Data are mean ± SD. value for comparison of groups (ANOVA). ∗Different from HS, . Different from CKD, . BP: blood pressure; eGFR: estimated glomerular filtration ratio; HDL: high-density lipoprotein; LDL: low-density lipoprotein; LVEF: left ventricular ejection fraction; LVEDD: left ventricular end-diastolic diameter; RAP: right atrial pressure; RER: respiratory exchange ratio; VO2peak: peak oxygen uptake; VO2 at AT: oxygen uptake at anaerobic threshold; VO2peak: VO2peak half-time; ACE: angiotensin converting enzyme; ARB: angiotensin receptor blocker.
