AUGUST 20, 2002

Lege Artis Medicinae - 2002;12(08)

[INTRODUCTION AND METHODS - Quality monitoring activities are essential for improving the care of acute coronary patients. The aim of our study was to establish a registry and assess the adherence to widely used quality indicators. We investigated two groups of patients, those admitted to our Intensive Care Unit with the diagnosis of acute myocardial infarction (Group 1) and unstable angina (Group 2). RESULTS - Group 1. consisted of 173 patients, of whom 60% was eligible for thrombolysis. In 5 cases no acute reperfusion therapy was done. For reperfusion we used systemic thrombolysis in 74% and primary coronary angioplasty in 26%. The prehospital delay was 150 minutes, the ”door-to-needle” time and the ”door-toballoon” time were 30 minutes and 102 minutes, respectively. 95% of the patients received aspirin, 79% beta-blocker, 82% angiotensin converting enzyme inhibitor and 39% cholesterol lowering medications. Group 2. included 84 patients, most of them had high risk features according to the Braunwald classification and the American College of Cardiology, American Heart Association guideline. Coronary angiography was performed in 80 cases. Regarding revascularization, 43 patients underwent coronary bypass surgery, 30 percutan angioplasty with stent implantation in 18. In this group aspirin was given in 82, unfractionated heparin in 9, low molecular weight heparin in 49, glycoprotein IIb/IIIa inhibitor in 15 cases. 21 patients received intravenous nitroglycerin, 70 patients betablocker and 57 patients cholesterol lowering drugs. DISCUSSION - Quality management is extremely useful in assessing our practice, our shortcomings and developments.]

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


[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.]

[Gestational diabetes mellitus and neuropathy: examining the relationship]


[BACKGROUND - Little is known about the relationship between gestational diabetes and late diabetes complications. The relationship between these abnormalities was investigated in this study. PATIENTS, METHODS - Besides reclassification of their glucose tolerance, the prevalence and correlating factors of diabetic neuropathy were evaluated in 123 gestational diabetic (GDM) women controlled prior by our team during their pregnancies. 26 pregestational type 2 diabetic patients served as controls. Mean follow-up time was 7.2 years. Vibration perception threshold was measured to diagnose peripheral neuropathy, while cardiovascular autonomic neuropathy was evaluated using the battery of four cardiovascular reflex-tests. RESULTS - From 123 prior GDM women, 63 were characterized as having diabetes (52.9%), while 14 had impaired glucose tolerance (11.8%). Peripheral neuropathy was diagnosed in 23.6 %, parasympathetic neuropathy in 37.4 %, while sympathetic neuropathy was confirmed in 7.3 % of the patients evaluated during follow-up visit. Association between abnormal glucose tolerance and neuropathy was statistically significant only in the case of parasympathetic neuropathy (p=0.0001), and this relationship was independent from elevated BMI, microalbuminuria and the higher rate of hypertension observed in these women (p=0.006). Since the number of abnormal neuropathy tests were also higher than expected in women with normal glucose tolerance, we hypothetised a cross-sectional link between neuropathy and insulin resistance. An additional analysis comfirmed this association between insulin resistance and parasympathetic neuropathy independent of metabolic status of these patients (p=0.005). CONCLUSIONS - The importance of gestational diabetes, which is sometimes underestimated by many clinicians, was highlighted by our study since it projected a high frequency of parasympathetic cardiovascular neuropathy in these patients. This form of diabetes not only projects the development of late onset type 2 diabetes, but could also act as a predictor of late diabetes complications. According to our results diabetic parasympathetic neuropathy may be linked to type 2 diabetes/ insulin resistance syndrome, and could play a role in the excess cardiovascular mortality observed in these patients.]

[Physicians’ attitudes and suppositions in 2001 in the Polyclinic of the Hospitaller Brothers in Budapest]


[INTRODUCTION - Following the total socioeconomic changes in Hungary in 1989, no scientific analysis has been made about physicians' religious attributes in the new circumstances. These attributes, after four decades of political anticlericalism may affect essentially the ideological and socio-economic patterns of medical professionalism. Hungary’s 2001 census favoured such an inquiry, since it went back to the traditional questions about religious affiliations. METHODS - The ”sensitive” questions ot the census were accepted without any obstacle in the whole population and backed up the present study together with the newly established religious atmosphere in the hospital of roman catholic Hospitaller Brothers of St. John of God, which was reopened on the 1st of July, 2000. The collection of data started in November 2000 ending in December 2001. All 98 full time employed physicians participated in the inquiry carried out by personal interviews guided by the same 51 questions. Following more than half a century span, the aim of the present study was to gain measurable information about the doctors’ unknown religious affiliation and its impact on clinical problems with ethical dimensions. RESULTS - All the doctors cooperated willingly in face-to-face interviews. There was a high proportion of religious affiliation (83 persons out of 98) without any sign of mysticism in the professional values. However, the pre-eminent role of psychological factors in the healing process was stressed, opposed to the simplified materialism of medicine. The same ideological pattern was represented while ranking other professions in the social hierarchy. No physicians experienced a conflict between their religious belief and professional activity in the dayto- day service. CONCLUSION - According to the extremely underpaid medical profession in Hungary, doctors of the new hospital do not believe that now they should tolerate their underpaid status as altruistic missionaries. However, they know exactly that balancing professionalism and business of medicine, is not a task for a single hospital but an urgent one of the whole society.]

[In ancient times medical practitioners already knew that heart rate is a measure of the general condition of the soul and body. Worldwide epidemiologic studies in the past decades indicated that decreased resting heart rate, a parameter that can be simply measured, has a favourable direct effect on cardiovascular risk. This consistent beneficial risk-reducing effect can be clearly shown in the asymptomatic general population as well as in patients with hypertension, stable coronary artery disease, acute myocardial infarction and congestive heart failure irrespective of gender, age or ethnic origin. In the asymptomatic general population this beneficial effect is mainly due to reduced early coronary artery disease events and diminished risk of sudden cardiac death. Population studies have clearly shown that decreasing resting heart rate - either by physical exercise or medical treatment - improves cardiovascular survival, and decreases the overall and cardiovascular mortality. It seems reasonable to conclude that in modern pharmacotherapy of cardiovascular disease the use of selective heart rate lowering drugs that directly act on the pacemaker activity of the sinus node (If-channel blockers) are warranted.]

[Myocardial infarction in systemic lupus erythematosus]

BOLF Zsuzsanna, KOVÁCS Mónika, LUPKOVICS Géza

[Systemic lupus erythematosus (SLE) is a multisystemic autoimmune disease with relatively common cardiovascular morbidity and mortality. We present a case of a 56-year-old woman treated for SLE, who had an infection of the upper respiratory tract and fever followed by multiple cardiac symptoms: pericarditis, endocarditis and finally acute myocardial infarction (AMI), which was attributed to coronaritis. Acute PCI resulted in revascularisation and combined drug therapy also reduced the patient’s inflammatory symptoms. Our case draws attention to the fact that SLE, as well as diabetes, is a condition equivalent with ischaemic heart disease.]

TÖRÖK Marietta, OROSZ Attila, CHARLOTTA Wollheim, JÖRGEN Hegbrant

[A dialysis provider’s core activities include providing dialysis care with excellent quality, ensuring a low variability across the clinic network and ensuring strong focus on patient safety. In this article, we summarize the pertinent components of the quality assurance and safety program of the Diaverum Renal Services Group. Concerning medical performance, the key components of a successful quality program are setting treatment targets; implementing evidence- based guidelines and clinical protocols and revising targets, guidelines and clinical protocols based on sound scientific data. Consistently, regularly, prospectively and accurately collecting data from all clinics in the network; processing collected data to provide feedback to clinics in a timely manner. The key activities for ensuring patient safety include a standardized approach to education, i.e. a uniform education program including control of theoretical knowledge and clinical competencies; implementation of clinical policies and procedures in the organization in order to reduce variability and potential defects in clinic practice. We point out the importance of auditing clinical practice on a regular basis. By applying a standardized and systematic continuous quality improvement approach throughout the entire organization, it has been possible for Diaverum to progressively improve medical performance and ensure patient safety]

[Calcitonin-like receptor (CL-R) is a functional CGRP1- receptor when complexed with RAMP1 or an adrenomedullin-receptor or when complexed with RAMP2 or RAMP3. This study was carried out 1. to set up a method to examine the relative quantity of mRNA of CL-R, RAMP1, RAMP2 and RAMP3 in human coronary (CA), pulmonary (PA) and middle cerebral arteries (MCA), and 2. to examine the level of mRNA expression in cerebro- and cardiovascular diseases. The method was validated with respect to the use of postmortem tissue and we compared β-actin and GAPDH as housekeeping genes. There was no time-dependent change in total RNA and level of mRNA for β-actin or GAPDH could be detected in vessels removed from 1 and 5 days post mortem. The expression of β-actin appears lower in coronary artery than in pulmonary artery and middle cerebral artery with no significant difference for GAPDH; both worked well. There were some differences in mRNA expression for CL-R (higher) and RAMP3 (lower) in middle cerebral artery compared to coronary artery and pulmonary artery. There was no significant difference in mRNA for RAMP1 and RAMP2 in the three types of arteries. We did not observe any difference in mRNA for CL-R and RAMPs in arteries from patients with hemorrhagic stroke, arteriosclerosis and acute myocardial infarction when compared to patients without these diagnoses. Thus the mRNA expression seems to be unaltered in these disorders.]

[Left ventricular remodelling and chronic heart failure as a consequence of myocardial infarction is a major problem despite of the everimproving therapeutic options. The available treatment methods have fairly limited success in preventing the development of these changes. Myocardial regeneration with stem cell treatment is a promising therapeutic alternative. Although the results should still be confirmed in large, randomised, multicentric controlled trials, data from animal studies and small clinical trials suggest that therapy with stem cells after acute myocardial infarction is safe and feasible, is able to reduce the extent of necrosis, and may improve myocardial perfusion and left ventricular function. This review presents the types of cells that can be used, the ways of application, and the available results of clinical trials of stem cell therapy after acute myocardial infarction.]
