Can Coffee Increase Your Risk of Heart Attack and Stroke?

New Study Tends to Think So!

A one year study from the Department of Cardiology of Athens Medical School
suggests caffeine could exert a detrimental effect on aortic stiffness
increasing the risk of cardiovascular disease.

Aortic stiffness is an important prognosticator of cardiovascular disease

In a cross-sectional study of 228 healthy subjects - 141 men in their mid
40s and 87 women of the same age – the researchers tracked aortic stiffness
coffee consumption over a one year period.

Aortic stiffness was evaluated with carotid-femoral pulse wave velocity
(PWV). This is a classical measurement of aortic stiffness.

Coffee consumption was categorized as none, low (<200>450 mL/d). A total of 14 per cent of subjects
consumed no coffee. 32 per cent were categorized as low, 36 per cent as
moderate and 18 per cent as high coffee consumers.

Compared with the nonconsumption group, PWV was on average 13% higher

“We have shown that caffeine acutely increases aortic stiffness and wave
reflections,” report the researchers in the June 2005 issue of American
Journal of Clinical Nutrition, (Vol. 81, No. 6, 1307-1312).
