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 a decade beforehand. The differences widened in the five years before events, but the observational findings do not show that functional decline causes cardiovascular disease or that screening based on these measures prevents it.
Adults who later experienced cardiovascular disease events showed worse frailty, intrinsic capacity and physical health than matched peers years beforehand, according to a study published online Sept. 23 in JAMA Cardiology. Differences were visible up to a decade before an event and widened markedly in the final five years, the researchers reported, suggesting a long period in which clinicians could monitor changes in function.
Aung Zaw Zaw Phyo of Monash University in Melbourne and colleagues analyzed data from 12,015 participants in the Aspirin in Reducing Events in the Elderly (ASPREE) cohort. The group included 2,403 people who experienced a cardiovascular event and 9,612 matched controls. Researchers compared measures of functional aging over time before the events.
Compared with controls, participants who later had an event had higher frailty, lower intrinsic capacity and poorer physical health-related quality of life. Those differences grew more pronounced during the five years before an event. Across follow-up, the event group also had faster deterioration in measures of frailty and steeper declines in intrinsic capacity and physical health-related quality of life.
The study reported similar general patterns across components of its cardiovascular disease composite, but the timing differed. Differences appeared at least 10 years beforehand for heart failure and fatal coronary heart disease; for myocardial infarction and stroke, the researchers reported that divergence occurred later. The paper, titled “Multidimensional Aging Trajectories Preceding Cardiovascular Events,” was published in JAMA Cardiology in 2026.
A Longer Window for Clinical Attention
The findings suggest that cardiovascular events may be preceded by gradual changes in several aspects of health, rather than appearing against an otherwise stable functional profile. If similar patterns are confirmed, tracking frailty and physical function could help clinicians notice broader health changes well before a diagnosis or acute event. The authors describe this as a potential extended window for closer clinical evaluation and early intervention.
That possibility is not the same as evidence that functional assessments can predict an individual’s risk accurately or prevent an event. The study describes associations over time; it does not establish that declining function causes cardiovascular disease, identify a screening schedule, or test a specific intervention. Readers should not interpret changes in strength, mobility or daily function as a cardiovascular diagnosis. Decisions about symptoms or health assessments should be discussed with a qualified clinician.

How Researchers Tracked Aging
The analysis used a nested case-control design within the ASPREE cohort, comparing people who experienced cardiovascular events with matched participants who did not. Researchers examined multiple indicators rather than relying on a single measure: the Frailty Index, the Fried frailty phenotype, intrinsic capacity and physical health-related quality of life. Together, these measures capture different dimensions of functional health.
The study focused on trajectories in the years before events, not only measurements taken near diagnosis. Its central result is that differences were already present well in advance and generally became more pronounced as events approached. The publication is a research report, and the source summary does not provide details on the participants’ ages, individual event counts, or how the findings might apply to populations outside this cohort.

Limits on Risk Prediction
The reported results do not establish why functional decline and later cardiovascular events were associated, or whether one contributes to the other. It is also unclear from the available report whether the measures can reliably distinguish people who will experience an event from those who will not, or how much they add to existing clinical risk assessments. No tested intervention or screening protocol is described.
The findings come from participants in ASPREE, so their relevance to other age groups and populations is not established by the summary. The report also does not provide absolute event risks or enough detail to translate the group-level trajectories into an individual prognosis. Further research would be needed before these measures could be used to guide routine cardiovascular screening.
Evidence Needed Before Screening Changes
The immediate next step is further research to determine whether the observed trajectories appear in other populations and whether functional measures improve established cardiovascular risk prediction. Studies would also need to test whether closer evaluation or early interventions prompted by changes in function can improve outcomes. The supplied report does not identify a scheduled follow-up study or clinical guideline change.
For now, the findings add evidence that functional health can change years before cardiovascular disease becomes clinically apparent, but they do not support a new self-screening rule. Clinicians and patients can discuss changes in daily function as part of broader care, while cardiovascular risk and symptoms should be evaluated through appropriate professional assessment.
Key Questions
What did the study find?
People who later experienced cardiovascular events had worse frailty, intrinsic capacity and physical health than matched controls, with differences seen as far as a decade beforehand and widening in the five years before events.
How many people were included?
The analysis included 12,015 ASPREE participants: 2,403 who experienced a cardiovascular event and 9,612 matched controls.
Does functional decline cause cardiovascular disease?
The study does not establish cause and effect. It found an association between worsening functional measures and later cardiovascular events, but it did not show that decline causes disease.
Does this mean functional assessments can predict an individual’s heart risk?
Not on the evidence described in the report. Whether these measures improve individual risk prediction or support a particular screening approach remains unclear.
Which events showed the earliest differences?
The report says differences appeared at least 10 years before heart failure and fatal coronary heart disease. Divergence was reported later for myocardial infarction and stroke.
