Introduction: Central pressure (CP) greater than the pressure measured on the arm, reflecting the blood flow in coronary, cerebral vascular and for this reason is a more significant predictor of cardiovascular complications in the future. The importance of the central contour analysis of the pulse wave is also in the fact that with this method, we can better understand the mechanisms of participation in the development of a variety of different types of hypertension including hidden and false system of its forms. Purpose Evaluation of the occurrence of various forms of arterial hypertension and prehypertension (AH/PH) in students based on the results of preventive examinations
Methods: 105 students (51 boys and 54 girls aged between 19 and up to 22 y.o.) were screened for risk factors (RF) - smoking, burdened heredity, overweight, poor diet, lack of exercise, low stress tolerance. Students were divided into two groups: 1g. - without RF; 2g. - with the RF. The parameters of CP were determined using diagnostic complex BPLab Vasotens ("Peter Telegin", Russia). It was valuate such marks as systolic BP aortic (SYSao), diastolic BP aortic (DIAao), index of augmentation in aorta (AIxao), pulse pressure amplification (PPA) and others. Based on the comparison of results of the peripheral and central pressure it was assessed the presence of h idden (isolated increasing of CP), false (isolated increasing of the pressure on the shoulder) and systemic (simultaneous increasing of CP and peripheral pressure) AH/PH. Data are processed by means of the software package of "Statistica 8.0".
Results: Only a third of the students did not have any risk factors. Among all surveyed students it was revealed systemic AH/PH in 18 (17,2%), hidden one 12 (11,4%) and false one 8 (7,6%). The remaining 67 persons (63,8%) were distinguished by the presence of stable normotension. Systemic AH/PH is almost ten times more common among people with RF. False AH/PH was detected with equal frequency in the two groups of observation - with and without presence of RF. Hidden AH/PH observed only among those with the presence of RF.
Conclusion: One in ten of the surveyed students distinguished by the presence of hidden AH/PH, which can not be detect using traditional measurement of peripheral pressure. Therefore in carrying out preventive examinations of young people should be more widely used estimate of CP for the early detection of hidden forms of high blood pressure. This approach will contribute to more effective formation of groups of cardiovascular risk among young population with the aim of more targeted correction of risk factors, including hypertension hidden
