[Hypertension and hypercholesterolaemia often co-occur and promote early cardiovascular disease. Previous studies have shown that antihypertensive treatment may be more effective if LDL cholesterol is also reduced. This may be due to the increased expression of angiotensin-1 receptor in hypercholesterolaemia, which increases peripheral vascular resistance through angiotensin-2, and adversely affects endothelial and smooth muscle cells. Other authors indicate that high cholesterol levels increase the production of angiotensin-2 through the activation of the chymase system. High cholesterol levels increase the amount of circulating oxidized LDL which binds to the transmembrane oxidized LDL receptor (LOX- 1) also activates the angiotensin-1 receptor. In addition, angiotensin-2 has an effect on intracellular cholesterol synthesis by enhancing the key enzyme of the synthesis of intracellular cholesterol, HMG-CoA reductase. The authors present the studies that support cholesterol lowering can contribute to lowering blood pressure and other major meta-analyses in which the beneficial effects of cholesterol lowering and lipid lowering on blood pressure reductions were not proven. In the background, it may well be that these studies are not designed to evaluate the effect of cholesterol-lowering drugs on hypertension in patients with hypercholesterolaemia, and non-statin-treated patients are not randomized.]

[Statins for elderly people, in primary prevention?]

BAJNOK László

[In a recent, retrospective cohort study, statin usage in primary prevention was found being not beneficial for patients (i) without diabetes over 75 years of age, and (ii) with diabetes over 85 years of age (75-84 years total mortality of diabetics was also lower). These findings are in sharp contrast to the two outstanding, double-blind, placebo controlled, randomized, a primary prevention studies done with rosuvastatin. Of these, 50% reduction in LDL-C in JUPITER was associated with a 50% reduction in risk and 25% reduction in LDL-C in HOPE-3 with 25% reduction in risk. Furthermore, subgroup analyzes did not indicate lower efficacy for the elderly. The recommendation of the European Atherosclerosis Society for primary preventions of the elderlies recommending consideration of statin use in these cases (Class IIa) is particularly relevant, especially in the presence of other risk factors such as hypertension. In the primary prevention lipid treatment, we can see quite clearly till 75 years of age and hopefully, we will even further after learning about the results of STAREE, a study that is designed to elderly and in which 40 mg atorvastatin is applied.]

[Sexual problems in CKD – a narrative review]

TÖRÖK Marietta, JÖRGEN Hegbrant, GIOVANNI Strippoli

[Sexual dysfunction is highly prevalent in patients with CKD, especially those receiving dialysis. Given the high prevalence of sexual problems in CKD patients, there has been growing interest in finding effective treatments for sexual dysfunction. PDE5i and zinc have been found promising interventions for treating sexual dysfunction in men with CKD in a systematic review of RCTs, but the evidence supporting their routine use in CKD patients is limited. In the Collaborative Depression and Sexual Dysfunction (CDS) Study, over a cohort of 1611 men in hemodialysis, 83% reported erectile dysfunction and 47% reported severe erectile dysfunction, with depression strongly correlated to this problem. Similarly, sexual dysfunction was highly prevalent in women undergoing hemodialysis. Of the 659 respondents, 555 (84%) reported sexual dysfunction and more than half of sexually active women reported sexual dysfunction, associated with age, depressive symptoms, menopause, low serum albumin, and diuretic therapy.]

[Association between cyclothymic affective temperament and hypertension]

NEMCSIK János, BATTA Dóra, KŐRÖSI Beáta, RIHMER Zoltán

[Affective temperaments (cyclothymic, hypertymic, depressive, anxious, irritable) are stable parts of personality and after adolescent only their minor changes are detectable. Their connections with psychopathology is well-described; depressive temperament plays role in major depression, cyclothymic temperament in bipolar II disorder, while hyperthymic temperament in bipolar I disorder. Moreover, scientific data of the last decade suggest, that affective temperaments are also associated with somatic diseases. Cyclothymic temperament is supposed to have the closest connection with hypertension. The prevalence of hypertension is higher parallel with the presence of dominant cyclothymic affective temperament and in this condition the frequency of cardiovascular complications in hypertensive patients was also described to be higher. In chronic hypertensive patients cyclothymic temperament score is positively associated with systolic blood pressure and in women with the earlier development of hypertension. The background of these associations is probably based on the more prevalent presence of common risk factors (smoking, obesity, alcoholism) with more pronounced cyclothymic temperament. The scientific importance of the research of the associations of personality traits including affective temperaments with somatic disorders can help in the identification of higher risk patient subgroups.]

[Thiazide- or thiazide-like diuretics should be used in the treatment of patients with hypertension? Particularities of the situation in Hungary]

VÁLYI Péter

[Diuretics have remained the cornerstone of the antihypertensive treatment since their widespreading in the 1960s. According to the 2018 ESC/ESH Guidelines for the management of arterial hypertension, in the absence of evidence from direct comparator trials and recognizing that many of the approved single-pill combinations are based on hydrochlorothiazide, this drug and thiazide-like indapamide can be considered suitable antihypertensive agents. In the 2018 Hungarian guidelines indapamide is named as the most efficacious diuretic in the treatment of patients with hypertension. The aim of the publication is redefining thiazide- and thiazide-like diuretic use in the treatment of hypertensive patients, with particular attention to presently available hydrochlorothia­zide and indapamide, and their combination drugs in Hungary.]

[Hypertension, COPD and COVID-19. Focus on antihypertensive therapy]

FARSANG Csaba

[Chronic obstructive pulmonary disease is a very common comorbidity of hypertension and it is often unrecognised by physicians. The factors involved in the pathomechanism of both diseases should be realised when choosing treatment. Among factors, hypoxia, increased tone of sympathetic nervous system and activation of renin-angiotensin-aldosterone system should primarily be considered. Vascular wall damage and endothelial dysfunction has an important role in both conditions. The goals of treatment are elimination of risk factors, optimizing the blood pressure, the consequential prevention of cardio-cerebrovascular, renal and pulmonary damage; finally prolonging the patients’ life and improving their quality of life as well. Both hypertension and COPD significantly worsen the condition of COVID-19 patients since they increase the severity of the disease and the rate of in-patients’ and their mortality. In the treatment of hypertension among COPD and COVID-19 patients there must be emphasized the medication inhibiting of renin-angiotensin-aldosterone system, such as angiotensin-converting en­zyme inhibitors or angiotensin-II AT1 re­cep­tor antagonists. Special attention concerned the beneficial effect of mineralocorticoid receptor antagonist spironolactone. Other antihypertensive drugs (calcium channel blockers, thiazide-like diu­retics, high selectivity β1 receptor antagonists) may supplement the treatment if necessary. Long-acting β2 receptor agonists, muscarinic receptor antagonists and inhalation corticosteroids may be administered in double or triple combination also in hypertension and COPD as well. It is important to note, that statin therapy and also vitamin D3 improve the condition of COVID-19 patients.]

[Monitoring of the blood pressure lowering effectiveness of ramipril-amlodipine fix combination – a non-interventional trial (RAMONA study)]

TOMCSÁNYI János

[Purpose: Monitoring the effectiveness and safety of the fix combination formulation Egiramlon® therapy containing ramipril and amlodipin in patients, suffering from mild or moderate hypertension despite antihypertensive treatment. Patients and methods: Open, prospective, phase IV clinical observational study, which involved 9169 patients (age >18) with mild or moderate hypertension [TUKEB No: 16927- 1/2012/EKU (294/PI/12.)]. Ramipril/Amlodipin 5/5, 5/10, 10/5, 10/10 mg combinations were administered/ titrated in three visits, during the four months period according to the physician’s decision Blood pressure was measured by validated blood pressure sphygmomanometry and ABPM (Meditech, Hungary). The dosis of the fix combination formulation was determined individually during the visits by the 923 doctors involved in the study. The target blood pressure value was 140/90 mmHg, but in case of high risk patients population (diagnosed cardiovascular disease, diabetes), 130/90 mmHg target value was determined. Results: In 70.1% of the patients had no protocoll deviation. Patients data and examination results were processed according to this 6423 patient population. The average age of the patients were 60.2 year, in 50-50% sex distribution. The average duration of the treated hypertension was 9.8 years and the average blood pressure value was 157/91 mmHg. Till the end of the study, systolic blood pressure has decreased with 26.4 mmHg and diastolic pressure with 11.8 mmHg. An average 5.5 bpm heart rate frequency decreasing was observed at the end of the study. As a result of the treatment 52.4% of the patient population has reached the target blood pressure value.]

[Clinical implication of arterial stiffness in the elderly]

BENCZÚR Béla

[Hypertension prevalence and cardiovascular risk gradually with age. However this aging process seems to take a more rapid course in some individuals, as reflected in the Early Vascular Aging (EVA) syndrome. Age and high blood pressure are the two main determinants of arterial stiffness which is the core of EVA: the impaired elasticity of the media layer of large elastic arteries (mainly the aorta), a process that can be measured by pulse wave velocity. In elderly hyperten­sives, large arteries stiffen and systolic and pulse pressures increase, due to wave reflections. Arterial stiffness has predictive value for future CV e.g. events, coronary artery dis­ease, stroke, and vascular dementia and even all-cause mortality. The concepts of EVA (Early Vascular Aging) and SUPERNOVA (Super­normal Vascular Aging, the opposite phenotype of EVA) help to understand why early target-organ damages develop in some individuals and why others remain much more “younger” than their chronologic age. New drugs are being developed to treat EVA when lifestyle intervention and conven­tional risk factor controlling drugs are not enough.]
