Bodies Show Decline Years Before Heart Attacks and Strokes Strike
Frailty, weakness, and declining physical capacity appear up to a decade before heart attacks and strokes, a study of 12,015 older adults finds.

In brief
- Researchers analyzed 12,015 older adults from the ASPREE cohort: 2,403 who had a cardiovascular event and 9,612 matched controls.
- People who later had a cardiovascular event showed higher frailty, lower intrinsic capacity, and worse physical quality of life for up to a decade beforehand.
- The functional gap widened sharply in the five years before the event, and appeared earliest (10+ years) for heart failure and fatal coronary heart disease.
People who go on to have a heart attack, stroke, or other cardiovascular event tend to show measurable physical decline many years before anything goes visibly wrong with their hearts, according to a study published September 23 in JAMA Cardiology.
The findings suggest that functional decline — a gradual loss of strength, resilience, and overall physical capacity — is not merely a consequence of cardiovascular disease but often a warning sign that precedes it by up to a decade.
What the researchers did
Aung Zaw Zaw Phyo, Ph.D., of Monash University in Melbourne, Australia, and colleagues wanted to know whether the trajectory of a person's physical function changes in the years leading up to a cardiovascular event. To answer that question, they turned to a large Australian and American research cohort known as ASPREE (Aspirin in Reducing Events in the Elderly), which followed older adults over many years.
The analysis included 12,015 participants: 2,403 people who experienced a cardiovascular disease event — such as a heart attack, stroke, heart failure, or fatal coronary heart disease — and 9,612 matched controls who did not. Matching means the researchers compared each case with similar participants of the same age and background, which helps isolate the effect of the event itself.
The team tracked several established measures of aging-related function:
- Frailty, measured two ways: a Frailty Index, which counts accumulated health deficits, and the Fried phenotype, which assesses weakness, exhaustion, slow walking speed, low physical activity, and weight loss.
- Intrinsic capacity, a broader measure combining physical and mental abilities that together determine a person's level of functioning.
- Physical health-related quality of life, a self-reported measure of how much health problems interfere with daily physical functioning.
What they found
The results were striking in their consistency. People who eventually suffered a cardiovascular event had worse scores across all these measures for up to a decade before the event, compared with matched controls who remained event-free. They were more frail, had lower intrinsic capacity, and reported poorer physical quality of life.
In the final five years before the event, the gap widened markedly. Cases not only started worse — they deteriorated faster. The researchers quantified this with statistical measures called beta coefficients: greater increases in frailty over time (Frailty Index: β = 0.78; Fried phenotype: β = 0.05) and steeper declines in intrinsic capacity (β = −0.34) and physical health-related quality of life (β = −0.55).
The timing of the divergence also varied depending on the type of cardiovascular event. For heart failure and fatal coronary heart disease, the functional gap between cases and controls appeared at least 10 years before the event. For heart attack and stroke, the divergence occurred later.
What it means
The authors interpret their results as evidence that declines in functional aging markers may represent the culmination of progressive aging across multiple body systems — not simply the aftermath of a sudden cardiac crisis.
"Results of this nested case-control study show that declines in functional aging markers were prominent before clinically apparent CVD, suggesting that they may represent the culmination of progressive multisystem aging and indicating a prolonged window of opportunity for closer clinical evaluation and early intervention," the authors write.
That "prolonged window" is the practical takeaway: if declining function signals rising cardiovascular risk years in advance, doctors could in principle use simple functional assessments — walking speed, frailty screening, self-reported physical function — to identify people who warrant closer monitoring and preventive care long before a crisis.
Caveats to keep in mind
This was an observational, nested case-control study, meaning it can identify associations but cannot prove that functional decline causes cardiovascular events — or that intervening on frailty would prevent them. Both frailty and cardiovascular disease share common underlying causes, such as chronic inflammation and aging of blood vessels, so one may not drive the other. The study population consisted of older adults enrolled in an aspirin trial, which may limit how well the findings apply to younger people or other populations.
Still, the study adds to a growing body of evidence that cardiovascular disease rarely arrives out of nowhere. The body, it seems, often telegraphs trouble years in advance — quietly, through creeping frailty and fading physical capacity — if clinicians know what to measure.
