This figure depicts the reclassification of cardiovascular health (CVH) in young adults using the Life's Simple 7 (LS7) score and the Life's Essential 8 (LE8) Score. LS7 scores of 0-4, 5-9, and 10-14 were defined as poor, intermediate, and ideal CVH, respectively. LE8 scores of <50, 50-79, and ≥80 were defined as poor, intermediate, and ideal CVH, respectively. Of the 1.7 million individuals categorized as poor CVH by the LS7 score, 1.6 million (94.1%) remained in the poor CVH category and 0.1 million (5.9%) were reclassified to intermediate CVH when classified by the LE8 score. Of the 46.1 million individuals categorized as intermediate CVH by the LS7 score, 35.6 million (77.2%) remained in the intermediate CVH category, 8.1 million (17.6%) were reclassified as poor CVH, and 2.3 million (5.0%) were reclassified to ideal CVH by the LE8 score. Of the 40.1 million individuals categorized as ideal CVH by the LS7 score, 21.1 million (52.6%) remained in the ideal CVH category, 18.9 million (47.1%) were reclassified as intermediate CVH, and 0.1 million (0.2%) were reclassified to poor CVH by the LE8 score.
