简要总结
This is a cross-sectional pilot study to assess coronary artery disease with minimal invasive techniques in patients with asymptomatic troponin elevation after noncardiac surgery. The primary objective is to quantify coronary artery disease, as determined by coronary CT and MR, as a cause of postoperative myocardial injury. The secondary objective is to correlate coronary calciumscore to postoperative levels of troponin.
