Even though coffee consumption has been clearly related to a number of benefits to the cardiovascular system, its effect on blood pressure (BP) has not been fully elucidated. In this sub- analysis of the Brisighella Heart Study (BHS), we compared central and peripheral BP values in a sub-cohort of 720 men (47.9%) and 783 women (52.1%) reporting the drinking of different amounts of coffee each day, for whom a full set of clinical, laboratory and hemodynamic parameters was available. According to our observations, moderate coffee drinking was associated to either higher levels of systolic BP (SBP) compared to those with heavy coffee consumption or lower SBP than that in the non-coffee drinking group (p-value for trend less than 0.05). In particular, people who drank 2 cups of coffee per day and people who drank greater than 3 cups per day had lower SBP than non-coffee drinkers by 5.2 ± 1.6 mmHg (p = 0.010) and 9.7 ± 3.2 mmHg, respectively (p = 0.007). Similar trends were also observed for peripheral pulse pressure (PP), aortic BP and aortic PP. In the age-adjusted multiple linear regression model, negative predictors of SBP, PP, aortic BP and aortic PP were the estimated glomerular filtration rate (eGFR), female sex and coffee consumption. Positive predictors included body mass index (BMI) and low-density lipoprotein cholesterol (LDL-C). Then, our findings show that regular coffee drinking is associated with lower SBP, PP, aortic BP and aortic PP, but with similar arterial stiffness.
