56 IC95% [2.27-18.92]; p = 0.001) and (3) a peak of troponin ratio elevated than normal levels of 150 (HR 4.12 IC95% [1.45-11.65]; p = 0.01). The prevalence of myocardial infarction in MINOCA was 4.9% in the absence of these three criteria, 3.4% with one of the criteria present, 34.5% with two criteria present and 71.4% with all three criteria. The negative predictive value for MI was 96% in the presence of at least two criteria. Our study shows that the absence of inflammatory response, a high troponin and the presence of angiographic coronary atheroma are independently correlated with a myocardial infarction underlying cause of MINOCA.Considering that transcatheter aortic valve replacement (TAVR) procedures have become less invasive, the duration for monitoring patient care after a successful TAVR can be reduced. CK666 Therefore, this study aimed to investigate the prognostic value of baseline echocardiographic parameters for non-delayed discharge in patients after TAVR. The study group included 154 consecutive patients (mean age 84.4 ± 4.5 years; and 101 women) who underwent a TAVR. Comprehensive echocardiograms including both side indices of myocardial performance (IMP) and blood tests were obtained prior to the TAVR procedure. The median post-TAVR length of stay was 6 days while the mode and first quartile were both 4 days. Receiver operating characteristic curve analysis showed that the optimum cut-off value of the left-sided IMP in patients with a normal left ventricular ejection fraction (LVEF, ≥ 50%) (n = 124) for non-delayed discharge (≤ 4 days) was 0.34 with an area under the curve (AUC) value of 0.71563 and p value of less then 0.0001, while the optimum cut-off value in patients with reduced LVEF ( less then 50%) (n = 30) was 0.47 with an AUC value of 0.77778 and p value of less then 0.0120. An adjusted analysis indicated the negative left-sided IMP results as the only predictor for non-delayed discharge (p less then 0.0001). Furthermore, the adjusted predictors for survival without early cardiovascular re-hospitalization within 6 months after TAVR were the positive left-sided IMP result, when the cut-off value of 0.52 was used, and the presence of elevated RAP of 8 to 15 mmHg. The early discharge policy should be carefully considered in high-risk populations, but the left-sided IMP may play a significant role in the pre-screening process. Positive end-expiratory pressure (PEEP) is used to optimize oxygenation by preventing alveolar collapse. However, PEEP can potentially decrease cardiac output through cardiopulmonary interactions. The effect of PEEP on cardiac output during cardiopulmonary resuscitation (CPR) is not known. This was a preclinical randomized, controlled, animal study conducted in an animal research facility on 25 Landrace-Yorkshire pigs. After inducing cardiac arrest, CPR was performed with LUCAS 3. During CPR, pigs were ventilated at a PEEP of 0, 5, 10, 15, 20 cmH O (randomly determined via lottery) for 9 min. Cardiac output, obtained via ultrasound dilution, and PaO were measured, and oxygen delivery calculated for each PEEP. A mixed-effects repeated-measures analysis of variance was used to compare the baseline value adjusted mean cardiac output, PaO , and oxygen delivery between PEEP groups. Least significant difference test was used to conduct pairwise comparisons between PEEP groups. To determine optimum PEEP, Gaussian mixture model was applied to the adjusted means of cardiac output and oxygen delivery. Increasing PEEP to 10 and higher resulted in significant declines in cardiac output. A PEEP of 15 and higher resulted in significant declines in oxygen delivery. As PEEP was increased from 0 to 20, PaO increased significantly. Gaussian mixture model identified the 0-5 PEEP group as providing optimal cardiac output and oxygen delivery, with PEEP of 5 providing the highest oxygen delivery. A PEEP of 0-5 resulted in the optima
