Insights
Caffeine intake in cardiovascular patients showed no significant difference in daily consumption between groups. However, higher HDL cholesterol was observed in those without cardiovascular disease, suggesting a partial effect of caffeine on blood parameters.
Area of Science:
- Cardiology
- Nutritional Science
- Public Health
Background:
- Caffeine consumption is linked to chronic disease risk, with mixed effects on cardiovascular health.
- Understanding caffeine's role in cardiovascular patients is crucial for personalized health recommendations.
- Previous research indicates both beneficial and detrimental impacts of caffeine on cardiovascular outcomes.
Purpose of the Study:
- To investigate caffeine intake patterns in patients with cardiovascular diseases (CVDs).
- To compare caffeine consumption and blood parameters between CVD patients and a non-diagnosed control group.
- To explore the association between caffeine intake and specific cardiovascular risk factors.
Main Methods:
- A cross-sectional study involving 90 participants (50 CVD, 40 non-diagnosed) from a cardiology outpatient clinic.
- Data collection included demographic information, anthropometric measurements, and dietary intake via a Food Frequency Questionnaire.
- Blood parameters (cholesterol levels) and medical history of cardiovascular disease were assessed.
Main Results:
- No statistically significant difference in total daily caffeine consumption between CVD and non-diagnosed groups.
- The CVD group exhibited significantly higher Body Mass Index (BMI) and waist circumference.
- The non-diagnosed group showed significantly higher levels of HDL cholesterol compared to the CVD group.
Conclusions:
- Daily caffeine consumption may have a partial influence on blood parameters relevant to cardiovascular diseases, particularly in individuals with coronary artery disease.
- While total caffeine intake was similar, differences in HDL cholesterol suggest a nuanced relationship.
- Further research is warranted to elucidate the specific mechanisms and long-term effects of caffeine on cardiovascular health.
Abstract:
Background: Caffeine in the safe dose range has been associated with a reduction in the risk of chronic diseases. There is evidence that caffeine intake has both protective and negative effects on cardiovascular diseases. Aim: This study aimed to investigate caffeine intake in cardiovascular patients. Methods: The study sample was selected from individuals who applied to the Cardiology policlinic of Tekirdağ Namık Kemal University Hospital. A questionnaire was applied using face-to-face interview method to determine their demographic information, nutritional status and anthropometric measurements. Moreover, the nutritional status of the participants was determined by the Food Frequency Questionnaire and the type of cardiovascular disease was determined by a physician. The blood parameters of the sample for the last three months were questioned. The sample has been ninety people of whom fifty cardiovascular diseases (CVDs) were diagnosed and forty were non-diagnosed (ND). Results: The mean age of individuals (n = 90) was 43.2 ± 14.4. The BMI and waist circumference of the CVDs group were statistically significantly higher than the ND group (p < 0.001). While the total caffeine consumption of the ND group was 209.34 ± 143.85 mg/day, consumption of the CVDs group was 209.99 ± 196.76 mg/day. LDL cholesterol and total cholesterol did not show statistically significant difference between the two groups. However, HDL cholesterol was significantly higher in the ND group (p ≤ 0.001). Conclusion: Present results show that daily caffeine consumption may partially affect blood parameters associated with cardiovascular diseases, especially in the presence of coronary artery disease.
