In a double-blind, placebo-randomized study, nitrendipine reduced systolic blood pressure regardless of the presence or absence of arterial calcifications. The antihypertensive effects were significantly more pronounced in subjects with aortic calcium deposits in comparison with patients without clinical signs of arteriosclerosis (p < 0.01). Diastolic blood pressure was significantly reduced only in patients with aortic calcifications, and remained unchanged in subjects with noncalcified aorta. Aortic pulse wave velocity decreased significantly in patients with aortic calcifications (p < 0.001), but remained unaffected in patients with noncalcified vessels. Multivariate regression analysis showed that antihypertensive action of nitrendipine was correlated with the presence of aortic calcium deposits independently of age or baseline blood pressure levels. The results of the present study indicate that an overt arteriosclerosis as demonstrated by the presence of aortic calcifications on abdominal radiographs is a good indication for use of dihydropiridines in patients with ESRF.
