Official Title: Sonolysis in Risk Reduction of Symptomatic and Silent Brain Infarctions During Coronary Stenting Due to Ultrasound Activation of Endogenous Fibrinolytic System Using Trans
Brief Summary:
The aim of the project is to demonstrate a fibrinolytic effect of sonothrombolysis (continual transcranial Doppler monitoring) using 2 MHz diagnostic probe on the reduction of risk of brain infarctions due to the activation of endogenous fibrinolytic system during angioplasty and stenting of coronary arteries. 120 patients indicated for coronary angioplasty and stenting will be enrolled into the study in order to demonstrate a twenty-percent risk reduction of number and volume of brain infarctions detected using MRI examination 24 hours after cardiac endovascular treatment in 5% level of significance. Patients will be randomized - subgroup 1 will undergo a 40-240 minute non-diagnostic TCD monitoring during endovascular procedure, subgroup 2 will undergo interventions without TCD monitoring.
Confirmation of our hypothesis that sonothrombolysis is able to activate endogenous fibrinolytic system during coronary angioplasty and stenting with consecutive reduction of the number and volume of brain infarcts, can lead to the increase of the safety these patients. We can presume that up to 50% of patients indicated for endovasular heart treatment can be treated using these methods in the future.
