Cardiac troponin T (CTNT) elevation occurs in 55.6% of patients after pacemaker implantation but is not linked to 1-year adverse outcomes. Gender, NT-pro-BNP, LVEF, eGFR, and fluoroscopy time predict CTNT elevation.

Area of Science:

  • Cardiology
  • Biomarkers
  • Medical Devices

Background:

  • Cardiac troponin T (CTNT) is a biomarker for myocardial injury.
  • Pacemaker implantation is a common procedure for cardiac rhythm management.
  • Understanding CTNT changes post-implantation is crucial for patient management.

Purpose of the Study:

  • To investigate the incidence, significance, and predictive factors of CTNT elevation following pacemaker implantation.
  • To assess the relationship between post-implantation CTNT levels and short-term cardiac complications and outcomes.

Main Methods:

  • A prospective study included 374 patients undergoing pacemaker implantation with normal baseline CTNT.
  • Serum CTNT levels were measured at baseline, 6 hours, and 24 hours post-procedure.
Keywords:

  • Logistic regression analysis identified independent predictors of CTNT elevation.

    • Main Results:

    • CTNT levels significantly increased post-implantation, with 55.6% of patients showing elevation at 6 hours.
    • Elevated CTNT was not associated with a higher incidence of complications or adverse cardiac outcomes within 1 year.
    • Independent predictors of CTNT elevation included gender, baseline NT-pro-BNP, LVEF, eGFR, and fluoroscopy time.

    Conclusions:

    • Pacemaker implantation frequently causes transient CTNT elevation, which is generally not associated with adverse cardiac events within one year.
    • Factors such as gender, baseline NT-pro-BNP, LVEF, eGFR, and fluoroscopy time are independent predictors of CTNT elevation.
    • These findings aid in interpreting CTNT levels in patients undergoing pacemaker procedures.
