Gum disease linked with higher risk of hypertension

People with gum disease (periodontitis) have a greater likelihood of high blood pressure (hypertension), according to a new UCL-led study. The meta-analysis of previous findings was published today in  Cardiovascular Research , a journal of the European Society of Cardiology. "We observed a linear association - the more severe periodontitis is, the higher the probability of hypertension," said senior author Professor Francesco D'Aiuto (UCL Eastman Dental Institute). "The findings suggest that patients with gum disease should be informed of their risk and given advice on lifestyle changes to prevent high blood pressure such as exercise and a healthy diet." High blood pressure affects 30-45% of adults and is the leading global cause of premature death, while periodontitis affects more than 50% of the world's population. Hypertension is the main preventable cause of cardiovascular disease, and periodontitis has been linked with increased risk of heart attack and stroke. "Hypertension could be the driver of heart attack and stroke in patients with periodontitis. Previous research suggests a connection between periodontitis and hypertension and that dental treatment might improve blood pressure, but to date the findings are inconclusive," said Professor D'Aiuto.
