Prolonged Tachycardia with Higher Heart Rate Is Associated with Higher ICU and In-hospital Mortality.

Prolonged Tachycardia with Higher Heart Rate Is Associated with Higher ICU and In-hospital Mortality. Acta Med Okayama. 2019 Apr;73(2):147-153 Authors: Hayashi M, Taniguchi A, Kaku R, Fujimoto S, Isoyama S, Manabe S, Yoshida T, Suzuki S, Shimizu K, Morimatsu H, Momota R Abstract Tachycardia is common in intensive care units (ICUs). It is unknown whether tachycardia or prolonged tachycardia affects patient outcomes. We investigated the association between tachycardia and mortality in critically ill patients. This retrospective cohort study's primary outcome was patient mortality in the ICU and the hospital. We stratified the patients (n=476) by heart rate (HR) as LowHR, MediumHR, and HighHR groups. We also stratified them by their durations of HR >100 (prolonged HR; tachycardia): MildT, ModerateT, and SevereT groups. We determined the six groups' mortality. The ICU mortality rates of the LowHR, MediumHR, and HighHR groups were 1.0%, 1.5%, and 7.9%, respectively; significantly higher in the HighHR vs. LowHR group. The in-hospital mortality rates of these groups were 1%, 4.5%, and 14.6%, respectively; significantly higher in the HighHR vs. LowHR group. The ICU mortality rates of the MildT, ModerateT, and SevereT groups were 0.9%, 5.6%, and 57.1%, respectively. The mortality of the HRT=0 (i.e., all HR ≤ 100) patients was 0%. The in-hospital mortality rates of the MildT, ModerateT, and SevereT groups were 1.8%, 16.7%, and 85.7%, resp...
