Heart rate and arterial blood pressure correlation with Iranian traditional medicine temperamental model

Background: Although the temperament is one of the most important bases of the traditional medicine, it is always a challenging issue among the Hakims and philosophers. The present study aimed to determine the importance and validity of hemodynamic values in individual temperament.Method: This cross-sectional study has been carried out on ۲۰-۲۵ years old students of Tehran University of Medical Sciences. Individual temperament was initially determined using a questionnaire in which qualitative criteria of temperament have been changed to quantitative scales and presented as temperament score. Then temperament correlation with arterial blood pressure, pulse pressure and heart rate was evaluated using correlation and multivariate linear regression tests.Results: A hundred and two students (۴۵.۱% male) were enrolled. Multivariate linear regression adjusted for body mass index showed systolic blood pressure (β=۰.۹۵; t=۹.۷; p<۰.۰۰۱), diastolic blood pressure (β=۰.۹۹; t=۸.۲۶; p<۰.۰۰۱) and heart rate (β=۰.۸۸; t=۶.۲; p<۰.۰۰۱) were associated with temperament. In addition, temperament score was significantly higher in males (β=۵.۸۵; t=۲.۵; p<۰.۰۱۵) than females.Conclusion: To the best of our knowledge, this study is the first one that evaluated the correlation of hemodynamic factors with temperament model of Persian traditional medicine. Our findings showed that gender, high systolic and diastolic blood pressure and fast heart rate were associated with temperament.
