Values are mean ± SD or n (%). Definitions for elevated and low cardiovascular risk: 10-year risk: elevated ≥7.5%, low <7.5%; 30-year risk: elevated ≥20%, low <20%. All P values <0.001 from analysis of variance (ANOVA) tests for continuous variables and chi-square tests for categoric variables across low 10-year/low 30-year risk vs low 10-year/ elevated 30-year risk vs elevated 10-year risk categories.
a
A total of 1,370 young adults had elevated 10-year but low 30-year risk, and they were included in the elevated 10-year risk group.
ASCVD = atherosclerotic cardiovascular disease; HDL = high-density lipoprotein; LDL = low-density lipoprotein.
