[The renin-angiotensin-aldosterone system (RAAS) is involved in the regulation of electrolyte and water balance primarily; however, it also influences vascular function and increases blood pressure - especially under pathological conditions. Hypertension, post-myocardial infarction state, and heart failure are, for example, associated with excessive systemic and/or local activation of the RAAS. Angiotensin II (AT-II) generated by the latter contributes - along with additional factors and through its deleterious effects (vasoconstriction, endothelial dysfunction, atherosclerosis, prothrombotic state, fibrosis, etc.) - to damage to the target organs involved in the sequence of cardiovascular events. Inhibiting the RAAS at different levels is of therapeutic importance - its purpose is to delay disease progression, to prevent end organ damage, and to achieve a better outcome. As AT-II acts on several (AT1 and AT2) receptors, using angiotensin receptor blocking (ARB) agents with a high selectivity for the AT1 receptor is the rational choice. In view of its favourable therapeutic properties and efficacy demonstrated by morbidity and mortality studies, a generic formulation of appropriate quality, containing valsartan as active substance could prove to be the ideal treatment for patients with hypertension and other cardiovascular disorders.]

[What is worth to know about COVID-19 for (not only) a cardiologist]

HEPP Tamás, CSÉKE Balázs, BENCZÚR Béla

[SARS-CoV-2 virus infection sprang from Wuhan the capital of the Chinese Hubei province, at the end of 2019 and caused a worldwide pandemic with 1.5 million confirmed cases and claimed almost 100 000 victims until the beginning of April, 2020. First analyses of Chinese COVID-patients confirmed that diabetes, hypertension, and cardiovascular diseases were highly prevalent among SARS-CoV2 infected patients, and might be associated with poor outcome. As previously shown for SARS-CoV-1, SARS-CoV-2 similarly utilizes ACE2 as receptor for viral alveolar cell entry. A suspicion has arisen that the widely used ACE-inhibitor/ARB therapy could be potentially harmful for patients suffering from COVID-19 infection as these agents upregulate the ACE2-expressions. From the other point RAAS-blockade might be beneficial due to fact that ACE2 counters the deleterious effects of Angiotensin II. Authors provide a comprehensive over­view of the most recent literature and summarize the link between COVID-19 and car­diovascular disease. It is important to em­phasize that there are no available hu­man evidences confirming if the RAAS-in­hi­bitor therapy were harmful or helpful in pa­tients suffering from COVID-19.]
