Outcomes for patients with implanted cardioverter-defibrillators admitted to the Emergency Department due to electrical shock during the pre-pandemic and COVID-19 era.

BACKGROUND: Implantable cardioverter-defibrillators (ICD)/cardiac resynchronization therapy with defibrillation (CRT-D) recipients may be susceptible to the arrhythmic effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. AIMS: We aimed to evaluate characteristics and outcomes of patients hospitalized for ICD/CRT-D shocks during the pandemic compared to the pre-pandemic period. METHODS: This retrospective study analyzed medical records of patients hospitalized for ICD/CRT-D shock in the pre-pandemic (January 1, 2018-December 31, 2019) and pandemic periods (March 4, 2020-March 3, 2022). Survival data were obtained on October 24, 2022. RESULTS: In total, 198 patients (average age 65.6 years) had 138 pre-pandemic and 124 pandemic visits. Of these patients, 115 were hospitalized during pre-pandemic, 108 during the pandemic, and 25 in both periods. No significant differences were noted in age, sex, number of shocks, or appropriateness of therapy between these periods. During the pandemic, during 14 hospital stays of patients with SARS-CoV-2, 8 (57.1%) received electrical shocks, compared to 12 (10.9%) with negative SARS-CoV-2 tests (P <0.001). The in-hospital mortality rate was 2 of 115 patients hospitalized during the pre-pandemic and 7 of 108 during pandemic periods (4 patients with and 3 without SARS-CoV-2 [P = 0.10]). During the follow-up, there were 66 deaths. Cox regression analysis showed that survival decreased with age and heart failure decompensation in medical history but increased with higher ejection fraction. The pandemic alone was not a survival predictor. However, SARS-CoV-2 infection, older age, and heart failure decompensation in medical history predicted worse outcomes during the pandemic period. CONCLUSIONS: The pandemic did not increase the number of hospital visits due to ICD/CRT-D discharges. SARS-CoV-2 infection predicts increased mortality in patients with ICD/CRT-D shocks.

Shared Decision Making and Cardioneuroablation Allow Discontinuation of Permanent Pacing in Patients with Vagally Mediated Bradycardia.

BACKGROUND: Safe discontinuation of pacemaker therapy for vagally mediated bradycardia is a dilemma. The aim of the study was to present the outcomes of a proposed diagnostic and therapeutic process aimed at discontinuing or not restoring pacemaker therapy (PPM) in patients with vagally mediated bradycardia. METHODS: The study group consisted of two subgroups of patients with suspected vagally mediated bradycardia who were considered to have PPM discontinued or not to restore their PPM if cardioneuroablation (CNA) would successfully treat their bradycardia. A group of 3 patients had just their pacemaker explanted but reimplantation was suggested, and 17 patients had preexisting pacemakers implanted. An invasive electrophysiology study was performed. If EPS was negative, extracardiac vagal nerve stimulation (ECVS) was performed. Then, patients with positive ECVS received CNA. Patients with an implanted pacemaker had it programmed to pace at the lowest possible rate. After the observational period and control EPS including ECVS, redo-CNA was performed if pauses were induced. The decision to explant the pacemaker was obtained based on shared decision making (SDM). RESULTS: After initial clinical and electrophysiological evaluation, 17 patients were deemed eligible for CNA (which was then performed). During the observational period after the initial CNA, all 17 patients were clinically asymptomatic. The subsequent invasive evaluation with ECVS resulted in pause induction in seven (41%) patients, and these patients underwent redo-CNA. Then, SDM resulted in the discontinuation of pacemaker therapy or a decision to not perform pacemaker reimplantation in all the patients after CAN. The pacemaker was explanted in 12 patients post-CNA, while in 2 patients explantation was postponed. During a median follow-up of 18 (IQR: 8-22) months, recurrent syncope did not occur in the CNA recipients. CONCLUSIONS: Pacemaker therapy in patients with vagally mediated bradycardia could be discontinued safely after CNA.

Admissions to the Emergency Department Due to Atrial Fibrillation/Atrial Flutter Incidents during the Third Wave of COVID-19 Pandemic.

(1) Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection increases the risk of atrial fibrillation/flutter (AF/AFL) incident. The study aimed to present the characteristics of admissions to the emergency department (ED) due to AF/AFL incidents during the third COVID-19 pandemic wave. (2) Methods: A retrospective analysis of the medical records of the ED patients: 8399 during 3 months of the second and 11,144 during the 3 months of the third pandemic wave. (3) Results: SARS-CoV-2 positive patients there were 295 (3.5%) during the second wave and 692 (6.2%) during the third wave (p < 0.001). Among patients with SARS-CoV-2 infection, there were 44 (14.9%) patients with known AF/AFL during the second wave and 75 (10.8%) during the third wave, respectively (0.07). There were 116 visits with a diagnosis of AF/AFL incident during the third wave (study group) and 76 visits during the second wave (control group). The SARS-CoV-2 test was positive in 11 (9.5%) visits in the study group and in 1 (1.3%) visit in the control group p = 0.047. During the third wave, the patients with AF/AFL incidents with positive tests were older and more often had new-onset AF/AFL than those with negative tests: 76.3 (13.2) years vs. 71.8 (12.6) years; and 4 (36.4%) patients vs. 7 (7.6%) patients, respectively. (5) Conclusions: During the third pandemic wave, the number of patients with SARS-CoV-2 infection increased in comparison to the second wave. Additionally, among patients with AF/AFL incidents, the percentage of SARS-CoV-2-positive patients increased. During the third wave, the patients with positive tests and AF/AFL incident were older and more often had new-onset AF/AFL than those with AF/AFL incident and negative test which indicate the arrhythmogenic effect at the onset of the disease, especially in the older population.

Implantation of a Leadless Pacemaker after Incomplete Transvenous Lead Extraction in a 90-Year-Old Pacemaker-Dependent Patient.

Transluminal lead extraction (TLE) is a well-established procedure for the removal of damaged or infected pacing systems. Despite its high efficacy, the procedure is associated with significant risks, some of which may contribute to severe life-threatening complications. Herein, we present the case of a 90-year-old female who was 100% pacemaker-dependent (PM-dependent) and had ventricular lead fragmentation after the TLE procedure. In this elderly patient, after taking into account the whole clinical context-age, frailty syndrome, infection, and high peri- and postprocedural risks-we decided on MICRA VR implantation as well as leaving the remains of the ventricular lead in the right heart chambers. A Leadless pacemaker (LP) is an excellent alternative to PM-dependent individuals, in whom implantation of permanent transvenous PM is precluded due to multiple infectious and non-infectious issues.

The arterial stiffness changes in hemodialysis patients with chronic kidney disease: The impact on mortality.

BACKGROUND: Patients with kidney disease suffer from high cardiovascular risk due to classic and disease-specific risk factors. Arterial stiffness is a novel cardiovascular risk factor whose role is yet to be established. High-resolution echo-tracking is a developing method for the assessment of local arterial stiffness. OBJECTIVES: To assess carotid stiffness in patients on long-term hemodialysis (HD) using high-resolution echo-tracking and to analyze the impact of arterial stiffness on mortality in the mid-term follow-up. MATERIAL AND METHODS: Fifty-eight HD patients (28 female (F), 30 male (M)) underwent clinical examination, laboratory tests and carotid stiffness assessment. Local arterial stiffness parameters such as beta stiffness index (ß), Young's modulus (Ep), arterial compliance (AC), and one-point pulse wave velocity (PWVß) were measured both before and after HD, allowing to calculate their change (Δ). The survival of patients was analyzed up to 48 months. The multivariate analysis of survival with the use of Cox proportional hazard stepwise regression was performed to determine the factors significantly correlated with the survival. RESULTS: After 48 months, 33 patients were alive (16 F, 17 M) and 25 patients (12 F, 13 M) died. The deceased group was significantly older (66.5 ±12.3 years compared to 56.6 ±17.8 years), had more pronounced coronary artery disease (percutaneous coronary intervention (PCI) 36% compared to 9%, p < 0.05, respectively). Deceased patients had significantly higher ΔAC than survivors. The results showed that age, history of PCI, left ventricular ejection fraction (LVEF), ΔAC, fasting glucose, serum total protein, sodium level after HD, and potassium level before HD were significantly associated with mortality. CONCLUSIONS: Echo-tracking-based arterial stiffness assessment in patients with chronic kidney disease (CKD) yields the clinical information regarding mid-term mortality risk. A paradoxical increase in AC is among independent risk factors for mid-term mortality in patients undergoing maintenance HD. The proper estimation of the correlations among vascular, hemodynamic and sympathetic-dependent changes in a given patient with kidney failure is complex.

ST-segment depression in atrioventricular nodal reentrant tachycardia: Important finding or just an artifact?

BACKGROUND: The ST segment is component of the QRS-T complex located between the QRS and the T wave. ST segment changes during tachycardia with narrow QRS mainly takes the form of ST segment depression. This phenomenon is often observed in young healthy people for whom an ischemic background is unlikely. MATERIALS AND METHODS: The study included 104 patients (71 women and 33 men) with paroxysmal narrow QRS complex tachycardia. In all patients electrophysiological study was performed and the diagnosis of atrioventricular nodal reentrant tachycardia was established. The arrhythmogenic substrate was then eliminated successfully by subsequent ablation using radiofrequency energy which confirmed the diagnosis, all patients had measured QRS components - QR, RS and RJ during the tachycardia and during the sinusrhythm. All of the measurements were done in lead V5. RESULTS: The difference RJ-QR during tachycardia and sinus rhythm correlated negatively with tachycardia cycle length (R = 0.356, P = .001), first slowly, then rapidly reaching the cycle value of about 300 ms, then it decreases, stabilizing at the cycle level of about 270. By separating the RJ-QR in tachycardia and in the sinus rhythm from the tachycardia cycle, we can see that the correlation described in this point is largely due to the correlation between the heart rate and RJ-QR length in tachycardia. CONCLUSIONS: In patients with atrioventricular nodal reentrant tachycardia, there is a significant ST-segment depression during tachycardia episodes and the degree of this change is related to tachycardia cycle length. The most probable explanation of the ST-segment depression is the overlap of the QRS complex on the preceded T wave. This phenomenon is also influenced by some intrinsic properties of the individual electrocardiogram. It is possible to rule out ischemic origin of the presented ST segment change.

ST-segment depression in atrioventricular nodal reentrant tachycardia: Preliminary results.

BACKGROUND: The ST-segment is part of the electrocardiogram and physiologically, it forms an isoelectric line. The ST-segment depression is often observed in young, healthy people with paroxysmal tachycardia with narrow QRS complexes. In this group of patients, the 'mysterious tachycardia-induced ST-segment depression', 'subendocardial myocardial ischemia' and other not fully understood terms are used to explain this phenomenon. OBJECTIVES: To assess the presence and possible mechanisms of ST-segment depression during atrioventricular nodal reentrant tachycardia (AVNRT) in patients undergoing radiofrequency (RF) ablation of the underlying arrhythmia. MATERIAL AND METHODS: The study included 50 patients (35 women and 15 men) aged about 49 years with clinically relevant paroxysmal narrow QRS complex tachycardia. During electrophysiological study (EPS), all patients had measured QRS components - QR, RS and RJ during the tachycardia and during the sinus rhythm. All of the measurements were done in lead V5. RESULTS: There was a statistically significant difference in cycle length during sinus rhythm and tachycardia (707.0 ±137.8 ms compared to 327.5 ±29.1 ms, p = 0.000), the RJ component (0.819 ±0.381 mV compared to 0.878 ±0.376 mV, p = 0.003) and the difference RJ-QR (0.081 ±0.083 mV compared to 0.163 ±0.108 mV, p = 0.000). The differences in RS and QR components during sinus rhythm and tachycardia did not reach the statistical significance. The difference RJ-QR during tachycardia correlated negatively with tachycardia cycle length (R = -0.39, p = 0.0049). The tachycardia cycle length correlated positively with the age of the studied patients (R = 0.28, p = 0.043). CONCLUSION: In patients with AVNRT, there is a ST-segment depression during the episodes of tachycardia and the degree of this change is related to tachycardia cycle length. The most probable explanation of the ST-segment depression is the overlap of the QRS complex on the preceded T wave. Some intrinsic properties of individual electrocardiogram (ECG) also influence this phenomenon. The ischemic origin of the presented ST-segment change can be excluded.

Simple demographic characteristics and laboratory findings on admission may predict in-hospital mortality in patients with SARS-CoV-2 infection: development and validation of the covid-19 score.

BACKGROUND: Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) constitutes a major health burden worldwide due to high mortality rates and hospital bed shortages. SARS-CoV-2 infection is associated with several laboratory abnormalities. We aimed to develop and validate a risk score based on simple demographic and laboratory data that could be used on admission in patients with SARS-CoV-2 infection to predict in-hospital mortality. METHODS: Three cohorts of patients from different hospitals were studied consecutively (developing, validation, and prospective cohorts). The following demographic and laboratory data were obtained from medical records: sex, age, hemoglobin, mean corpuscular volume (MCV), platelets, leukocytes, sodium, potassium, creatinine, and C-reactive protein (CRP). For each variable, classification and regression tree analysis were used to establish the cut-off point(s) associated with in-hospital mortality outcome based on data from developing cohort and before they were used for analysis in the validation and prospective cohort. The covid-19 score was calculated as a sum of cut-off points associated with mortality outcome. RESULTS: The developing, validation, and prospective cohorts included 129, 239, and 497 patients, respectively (median age, 71, 67, and 70 years, respectively). The following cut of points associated with in-hospital mortality: age > 56 years, male sex, hemoglobin < 10.55 g/dL, MCV > 92.9 fL, leukocyte count > 9.635 or < 2.64 103/µL, platelet count, < 81.49 or > 315.5 103/µL, CRP > 51.14 mg/dL, creatinine > 1.115 mg/dL, sodium < 134.7 or > 145.4 mEq/L, and potassium < 3.65 or > 6.255 mEq/L. The AUC of the covid-19 score for predicting in-hospital mortality was 0.89 (0.84-0.95), 0.850 (0.75-0.88), and 0.773 (0.731-0.816) in the developing, validation, and prospective cohorts, respectively (P < 0.001The mortality of the prospective cohort stratified on the basis of the covid-19 score was as follows: 0-2 points,4.2%; 3 points, 15%; 4 points, 29%; 5 points, 38.2%; 6 and more points, 60%. CONCLUSION: The covid-19 score based on simple demographic and laboratory parameters may become an easy-to-use, widely accessible, and objective tool for predicting mortality in hospitalized patients with SARS-CoV-2 infection.

The Impact of COVID-19 on Admissions and Management of Patients with Atrial Fibrillation Episodes in the Emergency Department.

BACKGROUND: During the COVID-19 pandemic, the number of admissions to the emergency department (ED) due to a primary diagnosis of atrial fibrillation (AF) has decreased when compared to pre-pandemic times. The principal aim of the study was to assess the frequency of SARS-CoV-2 infections and sinus rhythm restoration among patients who arrived at the ED with AF. Secondary aims included determining whether patients arriving at the ED principally due to AF delayed their presentations and whether the frequency of successful cardioversion for AF was decreased during the pandemic period. MATERIALS AND METHODS: A retrospective analysis of medical records of patients admitted to two hospital EDs due to AF during July-December 2019 (pre-pandemic period) versus July-December 2020 (pandemic period) was performed. RESULTS: During the study periods, 601 ED visits by 497 patients were made due to the primary diagnosis of AF. The patients were aged 71.2+/-13.5 years and 51.3% were male. The duration of an AF episode before the ED admission was 10 h (4.5-30 h) during the pandemic period vs. 5 h (3-24 h) during the non-pandemic period (p = 0.001). A shorter duration of the AF episode before ED admission was associated with the successful restoration of the sinus rhythm. During the pandemic period, among patients with short-lasting AF who were not treated with Phenazolinum, the restoration of the sinus rhythm was more frequent in the Copernicus Memorial Hospital than in the University Hospital (p = 0.026). A positive SARS-CoV-2 test was found in 5 (1%) patients, while 2 other patients (0.5%) had a prior diagnosis of COVID-19 disease noted in their medical history. CONCLUSIONS: 1. The number of AF episodes treated in these two EDs was lower during the pandemic than non-pandemic period. 2. The patients with AF appeared at the ED later after AF onset in the pandemic period. 3. Successful cardioversion of atrial fibrillation was more frequent during the pre-pandemic period in one of the two hospitals. 4. A difference of approaches to the treatment of short-lasting AF episodes between EDs during the pandemic period may exist between these two EDs. 5. The patients with SARS-CoV-2 infection during the second wave of the COVID-19 pandemic constituted a small percentage of the patients admitted to EDs due to an AF episode.

The importance of the longest R-R interval on 24-hour electrocardiography for mortality prediction in patients with atrial fibrillation.

BACKGROUND: Heart rate control in atrial fibrillation (AF) is typically assessed by 24­hour electrocardiography (ECG). There are scarce data on the use of 24­hour ECG parameters to predict mortality in patients with AF. AIMS: We aimed to identify 24­hour ECG parameters that predict mortality in patients with AF. METHODS: We enrolled 280 ambulatory patients (mean [SD] age, 72 [8.7] years; 57.9% men) with permanent or persistent AF. Data on mortality and pacemaker or defibrillator implantation during follow­up were collected. Predictors of mortality were assessed using the Cox proportional hazards model and C statistic. RESULTS: Compared with survivors, 78 patients (28%) who died were older, more often had comorbidities, left bundle branch block (LBBB), reduced left ventricular ejection fraction, lower maximum heart rate, higher number of ventricular extrasystoles, and the longest R­R interval below 2 seconds. Univariate analysis showed higher mortality in patients with the longest R­R intervals below 2 seconds compared with those with R­R intervals of 2 seconds or longer (P <0.001). Independent mortality predictors in the regression model included older age, renal failure, history of coronary intervention, chronic obstructive pulmonary disease, LBBB, and a high number (≥770) or absence of R­R intervals of at least 2 seconds. The area under the curve for mortality prediction increased after including ECG parameters (0.748; 95% CI, 0.686-0.81; vs 0.688; 95% CI, 0.618-0.758; P = 0.02). CONCLUSIONS: A high number of R­R intervals longer than 2 seconds or their absence on 24­hour ECG may predict mortality in patients with AF.

Glasgow Coma Scale score of more than four on admission predicts in-hospital survival in patients after out-of-hospital cardiac arrest.

AIM: The aim of the study was to assess the usefulness of the Glasgow Coma Scale (GCS) score assessed by EMS team in predicting survival to hospital discharge in patients after out-of-hospital cardiac arrest (OHCA). METHODS: Silesian Registry of OHCA (SIL-OHCA) is a prospective, population-based regional registry of OHCAs. All cases of OHCAs between the 1st of January 2018 and the 31st of December 2018 were included. Data were collected by EMS using a paper-based, Utstein-style form. OHCA patients aged ≥18 years, with CPR attempted or continued by EMS, who survived to hospital admission, were included in the current analysis. Patients who did not achieve return of spontaneous circulation (ROSC) in the field, with missing data on GCS after ROSC or survival status at discharge were excluded from the study. RESULTS: Two hundred eighteen patients with OHCA, who achieved ROSC, were included in the present analysis. ROC analysis revealed GCS = 4 as a cut-off value in predicting survival to discharge (AUC 0.735; 95%CI 0.655-0.816; p < 0.001). Variables significantly associated with in-hospital survival were young age, short response time, witnessed event, previous myocardial infarction, chest pain before OHCA, initial shockable rhythm, coronary angiography, and GCS > 4. On the other hand, epinephrine administration, intubation, the need for dispatching two ambulances, and/or a physician-staffed ambulance were associated with a worse prognosis. Multivariable logistic regression analysis revealed GCS > 4 as an independent predictor of in-hospital survival after OHCA (OR of 6.4; 95% CI 2.0-20.3; p < 0.0001). Other independent predictors of survival were the lack of epinephrine administration, previous myocardial infarction, coronary angiography, and the patient's age. CONCLUSION: The survival to hospital discharge after OHCA could be predicted by the GCS score on hospital admission.

Epidemiology, management, and survival rate of out-of-hospital cardiac arrest in Upper Silesia, Poland: an Utstein-style report.

INTRODUCTION: Despite the growing number of studies on the epidemiology of out-of-hospital cardiac arrest (OHCA) in Poland, this issue has not been sufficiently studied. Notably, there has been a lack of uniform Utstein-style data reporting. AIM: To evaluate the epidemiology of OHCA, patient characteristics, the laypeople and emergency medical service (EMS) response to cardiac arrest, and outcomes of OHCA patients, based on a prospective registry encompassing a population of 2.7 million Poles. MATERIAL AND METHODS: Consecutive, adult, EMS-treated OHCA cases in 2018 were analyzed. Prehospital data were collected using case report forms by EMS. Information on in-hospital procedures and outcomes was based on data from the public payer of health care services. Multivariable logistic regression analysis was performed to find independent predictors of survival to discharge. RESULTS: A total of 1392 patients were included. Most OHCA occurred at home (74.7%). In 66.8% of OHCA cases, the cardiac arrest was witnessed by bystanders and in another 20.4% by EMS. Laypeople performed cardiopulmonary resuscitation (CPR) in 54.4% of non-EMS-witnessed events, and an automated external defibrillator (AED) was used in 4.6% of patients who received bystander CPR. Finally, 30.7% of all patients were transported to the hospital, and 9.2% survived to hospital discharge. Epinephrine administration, unwitnessed OHCA, longer response time, older age, and initial non-shockable rhythm were independently associated with lower survival to discharge. CONCLUSIONS: The prognosis of OHCA patients in Poland is poor. There is still room for improvement in increasing the prevalence of bystander CPR and AED use before EMS arrival.

Out-of-hospital cardiac arrest in dialysis patients.

PURPOSE: The aim of the study was to assess whether a history of dialysis is related to cardiopulmonary resuscitation (CPR) attempts and survival to hospital admission in patients with out-of-hospital cardiac arrest (OHCA). METHODS: The databases of the POL-OHCA registry and of emergency medical calls in the Command Support System of the State of Emergency Medicine (CSS) were searched to identify patients with OHCA and a history of dialysis. A total of 264 dialysis patient with OHCA were found: 126 were dead on arrival of emergency medical services (EMS), and 138 had OHCA with CPR attempts. Data from the POL-OHCA registry for patients with CPR attempts, including age, sex, place of residence, first recorded rhythm, defibrillation during CPR, and priority dispatch codes, were collected and compared between patients with and without dialysis. RESULTS: CPR attempts by EMS were undertaken in 138 dialyzed patients (52.3%). The analysis of POL-OHCA data revealed no differences in age, sex, place of residence, first recorded rhythm, and priority dispatch codes between patients with and without dialysis. Defibrillation was less frequent in dialysis patients (P = 0.04). A stepwise logistic regression analysis revealed no association between survival to hospital admission and a history of hemodialysis (odds ratio = 1.12; 95% CI 0.74-1.70, P = 0.60). CONCLUSIONS: A history of dialysis in patients with OHCA does not affect the rate of CPR attempts by EMS or a short-term outcome in comparison with patients without dialysis. Defibrillation during CPR is less common in patients on dialysis than in those without.

RETROSPECTIVE ANALYSIS OF INTERVENTIONS PERFORMED BY EMERGENCY MEDICAL TEAMS IN POLAND BEFORE AND DURING THE SARS COV-2 PANDEMIC.

OBJECTIVE: Introduction: The SARS-CoV-2 virus was recognized in December 2019 in China. From that moment it has quickly spread around the whole world. It causes COVID-19 disease manifested by breathlessness, coughing and high temperature. The COVID-19 pandemic has become a great challenge for humanity. The aim: To analyze interventions of emergency medical teams during the SAR-CoV-2 pandemic, and to compare obtained data with the same periods in 2018-2019. PATIENTS AND METHODS: Material and methods: The study retrospectively analyzed interventions of emergency medical teams in the period from 15.03 to 15.05 in 2018 - 2020. 1,479,530 interventions of emergency medical teams were included in the study. The number of interventions, reasons for calls, and diagnoses made by heads of the emergency medical teams during the SARS-CoV-2 pandemic were compared to the same period in 2018-2019. RESULTS: Results: Authors observed the decline in the number of interventions performed by emergency medical teams during the pandemic in relation to earlier years by approximately 25%. The big decline concerned interventions that were the reason for calls to public places, such as "traffic accident" and "collapse". In the case of diagnoses made by the head of the emergency medical team, the diagnoses regarding stroke or sudden cardiac arrest remained at the similar level. Others showed a marked decline. CONCLUSION: Conclusions: Reduced social activity contributed to a reduced number of interventions by emergency medical teams in public places. The societal fear of the unknown also contributed to the decrease in the number of interventions performed by emergency medical teams. People began to avoid contact with other people.

Prognosis of Syncope With Head Injury: a Tertiary Center Perspective.

Aim: Head injury is the most common trauma occurring in syncope. We aimed to assess whether syncope as cause of head-trauma affects short-and long-term prognosis. Methods: From a database retrospective analysis of 97,014 individuals attending Emergency Department (ED), we selected data of patients with traumatic head injury including age, gender, injury mechanism, brain imaging, multiple traumas, bone fracture, intracranial bleeding, and mortality. Mean follow-up was 6.4 ± 1.8 years. Outcome data were obtained from a digital national population register. The study population included 3,470 ED head injury patients: 117 of them (50.0 ± 23.6 years, 42.7% men) reported syncope as cause of head trauma and 3,315 (32.2 ± 21.1 years, 68.5% men) without syncope preceding head trauma. Results: Thirty-day mortality was low and similar in traumatic head injury with or without syncope. One year and long-term all-cause mortality were both significantly higher in syncopal vs. non-syncopal traumatic head injury (11.1 vs. 2.8% and 32 vs. 10.2%, respectively; both p < 0.001). In adjusted logistic regression analysis, death between 121st-day and 1 year in patients with head-trauma was associated with male gender [odds ratio (OR): 6.48; 95% CI: 2.59-16.25], advancing age (per year) (OR 1.09; 95% CI 1.07-1.11), Glasgow Coma Scale < 13 (OR: 6.18; 95% CI:1.68-22.8), bone fracture (OR 4.72; 95% CI 2.13-10.5), and syncope (OR 3.70; 95% CI: 1;48-9.31). In multivariable Cox regression analysis, syncope was one of the strongest independent predictors of long-term all-cause death (hazard ratio: 1.95; 95% CI 1.37-2.78). Conclusion: In patients with head trauma, history of syncope preceding injury does not increase 30-day all-cause mortality but portends increased 1 year and long-term mortality.

The Global Longitudinal Strain in Renal Transplant Recipients and Immunosuppressive Regimen.

BACKGROUND: Echocardiographic global longitudinal strain (GLS) has recently been considered as a more effective assessment than the ejection fraction (EF) in detecting subtle changes of left ventricular (LV) systolic function. The aim of the study is to compare GLS in renal transplant recipients (RTrs) with preserved LVEF, depending on the recipient's immunosuppressive regimen. The impaired GLS was considered to be > -18%. METHODS: A total of 84 RTrs were divided into 2 groups depending on immunosuppressive regimen: group 1, which included 32 patients (aged 62.3 ± 7.5) receiving mammalian target of rapamycin inhibitors, and group 2, which included 52 patients (aged 58.9 ± 13.9 treated with calcineurin inhibitors. In all patients, echocardiography was performed, including calculation of GLS, and laboratory and clinical markers of cardiovascular risk were assessed. RESULTS: The frequency of men was significantly higher in group 1 (P = .01). There were no differences between the groups in age, body mass index, frequency of diabetes, hypertension, time of hemodialysis (HD) before kidney transplantation (KTx), time after KTx, concentration of cholesterol and creatinine, echocardiographic linear parameters, and LV mass. The estimated glomerular filtration rate and triglyceride concentration were significantly higher in group 1. The mean value of GLS was similar in both groups (-19.8 [-3.5] vs -18.9 [-3.0]; P = .22). The multivariate logistic regression analysis revealed that duration of HD > 26 months is associated with GLS ≥ -18% (odds ratio 2.95, 95% CI 1.08-7.99, P = .03) CONCLUSIONS: The frequency of impaired GLS in RTr was similar regardless of the type of the immunosuppressive regimen. The impaired GLS was associated with duration of HD before KTx.
