For adults with severe hypertension, high coffee consumption is associated with an increased risk for CVD mortality, according to a study published in the Journal of the American Heart Association. Hiroyasu Iso, MD, PhD, MPH, and colleagues examined
the impact of coffee and green tea consumption on CVD mortality among 18,609 adults. Participants were classified into four BP categories: optimal and normal, high-normal, grade 1 hypertension, and grade 2-3 hypertension. The researchers documented 842 CVD deaths (median follow-up, 18.9 years). Among people with grade 2-3 hypertension, coffee consumption was associated with
an increased risk for CVD mortality, with HRs of 0.98 for less than one cup/day; 0.74 for one cup/ day; and 2.05 for two or more cups/day compared with non-drinkers. These associations were not seen among participants with optimal and normal BP, high-normal BP, or grade 1 hypertension. No association with increased CVD risk was seen for green tea consumption. “These findings may support the assertion that people with severe high [BP] should avoid drinking excessive coffee,” a coauthor said in a statement.
