10Background, purpose: The efficacy of the transtelephonic ECG system (TTECG) in the

Introduction The transtelephonic electrocardiogram has been shown to have a great value in the management of out-of-hospital chest pain emergencies. In our previous study it not only improved the pre-hospital medical therapy and time to intervention, but also the in-hospital mortality in ST-segment elevation myocardial infarction. It was hypothesised that the higher in-hospital survival rate could be due to improved transtelephonic electrocardiogram-based pre-hospital management (electrocardiogram interpretation and teleconsultation) and consequently, better coronary perfusion of patients at the time of hospital admission. To test this hypothesis, our database of ST-segment elevation myocardial infarction patients was evaluated retrospectively for predictors (including transtelephonic electrocardiogram) that may influence in-hospital survival. Methods and results The ST-segment elevation myocardial infarction patients were divided into two groups, namely (a) hospital death patients ( n = 49) and (b) hospital survivors (control, n = 726). Regarding pre-hospital medical management, the transtelephonic electrocardiogram-based triage (odds ratio 0.48, confidence interval 0.25–0.92, p = 0.0261) and the administration of optimal pre-hospital medical therapy (acetylsalicylic acid and/or clopidogrel and glycoprotein IIb/IIIa inhibitor) were the most important independent predictors for a decreased risk in our model. At the same time, age, acute heart failure (Killip class >2), successful pre-hospital resuscitation and total occlusion of the infarct-related coronary artery before percutaneous coronary intervention were the most important independent predictors for an increased risk of in-hospital mortality. Discussion In ST-segment elevation myocardial infarction patients, (a) an early transtelephonic electrocardiogram-based teleconsultation and triage, (b) optimal pre-hospital antithrombotic medical therapy and (c) the patency and better perfusion of the infarct-related coronary artery on hospital admission are important predictors of a lower in-hospital mortality rate.

Introduction and aim: The authors examined the pre-hospital delay of patients with ST-elevation myocardial infarction receiving percutaneous coronary revascularization. Method: In the Hungarian Myocardial Infarction Registry (HUMIR), between January 1, 2014 and March 31, 2016, 7146 patients were found who had all necessary time intervals available. In the database of the National Ambulance Service (OMSZ), 3288 patients were found who had the necessary time intervals. The following time intervals were investigated: the time from the beginning of the complaint to the rescue service notification (patient delay time = PDT), the time of the rescue service to arrive at the scene (R1), the on-site care time (R2) and the time from the scene until arriving to the centre (R3). The case of care at the centre, we investigated the time from the onset of symptoms until the balloon inflation (SBI). If the first hospital had no cardiac catheterization laboratory, we measured the transfer time to the cath centre. The methodological details related to the operation of the HUMIR had been described in our earlier communication. Rescue times (R1, R2, R3) were investigated on the basis of the paper-based records of the National Emergency Service. The patients were divided into two groups based on the fact that the first admission hospital is a centre with a heart catheter facility (C) or a non-invasive hospital (H). Results: 2621 patients (79.7%) were admitted to a hospital with cath lab (C) and 667 patients with secondary transport. Patients with primary transport to C were younger, but for other data, the two groups did not differ. The median of PDT for patients in group C was 114, and 121 minutes for patients in group H. There was no significant difference between R1 and R2 time between the two groups. R3 time in group C was longer than for H patients. In the case of secondary transport, the median time was 98 minutes until the centre. The median time from the beginning of the complaint to the balloon inflation (total ischemic time) was 260 minutes in group C and 356 minutes in group H. Conclusion: Based on the analysis of the total ischemic time and the pre-hospital delay, it is clear that the care of myocardial infarction patients can be further improved by reducing the patient’s decision time and increasing the proportion of primary transport. Rescue times (R1, R2, R3) met the expectations, however, further analysis of the M2 time should be considered. Orv Hetil. 2019; 160(1): 20–25.

The aim of this study was to investigate how amenable mortality and related ambulance services differ on a county level in Hungary. The differences in mortality rates and ambulance services could identify counties where stronger ambulance services are needed. The datasets for 2018 consisted of county level aggregated data of citizens between the ages 15–64. The study examined how both the mortality rates and the ambulance rescue deliveries differ from the national average. The analyses were narrowed down to disease groups, such as acute myocardial infarction, hemorrhagic and ischemic stroke. Inequalities were identified regarding the distribution of number of ambulance deliveries, several counties had rates more than double that of the national average. For both mortality and ambulance services some of the counties had significantly better results and others had significantly worse compared to the national average. In Borsod-Abaúj-Zemplén county’s case, hemorrhagic stroke mortality was significantly higher (1.73 [1.35–2.11]), while ambulance deliveries were significantly lower (0.58 [0.40–0.76]) compared to the national average. The research has shown that regarding the investigated mortality rates and ambulance services there are considerable differences between the counties in Hungary. In this regard policy makers should implement policies to tackle these discrepancies.

Absztrakt: Bevezetés és célkitűzés: A szerzők 6878 acut myocardialis infarctus (AMI) miatt kezelt beteg sürgősségi ellátásának adatait elemzik a Nemzeti Szívinfarktus Regiszter és az Országos Mentőszolgálat adatainak felhasználásával. Módszer: A betegeknél 2017. 01. 01. és 2018. 12. 31. között katéteres érmegnyitás történt: 47,5%-uknál ST-elevációval járó szívinfarktus (STEMI), 3614 betegnél (52,5%) nem ST-elevációval járó szívinfarktus (NSTEMI) volt a kezelés indoka. Vizsgálták a panasz kezdete és a mentőszolgálat értesítése között eltelt időt (a betegek késlekedése), a mentés formáját (mentés, illetve szállítás). Elemezték a mentő helyszínre érkezésének (M1), a helyszíni ellátásnak (M2), a kórházba szállításnak (M3) az idejét, valamint a kórházi felvételtől az ér megnyitásáig eltelt időt. Az eredményeket megyék szerinti bontásban is közlik. A medián értékeket és a kvartiliseket (Q1, Q3) tüntették fel. Eredmények: A betegek késlekedése STEMI esetén 101, az NSTEMI-csoportban 687 perc volt. Mentés és azonnali mentőszállítás a STEMI-betegek 58,7%-ánál, az NSTEMI-betegek 43,7%-ánál történt. AMI esetén a mentőegység helyszínre érkezésének (M1) medián ideje 13 perc, a helyszíni ellátás (M2) 23 perc, a helyszínről a kórházba érkezésig eltelt idő (M3) 30 perc volt. STEMI esetén a felvételtől az ér megnyitásáig eltelt idő 37 perc volt. A STEMI-betegek 9,5%-ánál 2 órán belül, 49,1%-ánál 4 órán belül, 88,1%-ánál 12 órán belül került sor az infarktusért felelős ér megnyitására. Ebben a betegcsoportban a teljes ischaemiás idő medián értéke 243 perc volt. Minden vizsgált időperiódus esetén a megyék között jelentős különbségeket találtak. Következtetések: A szívinfarktusos betegek optimális időben történő ellátásának jelenleg a legnagyobb problémája a betegek késlekedése. A mentési idők tekintetében jelentős regionális különbségek vannak, az okok vizsgálatához további elemzések szükségesek. Orv Hetil. 2020; 161(12): 458–467.
