Many studies focus on finding and refining new effects of statin drugs. In addition to the main lipidlowering effect (blocking cholesterol synthesis), statin drugs have a number of pleiotropic effects, including negative effects. The main beneficial effects of statin drugs on the components of the cardiovascular system are: anti-ischemic, antithrombotic, anti-apoptotic, antioxidant, endothelioprotective, anti-inflammatory properties, and a number of other beneficial effects. Due to these effects, statin drugs are considered one of the main therapeutic agents for the management of patients with cardiovascular pathologies. To date, many review manuscripts have been published on the myotoxicity, hepatotoxicity, nephrotoxicity, neurotoxicity and diabetogenic effects of statins. However, there are no review manuscripts considering the negative effect of statin drugs on myocardial contractile cells (cardiomyocytes). The purpose of this review is to discuss the negative effects of statin drugs on cardiomyocytes. Special attention is paid to the cardiotoxic action of statin drugs on cardiomyocytes and the mechanisms of increased serum levels of cardiac troponins. In the process of preparing this review, a detailed analysis of laboratory and experimental data devoted to the study of the negative effects of statin drugs on cardiomyocytes was carried out. The literature search was carried out with the keywords: statin drugs, negative effects, mechanisms, cardiac troponins, oxidative stress, apoptosis. Thus, statin drugs can have a number of negative effects on cardiomyocytes, in particular, increased oxidative stress, endoplasmic reticulum stress, damage to mitochondria and intercalated discs, and inhibition of glucose transport into cardiomyocytes. Additional studies are needed to confirm and clarify the mechanisms and clinical consequences of the negative effects of statin drugs on cardiomyocytes.</p>","PeriodicalId":9535,"journal":{"name":"Cardiovascular and Hematological Agents in Medicinal Chemistry","volume":" ","pages":"7-16"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9111627","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 presence of neurological complications after COVID allowed neuropathologists to investigate in-depth the role of viral infection in neurons. The pathophysiology of the post-COVID neurological syndrome involved the development of a systematic response, including coagulopathy characterized by the formation of microthrombi. Coagulopathy, an old term for a new disease, describes the discrepancy between pro-coagulant and anticoagulant systems due to overexpression of pro-coagulant substances and or their receptors in addition to suppression of the anticoagulant molecules and or their receptors. Vascular endothelial cells and hepatocytes play a central role in the regulation of hemostasis that is disrupted during the acute phase response (APR) of coronavirus-19 (COVID-19). Currently, coagulopathy and inflammation are termed together since both form a complementary system, indicated by the elevation of inflammatory biomarkers (APR) and fibrinolysis biomarkers (D-dimer/fibrin). The later events of post-COVID neurological syndrome are primarily induced by coagulopathy and direct viral tropism.

Aspirin affects platelet function through irreversibly inhibiting the activity of cyclooxygenase, and it reduces the risk of thrombosis. The current systematic review was aimed to evaluate the effectiveness of aspirin in preventing prothrombotic states in COVID-19 hospitalized patients.\u0000\u0000\u0000METHODS\u0000The systematic search was done in PubMed/Medline, EMBASE, and Medrxiv up to September 27, 2021. The following keywords were used: \"COVID-19\", \"SARS-CoV-2\", \"2019 Novel Coronavirus\", \"Aspirin\", and \"Acetylsalicylic Acid\".\u0000\u0000\u0000RESULTS\u0000Twelve studies were included. In COVID-19 patients, aspirin can reduce CRP, IL-6 levels, and platelet aggregation by inhibiting thromboxane A2. It can also improve antiviral immunity by hindering the biosynthesis of prostaglandins and lipoxin. Eight out of twelve articles indicated that aspirin provided a beneficial effect in COVID-19. Most studies consider lowered mechanical ventilation needs, ICU admission, illness severity, overt thrombosis, and clinical outcomes in COVID-19 patients receiving aspirin.\u0000\u0000\u0000CONCLUSIONS\u0000Aspirin as an antiplatelet and anti-inflammatory agent may reduce the mortality rates in hospitalized patients with severe COVID-19. Further observational studies are necessary to determine the effect of aspirin on the prevention of prothrombotic states in hospitalized COVID-19 patients.
