Abstract
<p style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"><strong><span style="font-family:"Times New Roman",serif">Background: </span></strong><span style="font-family:"Times New Roman",serif">Atherosclerotic cardiovascular disease (ASCVD) is a global health challenge, prompting widespread use of conventional risk assessment tools (SCORE2 in Europe and the ASCVD Risk calculator in the United States) to guide preventive strategies. Emerging evidence indicates that NTproBNP may help refine risk stratification. We investigate whether measuring NTproBNP in primary prevention correlates with mortality and enhances prediction compared to conventional risk score stratification.</span></span></span></p> <p style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"><strong><span style="font-family:"Times New Roman",serif">Methods:</span></strong><span style="font-family:"Times New Roman",serif"> Utilizing National Health and Nutrition Examination Survey (NHANES) data (1999 to 2004) linked to the National Death Index, our cohort included individuals without a history of CVD at baseline and suitable for assessment of the ASCVD ACC/AHA risk score. Individuals were grouped based on computed 10-year risk (low: <5%; borderline: 5-7.5%; intermediate: 7.5-20%; high: ≥ 20%). NTproBNP levels were measured (Roche assay, cut-off > 125pg/mL considered as positive). Cox regression estimated the association between ASCVD risk categories, with or without NTproBNP, and all-cause and cardiovascular mortality.</span></span></span></p> <p style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"><strong><span style="font-family:"Times New Roman",serif">Results:</span></strong><span style="font-family:"Times New Roman",serif"> Among 5257 adults, 47% male, mean age 54 ± 9.1 years, the mean 10-year ASCVD risk was 8.17 ± 8.2%, grouped as: low: 53.3%; borderline: 11.5%; intermediate: 23.9%; and high: 11.3%. NTproBNP > 125pg/mL was measured in 12.2%, 16%, 23.2% and 48.6% individuals, respectively (p < 0.001). Over 16.2 ± 3.4 years, all-cause and cardiovascular death was 22.3% and 5.6%, respectively. Compared to low-risk, the hazard ratio (HR) for all-cause death increased to 2.85 (2.2-3.7), 5.6 (4.2-7.5), and 15.3 (11.7-19.9) for borderline, intermediate, and high-risk, respectively. A significant interaction with NTproBNP was observed (low: HR 1.96 (1.33-2.9); borderline: HR 2.5 (1.6-3.9); intermediate: HR 2 (1.6-2.6), high: HR 1.7 (1.4-2.2), p<0.01 for all interactions, see Fig. 1). For cardiovascular death, a significant interaction also occurred across the groups, but of higher magnitude in low and borderline groups (low: HR 3.2 (1.4-7.3); borderline: HR 5.5 (2.5-12.4), p < 0.001 for both).</span></span></span></p> <p><strong><span style="font-size:11.0pt"><span style="font-family:"Times New Roman",serif">Conclusion:</span></span></strong><span style="font-size:11.0pt"><span style="font-family:"Times New Roman",serif"> Our findings suggest that NTproBNP provides incremental predictive value, approximately doubling the hazard of all-cause death across all risk categories, and more than tripling the hazard of CV death in low/borderline risk groups, compared to ASCVD risk alone. The integration of NTproBNP measurements into risk assessment strategies could refine primary prevention approaches.</span></span></p>
