Physical frailty and cognitive function among men with cardiovascular disease

Area of Science:

• Gerontology
• Cardiology
• Neuroscience

Background:

• Cardiovascular disease (CVD) is prevalent in elderly populations.
• Physical frailty is a common condition associated with adverse health outcomes.
• Cognitive decline is a significant concern in aging individuals, particularly those with chronic diseases.

Purpose of the Study:

• To investigate the association between physical frailty and cognitive function in elderly men with a history of CVD.
• To determine if frailty status or its components correlate with specific cognitive domains.

Main Methods:

• The study included 324 community-dwelling men with chronic CVD, aged 77.2 ± 6.4 years.
• Physical frailty was assessed using the Fried phenotypic model.
• Cognitive function was evaluated using computerized tests across multiple domains, with linear regression analyses performed.

Main Results:

• 28% of participants were frail and 37% were pre-frail.
• Frailty severity was significantly associated with global cognitive function, particularly in executive function and attention domains.
• Gait speed was linked to overall cognitive performance and all assessed cognitive domains, while activity was not.

Conclusions:

• Frail and pre-frail men with CVD exhibit impaired cognitive function, especially in non-memory-related areas.
• These findings suggest a strong link between physical health and cognitive status in this population.
• Further research is needed to explore underlying mechanisms and develop interventions.
