The partial upper sternotomy group had a shorter incision ((9.0 ± 0.8) cm vs. (25.5 ± 1.3) cm, P = 0.02) and smaller postoperative total drainage volume (885 mL vs. 1,820 mL, P = 0.03) than the median sternotomy group. The differences between the 2 groups with respect to other intra-operative indicators such as operation duration, cardiopulmonary bypass duration, aortic occlusion duration, hypothermic circulatory arrest duration, and intra-operative blood loss, and prognostic indicators such as red blood cell infusion, ventilator aid duration, cardiac intensive care unit stay, postoperative hospital stay, and postoperative complications were not significantly different (all P > 0.05).\u0000 \u0000 \u0000 \u0000 The utilization of partial upper sternotomy in patients with type A aortic dissection resulted in a smaller incision and more aesthetically pleasing scar, along with reduced drainage volume compared to median sternotomy.\u0000","PeriodicalId":65676,"journal":{"name":"Cardiology Discovery","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140992333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The majority of these studies have been performed in patients with heart failure and the results have shown first positive effect on blood pressure (BP) reduction. These effects are more pronounced with SGLT2 inhibitors than with GLP-1 receptor agonists. However, the reasons and mechanisms of action inducing BP reduction are still not sufficiently clear. Proposed mechanisms of SGLT2 inhibitors involve the natriuretic effect, modification of the renin-angiotensin-aldosterone system, and/or the reduction in the sympathetic nervous system. GLP-1 receptor agonists have several mechanisms that are related to glycemic, weight, and BP control. Current data show that SGLT2 inhibitors have a stronger antihypertensive effect than GLP-1 receptor agonists, which is mainly related to their renal effect. Briefly, SGLT2 inhibitors increase the response to diuretics and decrease the meal-related antinatriuretic pressure by lowering post-prandial hyperglycemia and hyperinsulinemia and prevent proximal sodium reabsorption. SGLT2 inhibitors can be used as second-line therapy in patients with diabetes mellitus or heart disease and concomitant hypertension. This article aims to summarize current knowledge regarding the antihypertensive effect of SGLT2 inhibitors and GLP-1 receptor agonists.","PeriodicalId":65676,"journal":{"name":"Cardiology Discovery","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139964244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both viral- and myosin-induced myocarditis experimental models are used to mimic myocarditis in humans. Here, coxsackie virus B3 (CVB3)-induced and non-virus-induced myocarditis models and data obtained in clinical studies were reviewed. Experimental murine myocarditis following immunization with α-myosin together with complete Freund adjuvant represents the classical immune-mediated model. T helper 1 (Th1) and Th2 pathways and important cytokines are involved in the autoimmunity of myocarditis, and the dynamic balance between Th17 and regulatory T cell (Treg) seems to have an important role in the process of myocarditis. The purpose of this review is to summarize the existing understanding of the immunological mechanisms underlying myocarditis and exploring gaps in knowledge in both animal and human studies, since these mechanistic insights are a critical requirement for the development of novel therapeutic and vaccination strategies.","PeriodicalId":65676,"journal":{"name":"Cardiology Discovery","volume":"100 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139964082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
