Abstract
BACKGROUND COVID-19 is a viral disease notorious for frequent worldwide outbreaks. It is difficult to control, thereby resulting in overload of the healthcare system. A possible solution to prevent overcrowding is rapid triage of patients, which makes it possible to focus care on the high-risk patients and minimize the impact of crowding on patient prognosis. METHODS The triage algorithm assessed self-sufficiency, oximetry, systolic blood pressure, and the Glasgow coma scale. Compliance with the triage protocol was defined as fulfillment of all protocol steps, including assignment of the correct level of care. Triage was considered successful if there was no change in the scope of care (e.g., unscheduled hospital admission, transfer to different level of care) or if there was unexpected death within 48 hours. RESULTS A total of 929 patients were enrolled in the study. Triage criteria were fulfilled in 825 (88.8%) patients. Within 48 hours, unscheduled hospital admission, transfer to different level of care, or unexpected death occurred in 56 (6.0%), 6 (0.6%), and 5 (0.5%) patients, respectively. The risk of unscheduled hospital admission or transfer to different level of care was significantly increased if triage criteria were not fulfilled [13.1% vs. 76.1%, RR 5.8 (3.8-8.3), p < 0.001; 0.5% vs. 5.2%, RR 11.4 (2.3-57.7), p = 0.036, respectively]. CONCLUSION The proposed algorithm for triage of patients with proven COVID-19 is a simple, fast, and reliable tool for rapid sorting for outpatient treatment, hospitalization on a standard ward, or assignment to an intensive care unit.

Point-of-Care Cardiac Ultrasound Training Programme: Experience from the University Hospital Hradec Králové. Emerg Med Int 2024; 2024:9974284. [PMID: 38222095 PMCID: PMC10787655 DOI: 10.1155/2024/9974284] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 10/02/2023] [Accepted: 12/08/2023] [Indexed: 01/16/2024] Open
Abstract
Point-of-care ultrasound examinations performed by physicians of different specialties are a rapidly growing phenomenon, which has led to a worldwide effort to create a standardised approach to ultrasound examination training. The implementation of emergency echocardiography by noncardiologists is mainly aimed at the standardisation of the procedure, a structured training system, and an agreement on competencies. This article summarises the current training programmes for nonechocardiographers at the University Hospital in Hradec Králové. In cooperation with cardiologists specialised in cardiac ultrasound (ECHO), an extended acute echo protocol dedicated to emergency department physicians was developed and validated in daily practice. According to our retrospective evaluation, after one year of clinical practice, we can confirm that point-of-care ultrasound examinations performed using the standardised limited echo protocol are safe and accurate. The observed concordance with comprehensive ECHO was 78%. This trial is registered with NCT05306730.

Abstract
This case report of a patient with a traumatic head injury provides an example of a systemic toxic reaction to a local anesthetic. Clinical signs of a systemic toxic reaction and hemorrhagic shock may initially be similar: tachycardia, hypotension and unconsciousness. The purpose is thus to remind that even the treatment of a minor injury can develop into a life-threatening condition. When a skin wound is treated using suture under local or regional anesthesia, the annual incidence rate of systemic toxic reactions is 1:3,000 and that of death is 1:30,000.

Randomized comparison of 9-month stent strut coverage of biolimus and everolimus drug-eluting stents assessed by optical coherence tomography in patients with ST-segment elevation myocardial infarction. Long-term (5-years) clinical follow-up (ROBUST trial). Cardiol J 2023:VM/OJS/J/90905. [PMID: 36896638 DOI: 10.5603/cj.a2023.0013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2022] [Revised: 01/01/2023] [Accepted: 01/27/2023] [Indexed: 03/11/2023] Open
Abstract
BACKGROUND The aim of the study was to compare healing (assessed by optical coherence tomography [OCT]) of biolimus A9 (BES) and everolimus drug-eluting stents (EES) at 9-month follow-up in patients with ST-segment elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (pPCI). Nine-month clinical and angiographic data were also compared in both groups as well as clinical data at 5 years of follow-up. METHODS A total of 201 patients with STEMI were enrolled in the study and randomized either to pPCI with BES or EES implantation. All patients were scheduled for 9 months of angiographic and OCT follow-up. RESULTS The rate of major adverse cardiovascular events (MACE) was comparable at 9 months in both groups (5% in BES vs. 6% in the EES group; p = 0.87). Angiographic data were also comparable between both groups. The main finding at 9-month OCT analysis was the greatly reduced extent of mean neointimal area at the cost of a higher proportion of uncovered struts in the BES group (1.3 mm² vs. 0.9 mm²; p = 0.0001 and 15.9% vs. 7.0%; p = 0.0001, respectively). At 5 years of clinical follow-up the rate of MACE was comparable between both groups (16.8% vs. 14.0%, p = 0.74). CONCLUSIONS The study demonstrates a very low rate of MACE and good 9-month stent strut coverage of second-generation BES and EES in patients with STEMI. BES showed greatly reduced extent of mean neointimal hyperplasia area at the cost of a higher proportion of uncovered struts when compared to EES. The rate of MACE was low and comparable in both groups at 5 years.

Abstract
BACKGROUND Unexpected accidental intoxication by uncommon industrial substances is a rare, but challenging and perilous event. To our best knowledge, this is the first reported case of 3,4',5,6'-tetra-tert-butylbiphenyl-2,3'-diol intoxication. CASE REPORT A 20-year-old man was referred to the Department of Emergency Medicine after seven days of nausea and vomiting triggered by drinking mead. Very high doses of 3,4',5,6'-tetra-tert-butylbiphenyl-2,3'-diol were detected in mead, blood, and urine samples. To prove the intoxication, gas chromatography - ion trap was performed. Symptoms of intoxication persisted for two weeks without significant organ damage. The case report illustrates the need for a multistep approach, focused mainly on the analysis of possible sources of intoxication.

Abstract
AIM To evaluate serum levels of selected cytokine receptors in B-cell precursor acute lymphoblastic leukemia (B-ALL) and their association with acknowledged prognostic factors, relapse-free survival (RFS) and overall survival (OS). MATERIALS AND METHODS A total of 42 de novo adult B-ALL patients, 19 BCR/ABL positive, were included in this study. Soluble receptor α for IL-2 (sIL-2Rα), soluble receptor for IL-6 (sIL-6R), soluble receptor for TNF-α type I and II (sTNFR-1, sTNFR-2) and matrix metalloproteinase-9 (MMP-9) were measured by biochip array technology at diagnosis and in complete remission (CR). RESULTS At diagnosis of B-ALL, we found significantly higher levels of sIL-2Rα, sIL-6R, sTNFR-1, sTNFR-2 and significantly lower levels MMP-9 in comparison with CR (p < 0.001 in all cases). BCR/ABL positive patients had higher levels of sIL-2Rα at diagnosis (r = 0.484; p = 0.014). Serum levels of evaluated cytokines were not associated with achievement of CR after one cycle of induction therapy, RFS or OS. CONCLUSION Serum levels of all evaluated cytokines are significantly altered in newly diagnosed B-ALL reflecting activity of the disease. No significant correlations with response to first induction therapy, RFS or OS were found. Further studies with a longer follow-up will be needed.

Abstract
Intravascular optical coherence tomography (IVOCT) is used to assess stent tissue coverage and malapposition in stent evaluation trials. We developed the OCT Image Visualization and Analysis Toolkit for Stent (OCTivat-Stent), for highly automated analysis of IVOCT pullbacks. Algorithms automatically detected the guidewire, lumen boundary, and stent struts; determined the presence of tissue coverage for each strut; and estimated the stent contour for comparison of stent and lumen area. Strut-level tissue thickness, tissue coverage area, and malapposition area were automatically quantified. The software was used to analyze 292 stent pullbacks. The concordance-correlation-coefficients of automatically measured stent and lumen areas and independent manual measurements were 0.97 and 0.99, respectively. Eleven percent of struts were missed by the software and some artifacts were miscalled as struts giving 1% false-positive strut detection. Eighty-two percent of uncovered struts and 99% of covered struts were labeled correctly, as compared to manual analysis. Using the highly automated software, analysis was harmonized, leading to a reduction of inter-observer variability by 30%. With software assistance, analysis time for a full stent analysis was reduced to less than 30 minutes. Application of this software to stent evaluation trials should enable faster, more reliable analysis with improved statistical power for comparing designs.

Abstract
Abstract
Background
Optical coherence tomography (OCT) guidance in primary percutaneous coronary intervention (pPCI) is expected to be safe in short and mid-term follow-up. Long term merits or risks of OCT guidance are unknown.
Purpose
To assess the possible merits of OCT guidance in pPCI in long-term follow-up.
Methods
201 patients with ST-elevation myocardial infarction (STEMI) were enrolled in this study. Patients were randomized either to pPCI alone (angio-guided group, n=96) or to pPCI with OCT guidance (OCT-guided group, n=105) and also either to biolimus A9 or to everolimus-eluting stent implantation. The OCT study was performed after PCI with C7-XRTM intravascular imaging system employing a non-occlusive technique.
Incidence of Device-oriented Composite Endpoints (DoCE) was compared in both study groups. DoCE were defined as composite of definite or possible cardiovascular death, myocardial infarction and target vessel revascularization. The search for DoCE was performed by means of medical check-ups, repeated telephone contacts, analysis of medical records and search in national population registry.
Results
Mean follow-up was 6.5 (6.5–7.1 years). Of these patients, 2 (1.0%) patients died of cardiovascular reason, 4 patients (2%) suffered myocardial infarction and 7 (3.5%) patients underwent target lesion revascularization. In OCT guided group, number of stents per patient was higher (1.4 vs. 1.2, p=0.03). Risk of DoCE was significantly higher in OCT-guided group (7.6% vs. 2.1%, p=0.023).
Event-free survival in study groups
Conclusion
Our data suggest increased risk of adverse events related to OCT guided tailoring of stent implantation performed after pPCI. These findings should be confirmed by further randomised trials with higher statistical power.

Abstract
AIMS To assess the possible merits of optical coherence tomography (OCT) guidance in primary percutaneous coronary intervention (pPCI). METHODS AND RESULTS 201 patients with ST-elevation myocardial infarction (STEMI) were enrolled in this study. Patients were randomized either to pPCI alone (angio-guided group, n=96) or to pPCI with OCT guidance (OCT-guided group, n=105) and also either to biolimus A9 or to everolimus-eluting stent implantation. All patients were scheduled for nine months of follow-up angiography and OCT study. OCT guidance led to post-pPCI optimization in 29% of cases (59% malapposition and 41% dissections). No complications were found related to the OCT study. OCT analysis at nine months showed significantly less in-segment area of stenosis (6% [-11, 19] versus 18% [3, 33]; p=0.0002) in favor of the OCT-guided group. The rate major adverse cardiovascular events were comparable at nine months in both groups (3% in the OCT group versus 2% in the angio-guided group; p=0.87). CONCLUSIONS This study demonstrates the safety of OCT guidance during pPCI. The use of OCT optimized stent deployment in 1/3 of patients in this clinical scenario and significantly reduced in-segment area of stenosis at nine months of follow-up. Whether such improvements in OCT endpoints will have a positive impact on late clinical outcomes, they demand both a larger and longer-term follow-up study.

Abstract
OBJECTIVES The aim of the presented study was to assess plasma glycogen phosphorylase BB (GPBB) concentrations in acute leukemia patients treated with anthracycline containing chemotherapy. BACKGROUND Anthracyclines represent the highest risk for development of cardiotoxicity. GPBB belongs to proposed biomarkers of cardiac injury with a very limited experience in this context. METHODS Totally, 24 adult patients with acute leukemia were enrolled. Plasma GPBB concentrations were measured by ELISA at diagnosis (before chemotherapy), after first chemotherapy with anthracyclines and 6 months after the completion of treatment. The cut-off value for GPBB positivity was 10.00 µg/L as recommended by the manufacturer. RESULTS Before chemotherapy, the mean plasma GPBB concentration was 5.25±3.81 µg/L, increased above the cut-off in 1 patient (4.2 %). After the first chemotherapy, the mean GPBB was 6.61±5.54 µg/L, positive in 7 (29.2 %) patients. Six months after treatment, the mean GPBB was 10.06±11.41 µg/L, positive in 8 (33.3 %) patients. Six months after treatment, we found a significant correlation between elevation in GPBB and diastolic left ventricular dysfunction on echocardiography (r=0.621; p<0.0001). The differences in plasma GPBB between healthy blood donors and patients treated for acute leukemia were statistically significant (p<0.01 in all cases). CONCLUSION Our results suggested that GPBB could become a potential biomarker for detection of acute and chronic cardiotoxicity associated with anthracycline containing chemotherapy. The predictive value for development of treatment-related cardiomyopathy in future is not clear and will be evaluated during the follow-up. Further studies are needed to define the potential role of GPBB and other biomarkers in the assessment of chemotherapy-induced cardiotoxicity (Ref. 21). Text in PDF www.elis.sk.

Abstract
BACKGROUND Cardiotoxicity is a well-known and potentially serious complication of anticancer therapy. Anthracycline-based chemotherapy represents the greatest risk. Early detection of cardiotoxicity is crucial for applying preventive and supportive therapeutic strategies. METHODS AND RESULTS Various methods have been recommended for monitoring of cardiotoxicity. In our conditions, echocardiography and electrocardiography are routinely used. However, this approach shows low sensitivity for the early prediction of cardiomyopathy when the possibilities of appropriate management could still improve the patient's outcome. Recently, biomarkers of cardiac injury have been investigated in the assessment of chemotherapy-induced cardiotoxicity. Cardiospecific biomarkers, such as cardiac troponins, show high diagnostic efficacy in the early subclinical phase of the disease before the clinical onset of cardiomyopathy. Increase in their concentrations correlates with disease severity. As for natriuretic peptides, some studies, including ours, have shown promising results. Definitive evidence of their diagnostic and prognostic role in this context is still lacking and natriuretic peptides have not been routinely used for monitoring of cardiotoxicity in clinical practice. Other perspective biomarkers of cardiotoxicity in oncology are under study, especially heart-type fatty acid-binding protein (H-FABP) and glycogen phosphorylase BB (GPBB). Our studies using GPBB have provided encouraging results. However, the available data are limited and their practical use in this context cannot be recommended until their clinical efficacy is clearly defined. CONCLUSIONS This review covers the current status of biomarkers for the early detection of anthracycline-induced cardiotoxicity. The authors present in brief, their own experience with multiple biomarkers in the detection of cardiotoxicity.

Abstract
OBJECTIVES To assess the relation between initial ECG findings, presence of risk factors, coronary angiography findings, and clinical outcomes in patients with acute myocardial infarction complicated by cardiogenic shock (CS). DESIGN Data from a total of 5572 acute myocardial infarction patients admitted to the four tertiary hospitals during a period of 3 years were analyzed. CS on admission was present in 358 patients (6.4%). They were divided into four groups based on the admission ECG: ST-segment elevation (STEMI), ST-segment depression (STDMI), bundle branch block (BBBMI), and other ECG acute myocardial infarction. RESULTS CS developed most frequently among BBBMI patients (in 12.1% of all BBBMIs, p < 0.001 vs. STEMI), followed by STEMI (6.7%), STDMI (4.4%), and other ECG acute myocardial infarction (2.3%). The risk of CS development was similar in patients with left bundle branch block (LBBB) (13.3%) and right bundle branch block (RBBB) (11.2%). The one-year mortality was highest among RBBBMI patients (66.7%, p < 0.001), followed by LBBBMI (48.6%), other ECG (47.1%), STEMI (41.7%), and STDMI patients (38.1%). CONCLUSIONS RBBB on admission ECG is associated with the highest risk of CS development, frequent left main coronary artery affection, and unsuccessful revascularization. It is also an independent predictor of one-year mortality.

AIMS The current guidelines recommend reperfusion therapy in acute myocardial infarction (AMI) with ST-segment elevation or left bundle branch block (LBBB). Surprisingly, the right bundle branch block (RBBB) is not listed as an indication for reperfusion therapy. This study analysed patients with AMI presenting with RBBB [with or without left anterior hemiblock (LAH) or left posterior hemiblock (LPH)] and compared them with those presenting with LBBB or with other electrocardiographic (ECG) patterns. The aim was to describe angiographic patterns and primary angioplasty use in AMI patients with RBBB. METHODS AND RESULTS A cohort of 6742 patients with AMI admitted to eight participating hospitals was analysed. Baseline clinical characteristics, ECG patterns, coronary angiographic, and echocardiographic data were correlated with the reperfusion therapies used and with in-hospital outcomes. Right bundle branch block was present in 6.3% of AMI patients: 2.8% had RBBB alone, 3.2% had RBBB + LAH, and 0.3% had RBBB + LPH. TIMI flow 0 in the infarct-related artery was present in 51.7% of RBBB patients vs. 39.4% of LBBB patients (P = 0.023). Primary percutaneous coronary intervention (PCI) was performed in 80.1% of RBBB patients vs. 68.3% of LBBB patients (P< 0.001). In-hospital mortality of RBBB patients was similar to LBBB (14.3 vs. 13.1%, P = 0.661). Patients with new or presumably new blocks had the highest (LBBB 15.8% and RBBB 15.4%) incidence of cardiogenic shock from all ECG subgroups. Percutaneous coronary intervention was done more frequently (84.8%) in patients with new or presumably new RBBB when compared with other patients with blocks (old RBBB 66.0%, old LBBB 62.3%, new or presumably new LBBB 73.0%). In-hospital mortality was highest (18.8%) among patients presenting with new or presumably new RBBB, followed by new or presumably new LBBB (13.2%), old LBBB (10.1%), and old RBBB (6.4%). Among 35 patients with acute left main coronary artery occlusion, 26% presented with RBBB (mostly with LAH) on the admission ECG. CONCLUSION Acute myocardial infarction with RBBB is frequently caused by the complete occlusion of the infarct-related artery and is more frequently treated with primary PCI when compared with AMI + LBBB. In-hospital mortality of patients with AMI and RBBB is highest from all ECG presentations of AMI. Restoration of coronary flow by primary PCI may lead to resolution of the conduction delay on the discharge ECG. Right bundle branch block should strongly be considered for listing in future guidelines as a standard indication for reperfusion therapy, in the same way as LBBB.

Abstract
AIM Dimethylsulfoxide (DMSO) is the most frequently used agent for hematopoietic cell (HC) graft cryopreservation. This study aimed to monitor blood pressure and heart rate (HR) during HC graft infusion and assess the impact of cryopreservation with DMSO. METHODS 153 HC graft infusions in 153 consecutive hematological patients (mean age 49.1 -/+ 12.6 years; 80 males) were evaluated. Cryopreservation with DMSO was used in 133 grafts (DMSO group). Twenty grafts were infused directly without cryopreservation (control group). Systolic blood pressure (SBP), diastolic blood pressure (DBP) and HR were measured immediately before and after HC graft infusion. RESULTS SBP and DBP increased significantly after graft infusions cryopreserved with DMSO ( p<0.0001 for SBP; p<0.01 for DBP). Increases (> 10mmHg) in SBP were seen in 42 (31.6%) patients; in DBP in 31 (23.3%) patients. Changes in HR were non-significant in DMSO group. Increases in BP and HR correlated with increasing DMSO dose (p<0.01; p<0.05, respectively). Changes in SBP, DBP and HR were non-significant in control group. CONCLUSION HC graft infusions cryopreserved with DMSO could cause statistically significant increases in SBP and DBP, without changes in HR. These changes were mostly transient and asymptomatic, not requiring therapeutic intervention. However, they might cause complications, especially in patients with preexisting cardiovascular disease, who should be monitored closely during HC transplantation.

Abstract
AIM Monitoring of anthracycline-induced cardiotoxicity with electrocardiography (ECG) and comparing ECG changes with findings on echocardiography (ECHO). METHODS A total of 26 adult acute leukemia patients (mean age 46.2 -/+ 12.4 years, 15 males) treated with 2-6 cycles of anthracycline-based chemotherapy (CT) were studied. Cardiac evaluation was performed at the baseline (before CT), after first CT, after last CT (cumulative anthracycline dose 464.3 -/+ 117.5 mg/m2) and circa 6 months after CT. Time ECG parameters, QRS voltage, presence of repolarization changes, arrhythmias and other abnormalities were evaluated. RESULTS During treatment and follow-up, we found a statistical significant QTc interval prolongation - 414.7 -/+ 16.0 ms (before CT), 419.6 -/+ 21.6 ms (after first CT), 428.0 -/+ 16.2 ms (after last CT) and 430.1 -/+ 18.4 ms (6 months after CT). Significant QTc interval prolongation (> 450 ms) occurred in 3 patients after first CT, in 4 patients after last CT and in 5 patients within 6 months after CT. Significant total QRS voltage lowering in the limb leads (> 1.0 mV versus before CT) occurred in 3 patients after first CT, in 5 patients after last CT and in 6 patients within 6 months after CT. We found a statistically significant correlation between decreased QRS voltage, QTc interval prolongation and left ventricular (LV) dysfunction on ECHO. Repolarization changes associated with oncology treatment were present in 9 patients within 6 months after CT. CONCLUSION Anthracycline treatment is associated with changes in electrical activity of the myocardium. Prolonged QTc interval represents a risk for development of malignant ventricular arrhythmias. Decreased QRS voltage and prolonged QTc interval after anthracycline treatment could correlate with LV dysfunction on ECHO. Further studies will be needed to prove whether these ECG changes could serve as an accessible and non-invasive screening method indicating LV dysfunction after anthracycline treatment.
