Kim GS, et al. - In this retrospective cohort study, researchers examined the link between inter-arm systolic blood pressure (SBP) difference (IASBPD) and incident chronic kidney disease (CKD) in 8,780 Korean adults without baseline CKD. At the first visit, bilateral blood pressure was evaluated—sequentially and repeatedly. A BP of ≥ 15 mmHg was considered to be IASBPD, according to government standard guidelines. An estimated glomerular filtration rate of < 60 mL/min/1.73 m² was defined as CKD. They evaluated IASBPD as a predictor of the incidence of CKD. Cardiovascular disease, including coronary heart disease and stroke, were also investigated. They reported the occurrence of incident CKD in 96 of 581 (16.5%) patients in the IASBPD group and in 1,037 of 8,199 (12.6%) patients in the non-IASBPD group during a mean follow-up period of 8.5 years. Findings revealed that incident CKD in the general population was independently predicted by increased IASBPD.
