Lege Artis Medicinae - 2003;13(01)

[From pathophysiological point of view, the kidney is an integral part of the cardiovascular system. Renal diseases adversely affect the cardiac functions, and disturbances of the cardiovascular system affect adversely renal functions, causing either the decrease of left ventricular functions or manifesting in overt chronic heart failure. Regarding the cardiac manifestations of renal diseases, characteristic features are the symptoms of left ventricular volume and pressure overload, the metabolic effects of the ”uremic toxins” and the frequent infections associated with dialysis and compromised immunologic state, the secunder hyperparathyreosis, as well as the associated conditions like hypertension, diabetes mellitus and coronary atherosclerosis. All these can be the explanation for the frequent cardiovascular death of chronic kidney disease patients. It also stresses the outstanding importance of the decrease of cardiovascular hazard of chronic renal disease patients. The strategy should comprise of an adequate antihypertensive treatment (ACE-inhibitor, AT-II blocking and calcium antagonist), strong antidiabetic control of diabetic patients and the adequate treatment of dyslipidaemia (if exists), as well as antithrombotic aspirin treatment.]

[Errors and mistakes in laboratory medicine]

ENDRŐCZI Elemér

[The unacceptable results of laboratory testing derive from the insufficient preanalytical, analytical and postanalytical processes. In addition to the analytical errors, there are inappropriate testing orders which reflect the failures of diagnostic strategy, and either result in excess testing orders without additional new informations, or in the lack of testing order that would be necessary for efficiency of patient's care. An increasing number of study demonstrate that in majority of cases the cause of erroneous results can be traced back to mistakes in the preanalytical phase (preparation of patient, sample collection). The total quality of the diagnostic strategy depends both on the compliance of tests according to the health condition of patient and the quality performance of laboratory processes. The elimination of the preanalytical errors and the formulation of proper diagnostic strategy requires a close cooperation between physicians and the diagnostic workplaces as well as the application of multidisciplinary guidelines which specify the quality requirements of the whole diagnostic process. Such guidelines are not prepared for specific professional activities and do not replace lower-level professional standards (e.g. for test procedures). Based on evidence-based medicine and the recommendations of international experts such guidelines should cover all elements of quality assurance necessary to achieve efficient diagnostic strategy and testing. There is little doubt that such recommendations will also be useful for rational financing of the health care system.]

[Hungarian Hypertension Study - EMMA]

NAGY Viktor, HORVÁTH Attila, MOLNÁR Katalin, BLASKÓ György, DE Châtel Rudolf

[INTRODUCTION - Ischaemic heart disease and stroke show rapidly increasing incidence and lead mortality statistics in developed countries. Hypertension is the main risk factor for both diseases. With the support of Hungarian Society of Hypertension we performed a public opinion survey on hypertension and on the medicines of its treatment among Hungarian adults between October and December 2001. SUBJECTS AND METHODS - The Omnibus investigation using standardised questionnaires was carried out by monthly home interviews of 5000 participants. RESULTS - One aim of the study was to determine the prevalence of hypertension and the usage of drugs in the population over 35 years. Persistent high blood pressure had been diagnosed in 39% of these population (n=1360). When choosing drugs the lack of side effects is the most important characteristic beside efficacy in this age group. As the study results show, physicians consider regular blood pressure control and screening programs as most important factors for patients with hypertension. CONCLUSION - The results of EMMA study revealed habits and attitudes of regular drug intake. Results also outline the characteristics of the desirable drug that are best accepted by patients - drugs, which patients are faithful to.]

[Experience with coenzyme Q10 in heart failure]

KOHUT László

[INTRODUCTION - The protein complex coenzyme Q10 (CoQ10) has a role in ATP production as a mitochondrial electron transport molecule, and it also has a strong antioxidant effect. Several studies have proved the correlation between the decrease in CoQ10 level and the severity of heart failure. Heart failure is a multifactorial syndrome, the development of which is greatly influenced by an abnormal energy metabolism. CASE REPORT - The 61-year-old woman developed heart failure after a myocardial infarction. She complained of fatigue, dyspnoea and reduced physical endurance even with optimal treatment. When her therapy was completed by CoQ10, her endurance and life quality significantly improved and her symptoms ameliorated. CONCLUSIONS - Medical treatment of chronic heart failure is an evidence-based, complex therapy. Despite the complex management, morbidity and mortality of this condition remain high. A number of studies have shown that CoQ10 substitution can improve the clinical and haemodynamical parameters of patients with heart failure. On the basis of these results, the use of CoQ10 as an adjuvant therapy to complex treatment has an increasing role.]

[Cardiovascular prevention - Opportunities of risk reduction, 2010]

NAGY András Csaba

[10 years of experience following the millennium has confirmed again that data on long term cardiovascular morbidity and mortality can be influenced by effective prevention most substantially. Growing body of knowledge and experience in the field of modern cardiovascular prevention is available, but novel and novel milestone studies have been published leading to updating of guidelines, however, we cannot be satisfied with the results. Evidence suggest that despite recent efforts, Hungarian cardiovascular morbidity and mortality has not been reduced significantly and except for some success - acute ST elevation myocardial infarction care in accordance with the European standard - we are behind the other EU countries in cardiovascular mortality of the active (age 30-65 years) age group. Recently several interesting contradiction has been published in the field of prevention, like the effectiveness of aspirin as primer prevention, which changes our common prevention conception. Data have to be also addressed, which can explain the controversial results from a different point of view. Now we are talking about the results of REALITY study, which highlight not only the noncompliance of the patient but that of the physician as well.]

[The importance of endothelial dysfunction and possibilities of its treatment in chronic heart failure]

MOHÁCSI Attila, LIZANECZ Erzsébet

[Endothelial cells - under autocrine and paracrine control - may have a central role in the regulation of vascular tone. Endothelial dysfunction is a very early sign of heart failure but the clinical consequence is not well understood. Recent evidence suggests that upregulation of the neuro-endocrine-, and the renin-angiotensin-aldosterone system would lead to increased tissue- and circulating angiotensin-II levels. Elevated concentration of angiotensin-II provides a mechanism by which vasomotor responses to nitric oxide, prostaglandins are blunted, while the effects of vasoconstrictors such as thromboxans, endothelin and chatecholamins are enhanced. The higher basal vascular tone leads to the degeneration and atrophy of skeletal muscle, moreover to the the ischaemic damage of myocardial cells. Because renin-angiotensinaldosterone system is under genetic control, the deleterious effects of angiotensin-II depends on the angiotensin-converting enzyme gene. Pharmacological attempts to counteract endothelial dysfunction in heart failure may include the angiotensin-converting enzyme inhibitor, which can potentially improve the endothel dependent vasodilatation response. The importance of measuring endothelial function by non-invasive techniques is yet unknown, thus, before we introduce the widespread testing of patients for endothelial function, more research has to be done.]

[POST-INFARCTION CARDIAC FAILURE]

TOMCSÁNYI János

[Recent advances in the care of acute myocardial infarction have resulted in more patients surviving myocardial infarction than earlier. However, heart failure is a common complication in these patients, which in turn is associated with substantial mortality, primarily due to a remodelling of the left ventricle that already starts in an early stage of the myocardial infarction. The aim of this review article is to present the pathomechanism of this remodelling and to discuss related therapeutic options. Current guidelines recommend the use of an angiotensin- converting enzyme inhibitor combined with or followed by an angiotensin receptor blocker, a beta-blocker, and an aldosterone antagonist in post-infarction patients with concomitant heart failure.]

[HOW DIABETOGENIC IS STATIN THERAPY?]

CSÁSZÁR Albert

[According to the latest guidelines, the goal in cardiovascular prevention is to achieve an LDL-cholesterol level no higher than 1.8 mmol/l in the high risk and extra high risk groups. According to international recommendations, statin should be used at the highest tolerable dose rather than any combination treatments. In a number of cases, higher doses are associated with increased side effects, which rarely affect liver enzymes and CK-parameters. A metaanalysis published in 2011 made it clear that higher statin doses compared with low-medium doses can increase the occurence of newonset diabetes by about 12%. This is presumably a class effect, which is not significant according to the guidelines, and which is much lesser than the benefits of this therapy in the prevention of cardiovascular events, thus, it obviously does not question the justification of statin treatment. However, the observed association implies that during statin therapy of nondiabetic patients, blood glucose control should be performed every year, and, if needed, an oral glucose tolerance test should be performed to detect the potential development of diabetes.]
