[Hypertension is important even in the group of common diseases. Cardiovascular mortality could be significantly reduced if high blood pressure could not only be treated, but controlled as well. The newly introduced fixed combination perindopril-amlodipin-indapamide medication could be a good tool for genereal practitioners, specialists in internal medicine and cardiologists. Combined treatment with the ACE inhibitor perindopril, the new vasorelaxant type diuretic indapamide and the third generation type Ca-chanel blocker amlodipin is effective in reducing blood pressure. Besides effectivity the organ protective pleiotrop qualities (cardioprotective, plakk stabilising, antiatherosclerotic, antithrombotic, stroke preventive, endothel dysfunction reducing, renal protetcion granting) provide a long lasting beneficial impact on life expectancy and a better quality of life to the patients. If we choose the right dosage, we could raise the compliance level of patients resulting in excellent degrees of compliance. In our article we wanted to draw attention to the major evidencies which are the best acknowledgements of this triple combination although we didn’t explore all avenues.]

[Hypertension and left ventricular hypertrophy]


[Left ventricular hypertrophy (LVH) is defined as an increase in the mass of the left ventricle. In addition to the absolute increase in mass, the geometric pattern of LVH also may be important. LVH can be secondary to an increase in wall thickness, an increase in cavity size, or both. LVH as a consequence of hypertension usually presents with an increase in wall thickness. This increase in mass predominantly results from a chronic increase in afterload of LV caused by the hypertension, although there is also a genetic component. A significant increase in the number and/or size of sarcomeres is the main pathologic mechanism, but hypertension may also result in interstitial fibrosis. The estimation of mass is commonly derived from measurements obtained by echocardiography. LVH is associated with increased incidence of systolic and/or diastolic dysfunction, heart failure, myocardial infarction, ventricular arrhythmias, sudden cardiac death, aortic root dilatation, and a cerebrovascular event. The cardiovascular risk is directly related to the degree of mass. The regression of LVH is associated with a reduction in cardiovascular risk and improved cardiac function. Regression of LVH is associated with weight loss, dietary sodium restriction, and use of ACE inhibitors, ARBs, some calcium channel blockers, and some sympatholytic agents.]

[Prevalence of overweight and obesity in hypertensive patients]

KISS István, PAKSY András, KÉKES Ede

[Authors had performed an anthropometric analysis using a database of 2011-2013 of Hungarian Hypertension Register. They analyzed overweight and obesity in relation of age. The results were compared with similar analysis conducted in the total population 2015. They analyzed the prevalence of visceral obesity as well using the waist circumference measurement categories and these were also compared with screening data of total population. The prevalence of overweight and obesity was very high in both genders, co-occurrences exceeded 70% between 45-70 years. The prevalence was significantly higher in hypertensives, than in the total population. The prevalence of visceral obesity measured by waist circumference was also high, especially in women whose reached 50% of cases. They observed a significant difference between hypertensive and total populations In category „danger” of visceral obesity]

[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.]

[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.]

[Effect of age on the function of renin-angiotensin system]


[Angiotensin II (Ang II) by activating angiotensin type 1 receptors (AT1R) is one of the most potent vasoconstrictors in the regulation of vasomotor tone and thus systemic blood pressure. In this study, we hypothesized that aging alters Ang II - induced vasomotor responses and expression of vascular mRNA and protein angiotensin type 1 receptor (AT1R). Thus, carotid arteries were isolated from newborn, young, middle age, old and senescent rats and their vasomotor responses were measured in a myograph (DMT-600) to repeated administrations of Ang II. Vascular relative AT1R mRNA level was determined by qRT-PCR and the AT1R protein density was measured by Western blot. Contractions of vessels to the first administration of Ang II increased from newborn to young and middle age rats then they decreased to senescent rats. In general, second administration of Ang II elicited reduced contractions, but they also first increased and then they decreased to old age. Similarly, the AT1R mRNA level and the AT1R protein density increased from newborn to young and middle age rats then they decreased to senescent rats. The pattern of these changes correlated with functional vasomotor data. We conclude that aging (newborn to senescence) has substantial effects on Ang II-induced vasomotor responses and AT1R signaling suggesting that it is - and thus regulation of systemic blood pressure is - determined primarily by genetic programs.]

[Deeper analysis of nebivolol effects]


[Author presents the formation of nitric oxide as a largest vasodilator of human endothelium as well as the endothelial dysfunction a result of formation at adrenergic stimulus. He demonstrates in detail the benefits of selective β-1 blocker and β-3 adrenergic agonist nebivolol in the vascular system. This drug has also receptor independent effects. Complex effects of nebivolol causes vasodilation, inhibits oxidative stress and it is capable to neutralize the effects of free oxygen radicals and as a result the endothelial function will be better. Its clinical effects and the less wellknown beneficial properties are listed. The use of drug is discussed especially in hypertensives with smoking, COPD or PAD. The β-3 agonist effect provides positive reactions not only in the adipocytes and the myocardial tissue. but in the skeletal muscle as well: Increase in energy expenditure - as a compensatory mechanism - is increased in obesity and the glucose uptake + storage on skeletal muscle cells are increased in hyperglycemia. The insulin sensitivity will be better, leptin level is decreased, adiponectin level is increased by nebivolol. It is assumed this drug has antidiabetic and anti-obesity effects.]

[Angiotensin-converting enyzme inhibitors before and after myocardial infarction]


[In this review current knowledge related to the coronary atherosclerosis and angiotensin-enzym inhibitor is discussed. The earlier recognition to the effect of ACE inhibitors and ARBs to slow or reverse left ventricular remodelling is well known and accepted but the effect of these drugs on the atherosclerotic process itself may be aqual important. The focus should be now how to treat the early phase of coronary atherosclerosis, how to treat safety the hypertensive patient in the setting of coronary stenosis, how to treat the acute myocardial infarction’s patient with renal failure, and at least how to improve the long-time adherence in the primer and secunder prevention too.]
