研究概览

简要总结

The purpose of this research study is to test if a commonly used, FDA-approved medication, called metoprolol, given at the conclusion of anesthesia following surgery, and during postoperative admission, reduces the possibility of heart related complications in patients with coronary artery disease (CAD).

详细描述

All enrolled patients will be beta-blocker naïve for at least 30-days prior to their scheduled surgical procedure. Study patients will be randomly assigned to an interventional drug arm (metoprolol tartrate vs placebo-comparator). At the conclusion of anesthesia following the surgical procedure, patients hemodynamically stable and meeting study safety parameters (heart rate greater-than-65; systolic blood pressure greater-than-110) will receive 3-intravenous doses of interventional study drug (metoprolol tartrate 5mg or placebo-comparator), based on previously assigned study arm; then, patients remaining hemodynamically stable will receive an oral dose (25mg metoprolol vs placebo-comparator) approximately every 8-hours for up to 3-days during postoperative hospital admission.

From arrival in the preop holding area through up to 72 hours postoperative admission to hospital discharge or end of study treatment (whichever occurs first), patients will be continuously monitored through medical records assessments, Holter monitoring, mobile hemodynamic monitoring (VisiMobile), and in-person daily follow-up visits that include 12-lead ECG, and blood collections for serial cardiac biomarkers for high-sensitivity troponin.

Additional study patient postoperative assessment will be performed at 30 days and 1 year after surgery. These can be completed by interview and/or medical record review.

干预措施: Placebo (Drug)

结局指标

主要结局

Effectiveness of Beta-blocker Therapy Reducing Post-operative Myocardial Injury

时间窗: 0-3 days, following surgery

Measured effectiveness of post-operative beta-blocker therapy to reduce myocardial injury by monitoring daily biomarkers (High-Sensitivity cardiac Troponin \[HS-cTn\]). Daily post-operative biomarker (hs-cTn) measurements to determine myocardial injury. Myocardial injury is defined as a new hscTn elevation \>99th percentile, or a 50% increase if the baseline hscTn is already elevated \>99th percentile

次要结局

  • Effectiveness in Reduction of Major Adverse Cardiac Events (MACE)(0-3 days, following surgery)
  • Monitor Post-operative Myocardial Ischemia(0-3 days, following surgery)
  • Number of Stroke Related Events Following Surgery(0-3 days, following surgery)
  • Number of Participants Having Vasopressor Therapy to Regulate Symptomatic Hypotension(0-3 days, following surgery)
  • Number of Participant Incidence of Clinically Relevant Bradycardia(0-3 days, following surgery)
  • Participants Number of Days Spent Post-operative Hospitalization(0-3 days following surgery)
  • Patient Recovery Progress Events at 30-days Post-operative.(30-days from surgery)
  • Participant Post-operative Mortality at 1-year Following Surgery(1-Year from surgery)
