A study of 12,015 older adults found that people who later had cardiovascular disease events showed worse frailty, intrinsic capacity and physical health-related quality of life up to a decade beforehand. Differences widened in the five years before an event, but the study does not show that functional decline causes cardiovascular disease or establish a screening strategy.
A study published online September 23 in JAMA Cardiology found that older adults who later experienced cardiovascular disease events had poorer functional health than matched peers as far as 10 years before the event. The analysis of 12,015 participants also found that gaps in frailty, intrinsic capacity and physical health-related quality of life widened during the five years before an event. These findings describe group-level differences over time.
Researchers led by Aung Zaw Zaw Phyo of Monash University in Melbourne analyzed data from the Aspirin in Reducing Events in the Elderly cohort. The nested case-control analysis included 2,403 people who experienced a cardiovascular event and 9,612 matched controls. The study compared changes in functional-aging measures over the years before an event, rather than examining only health status at the time of diagnosis.
Across the follow-up period, participants who later had an event showed higher frailty, lower intrinsic capacity and poorer physical health-related quality of life than controls. The differences became more pronounced in the five years before the event. The researchers reported faster increases in frailty scores and steeper declines in intrinsic capacity and physical quality of life among cases. These are group-level patterns, not a prediction that a particular person will develop cardiovascular disease.
Patterns were broadly similar across components of the study’s cardiovascular event composite, but timing varied. The report says differences appeared at least 10 years before heart failure and fatal coronary heart disease, while divergence for myocardial infarction and stroke occurred later. The supplied summary does not give event counts for each category or enough detail to compare the size of those differences.
Functional Changes May Widen the Assessment Window
The study reports that measures of physical function and frailty were poorer among participants who later experienced cardiovascular events, with differences appearing years before events and widening in the five years beforehand. The authors suggest these patterns may offer a prolonged window for closer clinical evaluation, but the analysis does not establish how the findings should be used in cardiovascular risk assessment.
That possibility is not the same as evidence that functional measures can reliably predict an individual event or that intervening on frailty will prevent one. The authors describe the findings as suggesting a prolonged window for closer clinical evaluation and early intervention. The study did not test a particular intervention or show that acting on these measures changes cardiovascular outcomes.

How Researchers Tracked Pre-Event Aging
The paper, 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. Researchers compared participants who experienced a cardiovascular event with matched controls, tracing several measures of function over time. The measures included two approaches to frailty, intrinsic capacity and physical health-related quality of life.
Because this was a nested case-control observational analysis, it can identify differences and trajectories associated with later events, but it cannot establish that functional decline caused those events. The supplied report does not specify all details of the cohort’s participant characteristics, follow-up procedures or how the findings might apply to populations beyond those studied. The study was published September 23, 2026, and was summarized by Medical Xpress in a report dated October 1.

Prediction and Prevention Remain Unproven
The findings do not establish whether functional decline contributes to cardiovascular disease, results partly from underlying disease, or reflects shared factors such as broader aging and other health conditions. The study reports differences between groups over time, but the supplied material does not show how accurately the measures identify which individuals will later have an event. It also does not establish a threshold for clinical screening.
It remains unclear whether programs aimed at improving or monitoring these functional measures would reduce cardiovascular events. The study’s observational design cannot answer that question. Results for particular event types also differed in when the groups began to diverge, and the available report does not provide enough detail to explain those differences or assess their clinical meaning.

Clinical Testing Would Need Further Evidence
The study’s findings support further research into whether functional-aging measures add useful information to existing cardiovascular assessments. Future studies would need to test how well these measures predict individual outcomes, whether patterns hold in other populations, and whether responding to functional decline changes health outcomes. Until then, the reported trajectories should be understood as associations that may inform closer evaluation, not as a stand-alone diagnostic tool or proven prevention method.

Key Questions
What did the study find?
People who later experienced cardiovascular events had worse frailty, intrinsic capacity and physical health-related quality of life than matched controls, with differences visible years before events and widening in the final five years.
How many people were included?
The analysis included 12,015 participants: 2,403 who experienced a cardiovascular event and 9,612 matched controls, drawn from the Aspirin in Reducing Events in the Elderly cohort.
Does functional decline cause cardiovascular disease?
The study does not establish cause and effect. It found an association between poorer functional measures and later events; its observational design cannot determine whether decline contributes to disease or reflects other processes.
Can these measures predict an individual’s heart attack or stroke?
The supplied report does not show that the measures can accurately predict an individual event or provide a clinical screening threshold. The findings describe differences between groups, not a validated personal prediction tool.
When did the differences appear?
Differences were reported up to a decade before cardiovascular events overall and at least 10 years beforehand for heart failure and fatal coronary heart disease. For myocardial infarction and stroke, the report says the groups diverged later but does not specify the timing.
