Abstract: Objective: To study the risk factors of post-stroke depression, and to analyze the predictive value of heart rate variability. Methods: The clinic data 120 patients with depression after stroke and 120 patients with stroke (no depression) were collected and analyzed in accordance with the random number table from the January 2014 to January 2016 in our hospital . They were divided into study group and control group retrospectively . The factors of the two groups were compared and 添加作者 the correlation between heart rate variability and depression after stroke were analysis. Results: The constituent ratios of male and female in the study group was higher than that in the control group (P<0.05). The proportion of education degree above junior high school, retirement, living alone, hypertension, coronary heart disease in the study group were higher than those in the control group (P<0.05). The heart rate variability indexes in the study group were lower than those in the control group, and there was significant difference (P<0.05). The correlation between indexes of heart rate variability and post-stroke depression is higher (P<0.05). The time 4-6d and 1-3d (30%, 22.5%) in the study group was the higher-incidence of post-stroke depression than other periods (P< 0.05). The proportion (35%) of lesion in the basal ganglia position in post stroke depression patients was higher than that in other lesion (P<0.05), and the proportion of cerebral infarction type (61.67%) was higher than that of intracerebral hemorrhage (15%) and other types (P<0.05). Conclusion the risk factors of post-stroke depression are female, low education level, retirement, loneliness, high blood pressure, coronary heart disease, basal ganglia lesion, cerebral infarction and low heart rate variability. In the prevention of depression in patients with stroke, effective prevention programs should be developed with high risk factors.
