Dysmenorrhea on blood pressure and radial pulse spectrum in women

We sought to investigate the influence of dysmenorrhea on blood pressure and radial pulse spectrum. The crosssectional study enrolled 221 women, each of whom received measurements of blood pressure and radial pulse wave. We used the Fourier series methods to calculated the first seven harmonic amplitudes of the radial pulse wave(C1∼C7). The results showed that the mean heart rate, diastolic blood pressure, and systolic blood pressure were higher in women with primary dysmenorrhea than in women without dysmenorrhea. Those with primary dysmenorrhea had lower C3, C4, C6, and C7, taking those without dysmenorrhea as reference. Multiple linear regression analysis showed that primary dysmenorrhea was independently associated with diastolic blood pressure, systolic blood pressure, C3 and C4.
