Effectiveness of pulmonary artery catheter monitoring for patients with cardiogenic shock of various causes: a systematic review and meta-analysis.

ABSTRACT:

Background

Cardiogenic shock is associated with significant morbidity and mortality. Invasive hemodynamic monitoring with pulmonary artery catheterization (PAC) can be useful in the assessment of changes in cardiac function and hemodynamic status; however, the benefits of PAC in the management of cardiogenic shock are not known well.

Methods

We performed a systematic review and meta-analysis of observational studies and randomized controlled trials, comparing in-hospital mortality between PAC and non-PAC groups of cardiogenic shock patients with various underlying causes. Articles were obtained from MEDLINE, Embase, and Cochrane CENTRAL. We reviewed titles, abstracts, and full articles and evaluated the quality of evidence using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) framework. We used a random-effects model to compare studies in terms of in-hospital mortality findings.

Results

We included twelve articles in our meta-analysis. Mortality among patients with cardiogenic shock was not significantly different between the PAC and the non-PAC groups [risk ratio (RR) 0.86, 95% confidence interval (CI): 0.73-1.02, I²=100%, P<0.01]. Two studies investigating cardiogenic shock caused by acute decompensated heart failure determined lower in-hospital mortality in the PAC group than in the non-PAC group (RR 0.49, 95% CI: 0.28-0.87, I²=45%, P=0.18). Six studies investigating cardiogenic shock of any cause determined lower in-hospital mortality in the PAC group than in the non-PAC group (RR 0.84, 95% CI: 0.72-0.97, I²=99%, P<0.01). There was no significant difference in in-hospital mortality between the PAC and non-PAC groups of patients with cardiogenic shock secondary to acute coronary syndrome (RR 1.01, 95% CI: 0.81-1.25, I²=99%, P<0.01).

Conclusions

Overall, our meta-analysis demonstrated no significant association between PAC monitoring and in-hospital mortality among patients managed for cardiogenic shock. The use of PAC in the management of cardiogenic shock caused by acute decompensated heart failure was associated with lower in-hospital mortality, but there was no association between PAC monitoring and in-hospital mortality among patients with cardiogenic shock caused by acute coronary syndrome.

Project description:AimsThe initial bundle of cares strongly affects haemodynamics and outcomes in acute decompensated heart failure cardiogenic shock (ADHF-CS). We sought to characterize whether 24 h haemodynamic profiling provides superior prognostic information as compared with admission assessment and which haemodynamic parameters best predict in-hospital death.Methods and resultsAll patients with ADHF-CS and with available admission and 24 h invasive haemodynamic assessment from two academic institutions were considered for this study. The primary endpoint was in-hospital death. Regression analyses were run to identify relevant predictors of study outcome. We included 127 ADHF-CS patients [65 (inter-quartile range 52-72) years, 25.2% female]. Overall, in-hospital mortality occurred in 26.8%. Non-survivors were older, with greater CS severity. Among admission variables, age [odds ratio (OR) = 1.06; 95% confidence interval (CI): 1.02-1.11; Padj = 0.005] and CPIRAP (OR = 0.62 for 0.1 increment; 95% CI: 0.39-0.95; Padj = 0.034) were found significantly associated with in-hospital death. Among 24 h haemodynamic univariate predictors of in-hospital death, pulmonary elastance (PaE) was the strongest (area under the curve of 0.77; 95% CI: 0.68-0.86). PaE (OR = 5.98; 95% CI: 2.29-17.48; Padj < 0.001), pulmonary artery pulsatility index (PAPi, OR = 0.77; 95% CI: 0.62-0.92; Padj = 0.013) and age (OR = 1.06; 95% CI: 1.02-1.11; Padj = 0.010) were independently associated with in-hospital death. Best cut-off for PaE was 0.85 mmHg/mL and for PAPi was 2.95; cohort phenotyping based on these PaE and PAPi thresholds further increased in-hospital death risk stratification; patients with 24 h high PaE and low PAPi exhibited the highest in-hospital mortality (56.2%).ConclusionsPulmonary artery elastance has been found to be the most powerful 24 h haemodynamic predictor of in-hospital death in patients with ADHF-CS. Age, 24 h PaE, and PAPi are independently associated with hospital mortality. PaE captures ventricular (RV) afterload mismatch and PAPi provides a metric of RV adaptation, thus their combination generates four distinct haemodynamic phenotypes, enhancing in-hospital death risk stratification.

Project description:Although pulmonary artery catheter (PAC) has been used during liver transplantation surgery, the usefulness of PAC has rarely been investigated. We evaluated whether the use of PAC is associated with better clinical outcomes compared to arterial waveform-based monitoring after liver transplantation. A total of 1565 cases undergoing liver transplantation were reviewed. We determined whether patients received PAC or not and divided our cohort into the PAC with hemodynamic monitoring using PAC and the non-PAC with arterial waveform-based monitoring using FloTrac-Vigileo. Propensity score matching was performed. Acute kidney injury (AKI), early allograft dysfunction (EAD) and 1-year all-cause mortality or graft failure were compared in the matched cohorts. Logistic regression analysis was performed in the inverse probability of treatment-weighted (IPTW) cohort for postoperative EAD and AKI, respectively. Five-year overall survival was compared between the two groups. In the matched cohort, there was no significant difference in the incidence of AKI, EAD, length of hospital or ICU stay, and 1-year all-cause mortality between the groups. In the IPTW cohort, the use of PAC was not a significant predictor for AKI or EAD (AKI: odds ratio (95% confidence interval) of 1.20 (0.47-1.56), p = 0.229; EAD: 0.99 (0.38-1.14), p = 0.323). There was no significant difference in the survival between groups after propensity score matching (Log-rank test p = 0.578). In conclusion, posttransplant clinical outcomes were not significantly different between the groups with and without PAC. Anesthetic management without the use of PAC may be possible in low-risk patients during liver transplantation. The risk should be carefully assessed by considering MELD scores, ischemic time, surgical history, previous treatment of underlying liver disease, and degree of portal and pulmonary hypertension.Registration: https://clinicaltrials.gov/ct2/show/NCT05457114 (registration date: July 15, 2022).

Project description:BackgroundThere is paucity of data regarding radiofrequency ablation for ventricular tachycardia (VT) in patients with cardiogenic shock and concomitant VT refractory to antiarrhythmic drugs on mechanical support.MethodsPatients undergoing VT ablation at our center were enrolled in a prospectively maintained registry and screened for the current study (2010-2017).ResultsAll 21 consecutive patients with cardiogenic shock and concomitant refractory ventricular arrhythmia undergoing bailout ablation due to inability to wean off mechanical support were included. Median age was 61 years, 86% were men, median left ventricular ejection fraction was 20%, 81% had ischemic cardiomyopathy, and PAINESD score was 18±5. The type of mechanical support in place before the procedure was intra-aortic balloon pump in 14 patients (67%), Impella CP in 2, extracorporeal membrane oxygenation in 2, extracorporeal membrane oxygenation and intra-aortic balloon pump in 2, and extracorporeal membrane oxygenation and Impella CP in 1. Endocardial voltage maps showed myocardial scar in 19 patients (90%). The clinical VTs were inducible in 13 patients (62%), whereas 6 patients had premature ventricular contraction-induced ventricular fibrillation/VT (29%), and VT could not be induced in 2 patients (9%). Activation mapping was possible in all 13 with inducible clinical VTs. Substrate modification was performed in 15 patients with scar (79%). After ablation and scar modification, the arrhythmia was noninducible in 19 patients (91%). Seventeen (81%) were eventually weaned off mechanical support successfully, but 6 (29%) died during the index admission from persistent cardiogenic shock. Patients who had ventricular arrhythmia and cardiogenic shock on presentation had a trend toward lower in-hospital mortality compared with those who presented with cardiogenic shock and later developed ventricular arrhythmia.ConclusionsBailout ablation for refractory ventricular arrhythmia in cardiogenic shock allowed successful weaning from mechanical support in a large proportion of patients. Mortality remains high, but the majority of patients were discharged home and survived beyond 1 year.
