Table 2.

Age-, sex-, race-standardized incidence rates and 95% confidence intervals (per 1000 person-years) of cardiovascular disease (heart failure, myocardial infarction, ischemic stroke), by income

Event	<$40K	$40–59K	Income $60–74K	$75–99K	≥$100K
Heart failure*	5.4 (4.2, 6.6)	4.1 (3.5, 4.6)	3.4 (2.7, 4.0)	3.1 (2.7, 3.6)	3.0 (2.4, 3.5)
Myocardial infarction†	2.1 (1.6, 2.7)	1.9 (1.5, 2.4)	1.4 (0.9, 1.9)	1.4 (1.0, 1.7)	1.6 (1.0, 1.5)
Stroke‡	3.2 (2.2, 4.2)	2.5 (2.0, 3.0)	2.3 (1.9, 2.7)	2.1 (1.8, 2.4)	2.3 (2.0, 2.6)

^*Prevalent heart failure was excluded from Model 3 when calculating incident heart failure

^†Prevalent coronary heart disease was excluded from Model 3 when calculating incident myocardial infarction

^‡Prevalent ischemic stroke was excluded from Model 3 when calculating incident ischemic stroke
