Abstract
Kounis syndrome (KS) is defined as an acute coronary syndrome (SCA) associated with an anaphylactic reaction. A 64–year–old sports man with no previous cardiovascular disease arrived at the emergency room of our Hospital for dyspnoea and chest pain arising during physical activity e preceded by a syncopal episode. During the physical activity (cycling) the patient reported that he had felt an insect bite sensation, with no possibility of precisely identify it. Parameters an admission were: BP 85/45 mmHg, HR 70 bpm, on ECG signs of early repolarization (Fig. 1), blood tests rise in hsTNI (328 ng/L), normal D–dimer. The transthoracic echocardiogram showed no motion abnormalities. In the suspicion of KS, therapy was set up only with ASA and statin, avoiding any drug commonly used to treat allergic reactions that could have worsen the hemodynamic and vasomotor situation by further reducing the coronary perfusion. During hospitalization, in consideration of the clinical picture and cardiovascular risk factors (dyslipidemia and previous smoking), was performed coronary angiography, which showed no obstructive lesions, but during the first injection of contrast showed vasospasm of the ostium of the right coronary artery, dominant (Fig. 2 – left), resolved spontaneously (Fig. 2 – right). The post–procedural hsTNI peak (3953 ng/L) and the presence of the European paper wasp i77 antigen to the serological dosage of the allergens supported the pathophysiology of acute coronary syndrome concomitant with allergic reaction and supported the diagnostic hypothesis of KS type I (without underlying coronary artery disease). The patient was discharged with calcium channel blocker therapy, to reduce coronary vasospasm which characterizes KS, and short–term follow–up was planned with blood tests, exercise stress test and cardiological visit which were normal. KS, though rare, is a clinical entity that should not be underestimated, especially in allergic patients with evidence of SCA without coronary occlusions. The data available in the literature are scarce and it is not clear the medium and long term prognosis. It therefore seems reasonable to follow up the patients as outpatient cardiology visits especially in the first months after the event and schedule instrumental tests control.

Abstract

Background
Patients with a CRT–D devices represent an emerging population of subjects with chronic heart failure (CHF) who, according the current guidelines, must be referred to a cardiovascular rehabilitation (CR) program. Aims. The aims of the study were to evaluate in CRT–D recipients the feasibility, safety and efficacy of a physical exercise program, in a outpatient CR setting, to evaluate the need for an individual optimization of device programming.

Methods
Twenty–six CRT–D recipients underwent clinical and functional investigations, comprehensive of symptom–limited cardiopulmonary exercise testing, during which device programming were evaluated in order to obtain an adequate increase in heart rate and to maintain resynchronization therapy during exercise. They underwent a program of physician–supervised sessions of exercise training consisting of three 90 min visit/week.

Results
Baseline patients characteristics: male sex 77%; age 69±10 years; non–ischaemic cardiomyopathy 65%; ejection fraction 38±7 %; atrial fibrillation 12%. No adverse events occurred during training. The peak oxygen uptake has been significantly increased (from 12,6±6 to 17±9ml/kg/min). During cardiopulmonary exercise testing “Brady” functions has been reprogrammed in 10 patients (38%); no modifications to the "tachy" functions of the device were necessary.

Conclusions
Cardiac rehabilitation in CRT–D recipients is safe and effective. Device brady programming during exercise may be warranted in selected patients.
P246 HOW TO OPTIMIZE THE EFFICACY OF CCM THERAPY: MULTIPARAMETRIC EVALUATION AND CASE REPORT

Abstract
We implanted a Cardiac Contractility Modulation (CCM) device in a 66–year–old man with congestive acute heart failure (AHF) refractory to optimized medical therapy and non–responder to CRT–D since 2015. The patient was evaluated multiple times and declared ineligible for a new heart by several heart transplant centers. Effective periodic Levosimendan treatments were performed before the implantation.. However hospitalizations still occurred monthly. The Echo exam, on the day of the implant, showed a left ventricular ejection (LVEF) fraction of 25%, PAPS of 30 mmHg, and E/E’ of 26. Interrogation of the CRT–D revealed an AF burden of 35% and several episodes of tachyarrhythmia at high frequency (130 bpm). The benefits of CCM therapy were almost immediate with the disappearance of breathlessness and the absence of hospitalizations for seven months. Only in June 2022, the patient was admitted to the ER for HF symptoms. At the admission, the heart rate was 125 bpm and, by performing the follow–up of the CCM device, the percentage of delivered therapy was low (&lt;20%) due to the high heart rate. The interrogation of the ICD showed a reduced AF Burden (19 %). However, in the two weeks before the admission, several episodes of organized supraventricular tachycardia (SVT) conducted 1:1, at a rate of around 140 bpm, were recorded and stopped the CCM the device from delivering any impulse, in the absolute refractory period. In the HF Diagnostics implemented in the ICD, we also noticed an indication of fluid overload consistent with a steep reduction of intrathoracic impedance in the exact same time frame. Consequently, we increased the dosage of BB to reduce the heart rate and allow CCM delivery to reach a percentage higher than 80% within the 24 hours timespan. The clinical status of the patient improved immediately in the next following days. The HF diagnostics of ICD, after three weeks from discharge, revealed an increase in intrathoracic impedance and a decrease in hypervolemia which were consistent with the improved symptoms reported by the patient. Finally, the echocardiographic exam at 6 months from the implant showed an EF of 32, PAPS of 30 mmHg, and E/E’ of 12 which justified a decrease in the score of the Minnesota Living with Heart Failure Questionnaire (MLWHF) from 80 (before CCM) to 36 after the implantation. A multiparametric evaluation of CCM delivery must be performed during the patient‘s follow–up to maximize the efficacy of the therapy itself.

Abstract

Background
Several studies have evaluated the role of QRS duration (QRSd) or QRS narrowing as predictor of response to cardiac resynchronization therapy (CRT) in order to reduce non–responders. However, their results have been conflicting. In our study we analyzed retrospectively a cohort of patients from three centers to better correlate the association between the relative change in QRS narrowing index (QI) and clinical outcome and prognosis in patients who underwent CRT implantation.

Methods
We included 398 patients in whom a CRT device was implanted in accordance with current guidelines in our three centres. Baseline clinical variables, echocardiographic parameters and pharmacological therapies were included. QRS duration before and after CRT implantation and QI [(pre implant QRS duration – QRS duration during CRT)/pre implant QRS duration × 100] were measured.

Results
Respect to echocardiographic follow up at 6 months, a significant improvement in all parameters (EF, LVEDV, LVESV) was observed. In 68% of patients, LVESV decreased by 10% or more. QI was significantly related to reverse remodelling (r = + 0.22; 95% CI: 0.11 to 0.32, p = 0.001). The cut–off value of QI that predicted best LV reverse remodelling after 6 months of CRT was 12.25% (sensitivity 65,49%, specificity 75%, area under the curve 0.7, p = 0.001). Regarding clinical outcomes at 12 mounths, a statistically significant difference was found between patients with a QI &lt; 12.25%, and those with a QI &gt; 12.25%, in terms of NYHA class worsening (p 0,04). Another statistically significant difference was found analyzing the relation between QI and the causes of deaths, the mean of the QI of patients who died from cardiovascular causes was lower than patients who died of other causes. (p 0,0179).

Conclusions
Therefore decrease in QRSd after CRT initiation was related to greater echocardiographic reverse remodelling and better outcome from death or cardiovascular hospitalization. Even if larger studies are needed, QI seems to be an easy–to– measure variable that could be used or evaluated to predict CRT response.

Abstract
Out–of–hospital cardiac arrest (OHCA) is a major public health problem, and ventricular fibrillation (VF) is the most frequently encountered initial rhythm when cardiac disease is the cause of the arrest. It can be treated with successful defibrillation, if prompt intervention, otherwise it rapidly progresses to non–shockable rhythms, with survival rates ranging from 3 to 10%. The early defibrillation strategy led to a significant improvement in outcome; although Automated External Defibrillators (AEDs) are still used in &lt;3% of OHCAs. All consecutive OHCAs registered in Piacenza from January 2013 to June 2022 in which CPR was initiated were analysed. "Progetto Vita", the first European early defibrillation project, was born in Piacenza in 1999, with the aim of improving the diffusion of AEDs in public places, sports centres, workplaces and homes, in order to allow timely treatment of the OHCA by non–medical personnel (citizens, police…) awaiting the arrival of advanced emergency services (EMS). During the review period, 3,124 patients were treated for OHCA; 323 had VF; VF occurred predominantly at home (73%), in men (75%); the mean age was 70 years. CPR by lay citizens was performed in 35 cases (11%) with a survival rate of 63%. AED used by lay or police was used in 30 cases (9%) with a survival rate of 77%. Cardiac comorbidities were observed in 67 patients (21%), predominantly male, with CAD being the most common disease. The main characteristics are listed in Table 1. There were 237 deaths (73% fatality rate), 41 (17%) recorded after EMS arrival. Among hospitalized patients, VF was related to coronary artery disease (70%) and STEMI was the most frequent manifestation. Overall, 87 (27%) patients survived and were hospitalized. Multivariate logistic regression analysis showed that layman CPR (OR 2.52, 95% CI 1.04, 6.1, p=0.04) and AED use (OR 7.15; 95% CI 2.66, 19.19, p&lt;0.001) were both independent predictors of survival. VF in the general population is still poorly predictable and mortality remains high: the implementation of the diffusion of public AEDs seems effective in improving survival.
P262 PREDICTORS OF ICD IMPLANTATION: THE ROLE OF THE WEARABLE CARDIOVERTER DEFIBRILLATOR
Authors: Bolognesi M , Rossi L , Biagi A , Bricoli S , Sticozzi C , Comastri G , Aschieri D 
Published: May 2023

Abstract

Background
Previous studies established a role for the wearable cardioverter defibrillator (WCD) In patients with transient risk of sudden cardiac death ( SCD) . In clinical trials, nearly 40% of patients received implantable cardioverter–defibrillator (ICD) implantation at the end of WCD use. It’ unknown if WCD can be usefull in final ICD implantation indication.

Objectives
We aimed to describe the clinical predictors of ICD implantation rate at the end of WCD use in a real–world single center experience.

Methods and results
Between August 2017 and June 2022, 60 consecutive patients receiving a WCD at Piacenza Hospitals were retrospectively included in this analysis: : mean age 66.9±11.9 years, 56.6% with ischaemic cardiomyopathy, 38.3% with dilated cardiomyopathy, 5% after implantable cardioverter–defibrillator explant. A total of 34 participants (56.6%) received implantable cardioverter–defibrillator (ICD) implantation at the end of WCD use. We evaluated clinical features related to ICD implantation rate with Chi Square test and Student’s t test. Female sex was related with no ICD implantation ( ICD 5,9% vs no ICD 23,1%, p= 0,03), whilst Low ejection fraction at beginning of evaluation was related with ICD implantation ( ICD 27.1±9.3 vs no ICD 33.1±11.9, p=0,03). Although in our population there weren’t shock of WCD, the strongest clinical predictor was arrhythmic event recordered at WCD monitoring both non sustained ventricular tachicardia, sustained ventricular tachicardia and supraventricular tachicardia ( ICD 20 vs no ICD 0, p &lt; 0,01). Age ( ICD 66.6±11.9 vs NO ICD 67.4±11.9, p=0,7) and etiology of cardiopathy both ischemic and non ischemic ( ICD 52% vs no ICD 53,8%, P=0.5) were not factors associated with ICD implantation.

Conclusion
In our study the rate of ICD implantation after wearing time of WCD is consistent but slightly major to European registries. Arrhythmic Event recordered at WCD monitoring is related with ICD implantation, so WCD, when it is used, may be a further help in final ICD implantation.

Abstract

Background
Previous studies established a role for the wearable cardioverter defibrillator (WCD) in patients with transient risk os sudden cardiac death ( SCD) . The WEARIT–II Registry highlighted an higher burden of ventricular and atrial arrhythmic events in women than in men, in spite of a similar ICD implantation rates.

Objectives
We aimed to describe the sex differences in WCD use and compliance. Moreover we reviewed the rate of cardiac events detected with WCD and the rate of ICD implantation in women in a real–world single center experience.

Methods and results
Between August 2017 and June 2022, 60 consecutive patients receiving a WCD at Piacenza Hospitals were retrospectively included in this analysis: mean age 66.9±11.9 years, 56.6% with ischaemic cardiomyopathy, 38.3% with dilated cardiomyopathy, 5% after implantable cardioverter–defibrillator explant. 8 patients were women (13.3%). Women and men presented similar clinical characteristics. Median WCD usage period and median daily wear time were not different between women and men (49.6±25.3 vs 51.8±32.8 days, 23.6±0.3 vs 23.1±1.7 hours, respectively). No ventricular fibrillation was detected in the monitoring period. Non–sustained ventricular tachycardia and atrial arrhythmias were similar between women and men. However, ICD implantation rate at the end of WCD use was significantly lower in women than and men (25% vs 61.5%; p&lt; 0.01).

Conclusions
In this real word analysis WCD was underused in women despite a nice compliance. A similar burden of ventricular and atrial arrhythmic events were detected, with a lower ICD implantation rate at the end of WCD use in women than in men.
P277 MULTIFACTORIAL RECURRENT CHYLOUS ASCITES: THE CASE REPORT OF A PATIENT WITH HEART FAILURE WITH PRESERVED EJECTION FRACTION (HFPEF), LIVER DISEASE AND PAST ABDOMINAL SURGERY
Authors: Pandolfi A , Vicenzi M , Carugo S 
Published: May 2023

Abstract
Chylous ascites is the accumulation of triglyceride–rich fluid in abdominal cavity. It is caused by lymphatic ducts injury, usually as consequence of surgery, neoplasia, or infection. Rarely, it can also occur from heart failure, pericarditis, or cirrhosis. We report the case of a 66–year–old man electively hospitalized for acute renal failure and anasarca state. The cardiological history was significant due to acute myocardial infarction treated with CABG, PM implantation for complete AV block, atrial fibrillation, and type 2 diabetes mellitus. The entero–hepatological history started in 2019 when, two months after abdominal surgery for an incarcerated hernia, he developed chylous ascites and chylotorax. Starting from 2021, the patient presented recurrent episodes of tense ascites, requiring periodic paracentesis. Haematological and infectious disease evaluation resulted negative, liver biopsy showed congestive hepatopathy with fibrosis, while venous catheterization found high right filling pressure with not portal hypertension. Patient was treated with Apixaban 2.5 mg b.i.d., Furosemide 50 mg b.i.d., Metformin 1500 mg, Enalapril 20 mg, and Simvastatin 20 mg. During the hospitalization other paracentesis confirmed the chylous nature of the effusion, echocardiography (despite very bad acoustic windows) showed preserved left ventricle systolic function (LVEF 55%), 3rd degree LV diastolic disfunction, and dilatation of right ventricle, atria, and inferior Vena Cava. Right heart catheterization confirmed the presence of LV restrictive physiology, combined pulmonary hypertension, and ruled out the diagnosis of constrictive pericarditis. In hospital treatment focused on resolving acute renal failure and hypervolemia through intravenous diuretic and Albumin and on optimizing cardiological therapy. The patient was discharged with the following treatment: Apixaban 2.5 mg b.i.d., Furosemide 50 mg b.i.d., Canrenone 100 mg b.i.d., Empagliflozin 10 mg, Simvastatin 20 mg, and indication to hypo–lipidic diet. This case highlights how the coexistence of different predisposing factors of chylous ascites (past abdominal surgery, heart failure and liver disease) can amplify each other. Recognizing the single role of each of them is of pivotal importance to elaborate targeted treatment. Moreover, in literature, there are some cases of chylous ascites associated with constrictive pericarditis and with severe heart failure, but to our knowledge not with coexistence of HFpEF.
P282 PAUCISYMPTOMATIC POST–COVID MYOCARDITIS IN A YOUNG ATHLETE DURING THE DIAGNOSTIC INVESTIGATIONS BEFORE RETURNING TO COMPETITIVE PRACTICE, POSSIBLE USEFULNESS OF THE GLS ANALYSIS

Abstract
It is now known that the Covid19 infection can cause myocardial inflammatory damage. Several studies have shown that the echocardiographic parameter of the global longitudinal strain (GLS) was reduced compared to the general population even in paucisymptomatic patients. A young competitive athlete came to our observation for the diagnostic investigations before returning to competitive practice (return to play protocol) after Sars–Cov2 infection. The electrocardiogram did not show significant abnormalities as well as spirometry examination. Negative inflammation indexes and markers of myocardial damage were observed. The cycloergometer test showed no signs of myocardial distress, rapid chronotropic increase and dyspnea at 100W work load. HolterECG was performed showing 830 isolated ventricular ectopic beats. Echocardiographic examination showed preserved left ventricular systolic function (FEVS 59% – Simpson method) with a moderate reduction of GLS parameter –16,9%. The cardiopulmonary exercise test (CPET) showed an early anaerobic threshold and a normal pVO2max but not in line with the presumed range for a top–level athlete. Putting together the symptoms described, the CPET data and GLS parameter, despite the negative first–level investigations he underwent MRI that documented a myocardial edema in the mid–basal region of inferior and inferolateral walls of the left ventricle. Suitability for competitive practice was blocked, a gradual physical readaptation path was started and therapy with low–dose bisoprolol was set. An important clinical improvement is reported at the 6–month follow–up with evidence of normalization of the GLS parameter –23%. The CPET howed a realignment of the HR/VCO2 curve with a late threshold and increment of pVO2max. The 6–month control MRI examination showed almost no signs of myocardial inflammation and so the patient was made suitable for returning to competitive sport. In our case first–level investigations did not support any hypothesis of myocardial inflammation. The presence of stress symptoms confirmed by CPET data but especially the reduction of GLS parameter led to a deepening investigation with MRI that confirmed the presence of myocardial inflammatory lesion. Our case suggests that within a “return to play” protocol for athletes with recent SarsCov2 infection, the analysis of left ventricular systolic function by GLS may represent an additional useful element to be considered in support of standard investigations.
P285 DESIGN OF A NETWORK FOR THE IN–SERVICE MANAGEMENT OF ACUTE CORONARY SYNDROMES IN THE PROVINCE OF TERAMO

Abstract
Acute Coronary Syndrome (ACS) are events due to the rupture/erosion of a coronary atherosclerotic plaque, with activation of the coagulation cascade and critical reduction of the flow, which is expressed in a spectrum of clinical scenario ranging from infarction with ST elevation (STEMI)1, to non ST elevation ACS (NSTE–ACS)2. Timely reperfusion therapy, either pharmacological or via percutaneous coronary intervention (PCI)1, is indicated for patients with STEMI. Patients with NSTE–ACS should undergo initial risk stratification, followed by invasive evaluation, depending on the patient‘s risk profile2. (Figure 1). It is necessary to create an effective network among hospitals, to make available the fastest and most effective therapy for the greatest number of patients with ACS. The European Society of Cardiology (ESC) guidelines suggest the implementation of such regional networks1. Achieving this goal is possible only by sharing a common protocol. The province of Teramo was equipped with a cardiological network in 2011. There are 2 simple structures, a structure with a spoke CCU (Giulianova) and the Hub structure with CCU and Cath–lab (Teramo). The simple structures refer to the Hub center when direct access to cath–lab is required and to spoke CCU for those patients who do not require immediate coronary angiography. Spoke CCU unit refers to Hub center for the access of patients with ACS to the cath–lab3. On the basis of epidemiological data4 it can be expected that in the province of Teramo there are about 230–250 STEMI and 450–500 NSTE–ACS/year. Teramo‘s cath–lab performed 248 primary PCIs on STEMI, and 390 PCIs on NSTE–ACS. In the spoke CCU in 2021, there were 1005 patients hospitalized with ACS. Almost all of them were transferred/transported for coronary angiography according to risk stratification. There were 326 patients discharged with a diagnosis of ACS undergoing PCI. That data made it necessary to transport the patient in hemodynamics for angiography study and interventional procedure, and possible retransfer to the spoke center. This strategy is called service. The advantages and safety of this procedure have already been described7. The implementation of service strategy would make a clear increase in interventional procedures foreseeable (ideally the approximately 100 patients with ACS accessing the Spoke CCU should undergo PCI with adequate timing in 70% of cases) and an optimization of work for the centers and of patient care.
