  • Cohort study
  • nationwide health examination cohort

Authors' conclusion

Elevated remnant-C levels confer an independent risk of MACE, most notably in young adults.

Study context

Population
Adults without history of myocardial infarction (MI) or ischemic stroke who underwent national health examinations in 2012
Participants
4,308,405 adults
Exposure
Remnant-C quartiles
Outcome
MACE (MI, ischemic stroke, CV death) by remnant-C quartile, overall and by age group (20-39, 40-64, ≥65 years)
Follow-up
Median 9.3 years

Main finding

As reported in the abstract

MACE components, highest vs lowest remnant-C quartile, by age
Highest remnant-C quartile vs Lowest remnant-C quartileAdjusted hazard ratio (95% CI)
MI, age 20-39
1.42(1.32–1.52)
ischemic stroke, age 20-39
1.30(1.19–1.42)
CV mortality, age 20-39
2.19(1.79–2.68)
MI, age ≥65
1.07(1.03–1.12)
ischemic stroke, age ≥65
1.12(1.08–1.16)
CV mortality, age ≥65
1.08(1.02–1.13)

Observational data: associations, not effects.

Further findings

Outcomeadjusted HR (95% CI)
Age 20-39 with optimal LDL-C (<100 mg/dL) but high remnant-C (≥30 mg/dL) (subgroup) — High remnant-C vs Lowest remnant-C quartile · MI1.24 (1.10–1.41)
Age 20-39 with optimal LDL-C (<100 mg/dL) but high remnant-C (≥30 mg/dL) (subgroup) — High remnant-C vs Lowest remnant-C quartile · ischemic stroke1.29 (1.10–1.52)
Age 20-39 with optimal LDL-C (<100 mg/dL) but high remnant-C (≥30 mg/dL) (subgroup) — High remnant-C vs Lowest remnant-C quartile · CV mortality1.83 (1.35–2.49)
