Elevated remnant cholesterol and low-grade inflammation each cause atherosclerotic cardiovascular disease (ASCVD); however, it is unknown whether joint elevation of both factors confers the highest risk. We tested the hypothesis that dual elevated remnant cholesterol and low-grade inflammation marked by elevated C-reactive protein is associated with the highest risk of myocardial infarction, ASCVD, and all-cause mortality. The Copenhagen General Population Study randomly recruited white Danish individuals aged 20–100 years in 2003–2015 and followed them for a median 9.5 years. ASCVD was cardiovascular mortality, myocardial infarction, stroke, and coronary revascularization. In 103,221 individuals, we observed 2,454 (2.4%) myocardial infarctions, 5,437 (5.3%) ASCVD events, and 10,521 (10.2%) deaths. The hazard ratios increased with each of stepwise higher remnant cholesterol and stepwise higher C-reactive protein. In individuals with the highest tertile of both remnant cholesterol and C-reactive protein compared to individuals with the lowest tertile of both, the multivariable adjusted hazard ratios were 2.2 (95%CI:1.9–2.7) for myocardial infarction, 1.9 (1.7–2.2) for ASCVD, and 1.4 (1.3–1.5) for all-cause mortality. Corresponding values for only the highest tertile of remnant cholesterol were 1.6 (1.5–1.8), 1.4 (1.3–1.5), and 1.1 (1.0–1.1), and those for only the highest tertile of C-reactive protein were 1.7 (1.5–1.8), 1.6 (1.5–1.7), and 1.3 (1.3–1.4), respectively. There was no statistical evidence for interaction between elevated remnant cholesterol and elevated C-reactive protein on risk of myocardial infarction (p = 0.10), ASCVD (p = 0.40), or all-cause mortality (p = 0.74). Dual elevated remnant cholesterol and C-reactive protein confers the highest risk of myocardial infarction, ASCVD, and all-cause mortality, that is, compared to either of these two factors individually. [Display omitted] • Dual elevated remnant-C and CRP was associated with the highest risk of ASCVD. • ASCVD risk is particularly relevant if remnant-C is ≥ 0.8 mmol/L and CRP ≥1.5 mg/L. • ASCVD risk was double in the highest tertile of both compared to the lowest.
