Heart, kidney and metabolic burden linked to later heart risk
An observational analysis of 2,968 CARDIA participants and 4,294 MESA participants linked accumulated burden to unfavorable heart structure and function and higher cardiovascular event risk.
Our read
Populations- Studied:
- Cohort study of participants in young and mid-to-late adulthood, 8.9 and 8.7 years
- What changed:
- Risk of major cardiovascular events was higher with greater cumulative burden: hazard ratio 2.35 in CARDIA and 1.71 in MESA
- The catch:
- Whether reducing accumulated burden lowers cardiovascular risk was not measured
- Why it’s aging research:
- It bears on staying healthy in midlife and later life.

CARDIA included 2,968 participants averaging 25 years old at enrollment, 55% women; MESA included 4,294 averaging 61, 53% women. This observational analysis tracked cumulative cardiovascular-kidney-metabolic burden: combined problems involving the heart, kidneys and the body’s handling of energy.
Higher accumulated burden was linked to less favorable heart structure and function on later ultrasound scans in both cohorts. For each increase in burden equal to one standard deviation—a measure of variation among participants—the adjusted hazard ratio, a measure of relative risk, for major cardiovascular events was 2.35 in CARDIA and 1.71 in MESA. Median follow-up after the burden-assessment period was 8.9 and 8.7 years, respectively. The authors identified accumulated body fat as a modifiable target for earlier prevention.
Why it matters
Heart, kidney and metabolic health across adulthood may help identify opportunities for earlier prevention of cardiovascular disease as people age.
Caveats
The analysis did not test whether reducing accumulated burden lowered cardiovascular risk. The findings were reported in a conference abstract.
