Key result
Migraine linked to higher resting pulse rate and lower HRV, indicating impaired cardiac vagal tone.
Why the study?
Migraine is associated with autonomic nervous system dysfunction characterized by reduced heart rate variability, but cardiac autonomic function in migraine patients requires assessment.
Does heart rate variability differ between newly diagnosed untreated migraine patients and healthy controls?
Case-Control (n=90)
No
Does heart rate variability differ between newly diagnosed untreated migraine patients and healthy controls?
Migraine is associated with autonomic dysfunction characterized by impaired cardiac vagal tone, as evidenced by reduced heart rate variability.
Supports autonomic screening in young migraine patients; leaves open causal links and cardiovascular risk prediction.
Background: Migraine is associated with autonomic nervous system dysfunction with reduced heart rate variability (HRV).Objective: To assess the cardiac autonomic function in migraine patients.Methods: This prospective study was carried out in the Department of Physiology, Bangabandhu Sheikh Mujib Medical University during 2013. Cardiac autonomic nerve function of 60 newly diagnosed untreated migraine patients aged 15-30 years, both male and female was assessed by analyzing time domain measures of HRV. Thirty age, sex, BMI matched healthy control were also assessed and compared. The diagnosed migraine patients were selected from the out patient department of Neurology, BSMMU, Dhaka. The HRV parameters were recorded by a 4 active channels, RMS polyrite-D. For statistical analysis, Independent Sample t-test was used.Results: Resting pulse rate, mean heart rate were found significantly higher and mean R-R interval, SDNN, RMSSD were significantly lower in all patients with migraine than those of healthy control.Conclusion: Autonomic dysfunction characterized by impaired cardiac vagal tone was associated with migraine.Bangladesh Soc Physiol. 2017, December; 12(2): 57-60

Akter et al. (2018) conducted a case-control in Migraine (n=90). Migraine vs. Healthy controls was evaluated on Time domain measures of heart rate variability (HRV). Migraine was associated with significantly higher resting pulse rate and lower heart rate variability (SDNN, RMSSD) compared to healthy controls, indicating impaired cardiac vagal tone.
