MI model was created by occluding left anterior descending (LAD) artery for 30 minutes and reperfusion was established for 14 days by opening this artery. Diosgenin (50 mg/kg) was given orally to the rats for 21 days (from 7 days before MI induction until the end of the 14-day reperfusion period). Cardiac injury markers including troponin I, creatine kinase-MB (CK-MB), and lactate dehydrogenase (LDH) were measured using enzyme-linked immunosorbent assay (ELISA), same as cardiac stress oxidative markers (superoxide dismutase (SOD), Malondialdehyde (MDA), reduced glutathione (GSH)).

The statistical analysis for pooling the results of diagnostic performance parameters was conducted using Stata and Meta-DiSc softwares.</p><p><strong>Results: </strong>Thirty-eight included studies in this meta-analysis were published between 2006 and 2024, encompassing a total of 6,783 patients. There was significant heterogeneity between included studies with respect to sensitivity (I<sup>2</sup>=92.51 and P<0.01) and specificity (I<sup>2</sup>=93.79 and P<0.01). The pooled sensitivity, specificity, and accuracy of LUS for detection of heart failure were 0.92 (95% CI, 0.87-0.95), 0.90 (95% CI, 0.86-0.93), and 0.96 (95% CI, 0.94-0.98), respectively. In addition, pooled positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic odds ratio (DOR) were 7.87 (95% CI, 5.60-11.07), 0.14 (95% CI, 0.10-0.19), and 70.74 (95% CI, 41.98-119.21), respectively.</p><p><strong>Conclusion: </strong>Our meta-analysis demonstrates that LUS is a highly practical imaging for diagnosing acute heart failure, with excellent sensitivity, specificity, and accuracy. It is particularly valuable for excluding the heart failure when the result is negative. However, the influence of outlier and influential studies warrants caution, and future studies should aim to further validate these findings in diverse clinical contexts.</p>","PeriodicalId":8146,"journal":{"name":"Archives of Academic Emergency Medicine","volume":"13 1","pages":"e33"},"PeriodicalIF":2.9,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11868670/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inadequate organ perfusion and frequent CPR-related trauma most likely occur due to inappropriate adaptation to hemostatic conditions, electrophysiology, cardiotorsal anatomy, and thoracic biomechanics. Alternatively, we propose a new technique compromising chest compressions through the 5<sup>th</sup> intercostal space while placing the victim in the left lateral decubitus position with wrapped abdomen and raised legs, allowing to: bypass the sternal barrier, <i>refill</i> the heart, and then <i>recoil</i>-<i>rebound</i> the chest (3R /CPR), within the axis of the cylindrical ribcage.
