N-terminal Pro B-type Natriuretic Peptide and High-sensitivity Cardiac Troponin as Markers for Heart Failure and Cardiovascular Disease Risks According to Glucose Status (from the Multi-Ethnic Study of Atherosclerosis [MESA]).

The role of NT-proBNP and hs-cTnT levels in predicting heart failure (HF) and cardiovascular disease (CVD) events in persons with prediabetes (pre-DM) and diabetes mellitus (DM) is not well-established. We examined the individual and combined relations of N-terminal natriuretic peptide (NT-proBNP) and high-sensitivity cardiac troponin T (hs-cTnT) levels among asymptomatic adults with pre-DM and DM with the development of incident HF and CVD events. 5,584 participants with biomarker measures aged 45 to 84 years were included from the Multi-Ethnic Study of Atherosclerosis, of which 4,090 were normoglycemic, 799 had pre-DM, and 695 had DM at baseline and were followed for 12.4 ± 3.8 years. In those with DM, HF incidence rates per 1,000 person-years ranged from 3.2 to 39.4 across quartiles of NT-proBNP and 0.6 to 18.2 for hs-cTnT, respectively. Corresponding values for CVD incidence per 1,000 person-years ranged from 13.7 to 39.4 for NT-proBNP and 13.2 to 35.4 for hs-cTnT. Multivariate adjusted HRs were highest when both NT-proBNP and hs-cTnT were above versus below the median in those with pre-DM/DM (16.7 for incident HF and 2.1 for CVD events, both p <0.01). In conclusion, the combination of both biomarkers to traditional risk factors in participants who were normoglycemic or with pre-DM or DM improved risk prediction for both incident HF and total CVD events in an ethnically diverse population.
