Abstract:
In East Asian countries, patients with chronic kidney disease (CKD) have lower cardiovascular risk profiles and experience fewer cardiovascular events (CVEs) than those in Western countries. Thus the clinical predictive performance of well-known risk factors warrants further testing in this population. Methods The KoreaN cohort study for Outcome in patients With Chronic Kidney Disease (KNOW-CKD) is a multicenter, prospective observational study. We included 1579 participants with CKD G1–G5 without kidney replacement therapy between 2011 and 2016. The main predictor was the coronary artery calcium score (CACS). The primary outcome was a composite of nonfatal CVEs or all-cause mortality. Secondary outcomes included 3-point major adverse cardiovascular events (MACEs; the composite of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke), all CVEs and all-cause mortality. Results During a median follow-up of 5.1 years, a total of 123 primary outcome events occurred (incidence rate 1.6/100 person-years). In the multivariable Cox model, a 1-standard deviation log increase in the CACS was associated with a 1.67-fold [95% confidence interval (CI), 1.37–2.04] higher risk of the primary outcome. Compared with a CACS of 0, the hazard ratio associated with a CACS & gt;400 was 4.89 (95% CI 2.68–8.93) for the primary outcome. This association was consistent for secondary outcomes. Moreover, inclusion of the CACS led to modest improvements in prediction indices of the primary outcome compared with well-known conventional risk factors. Conclusions In Korean patients with CKD, the CACS was independently associated with adverse cardiovascular outcomes and all-cause death. The CACS also showed modest improvements in prediction performance over conventional cardiovascular risk factors.
