[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.]

[Importance of Reynolds-score system on cardiovascular risk assessment]


[The author summarizes knowledge about Reynolds risk assessment system based on data of references and own experiences. The first part of article is about how the results of study of pathogenesis of atherosclerosis were converted into new risk assessment systems. One result of this process is the Reynolds system wich is consisted of traditional riks factors, high sensitive C-reactive protein and the patients’ family medical history. He demonstrates essence of Reynolds system and process of it’s validity. The author deals with comparison of Reynolds system with other traditional risk assessment systems. The practical issues of application of Reynolds system are detailed in the conclusion of the article.]

[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.]

[Nonsteroidal antiinflammatory drugs (NSAIDs) are among the most frequently used medicines all over the world. In the year 2012 in the LAM, we summarized data on cardiovascular (CV) safety of these drugs. We emphasized that all NSAIDs may potentially be harmful on the CV system, as they can increase the blood pressure, the risk of coronary events (angina, myocardial infarction), and that of stroke, as well as they may deteriorate renal functions. We also outlined that in this respect there are substantial differences between different compounds, and the CV risk does not depend on the ratio of COX- 1/COX-2 selectivity. The newly available data of original papers and metaanalyses shed light on further details. Even naproxen which drug was previously considered the less harmful on CV system can increase the risk of blood pressure, stroke, and gastrointestinal (GI) complications. We have to emphasize that the most important risk of NSAIDs is still the GI bleeding. This adverse effect is significantly less for drugs which are more selective for COX-2 than COX-1 enzyme, but other, pleiotropic effects can also beneficially modify the GI as well as the CV risk. E.g. the aceclofenac was found to be among NSAIDs with the less adverse effects on GI system and is also among those having the less CV risk.]

[Polyphenols, which belong to the group of flavonoids, can be found in a number of plants, and are present in a high concentration in the French maritime pine bark. The authors summarise results of large-scale experimental and clinical studies on pycnogenol, the standardised extract of French maritime pine bark. Pycnogenol decreases production and effects of free radicals (antioxidant effect). It has antiinflammatory properties, and, by the stimulation of eNOSsynthesis, it increases the production of vasodilatory compounds (e.g. NO, prostacyclin) and decreases that of vascoconstrictor compounds (endothelin-1, thromboxane) materials. These changes lead to vasodilation, which results in increased tissue perfusion and decreased blood pressure. Pycnogenol also decreases platelet aggregation and LDL-cholesterol level and increases HDL-cholesterol level. Its antidiabetic effect has also been shown. Consequently, it may substantially decrease cardiovascular risk. In addition to these results, pycnogenol has been also found to have antibacterial and antiviral effects. It has been successfully used in children with attention deficit hyperactivity disorder, as well as in adults with dysmenorrhea, climacterial disturbances, glaucoma or asthma bronchiale.]

[Cholesterol-lowering is not the Holy Grail, but neither is the work of the devil]


[Cholesterol-lowering statins are the most tested medications in respect of the effects and side-effects. Based on these, we can safely claim that most of the negative opinions about cholesterol-lowering are not realistic. It is not a panacea, but it is proven that around a 30% of cardio- and cerebrovascular risk reducation can be achieved by their regular taking, while the incidence of side effects and risks are at least one order of magnitude lower in each patient groups. For cholesterol, there is no “normal” lab threshold or low level, only “target values”, since the mean value in the general population is high in regard of atherosclerosis (the values measured at birth and among natural people can be considered normal). Let us appreciate the cholesterol- lowering medications because we do not have a large armamentarium!]
