A higher BMI-proteomic score was associated with an increased risk of ischemic heart disease compared to the lowest quartile (HR 1.49; 95% CI 1.32-1.67; P<0.001), independent of actual BMI.

Does a higher BMI-proteomic score associate with an increased risk of cardiovascular disease subtypes in individuals free of CVD at baseline?
A proteomic signature of BMI is significantly associated with a higher risk of ischemic heart disease independent of actual BMI, suggesting its potential as a complementary risk marker.
Effect estimate: HR 1.49 (95% CI 1.32-1.67)

BACKGROUND: Obesity, defined by body mass index (BMI) alone, is a metabolically heterogeneous disorder with distinct cardiovascular manifestations across individuals. This study aimed to investigate the associations of a proteomic signature of BMI with risk of major subtypes of cardiovascular disease (CVD). METHODS: A total of 40 089 participants from UK Biobank, free of CVD at baseline, had complete data on proteomic data measured by the Olink assay. A BMI-proteomic score (pro-BMI score) was calculated from 67 pre-identified plasma proteins associated with BMI. RESULTS: A higher pro-BMI score was significantly associated with higher risks of ischemic heart disease (IHD) and heart failure (HF), but not with risk of stroke. Comparing the highest with the lowest quartiles, the adjusted hazard ratio (HR) for IHD was 1.49 (95% CI, 1.32-1.67) (P-trend < 0.001), and the adjusted HR for HF was 1.52 (95% CI, 1.25-1.85) (P-trend < 0.001). Further analyses showed that the association of pro-BMI score with HF risk was largely driven by the actual BMI, whereas the association of the pro-BMI score with IHD risk was independent of actual BMI and waist-to-hip ratio (WHR). The association between pro-BMI score and IHD risk appeared to be stronger in the normal BMI group than other BMI groups (P-interaction = 0.004) and stronger in the normal WHR group than the high WHR group (P-interaction = 0.049). CONCLUSIONS: Higher pro-BMI score is significantly associated with higher IHD risk, independent of actual BMI levels. Our findings suggest that plasma proteins hold promise as complementary markers for diagnosing obesity and may facilitate personalized interventions.
Ma et al. (Fri,) conducted a cohort in Cardiovascular disease (n=40,089). BMI-proteomic score (pro-BMI score) vs. Lowest quartile of pro-BMI score was evaluated on Ischemic heart disease (IHD) (HR 1.49, 95% CI 1.32-1.67, p=<0.001). A higher BMI-proteomic score was associated with an increased risk of ischemic heart disease compared to the lowest quartile (HR 1.49; 95% CI 1.32-1.67; P<0.001), independent of actual BMI.
