Key result
Ramadan intermittent fasting did not significantly alter heart rate or heart rate variability measures compared to two months post-Ramadan among maintenance hemodialysis patients (P>0.05).
Why the study?
Limited data exist on the effect of Ramadan fasting on heart rate variability, a measure of cardiac autonomic function, among maintenance hemodialysis patients.
Does Ramadan intermittent fasting affect short-term heart rate variability in maintenance hemodialysis patients?
Observational (n=47)
Does Ramadan intermittent fasting affect short-term heart rate variability in maintenance hemodialysis patients?
p-value: p=>0.05
Ramadan intermittent fasting does not significantly alter short-term heart rate variability in maintenance hemodialysis patients, suggesting it does not impose substantial risk to cardiac autonomic function.
No takes yet. Share an insight, caveat, or question.
Ramadan fasting showed no HRV change in HD patients; leaves open need for larger trials before clinical adoption.
Abdulaziz et al. (2025) conducted an observational in maintenance hemodialysis (n=47). Ramadan intermittent fasting vs. Two months after Ramadan (within-subject comparison) was evaluated on Heart rate, frequency, and time domain measures of heart rate variability (p=>0.05). Ramadan intermittent fasting did not significantly alter heart rate or heart rate variability measures compared to two months post-Ramadan among maintenance hemodialysis patients (P>0.05).
