Study shows how coffee may improve cardiac health

USA Today reports that coffee may do more than wake you up. It may help your small blood vessels work better, at least according to new study.Research presented at an American Heart Association meeting in Dallas suggested that coffee “may help your small blood vessels work better,” although “the precise mechanism for this benefit is unknown,” according to study author Masato Tsutsui, a cardiologist and professor in the pharmacology department at the University of the Ryukyus in Okinawa, Japan.

HealthDay reports the new study “suggests that the caffeine in a cup of coffee might help your small blood vessels work better, which could ease strain on the heart.”

The Los Angeles Times reports that in a statement, Tsutsui said, “This gives us a clue about how coffee may help improve cardiovascular health.” He went on to say, “If scientists can figure out how caffeinated coffee helps small blood vessels work better, “it could lead to a new treatment strategy for cardiovascular disease in the future.”

These findings were presented at a medical conference. They should be considered preliminary as they have not yet undergone the “peer review” process, in which outside experts scrutinize the data prior to publication in a medical journal.
