People who are 65 years of age or older and who have a higher than average caffeine intake are indicated to be a lower risk of coronary vascular disease and also heart mortality than those of the same age with a lower recorded intake. The reason is most likely to be due to the beneficial effect of caffeine on blood pressure. It was also found that the higher their intake, the more beneficial the results except for those who were overly hypertensive.

The same was not found to be true in people below age 65.
