Background: A retrospective cohort study was conducted to compare the efficacy and safety of direct oral anticoagulants (DOACs) and vitamin K antagonists (VKAs) in the treatment of patients with left ventricular thrombus (LVT).Methods: Consecutive patients admitted to our institution with LVT between February 2009 and December 2020 and treated with either DOACs or VKAs were considered for inclusion in this study. The outcomes included stroke or systemic embolism (SSE), thrombus resolution, and bleeding events.Results: Eighty-seven patients with LVT were identified. Of these, 25 patients were treated with DOACs and 62 patients were treated with VKA. The average follow-up period was 2.37±2.1 years. DOACs were associated with similar incidences of stroke (4.0% vs. 4.8%; P=0.158), systemic embolism (0% vs. 1.6%; P=0.906), SSE (4.0% vs. 6.5%; P=0.657), thrombus resolution (76.0% vs. 74.2%; P=0.057), and blooding events (4.0% vs. 3.2%; P=0.858) as compared to VKAs. In the univariate logistic regression analysis, there was a significant difference between the DOAC and VKA groups in the incidence of SSE when antiplatelets were controlled [odds ratio (OR) =0.34, 95% confidence interval (CI): 0.21, 0.98; P=0.027]. However, in the multivariate analysis, antiplatelets had no significant effect on the outcome (OR =0.41, 95% CI: 0.36, 1.54; P=0.366).Conclusions: DOACs had similar efficacy and safety to VKAs in the treatment of patients with LVT.
Background and aims The scientific community is concerned about cardiovascular disease mortality and morbidity, especially myocardial infarction (MI). Schisantherin A (SCA), a dibenzocyclooctadiene lignan monomer found in S. chinensis fruits has cardiovascular advantages such as increasing NO production in isolated rat thoracic aorta and reducing heart damage caused by ischemia-reperfusion (I/R) through decreasing apoptosis. The present study was undertaken to explore the potential effects of SCA on ISO-induced myocardial infarction in rats. Methods Rats were randomly allocated to four groups: control; ISO-treated, and two additional groups of ISO + SCA (5 or 10 mg/kg body weight). All SCA-treated groups were administered with SCA for 20 days and all ISO groups were challenged with ISO on days 19 and 20. Results SCA significantly attenuated ISO-induced rise in heart/body weight ratio, myocardial infarct size, and cardiac functional biomarkers (CK-MB, cTnI and BNP). SCA pre- and co-treatment resulted in a significant reduction in oxidative stress (via MDA, NO and GSH and increased activities of SOD, CAT and GPx) and inflammation (via decreased levels of TNF-α, IL-6 and IL-1β) markers when compared to the same levels in cardiac tissue of ISO-treated rats. This study also showed that SCA protects ISO-induced oxidative stress and inflammation by activating the PI3K-AKT/Nrf2/ARE pathway and suppressing TLR4/MAPK/NF-κB pathways. Furthermore, SCA treatment protected histopathological alterations observed in only ISO-treated cardiac transverse sections of rats. Conclusion In conclusion, the findings of this study suggest that SCA protects against cardiac injury in the ISO-induced MI model of rats.
