Coffee linked with increased cardiovascular risk in young adults with mild hypertension

[font size=3]London, UK – 29 Aug 2015: Coffee drinking is associated with increased risk of cardiovascular events (mainly heart attacks) in young adults (18-45) with mild hypertension, according to research presented at ESC Congress today by Dr Lucio Mos, a cardiologist at Hospital of San Daniele del Friuli in Udine, Italy.1 The 12 year study in more than 1 200 patients found that heavy coffee drinkers had a four-fold increased risk while moderate drinkers tripled their risk. Future prediabetes attenuated the associations suggesting that the effect of coffee on cardiovascular events may be mediated by its long term influence on blood pressure and glucose metabolism.
“There is controversy surrounding the long term cardiovascular and metabolic effects of coffee consumption in patients with hypertension,” said Dr Mos. “Our study was designed to evaluate whether coffee drinking had an effect on the risk of cardiovascular events, and if the association was mediated by effects on blood pressure and glucose metabolism.”
The study included 1,201 non-diabetic patients aged 18 to 45 years from the prospective HARVEST study who had untreated stage 1 hypertension (systolic blood pressure between 140 and 159 mmHg and/or diastolic blood pressure between 90 and 99 mmHg). Coffee consumption was categorised by the number of caffeine-containing cups per day: non-drinkers (0), moderate (1–3) and heavy drinkers (4 or more). Among the participants, 26.3%were abstainers, 62.7% were moderate and 10.0% were heavy coffee drinkers. Coffee drinkers were older and had a higher body mass index than abstainers.
There was a linear relationship between coffee use and risk of hypertension needing treatment. The association reached statistical significance for heavy drinkers (figure 1). As type 2 diabetes often develops in hypertensive patients at a later stage, the study examined the long term effect of coffee drinking on the risk of developing prediabetes. A linear relationship was found, with a 100% (30% to 210%) increased risk of prediabetes in the heavy coffee drinkers (figure 2).
