Little is known about the relationship between lipoprotein (a) [Lp(a)] and high-sensitivity C-reactive protein (hsCRP) and their joint association with atherosclerotic cardiovascular disease (ASCVD).The purpose of this study was to assess whether Lp(a)-associated ASCVD risk is modified by hsCRP in the context of primary prevention.The current study included 4,679 participants from the MESA (Multi-Ethnic Study of Atherosclerosis) Apolipoprotein ancillary data set. Cox proportional hazards models and Kaplan-Meier curves were used to assess the association among Lp(a), hsCRP, and time to cardiovascular disease (CVD) events.During a mean follow-up of 13.6 years, 684 CVD events occurred. A significant interaction was observed between Lp(a) and hsCRP (P = 0.04). With hsCRP2 mg/L, no significant CVD risk was observed at any level of Lp(a) from 50 mg/dL to100 mg/dL. However, with hsCRP ≥2 mg/L, a significant CVD risk was observed with Lp(a) of 50-99.9 mg/dL (HR: 1.36; 95% CI: 1.02-1.81) and Lp(a) ≥100 mg/dL (HR: 2.09; 95% CI: 1.40-3.13). Isolated elevations of either Lp(a) or hsCRP were not associated with increased CVD risk. In contrast, the combination of elevated Lp(a) (≥50 mg/dL) and hsCRP (≥2 mg/L) was independently associated with significant CVD risk (HR: 1.62; 95% CI: 1.25-2.10) and all-cause mortality (HR: 1.39; 95% CI: 1.12-1.72).Lp(a)-associated ASCVD risk is observed only with concomitant elevation of hsCRP. Individuals with concomitant presence of elevated Lp(a) and systemic inflammation have greater ASCVD risk and all-cause mortality, and thus may merit closer surveillance and more aggressive ASCVD risk management. |
