Objective: The aim of the study was to asses parameters of the nail bed capillary net of the hand in hypertensives and normotensives in age group 60–80 years. Materials and Methods: The study included 121 subjects with age from 60 to 80 years who were divided in 2 groups. Group I consisted of 36 apparently healthy normotensives (66.4 ± 5.8 years). Group II included 85 hypertensives (68.8 ± 6.0 years) who were not receiving antihypertensive and antiplatelet therapy. Computer capillaroscopy of nail bed and 24-hour blood pressure monitoring performed. The evaluation of the capillary bed of cuticle was performed on the fourth finger of right or left hand. The density of capillary network was evaluated in percentages as a ratio between the visible capillaries area and the total area of capillaroscope window, which was 1 mm2 at low extension (õ200) of computer capillaroscope. Pericapillary zone size was calculated in micrometers as average value of 6 measurements for three capillaries at low (õ200) and high (õ530) magnifications. We used Mann-Whitney test, the differences were significant at p < 0.05. Results: Main parameters of central hemodynamic in groups I and II: heart rate 65.8 ± 10 and 64.9 ± 9 /min (p > 0.05); systolic blood pressure 121.9 ± 11.7 mmHg and 137.5 ± 13.7 mmHg (p = 0.038); diastolic blood pressure 76.4 ± 8.0 mmHg and 78.6 ± 9.4 mmHg (p > 0.05); pulse blood pressure 45.0 ± 12.8 mmHg and 59.1 ± 11.9 mmHg (p = 0.007), respectively. The density of capillary network was 6.6% in group I and 6.9% in group II (p > 0.05). The size of pericapillary zone was 105.4 ± 28.8 micrometers in group I and 116.8 ± 27.1 micrometers in group II (p = 0.036). Conclusion: In hypertensives aged 60–80 years compared with normotensives of the same age the size of pericaillar zone of nail bed was significantly bigger due to interstitial hyperhydration of this area. Further detailed investigations are necessary in order to prove the clinical importance of these changes in old hypertensive patients with special attention to effects of diuretics and other antihypertensive drugs on microcirculation.
