[As the cardiovascular risk influences the quality and intensity of blood pressure lowering therapy, the goal blood pressure values and the frequency of medical control of hypertensive patients, as well as global risk assessment has an important role in the management of hypertension. In the last couple of years many data have been accumulated showing the poor prognostic value of traditional cardiovascular risk factors. This is the reason why recent Hungarian and international guidelines on the management of hypertension advise the screening for subclinical organ damage. Our goal was to summarize the importance of subclinical organ damage by discussing recently published literature on this topic. An overview has been made on the markers of vascular subclinical damage, like carotid atherosclerosis proved with carotid ultrasonography, peripheral arterial disease assessed with ankle-brachial pressure index measurements and vascular rigidity defined with pulse wave velocity measurements. The prognostic values of myocardial hypertrophy assessed with ECG and/or echocardiography and renal damage proved with decreased estimated glomerular filtration rate and proteinuria are also discussed. Summing up what has been said so far, the assessment of subclinical organ damage has a role in cardiovascular risk prediction, however more randomized and prospective studies have to be performed to define the most suitable (i.e. the most reliable and the most cost-effective) markers for this purpose.]

[On the safety of angiotensin-receptor blockers - A new attack on this drug class]


[Up until now, angiotensin-receptor blockers have been considered to be the safest cardio-, cerebro-, reno- and vasculoprotective drugs. In a previous metaanalysis, ARBs were accused of increasing the risk of myocardial infarction, but a number of metaanalyses and randomised, controlled trials have disproved this hypothesis. In a recent metaanalysis, ARBs were associated with an increased risk of tumours. The author reviews this issue, discusses the flaws of the above metaanalysis and, on the basis of the most up-to-date data in the literature, expert opinions and official statements (FDA, EMA), concludes that members of this drug class should continue to be used according to their approved indications, which is supported by their cardio-, reno-, cerebro- and vasculoprotective effects demonstrated in a number of appropriate, large-scale clinical studies.]

[Evaluation of arterial stiffness in children. Guidelines for the practice]

CSEPREKÁL Orsolya, KIS Éva, SZABÓ J. Attila, REUSZ György

[Assessment of early atherosclerosis and decreased arterial elasticity to recognise the cardiovascular dysfunction in high-risk patients has gained importance in the past decade. Since 1990, more than 630 papers have been published in the adult and pediatric literature. Methods of early risk assessment in adults are well determined in international recommendations. The aim of the present work is to review the suggestions of the American Heart Association helping us to find the most appropriate method for the non invasive methods of cardiovascular assessment of young adults and children. Furthermore, multicentric studies should be conducted to create a Framingham like score system for pediatric patients, to render cardiovascular risk assessment much easier for the every day routine.]

[Update on diagnostics and therapy of the renal artery stenosis in 2010]


[Results of epidemiological studies indicate the atherosclerotic renal artery stenosis is a common condition, thus development of its diagnostics and therapy has significant importance. Renal artery narrowing can cause hypertension, renal function decline, cardiac failure and the increased cardiovascular risk seriously affects survival perspective of the patients. The evolution of MR technology has a prominent role in renovascular diagnostics. Beyond the detection of arterial stenosis this technique is capable of the functional characterization of the stenosis and the detailed description of the regional kidney tissue damage. Based on the results of clinical studies the relevance of revascularization of the renal artery stenosis remains uncertain. The trials focusing on this issue show methodological imperfections. It remains to be elucidated whether these methodological problems will be tackled in the future based on the present information. This review focuses on the actual findings corresponding to these problems.]

[Diuretikumok hypertoniában - 2010]

BARNA István

[Diuretics (especially thiazide derivatives and indapamide that also has vasodilator efficacy) are considered as first line treatment in hypertension. They are particularly favourable in the treatment of overweight, elderly, isolated systolic hypertensive patients suffering from type 2 diabetes and metabolic syndrome or in mild renal and cardiac insufficiency. They can be ideally combined with other antihypertensive agents (primarily with angiotensin-converting enzyme inhibitors, angiotensin receptor blocking agents és béta-blockers). If hypertension is associated with left ventricular hypertrophy or stroke indapamide is the appropriate choice. In case of left ventricular dysfunction and heart failure thiazide and/or furosemide is the adequate option. Low dose diuretics have no clinically relevant side effects and reduce cardiac mortality to the same extent as other pharmaceutical interventions.]

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


[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.]

[Association between cyclothymic affective temperament and hypertension]


[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.]

[Sudden death – ECG – hypertension]


[Sudden death (HH) is not only associated with coronary heart disease or heart failure, but is also present in hypertension, primarily associated with left ventricular hypertrophy, systolic pressure, and age. Co-morbidities of hypertension (diabetes, coronary heart disease, heart failure and renal failure) contribute greatly to its development. HH occurs due to ventricular fibrillation, or asystole. The auther demonstrates depolarization and repolarization pathologies leading to HH and detectable on the ECG and their characteristic ECG patterns. He also emphasizes the importance of resting heart rate and heart rate variability.]

[Prevalence and treatment of hypertension in patients with newly diagnosed familial hypercholesterolemia]

NÁDRÓ Bíborka, DIÓSZEGI Ágnes, KOVÁCS Beáta, PARAGH György, PÁLL Dénes, HARANGI Mariann

[Familial hypercholesterolemia (FH) is an inherited defect of cholesterol metabolism characterized by high plasma total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels and premature cardiovascular disease risk. Prevalence of hypertension in FH is not clarified, but its appearance is independent risk factor for the development of cardiovascular disease. Therefore, optimal treatment has a major priority in this high-risk population. We aimed to investigate the lipid parameters and evaluate the presence of hypertension and its treatment characteristics in 86 newly diagnosed, untreated heterozygous FH patients (27 males, 59 females, mean age 53.6±13.4 years). We diagnosed FH by using the Dutch Lipid Clinic Network criteria. The mean TC level was 8.49±1.7 mmol/l, the mean LDL-C level was 6.11±1.5 mmol/l, the mean high-density lipoprotein cholesterol (HDL-C) level was 1.62±0.5 mmol/l, while the median lipoprotein (a) level was 301 mg/l. We diagnosed 33 FH patients (38.4%) with hypertension. Beta blockers were used in 23, ACE-inhibitors in 13, ARBs in 12, calcium channel blockers in 9, and HCT in 11 cases. 11 patients was treated with monotherapy, for 10 patients double, for 11 patients triple, while for 1 patient quadruple combined antihypertensive therapy was administered. Based on our results, hypertension might be underdiagnosed in this specific patient population. Neither the types nor the combination patterns of blood pressure lowering agents are in line with current guidelines. Up to date screening and treatment of hypertension should be worth considering in this extremely high risk population with enhanced atherosclerosis.]

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


[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.]
