The prevalences of adverse left ventricular (LV) outcomes were estimated by age. Age groups 55–59 and 60–64 years were combined due to small sample sizes in some race-sex groups at age 60–64 years. Diastolic dysfunction and stage B abnormalities are shown after age 40–44 years due to unavailability of measures at younger ages (see Methods). P-values are as follows: prs, comparison by race-sex group; pl, linear trend with age; plxrs, age*race-sex interaction; pq, quadratic trend with age. Blacks had higher prevalences than whites of all adverse LV outcomes, and race-sex differences were statistically significant for adverse geometry overall, concentric remodeling, concentric hypertrophy, and diastolic dysfunction. The minimum and maximum sample sizes underlying any data point are as follows: overall 200 (for adverse LV geometry at age 40–44 years) to 2070 (for diastolic dysfunction at age 50–54 years); among Black men 35 (for LV geometry at age 35–39 years) to 351 (for diastolic dysfunction at age 50–54 years); among Black women 66 (for any stage B abnormality at age 40–44 years) to 563 (for diastolic dysfunction at age 50–54 years); among White men 29 (for any stage B abnormality at age 40–44 years) to 535 (for diastolic dysfunction at age 50–54 years); and among White women 40 (for any stage B abnormality at age 40–44 years) to 621 (for diastolic dysfunction at age 50–54 years).
