Closely timed diagnoses linked to higher heart failure risk
Over a median 15.3 years, heart failure occurred in 20.3% of adults with clustered diagnoses, compared with 6.2% whose obesity was diagnosed first.
Our read
Populations- Studied:
- Cohort study of 72,361 adults aged 18-75 years with cardiometabolic multimorbidity, median 15.3 years
- What changed:
- Heart failure was higher with simultaneous diagnoses: 20.3% against 6.2% in the obesity-first group
- The catch:
- Recorded diagnosis dates may not reflect when diseases began
- In the record:
- The 34th paper on low income with results in people; 50 on record in all.
- Why it’s aging research:
- It measures an outcome that worsens with age.

Adults aged 18–75 with multiple conditions involving metabolism and heart health—72,361 participants in the All of Us Research Program—were assessed in an observational study using past health records. Their mean age was 59.9, and 63.2% were female. The researchers grouped participants by diagnosis timing. “Simultaneous” meant multiple diagnoses within 365 days. Disease-first groups required at least 365 days between the first diagnosis and a subsequent condition.
Over a median 15.3 years, 9,633 participants (13.3%) developed heart failure. Those diagnosed first with obesity, high blood pressure or type 2 diabetes had lower heart failure risk than the simultaneous group after adjustment for age, sex and other recorded differences. Lower income was associated with greater odds of simultaneous diagnoses than higher income.
Why it matters
Heart failure becomes more common with age. The authors suggested that the timing of related diagnoses may complement existing ways of assessing its risk.
Caveats
Recorded diagnosis dates may not reflect when diseases began, and differences in access to care may have influenced the patterns. These conference-abstract findings concern adults aged 18–75 who already had multiple conditions involving metabolism and heart health.
