<prompt> Answer this question truthfullyWhat do intraprocedural thrombotic events mean?  <response>: <reason> The overall rate of IPTE is high, currently estimated by several studies to be between 3.5 and 11.4 of all PCI procedures. In 2012, McEntegart et al. performed frame-by-frame analysis for 3,428 patients with NSTEMInon-ST elevation acute coronary syndrome NSTEACS previously enrolled in the ACUITY trial Acute Catherterization and Urgent Intervention Triage Strategy. The total incidence of IPTE was 3.5 with varying rates of occurrence among specific etiologies of IPTE. 89.3 of all IPTE occurred at the level of a main branch. Similarly in 2012, Pride et al. evaluated 1,452 high-risk patients with NSTTEAS enrolled in the EARLY ACS trial Early Glycoprotein IIbIIIa in Non-ST-Segment Elevation Acute Coronary Syndrome who underwent angiographic assessment. Incidence of IPTE was 11.4. In contrast to McEntegart, the study by Pride et al. included high-risk patients only. High-risk criteria were defined by the authors as having at least two of the following: Ischemic changes on electrocardiography ECG, elevated cardiac enzyme, advanced age 60 years or age between 50-59 with documented coronary artery disease, cerebrovascular disease, or peripheral vascular disease. It is uncertain whether the inclusion criteria played a role in the increase of IPTE rates in the study as compared to McEntegarts findings.
