Content: At year 5, 2189 participants had complete data. Prevalence of HF stage A/B increased from 24% to 76% in black men, from 13% to 64% in white men, from 34% to 81% in black women, and from 13% to 56% in white women. Blacks were more likely to be in any stage or with morbidity at both time points because of higher risk factor prevalence. Of 33 participants with HF or HF deaths by year 30, 21 (64%) had been in stage A or B at year 5. Only 6 participants at year 5 in stage A (at risk) improved risk status at year 30. Conclusions: Risk for HF increased in participants from 1990 (age 22–37 years) to 2015 (age 47–62 years). Symptomatic HF or death from HF is associated with HF stage at 22 to 37 years of age. Blacks are disproportionately affected. WHAT IS NEW?
