Abstract

BACKGROUND: Patients with chronic kidney disease (CKD) are at an increased risk of atrial fibrillation (AF). There is a need for novel biomarkers to reliably and accurately predict AF in this population. High-sensitivity troponin (HsTP) allows the detection of low troponin concentrations. The utility of HsTP for evaluating the risk of AF in CKD has not been established.

OBJECTIVE: We sought to explore the association between HsTP and the risk of incident AF in CKD.

METHODS: The Chronic Renal Insufficiency Cohort is a prospective cohort of 3939 individuals with mild to moderate CKD. HsTP was measured at study enrollment. Patients with a history of AF were excluded. Patients were followed for new-onset AF, and the association between HsTP and incident AF was examined using the Cox regression model.

RESULTS: A total of 3217 participants were included. Over a median follow-up period of 7.1 years (interquartile range 5.0-8.4 years), 252 patients developed new-onset AF (12 events per 1000 person-years of follow-up). The incidence of new-onset AF was 2.46%, 7.06%, and 11.5% at 3, 6, and 9 years, respectively. Compared with the lowest quartile of HsTP, patients in the third quartile of HsTP (hazard ratio 2.40; 95% confidence interval 1.58-3.65; P < .001) and the fourth quartile of HsTP (hazard ratio 4.43; 95% confidence interval 2.98-6.59; P < .001) had a higher incidence of AF.

CONCLUSION: HsTP levels are associated with an increased risk of AF in patients with mild to moderate CKD. This association remains significant despite adjustment for traditional AF risk factors and chronic renal disease.
