The Thrombolysis in Myocardial Infarction <unk>   is one of the most frequently used classifications in the cardiovascular trials. These<unk>  were developed during early<unk>  trials to define minor and major hemorrhagic episodes in patients of ST segment elevation MI (STEMI) treated with a fibrinolytic drug and have been there for 30 years. In the past the<unk>  depended mainly on laboratory values, such as a decrease in hemoglobin or hematocrit values. The<unk>  have been modified over time and the most recent version is shown below.
