Incidence of HF in FHS and CHS participants from 1990–2009.

	1990–1999	2000–2009	p-value
Number at risk	8762	6455
Person-years follow-up	70548	45155
Age at start of window, y	73±8	74±9
Women, n (%)	5128 (59%)	3954 (61%)
All HF*
HF events, n	1367	1157
Std HF incidence per 1000	19.7 (18.4, 21.0)	18.9 (17.7, 20.1)	0.37
HFREF
HFREF events, n	491	353
Std HF incidence per 1000	6.6 (5.9, 7.3)	6.2 (5.4, 6.9)	0.40
HFPEF
HFPEF events, n	309	431
Std HF incidence per 1000	4.7 (4.2, 5.2)	6.8 (6.1, 7.5)	<0.001

Participants were ≥60 years of age at the start of each decade. Std HF incidence= reported as n (95% confidence interval), standardized to age- and sex-specific 2010 (ages 60–95) US population rates, per 1 year follow up.

^*Some HF events had undetermined LVEF. HFREF and HFPEF= heart failure with reduced (<50%) and preserved (≥50%) left ventricular ejection fraction.
