ObjectiveInflammation has emerged as a new treatment target in patients with coronary artery disease and inflammation seems to play an important role in ischaemia/reperfusion injury that follows ST-elevation myocardial infarction (STEMI). We aimed to explore the role of acute and sustained interleukin 6 (IL-6) signalling, including soluble IL-6 receptor (IL-6R), with regard to infarct size, adverse remodelling and future cardiovascular events in patients with STEMI.MethodsWe included 269 patients with first-time STEMI, symptom duration <6 hours and treated with percutaneous coronary intervention. Blood sampling and cardiac MRI were performed in the acute phase and after 4 months. Clinical events and all-cause mortality were registered during 12-month and 70-month follow-up, respectively.ResultsIL-6 levels above median at all sampling points were significantly associated with increased infarct size and reduced left ventricular ejection fraction (LVEF). IL-6 levels in the highest quartile were at all sampling points associated with an increased risk of having an adverse clinical event during the first 12 months and with long-term all-cause mortality. IL-6R was not associated with infarct size, LVEF, myocardial salvage or long-term all-cause mortality.ConclusionAcute and sustained elevation of IL-6 measured 4 months after STEMI were associated with larger infarct size, reduced LVEF and adverse clinical events including all-cause mortality. The results add important information to the sustained role of inflammation in patients with STEMI and IL-6 as a potential target for long-term intervention.Trial registration numberNCT00922675.

Background. The relevance of neutrophil extracellular traps (NETs) in acute ST-elevation myocardial infarction (STEMI) is unclear. We explored the temporal profile of circulating NET markers and their associations to myocardial injury and function and to adverse clinical events in STEMI patients. Methods and Results. In 259 patients, blood samples were drawn before and after PCI, on day 1, and after 4 months. Double-stranded deoxyribonucleic acid (dsDNA) and myeloperoxidase-DNA (MPO-DNA) were measured in serum by a nucleic acid stain and ELISA. Cardiac magnetic resonance imaging assessed microvascular obstruction (MVO), area at risk, infarct size, myocardial salvage index, left ventricular ejection fraction (LVEF), and change in indexed left ventricular end-diastolic volume (LVEDVi). Clinical events were registered after 12 months. dsDNA and MPO-DNA levels were highest before PCI, with reduced levels thereafter (all p≤0.02). Patients with high vs. low day 1 dsDNA levels (>median; 366 ng/ml) more frequently had MVO, larger area at risk, larger infarct size acutely and after 4 months, and lower myocardial salvage index (all p<0.03). Moreover, they had lower LVEF acutely and after 4 months, and larger change in LVEDVi (all p≤0.014). High day 1 dsDNA levels also associated with risk of having a large infarct size (>75th percentile) and low LVEF (≤49%) after 4 months when adjusted for gender, time from symptoms to PCI, and infarct localization (OR 2.3 and 3.0, both p<0.021), and patients with high day 1 dsDNA levels were more likely to experience an adverse clinical event, also when adjusting for peak troponin T (hazard ratio 5.1, p=0.012). No such observations were encountered for MPO-DNA. Conclusions. High day 1 dsDNA levels after STEMI were associated with myocardial infarct size, adverse left ventricular remodeling, and clinical outcome. Although the origin of dsDNA could be discussed, these observations indicate a potential role for dsDNA in acute myocardial ischemia. This trial is registered with S-08421d, 2008/10614 (Regional Committee for Medical Research Ethics in South-East Norway (2008)).

Abstract Funding Acknowledgements Type of funding sources: Foundation. Main funding source(s): The Danish Heart Foundation Background In acute heart failure (AHF), low systolic blood pressure (SBP) has been associated with poor outcome. Less is known of the risk related to normal versus elevated SBP and interaction with left ventricular ejection fraction. Purpose The aim of the present study was to assess the association between baseline SBP and short- and long-term outcome in a large cohort of AHF-patients. Methods A pooled cohort of four randomized controlled trials investigating the vasodilator serelaxin versus placebo in patients admitted with AHF and an SBP from 125 to 180 mmHg. Endpoints were 180-day all-cause mortality and a short-term composite endpoint (worsening heart failure, all-cause mortality or hospital readmission for HF through Day 14). Left ventricular ejection fraction (LVEF) was categorized into HFrEF (&lt;40%) and HFpEF (= &gt;40%). Multivariable Cox regression was used and adjusted for age, sex, baseline body mass index, HFrEF, serum estimated glomerular filtration rate, allocated treatment (placebo/serelaxin), diabetes mellitus, ischemic heart disease, and atrial fibrillation/flutter. Measurements and Main Results A total of 10.533 patients with a mean age of 73 (±12) years and median SBP of 140 (130-150) mmHg were included within mean 8.2 hours from admission. LVEF was assessed in 8493 (81%), and of these, 4294 (51%) had HFrEF. Increasing SBP as a continuous variable was inversely associated with 180-day mortality (HRadjusted: 0.93 [0.88-0.98], p = 0.004 per 10 mmHg increase) and with the composite endpoint (HRadjusted: 0.90 [0.85-0.95], p &lt; 0.0001 per 10 mmHg increase). A significant interaction was observed regarding LVEF, revealing that SBP was not associated with mortality in patients with HFpEF  (HRadjusted: 1.01 [0.94-1.09], p = 0.83 per 10 mmHg increase), but SBP was associated with increased mortality in HFrEF (HRadjusted: 0.80 [0.73-0.88], p &lt; 0.001 per 10 mmHg increase) (Figure). Conclusions Elevated SBP is independently associated with favorable short- and long-term outcome in AHF-patients. The association between SBP and mortality was, however, not present in patients with preserved LVEF. Abstract Figure. Survival plots by SBP and LVEF

AbstractBoth acute myocardial infarction complicated by ventricular tachyarrhythmias (AMI–VTA) and electrical storm (ES) represent life-threatening clinical conditions. However, a direct comparison of both sub-groups regarding prognostic endpoints has never been investigated. All consecutive implantable cardioverter-defibrillator (ICD) recipients were included retrospectively from 2002 to 2016. Patients with ES apart from AMI (ES) were compared to patients with AMI accompanied by ventricular tachyarrhythmias (AMI–VTA). The primary endpoint was all-cause mortality at 3 years, secondary endpoints were in-hospital mortality, rehospitalization rates and major adverse cardiac event (MACE) at 3 years. A total of 198 consecutive ICD recipients were included (AMI–VTA: 56%; ST-segment elevation myocardial infarction (STEMI): 22%; non-ST-segment myocardial infarction (NSTEMI) 78%; ES: 44%). ES patients were older and had higher rates of severely reduced left ventricular ejection fraction (LVEF) < 35%. ES was associated with increased all-cause mortality at 3 years (37% vs. 19%; p = 0.001; hazard ratio [HR] = 2.242; 95% CI 2.291–3.894; p = 0.004) and with increased risk of first cardiac rehospitalization (44% vs. 12%; p = 0.001; HR = 4.694; 95% CI 2.498–8.823; p = 0.001). This worse prognosis of ES compared to AMI–VTA was still evident after multivariable adjustment (long-term all-cause mortality: HR = 2.504; 95% CI 1.093–5.739; p = 0.030; first cardiac rehospitalization: HR = 2.887; 95% CI 1.240–6.720; p = 0.014). In contrast, the rates of MACE (40% vs. 32%; p = 0.326) were comparable in both groups. At long-term follow-up of 3 years, ES was associated with higher rates of all-cause mortality and rehospitalization compared to patients with AMI–VTA.

Vasodilator stress cardiac magnetic resonance (stressCMR) has shown robust diagnostic and prognostic value in patients with known or suspected chronic coronary syndrome (CCS). However, it is unknown whether integration of stressCMR with clinical variables in a simple clinical-imaging score can straightforwardly predict all-cause mortality in this population. We included 6187 patients in a large registry that underwent stressCMR for known or suspected CCS. Several clinical and stressCMR variables were collected, such as left ventricular ejection fraction (LVEF) and ischemic burden (number of segments with stress-induced perfusion defects (PD)). During a median follow-up of 5.56 years, we registered 682 (11%) all-cause deaths. The only independent predictors of all-cause mortality in multivariable analysis were age, male sex, diabetes mellitus (DM), LVEF and ischemic burden. Based on the weight of the chi-square increase at each step of the multivariable analysis, we created a simple clinical-stressCMR (C-CMR-10) score that included these variables (age ≥ 65 years = 3 points, LVEF ≤ 50% = 3 points, DM = 2 points, male sex = 1 point, and ischemic burden > 5 segments = 1 point). This 0 to 10 points C-CMR-10 score showed good performance to predict all-cause annualized mortality rate ranging from 0.29%/year (score = 0) to >4.6%/year (score ≥ 7). The goodness of the model and of the C-CMR-10 score was separately confirmed in 2 internal cohorts (n > 3000 each). We conclude that a novel and simple clinical-stressCMR score, which includes clinical and stressCMR variables, can provide robust prediction of the risk of long-term all-cause mortality in a population of patients with known or suspected CCS.

Abstract Aims Longitudinal systolic function may integrate information on aortic stenosis (AS) natural history and cardiac comorbidities with potential prognostic implications. We explored the impact of tissue Doppler imaging (TDI)-derived longitudinal systolic function defined by the peak systolic average of lateral and septal mitral annular velocities (average S’) among symptomatic patients with severe AS undergoing transcatheter aortic valve implantation (TAVI). Methods and results 297 unselected patients with severe AS undergoing TAVI from January 2017 to December 2018 at three European centres, with available average S′ at preprocedural echocardiography were retrospectively included. The primary endpoint was the Kaplan Meier estimate of all-cause mortality. After a median 18 months (IQR 12–18) follow-up, 36 (12.1%) patients died. Average S′ was associated with all-cause mortality (per 1 cm/s decrease: HR: 1.29, 95% CI: 1.03–1.60, P = 0.025), with a best cut-off of 6.5 cm/s. Patients with average S′ &lt;6.5 cm/s (55.2% of the study population) presented characteristics of more advanced left ventricular remodelling and functional impairment along with higher burden of cardiac comorbidities, and experienced higher all-cause mortality (17.6% vs. 7.5%, P = 0.007) also when adjusted for in-study outcome predictors (adj-HR: 3.33, 95% CI: 1.25–8.90, P = 0.016). Results were consistent among patients with preserved ejection fraction, normal-flow AS, high-gradient AS and in those without left ventricular hypertrophy. Conclusions Longitudinal systolic function assessed by average S’ is independently associated with long-term all-cause mortality among unselected patients with symptomatic severe AS undergoing TAVI. In this population, an average S′ below 6.5 cm/s best defines clinically meaningful reduced longitudinal systolic function and may aid clinical risk stratification.

Introduction: Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice and is a significant risk factor for ischemic stroke and death. Digitalis has been used for more than 200 years to treat heart conditions, including AF, and its use remains controversial due to uncertain long-term morbidity and mortality. Methods: We conducted a cohort study of hospitalized patients with AF assessing the effects of digoxin on long-term all-cause mortality. Patients were divided into two groups: with and without heart failure (HF). We performed multivariable Cox regression analysis to assess hazard ratios (HR) for all-cause mortality depending on digoxin treatment and used propensity score matching to adjust for differences in background characteristics between treatment groups. Results: Among 2179 consecutive patients hospitalized with AF, the median age was 73 ± 14, and 52.5% of patients were male, 49% had HF, and 18.8% were discharged on digoxin. Median left ventricular ejection fraction in the whole cohort was 60 (IQR 40-65). Among patients with HF, 34.5% had preserved, 17.3% had mid-range and 48.1% had reduced left ventricular ejection fraction. The mean follow-up time was 3 ± 2.05 years. In patients without HF there was a statistically significant increased mortality in the digoxin subgroup after propensity score matching (HR = 2.23, 95% CI 1.42-3.51, p < 0.001). In contrast, in patients with HF, there was no difference in mortality between the treatment groups (p = 0.92). Conclusions: Digoxin use in our study was associated with increased mortality in patients with AF and without concomitant HF.

Abstract Background Soluble ST2, a member of the IL-1 receptor family, seems to be associated with adverse outcome in acute myocardial infarction and heart failure (HF), and is suggested to be involved in left ventricular (LV) remodelling. Purpose To elucidate a possible role of ST2 in LV injury, remodelling and prognosis in ST-elevation myocardial infarction (STEMI) patients. The main objectives of the study were to investigate whether circulating ST2 levels were associated with infarct size, LV function, adverse remodeling and clinical outcome in a cohort of patients with STEMI. Methods 270 patients with clinically stable first-time STEMI treated with primary percutaneous coronary intervention (PCI) were included. Blood samples were drawn before and immediately after the PCI procedure, at day 1 (median 18.3 hours after PCI) and after 4 months. Cardiac magnetic resonance (CMR) was performed in the acute phase and after 4 months. Clinical events and all-cause mortality were registered during 12 months' and 70 months' follow-up, respectively. A composite endpoint was defined as death, MI, unscheduled revascularisation >3 months after the index infarction, rehospitalisation for HF or stroke. Associations between ST2 and CMR parameters and clinical events were evaluated with linear regression and logistic regression, respectively. Results There was a significant increase in ST2 levels from the PCI procedure to day 1 with a subsequent decline from day 1 to 4 months in the POSTEMI cohort. Patients with high ST2 levels (>median) at all sampling points during hospitalisation had significantly larger infarct size, lower myocardial salvage, lower LVEF, larger increase in EDV and higher frequency of MVO. After adjustment for relevant clinical variables, peak CRP and peak troponin T, ST2 measured at day 1 remained associated with infarct size (β 2.0 per SD of ST2, p<0.001) and LVEF (β −1.8 per SD of ST2, p=0.02) at 4 months. High levels of ST2 measured at day 1 (>75th percentile) were associated with increased risk of having an adverse clinical event during the first year and with long-term all-cause mortality (Figure). High levels of ST2 measured in a stable phase 4 months after STEMI were also associated with an increased risk of all-cause mortality (Figure). Figure 1 Conclusions High levels of ST2 in STEMI patients were associated with large infarct size, impaired recovery of LV function, and adverse clinical outcome in patients with STEMI. ST2 measured 4 months after STEMI remained associated with all-cause mortality.

Abstract Background In patients with Acute Myocardial Infarction (AMI) the levels of cardiac troponin T and absolute neutrophil count have been shown to correlate with infarct scar size and left ventricular ejection fraction (LVEF) as well as conferring a risk for major cardiovascular adverse events (MACE). In the context of myocardial infarction with non-obstructive coronary arteries (MINOCA) the prognostic role of such indicators has never been explored. Purpose To evaluate the prognostic role of known myocardial infarct size indicators in a MINOCA population compared to patients with obstructive AMI (Ob – AMI). Methods Among 1990 patients admitted to our coronary care unit from 2016 to 2019 with AMI, we enrolled 186 consecutive MINOCA patients according to the current ESC diagnostic criteria. We compared troponin peak levels, absolute neutrophil count at the time of hospital admission and LVEF in MINOCA patients versus Ob–AMI. Furthermore we assessed the prognostic value of these indicators. All-cause mortality and a composite end - point of all-cause mortality and myocardial re-infarction were evaluated. The median follow-up time was 19.6±12.9 months. Results MINOCA patients were more frequently females (64,9% vs 35,1%; p&lt;0.001), non-smokers (42,3% vs 61,8%; p&lt;0.001) with a lower prevalence of diabetes (9.9% vs 23.7%; p&lt;0.001) compared to the Ob-AMI population. Conversely, no differences were found in hypertension and dyslipidemia. As far as infarct size predictors are concerned, MINOCA patients showed lower levels of troponin value and absolute neutrophil count measured at the time of hospital admission (1838.27±601.0 ng/L vs 13543±3350.6 ng/L; p&lt;0.001, 6.7±1.36x109/L vs 7.1±1.29x109/L; p=0.001, respectively). Moreover, these patients exhibited a higher LVEF (56.1±10% vs 49.3±11%; p&lt;0.001) as compared to Ob-AMI. Among our MINOCA patients, 13 (10.6%) all-cause deaths and 3 (4.3%) myocardial re-infarction were observed during follow-up. Multivariable Cox-regression model demonstrated that mean troponin level, absolute neutrophil count and LVEF were not independent predictors of MACE (HR = 1.0, 95% CI: 0.9–1.1, p=0.6; HR = 0.96, 95% CI: 0.9–1.1, p=0.187; HR = 0.9, 95% CI: 0.79–1.02, p=0. 12 respectively). Conclusion MINOCA patients show a similar prognosis compared to the worldwide AMI population. However, in this study the outcome in the MINOCA population was not influenced by commonly used infarct size predictors, in contrast to what is observed in Ob-AMI patients. These results once again emphasize both the complexity of MINOCA patients and the importance of a better understanding of the different underlying pathophysiological mechanisms.
