Coffee Consumption Correlates With Better Cognitive Performance in Patients With a High Incidence for Stroke.

Area of Science:

• Cardiology
• Neurology
• Nutritional Science

Background:

• Atrial fibrillation is a known risk factor for cognitive impairment.
• Coffee consumption offers cognitive benefits in healthy individuals, but its effect in patients with atrial fibrillation is debated.
• This study investigated the impact of regular coffee consumption on cognitive decline in elderly patients diagnosed with atrial fibrillation.

Purpose of the Study:

• To examine the association between regular coffee consumption and cognitive performance in elderly individuals with atrial fibrillation.
• To explore the relationship between coffee intake and inflammatory markers in this patient group.
• To determine if coffee consumption can mitigate cognitive decline in a vulnerable population.

Main Methods:

• Cognitive function was assessed using a comprehensive neurocognitive test battery, including the Montreal Cognitive Assessment, Trail-Making Test, semantic fluency, and Digit-Symbol-Substitution Test.
• Daily coffee consumption was quantified via a structured nutrition questionnaire.
• Inflammatory markers, high-sensitivity C-reactive protein (hs-CRP) and interleukin-6 (IL-6), were measured. Linear mixed-effects models were employed for data analysis, controlling for potential confounders.

Main Results:

• Higher coffee consumption (more than 5 cups/day) was associated with a significantly improved cognitive construct score compared to lower intake (<1 cup/day) (p=0.048).
• While the Montreal Cognitive Assessment scores showed a positive trend with increased coffee intake, the difference was not statistically significant (p=0.163).
• Inflammatory markers, particularly IL-6, showed a significant decrease with higher coffee consumption (p=0.017), while hs-CRP showed a non-significant trend towards reduction.

Conclusions:

• Coffee consumption in patients with atrial fibrillation may be linked to enhanced cognitive performance.
• Higher coffee intake appears to be associated with reduced systemic inflammation in this population.
• Further research is warranted to validate these findings and explore the potential role of coffee in dietary recommendations for atrial fibrillation management.
