A JAMA Cardiology study found that people who later experienced cardiovascular disease events had worse frailty, intrinsic capacity and physical health measures than matched controls as far as 10 years beforehand. The observational findings show an association, not proof that functional decline causes cardiovascular disease or that tracking these measures prevents events.

Older adults who later experienced cardiovascular events had worse frailty, physical capacity and health-related quality of life than matched controls as far as 10 years beforehand, according to a study published online Sept. 23 in JAMA Cardiology. The gaps widened in the five years before an event. The findings show a long-term association between declining function and cardiovascular events, but do not establish that functional decline causes them.

Aung Zaw Zaw Phyo of Monash University in Melbourne and colleagues analyzed participants in the Aspirin in Reducing Events in the Elderly cohort. The analysis compared 2,403 people who had a cardiovascular event with 9,612 matched controls. Researchers examined trajectories in functional aging measures in the years leading up to events.

People in the event group had consistently worse profiles than controls, including higher frailty, lower intrinsic capacity and poorer physical health-related quality of life. The differences were present up to a decade before an event and widened markedly during the five years immediately preceding it. Over time, the event group also showed faster deterioration across these measures.

The researchers reported greater increases in frailty, measured with both the Frailty Index and Fried phenotype, and steeper declines in intrinsic capacity and physical health-related quality of life. Similar patterns appeared across cardiovascular event types, but the timing differed: divergence was reported at least 10 years beforehand for heart failure and fatal coronary heart disease, while it appeared later for heart attack and stroke.

A Longer Window for Clinical Review

The findings matter because cardiovascular risk is often discussed in relation to specific conditions and conventional risk factors, while this study tracks broader changes in function over time. If clinicians observe worsening frailty or physical capacity, those measures may provide additional information about a person’s health trajectory. The authors suggest that the pattern could support closer clinical evaluation and earlier intervention, although this study did not test a screening strategy or show that acting on functional measures prevents an event.

The time span is also relevant: differences were detectable years before a clinically apparent event, rather than emerging only shortly beforehand. That may encourage further research into whether routine assessments of function can help identify people who need cardiovascular evaluation. For readers, the result is a population-level association—not a way to predict an individual’s heart attack or stroke from frailty alone, and not a substitute for professional assessment.

How the Study Tracked Function

The study, titled Multidimensional Aging Trajectories Preceding Cardiovascular Events, was published in JAMA Cardiology and used data from the Aspirin in Reducing Events in the Elderly cohort. Its nested case-control design allowed researchers to compare people who experienced cardiovascular events with matched participants who did not, following functional measures across the years before the event.

The measures captured different aspects of health: frailty, intrinsic capacity and physical health-related quality of life. They are not the same as a cardiovascular diagnosis. The report describes changes in these measures before events, and the study’s observational design means the results show a pattern over time rather than establishing why the pattern occurred.

“Declines in functional aging markers were prominent before clinically apparent CVD.”

Association Does Not Show Cause

The analysis does not establish that functional decline causes cardiovascular disease, or that cardiovascular disease was already developing throughout the full period when functional measures differed. Nor does it show that tracking frailty or intrinsic capacity can reliably predict which individual will have an event. The report does not provide evidence that a particular intervention based on these measures reduces cardiovascular events.

The supplied study summary also does not detail the participants’ full demographic profile, the precise follow-up schedule for each measure or how the findings might apply beyond this cohort. The reported pattern varies by event type, and the reasons for earlier divergence before heart failure and fatal coronary disease remain unclear. Further research is needed before the findings can be translated into a specific clinical prediction or screening recommendation.

Testing Clinical Use in Future Studies

The study authors point to closer clinical evaluation and early intervention as possible implications, but the report does not specify a follow-up trial or a planned change to clinical guidance. The next step for researchers will be to test whether functional measures add useful information to established cardiovascular assessments and whether responding to changes in function improves outcomes.

Until such evidence is available, the finding should be read as an association in an older-adult cohort rather than a new diagnostic rule. People concerned about declining function or cardiovascular symptoms should discuss their situation with a qualified health professional; the study itself does not provide individual medical advice.

Key Questions

What did the study find?

People who later had cardiovascular events showed worse frailty, intrinsic capacity and physical health-related quality of life than matched controls, with differences apparent years beforehand and widening near the event.

How many people were included?

The analysis included 12,015 participants from the Aspirin in Reducing Events in the Elderly cohort: 2,403 people who experienced an event and 9,612 matched controls.

Does functional decline cause cardiovascular disease?

The study does not show cause and effect. Its observational findings identify an association between worsening functional measures and later cardiovascular events.

Did the timing differ by event type?

Yes. The report says differences appeared at least 10 years before heart failure and fatal coronary heart disease, while divergence occurred later before myocardial infarction or stroke.

Can these measures predict an individual’s risk?

The study does not establish that frailty or physical function measures can predict an individual event or show that using them to guide care prevents cardiovascular disease.
