Title: The impact of chronic kidney disease on long-term prognosis after coronary artery bypass grafting


Chronic kidney disease (CKD) was risk factor for cardiovascular event. However, there were few reports about the impact of CKD on long-term outcomes after coronary artery bypass grafting (CABG). Therefore, the present study aims to investigate the impact of CKD on long-term outcomes in patients undergoing CABG. 2,187 patients were included, excluding those with a history of AF, pacemaker implantation, in-hospital death, prolonged hospitalization for more than 30 days, and no remote rhythm data. Primary endpoints were all-cause death, major adverse cardiovascular events (MACE), and late-onset atrial fibrillation (AF). Late-onset AF was defined as occurring after postoperative day 30. Preoperative eGFR greater than or equal to 90 was classified as no CKD group, 45 to 90 as mild-moderate CKD group, and less than 45 as moderate-severe CKD group for comparison. There are 104 in the no CKD group, 1675 in the mild-moderate CKD group, and 408 in moderate-severe CKD group. The mean age of no CKD group was 48 years, significantly younger than that of the other mild-moderate CKD group (68 years) and moderate-severe CKD group (68 years). As CKD grade worsens, hypertension, diabetes mellitus, peripheral arterial disease, history of cerebral infarction, and history of old myocardinal infarction increase. The moderate-severe CKD group includes 179 dialysis cases (43.9%). All cause-survival rate at 15-year was 93.3% in no CKD group, 64.3% in mild-moderate CKD group, and 28.6% in moderate-severe CKD group. Freedom from late-onset AF was 95.8%, 86.9%, and 68.4%, respectively. Freedom from MACE was 86.3%, 68.5%, and 46.7%, respectively. Moderate-severe CKD was independent risk factor of all-cause death and MACE (odds ratio 4.35, 95% CI 1.73-10.94, p value= 0.0018, and odds ratio 3.45, 95% CI 1.74-6.85, p value= 0.0004 ), however not of late-onset AF (odds ratio 2.69, 95% CI 0.60-12.1, p value= 0.20). Long-term prognosis after CABG worsens with worsening CKD grade. Moderate-severe CKD, in particular, was an independent risk factor for all-cause death and MACE.
