  ABSTRACT: In year 1995 the European Society of Cardiology started an epidemiological study EUROASPIRE to evaluate the results of secondary prevention in some European countries. The first study period was in 1995, the second in 1999-2000 and the third in 2007. From Hungary the same study centers participated in EUROASPIRE I-II-III investigation. Authors present the Hungarian data and changes occurring the last ten years. During the three studies, 1627 coronary patients- younger than 70 years - were evaluated, using standardized methods. In the two Hungarian study centers, the proportion of women and patients older than 60 years increased. The hospital documentation of risk factors improved, at the time of EUROASPIRE III necessary data were found in 89%-99% of patient's records. Mean systolic and diastolic blood pressure continuously decreased between the first and second study period, but at the time of the third study 44% of the patients had elevated blood pressure (>140/90 mmHg). Prevalence of smoking decreased by 8% between second and third study period, however, at the time of the last study, 18% of coronary patients were smokers. The mean of total cholesterol was lower in the last study period comparing to the first investigation (5.6 vs. 5.2 mmol/l). HDL cholesterol level was unchanged and increasing triglyceride values were observed. During the study period the prevalence of obesity continuously increased from 23% to 49%. Prevalence of patients with total cholesterol level 5.5 mmol/l or higher has decreased from 60% to 24%, however 57% of patients did not reach the target level (4.5 mmol/l) although 80% of patients were treated with lipid lowering drugs: 76% of them received statins. Authors say that some part of secondary prevention improved during the last ten years, but many patients did not reach the target blood pressure and cholesterol level and it is embarrassing the prevalence of obesity and diabetes. The published data are not representative for whole Hungary; most probably the general situation is worse. Authors emphasize the importance of secondary prevention in the graduate and postgraduate education. For improving the secondary prevention, better cooperation is needed between hospital staff and patients and general practitioners as well.

• Article: [Endothelial function in high risk cardiovascular patients].

  ABSTRACT: Endothelial dysfunction is caused by risk factors, which have basic, and initial role in atherogenesis. During further progression it is still not known, whether is and how is endothelial dysfunction influenced by risk factors in the late phase of atherosclerosis and/or what kind of other factors play role in endothelial dysfunction. Brachial artery flow mediated vasodilation was examined in 293 high risk patients (vascular 2. type diabetes patients/persons with + 2 risk factors). Relationship between endothelial function and risk factors, and risk stratifications were statistically examined to define the principal predictors of endothelial dysfunction. 1. Examination of flow mediated vasodilation of brachial artery with ultrasound machine, 2. Risk factors evaluating, 3. Vascular examinations: physical, exercise test, Holter monitoring, CW Doppler, duplex scan 4. Risk stratification (10 year risk of fatal vascular events), 5. Statistical analysis (comparative and cohort). 1. Mean endothelial function of 293 high risk patients was reduced (105.1%). 2. Vascular disease plays principal role of the endothelial function in late phase atherosclerosis, because significantly decreases the brachial artery vasodilation (104.3% v. 108.3% p < 0.01) and significantly more (p < 0.0009) endothelial dysfunction can be found in patients with vascular disease than without. 3. Bad risk stratification plays principal role too, because there are significantly (p = 0.012) more endothelial dysfunction in high risk patients, than with better risk stratification. 4. Lipid-, glucose-metabolic alterations, hypertension, age and smoking (all: p = NS) have not already any role in endothelial dysfunction in late phase atherosclerosis. Role of risk factors in initial atherogenesis is scientific evidence, but the role of these factors can not be proved later, when endothelial dysfunction already evolved. In this phase of atherosclerosis the vascular disease and the bed risk stratification have principal role, because they can cause significant more reduction of already reduced endothelial function. Further studies necessary to determine, whether this statistically proved relationship have, or have not any clinical relevance.

• Article: [Correlation of lower extremity Doppler index with flow-mediated vasodilation and the extent of coronary disease].

  ABSTRACT: The aim of this study was to examine relationship between resting ankle-brachial pressure index and flow mediated vasodilation, and that of the extent of coronary artery disease. Authors examined 77 subjects. All had peripheral arterial disease (with ankle-brachial pressure index less than 0.8), and angina pectoris (coronary artery disease verified by coronary angiography). Mean age was 64.6 years (range 41-82 years). Flow mediated (endothelial dependent) vasodilatation was measured for all participiant. Authors stated, that ankle-brachial pressure index significantly correlates with flow mediated vasodilatation and the same connection can be supposed between Doppler index and coronary artery disease's extension.

  ABSTRACT: Flow-mediated vasodilatation of brachial arteries, a non-invasive parameter of endothelial function, is correlated with cardiovascular risk factors. An impairment of flow-mediated vasodilatation in the brachial artery is related to the extent of coronary artery disease. The authors examined the relationship between flow-mediated vasodilatation and coronary artery disease morphology in young patients who had myocardial infarction. 28 young patients (all men) with myocardial infarction (age 22-40, mean age: 35 years). Coronarography revealed one vessel disease in 16 patients (A group) and multivessel disease in 12 patients (B group). The control group was 14 healthy, young patients (age 18-36 years mean age: 30 years) (C group). The authors examined in all subjects flow-mediated, endothelium-dependent vasodilatation following reactive hyperaemia and nitroglycerin induced (NTG), endothelium-independent vasodilatation in the brachial artery with high resolution ultrasound (Acuson 128 X P/10). Patients after myocardial infarction showed impaired flow-mediated vasodilatation compared to those of controls. (p < 0.01). Flow-mediated vasodilatation was lower in multivessel disease compare to one vessel disease. Nitroglycerin induced similar degrees of vasodilatation in the myocardial infarction and control groups. Young patients with myocardial infarction may have impaired endothelium-dependent dilatation and the decrease of flow-mediated vasodilatation is related to the angiographic extent of coronary artery disease.
