Progression of atrial fibrillation (AF) is associated with worsened prognosis for cardiovascular events and mortality. Exercise-based-cardiac rehabilitation programmes have shown preliminary promise for primary and secondary prevention of AF. Yet, such interventions are typically reserved for patients with acute coronary syndrome or undergoing revascularization. Using a retrospective cohort design, the present study investigated the association of exercise-based cardiac rehabilitation on the progression of paroxysmal to sustained AF, compared to propensity-matched controls. Patients with a diagnosis of paroxysmal AF were compared between those with and without an electronic medical record of exercise-based cardiac rehabilitation within 6-months of diagnosis. Using cox regression models, we ascertained odds of 2-year incidence for AF progression. This cohort of 9808 patients with paroxysmal AF demonstrated that exercise-based cardiac rehabilitation was associated with 26% lower odds of AF progression (odds ratio 0.74, 95% CI 0.66–0.83) compared to propensity-matched controls. This beneficial effect seemed to vary across patient subgroups. In conclusion, findings revealed that exercise-based cardiac rehabilitation was associated with significantly lower odds of progression from paroxysmal to sustained AF at 2-years follow-up compared to propensity-matched controls.

Abstract Background Efforts to predict incident atrial fibrillation (AF) may be associated with complications, and there is interest in AF prediction in primary prevention (PP; pts with risk factors) and secondary prevention (SP; pts with possible AF complications). These pts have different risk levels, we sought whether that influenced the predictive value of LV dysfunction (measured as global longitudinal strain, GLS) or LA dysfunction (LA reservoir strain). Methods The PP cohort comprised 351 community-based pts ≥65 years with ≥1 risk factor for AF (age 70±4y,43% male, median follow-up 22 months) and the SP cohort comprised 532 pts after transient ischaemic attack or stroke (age 68±12y, 51% male, median follow-up 36 months). GLS and LA strain were measured offline (Image Arena-Tomtec, Germany). AF was diagnosed by 12 lead ECG, Holter or by single lead monitor. The clinical and echocardiographic characteristics of those with AF were compared to those in sinus rhythm. Nested Cox-regression models were used to assess for independent and incremental predictive value of LA strain/GLS in both cohorts. Results Compared to SP, PP had higher clinical AF risk (CHARGE-AF 5.6±5.5% vs 4.7±12.1%, p=0.02) but a lower thromboembolic risk (CHA2DS2-VASC 3±2 vs. 4±2, p<0.001). AF developed in 42 PP pts (12%) and 61 SP (12%). AF patients were older, with higher CHARGE-AF score, LA volume and LV mass. Pts developing AF had reduced GLS (17±4% vs. 20±3%, p<0.001), reservoir (28±11% vs. 35±8%, p<0.001) and pump strain (13±7% vs. 17±5%, p<0.001). GLS and LA strain had greater AUC in SP (0.84 vs 0.58 for GLS and 0.85 vs 0.57 for reservoir strain, both p<0.001). Nested cox-regression models showed that LA reservoir strain was independently associated with AF in both cohorts (p<0.05). GLS was only independently associated with incident AF in SP (Figure). Conclusion LA reservoir strain is independently associated with AF in different risk cohorts and its effect is incremental to clinical parameters and LA volume. GLS may be more useful in AF risk assessment in those in SP. Acknowledgement/Funding This study was partially supported by the Tasmanian Community Fund and Siemens Healthcare Australia.

Abstract Introduction Heart failure (HF) is a well-known risk factor for atrial fibrillation (AF). Moreover, HF is associated with worse clinical outcomes in patients with known AF. Recently, phenotypes of HF have been redefined according to the level of ejection fraction (EF). New data are needed to understand if a differential risk for outcomes exists according to the new phenotypes' definitions. Purpose To evaluate the risk of major adverse outcomes in patients with AF and HF according to HF clinical phenotypes. Methods We performed a subgroup analysis of AF patients enrolled in the EORP-AF Long-Term General Registry with a history of HF at baseline, available EF and follow-up data. Patients were categorized as follows: i) EF<40%, i.e. HF reduced EF [HFrEF]; ii) EF 40–49%, i.e. HF mid-range EF [HFmrEF]; iii) EF ≥50%, i.e. HF preserved EF [HFpEF]. Any thromboembolic event (TE)/acute coronary syndrome (ACS)/cardiovascular (CV) death, CV death and all-cause death were recorded. Results A total of 3409 patients were included in this analysis: of these, 907 (26.6%) had HFrEF, 779 (22.9%) had HFmrEF and 1723 (50.5%) had HFpEF. An increasing proportion with CHA2DS2-VASc ≥2 was found across the three groups: 90.4% in HFrEF, 94.6% in HFmrEF and 97.3% in HFpEF (p<0.001), while lower proportions of HAS-BLED ≥3 were seen (28.0% in HFrEF, 26.3% in HFmrEF and 23.6% in HFpEF, p=0.035). At discharge patients with HFpEF were less likely treated with antiplatelet drugs (22.0%) compared to other classes and were less prescribed with vitamin K antagonists (VKA) (57.0%) and with any oral anticoagulant (OAC) (85.7%). No differences were found in terms of non-vitamin K antagonist oral anticoagulant use. At 1-year follow-up, a progressively lower rate for all study outcomes (all p<0.001), with an increasing cumulative survival, was found across the three groups, with patients with HFpEF having better survival (all p<0.0001 for Kaplan-Meier curves). After full adjustment, Cox regression analysis showed that compared to HFrEF, HFmrEF and HFpEF were associated with risk of all study outcomes (Table). Cox Regression Analysis HR (95% CI) Any TE/ACS/CV Death CV Death All-Cause Death HFmrEF 0.65 (0.49–0.86) 0.53 (0.38–0.74) 0.55 (0.41–0.74) HFpEF 0.50 (0.39–0.64) 0.42 (0.31–0.56) 0.45 (0.35–0.59) ACS = Acute Coronary Syndrome; CI = Confidence Interval; CV = Cardiovascular; EF = Ejection Fraction; HF = Heart Failure; HR = Hazard Ratio. Conclusions In this cohort of AF patients with HF, HFpEF was the most common phenotype, being associated with a profile related to an increased thromboembolic risk. Compared to HFrEF, both HFmrEF and HFpEF were associated with a lower risk of all major adverse outcomes in AF patients.

Aims In recent years, stroke prevention in patients with atrial fibrillation (AF) has radically changed, with increasing use of non-vitamin K antagonist oral anticoagulants (NOACs). Contemporary European data on AF thromboprophylaxis are needed. Methods and results We report 1-year follow-up data from the EURObservational Research Programme in Atrial Fibrillation (EORP-AF) General Long-Term Registry. Outcomes were assessed according to antithrombotic therapy. At 1-year follow-up, 9663 (88.0%) patients had available data for analysis: 586 (6.1%) were not treated with any antithrombotic; 681 (7.0%) with antiplatelets only; 4066 (42.1%) with vitamin K antagonist (VKA) only; 3167 (32.8%) with NOACs only; and 1163 (12.0%) with antiplatelet and oral anticoagulant. At 1-year follow-up, there was a low rate of stroke (0.7%) and any thromboembolic event (TE) (1.2%), while haemorrhagic events occurred in 222 patients (2.3%). Cardiovascular (CV) death and all-cause death occurred in 3.9% and 5.2% of patients, respectively. Cumulative survival for all the three main outcomes considered was highest amongst patients treated only with NOACs (P &lt; 0.0001). Multivariable-adjusted Cox regression analysis found that VKA or NOACs use was independently associated with a lower risk for any TE/acute coronary syndrome/CV death, while all treatments were independently associated with a lower risk for CV death and all-cause death. Conclusion The 1-year follow-up of EORP-AF General Long-Term Registry reported a low occurrence of thromboembolic and haemorrhagic events, although mortality was high. Both VKA and NOACs were associated with a lower risk of all main adverse outcomes. All treatments were associated with a lower risk for CV death and all-cause death.

Plaque Erosion

Abstract Background Plaque erosion (PE) is responsible for at least one-third of acute coronary syndrome (ACS). Inflammatory activation is considered a key mechanism of plaque instability in patients with plaque rupture through the release of metalloproteinases and the inhibition of collagen synthesis that in turns lead to fibrous cap degradation. However, the clinical relevance of macrophage infiltration has never been investigated in patients with PE. Purpose In our study, we aimed at assessing the presence of optical coherence tomography (OCT)-defined macrophage infiltrates (MØI) at the culprit site in ACS patients with PE, evaluating their clinical and OCT correlates, along with their prognostic value. Methods ACS patients undergoing OCT imaging and presenting PE as culprit lesion were retrospectively selected. Presence of MØI at culprit site and in non-culprit segments along the culprit vessel was assessed. The incidence of major adverse cardiac events (MACEs), defined as the composite of cardiac death, recurrent myocardial infarction and target vessel revascularization (TVR), was assessed [follow-up median (interquartile range, IQR) time 2.5 (2.03–2.58) years]. Results We included 153 patients [median age (IQR) 64 (53–75) years, 99 (64.7%) males]. Fifty-one (33.3%) patients presented PE with MØI and 102 (66.7%) PE without MØI. Patients having PE with MØI compared with PE patients without MØI had more vulnerable plaque features both at culprit site and at non-culprit segments. In particular, culprit lesion analysis demonstrated that patients with PE with MØI had a significantly thinner fibrous cap [median (IQR) 100 (60–120) μm vs. 160 (95–190) μm, p&lt;0.001], higher prevalence of thrombus [41 (80.4%) vs. 64 (62.7%), p=0.028], lipid plaque [39 (76.5%) vs. 50 (49.0%), p&lt;0.001], TCFA [20 (39.2%) vs. 14 (13.7%), p=0.001], and a higher maximum lipid arc [median [IQR] 250.0° (177.5°-290.0°) vs. 190.0° (150.0°-260.0°), p=0.018) at the culprit lesion compared with PE without MØI. MACEs were significantly more frequent in PE with MØI patients compared with PE without MØI [11 (21.6%) vs. 6 (5.9%), p=0.008], mainly driven by a higher risk of cardiac death and TVR. At multivariable Cox regression model, PE with MØI [HR=2.95, 95% CI (1.09–8.02), p=0.034] was an independent predictor of MACEs. Conclusion Our study demonstrates that among ACS patients with PE the presence of MØI at culprit lesion is associated with a more aggressive phenotype of coronary atherosclerosis with more vulnerable plaque features, along with a worse prognosis at a long-term follow-up. These findings are of the utmost importance in the era of precision medicine because clearly show that macrophage infiltrates may identify patients with a higher cardiovascular risk requiring more aggressive secondary prevention therapies and a closer clinical follow-up.

Abstract Background Cardiovascular disease is the leading cause of disease burden globally. With advancements in medical and surgical care more people are surviving initial acute coronary syndrome (ACS) and are in need of secondary prevention and cardiac rehabilitation (CR). Increasing availability of high quality individual-level data linkage provides robust estimates of outcomes long-term. Purpose To compare 3 year outcomes amongst ACS survivors who did and did not participate in Australian CR programs. Methods SNAPSHOT ACS follow-up study included 1806 patients admitted to 232 hospitals who were followed-up by data linkage (cross-jurisdictional morbidity, national death index, Pharmaceutical Benefit Schedule) at 6 and 36 months to compare those who did/not attend CR. Results In total, the cohort had a mean age of 65.8 (13.4) years, 60% were male, only 25% (461/1806) attended CR. During index admission, attendees were more likely to have had PCI (39% v 14%, p&lt;0.001), CABG (11% v 2%, p&lt;0.001) and a diagnosis of STEMI (21% v 5%, p&lt;0.001) than those who did not attend. However, there was no significant difference between CR attendees/non-attendees for risk factors (LDL-cholesterol, smoking, obesity). Only 19% of eligible women attended CR compared to 30% of men (p&lt;0.001). At 36 months, there were fewer deaths amongst CR attendees (19/461, 4.1%) than non-attendees (116/1345, 8.6%) (p=0.001). CR attendees were more likely to have repeat ACS, PCI, CABG at both 6 and 36 months (Table). At 36 months, CR attendees were more likely to have been prescribed antiplatelets (78% v 53%, p&lt;0.001), statins (91% 73%, p&lt;0.001), beta-blockers (11% v 13%, p=0.002) and ACEI/ARBs (72% v 61%, p&lt;0.001) than non-attendees. Conclusions Amongst Australian ACS survivors, participation in CR was associated with less likelihood of death and increased prescription of pharmacotherapy. However, attendance at CR was associated with higher rates of repeat ACS and revascularisation. Funding Acknowledgement Type of funding source: Foundation.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction There is some evidence suggesting that exaggerated hypertensive response to exercise (HRE) may be associated with higher risk of future cardiovascular events, however the relationship between systolic blood pressure (SPB) during exercise test and stroke is not fully understood. Purpose To evaluate the ability to predict the risk of stroke in patients with HRE in exercise test. Methods Single-center retrospective study of consecutive patients submitted to exercise test from 2012 to 2015 with HRE to stress test. HRE was defined as a peak systolic blood pressure (PSBP) &gt; 210 mmHg in men and &gt; 190 mmHg in women, or a rise of the SBP of 60 mmHg in men or 50 mmHg in women or as a diastolic blood pressure &gt; 90 mmHg or a rise of 10 mmHg. Patient’s demographics, baseline clinical characteristics, vital signs during the stress test and the occurrence of stroke during follow-up were analysed Results We included 458 patients with HRE (76% men, 57.5 ± 10.83 years). The most frequent comorbidities were hypertension (83%), dyslipidaemia (61%), previously known coronary disease (32%), diabetes (28%) and smoking (38%). Atrial fibrillation was present in 5.9% of patients. During a mean follow-up of 60 ± 2 months, the incidence of stroke was 2.1% (n = 8), all with ischemic origin. Considering the parameters analysed on exercise test, only PSBP demonstrated to be an independent predictor of stroke (HR 1.042, CI95% 1.002-1.084, p = 0.039,) with moderate ability to predict stroke (AUC 0.735, p = 0.0016) with a most discriminatory value of 203 mmHg (sensibility 56%, specify 67%). Regarding baseline characteristics, after age, sex and comorbidities adjustment, previously controlled hypertension was found to be an independent protective factor of stroke (OR 4.247, CI 95% 0.05-0.9, p = 0.036) and atrial fibrillation was an independent predictor of stroke occurrence (HR 8.1, CI95% 1.4-46.9, p = 0.018). Atrial fibrillation was also associated with hospitalization of cardiovascular cause and major cardiovascular events occurrence (mortality, coronary syndrome and stroke). Baseline SBP was associated with atrial fibrillation development (p = 0.008). Conclusion According to our results, PSBP during exercise test is an independent predictor of stroke occurrence and should be considered as a potencial additional tool to predict stroke occurrence, particularly in high risk patients. The identification of diagnosed hypertension as a protective factor of stroke may be explained by the cardioprotective effect of antihypertensive drugs.

Background: Whether the association of chronic kidney disease (CKD) with cardiovascular risk differs based on diabetes mellitus (DM) and hypertension (HTN) status remains unanswered. Methods: We investigated 11,050 participants from the Atherosclerosis Risk in Communities Study (fourth examination (1996-1998)) with follow-up for cardiovascular outcomes (coronary disease, heart failure and stroke) through 2009. Using the Cox regression models, we quantified cardiovascular risk associated with estimated glomerular filtration rate (eGFR) and urinary albumin-to-creatinine ratio (ACR) in individuals with and without DM and/or HTN and assessed their interactions. Results: Individuals with DM and HTN generally had higher cardiovascular risk relative to those without at all the levels of eGFR and ACR. Cardiovascular risk increased with lower eGFR and higher ACR regardless of DM and HTN status (e.g. adjusted hazards ratio (HR) for eGFR 30-44 vs. 90-104 ml/min/1.73 m2, 2.32 (95% CI, 1.66-3.26) in non-diabetics vs. 1.83 (1.25-2.67) in diabetics and 2.45 (2.20-5.01) in non-hypertensives vs. 1.51 (1.27-1.81) in hypertensives and corresponding adjusted HR for ACR 30-299 vs. <10 mg/g, 1.70 (1.45-2.00) vs. 1.34 (1.10-1.64) and 1.42 (1.10-1.85) vs. 1.57 (1.36-1.81), respectively). Only the ACR-DM interaction reached significance, with a shallower relative risk gradient among diabetics than among non-diabetics (p = 0.02). Analysis of individual cardiovascular outcomes showed similar results. Conclusion: Although individuals with DM and HTN generally had higher cardiovascular risk relative to those without these complications, both low eGFR and high ACR were associated with cardiovascular diseases regardless of the presence or absence of DM and HTN. These findings reinforce the importance of CKD in cardiovascular outcomes.

Abstract Background High plasma B-Type natriuretic peptide (BNP) level is associated with cardiac events or stroke in patients with atrial fibrillation (AF). However, it is still unknown whether BNP predicts worse clinical outcomes after catheter ablation ofAF. Purpose We aimed to see if plasma BNP level is associated with major adverse cardiac and cerebrovascular events (MACCE) after catheter ablation of AF. Methods We retrospectively analyzed 1,853 participants (73.1% men, mean age 63.3±10.3 years, 60.7% paroxysmal AF) who received first catheter ablation of AF with pre-ablation plasma BNP level measurement and completed follow-up more than 3 months after the procedure from AF Frontier Ablation Registry, a multicenter cohort study in Japan. We evaluated an association between plasma BNP level before catheter ablation and first MACCE in cox-regression hazard models adjusted for known risk factors. MACCE were defined as stroke/transient ischemic attack (TIA), cardiovascular events or all-cause death. Results The mean plasma BNP level was 120.2±3.7 pg/mL. During a mean follow-up period of 21.9 months, 57 patients (3.1%) suffered MACCE (ischemic stroke 8 [14.0%], hemorrhagic stroke 5 [8.8%], TIA 5 [8.8%], hospitalization for heart failure 11 [19.2%], acute coronary syndrome 9 [15.8%], hospitalization for other cardiovascular events 8 [14.0%] and all-cause death 11 [19.2%]). Plasma BNP level of patients with MACCE were significantly higher than those without MACCE (291.7±47.0 vs 114.7±3.42 pg/mL, P&lt;0.001). Multivariate analysis revealed that plasma BNP level (hazard ratio [HR] per 10 pg/mL increase 1.014; 95% confidence interval [CI] 1.005–1.023; P=0.001), baseline age (HR 1.052; 95% CI 1.022–1.084; P=0.001), heart failure (HR 2.698; 95% CI 1.512–4.815; P=0.001), old myocardial infarction (HR 3.593; 95% CI 1.675–7.708; P=0.001) and non-ischemic cardiomyopathy (HR 2.676; 95% CI 1.337 - 5.355; P=0.005) were independently associated with MACCE. At receiver-operating characteristic curve analysis, plasma BNP level before catheter ablation ≥162.7 pg/mL was the best threshold to predict MACCE (area under the curve: 0.71). Kaplan-Meier curve analysis (Figure) showed that the cumulative incidence of MACCE was significantly higher in patients with a BNP ≥162.7 pg/mL than in those with a BNP below 162.7 pg/mL (HR 4.85; 95% CI 2.86–8.21; P&lt;0.001). Conclusions Elevation of plasma BNP level was independently related to the increased risk of MACCE after catheter ablation ofAF. Funding Acknowledgement Type of funding source: Private company.

Cardiac Troponins

Abstract Aims Cardiac troponins (cTn) have been reported to be predictors for adverse outcomes in atrial fibrillation (AF), patients, but their actual use is still unclear. To assess the factors associated with cTn testing in routine clinical practice and to evaluate the association of elevated levels of cTn with adverse outcomes in a large contemporary cohort of European AF patients. Methods and results Patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry were stratified into three groups according to cTn levels as (i) cTn not tested, (ii) cTn in range (≤99th percentile), and (iii) cTn elevated (&gt;99th percentile). The composite outcome of any thromboembolism/any acute coronary syndrome (ACS)/cardiovascular (CV) death, defined as major adverse cardiovascular events (MACE) and all-cause death were the main endpoints. 10 445 (94.1%) AF patients were included in this analysis [median age 71 years, interquartile range (IQR): 63–77; males 59.7%]. cTn were tested in 2834 (27.1%). Overall, cTn was elevated in 904 (8.7%) and in-range in 1930 (18.5%) patients. Patients in whom cTn was tested tended to be younger (P &lt; 0.001) and more frequently presenting with first detected AF and atypical AF-related symptoms (i.e. chest pain, dyspnoea, or syncope) (P &lt; 0.001). On multivariable logistic regression analysis, female sex, in-hospital enrollment, first-detected AF, CV risk factors, history of coronary artery disease (CAD), and atypical AF symptoms were independently associated with cTn testing. After a median follow-up of 730 days (IQR: 692–749), 957 (9.7%) composite endpoints occurred while all-cause death was 9.5%. Kaplan–Meier analysis showed a higher cumulative risk for both outcomes in patients with elevated cTn levels (Figure) (Log Rank tests, P &lt; 0.001). On adjusted Cox regression analysis, elevated levels of cTn were independently associated with a higher risk for MACE [hazard ratio (HR): 1.74, 95% confidence interval (CI): 1.40–2.16] and all-cause death (HR 1.45, 95% CI: 1.21–1.74). Elevated levels of cTn were independently associated with a higher occurrence of MACE, all-cause death, any ACS, CV death and hospital readmission even after the exclusion of patients with history of CAD, diagnosis of ACS at discharge, those who underwent coronary revascularization during the admission and/or who were treated with oral anticoagulants plus antiplatelet therapy. Conclusions Elevated cTn levels were independently associated with an increased risk of all-cause mortality and adverse CV events, even after exclusion of CAD patients. Clinical factors that might enhance the need to rule out CAD were associated with cTn testing.

Aims: The present study aimed to investigate the prognostic role of derived neutrophil-to-lymphocyte ratio (dNLR) in patients with coronary heart disease (CHD) after PCI.Methods: A total of 3,561 post-PCI patients with CHD were retrospectively enrolled in the CORFCHD-ZZ study from January 2013 to December 2017. The patients (3,462) were divided into three groups according to dNLR tertiles: the first tertile (dNLR &lt; 1.36; n = 1,139), second tertile (1.36 ≥ dNLR &lt; 1.96; n = 1,166), and third tertile(dNLR ≥ 1.96; n = 1,157). The mean follow-up time was 37.59 ± 22.24 months. The primary endpoint was defined as mortality (including all-cause death and cardiac death), and the secondary endpoint was major adverse cardiovascular events (MACEs) and major adverse cardiovascular and cerebrovascular events (MACCEs).Results: There were 2,644 patients with acute coronary syndrome (ACS) and 838 patients with chronic coronary syndrome (CCS) in the present study. In the total population, the all-cause mortality (ACM) and cardiac mortality (CM) incidence was significantly higher in the third tertile than in the first tertile [hazard risk (HR) = 1.8 (95% CI: 1.2–2.8), p = 0.006 and HR = 2.1 (95% CI: 1.23–3.8), p = 0.009, respectively]. Multivariate Cox regression analyses suggested that compared with the patients in the first tertile than those in the third tertile, the risk of ACM was increased 1.763 times (HR = 1.763, 95% CI: 1.133–2.743, p = 0.012), and the risk of CM was increased 1.763 times (HR = 1.961, 95% CI: 1.083–3.550, p = 0.026) in the higher dNLR group during the long-term follow-up. In both ACS patients and CCS patients, there were significant differences among the three groups in the incidence of ACM in univariate analysis. We also found that the incidence of CM was significantly different among the three groups in CCS patients in both univariate analysis (HR = 3.541, 95% CI: 1.154–10.863, p = 0.027) and multivariate analysis (HR = 3.136, 95% CI: 1.015–9.690, p = 0.047).Conclusion: The present study suggested that dNLR is an independent and novel predictor of mortality in CHD patients who underwent PCI.
