['Bone-derived circulating CD34-positive cells are reported to play an important role in vascular maintenance. Additionally, height might influence age-related hematopoietic bone marrow decline, as it positively correlates with total bone marrow volume. As hypertension should mask the beneficial effects of circulating CD34-positive cells, hypertension status should account for this correlation. The present study aimed to clarify the clinical importance of height on vascular maintenance in older Japanese men.', 'We carried out a cross-sectional study of 343 older men aged 65-69\u2009years who underwent a general health checkup from 2013 to 2015.', 'Independent of known cardiovascular risk factors, height was found to be slightly, but significantly, positively correlated with the log number of circulating CD34-positive cells in systolic, but not non-systolic, hypertensive men. Multilinear regression analysis showed a parameter estimate (B) and standardized parameter estimate (β) of 3.23\u2009×\u200910'] Is height an indicator of vascular maintenance capacity in older men?
