Impaired coronary blood flow reserve in prehypertension and function
September 05, 2008
Despite the fact that prehypertension has been shown to be associated with atherosclerosis and target-organ damage, no studies evaluating coronary flow reserve (CFR) among prehypertensive patients have been done. We assessed CFR in normotensive subjects, in subjects with prehypertension, and in newly diagnosed and never-treated subjects with established hypertension. We found that CFR was decreased in prehypertensive subjects, although not as significantly as in subjects with hypertension.
