[Clinical and genetic associations in patients with non-cardioembolic ischemic stroke].

Objective: To study the associations of genetic markers influencing the residual reactivity of platelets during antiplatelet therapy with acetylsalicylic acid, and clinical and laboratory parameters, including parameters of the platelet hemostasis, in patients with non-cardioembolic ischemic stroke (IS) for a deeper understanding of the pathogenetic mechanisms and prediction of response to therapy and clinical outcome.

Material And Methods: The study included 296 patients (average age 64.65 [55; 76] years) undergoing treatment at the City Clinical Hospital named after.

Genetic Association Study and Machine Learning to Investigate Differences in Platelet Reactivity in Patients with Acute Ischemic Stroke Treated with Aspirin.

Aspirin resistance (AR) is a pressing problem in current ischemic stroke care. Although the role of genetic variations is widely considered, the data still remain controversial. Our aim was to investigate the contribution of genetic features to laboratory AR measured through platelet aggregation with arachidonic acid (AA) and adenosine diphosphate (ADP) in ischemic stroke patients.

[Dynamics of platelet hemostasis indices in patients with cardioembolic stroke against the background of atrial fibrillation].

Objective: To study the parameters of platelet hemostasis in patients with cardioembolic ischemic stroke on the background of atrial fibrillation and taking warfarin to assess the effectiveness of antiplatelet drugs in the prevention of recurrent ischemic strokes.

Material And Methods: 93 patients with ischemic stroke on the background of atrial fibrillation were examined, of which the main group consisted of 43 patients who took warfarin and 50 patients from the reference group without warfarin. The study of the platelet link of hemostasis using inductors (adrenaline, ristomycin, arachidonic acid, collagen, ADP) in patients of both groups was carried out.

[A clinical and genetic analysis of risk factors for the development of acute and chronic cerebral ischemia].

To study the association between polymorphic markers in the ACE, SERPINE1, FGB, F5, F7, F12, GP1BA, GPIIIa, MTHFR, CYP11B2, PON1, PON2, NOS2, NOS2, HIFla, LTA, ALOX5AP genes and clinical characteristics of acute and chronic forms of circulatory disorders of the brain. MATERIAL AND METHODS: The analysis of polymorphic variants in ACE, FGB, F5, F7, F12, GP1BA, GPIIIa, SERPINE1, MTHFR, CYP11B2, PON1, PON2, NOS2, NOS3, PDE4D, HIF1a, LTA, ALOX5AP in 81 patients with chronic cerebral ischemia (CCI) and 69 patients with ischemic stroke (IS), and their interrelation with clinical manifestations of disease were investigated. RESULTS AND CONCLUSION: The association between the T/T genotype of the PDE4D SNP 83C>T polymorphism and a rapid progression of hypertensive disease (GB) was revealed (OR=6.

[The state of microcirculation and platelet hemostasis in patients with ischemic stroke after systemic thrombolytic therapy].

Aim: The state of microcirculation and platelet hemostasis in patients with ischemic stroke after systemic thrombolytic therapy.

Material And Methods: Forty-two patients after systemic thrombolytic therapy (TLT) (mean age 64.26 [60.
