Effect of Ramadan fasting on arterial stiffness parameters among Egyptian hypertensive patients with and without chronic kidney disease.

This study aims at evaluate of the effect of Ramadan fasting on AS parameters, augmentation index (AIx), and pulse wave velocity (PWV) in hypertensive patients with and without CKD. A cohort of 71 patients (mean age = 57.14 ± 14.5 years, 42 females and 29 males) were enrolled in this study; 34 with CKD and 37 without CKD. All patients had hypertension, while 25 patients had diabetes mellitus. Serum creatinine (Cr), serum urea, estimated glomerular filtration rate (eGFR) by CKD-EPI formula, brachial and central systolic blood pressure (BSP and CSP respectively), brachial and central diastolic blood pressure (BDP, CDP, respectively), AIx and PWV (measured by cuff based oscillometric method) were assessed before and after Ramadan fasting. In patients without CKD BSP, BDP, CSP, and CDP significantly decreased (P = 0.0001, 0.0001, 0.0001, and 0.0001, respectively). In patients with CKD BSP and CSP significantly decreased (P = 0.005 and 0.005), while BDP and CDP decreased, but the change was not statistically significant. AIx significantly decreased in patients without CKD (P = 0.0001, mean 36.24 before and 26.22 after Ramadan fasting), but did not significantly change in patients with CKD (P 0.381 mean 25.94 before and 25 after Ramadan fasting). PWV decreased in both groups, but the change was not significant. Serum Cr significantly increased (P = 0.03 mean 1.06 mg/dL before and 1.11 mg/dL after Ramadan fasting), while eGFR did not significantly decrease (P = 0.072, mean 69.73 mL...
