MedicalResearch.com: What is the background for this study?
Response:Transcatheter left atrial appendageal closure (LAAC) has become an established therapeutic approach for prevention of stroke in subjects with non-valvular atrial fibrillation who are ineligible for long-term oral anticoagulation. Device-related thrombus (DRT), developing after LAAO procedures occurs in a small proportion but patients receiving these devices but is associated with critical embolic events such as ischemic stroke. Thrombogenicity and delayed endothelialization of fabric play a role in the development of DRT. Fluorinated polymers are known to have thromboresistant properties which may favorably modify blood biomaterial interactions of a LAAO device.
In this study we compared the thrombogenicity and endothelial coverage (EC) after left atrial appendage occlusion (LAAO) between a novel fluoropolymer-coated Watchman (FP-WM (Watchman FLX PRO) and the conventional uncoated Watchman FLX (WM).

MedicalResearch.com: What is the background for this study?
Response: Our research team has been researching the roles of environmental and genetic determinants of chronic diseases for nearly three decades, with special emphasis on evaluating micronutrients, minerals, and trace elements in relation to cardiometabolic outcomes, and findings of which have contributed to the design of several large, randomized trials of dietary supplements in the US (Liu JAMA 1999; 2011; Diabetes Care 2005a,b; Diabetes 2006). Several large intervention trials have consistently shown beneficial effects on clinical cardiometabolic outcomes of a diet pattern rich in micronutrients, although research on micronutrient supplementation has mainly focused on the health effects of a single or a few vitamins and minerals.
We decided to take a comprehensive and systematic approach to evaluate all the publicly available/accessible studies reporting all micronutrients including phytochemicals and antioxidant supplements and their effects on cardiovascular risk factors as well as multiple CVDs.

Response: Racial and ethnic disparities affect cardiac transplantation outcomes. In cohort analyses of racial and ethnic groups from the previous three decades, Black patients were constantly at a higher risk of mortality after cardiac transplantation. In 2018, the United Network for Organ Sharing (UNOS) revised the allocation system to expand access to organs for the most medically urgent patients and reduce disparities and regional differences. We sought to evaluate contemporary trends and impact of the new 2018 allocation system.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Omega-3 fatty acids are incorporated into the phospholipids of cellular membranes, including cardiac contractile cells, and have a wide range of demonstrated physiological effects. Several potential mechanisms have been investigated, including antiarrhythmic, anti-inflammatory, and endothelial.
Omega-3 fatty acids lower heart rate and improve heart rate variability, both associated with lower sudden cardiac death risk, one of the complications that may occur after a myocardial infarction.
Increased omega-3 fatty acids also enhance arterial elasticity by increasing endothelium-derived vasodilators, which is associated with blood pressure–lowering effects.
They also have a cardioprotective effect on platelet-monocyte aggregation, and lower triglyceride levels.
