[Mechanism of action and role of cilostazol in treatment of peripheral arterial disease]
[Intermittent claudication is a typical symptom of lower extremity arterial disease. Cilostazol is a reversible, selective phosphodiesterase-3 inhibitor which has antiplatelet, antithrombotic and vasodilator effects. It is indicated to improve maximal and pain-free walking distance in patients with intermittent claudication in the absence of rest pain or peripheral tissue necrosis. It can be beneficial in diabetic patiens with intermittent claudication, as it has been proved to prevent the development of foot ulcers. In combination with acetyl-salicylic acid it may help maintain stent patency after endovascular intervention and stent implantation. Cilostazol is contraindicated in heart failure. With cilostazol, a clinically proven effective drug has become available in the treatment of intermittent claudication which could improve walking and life quality of patients.]

[Effects of peripheral resistance lowering and elevating beta-blockers on central blood pressure - nebivolol in focus]
[Central blood pressure, that is, blood pressure (BP) in the ascending aorta, is considered an important physiologic parameter as it reflects the hemodynamic relationship between the heart and the aorta, both in systole and in diastole. In the systolic phase, central BP represents the pressure against which the left ventricle has to eject blood during systolic contraction. Thus, central arterial pressure reflects both left ventricular stroke volume and afterload, defines cardiac work, and contributes to the development of left ventricular hypertrophy in hypertensive individuals. In the diastolic phase, central BP is a key determinant of the blood flow delivery to the myocardium. Despite the increasing knowledge regarding the importance of central blood pressure and the availability of non-invasive measurement technics it couldn’t spread in everyday clinical practice and rarely or not mentioned in the therapeutic guidelines. The different antihypertensiv drugs significantly differs based on their effects on central blood pressure particularly β-blockers. The so-called ’classical’ β-blockers have un - favourable effect on central blood pressure due to increasing peripherial vascular resistance. In the opposit the vasodilating β-blockers including nebivolol markedly decrease central blood pressure which could explain their beneficial effects.]

[Cilostazol in therapy of peripheral atherosclerotic patients]
[INTRODUCTION - Cilostazol is available in Hungary for patients with peripheral atherosclerotic disease (PAD) since June 2014. PATIENTS AND METHOD - In this prospective clinical data collection 68 patients were investigated with PAD-CI, treated with cilostazol. All patients were in stage of Fontaine II at the beginning of the study. Every patient has been able to control for at least three months. Two investigated groups have been treated with cilostazol. Group I: patients operated on lower extremity with femoropopliteal bypass earlier of this study and group II: patients with PAD but no arterial reconstruction in their medical record. Every patient got 100 mg cilostazol twice a day. Anticholesterol, platelet inhibition treatment have been continued in every case. No patients have taken pentoxifyllin. The end points of the data collection were the walking distance alteration (elongation) expressed in meter and the changing of the complaints of claudication intermittent. 61 patients have tolerated cilostazol treatment without side effects. Seven patients out of 68 have not tolerated it, that is why the treatment was suspended. Thirty-four out of 61 patients’ walking distance was elongated with at least 50 meters. 21 patients’ claudication improved between 50 to 100 meters and 12 patients’ walking distance improved more than 100 meters. CONCLUSION - The cilostazol presumably will be an unavoidable factor in the effective treatment of peripheral atherosclerotic disease. ]

[Genetic diagnostics of the trombosis risk]
[The cardiovascular system and the coalugation process play essential role in regulating the homestasis of the human body. Thrombuses may appear in veins (venous thrombosis) as well as arteries (arterial thrombosis) that may cause a wide range of ischemic vascular diseases. By mapping genetic risk factors that may accelarate the development of thrombosis, the quality of medical preventions and therapies can be improved. The most frequent gene mutations (FII, FV, PAI-1, MTHFR and EPCR gene polimorphisms) can be tested by methods based on PCR, real-time PCR and macroarray techniques. Professionals may use genetic results for selecting appropriate and optimal therapies based on the context of a patient’s medical history.]

[Serum uric acid in primary hypertension: cause or consequence? - Data from SEPHAR II Survey]
[Objectives: To evaluate a possible link between serum uric acid (SUA) levels, arterial stiffness and atherogenic index of plasma on one hand and renal function on the other and to test the role of SUA in the assessment of total cardiovascular risk. Materials and methods: We studied serum uric acid levels (SUA) in 1975 subjects included in SEPHAR II survey. We measured arterial stiffness parameters, calculated atherogenic index of plasma and estimated glomerular filtration rate (eGFR) by MDRD and CKD-EPI formulae and assessed total cardiovascular risk according to current ESH-ESC risk stratification chart. Results: The highest SUA values were recorded in subjects with grade III HT and were correlated with increased arterial stiffness and with increased atherogenic index of plasma. The lowest eGRF values, assessed by both MDRD and CKD-EPI, were observed among subjects with hyperuricemia and a significant indirect correlation between SUA and eGFR was evidenced. A proportional correlation between SUA values and total CV risk was also obtained. Conclusions: The study supports SUA implication in the pathogenesis of elevated blood pressure and the role of uric acid as a cardiovascular risk factor, particularly for the development of hypertension and renal disease.]

[Impaired aortic elastic properties in young females with migraine]
[Migraine is a common health problem affecting women more commonly. It has been associated with an increased risk for cardiovascular events. In this study, we investigated whether aortic elastic properties is altered in migraineurs with low cardiovascular risk compared with healthy controls, in order to elicit further evidence on tentative association between migraine and increased risk of cardiovascular disease. Methods - Forty-three migraine patients with low CVD risk were enrolled to the study. Thirty-three volunteers, with a similar age and sex distribution served as a control group. Following parameters of the aortic elasticity were calculated: aortic strain, aortic stiffness (β) index and aortic distensibility. Results - Aortic strain was not statistically different between the study and control group. However, aortic distensibility and β index were significantly impaired in patients with migraine compared to control subjects Discussion - The elastic properties of the aorta in migreineurs may be different from normal by using easily available echocardiographic methods. This information may be a clue for clarification of cardiovascular system involvement in migraine.]

[Blood presssure paradoxon in very elderly patients]
[The paper is warning for the necessity of very complex consideration before taking antihypertensive therapeutic decisions (indication, point or points of actiou, blood pressure target levels, dynamics of BP reduction, etc) for elderly hypertensive patients. Blood pressure reduction can mean efficient protection against cardiovascular events also among the elderly hypertensives. However in those old and very old hypertensive patients who have not only severe stiffness of their large vessels but suffer in advanced co-morbidities and integrated pathologic geriatric syndromes, the blood pressure reduction can result in sometimes even life threatening general deterioration. Antihypertensive therapeutic dilemmas of elderly caregivers appear mainly in relation to old hypertensive patients of age over 80 years. For this „very old” age period the HYVET study gave us evidence based conclusions about the cardiovascular protective usefulness of combined antihypertensive treatment resulting in BP reduction to 150 Hgmm systolic BP target levels. However a non-negligable rate of selection of the included patients in HYVET study can weaken the generalizability of the HYVET findings in this age period and the extensibility of its antihypertensive therapeutic conclusions for the entire „very old” population because this population has also a high proportion of patients with chronic progressive illnesses and general decline. Thus the elderly hypertensives’ caregiver must always carefully and critically balance between the messages of the HYVET and the nonselective observational follow up studies among elderlies showing frequently the so-called epidemiologic blood pressure/ mortality paradoxon. The paper is also trying to find potencial pathomechanical interpretations and point of actions for the epidemiologic blood pressure/mortality paradoxon found in the very old population.]
