Association between exercise habit changes and mortality following a cardiovascular event

Area of Science:

• Cardiology
• Gerontology
• Public Health

Background:

• Cardiovascular disease (CVD) poses a significant health risk to older adults.
• Understanding the impact of lifestyle changes, particularly exercise, post-CVD is crucial for improving outcomes.

Purpose of the Study:

• To examine the association between changes in exercise habits after a cardiovascular event and mortality rates in individuals aged 60 and older.

Main Methods:

• A cohort of 6076 adults aged ≥60 years was analyzed between 2003-2012.
• Participants were categorized into four groups based on exercise habit changes post-CVD diagnosis: persistent non-exercisers, exercise dropouts, new exercisers, and exercise maintainers.
• Inverse probability of treatment weighting was used to adjust for baseline differences.

Main Results:

• Compared to persistent non-exercisers, new exercisers and exercise maintainers showed a significantly reduced risk of all-cause mortality (HR 0.73 and 0.53, respectively).
• Both new exercisers and exercise maintainers had lower rates of non-cardiovascular deaths (IR 2.3 for both groups).
• A significant trend towards reduced cardiovascular death was observed in new exercisers and exercise maintainers (p < 0.001).

Conclusions:

• Positive changes in exercise habits, such as starting or maintaining physical activity after a cardiovascular event, are linked to lower mortality in older adults.
• These findings support public health initiatives encouraging physical activity for older adults with CVD.
