Nailfold videocapillaroscopy is a noninvasive imaging technique used to examine the microvasculature. In this study we aim to investigate the capillaroscopic abnormalities of asymptomatic chronic smokers (N = 30), and compare findings to those of healthy nonsmokers (N = 30). Nailfold videocapillaroscopy was performed with a videodermatoscope, with images recorded at 40 x magnification. Capillary morphologies were assessed as normal, enlargement, tortuosity, and microhemorrhages. Capillaroscopic abnormalities were seen in 16 (53.3%) of subjects within the smoker group and seven (23.3%) within the nonsmoker group (p < 0.05). Six smokers had only capillary enlargement; another 10 had both capillary enlargement and microhemorrhages. In comparison, enlarged capillaries and both enlarged capillaries and microhemorrhages were observed in three and four nonsmokers, respectively. In conclusion, nailfold capillaroscopic abnormalities were more common among asymptomatic chronic smokers than healthy nonsmokers, with the enlargement of nailfold capillaries being the most common abnormality. Nailfold videocapillaroscopic examination may serve as an efficient tool in determining micro vascular abnormalities in asymptomatic chronic smokers not only for risk stratification purposes, but also to take the measures needed to preclude future vascular events. |
