Scientists from Jiao Tong University in Xi’an found that drinking coffee in the presence of hypertension and other diseases increases the risk of calcium deposition in the walls of the abdominal aorta, and therefore the risk of stroke and heart attack. The research was published in the journal Nutrition, Metabolism and Cardiovascular Diseases.
The researchers used data from the 2013-2014 National Health and Nutrition Survey (NHANES), which included more than 2,500 people. The severity of abdominal aortic calcification was assessed using X-ray DXA. Previous studies have shown that an increase in the severity of abdominal aortic calcification is associated with an increased risk of stroke and heart attack.
No significant relationship was found between coffee consumption and the severity of abdominal aortic calcification. However, in the presence of hypertension, diabetes, and cardiovascular disease, people who consumed an average of 390 g or more of coffee per day had slightly higher Kauppila calcification scores.
Overall, individuals who consumed large amounts of coffee had a 50% increased risk of severe abdominal aortic calcification. The risk increased to 70% in the presence of arterial hypertension.
Coffee causes a sharp increase in blood pressure, a decrease in endothelial function and can cause sleep disturbance. As the authors point out, the beverage could therefore potentially disrupt cholesterol metabolism. However, the study showed only a correlation, not a causal relationship, and other factors may explain the difference between the groups.
