Abstract

Highlight: Incidence of cardiovascular events was more frequent in low estimated glomerular filtration rate (eGFR) than high eGFR group. A large decline in eGFR was more observed in high eGFR than low eGFR group. A large decline in eGFR was at a 2-fold risk of cardiovascular events. Abstract: Background: It has been reported that a large decline in estimated glomerular filtration rate (eGFR) over time is associated with increased incidence of cardiovascular disease. We investigated whether this association differs according to the baseline eGFR. Methods: A total of 4666 patients (male 71%) with measurements of eGFR at both baseline and 1 year and that had no cardiovascular events at 1-year follow-up were retrieved from the Shinken Database between June 2004 and March 2015. The study population was divided into three groups by baseline eGFR (mL/min/1.73 m 2 ): high (≥60, n = 1650), intermediate (45–59, n = 1947), and low (<45, n = 1069) eGFR groups. Each eGFR group was further divided into two groups by eGFR slope (change at 1 year, <-10 and ≥-10 mL/min/1.73 m 2 ). The patient characteristics and the incidences of cardiovascular events within 3 years (after 1-year follow-up) were compared between the negatively large eGFR slope (<-10) and others (≥-10) in each eGFR group. Results: A total of 187 cardiovascular events occurred during the mean follow-up of 2.8 ± 0.6 years. The adjusted hazard ratios of eGFR slope (<-10 with reference to ≥-10) were 2.37 (95% CI, 1.28–4.40), 3.10 (95% CI, 1.78–5.40), and 2.66 (95% CI, 1.15–6.13) in the high, middle, and low eGFR groups, respectively. Similar results were found in patients with structural heart disease, but not in those without. Conclusions: Decline in eGFR was associated with an increase in cardiovascular events, and this effect was consistent regardless of the baseline eGFR.
