Relationship between Heart Rate Variability Indexes and Common Biochemical Markers in Normal and Hypertensive Third Trimester Pregnancy

Abstract: Including all the subjects in the analysis, we found that complexity indexes are positively related with hemoglobin concentration in the pathologic group and uric acid blood levels whereas low frequency (LF) was negatively correlated with uric acid and creatinine concentration as well as positively correlated with platelet levels. The LF was the only spectral region with significant correlation. Through an independent analysis of groups, only significant correlations were found in normal and preeclamptic group… Show more

“…In addition, our results also showed an association between hyperuricemia and less HRV parameters increase in patients without PAD. Previous studies had reported that hyperuricemia was associated with low HRV parameters [ 38 , 39 ]. Hyperuricemia is affected by risk factors linked to insulin resistance, such as obesity, dyslipidemia and hypertension [ 40 42 ].…”

“…Estes achados podem ser explicados, uma vez que o sistema nervoso autônomo atua constantemente para modular o funcionamento de vários sistemas orgânicos [5]. Assim, este sistema é o principal responsável pelo aumento da frequência cardíaca, que é mais elevada em mulheres no período gestacional a fim de suprir as alterações anatômicas e fisiológicas e garantir adequado aporte sanguíneo para o feto [1][2][3][16][17][18].…”

“…Durante a gestação, a volemia sanguínea, o dé-bito cardíaco e o volume sistólico aumentam, o que leva a uma sobrecarga cronotrópica para manter a homeostase [1][2][3]. Assim, para suprir a demanda de aporte sanguíneo para o feto, o sistema nervoso autônomo atua elevando a frequência cardíaca (FC).…”

“…In addition, hyperuricemia has been associated with various risk factors for renal failure [ 12 , 14 , 15 ]. Previous studies have reported an association between hyperuricemia and low HRV parameters in various populations [ 16 18 ]. However, few studies have evaluated the relationship between UA and changes in HRV before and after HD.…”
