Changes in Frailty Patterns Following Cardiovascular Events in Older Adults

Overview

This longitudinal study of 19,111 older adults without prior cardiovascular disease (CVD) found that incident CVD events significantly increase frailty trajectories, particularly after hospitalization for heart failure and stroke. Factors such as age over 80, female sex, living alone, and residing in regional or remote areas were associated with greater frailty burden post-CVD event.

Background

Cardiovascular disease is the leading cause of death and disability among older adults globally and is closely linked with frailty, a syndrome marked by cumulative deficits increasing vulnerability to adverse outcomes. While frailty is common in older adults with CVD and worsens prognosis, it remains unclear how incident CVD events influence frailty progression over time. Understanding these trajectories and the modifying factors is critical to improving post-CVD management and targeting interventions to reduce frailty-related complications.

Data Highlights

Key Findings

• Incident CVD events cause a significant short-term increase in frailty measured by both the Frailty Index and Fried phenotype.
• Only the Frailty Index continues to increase over time following a CVD event, indicating progressive frailty burden.
• Hospitalization for heart failure and stroke are associated with the greatest increases in frailty compared to myocardial infarction.
• Older age (>80 years), female sex, living alone, and residing in regional or remote areas are linked to higher frailty burden post-CVD event.
• Socioeconomic status, polypharmacy, and number of chronic conditions also influence frailty trajectories but were less emphasized.

Clinical Implications

Healthcare providers should incorporate frailty assessment and management into the care of older adults following incident CVD events, especially after heart failure and stroke. Targeted interventions are needed for high-risk groups such as the very elderly, women, those living alone, and individuals in regional or remote locations to minimize frailty-related complications and improve long-term outcomes.

Conclusion

Incident cardiovascular events significantly accelerate frailty progression in older adults, with specific demographic and social factors exacerbating this effect. Recognizing and addressing frailty as part of CVD management is essential to optimize care and reduce adverse outcomes in this vulnerable population.
