[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.]

[Myocardial infarction in systemic lupus erythematosus]

BOLF Zsuzsanna, KOVÁCS Mónika, LUPKOVICS Géza

[Systemic lupus erythematosus (SLE) is a multisystemic autoimmune disease with relatively common cardiovascular morbidity and mortality. We present a case of a 56-year-old woman treated for SLE, who had an infection of the upper respiratory tract and fever followed by multiple cardiac symptoms: pericarditis, endocarditis and finally acute myocardial infarction (AMI), which was attributed to coronaritis. Acute PCI resulted in revascularisation and combined drug therapy also reduced the patient’s inflammatory symptoms. Our case draws attention to the fact that SLE, as well as diabetes, is a condition equivalent with ischaemic heart disease.]

[Anti-atherosclerotic effect of pioglitazone - The first evidence of the role of triglyceride/HDL ratio]

CSÁSZÁR Albert

[The presence of multiple risk factors can multiply exponentially the risk of cardiovascular events, thus cardiovascular diseases are more severe in diabetes mellitus. One of the challenges we face today is the application of drugs that, besides improving glucose homeostasis, also have antiatherosclerotic effect. Such candidates are glitazones, which have pleiotropic efficiency beyond their main effect: they improve distribution of adipose tissue, blood pressure and endothelial function and also have anti-inflammatory and anti-coagulation capacity. Regarding the effects on lipid metabolism, there are differences between various glitazones: improvements are mainly achieved by pioglitazone, which markedly reduces triglyceride levels, and also elevates HDL levels and decreases the ratio of small, dense LDL-particles. Studies on clinical outcomes also show the superiority of pioglitazone. Imaging of blood vessels (carotis-IMT, intracoronary ultrasound technique) also suggest a greater efficiency of pioglitazone. According to the latest analysis of the PERISCOPE study, the stability of the coronary plaque was associated only with the triglyceride/ HDL ratio in case of pioglitazone. The newest data also revealed that pioglitazone uniquely increases the cholesterol-efflux attributed to HDL-related macrophages. On the basis of the latest results, pioglitazone not only improves glucose homeostasis, but also has a remarkable anti-atherosclerotic effect, which is primarily due to its favourable lipid metabolism profile.]

[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.]
