Summary

The overall purpose of this study is to evaluate how effective Thromboelastography (TEG) is on identifying ischemic and hemorrhagic stroke patients at increased risk for bleeding after receiving tissue plasminogen activator (tPA), as well as on differentiating between patients in whom optimal thrombolysis has been achieved, and those whom it has not.

Thromboelastography

TEG (Thrombelastography) measurements include: Split Point (SP) is the time elapsed for the clot to initially form fibrin when the blood is first placed in the TEG machine. Reaction Time (R) is the time elapsed from its initial fibrin formation until the clot reaches 2mm. K is the time measured from R until the level of clot firmness reaches 20mm, measuring the speed of clot strengthening. These are measured in minutes. Delta measures if the formation of the clot has been suppressed; measured as the difference between R and SP. Angle reflects the speed at which clots form by forming the slope of the TEG tracing at R from the horizontal line. Maximum Amplitude (MA) in mm is the measure of maximum strength of the clot, true platelet function. G is the measure of the clot firmness; measured by a formula (G=(5000\*MA)/(100-MA) in dynes/cm2). LY30 is a measure of clot lysis at 30 minutes after MA is reached.
