Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults having coronary bypass surgery alone. It studies whether a heart blood test (hs-cTn) relates to early bypass graft blockage seen on a CT scan.

Age
18 years or older
Sex
All sexes can join
Disease stage
People having isolated coronary bypass surgery (no other procedure at the same time)
Biomarker or test result
hs-cTn level is measured as a heart biomarker; a CT scan of the heart (CCT) before discharge is needed

Main reasons for not taking part

  • No informed consent
  • Needing another procedure at the same time as the bypass
  • Known allergy to iodine-containing contrast agents
  • Kidney function problems (serum creatinine >140 mmol/l or GFR <30 ml/min/1.73 m2)
  • Pregnancy

Who can take part

  • patients with isolated coronary bypass surgery

Who cannot take part

  • Patients requiring a concomitant procedure
  • Patients that didn't undergo a CCT prior to discharge
  • Patients with known allergy to iodine-containing contrast agents
  • Unstable clinical state or severe heart failure
  • Renal function impairment (serum creatinine >140 mmol/l; estimated glomerular filtration rate (GFR) <30 ml/min/1.73 m2)
  • Patients withholding or lacking informed consent
  • Exclusion criteria concerning the CCT scan
  • Pregnancy
  • Patients with registered MI and registered bypass occlusion in coronary angiogram

About the trial

What the trial wants to find out

This study is to evaluate the correlation between hs-cTn level as cardiac biomarker for ischemia and early graft occlusion as assessed by CCT in patients undergoing coronary bypass surgery.
