Association of high-sensitivity troponin T and I with the severity of stable coronary artery disease in patients with chronic kidney disease

Cardiac troponin blood levels are frequently elevated in patients with impaired renal function. Their predictive value for the severity of stable coronary artery disease (CAD) remains unclear in these cases. Therefore, we aimed to evaluate the blood levels of high-sensitivity troponin T and I (hsTnT/I) and their association with the severity of stable CAD in patients with chronic kidney disease. Overall, 2209 patients with suspected stable CAD undergoing invasive coronary angiography were included in an ongoing prospective cohort study. We identified 595 patients with impaired renal function defined as an estimated glomerular filtration rate (eGFR)
