Seniors Favorite Drink Coffee May Improve Blood Flow in Small Vessels

New study takes us one step closer to understanding how coffee might benefit cardiovascular health; previously linked to lower risk of dying from heart disease, stroke

Nov. 20, 2013 – The caffeine in a cup of coffee appears to improve your blood flow by helping your small blood vessels work better, according to research presented at the American Heart Association’s Scientific Sessions 2013.

The study adds to a growing body of research about coffee, the most widely consumed beverage worldwide.  Previous studies showed that drinking coffee is linked to lower risks of dying from heart disease and stroke, and that high doses of caffeine may improve the function of larger arteries.

This study of 27 healthy adults showed – for the first time – that drinking a cup of caffeinated coffee significantly improved blood flow in a finger, which is a measure of how well the inner lining of the body’s smaller blood vessels work.

Specifically, participants who drank a cup of caffeinated coffee had a 30 percent increase in blood flow over a 75-minute period compared to those who drank decaffeinated coffee.

“This gives us a clue about how coffee may help improve cardiovascular health,” said Masato Tsutsui, M.D., Ph.D., lead researcher and a cardiologist and professor in the pharmacology department at the University of the Ryukyus in Okinawa, Japan. The study was funded in part by the All Japan Coffee Association.

Study participants were people who did not regularly drink coffee, ranging in age from 22 to 30. On one day, each participant drank one five-ounce cup of either regular or decaffeinated coffee. Then researchers measured finger blood flow with laser Doppler flowmetry, a non-invasive technique for gauging blood circulation on a microscopic level.

Two days later, the experiment was repeated with the other type of coffee. Neither the researchers nor the participants knew when they were drinking caffeinated coffee.

The researchers noted blood pressure, heart rate, and vascular resistance levels. They also took blood samples to analyze levels of caffeine and to rule out the role of hormones on blood vessel function.

Compared to decaf, caffeinated coffee slightly raised participants’ blood pressure and improved vessel inner lining function. Heart rate levels were the same between the two groups.

It’s still unclear how caffeine actually works to improve small blood vessel function, although Tsutsui suggests that caffeine may help open blood vessels and reduce inflammation.

“If we know how the positive effects of coffee work, it could lead to a new treatment strategy for cardiovascular disease in the future,” said Tsutsui.

“Caffeine is in coffee, tea, soft drinks, chocolate and some nuts. Whether high caffeine intake increases the risk of coronary heart disease is still under study,” according to the American Heart Assocation.

“Many studies have been done to see if there's a direct link between caffeine, coffee drinking and coronary heart disease. The results are conflicting. This may be due to the way the studies were done and confounding dietary factors. However, moderate coffee drinking (1–2 cups per day) doesn't seem to be harmful.”
