clinical risk factors.5
NT-proBNP may be the earliest sign to detect heart failure in people with T2D before structural and functional changes become apparent on imaging6,7

Patients with T2D and an elevated NT-proBNP are at higher risk of unplanned CV hospitalisation or death within the next 12 months8
NT-proBNP is a stronger predictor of CV related event of death for patients with T2D over HbA1c and albuminuria9,10
NT-proBNP may help identify people with T2D at risk of heart failure hospitalisation (HFH) six months before the cardiac event, regardless of the history of heart failure11

2022 AHA/ACC/HFSA Guideline
'For patients at risk of developing HF, natriuretic peptide biomarker-based screening followed by team-based care, including a cardiovascular specialist optimising GDMT, can be useful to prevent the development of LV dysfunction or new-onset HF.'12
ESC position paper 2016
NP measurement by general practitioners and diabetologists in high-risk populations such as those with hypertension or diabetes mellitus helps the targeted initiation of preventive measures, including medicine up-titration of renin–angiotensin system antagonists and, therefore, prevent or slow the development of HF.13
Consensus document by the HFA of the ESC
'Screening might be considered in patients with conditions predisposing to HF, such as hypertension and diabetes, to identify subclinical HF that warrants initiation of cardiac protective therapies. A possible alternative to the current approach to HF screening in hypertensive and diabetic individuals is a two-step screening with the measurement of NPs or hs-troponin and then transthoracic echocardiogram (TTE), when circulating biomarkers are either elevated or rising.'14
