Abstract:
To quantitatively assess the effects of age, blood pressure, chronic arterial hypertension, and physical activity on sublingual microcirculation in ambulatory volunteers. Methods Sublingual microcirculation was assessed in 61 volunteers with or without chronic arterial hypertension. Results Volunteers with chronic arterial hypertension had lower TVD all vessels , and TVD small vessels and PVD small vessels than those without this condition (16.0 ± 1.4 vs. 17.2 ± 1.6 mm/mm 2 , p 〈 0.01, 15.1 ± 1.3 vs. 16.1 ± 1.7 mm/mm 2 , p 〈 0.04, and 15.1 ± 1.3 vs. 16.1 ± 1.7 mm/mm 2 , p 〈 0.04, respectively). Mean blood pressure correlated with TVD all vessels ( r = −0.34, p 〈 0.01), TVD small vessels ( r = −0.31, p 〈 0.02), and PVD small vessels ( r = −0.27, p 〈 0.04) but not with other microvascular variables. Age was not correlated with any microcirculatory variables. Physical activity correlated with TVD all vessels and RBCV small vessels ( r = 0.30, p 〈 0.02 and r = −0.47, p 〈 0.001, respectively). Chronic arterial hypertension was the only independent determinant of PVD small vessels . Conclusions Preexistent chronic arterial hypertension was associated with lower vascular densities. In contrast, age showed no effect on sublingual microcirculation.
