Abstract
|
|
|
Objective : Using patterns of change in heart rate variability (HRV), we investigated the effects of stress exposure and type of anger expression on cardiovascular diseases.
Methods : Eighty-nine medical students were evaluated by STAXI-K, BDI, BAI, and measured HRV. According to the scores of anger expression questions in STAXI-K, objects are comparted to three groups. Each group is compared with others on the levels of depression, anxiety and HRV. Additionally objects are divided into two groups of functional anger expression group and dysfunctional anger expression group, and each group also divided into two groups, depending on the exposure of stressful situation or not. Members who took part in the stress exposure groups, they’ve got a serial arithmetic process for five minutes. We surveyed patterns of HRV in 4 each groups and estimated interactions between existence of stressful situation or type of anger expression and HRV.
Results : Irrespective of stress manipulation, the dysfunctional anger expression group showed a marked increase in the LF/HF ratio in comparison to the functional anger expression group. Also, under conditions of stress manipulation, the stress exposure group exhibited a relatively increased level of TP. It can’t be discriminated any correlations between stress manipulation and type of anger expression.
Conclusion : Both of them, exposure to the stressful situation and type of anger expression, have influence on cardiovascular diseases. By controlling anger and way of express that, it is possible to diminish the incidence of cardiovascular diseases.
