Authors' conclusion

There was an alarming increase in cardiovascular hospitalizations among younger adults in the USA from 2008 to 2019, and disparities between those residing in low- and higher-income communities did not narrow.

Study context

Population
US adults aged 25–64 years hospitalized for acute myocardial infarction (AMI), HF or ischaemic stroke, 2008–2019
Exposure
Low-income vs higher-income communities; 2019 vs 2008
Outcome
Age-standardized annual hospitalization and in-hospital mortality rates for AMI, HF and ischaemic stroke
Follow-up
2008–2019

Main finding

As reported in the abstract

Age-standardized hospitalization rates (per 100 000), adults aged 25-64 years · 2008 to 2019

2008

155.0 (95% CI 154.6, 155.4)

AMI · HF 165.3 [164.8, 165.7] · Ischaemic stroke 76.3 [76.1, 76.7]

2019

160.7 (160.3, 161.1)

AMI · HF 225.3 [224.8, 225.8] · Ischaemic stroke 108.1 [107.8, 108.5]

2019 vs 2008 · AMI hospitalizations
absolute change +5.7 per 100 000 (CI 5.0–6.3); P < 0.001
Heart failure hospitalizations · increase over study period
absolute change +60.0 (CI 59.3–60.6); P < 0.001
ischaemic stroke hospitalizations · increase over study period
absolute change +31.7 (CI 31.2–32.2); P < 0.001

Observational data: associations, not effects.

Further findings

Hospitalization rates by community income

Significantly higher in low-income vs higher-income communities across all conditions; disparities did not narrow

In-hospital mortality · 2008–2019

Decreased for all conditions over the study period
