A study published in JAMA Cardiology found that people who later experienced cardiovascular disease events had worse measures of frailty, physical capacity and physical quality of life beforehand. The differences were present up to 10 years before events and widened in the five years leading up to them; the findings do not establish that functional decline causes cardiovascular disease.
A study of 12,015 older adults found that people who later experienced cardiovascular disease events had worse frailty, physical capacity and physical health-related quality of life years beforehand. Published online September 23 in JAMA Cardiology, the analysis found differences up to a decade before an event. The findings suggest functional changes may offer a prolonged period for closer clinical evaluation, but do not show that those changes cause cardiovascular disease.
Researchers led by Aung Zaw Zaw Phyo of Monash University analyzed participants in the Aspirin in Reducing Events in the Elderly cohort. The study compared 2,403 people who experienced a cardiovascular event with 9,612 matched controls. It examined trajectories in functional aging measures during the years before the event.
Compared with controls, the event group had higher frailty and lower intrinsic capacity, along with poorer physical health-related quality of life. These differences widened markedly during the five years before an event. Across the study period, the cases showed faster deterioration in the measured indicators, including increases in two frailty measures and declines in intrinsic capacity and physical quality of life.
The broad pattern appeared across components of the study’s cardiovascular disease composite, but the timing was not identical. The researchers reported that differences emerged at least 10 years before heart failure and fatal coronary heart disease, while divergence occurred later for myocardial infarction and stroke. The source report does not provide event counts for each component or describe these patterns as a diagnostic test.
A Longer Window for Clinical Review
The findings matter because cardiovascular risk is often discussed through conventional factors such as blood pressure and cholesterol, while this analysis tracks how people’s physical functioning changes over time. If similar patterns are confirmed in other populations, changes in frailty or capacity could prompt clinicians to review a person’s overall health and cardiovascular risks earlier than an event would otherwise make apparent.
The authors describe the findings as suggesting a prolonged opportunity for closer evaluation and early intervention. That is a research implication, not evidence that monitoring these measures prevents heart attacks, strokes or other events. The study also does not establish a threshold at which a change in function should trigger a particular clinical action. Individuals should discuss health concerns with a qualified health professional rather than interpret these findings as a personal prediction.

How the Study Tracked Functional Aging
The report, published as “Multidimensional Aging Trajectories Preceding Cardiovascular Events,” is a nested case-control analysis using data from the Aspirin in Reducing Events in the Elderly cohort. Researchers compared participants who had cardiovascular events with matched participants who did not, examining several measures rather than a single definition of decline.
Those measures included the Frailty Index, Fried frailty phenotype, intrinsic capacity and physical health-related quality of life. The results describe group-level trajectories before recorded events. They do not mean that every person with declining function will develop cardiovascular disease, or that functional decline is specific to heart or vascular conditions.
“Declines in functional aging markers were prominent before clinically apparent CVD.”

Limits of Prediction and Causation
The findings show an association between functional trajectories and later cardiovascular events; they do not establish that functional decline causes an event. Nor does the report show whether measuring these changes can accurately predict which individual will have a heart attack, stroke, heart failure or fatal coronary disease.
The source material does not specify the participants’ full demographic profile, the length of follow-up for each person, or the number of events within each cardiovascular category. It also does not establish whether the same patterns apply to younger adults or populations outside this cohort. Further work would be needed to test how useful these measures are in routine care and whether acting on them improves health outcomes.

Testing the Findings in Clinical Care
The study provides evidence for a long lead-up in group-level functional measures, but the next step is to determine whether those measures add useful information to existing cardiovascular assessments. Clinical usefulness and intervention effects remain untested in the findings described by the source report.
Further research could assess whether the trajectories hold in other groups, identify which changes are most informative, and test whether closer evaluation during the apparent window leads to better outcomes. Until then, the study supports attention to changing function as a research and clinical consideration, not a standalone screening rule or diagnosis.

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 visible years before the 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 from the Aspirin in Reducing Events in the Elderly cohort.
Does functional decline mean someone will have heart disease?
No. The study reports group-level associations and does not show that decline predicts an event for a particular person or that everyone with worsening function will develop cardiovascular disease.
Did the researchers show that early intervention prevents events?
No. The authors point to a possible window for closer clinical evaluation and early intervention, but the analysis did not test whether an intervention during that period prevents cardiovascular events.
