Heart rate variability and blood pressure are key physiological parameters for assessing and anticipating mortality risk in cardiovascular ICU patients.
May support HRV and blood pressure integration into cardiovascular ICU risk models; hypothesis-generating and requires prospective validation before practice change.
Recognition of mortality-related factors in intensive care units (ICUs) could increase the efficiency and effectiveness of these units; The purpose of this research is to investigate the recorded data of the patients admitted in ICU with clinical analysis, in order to find indices of mortality. The long-term goal of this study is to develop an algorithm that is able to anticipate the mortality risk of ICU patients. Extracted features included time and frequency domain analysis of ECG and some of the physiological variables. The results showed that heart rate variability (HRV) and blood pressure are the most important parameters in ICU mortality risk assessment and anticipation for cardiovascular patients.
