Abstract:
Objective:To explore the relationship between non-dipper heart rate (HR)and severity of cerebral em- bolism from atrial fibrillation in aged patients.Methods:A total of 95 aged patients with persistent atrial fibrillation complicated cerebral embolism received 24h Holter monitoring within 24h after hospitalization.According to 24h Holter monitoring results,patients were divided into dipper HR group (n=21),non-dipper HR group (n=56) and reverse dipper HR group (n=18).United States national institutes of health stroke score (NIHSS)was used to evaluate neurological deficit severity of three groups,and the relationship between HR and NIHSS score was retro- spectively analyzed.Results:Compared with dipper HR group,there were significant rise in mean HR [(83.09± 8.06)beats/min vs.(89.09±7.83)beats/min vs.(95.50±8.06)beats/min]and NIHSS score [(5.14±2.65) scores vs.(7.95±5.30)scores vs.(11.11±7.41)scores]in non-dipper HR group and reverse dipper HR group, and those of reverse dipper HR group were significantly higher than those of non-dipper HR group,P<0.05 or<0.01.Conclusion:Abnormal circadian changes of heart rate can aggravate patient's condition in aged patients with atrial fibrillation complicated cerebral embolism.So based on routine treatment,regulation of circadian rhythm of heart rate should also be noticed.
