An information-theoretic approach using momentary information transfer identified differences in cardiovascular causal couplings between healthy pregnant women and those with pre-eclampsia.
A novel information-theoretic approach can quantify causal couplings in cardiovascular systems, such as the interaction between heart rate and blood pressure in pre-eclampsia.
This article studies a recently introduced information-theoretic approach to detect and quantify the causal couplings in a complex cardiovascular system. In the first step a causal algorithm detects the coupling delays and in the second step the causal strength of each coupling mechanism is quantified using the recently introduced momentary information transfer. As an example, the method is applied to time series of respiration, systolic and diastolic blood pressure, and heart rate of pregnant healthy women and women suffering from pre-eclampsia. A possible explanation for the influence of heart rate on systolic blood pressure is found and some differences between healthy women and patients are discussed.
Runge et al. (Mon,) conducted a other in Pre-eclampsia. Momentary information transfer algorithm was evaluated on Causal strength of multivariate cardiovascular couplings. An information-theoretic approach using momentary information transfer identified differences in cardiovascular causal couplings between healthy pregnant women and those with pre-eclampsia.
