While the standard practice guidelines recommend using the 0,1-hour (hr) and 0,3-hr hs-cTnT algorithms, their efficacy has been not clearly established in chronic kidney disease (CKD) patients. Purpose We aimed to assess the differential associations between the two algorithms mentioned above with significant coronary stenosis in CKD patients. Methods This was a retrospective cohort study. Patients aged ≥18 years (yr) who were diagnosed with NSTE-ACS and had undergone coronary angiogram were recruited. The differential association between significant coronary stenosis and being ruled in based on the 0,1-hr and 0,3-hr hs-cTnT algorithm in both CKD patients and those normal renal function was analyzed and reported. Results There were 158 and 160 patients in the CKD group and the normal renal function group, respectively. The prevalence of significant coronary stenosis was higher in the CKD group (70.4% vs. 57.8%, P =0.028). Among CKD patients, factors associated with significant coronary stenosis were hypertension (OR =2.68; 95%CI 1.10-6.50) and being ruled in by the 0,3-hr algorithm (OR =3.65; 95%CI 1.27-10.52). In the normal renal function group, age (OR =1.04; 95%CI 1.01-1.06), male sex (OR =2.15; 95%CI 1.09-4.22), and being ruled in by the 0,1-hr algorithm (OR =3.12; 95%CI 1.20-8.10) were associated with significant coronary stenosis. Conclusions Being ruled in according to the 0,3-hr algorithm was significantly associated with coronary stenosis in CKD patients, making this a likely algorithm of choice in these patients.
