Aims The number of patients with heart failure (HF) and implantable cardiac electronic devices has been growing steadily. Remote monitoring care (RC) of cardiac implantable electronic devices can facilitate patient-healthcare clinical interactions and prompt preventive activities to improve HF outcomes. However, studies that have investigated the efficacy of remote monitoring have shown mixed findings, with better results for the system including daily verification of transmission. The purpose of the RESULT study was to analyse the impact of remote monitoring on clinical outcomes in HF patients with implantable cardioverter-defibrillator [ICD/cardiac resynchronization therapy-defibrillator (CRT-D)] in real-life conditions. Methods and results The RESULT is a prospective, single-centre, randomized trial. Patients with HF and de novo ICD or CRT-D implantation were randomized to undergo RC vs. in-office follow-ups (SC, standard care). The primary endpoint was a composite of all-cause death and hospitalization due to cardiovascular reasons within 12 months after randomization. We randomly assigned 600 eligible patients (299 in RC vs. 301 in SC). Baseline clinical and echocardiographic characteristics were well-balanced and similar in both arms. The incidence of the primary endpoint differed significantly between RC and SC and involved 39.5% and 48.5% of patients, respectively, (P = 0.048) within the 12-month follow-up. The rate of all-cause mortality was similar between the studied groups (6% vs. 6%, P = 0.9), whereas hospitalization rate due to cardiovascular reasons was higher in SC (37.1% vs. 45.5%, P = 0.045). Conclusion Remote monitoring of HF patients with implanted ICD or CRT-D significantly reduced the primary endpoint rate, mostly as a result of a lower hospitalization rate in the RC arm (ClinicalTrials.gov Identifier: NCT02409225).

Introduction The aim of this study is to estimate how much of the recent decrease in mortality among patients with myocardial infarction with ST-segment elevation (STEMI) can be attributed to improved treatment strategies, and how much it is related to changes in baseline clinical characteristics, and to compare these findings for men and women. Material and methods This was a retrospective analysis of 32,790 patients with STEMI from the Polish Registry of Acute Coronary Syndromes PL-ACS hospitalised in 2005 and 2011. Changes in treatment strategies including pharmacotherapy were analysed. Observed in-hospital and 12-month mortality rates were compared with the outcomes in the groups matched on the propensity scores. Results There was a substantial improvement in STEMI patient management between 2005 and 2011 in Poland. It included greater use of percutaneous coronary interventions and other guideline-based adjunctive therapies, and it was associated with a significant decline in in-hospital mortality. Relative 12-month mortality reduction rates were less pronounced and more related to changes in patients' clinical characteristics. Higher mortality risk reductions were observed in women and were driven by relatively more positive changes in their baseline risk profiles when compared to men. Conclusions The progress in the treatment strategies has helped to achieve better survival rates in STEMI patients. However, the ongoing changes in clinical characteristics of patients also played an important role, especially in women. Clinicians should focus on modifiable risk factors and post-discharge management to possibly prolong the positive aspects of in-hospital efforts.

Objectives The aim of the DAPT-DRAGON registry was to asses long-term outcomes and the length of dual antiplatelet therapy (DAPT) in patients treated with percutaneous coronary intervention (PCI) due to drug-eluting stent in stent restenosis (DES-ISR) with drug-eluting balloons (DEB) or thin-DES. Background Data regarding the duration of DAPT in patients with DES-ISR treated with PCI is still undergoing research and observation, and the adequate duration of DAPT in this group of patients is not unambiguously sanctioned. Methods Overall, 1,367 consecutive patients with DES-ISR who underwent PCI with DEB or DES, were entered into the multi-center DAPT-DRAGON Registry (Fig. 1). The mean age was 66.7±9 years (70.5% males). The median follow-up was 3.3 years. There were 34.1% patients with chronic coronary syndrome, 35.2% with unstable angina, 2.9% with ST segment elevation myocardial infarction and 27.7% with non-ST segment elevation myocardial infarction (MI). We assessed selected study endpoints according to the duration of DAPT (≤3 vs. >3 months and ≤6 vs. >6 months), before and after propensity score matching (PSM): stroke, target lesion revascularization (TLR), target vessel revascularization (TVR), MI, death and device-oriented composite endpoints (DOCE). Results Among predictors of increased DOCE rate before PSM, we demonstrated: PCI with DEB vs. DES (p6 months) before PSM revealed superiority of thin-DES+DAPT >6 months vs. DEB+DAPT >6 months for DOCE (p3 months) had no significant influence on assessed long-term outcomes, while the percentage of stroke free survival was significantly lower in the group of patients with DAPT ≤6 months vs. >6 months (p=0.01; Fig. 2). Conclusions Long-term treatment with DAPT (>6 months) in patients with DES-ISR with DES implantation is related to better long-term outcomes in terms of lower rate of DOCE, TVR and TLR compared to PCI with DEB. DAPT >6 months is related to a greater rate of strokes, independently of the type of treatment (thin-DES and DEB) compared to DAPT ≤6 months. Funding Acknowledgement Type of funding sources: None.

Introduction COVID-19 pandemic has caused not only an increase in overall and cardiovascular mortality, but also hindered access to health care, diagnosis and treatment of diseases other than coronavirus infection. Aim Assessment of the impact of the SARS-CoV-2 pandemic on the rate of diagnosis and therapy of pulmonary hypertension (PH) in Poland, along with an analysis of the incidence and course of COVID-19 among patients (pts) diagnosed with PH, treated under the National Health Fund program, registered in the national BNP-PL database. Methods The records of the complete population of Polish pts treated under the National Drug Program of PH (PAH and CTEPH), registered in the national database of BNP-PL, updated on an ongoing basis by all PH centers, were analyzed. The frequency of SARS-CoV-2 infections, the clinical severity of their course and the mortality were reviewed, taking into account the specific therapies used. The basic clinical characteristics of the group of sick and deceased patients were compared to the remaining patients registered in the BNP-PL database. The rate of increase of new diagnoses ended with inclusion in the Drug Program between March and December 2020, compared to the corresponding periods of the previous year, and the change in the treatment profile were compared. Results The analysis included 1704 pts (PAH 1134, CTEPH 570). The incidence of SARS-CoV-2 infections was 3.8% (n=65), including PAH 2.7% (n=46) and CTEPH 3,2% (n=18). 32 patients (49%) required hospitalization. Mortality rate was 28% (18/65) – including 7/18 outside of hospital. Those who died due to COVID-19 were older (mean age 68.4±15.8 vs. 50.8±18.8 yrs; p Conclusions COVID-19 pandemic deeply influenced the diagnostic and therapeutic process of pulmonary hypertension by reducing the number of new diagnoses, escalation therapy and increased overall mortality in this population. This may be due in part to the conversion of some PAH centers into hospitals treating patients infected with SARS-CoV-2, as well as to patients' fear of admitting to hospital despite clinical deterioration. Pulmonary hypertension is linked to markedly increased mortality in COVID-19, similarly for PAH and CTEPH. Intriguing finding of lower infection rate may be linked to protective lifestyle or specific therapies. Funding Acknowledgement Type of funding sources: None.

Despite well-defined therapeutic low-density lipoprotein cholesterol (LDL-C) target in the highest-risk population, low percentage of patients is administered with intensive lipid-lowering therapy and achieves recommended levels. Therefore, based on the Hyperlipidaemia Therapy in tERtiary Cardiological cEnTer (TERCET) Registry data we investigated the characteristics of lipid profile and management of dyslipidemia in acute coronary syndrome (ACS) patients. 19,287 consecutive patients hospitalized between 2006 and 2016 have been included in the study. The lipid profile on admission and long-term laboratory effects (namely the efficacy of achievement of the therapeutic target of LDL-C70 mg/dl [1.8 mmol/L]) after follow-up of twelve months were assessed. Acute coronary syndromes occurred in 36.1% of the Registry patients including 14.3% with ST-elevated myocardial infarction (STEMI), 10.2% with NSTEMI and 9,9% with unstable angina (UA). The highest LDL-C concentration on admission was observed in the STEMI subgroup (mean level: 127.0 mg/dL [3.28 mmol/L]). In 76.6% of the Registry patients LDL-C concentration was lower than 130 mg/dL and in 20.7% was lower than 70 mg/dL at baseline. The patients with baseline LDL 70 mg/dL were usually presented with the worst clinical profile. In 91,6% of the patients admitted due to acute coronary syndrome, statin treatment was administered at discharge. Among them, 37.6% received intensive statin therapy. In the 12-month follow-up, in 32.4% of patients admitted due to STEMI, LDL-C concentration was lower than 70 mg/dL, compared to 29.9% in patients with NSTEMI and 27.8% in patients with UA. In conclusion, STEMI patients are less clinically burdened with concomitant risk factors and comorbidities, but present significantly worse baseline lipid profile values. Among the patients already treated with statins, patients with ACS regardless of its type have significantly higher LDL-C than patients with SA. Despite discrepancies in the clinical profile on admission, achievement of the therapeutic target equalizes the outcomes in 12-month follow-up, however with the best results for STEMI patients.

Background Remote monitoring (RM) of cardiac implantable electronic devices (CIED) in patients with heart failure allows to regularly analyze the devices" and patients" conditions. Purpose The purpose of this study was evaluation of the ultimate transmissions sent before death in patients monitored remotely. Methods The last transmissions delivered by the devices in patients enrolled into COMMIT-HF Registry (NCT02536443) who died when monitored remotely have been retrospectively analysed. The characteristics and contents of the transmissions and clinical reactions undertaken have been obtained from the RM systems of four major RM providers. Results Of 1,306 patients with CIEDs who were enrolled at the RM programme in our centre, 267 died and their last transmission occurred less than 90 days before death, of which 133 (49.8%) were scheduled and 134 (50.2%) alert-triggered. The median period between transmission and death was 31 days for scheduled and 8 days for alert-triggered transmissions. The most frequent alert-triggered transmissions were atrial fibrillation/flutter (35.8%) and ventricular tachyarrhythmias (24.6%). A clinical reaction has been undertaken after 9.8% of planned and 67.1% of alert-triggered transmissions and consisted mainly of telephone consultations and referrals for hospital admissions. Conclusions This is the first analysis of the ultimate transmissions delivered by CIEDs before death. In approximately 50% of patients, the last transmission has been alert-triggered. Hence, an appropriate organization of the RM facility, which should immediately analyse and react to the transmission, seems mandatory to obtain clinical benefit in patients with HF and RM.

Main funding source(s): National Institute of Cardiology in Warsaw Statutory Grant Background The presence of atrial fibrillation (AF) in cardiac resynchronization therapy (CRT) recipients is common and AF is a marker of poorer CRT response. The negative influence of AF on CRT efficacy is mediated mainly by the drop of the effectively captured biventricular paced beats percentage (BiVp%) which should exceed 95-98% to warrant good CRT response. Sinus rhythm (SR) restoration may improve CRT efficacy which in turn may protect AF recurrence. However, there is lack of randomized studies comparing rhythm and rate control strategies in these patients. Purpose The purpose of the Pilot-CRAfT study (NCT01850277) was to compare the efficacy of rhythm vs rate control strategy in CRT patients with long-standing persistent or permanent atrial fibrillation. Methods The study included patients with CRT and permanent or persistent AF lasting for ≥6 months, resulting in BiVp% Results The study included 43 CRT patients (97,7% males) aged 68,4 (SD: ±8,3) years with mean BiVp% 82,4% ±9,7% at baseline. The mean duration of AF paroxysm was 25 ±19 months. The mean baseline left ventricular ejection fraction (LVEF), left atrium area and maximal oxygen uptake (VO2max) were: 30 ±8%, 33 ±7 cm2, 14 ±5 mL/(kg*min), respectively. The EEC was performed in 19 out of 22 patients assigned to the rhythm control arm. The immediate success rate of EEC was 58%. 42% of the rhythm control arm patients remained in SR after 12 months. In the rate control group 1 person underwent AVNA and in 1 patient spontaneous SR resumption was observed. After 12 months there was significant BiVp% increase in both the rhythm and the rate control arms (98,1 ±2,3 vs 96,3 ±3,9%, respectively. The BiVp% differences between the groups were not significant (P = 0,093). However, in the per protocol analysis, the rhythm control group had greater LVEF after 12 months as opposed to the rate control arm (36,8% vs 29,9% respectively, P = 0,039). The LVEF raised significantly in the rhythm control group (ΔLVEF 5,0 (95%CI: 1,54; 8,46)). No significant differences between the groups in the VO2max, QoL, clinical and safety end-points were noticed. Conclusions Structured follow-up of CRT patients with long-standing persistent or permanent AF leads to significant BiVp% increase exceeding 95%. The rate control strategy did not improve CRT effectivness, irrespective of high BiVp%. However limited in the efficacy, the rhythm control strategy may improve CRT outcome in these patients, resulting in LVEF increase.

Background, As a consequence of the worldwide increase in life expectancy and due to significant progress in the pharmacological and interventional treatment of heart failure (HF), the proportion of patients that reach an advanced phase of disease is steadily growing. Hence, more and more numerous group of patients is qualified to the heart transplantation (HT), whereas the number of potential heart donors has remained invariable since years. It contributes to deepening in disproportion between the demand for organs which can possibly be transplanted and number of patients awaiting on the HT list. Therefore, accurate identification of patients who are most likely to benefit from HT is imperative due to an organ shortage and perioperative complications. Purpose The aim of this study was to identify the factors associated with reduced survival during a 1.5-year follow-up in patients with end-stage HF awating HT. Method We propectively analysed 85 adult patients with end-stage HF, who were accepted for HT at our institution between 2015 and 2016. During right heart catheterization, 10 ml of coronary sinus blood was additionally collected to determine the panel of oxidative stress markers. Oxidative-antioxidant balance markers included glutathione reductase (GR), glutathione peroxidase (GPx), glutathione transferase (GST), superoxide dismutase (SOD) and its mitochondrial isoenzyme (MnSOD) and cytoplasmic (Cu/ZnSOD), catalase (CAT), malondialdehyde (MDA), hydroperoxides lipid (LPH), lipofuscin (LPS), sulfhydryl groups (SH-), ceruloplasmin (CR). The study protocol was approved by the ethics committee of the Medical University of Silesia in Katowice. The endpoint of the study was mortality from any cause during a 1.5 years follow-up. Results The median age of the patients was 53.0 (43.0–56.0) years and 90.6% of them were male. All included patients were treated optimally in accordance with the guidelines of the European Society of Cardiology. Mortality rate during the follow-up period was 40%. Multivariate logistic regression analysis showed that ceruloplasmin (odds ratio [OR] = 0.745 [0.565–0.981], p=0.0363), catalase (OR = 0.950 [0.915–0.98], p=0.0076), as well as high creatinine levels (OR = 1.071 [1.002–1.144], p=0.0422) were risk factors for death during 1.5 year follow-up. Conclusions Coronary sinus lower ceruloplasmin and catalase levels, as well as higher creatinine level are independently associated with death during 1.5 year follow-up.

Introduction Despite significant advances in the prevention and treatment of heart failure (HF), the prognosis for patients with advanced stage of the disease is still poor. Therefore, a better understanding of the underlying HF pathophysiological mechanisms is crucial to improve prognosis in patients with advanced HF. One important research area is the role of inflammation in the pathophysiology of HF. Purpose This study aimed to investigate factors associated with mortality in HF patients with particular emphasis placed on inflammatory markers. Methods This is a prospective analysis of 282 optimally treated HF patients hospitalised in Cardiology Department between 2016 and 2018 for heart transplantation (HT) evaluation. Patients with contraindications to HT were excluded from the study. At the baseline echocardiography, routine laboratory tests, an ergospirometric exercise test, and right heart catheterisation were performed in all patients. In addition, 10 ml of peripheral blood was collected to determine inflammatory biomarkers. Human procalcitonin and copeptin concentrations were measured by the sandwich enzyme-linked immunosorbent assay (ELISA) with the commercially available kit. A highly sensitive latex-based immunoassay was used to detect plasma C-reactive protein (CRP) using the COBAS Integra 70 analyzer. The end-point of the study was all-cause mortality during one-year follow-up. The study protocol was approved by the Local Ethics Committee of our medical university. All patients provided informed, voluntary consent to participate in the study. Results The median age of patients was 57 (51–60) and 87.6% of them were male. A total of 79 (28%) patients died during a one-year follow-up. Multivariate analysis of the Cox proportional hazard model confirmed that procalcitonin [hazard ratio (HR) 1.003 (1.002–1.003), p Conclusions Our study demonstrated that higher procalcitonin, CRP and copeptin serum concentrations as well as higher ESR and lower albumin serum concentrations are independently associated with reduced survival in patients with advanced HF.

Introduction Permanent right ventricle pacing leads to left ventricle dyssynchrony, systolic dysfunction, remodeling, and symptomatic heart failure in the long run. Valsartan is well known for its preventive anti-remodeling function in the post infarction heart remodeling. Objectives To assess the effect of valsartan on left ventricle contractility, measured as global longitudinal stain, and its remodeling in patients with second and third degree atrioventricular block with first-time implantation of dual chamber pacemaker. Methods This was a randomized, double-blind, placebo controlled single center study. One hundred eligible patients were assigned in a 1:1:1 fashion to receive placebo, valsartan 80mg or 160mg once daily, respectively. Echocardiographic assessment of left ventricle geometry, its systolic and diastolic function was performed at baseline and at twelve months. Global longitudinal strain (GLS) was measured off-line with EchoPac software. One patient from placebo group suffered stroke. We present the baseline date for 100 enrolled patients and follow-up data for 88 patients who have completed the study. Data in valsartan arms are pooled in one group. Results Results are presented in table. Data are presented as mean and standard deviation. Valsartan alleviates diastolic dysfunction, left ventricle dilation and protects from loss of systolic function. Conclusion Valsartan has protective effect of left ventricle contractile function and remodeling. It may be useful in prevention of pacing induced heart failure.

Background Risk stratification is a critical component of selection process of the patients with end-stage heart failure (HF) who are considered for heart transplantation (HT). Due to the constantly increasing number of the patients placed on the transplant waiting lists and a global shortage of organs available for HT, the key issue becomes an accurate risk stratification of death and proper organ allocation to these patients who will benefit the most from this form of treatment. Purpose The aim of this study was to identify the factors associated with mortality during a 1.5-year follow-up in patients with end-stage HF awaiting HT. Methods We prospectively analysed 72 patients with advanced HF awaiting HT at our institution between 2015 and 2016. At the time of inclusion in the study routine laboratory tests, cardiopulmonary exercise test, echocardiography, and right heart catheterisation were performed in all patients. During right heart catheterisation, 10 ml of coronary sinus blood was collected. Fetuin serum concentration was measured by the sandwich enzyme-linked immunosorbent assay (ELISA) with the commercially available kit.The end-point was defined as all-cause mortality during a 1.5 years follow-up. Our medical university local Institutional Review Board approved the study protocol, and all patients provided informed consent. The study was performed in accordance with the ethical standards as laid down in the 1964 Declaration of Helsinki and its later amendments. Results Patients' median age was 53.00 (46.00–58.00) years, and 91.7% were men. During the 1.5-year follow-up, 31 (43.1%) patients died. The area under the receiver operating characteristic curve indicated a good discriminatory power of fetuin (AUC: 0.917 [95% CI: 0.858–0.977]). The cut-off point for fetuin ( Conclusions Our study demonstrated that a low coronary sinus fetuin and peripheral blood sodium levels are associated with mortality patients with advanced HF accepted for HT. In addition, fetuin level, with excellent prognostic strength, allows for the risk stratification of death in analysed group of patients.

Background Previously published studies assessing the time effect of primary percutaneous intervention (PCI) on long-term clinical outcomes in an overall group of patients with acute coronary syndromes has been widely investigated. It has been suggested that night-time admission may negatively influence long-term overall mortality. Patients treated within the left main coronary artery (LMCA) belong a narrow group of high-risk procedures that require an operator and a team with high skills. Purpose The aim of the presented study was to assess the relationship between the time of pPCI (day- vs. night-time) and overall mortality among patients treated due to AMI within the LMCA. Methods This observational study was performed on 443,805 patients hospitalised due to non-ST segment elevation myocardial infarction (NSTEMI) or ST-segment elevation myocardial infarction (STEMI). Patients were prospectively enrolled between January 2006 and December 2018 in the ongoing Polish Registry of Acute Coronary Syndromes (PL-ACS). From the overall group of patients, the authors selected 5,404 patients treated within the LMCA. After taking exclusion criteria into consideration, the patients were divided according to time of PCI treatment: daytime hours (7:00 a.m.-10:59 p.m.) – 2,809 patients and night-time hours (11:00 p.m. - 6.59 a.m.) – 473 patients. Results Patients treated during night-time and daytime did not differ significantly in age (70.79 [61.52–79.73] vs. 69.73 [60.8–78.82] years, p=0.13) or gender – males (67.6% vs. 67.0%, p=0.79). Patients treated during daytime presented with significantly higher rate of STEMIs (67.2% vs. 49.9%) and lower rate of NSTEMIs (32.8% vs. 50.1%) in comparison to those treated during night-time (p Conclusions The time of pPCI (day- vs. night-time) in patients with AMI and treated within the LMCA is related to the overall 30-day and 12-month survival which is poorer in those treated during the night-time. However, this relationship was not confirmed by multiple regression analysis and was not found to be significant among other stronger predictors. Funding Acknowledgement Type of funding source: None

Background Cardiac allograft vasculopathy (CAV) is one of the main risk factors influencing graft loss and patients survival. An important element of monitoring the patient after heart transplantation (HT) is the assessment of non-invasive indicators associated with the occurrence and progression of CAV. Therefore, new noninvasive sensitive and specific tools are necessary for detecting CAV early, which may result in the modification of immunosuppressive therapy, increase in statin doses, and intensive treatment of CAV-related comorbidities. Purpose The aim of the study was to research for factors associated with occurrence of moderate to severe CAV in heart transplant recipients. Methods Our analysis included consecutive adult patients after HT with CAV who underwent routine visits in our institution between 2015–2017. Exclusion criteria included history of kidney diseases, hepatitis B and C, autoimmune diseases, chronic pancreatitis or thyroid diseases, and cerebrovascular accidents. During each visit, all patients underwent echocardiography, laboratory tests, immunosuppressive drugs serum concentration analyses, and coronary angiographies. In addition, Klotho protein concentration was measured in all patients using sandwich enzyme-linked immunosorbent assay (ELISA) with the commercially available kit. Coronary angiographies of all patients enrolled to the study were reviewed by two independent interventional cardiologists to accurately classify coronary artery lesions according to International Society for Heart and Lung Transplantation (ISHLT) guidelines. Then, patients were divided into a group with mild CAV (1) and moderate to severe CAV (2/3). The local institutional review board of the Medical University of Silesia approved the study protocol, and all patients provided informed consent. Results The final group consisted of 141 patients with CAV. The age of the patients was 60.0 (53.0–66.0) and 77.5% of them were male. The median time from HT to include in the study was 11.6 (8.5–15.0) years. The frequency of CAV 2/3 in the analysed population was 36.6%. All included patients received optimal immunosuppressive therapy consisting of a calcineurin inhibitor (tacrolimus or cyclosporin) and mycophenolate mofetil. Multivariate analysis of logistic regression showed that Klotho protein (OR = 0.719 [0.598–0.866], p Conclusions Lower Klotho and albumin levels, as well as left ventricular and left atrium dimensions are the independent factors of moderate to severe CAV presence.

Background Oxidative stress is a cause of cardiac diseases and contribute to apoptosis, cardiac remodeling, cardiac growth and repair. The end-stage heart failure (HF) is associated with ischemia-reperfusion, increased neurohumoral activity, cytokine stimulation and presence of inflammatory cells. Above factors are stimuli which generate free radicals and can induce oxidative stress in the heart and cause damage to essential myocardial structures and function. However, the role of oxidative stress in end-stage HF has not been fully understood. Purpose This study aimed to evaluate the prognostic value of the oxidative stress markers in ambulatory patients with end-stage HF awaiting heart transplantation (HT) during a 1.5 year follow-up period. Method The study was a prospective analysis of 85 optimally treated adult patients with end-stage HF, who were added to the HT waiting list at the Cardiology Department between 2015 and 2016. At the time of enrollment to the study routine laboratory tests, cardiopulmonary exercise test, echocardiography, spirometry and right heart catheterization were performed in all patients. During right heart catheterization, 10 ml of coronary sinus blood was additionally collected to determine total oxidant status (TOS) and total antioxidant capacity (TAC) levels. TOS and TAC were measured by Erel's method. The endpoint was all-cause mortality during a 1.5 years follow-up. The Medical University of Silesia's local Institutional Review Board approved the study protocol, and all patients provided informed consent. Results Median age of the patients was 53.0 (43.0–56.0) years and 90.6% of them were male. During the observation period, the mortality rate was 40%. The area under the receiver operating characteristics (ROC) curves indicated an acceptable discriminatory power of TAC (AUC: 0.780 [CI: 0.677–0.883]; sensitivity 56%, and specificity 90%); and excellent power of TOS (AUC: 0.9530 [CI: 0.9279–0.9781]; sensitivity 88%, and specificity 94%) for 1.5 years mortality. Patients with a low TAC level (≤1.10) had a significantly worse 1.5-year survival compared to the group with a high TAC level (>1.10) (1.5 year survival: 20.8% versus 75.4%; (long rank p Conclusion TAC with acceptable prognostic power and TOS with excellent prognostic power allows assessment of the prognosis in end-stage HF during a 1.5 year follow-up period.

Background Despite advances in the treatment, end-stage heart failure (HF) is a disease with a severe prognosis, showing an annual mortality rate of 30 to 50%. Due to a poor prognosis in this population of patients, it is necessary to accurately stratify the risk of death, including simple and effective prognostic markers. Objective This study aimed to determine biomarkers associated with mortality in patients with end-stage HF. Material and methods The study was a prospective analysis of optimally treated patients with end-stage HF, who were hospitalised at the Cardiology Department between 2016 and 2018. At the time of enrollment to the study routine laboratory tests, cardiopulmonary exercise tests, echocardiography and right heart catheterization were performed in all patients. Human Interleukin 33 (IL-33) and IL-1 Receptor Like 1 (IL1RL1) were measured by sandwich enzyme-linked immunosorbent assay (ELISA) with the commercially available kit (Human Il-33 and IL1RL1 ELISA kit, SunRedBio Technology Co, Ltd, Shanghai, China). Plasma concentration of N-terminal brain natriuretic peptide (NT-proBNP) was measured using a commercially available kit (Human NTproBNP ELISA kit, Roche Diagnostics, Mannheim, Germany). The endpoint was all-cause mortality during a one-year follow-up. The Medical University of Silesia's local Institutional Review Board approved the study protocol, and all patients provided informed consent. Results The final study group consisted of 282 patients (87.6% males, median age 57.0 years). One-year mortality rate in the analysed population was 28%. In a multivariate analysis, independent risk factors of death included NT-proBNP [Hazard Ratio (HR) 1.056 (95% Confidence Interval (CI): 1.024–1.089); P Conclusions Our study showed that lower sodium and IL-33 levels, as well as higher NT-proBNP and IL1RL1 levels are associated with an increased risk of death in patients with end-stage HF during a one-year follow-up.

Introduction Cardiac allograft vasculopathy (CAV) is a major threat to long-term survival after heart transplantation (HT). The frequency of CAV is estimated to be 8% at 1 year after HT, 30% at the 5-year follow-up, and as high as 50% within 10 years after the procedure. Therefore, it is necessary to select those factors that are closely associated with the presence of CAV and facilitate the proper, fast and minimally invasive diagnosis of this disease. Purpose The aim of this study was determine risk factors associated with CAV detection in patients after HT. Material and methods We analyzed 299 consecutive patients after HT who underwent routine visits in our institution between 2015 and 2017. During the visit, echocardiography, routine coronary angiography, laboratory tests and immunosuppressive drug serum concentrations were performed in all patients. In addition, 10 ml of peripheral blood was collected to determine human interleukin 33 (IL-33) and IL-1 Receptor Like 1 (IL1RL1). IL-33 and IL1RL1 concentrations were measured by sandwich enzyme-linked immunosorbent assay (ELISA) with the commercially available kit. The diagnosis of CAV was based on the results of coronary angiography and defined according to the current International Society for Heart and Lung Transplantation (ISHLT) criteria.The Medical University Local Institutional Review Board approved the study protocol, and all patients provided informed consent. Results Patients' median age was 59.00 (45.00–66.00) years, and 74.2% were men. The median time from HT to study inclusion was 9.03 (6.02–13.01) years. The frequency of CAV according to the ISHLT criteria in the analysed population was 47.5%. At the time of enrolment all patients were receiving immunosuppressive therapy with calcineurin inhibitor and mycophenolate mofetil, and were free from acute rejection (diagnosed either by echocardiography or biopsy), clinical signs of infection or symptoms of acute heart failure. Multivariate analysis using logistic regression confirmed that IL-33 OR 0.958 (0.944–0.972), p Conclusions Lower IL-33 and higher IL1RL1 serum concentrations, as well as donor age, left ventricular diastolic dimension and time from HT to blood collection are independently associated with CAV. This study provides non-invasive, low-cost, and simple indicators for CAV detection. Funding Acknowledgement Type of funding source: Public Institution(s).

Background In 2017 a nation-wide system of managed care for MI survivors comprising acute treatment of MI, cardiac rehabilitation and cardiac ambulatory care within one year following MI was implemented in Poland. The managed care programme (MCP) was proved to be related to lower risk of all-cause death. The goal of the analysis was to assess the effectiveness of MCP in patients discharged from university, district, municipal and non-public hospitals. Methods The database of survivors of acute MI discharged from hospital from October 1, 2017 to December 31, 2018 was analyzed. Patients who died within 10 days after discharge were excluded from the analysis. The primary end-point was defined as death from any cause. Propensity-Score Matching using nearest neighbor matching was used to form comparable groups of patients participating and not participating in the MCP. The Cox proportional hazard regression analysis was used to assess the relation between MCP and the overall mortality. Results MCP was implemented in the first stage in 48 hospitals spread around the country (about 34% of all hospitals treating acute MI patients in Poland). Among them 14 were university, 20 district, 8 municipal and 6 nonpublic hospitals. Out of 34064 patients discharged from hospitals with MCP implemented 10404 patients (30.5%) participated in MCP. They were matched with 10404 patients not participating in the MCP. About 24% of the analyzed patients were discharged from university hospitals, 42% from district hospitals, 20% from nonpublic, 14% from municipal and other hospitals. During 326.3±134.8 days of follow-up 1062 patients died (4.4% vs. 6.5% of patients participating and not participating in the MCP; p Conclusion The implemented in Poland nation-wide system of managed care for MI survivors is related to improved survival in all hospital settings.

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).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.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.The survival to hospital discharge after OHCA could be predicted by the GCS score on hospital admission.

Funding Acknowledgements Institute of Cardiology statutory grant (grant no.: 2.30/VII/13) Background Atrial fibrillation (AF) and heart failure (HF) often co-exist and influence each other. The presence of AF is often regarded as a marker of HF severity. Moreover, AF in cardiac resynchronization therapy (CRT) recipients hinders the CRT effectiveness in HF treatment by the reduction of the percentage of biventricular paced beats (BiVp%). Sinus rhythm (SR) restoration makes CRT more effective in HF treatment which may protect AF recurrence. Purpose To establish the effectiveness of electrical external cardioversion (EEC) in CRT patients with long-standing persistent AF or permanent, pre-treated with amiodarone. Methods The population of the study comprised of the Pilot-CRAfT study participants (NCT01850277), that is patients with CRT, long-standing persistent or considered as permanent AF and BiVp ≤ 95% who were randomly assigned to the "rhythm control" or the "rate control" strategy. The inclusion criteria included an AF paroxysm lasting at least 6 months. Both treatment arms received amiodarone beginning with the loading dose. Subsequently, patients assigned to the rhythm control strategy underwent electrical cardioversion. Rate control strategy included pharmacotherapy and atrioventricular node ablation, as needed. The follow up visit was performed 3 months after the enrolment visit. The EEC effectiveness, an AF recurrence within the 3 month period, BiVp% changes, the EEC parameters and the EEC related complications were analysed. Results Out of 48 participants enrolled in the Pilot-CRAfT study, 25 patients were assigned to the rhythm control arm. The mean age of the rhythm control arm patients was 69,5 years , the mean left ventricular ejection fraction was 30,6% , the mean left atrium diameter was 53 mm and the median duration of persistent AF was 16 months. SR was obtained in 12 out of 20 (60%) patients who underwent the EEC . On the 3 month visit 8 patients remained in SR (40%). In patients with an AF paroxysm lasting less than 1 year the success rate was 100% vs 50% in the AF lasting 1 year at least (p = 0,11 ). After 3 months, SR remained in 100% vs 25% of patients, respectively (p =0,015.). The effectiveness of anterior-posterior EEC electrodes placement was 20% and it was 71% for the anterior-lateral patch location . The EEC resulted in significant BiVp% rise - also in the whole intention-to-treat (ITT) group: 88,58% before the EEC vs 96,68% after the EEC (p = 0,002). No severe adverse events of the EEC were observed. Conclusions The electrical cardioversion of persistent atrial fibrillation lasting more than 6 months in patients with severe HF and treated with CRT is characterised by modest success rate, even after the amiodarone pre-treatment. However, the ECC ensures significant rise in BiVp% close to 97%, even in the whole EEC group based on the ITT principle. The AF paroxysm duration

Objectives We sought to determine the 1-year clinical follow-up in patients treated with the thin strut (71 μm) bioabsorbable polymer-coated sirolimus-eluting stent (BP-SES) vs durable coating everolimus eluting stent (DP-EES) in daily clinical routine. Background Presence of durable polymers may be associated with late/very late stent thrombosis occurrence and the need for prolonged dual antiplatelet therapy. Bioabsorbable polymers may facilitate stent healing, thus enhancing clinical safety. Methods Interventional Cardiology Network Registry is a prospective, multicenter, observational registry of 21,400 consecutive patients treated with PCI since 2010. We analyzed 4,670 patients treated with either a BP-SES (ALEX, Balton, Poland) or DP-EES (XIENCE, Abbott, USA) with available 1-year clinical follow-up using propensity-score matching. Outcomes included target vessel revascularization (TVR) as efficacy outcome and all cause death, myocardial infarction (MI), and definite/probable stent thrombosis as safety outcomes. Results After propensity score matching, 1,649 patients treated with BP-SES and 1,649 patients treated with DP-EES were selected. Procedural and clinical characteristics were similar between both groups. There was no significant difference between tested groups in in-hospital mortality. One-year follow-up demonstrated comparable efficacy outcome, TVR (BP-SES 5.9% vs DP-EES 4.6% P = 0.45), as well as comparable safety outcomes, all cause death, MI and definite/probable stent thrombosis. Conclusions In this multicenter registry, the BP-SES thin strut biodegradable polymer-coated sirolimus-eluting stent demonstrated comparable clinical outcomes at 1-year after implantation to the DP-EES. These data support the relative safety and efficacy of DP-SES in a broad range of patients undergoing percutaneous coronary intervention.

Aim: Albumin-to-globulin ratio (AGR) is emerged as a marker of impaired prognosis. We determined the predictive value of AGR in patients with heart failure with reduced ejection fraction (HFrEF). Methodology: 999 patients with HFrEF were enrolled. Rates of 1-year all-cause mortality were compared between AGR quartiles (Q). Moreover, multivariate survival analysis in Cox's regression model and receiver operating characteristic analyses were performed. Results: 90-day and 1-year mortality was the highest in AGR Q1. AGR was an independent predictor of 90-day and 1-year mortality. Receiver operating characteristic analysis revealed moderate diagnostic value in predicting 90-day (AGR cutoff

Methods: 1213 patients were selected from institutional databases, 761 and 452 in CABG and PCI group respectively. Only the subjects with left ventricle ejection fraction ≤ 35% and multivessel coronary artery disease were included to the study. The primary outcome measure was long-term all-cause death, the secondary outcomes were recurrent myocardial infarction, urgent repeat revascularization and stroke. Propensity Score-Based Adjusted Survival Curves were used for revascularization methods comparison. Results: Survival rates were similar in both groups (HR, 0.91; 95% CI, 0.65-1.28; p=0.59). Recurrent myocardial infarction was observed significantly less often in the CABG group (HR, 0.44; 95% CI, 0.26-0.74; p=0.002). Repeat urgent revascularization was less frequent in the CABG group (HR, 0.50; 95% CI, 0.30-0.84; p=0.008). The rate of stroke did not differ between the groups (HR, 1.17; 95% CI, 0.62-2.22; p=0.62). Conclusions: In patients with HFrEF and multivessel CAD revascularization both with CABG and PCI resulted in similar survival rates. PCI is associated with increased risk of recurrent MI and urgent repeat revascularization, whereas the risk of stroke is similar in both methods.

Introduction The biodegradable polymer drug-eluting stents were developed to improve vascular healing. However, further data are needed to confirm the safety and efficacy of these stents in patients with acute myocardial infarction (AMI). Aim We sought to determine the 1-year clinical follow-up in patients with AMI treated with a thin strut biodegradable polymer-coated sirolimus-eluting stent (BP-SES) versus a durable coating everolimus-eluting stent (DP-EES). Material and methods We analyzed patients with AMI (STEMI and NSTEMI) treated with either a BP-SES (ALEX, Balton, Poland, n = 886) or DP-EES (XIENCE, Abbott, USA, n = 1054) with available 1-year clinical follow-up using propensity score matching. Outcomes included target vessel revascularization (TVR) as the efficacy outcome and all-cause death, myocardial infarction, and definite/probable stent thrombosis as safety outcomes. Results After propensity score matching 672 patients treated with BP-SES and 672 patients treated with DP-EES were selected. Procedural and clinical characteristics were similar between the groups. In-hospital mortality was similar in both tested groups. One-year follow-up demonstrated comparable efficacy outcome TVR (BP-SES 7.1% vs. DP-EES 5.2%, p = 0.14), as well as similar safety outcomes of all-cause death, myocardial infarction, and definite/probable stent thrombosis. Conclusions The thin-strut biodegradable polymer coated sirolimus-eluting stent demonstrated comparable clinical outcomes at 1 year after implantation to the DP-EES. These data support the relative safety and efficacy of BP-SES in AMI patients undergoing percutaneous coronary intervention.

INTRODUCTION During the last decade, there has been an increased awareness of sex differences in the clinical characteristics, management, and mortality in myocardial infarction. Many previous studies have found that women with ST-elevation myocardial infarction (STEMI) have a poorer baseline risk profile, are less intensively treated, and have worse outcomes. OBJECTIVE To evaluate whether sex disparities in STEMI have changed in recent years. METHODS This is a retrospective analysis of data on 111 148 STEMI patients enrolled in the Polish Registry of Acute Coronary Syndromes between 2005 and 2011. Temporal trends in the clinical presentation, treatment strategies, and mortality rates between men and women are compared. RESULTS Throughout the study, women were, on average, older than men, and more frequently presented with hypertension, diabetes, or obesity. These differences showed a tendency for narrowing. The percentage of smokers increased in both sexes. Despite a reduction in prehospital delays, they remained longer in women. Sex differences in prehospital cardiac arrest and cardiogenic shock at admission disappeared. In 2011, women were still less likely to undergo coronary angiography with subsequent revascularization, but it was mainly driven by patients older than 70 years of age who also had a higher in-hospital mortality. Despite the greater relative risk reductions, the crude mortality rates remained significantly higher in women. Female sex was not an independent predictor of mortality. CONCLUSION Sex differences in STEMI patients were narrowing from 2005 to 2011 in Poland. However, more attention needs to be focused on increasing smoking prevalence, the longer times from symptoms onset to hospital admission in women and the lower frequencies of the use of an invasive treatment strategy in older women, and their worse in-hospital outcomes.

Remote Monitoring in Real-World CohortBackground Randomized controlled trials demonstrate that remote monitoring (RM) of implantable cardioverter–defibrillators (ICDs) and cardiac resynchronization therapy devices (CRT-Ds) may improve quality of care and prognosis in heart failure (HF) patients. However, the impact of RM on long-term mortality in a real-world cohort is still not well examined. Methods and Results This study was designed as a matched cohort study based on the COMMIT-HF trial––a single-center, ongoing prospective observational registry (NCT02536443). Complete patient demographics, medical history, in-hospital results, hospitalizations, and mortality data were collected based on institutional registries and healthcare providers’ records. Patients were divided into 2 groups based on RM presence and matched by means of propensity scores according to clinical characteristics. The primary endpoint of this study was the long-term all-cause mortality. Out of 1,429 consecutive patients, 822 patients with a first implantation of an ICD/CRT-D were included in the analysis. The final matched study population contained 574 patients in RM and in a control group. Although demographic and echocardiographic parameters as well as pharmacological treatments were similar in both groups, a significantly lower 1-year mortality was detected in the RM group (2.1% vs. 11.5%, P < 0.0001). This was also maintained during a 3-year follow-up (4.9% vs. 22.3%, P < 0.0001). Multivariate analysis showed that RM was associated with an improved prognosis (hazard ratio 0.187, 95% confidence interval 0.075–0.467, P = 0.0003). Conclusion RM of HF patients with ICDs/CRT-Ds significantly reduced long-term mortality in a real-world clinical condition.

Background The latest guidelines from the American Association of Clinical Endocrinologists (AACE) and the American College of Endocrinology (ACE) introduced a new “ultra-high risk” category of patients, for whom a low-density lipoprotein cholesterol (LDL-C) level Purpose Based on the above, we aimed to identify the proportion of patients, who are at ultra-high/extremely-high cardiovascular (CV) risk. Method Finally, we analyzed the data of 19,781 consecutive patients included in theHyperlipidaemia Therapy in the tERtiary Cardiological cEnTer (TERCET) Registry admitted to the Polish tertiary cardiovascular centre between 2006 and 2018. Among them, there were 7,319 patients admitted with ACS: 3,085 due to ST-segment elevation myocardial infarction (STEMI), 2,256 due to non-ST-segment elevation myocardial infarction (NSTEMI), and 1,978 due to unstable angina (UA), as well as 12,462 due to stable angina (SA). According to the European Society of Cardiology (ESC), all patients included in the Registry are at very high CV risk. All of the patients included in the registry underwent coronary angiography during the hospital stay. On the basis of the multivariate analysis, we aimed at determining the subgroup of the patients with the most unfavourable 12-month outcomes and therefore to indicate the risk factors responsible for extremely-high CV risk. Results According to the results of the multivariate analysis performed with stepwise backward regression, we identified the following risk factors: LVEF75 years (OR=1.84, 95% CI: 1.33–2.55), atrial fibrillation (OR=1.81, 95% CI: 1.45–2.25), acute MI at admission (OR=1.56, 95% CI: 1.26–1.95), multivessel CAD (OR=1.40, 95% CI: 1.15–1.72), prior MI (OR=1.31, 95% CI: 1.07–1.60) and lower body-mass index (OR=1.02 per 1 kg/m2+ less, 95% CI: 1.00–1.04) that might help to define the group of very high risk patients, who should be considered as of extremely-high cardiovascular risk (all p Multivariate analysis results Conclusions To our best knowledge, the presented study is the first such an analysis conducted on such a large population of very-high cardiovascular risk patients gathered in the registry of secondary cardiovascular prevention. In very-high cardiovascular risk patients, potential risk factors were identified that might help to establish the group of individuals at extremely high CV risk what contributes to higher 12-month mortality.

Background Heart failure (HF) is one of the most important global health problems in developed and ageing societies. Coronary artery disease (CAD) is the most common etiologic factor, related to poor outcomes. Data on CAD management in HF is scarce, especially when addressing subpopulations often omitted in randomized trials, such as the elderly. Purpose With a large cohort of HF patients (n=2730) we have decided to assess the clinical profile, treatment modalities and outcomes in elderly patients undergoing percutaneous coronary intervention (PCI). Methods We analyzed a large single-center all-comer registry of HF patients (left ventricular ejection fraction LVEF≤35%) treated in a large-volume cardiovascular center (2009–2015). Acute coronary syndromes on admission were excluded. Patients with ischemic etiology were selected for further analysis (n=1703) and subsequently divided into the elderly (≥75 y.o., n=346) and young ( Results The elderly group had understandably a worse clinical profile (mean age 79,1±3,5 vs 61,2±8,2, p Coronary angiography was performed frequently in both groups (78,6 vs 74,9%, p=0,15). Significant lesions were observed in 73,5 and 65,0% of cases respectively (p=0,008). The elderly were insignificantly less frequently qualified for CABG (9,0 vs 12,5%, p=0,17). Proportion of patients qualified for medical management of CAD was similar (23,5 vs 20,7%, p=0,40). PCI was performed frequently in both groups (59,5 vs 57,9%, p=0,69), often as multi-vessel procedures (34,4 vs 32,4%, p=0,67). There was a trend towards more complete revascularization in the younger patients (50,0 vs 59,5%, p=0,06). 12-month all-cause mortality was significantly higher in the elderly (20,3 vs 7,8%, p Conclusions The analysis shows that PCI is a viable treatment option in the elderly population and when indicated can be performed safely, with good short and long term results. Interventions such as ICD implantation or optimal medical therapy of HF should always be considered. Acknowledgement/Funding None

Background Almost 50% of all ACS in young women are NSTEMI and UA. Due to the type of ACS we observed differences in the symptomatology, treatment and outcomes. The aim was to evaluate the differences in the clinical course and prognosis in young women aged ≤45 years with NSTEMI vs. UA. Methods We compared 1143 women aged ≤45y.o. with acute cardiac syndromes: 51% NSTEMI, 49% UA from the PL-ACS registry between 2007 - 2014. Results Chest pain was predominant in both group, with a higher incidence in NSTEMI group (91.7% vs. 84.7, p=0.0002). UA group was older (42y.o. vs. 41y.o p=0.003), more often presents atypical symptoms (8.0% vs. 1.5%, p Table 1. Mortality rate in studied group NSTEMI group (N=580) UA group (N=563) P 30-day mortality 1.60% 0.70% 0.1799 6-month mortality 2.20% 0.90% 0.0662 One year mortality 3.10% 1.60% 0.0940 Conclusions Clinical course of ACS in young women is different regardless of the type of ACS (NSTEMI/UA) however with no difference in mortality rate. Typical symptoms increases the probability of unstable angina (UA) 2.8 times (p=0.0003). In the UA group, ACS was rarely related to circumflex and diagonal branch with more frequent in-stent restenosis. PCI delay in patients with UA results from a longer door-to-ballon time.

Introduction A minimal delay from symptom onset to reperfusion therapy is essential in the management of acute myocardial infarction (AMI). The patient's response to initial symptoms (patient delay) substantially affects the delay. Nevertheless, predictors of patient-related delays are less clear. The aim of the study was to compare knowledge and awareness of heart attack symptoms and reactions to it in a general Polish population. Methods In this cross-sectional study, 1 376 persons aged 18 years or older enrolled in an Internet survey (computer assisted web interview, CAWI). Heart attack knowledge, self-efficacy for recognizing and responding to heart attack symptoms, and perceived risk for a future heart attack were measured. Primary exclusion criteria were: prior MI or family history of MI. The survey was carried out as a part of the nationwide “Heart attack – time is life” Campaign. Results Based on the Polish Registry on Acute Coronary Syndromes (PL-ACS) the median total ischemic time in Poland is 260 minutes, whereas the median patient delay is 142 minutes. The main factors associated with long time delays include interhospital transfers, symptoms presentation during the night, age >65 years, inhabitants of rural areas, diabetes mellitus, first-ever MI, female sex. The survey demonstrated that 73.8% of respondents recognize that chest pain may be associated with MI, but only 22.2% of them would call the emergency medical services. Age-, sex-, income-, and education-related responses are depicted in the Figure. Only 23% of these respondents would make the call immediately, whereas 31.7% would wait at least 3–4 hours (in some cases event until the next day). 66.4% of the surveyed population would ignore the chest pain main reason being “nothing serious” or “a result of extreme emotions”. Notwithstanding, the majority of the surveyed population is aware of the seriousness of the AMI-related complications (heart failure, disability, rehospitalizations, death). Conclusions These findings highlight the urgent need to develop effective, tailored campaigns to close the knowledge gap and, primarily, to educate the Polish society about the correct response to chest pain. Young age, higher education, and high income were not predictors of common sense and correct responses.

Background The latest guidelines from the American Association of Clinical Endocrinologists (AACE) and the American College of Endocrinology (ACE) introduced a new “ultra-high risk” category of patients, for whom a low-density lipoprotein cholesterol (LDL-C) level Purpose Therefore we aimed at identification of the risk factors in patients after acute myocardial infarction (MI), which increased the risk most, and might help to define the group of individuals at extremely high cardiovascular (CV) risk. Methods We analyzed consecutive patients included in the TERCET Registry admitted to the Polish tertiary cardiovascular centre due to MI between 2006 and 2018. According to the guidelines of the European Society of Cardiology (ESC), all patients included in the analysis are considered as of very high CV risk. All patients included in the registry underwent coronary angiography during the hospital stay. On the basis of multivariate analysis, we determined the subgroup of patients with the most unfavourable 12-month outcome (all-cause mortality). Results Finally, 4,562 patients admitted due to STEMI or NSTEMI and discharged from our centre were included in the analysis. According to the results of multivariate analysis performed with stepwise backward regression model, the following risk factors in patients after MI: LVEF75 years (OR=1.91, 95% CI: 1.55–2.35), lack of PCI of culprit vessel (OR=1.66, 95% CI: 1.26–2.20), multivessel CAD (OR=1.60, 95% CI: 1.30–1.99), atrial fibrillation (OR=1.53, 95% CI: 1.21–1.94), diabetes mellitus (OR=1.34, 95% CI: 1.11–1.64), increased LDL-C level (OR=1.09 per 1 mmol/L, 95% CI: 1.01–1.19) and increased creatinine level (OR=1.04 per 10 μmol/L, 95% CI: 1.04–1.05), might help to define the group of patients at extremely-high cardiovascular risk (all p Next, the effect of the combination of the aforementioned risk factors will be investigated, and SCORE applied for patients in secondary prevention after MI will be prepared. Multivariate analysis results Conclusions To our knowledge, the presented study is the first such an analysis conducted on the population of patients after myocardial infarction gathered in the registry of secondary cardiovascular prevention. In patients after MI, potential risk factors were identified that might help to define the group of patients at ultra-high/extremely-high risk, what might contribute to significantly higher 12-month mortality.
