[Cardiovascular effects of everyday coffee consumption]

Area of Science:

• Cardiovascular Physiology
• Nutritional Science
• Pharmacology

Context:

• Existing research focused on acute caffeine effects, with limited data on regular coffee consumption's cardiovascular impact.
• Recent studies systematically investigate the long-term cardiovascular effects of daily coffee intake.
• Understanding coffee's influence on cardiovascular markers is crucial for public health recommendations.

Purpose:

• To systematically evaluate the cardiovascular effects of regular daily coffee consumption.
• To compare the effects of acute versus chronic caffeine/coffee intake on blood pressure and pulse.
• To investigate the relationship between coffee consumption, plasma lipids, and coronary heart disease prevalence.

Summary:

• Acute caffeine intake transiently increases systolic and diastolic blood pressure and decreases pulse rate.
• Repeated caffeine administration leads to diminished blood pressure response, and chronic coffee consumption shows only marginal blood pressure changes.
• Plasma lipids are largely unaffected by caffeine but may slightly increase with boiled coffee; thermogenic effects remain unclear, and coronary disease prevalence appears independent of coffee intake.

Impact:

• Provides evidence that regular coffee consumption has limited adverse cardiovascular effects, contrary to some concerns about acute caffeine intake.
• Suggests that the cardiovascular system adapts to regular caffeine exposure, mitigating the acute pressor response.
• Informs dietary guidelines and public perception regarding the cardiovascular safety of moderate coffee consumption.
