TYPES OF SYSTOLIC ARTERIAL BLOOD PRESSURE ORTHOSTATIC REACTIONS IN PATIENTS WITH ARTERIAL HYPERTENSION

Peculiarities of systolic arterial blood pressure (SABP) changes during the clino/orthotatic test in patients with primary arterial hypertension (AH). 154 patients were investigated, (58 males and 94 females), median age 63±7 years. Average duration of AH was 10,4?7,8 years. 48 patients had mild AH, 55 had moderate AH, 51 had severe AH. According to the changes of SABP during the orthostatic test patients were divided into 3 groups: increase of SABP ? group 1 (hypertonic type), no changes of SABP ? group 2 (isotonic type), decrease of SABP ? group 3 (hypotonic type). Minimal change on 5 mm was a criteria of SABP increase or decrease. During the transition from clinostasis to orthostasis 67,5% of patients had SABP increase, 11,7% of pa-tients had no changes of SABP and in 20,8% of patients SABP decreased. Hypertonic type of reaction was more frequent in males (81%), than in females (59,4%). Hypotonic and isotonic types were seen less frequent in males (in 12,1% and in 6,9% of patients respectively), than in fe-males (in 26% and in 14,6% of patients respectively). Variations in diastolic and systolic blood pressure parameters that were found during orthostatic tests indi-cate on the importance of conducting a separate comparative and descriptive investigation with using control group.
