Indices of coagulation hemostasis in patients with hemorrhagic stroke, associated with essential hypertension, after an early recovery period

Abstract

Objective: To determine and evaluate indices of coagulation hemostasis in patients with hemorrhagic stroke (HS), associated with essential hypertension (EH), after the early recovery period.Materials and methods. There were formed 2 groups of patients: the basic group included 94 patients (50 women and 44 men, middle age 54.4 ± 8.8 years old) who experienced HS, associated with EH, 6 months and earlier and had no spontaneous normalization of blood pressure over this period; the comparison group consisted of 104 persons (54 women and 50 men, middle age 53.7 ± 8.9 years old) with EH. They were matched groups by the key indicators. All the above-mentioned patients underwent fasted test of venous blood for detecting coagulation indices.Results. Determining the mean values of the coagulation parameters in both groups, there was found that the activated partial thromboplastin time (APTT) in the basic group was greater than in the comparison group — 28.345 ± 3.317 s and 26.629 ± 4.601 s, respectively (p<0.05). The patients of the basic group within 6-11 months after HS onset experienced a higher level of APTT (29.410 ± 3.806 s); and the value of thrombin time (TT) was lower than in the comparison group — 21.740 ± 1.691 s and 23.217 ± 5.740, respectively (p <0.05). In the basic group, Claus fibrinogen test showed a direct noticeable correlation (0.502) according to the Chaddock scale with the number of months after the early recovery period after HS.Conclusions. Hypertensive patients experienced HS have significantly higher value of APTT, indicating that the cascade of hemostasis is slowed down compared with patients with EH without complications. Hypertensive patients experienced HS 6–11 months before have statistically significant greater value of the APTT and lower TT value. In hypertensive patients after HS, there is a direct noticeable correlation between the concentration of Claus fibrinogen in the blood plasma and the number of months after the early recovery period after HS onset.
