Outbreak of Acute Fulminant Myocarditis in Children in Campania Region, Italy: A Case Series

Acute fulminant myocarditis is a rare event in children, accounting for about 10% of all cases of acute myocarditis. Its lack of specific onset patterns and unpredictable evolution make diagnosis and prompt treatment challenging. We observed six cases of fulminant myocarditis admitted to our Pediatric Emergency Unit (Campania region, Sothern Italy) within a very short timeframe (50 days, from July to September 2024). Three of them died, and two are still under treatment in a Pediatric Cardiologic Intensive Care Unit in critical condition. In only one case, cardiac function improved. The described cases were not geographically linked, belonging to different areas of Southern Italy. No common etiological agent was found. Given the relatively low incidence of the condition, the occurrence of six pediatric myocarditis within approximately two months should be considered exceptional. Careful monitoring of further cases in the next few months should be warranted.

Analysis of Compliance with Proper Nutrition Principles in Patients with a History of Myocardial Infarction.

Adherence to dietary recommendations and the implementation of appropriate dietary habits after myocardial infarction (MI) can significantly improve health and reduce mortality from cardiac causes. The aim of this study was to analyse the adherence of patients with a history of MI to a healthy diet, which is one of the primary methods of cardiovascular disease (CVD) prevention. Following a proper diet involves limiting the consumption of saturated fats, salt, alcohol, and simple sugars. It is recommended to follow the Mediterranean diet, which is based on whole grains, fruits, vegetables, and fish. This study involved 120 patients hospitalised in the Invasive Cardiology and Cardiac Intensive Care Unit at the Independent Public Voivodship Hospital in Szczecin from August to December 2019. A self-designed questionnaire and the Questionnaire of Eating Behaviour (QEB) were used. The majority of respondents were hospitalised for a first-time MI (88.33%), and 65% of them reported adherence to the recommendations. The vast majority (78.33%) considered their diet good, with 50.83% of the respondents eating four meals a day and never eating fast food (49.17%). The analysis showed that although the respondents' diets did not contain many unhealthy foods, they did not consume enough vegetables, fruits, fish, nuts, or fibre, which have a protective effect, lowering the risk of cardiovascular diseases and death. Furthermore, patients with a better education had a higher level of knowledge. Respondents' knowledge of proper post-MI nutrition was sufficient, and their index of unhealthy diets was low, but they still made dietary mistakes and did not consume enough health-protective foods. These results indicate a need for further education.

Incidence of Acute Kidney Injury and Mortality Post Successful Cardiac Surgery in a Kashmiri Cohort: A Prospective Comparison of the RIFLE and KDIGO Criteria.

Background and objectives In critically ill patients, acute kidney injury (AKI) influences mortality and morbidity. Few studies have looked at mortality and the frequency of AKI following successful heart and thoracic operations. The current study investigates the association between AKI and mortality rates among patients undergoing post-cardiac surgery care within the Cardiology & Cardio Vascular Thoracic Surgery (CVTS) Intensive Care Unit (ICU). Methodology In this prospective research, 124 patients who underwent successful cardiovascular and thoracic procedures between June 2022 and June 2023 were admitted to the CVTS ICU. To determine mortality, we contrasted the two scoring methods, Kidney Disease-Improving Global Outcomes (KDIGO) and Risk, Injury, Failure, Loss of kidney function, and End-stage kidney disease (RIFLE). Results Based on the KDIGO criteria, AKI was identified in 37.90% (n = 47) of the patients, and it was identified in 15.32% (n = 19) of the patients utilizing RIFLE. Notably, patients diagnosed with AKI using either the RIFLE criteria or KDIGO criteria exhibited considerably higher mortality rates (p< 0.001). Receiver operating characteristic (ROC) analysis demonstrated the effectiveness of both scoring systems in identifying mortality (area under the ROC curve for RIFLE = 0.224 and KDIGO = 0.150). Conclusion Post-cardiac surgery, AKI escalates both mortality and morbidity rates. Despite KDIGO detecting more severe renal injury and mortality, both scoring systems exhibit comparable sensitivity and specificity in predicting death among patients undergoing various cardiovascular and thoracic procedures.

Cardiology intensive care unit nurse in italy: definition of advanced competences. IN-CORE study

Abstract Background/Introduction Since the establishment of the Cardiology Intensive Care Units to date, there have been many scientific and technological progresses that have involved not only the pathways of diagnosis and treatment of patients in this specialist area, but also the specialist competencies that nurses must acquire in order to work in these settings. The epidemiological picture and incidence of comorbidities suggest the care of patients requiring intensive and specialised care, with the use of high technology and circulatory support systems, changing the usual setting of a cardiology intensive care unit to a high-intensity cardiology intensive care unit. To date, a few studies have been described in the literature that have mapped the competences of the cardiology intensive care unit nurse, but the heterogeneity of training education at a European level has not yet made a reference framework for this specialist area generalisable. (Endacott R., et al. 2022). In Italy, there are no specific postgraduate courses focused on specialist cardiac intensive care skills development for nurses. To develop such courses, content incorporating appropriate competencies is required and this study was designed to meet this. Purpose To identify the core competencies of nurses working in High-intensity cardiology intensive care units (ICUs) in Italy to develop national competence framework. Methods A three-round e-Delphi study was conducted with a group of 30 experienced cardiac intensive care unit nurses; 28 completed all three rounds. The first round asked each participant to write down five competences, which they were asked to prioritize in the second round. In the third round, they were asked to prioritize again, considering the scores made in the second round. The final list of competencies was the one that achieved a greater than 70% agreement among the participants. Results We identified 12 core competencies that include a few competence areas, including high-tech care, emergency management, teamwork, and critical decision-making. Only slight differences emerged among the panel of experts regarding the priority given to certain core competencies, such as ECG reading, emergency management and technical and practical skills in the intensive care area. Conclusions This is the first study in Italy to identify the core and advanced competencies of nurses working in high level cardiac intensive care units. This study provides an important basis for the development of postgraduate educational programme and a framework for the definition of national standards to be implemented in clinical practice.

Cardiology department versus intensive care unit admission after successful uncomplicated transcatheter aortic valve replacement (TAVR)

BackgroundMost patients after transcatheter aortic valve replacement (TAVR) are admitted directly to the cardiac intensive care unit (CICU) despite low complication rates. Reducing unnecessary CICU hospitalization reduces healthcare costs. This study aimed to compare the outcomes between patients admitted directly to the cardiology department (CD) and those admitted to CICU based on prespecified protocols. MethodsHistorical cohort study of all patients who underwent TAVR and were admitted directly to the CD according to a prespecified protocol (uncomplicated procedure, hemodynamically stable, without new conduction abnormalities) in 2017–2018, and the same number of patients meeting the same criteria who were admitted to the CICU in 2015–2016 before direct CD admission was initiated. Pacemaker implantation during the procedure was not considered a new conduction abnormality. In-hospital outcomes and 30-day post-discharge outcomes were compared. ResultsOverall, 260 patients (130 CICU + 130 CD) were included in the study. There was no in-hospital mortality in either group, and the post-procedure length of stay was shorter for patients admitted to CD (median and IQR: 2, 2–4 vs. 4, 3–5 days, p <0.001). There was no significant difference in 30-day emergency department visits between groups (CICU:13.9% vs. CD:16.2%, p = 0.602), rehospitalization rate (9.3%) was the same in both groups, and one patient from the CICU group died. Similar results were observed in multivariable analysis and after matching. ConclusionDirect admission to the CD after TAVR, according to the proposed criteria, may be considered as a safe and less expensive alternative for stable patients after an uncomplicated TAVR procedure.

Identification and characterization of critical values in therapeutic drug monitoring: a retrospective analysis

Therapeutic drug monitoring (TDM) is a crucial clinical practice that improves pharmacological effectiveness and prevent severe drug-related adverse events. Timely reporting and intervention of critical values during TDM are essential for patient safety. In this study, we retrospectively analyzed the laboratory data to provide an overview of the incidence, distribution pattern and biochemical correlates of critical values during TDM. A total of 19,110 samples were tested for nine drug concentrations between January 1, 2019, and December 31, 2020. Of these, 241 critical values were identified in 165 patients. The most common critical values were vancomycin trough (63.4%), followed by tacrolimus trough (16.9%) and digoxin (15.2%). The primary sources of drug critical values were the department of general intensive care unit (ICU), cardiology, and surgery ICU. At baseline or the time of critical value, significant differences were found between the vancomycin, digoxin, and tacrolimus groups in terms of blood urea nitrogen (BUN), creatinine, N-terminal Pro-B-Type Natriuretic Peptide (NT-proBNP), and lymphocyte percentage, P < 0.05. Therefore, it is important to prioritize and closely monitor drug concentrations to reduce laboratory critical values during TDM.

ACUTE MYOCARDIAL INFARCTION WITH “ST” SEGMENT ELEVATION IN SOUTHERN MARCHE: INTRA AND POST–HOSPITAL PROCESS INDICATORS IN THE APPLICATION OF THE UNIFIED PDTA “RETE STEMI” AST OF ASCOLI PICENO AND FERMO. LONGITUDINAL OBSERVATIONAL CLINICAL STUDY

Abstract Background SCAs (Acute Coronary Syndromes) are one of the most frequent cardiovascular diseases, among which STEMI is certainly the most relevant in terms of short and long–term prognosis. The latest ESC Guidelines about ACS–STEMI indicate some key elements in terms of diagnosis and treatment, from first contact to cardiological rehabilitation. Objective Detect the number of SCA–STEMIs managed in the AST of Ascoli Piceno, along with intra and post–hospital process indicators provided in the PDTA of the “RETE STEMI” issued by the Marche Region specifically in AST of Ascoli Piceno. MATERIALS &amp; METHODS An observational, longitudinal, monocentric, not–for–profit clinical study without diagnostic–therapeutic interventions was designed. The data collection started on 01/11/2022 and ended on 30/06/2023, at “Madonna del Soccorso” Hospital of San Benedetto del Tronto and “Mazzoni” Hospital of Ascoli Piceno in Cardiological Intensive Care Units (UTIC). Useful data for this study were acquired every month, consulting the folders of each patient diagnosed with “SCA–STEMI”, and then, reported in an Excel sheet, they were processed with different mathematical and statistical functions, including frequency, percentage, arithmetic average and standard deviation, and later used to design tables and graphs. All the data have been aggregated in full compliance with current legislation on the protection of patient privacy. Results The most significant results are related to the time between the first medical contact and the’ starting of the PPCI procedure, with an average time detected of 110 minutes. Another very important result is the number of patients sent to a post–acute cardiological rehabilitation program (PCRP): from the present study it appears that only the 1% of the entire sample was sent to a PCRP. Finally, other indicators considered in relation to the PDTA appear to be in line with the current Guidelines. Conclusions The present study highlights the aspects of the STEMI PDTA of the Marche Region which could be improved, namely reducing FCM–Wire crossing time and sending patients to a cardiological rehabilitation program, also by implementing the figure of the nurse specialized in the critical and cardiological area.

THE CONUNDRUM OF DRUG INTERACTIONS AND HOLTER MONITORING: LAMIN GENE MUTATION DISCOVERED BY A TORSADE DE POINTES EPISODE FOLLOWED BY OUT–OF–THE–HOSPITAL RESUSCITATION

Abstract The prolongation of the QTc interval on the electrocardiogram is known to be associated with an increased risk of developing life–threatening ventricular arrhythmias such as torsades de pointes (TdP). QTc values exceeding 500 ms can double or even triple the risk of TdP. Many drugs, including amiodarone and some SSRI antidepressants like paroxetine, can prolong the QTc interval. A 57–year–old patient experienced cardiac arrest during an overnight Holter recording prescribed to exclude brady–tachy syndrome in the presence of persistent atrial fibrillation. ECG ambulatory monitoring revealed significant bradycardia with the onset of idioventricular rhythm, followed by TdP triggered by premature ventricular contractions, subsequently degenerating into ventricular fibrillation. The patient was resuscitated by family members and later by emergency medical personnel using 3 DC shocks, leading to the restoration of spontaneous circulation. The patient was transferred to the cardiology intensive care unit where a coronary angiography showed normal results. Blood tests indicated low potassium levels (3.3 mEq/L), with a moderately reduced left ventricular ejection fraction at 45%. The patient was discharged after ICD implantation and during the diagnostic follow–up the genetic testings for long QT syndrome were negative, but showed a mutation of the LMNA lamin A/C gene. During the two months previous to hospital admission, the patient had complained of fatigue in the presence of atrial fibrillation with a low ventricular response. Nonetheless, she had been prescribed oral amiodarone to optimize the chances of successful electrical cardioversion, in combination with paroxetine that the patient was already taking at home. The combination of these two drugs and the patient‘s idiopathic bradycardia contributed to a marked prolongation of the QT interval, leading to TdP degenerated into ventricular fibrillation. This case, notable for the prolonged recording of ventricular fibrillation and subsequent resuscitation chest compressions during a Holter monitoring, suggests caution in the use of antiarrhythmic drugs unless strongly indicated in the presence of potentially ominous drug interactions. It is encouraging to note how the widespread adoption of cardiopulmonary resuscitation culture has enabled individuals who might not have otherwise received medical attention to be effectively resuscitated.

What if youth is not enough? Acute coronary syndrome in young patients

Abstract Funding Acknowledgements None. Background Acute Coronary Syndromes (ACS) are the leading cause of mortality in Spain. Further research is needed in order to know risk factors and outcomes in young patients so that medicians could optimize their management and prevention. Purpose Identifying risk factors, clinical characteristics and short-term outcomes in Acute Coronary Syndrome in patients aged 40 and under. Methods A retrospective analysis of patients under 40 years of age who were admitted for ACS, out of 3,859 ACS admissions in Cardiology Intensive Care Unit (CICU) in our hospital between 2012 and 2022. Results 67 patients (1.73%) were included, most of them were males (83.6%). Baseline characteristics are summarized in Table 1. 77.6% had hypertension (HTA), 22.4% had diabetes (DM) and 34.3% had dyslipidemia (DLP). 79.1% were smokers, 9.1% had a history of alcoholism and 29.9% were cocaine users. None of them had a history of stroke, atrial fibrillation (AF). Only 3% had ischemic heart disease. 68.7% of them were ST-elevation myocardial infarction (STEMI) and inferior STEMI was the most common (38.7%). In anterior STEMI (22 patients), 15 had a severe lesion in the mid-left anterior descending artery (LAD), and 6 in the left main stem (LM). Single-vessel disease was the most common (70.8%), with 3-vessel disease in 4.6%. 75.8% received percutaneous coronary intervention (PCI), and 3% underwent bypass surgery. During admission, 10.5% progressed to Killip class III-IV. The ICU mortality was 1.5%. 9% received vasoactive drugs and 4.5% were intubated. Non-invasive ventilation was used in 3% and high-flow nasal cannula oxygen therapy in 5.3%. 3% received intra-aortic balloon pump support and 1.5% underwent dialysis or ultrafiltration. 4.5% received an implantable cardioverter-defibrillator (ICD), although none of them developed bundle branch block or atrioventricular node block, nor AF. After discharge, 11.1% had recurrent ACS, and up to 5.6% underwent PCI again, with a mortality rate of 11.8%. Conclusion Approximately 2% of ACS occur in people younger than 40 years of age. Substance abuse (smoking, cocaine and alcoholism) becomes more prevalent in this group. Prevalence of comorbidities (such as diabetes and nephropathy) are lower, making them less prone to short-term heart failure. However, they are more susceptible to recurrent ischemic events. There is a high incidence of inferior STEMI and LM-STEMI. For these reasons, medicians may need to find out a substance abuse in this group and further research into other risk factors, such as coronary disease family history.Basal characteristicsClinical evolution of patients

Early prediction of chronic heart disease with recursive feature elimination and supervised learning techniques

&lt;p&gt;Chronic heart disease (CHD) is a common complication among patients suffering in the cardiological intensive care unit, often resulting in poor prognosis and high mortality. Early prediction of CHD can reduce mortality by preventing the severity of the disease. This study evaluated the efficacy of on recursive feature elimination for predicting CHD using supervised learning techniques for predicting CHD. The study employed 1190 Cleveland Hungarian CHD dataset. Different supervised learning techniques (support vector machine, decision tree, k-nearest neighbor, Naive Bayes, stochastic gradient descent, adaptive boosting, and multilayer perceptron) were used to study the efficacy of the recursive feature elimination. Chest pain type, sex, blood sugar level, angina, depression, and slope were associated with CHD occurrence. The accuracy of the K-nearest neighbor and decision tree model was 89.91% for the feature-selected dataset indicating good predictive ability. Ultimately, the support vector machine and logistic regression with the selected features exhibited good discriminatory ability for early prediction of CHD. Thus, the recursive feature elimination is a good approach to develop a a model with higher accuracy to predict CHD.&lt;/p&gt;

Effectiveness of Primary Coronary Intervention for Patients With Delayed ST-Segment Elevation Myocardial Infarction: Insights from Moroccan Cardiology Intensive Care Units

The benefits of myocardial revascularization in ST-segment elevation acute coronary syndrome after 12 to 24 hours from symptom onset remain a topic of debate, especially in patients who are stable and asymptomatic. We analyzed the benefit of late revascularization by primary coronary intervention in patients admitted to Moroccan cardiac intensive care units (CICUs) with ST-segment elevation myocardial infarction after 12 hours of symptom onset. We included a total of 406 patients who met the inclusion criteria: 262 patients in the invasive strategy group and 144 patients in the conservative strategy group. A total of 74.6% were men, and 25.4% were women. For the primary outcome, 46 all-cause deaths were observed at 1 year, with 33 patients in the conservative strategy arm and 13 patients in the invasive strategy group, with a significant difference between the 2 groups (p <0.001). For secondary outcomes, there was no difference in readmission for acute coronary syndrome or acute heart failure between the 2 groups (p = 0.277, p = 0.205). For in-CICU cardiogenic shock and ejection fraction <35% at discharge, more events are observed in the conservative strategy, with a significant difference for both (p <0.001). In multivariable analysis, 1-year all-cause mortality was independently associated with revascularization between 12 and 48 hours (hazard ratio [HR] 0.372, 95% confidence interval [CI] 0.182 to 0.762, p = 0.007), ejection fraction <35% at discharge (HR 1.92, 95% CI 1.22 to 2.54, p = 0.04), and cardiogenic shock in-CICU (HR 2.69, 95% CI 1.82 to 3.78, p = 0.005).Although no evidence exists to date on the true benefit of late primary coronary intervention revascularization in patients with ST-segment elevation myocardial infarction, this practice remains common, as indicated by the results of most registries.

Bloodstream infections in cardiac intensive care units from a tertiary care center

Blood stream infections (BSIs) occur more frequently in patients hospitalized in Intensive care units (ICUs). Intravascular devices are the most frequent predisposing factor causing BSI. To compare the proportion, risk factors, microbiological profile of Blood stream Infections and Central line associated bloodstream infection in Cardiology Intensive care units (CICU) and Cardiothoracic Intensive care units (CTICU).This is a prospective study conducted by the Dept. of Microbiology along with Cardiology Intensive care unit(CICU), and Cardiothoracic Intensive care unit (CTICU) of a tertiary care centre, from June 1st 2017-Oct 312018.Laboratory confirmed BSIs (LCBSI’s), occurring more than 48hrs after ICU admission were included in the study. Identification of pathogens were done by standard methods.A total of 1640 blood cultures were analyzed (CICU=890,CTICU=750).73 Primary BSIs were observed with male preponderance.68/73 diagnosed to have non CLABSI (CTICU=35/68 51.4%, CICU=33/68, 48.5%) and 5/73 cases diagnosed to have CLABSI (CTICU=5/73, 6.84% CICU=0%) 47.94% of our isolates were Gram negative pathogens with as the predominant followed by 35.6% of Gram positive with as the major pathogen &amp; 16.4% were Candida spp. 20.5% were multi drug resistant and 10% were ESBL producers. Prevalence and incidence rates were high in CTICU (5.3% &amp; 1.5%) compared to CICU (3.7% &amp; 0%) of BSI &amp; CLABSI respectively.BSI is preventable costly complication that occur with greater frequency in the ICU settings. Strict adherence to Infection control measures such as hand hygiene, aseptic precautions during blood culture collection and bundle care measures can decrease the BSI and CLABSI incidence rates.

CLINICAL OUTCOME OF GUILLAIN BARRE SYNDROME IN THE INTENSIVE CARE UNIT OF A PEDIATRIC TERTIARY CARE HOSPITAL

Since poliomyelitis was eradicated, Guillain-Barre syndrome has been the leading cause of acute flaccid paralysis globally. Critical care and mechanical breathing may be necessary in extreme circumstances. Among paediatric patients hospitalized in the intensive care unit of a Karachi tertiary hospital, we aimed to quantify the incidence of Guillain-Barré Syndrome clinical outcomes. Cardiology Intensive Care Unit (NICH) in Karachi, Pakistan. January 9, 2020, to July 10, 2020—six months. Children admitted to the intensive care unit at NICH with GBS, as defined operationally, ranging in age from six months to twelve years, were included in the study. They stimulated the posterior tibial nerve (PTN) and common peroneal nerve (CPN), allowing for studying motor nerve conduction and using the median and ulnar nerves to measure compound muscle action potentials' onset delay, amplitude and conduction velocity (CMAPs). Research on the conduction of sensory nerves was carried out to quantify SNAPs in the sural, median, and ulnar regions. All patients were given intravenous immunoglobulin for five days at a 400 mg/kg/day dosage, as per the protocol. Clinical outcomes were evaluated using the HFG scale at discharge and four weeks. The average patient age was 5.81 ± 3.26 years out of 30. Thirteen men (43.3%) and seventeen females (56.7%) were present. Fifteen patients (53.3%) had a history of upper respiratory illness, while seven (23.3%) had a history of gastrointestinal infection. A mean HFG score of 3.03 ±1.90 was recorded. Outcomes were good for 21 patients (56.7%) and deficient for 9 (43.3%). A tertiary care hospital in Karachi reported that 56.7% of children admitted with Guillain-Barre Syndrome had good clinical results in the intensive care unit.

Resposta emocional de pacientes cardiológicos críticos durante a higiene em cuidados intensivos: um estudo prospectivo e descritivo

Objective: to analyze the emotional response of critically-ill conscious patients during daily hygiene procedures in a Cardiology Intensive Care Unit and to compare it based on the existence of previous experiences or not. Method: a prospective and descriptive study. A 30-item ad hoc survey based on the first-day hygiene procedures was applied to 148 patients. Questions are asked about the feelings during the hygiene procedures and about positive and negative aspects of the experience. The patients are compared based on whether they had been already subjected to hygiene procedures or not. Results: 67.6% were men and their mean age was 67±15 years old; 45.9% proved to be satisfied, 27% felt embarrassment and 86.3% were grateful to the professionals for talking to them during the hygiene procedures. 33.1% of the patients had never been subjected to hygiene procedures in bed, were significantly younger and single, and presented a lower cleanliness sensation. 32% stated that they would like for a family member to collaborate in the hygiene procedures. Conclusion: the patients do not feel that their intimacy is invaded when they are subjected to hygiene procedures and appreciate communication with the health personnel while this care is provided. Those who had never been subjected to hygiene procedures in bed are younger, feel more embarrassed and are more disturbed by interruptions, in addition to being more aware of them.

Factors associated with complications in ST-elevation myocardial infarction: a single-center experience

BackgroundST-elevation myocardial infarction (STEMI) is a major public health problem. This study aimed to determine the prevalence and identify the determinants of STEMI-related complications in the Cardiology Intensive Care Unit of the Sud Francilien Hospital Center (SFHC).MethodsWe retrospectively analyzed the data of 315 patients with STEMI aged ≥ 18 years. Logistic regression was used to identify factors independently associated with the occurrence of complications.ResultsOverall, 315 patients aged 61.7 ± 13.4 years, of whom 261 were men, had STEMI during the study period. The hospital frequency of STEMI was 12.7%. Arrhythmias and acute heart failure were the main complications. Age ≥ 75 years (adjusted odds ratio [aOR], 5.18; 95% confidence interval [CI], 3.92–8.75), hypertension (aOR, 3.38; 95% CI, 1.68–5.82), and cigarette smoking (aOR, 3.52; 95% CI, 1.69–7.33) were independent determinants of acute heart failure. Meanwhile, diabetes mellitus (aOR, 1.74; 95% CI, 1.09–3.37), history of atrial fibrillation (aOR, 2.79; 95% CI, 1.66–4.76), history of stroke or transient ischemic attack (aOR, 1.99; 95% CI, 1.31–2.89), and low high-density lipoprotein-cholesterol (HDL-C) levels (aOR, 3.70; 95% CI, 1.08–6.64) were independent determinants of arrhythmias.ConclusionSTEMI is a frequent condition at SFHC and is often complicated by acute heart failure and arrhythmias. Patients aged ≥ 75 years, those with hypertension or diabetes mellitus, smokers, those with a history of atrial fibrillation or stroke, and those with low HDL-C levels require careful monitoring for the early diagnosis and management of these complications.

A case of acute infective endocarditis and septic shock

Infective endocarditis (IE) marks an increasing morbidity and unchanged mortality despite advances in its diagnosis and treatment. In about 20% of IE cases are acute, with signs of sepsis and septic shock. Septic shock dramatically worsens prognosis and is an independent predictor of in &amp;ndash; hospital death. Timely diagnosis and urgent surgical intervention can improve survival in these patients. We present a case of a 47-year-old man, with no history of past or concomitant diseases, who was admitted as an emergency to the Cardiology Intensive Care Unit, during the Covid-19 pandemic, with pronounced febrile-intoxication syndrome, shortness of breath, precordial discomfort and pain, cough, haemoptysis. From laboratory studies with a pronounced infl ammatory constellation, troponin I and D-dimers are also increased. This case shows the diffi culties in the diagnosis of acute IE, the specifi cs in the clinical course of the disease, as well as the importance of urgent surgical intervention to improve survival.

Identification of Low- versus High-Risk Acute Coronary Syndrome for a Selective ECG Monitoring Strategy.

While admission of patients with acute coronary syndromes (ACS) in cardiology intensive care unit (CICU) is usual, in-hospital major outcomes in lower risk patients may be evaluated after early coronary angiography according to the European guidelines. Consecutive ACS patients were prospectively included after coronary angiography evaluation within 24 h and percutaneous coronary intervention (PCI), when required. Patients were classified as high- or low-risk according to hemodynamics, rhythmic state, ischemic and bleeding risks. Major in-hospital outcomes were assessed. From January to June 2021, 277 patients were enrolled (62.8% with ST-segment elevation myocardial infarction (STEMI) (n = 174); 37.2% with non-NSTEMI (NSTEMI) (n = 103). PCI was required for 260 patients (93.9%). Seventy-four patients (26.7%) were classified as low-risk (n = 47 NSTEMI; n= 27 STEMI) and 203 patients (73.3%) as high-risk of events. All patients were monitored in CICU. While 38 patients (18.7%) from the high-risk group reached the primary endpoint, mainly related to rhythmic or conduction disorder (n = 24, 11.8%) or unstable hemodynamics (n = 17; 8.4%), only 1 patient (1.3%) in the low-risk group had one major outcome (no fatal bleeding); p < 0.01. The negative predictive value of our patient stratification for the absence of major in-hospital outcome was 100% (CI95%: 100-100%) for STEMI and 97.9% [CI95%: 93.2-100%] for NSTEMI patients. Stratification of ACS patients after early coronary angiography and most of the time PCI, identify a population with very low risk of in-hospital events (1/4 of all ACS and 1/2 of NSTEMI) who may probably not require ECG monitoring and/or CICU admission. (NCT04378504).

Pressure-strain loops unveil haemodynamics behind mechanical circulatory support systems.

Mechanical circulatory support (MCS) systems are increasingly employed in cardiogenic shock and advanced heart failure. A thorough understanding of the complex interactions occurring among heart, vasculature, and device is essential to optimize patient's management. The aim of this study is to explore non-invasive haemodynamic profiling of patients undergoing MCS based on pressure-strain (PS) analysis. Clinical and echocardiographic data from consecutive patients undergoing different MCS systems positioning/implantation admitted to the third level cardiological intensive care unit of Siena Hospital from August 2021 to November 2021 were retrospectively reviewed. Patients without a useful echocardiographic exam or without arterial blood pressure recording at the time of echocardiography were excluded. Myocardial work analysis was performed in the included patients. We reviewed 18 patients, of which nine were excluded. Included patients were three patients with intra-aortic balloon pump (IABP), two patients with durable left ventricular assist device (dLVAD), two patients with Impella®, one patient with extracorporeal membrane oxygenation (ECMO), and one patient with ECMO and IABP. Myocardial work analysis was feasible in each included patient. The use of IABP shifted the PS curve rightward and downward. Global work index (GWI) and global wasted work (GWW) decreased after IABP positioning, whereas global work efficiency (GWE) increased. The use of continuous-flow pumps, whether temporaneous (Impella®) or long term (dLVAD), induced a change in the PS loop morphology, with a shift towards a triangular shape. ECMO positioning alone resulted in a narrowing of the PS loop, with a decrease in GWI and GWE and an increase in GWW and mean arterial pressure. The combined used of IABP with ECMO widened the PS loop and improved GWI and GWE. PS loops analysis in patients undergoing MCS seems to be feasible and may unveil MCS-induced haemodynamic variations. Myocardial work could be used to monitor ventricular-arterial-device coupling and guide tailored MCS management.

P190 TWIDDLER’S SYNDROME IN A 96–YEAR–OLD PATIENT TREATED BY REPOSITIONING THE VENTRICULAR LEAD

Abstract A 96–years–old woman was admitted to our cardiological intensive care unit in December 2022 with atrioventricular dissociation, with a junctional ventricular escape rhythm at a rate of 38 beats per minute, and an atrial rhythm dissociated from the ventricular rhythm, at a rate of 80 beats per minute (Figure 1). The patient had a history of third–degree atrioventricular block, effectively treated with single–chamber pacemaker implantation (Assurity MRI SR, Abbott), operation performed approximately 10 months before access, in February 2022. The patient underwent a chest X–ray, which showed "coiling" of the ventricular catheter in the pacemaker pocket area (left subclavicular), with macroscopic dislocation of the ventricular electrode, which had its distal tip in the right atrium (Figure 2). Therefore, the clinical case was typical of Twiddler‘s syndrome. The patient would therefore have undergone revision surgery. An attempt was made to reposition the original lead, with passive fixation (Isoflex 1948/58, Abbott), by inserting a "straight" stylet, a procedure which was done effectively. The ventricular lead was repositioned in the right ventricular apex. The detected parameters were optimal (sensing 7 mV, ventricular barrier threshold 0.5 mV/0.4 ms, impedance 797 Ohm). The result was considered acceptable. The remainder of the hospital stay was without complications. The patient was discharged on the fifth day in good general condition. Twiddler syndrome is defined as a dislocation of one or more catheters, resulting in the catheters "coiling" in the pocket of the device. It is usually related to the manipulation of the generator by the patient itself. It usually occurs within a year of implantation and is usually more common in females, the elderly, the obese, pediatric patients, or patients with psychiatric disorders. The identification of patients at risk for this pathology, the adequate education of the patient and family regarding the management of the device, the use of catheters with active fixation, as well as the fixation of the generator device to the pectoral muscle, through non–absorbable sutures. In the case described, the patient denied manipulation of the device, which however could not be excluded, given the age of the patient.
