Two- Dimensional Speckle Tracking Echocardiography After Primary Percutaneous Coronary Intervention

Overview

ST-segment elevation myocardial infarction (STEMI) is a major cause of morbidity and mortality worldwide. In spite of decrease in acute and long-term mortality following STEMI in parallel with more use of reperfusion therapy, such as primary percutaneous coronary intervention (PPCI), modern antithrombotic therapy, and secondary prevention, mortality remains considerable. Reduced EF is a well-known predictor of increased short and long term major adverse cardiovascular events MACE :( heart failure, stroke and death)

Full Title of Study: “The Role of Two- Dimensional Speckle Tracking Echocardiography in Prediction of Remodeling and Major Adverse Cardiovascular Events in ST Elevation Myocardial Infarction After Primary Percutaneous Coronary Intervention”

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Prospective
  • Study Primary Completion Date: September 2021

Interventions

  • Procedure: 2D speckle tracking echocardiography
    • Global and segmental strain and strain rate in longitudinal and circumferential directions will be detected after PPCI; before discharge. The LV circumferential strains and strain rates will be determined from the short-axis views at the basal, middle, and apical levels, and longitudinal strains and strain rates will be determined from the apical 2-, 3-, and 4-chamber views of the LV. Segmental longitudinal strains equal to -15% or closer to 0 will be considered abnormal (injured segments). The average segmental longitudinal strain and strain rate of the abnormal segments is defined as the injury longitudinal strain (InjLS) and injury longitudinal systolic strain rate (InjLSRs).
