Chart 3 - Description of Results Author Year Results Conclusions Ablonskyt ė - D ū donien ė et al. 5 2012 Due to ICG, it was possible to offer an integrated analysis with electrocardiogram to help identify the patients at risk of serious adverse events after ST-segment. All-cause or cardiac mortality and in-hospital recurrent ischemia, recurrent nonfatal MI, and need for revascularization were considered as serious adverse events. A greater risk of cardiac death was observed within a 5-year period after STEMI. A greater risk of cardiac death was observed within a 5-year period after STEMI. An integrated analysis of electrocardiogram and impedance cardiogram helps estimate patient's risk of adverse outcomes after STEMI. Braždžionyt ė and Macas 11 2006 Hemodynamic evaluation in patients with acute myocardial infarction (AMI) is crucial. The management of the intra-aortic balloon (IAB) in patients with cardiogenic shock can be made by the invasive Swan-Ganz method. However, noninvasive methods, such as impedance cardiography (ICG), can also have a place in monitoring these patients. The study aimed to evaluate the possibility of applying a noninvasive method in the hemodynamic monitoring during AMI complicated by cardiogenic shock, managed by an intra-aortic balloon. A total of 16 patients were selected; anterior AMI was diagnosed in 68.75% of them, inferior in 25% and circular in 6.25%. Primary angioplasty was successfully performed in 43.75% of the patients; unsuccessfully, in 1 patient, who died within the first 18 hours. Half of patients underwent cardiac surgery within the first two weeks. Mortality rate was 68%. A total of 109 paired measurements were carried out in 16 patients in accordance with different IABP stages. Monitoring of cardiac output, cardiac index, systemic vascular resistance and systolic volume were compared by the two methods, every 12 hours. Significant correlation of cardiac output values was observed between the impedance cardiography and the Swan- Ganz technique during intra-aortic balloon use. Noninvasive evaluation of hemodynamic indices by continuous monitoring of impedance cardiography during acute myocardial infarction complicated by cardiogenic shock and managed by an intra-aortic balloon is a reliable method for further application. Fuller 12 2006 The study examined the use of impedance cardiography to stimulate cardiac output in critically ill patients in the intensive care unit. Cardiac output was measured, concurrently, in 61 patients with a pulmonary artery catheter (PAC) and impedance cardiography (ICG). The study has found a low correlation between PAC and ICG in critically ill patients, with 95% confidence interval, but the exclusion of patients with valve regurgitation and adjustment for hematocrit and skinfold thickness improved agreement. The support of clinicians for the introduction of any new technology is as important as the accuracy and reliability of that technology. Only with such support can impedance cardiography be accepted. The use of bioimpedance led to a 71% reduction in PAC usage in critically ill patients. Keuhne et al. 13 2013 Fifteen postinfarction patients, with symptomatic heart failure and akinetic or dyskinetic segment were included in the study. During the implantation of a cardiac resynchronization therapy (CRT) device, stroke volume was measured via impedance cardiography. It has shown an advantage over the pulmonary artery catheter because it is a simple method for measuring daily hemodynamic data of patients. Impedance cardiography is a valid parameter to estimate stroke volume and to guide optimization of CRT timing in postinfarction patients. Silva et al.
