AI Article Synopsis
- Patients with acute myocardial infarction and cardiogenic shock supported by veno-arterial ECMO show high mortality rates, and this study examines the potential survival benefits of percutaneous coronary intervention (PCI).
- Data from 1623 patients was analyzed, revealing that those who underwent PCI had lower in-hospital mortality rates compared to those who did not, along with better outcomes in terms of ECMO weaning success.
- The study concludes that PCI may lower mortality and improve recovery among patients receiving ECMO for AMICS, without increasing the risk of complications related to ECMO.
Article Abstract
Background: Patients suffering from acute myocardial infarction complicated by cardiogenic shock (AMICS), who undergo veno-arterial extracorporeal membrane oxygenation (VA-ECMO) therapy, typically exhibit high mortality rates. The benefits of percutaneous coronary intervention (PCI) in these patients remains unclear. This study aims to investigate whether PCI can mitigate mortality among patients with AMICS supported by ECMO.
Methods: Data from patients ≥18 years, who underwent VA-ECMO assistance in China between January 1, 2017, and June 30, 2022, were retrieved by searching the Chinese Society of Extracorporeal Life Support (CSECLS) Registry. A total of 1623 patients were included and categorised based on whether they underwent PCI. Using propensity score matching, 320 patient pairs were successfully matched. The primary outcome was in-hospital mortality rate. The secondary outcomes included VA-ECMO duration, Hospital stay, ECMO weaning and ECMO related complications.
Results: In the cohort of 1623 patients, 641 (39.5%) underwent PCI. Upon conducting multivariate logistic regression analysis, it was observed that those who underwent PCI had a lower prevalence of hyperlipidemia (13.1% versus [vs.] 17.8%), chronic respiratory disease (2.5% vs. 4.3%) and lower lactic acid (5.90 vs. 8.40). They also had a more significant history of PCI (24.8% vs. 19.8%) and were more likely to be smokers (42.6% vs. 37.0%). Patients in the PCI group exhibited lower in-hospital mortality before and after matching (40.3% vs. 51.6%; = 0.005), which persisted in multivariable modeling (adjusted odds ratio [aOR]: 0.69; 95% confidence interval 0.50-0.95; = 0.024). Patients who received PCI were more successfully weaned from ECMO (88.6% vs. 75.8% before matching). PCI was not a risk factor for ECMO related complications.
Conclusions: Among patients who received ECMO support for AMICS, PCI was associated with a lower rate of in-hospital mortality.

Purpose: The study aimed to compare the diagnostic accuracy of Ga-DOTA-FAPI-04 (Ga-FAPI) and F-FDG PET/CT for peritoneal carcinomatosis (PC) in patients with various types of cancer.
Methods: The study enrolled 113 patients with suspected peritoneal malignancy, each of whom underwent Ga-FAPI and F-FDG PET/CT scans. Lesions in all patients were confirmed through pathology or radiological follow-up.
Cross-Sectional Analyses to Assess the Clinical Safety and Effectiveness of Bisoprolol in Patients With Non-obstructive Coronary Artery Disease Who Underwent Percutaneous Coronary Intervention: A Post-hoc Analysis.

Introduction: Elevated central aortic pressure, cardiac output and peripheral vascular resistance contribute to high morbidity in relation to end organ dysfunction in obstructive and non-obstructive coronary artery disease (NOCAD) cases despite revascularization. Bisoprolol preempts further progression of left ventricular dysfunction in such cases due to anti-ischemic and anti-hypertensive effects, further extending its evaluation in local Indian settings.
Methods: Post-hoc analyses of NOCAD patients with epicardial stenosis (N=378, 30 to 70% stenosis) from cross-sectional analyses conducted across eighty centers in India.
Women with breast implants have higher adjusted abnormal cardiac testing and coronary angiography but lower coronary intervention.

University of Arizona, College of Medicine, Phoenix.
Background: Breast implants interfere with myocardial perfusion imaging (SPECT) and echocardiographic windows leading to increased false positive results. To validate this concept, we hypothesized that patients with breast implants should have higher positive cardiac testing and coronary angiogram with lower percutaneous coronary intervention (PCI) rates compared to women without a breast implant.
Methods: Using ICD 10 codes for breast implants, abnormal results of cardiac functional study, coronary angiogram, and percutaneous coronary interventions, we evaluated any association between these parameters in adult women with breast implants utilizing the National Inpatient Sample (NIS) database.

Background: Patients post-coronary artery bypass graft (CABG) can re-present with acute coronary syndrome (ACS); however, culprit lesion identification, as well as revascularization, is often challenging. Furthermore, the impact of revascularization in this patient group is relatively unknown.
Objectives: The purpose of our study was to evaluate the efficacy of percutaneous coronary intervention (PCI) in patients with previous CABG surgery presenting with ACS.
Introduction: Impella CP is a percutaneous left ventricle assist device used in selected patients undergoing high-risk percutaneous coronary interventions (HR-PCI). To improve outcomes after Impella-supported HR-PCI, institutional Impella programs have been developed.
Objectives: We evaluated the association between the standardized periprocedural management algorithm and outcomes of patients undergoing HR-PCI in the national IMPELLA-PL Registry.
