High prevalence of hyperlipidaemia in patients with AV re-entry tachycardia and AV nodal re-entry tachycardia.

Diet rich in lipids and hyperlipidaemia increases incidence of atrial premature beats and all supraventricular arrhythmias. The aim of the study was to investigate the prevalence of hyperlipidaemia in patients with AV re-entry tachycardia (AVRT) and AV nodal re-entry tachycardia (AVNRT). We conducted a retrospective, cross-sectional, case-control study that included all consecutive patients for whom AVRT or AVNRT was confirmed during electrophysiology study. Age and gender-matched patients admitted to hospital or outpatient clinic for various reasons were randomly included and served as a control group. Hyperlipidaemia was defined according to 2016 European Society of Cardiology guidelines. A total of 1448 subjects were included: 725 patients with AVRT/AVNRT and 723 controls. AVRT/AVNRT patients had high hyperlipidaemia prevalence, which was significantly higher when compared to the control group (50.1 vs. 35.8%, p < 0.001). AVRT patients, with median age of 37.5 years, had hyperlipidaemia prevalence of 45.7%. In a multivariate analysis, hyperlipidaemia was independently associated with AVRT/AVNRT (OR 2.128, p < 0.001), both with AVNRT (OR 1.878, p < 0.001) and AVRT (OR 2.786, p < 0.001). Hypercholesterolemia was significantly more prevalent in patients with AVNRT and AVRT, while this was not the case for hypertriglyceridemia. There were no differences between the AVRT and AVNRT patients regarding hyperlipidaemia prevalence (51.9 vs. 45.7%, p = 0.801), even though AVRT patients were significantly younger (37.5 vs. 48.5, p < 0.001). In conclusion, this is the first study that investigated hyperlipidaemia prevalence in patients with AVRT or AVNRT. AVRT/AVNRT patients had higher prevalence of hyperlipidaemia and higher total and LDL cholesterol levels.

ROUTINELY AVAILABLE BIOMARKERS AS LONG-TERM PREDICTORS OF DEVELOPING SYSTOLIC DYSFUNCTION IN COMPLETELY REVASCULARIZED PATIENTS WITH ACUTE ST ELEVATION MYOCARDIAL INFARCTION.

The aim of this study was to assess the efficacy of high-sensitivity C-reactive protein (hsCRP), cardiac troponin T (cTnT) and creatine kinase (CK) as long-term predictors of reduced systolic function in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) with complete revascularization. This prospective study evaluated consecutive patients with acute STEMI who had normal left ventricular ejection fraction (LVEF ≥50%) at admission with single-vessel disease and underwent complete revascularization. Blood samples were collected from admission to day 7. The primary endpoint was reduction of LVEF <50% after 12 months. The study included 47 patients, median age 59±10 years, 74.5% of them men. Patients who developed systolic dysfunction (LVEF <50%) had significantly higher mean values of cTnT after 24 hours (5.11 vs. 2.82 µg/L, p=0.010) and peak values of CK (3375.5 vs. 1865 U/L, p=0.008). There was no significant relation between hsCRP and development of reduced LVEF (p=0.541). In conclusion, cTnT and CK could serve as long-term predictors of reduced left ventricular systolic function (<50%) in acute STEMI patients with normal systolic function at admission, single-vessel coronary disease and complete revascularization during primary PCI.

Burnout among Croatian physicians: a cross sectional national survey

AIM: To investigate the prevalence of burnout syndrome among physicians of all specialties, including residents and non-specialists, on a national level in Croatia. METHODS: This cross-sectional study, conducted in October 2017, used anonymous online survey based on the Maslach Burnout Inventory Human Services Survey. The Croatian version of the inventory was assessed for acceptability, factorial validity, and reliability. Key dimensions of burnout - emotional exhaustion, depersonalization, and lack of personal accomplishment were assessed. Respondents scoring high for emotional exhaustion or depersonalization were defined as burned-out. RESULTS: The response rate was 18% (2557/14 427). Respondents' median age was 41 years (range 25-80), and 68% (1737/2557) were women. Good sampling adequacy and scale reliability were confirmed. Factorial validity suggested the presence of three overall factors, and no items were eliminated. Sixty-three percent of physicians were burned-out. High score on emotional exhaustion, depersonalization, and reduced personal accomplishment were found in 58%, 29%, and 52% of respondents, respectively. As many as 16% of the respondents simultaneously experienced high levels of all three burnout dimensions. Multivariate logistic regression analysis revealed that residents and physicians in tertiary or primary care were at an increased risk of burnout, while physicians working in institutes were at a decreased risk. CONCLUSION: Active national measures are needed to reduce the high prevalence of burnout among Croatian physicians.

[SATISFACTION OF YOUNG DOCTORS IN CROATIA: ARE WE HEADING IN THE RIGHT DIRECTION]? / ZADOVOLJSTVO MLADIH LIJECNIKA U REPUBLICI HRVATSKOJ: IDEMO LI U PRAVOM SMJERU?

Introduction: The satisfaction of junior medical doctors is primarily associated with the training they receive during the residency period and working conditions. Given a considerable brain-drain of medical doctors from the Republic of Croatia, the present research focused on the evaluation of the satisfaction of junior medical doctors. Methodology: The Junior Doctors Committee of the Croatian Medical Chamber prepared a questionnaire on the satisfaction of junior doctors. The relevant questionnaire was available for filling in online in the period from February 1 to March 20, 2016. Results: The questionnaire was completed by 1,531 persons aged between 29 and 35 (mean age 32) of which 67% were females. A 58% of respondents would leave the Republic of Croatia if offered an opportunity. The main reasons for leaving the country include better working conditions (74%), well-regulated healthcare system (64%) and higher wages (64%). In case of staying in the country, their future professional status and development would remain unaltered (44%). Conclusion: The questionnaire results show a high level of dissatisfaction with the healthcare system, some segments of the specialist training and the mentor role. The analysis of factors affecting the satisfaction of junior doctors will facilitate the preparation and adoption of measures aiming to mitigate the above-mentioned trend.
