Abstract Objective Dual antiplatelet therapy can reduce coronary thrombosis and improve the prognosis in patients with acute coronary syndrome (ACS). However, there was limited prognostic information about fibrinolytic dysregulation in patients with ACS. This study is aimed to evaluated the prevalence and impact of fibrinolytic dysregulation in patients with acute coronary syndrome (ACS). Methods We retrospectively analyzed coagulation and fibrinolysis related indexes of ACS in hospitalized adults with rapid thrombelastography between May 2016 and December 2018. All of the follow-up visits were ended by December 2019. The primary outcome was the occurrence of major adverse cardiovascular events (MACEs), which included unstable angina pectoris, non-fatal myocardial infarction, non-fatal cerebral infarction, heart failure and all-cause death. Results Three hundred thirty-eight patients were finally included with an average age of 62.5 ± 12.8 years old, 273 (80.5%) were males, 137(40.5%) patients were with ST-elevation myocardial infraction. Fibrinolysis shutdown (LY30<0.8%) and hyperfibrinolysis (LY30 >3.0%) were observed among 163 (48.2%) and 76(22.5%) patients, respectively. During a total of 603.2 person·years of follow-up period, 77 MACEs occurred (22.8%). Multivariate Cox regression analysis indicated that LY30 [HR: 1.101, 95% CI: 1.010–1.200, P = 0.028] was independently correlated with the occurrence of MACEs. The hazard ratios pertaining to MACEs in patients with fibrinolysis shutdown and hyperfibrinolysis compared with those in the physiologic range (LY30: 0.8–3.0%) were 1.196 [HR: 1.196, 95% CI: 0.679–2.109,P = 0.535] and 2.275 [HR: 2.275, 95% CI: 1.241–4.172, P = 0.003], respectively. Conclusions Fibrinolytic dysregulation is very common in selected patients with ACS, and hyperfibrinolysis (LY30 > 3%) is associated with poor outcomes in patients with ACS.

Abstract Background：Dual antiplatelet therapy can reduce coronary thrombosis and improve the prognosis in patients with acute coronary syndrome (ACS). However, there was limited prognostic information about fibrinolytic dysregulation in patients with ACS. This study is aimed to evaluated the prevalence and impact of fibrinolytic dysregulation in patients with acute coronary syndrome (ACS).Methods：We retrospectively analyzed coagulation and fibrinolysis related indexes of ACS in hospitalized adults with rapid thrombelastography between May 2016 and December 2018. All of the follow-up visits were ended by December 2019. The primary outcome was the occurrence of major adverse cardiovascular events (MACEs), which included unstable angina pectoris, non-fatal myocardial infarction, non-fatal cerebral infarction, heart failure and all-cause death. Results：338 patients were finally included with an average age of 62.5 ± 12.8 years old, 273 (80.5%) were males, 137(40.5%) patients were with STEMI. Fibrinolysis shutdown and hyperfibrinolysis were observed among 163 (48.2%) and 76(22.5%) patients, respectively. During a total of 603.2 person·years of follow-up period, 77 MACEs occurred (22.8%). Multivariate Cox regression analysis indicated that age [HR: 1.031 95% CI: 1.007-1.056, P = 0.012] and LY30 [HR: 1.097, 95% CI: 1.013-1.188, P = 0.023] were independently correlated with the occurrence of MACEs. The hazard ratios pertaining to MACEs in patients with LY30＜0.8% and ＞3.0% compared with those in the physiologic range(LY30: 0.8-3.0%) were 2.275 [HR: 2.275, 95% CI: 1.241-1.241, P = 0.003] and 1.196 [HR: 1.196, 95% CI: 0.679-2.109,P=0.535], respectively.Conclusions: Fibrinolytic dysregulation is very common in selected patients with ACS, and hyperfibrinolysis (HF) (LY30 >3%) is associated with poor outcomes in patients with ACS

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.

Abstract Background and aims: This study investigates the long-term prognostic value of homocysteine in patients with acute coronary syndrome complicated with hypertension. Methods:The current work is a multicenter, retrospective, observational cohort study. We consecutively enrolled 1288 ACS patients hospitalized in 11 general hospitals in Chengdu, China, from June 2015 to December 2019. The patients were divided into hypertension and non-hypertension groups, and each was further classified into hyperhomocysteinemia (H-Hcy) and normal homocysteinemia (N-Hcy) groups according to the cut-off value of homocysteine predicting long-term mortality during follow-up. In both groups, we used Kaplan-Meier and multivariate Cox regression analysis to assess the relationship between homocysteine and long-term prognosis. Results: The median follow-up time was 18 months (range: 13.83-22.37). During this period, 78 (6.05%) death cases were recorded. The hypertension was further divided into H-Hcy (n=245) and N-Hcy (n=543), with an optimal cut-off value of 16.81 µmol/L. Similarly, non-hypertension was further divided into H-Hcy (n=200) and N-Hcy (n=300), with an optimal cut-off value of 14 µmol/L. Kaplan-Meier survival curves revealed that H-Hcy had a significantly lower survival probability than N-Hcy, both in hypertension and non-hypertension (P-value<0.01). After adjusting for confounding factors, multivariate Cox regression analysis revealed that H-Hcy (HR=2.1923, 95% CI: 1.213-3.9625, P＜0.01) was an independent predictor of long-term all-cause death in ACS with hypertension, but not in non-hypertension.Conclusion: Elevated homocysteine level predicts risk of all-cause mortality in ACS with hypertension, but not in those without hypertension. it should be considered when determining risk stratification for ACS, particularly those complicating hypertension.

Introduction: Cardiopulmonary exercise testing (CPET) determines intensity for exercise rehabilitation which may improve outcomes in patients with acute coronary syndrome (ACS). However, it is unclear how many patients are given exercise education based on CPET around hospital discharge. Purposes: To assess the implementation of CPET and to evaluate the impacts of clinical parameters including CPET variables on 2-year outcomes in ACS patients. Methods: We enrolled 3146 ACS patients without hemodialysis (age, 68±12 yrs; 78% male) 30 days after onset using data from Mie ACS registry, a prospective and multicenter registry, between 2013 and 2017. We compared clinical characteristics in patients with and without CPET at hospital discharge. Prognostic factors including CPET variables during the 2-year follow-up were determined. Results: Forty percent of the hospitals had CPET equipment. Out of 3146, 431 patients (12%) underwent CPET and were given CPET-based exercise education. Implementation of CPET was associated with younger age, male, ST-elevation myocardial infraction, and higher peak creatine phosphokinase (p≤0.03). While, hospitalization length <7 days or >21 days was inversely associated with CPET. During the 2-year follow-up, 198 all-cause deaths (6%) and 103 heart failure (HF) hospitalization were observed. Multivariate Cox regression analysis demonstrated that age, male, hospitalization length >21 days, Killip ≥2, mechanical circulatory and/or ventilator support were positive predictors of all-cause death. While, CPET around hospital discharge (hazard ratio, 0.52; 95%CI, 0.27-0.99, p<0.05) and hemoglobin level were independent negative predictors of all-cause death. Although patients with CPET tended to have greater myocardial damage, they did not have increased rate of HF hospitalization or major adverse cardiovascular events (MACE). When analyzed only in patients with CPET, peak oxygen uptake was the only independent predictor for all-cause death. Conslusions: The number of patients who underwent CPET at discharge was small in our registry. Although the rate of HF hospitalization and MACE were similar in patients with and without CPET, CPET and CPET-based exercise education did reduce all-cause mortality in ACS patients.

AbstractBackgroundThe increase in soluble suppression of tumorigenicity 2 (sST2) both in the diagnosis and prognosis of heart failure is well established; however, existing data regarding sST2 values as the prognostic marker after myocardial infarction (MI) are limited and have been conflicting. This study aimed to assess the clinical significance of sST2 in predicting 1-year adverse cardiovascular (CV) events in MI patients.Materials and methodsIn this prospective study, 380 MI patients were included. Participants were grouped into low sST2 (n = 264, mean age: 60.0 ± 12.1 years) and high sST2 groups (n = 116, mean age: 60.5 ± 11.6 years), and all study populations were followed up for major adverse cardiovascular events (MACE) which are composed of CV mortality, target vessel revascularization (TVR), non-fatal reinfarction, stroke and heart failure.ResultsDuring a 12-month follow-up, 68 (17.8%) patients had MACE. CV mortality and heart failure were significantly higher in the high sST2 group compared to the low sST2 group (15.5% vs. 4.9%, p = 0.001 and 8.6% vs. 3.4% p = 0.032, respectively). Multivariate Cox regression analysis concluded that high serum sST2 independently predicted 1-year CV mortality [hazard ratio (HR) 2.263, 95% confidence interval (CI) 1.124–4.557, p = 0.022)]. Besides, older age, Killip class >1, left anterior descending (LAD) as the culprit artery and lower systolic blood pressure were the other independent risk factors for 1-year CV mortality.ConclusionsHigh sST2 levels are an important predictor of MACE, including CV mortality and heart failure in a 1-year follow-up period in MI patients.

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.

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.

Background. The present study aimed to evaluate the prevalence and prognosis of residual lipid abnormalities in statin-treated acute coronary syndrome (ACS) patients after percutaneous coronary intervention (PCI).Subjects and Methods. A total of 3,047 ACS patients who underwent PCI and received statin therapy were included. Plasma concentrations of LDL-C, HDL-C, and TG were measured. For the follow-up study, major adverse cardiovascular cerebrovascular events (MACCE; including total death, cardiovascular death, myocardial infarction, and revascularization) were documented.Results. A total of 93.14% of all individuals were followed up for 18.1 months (range, 0–29.3 months). Of all 3,047 patients, those with a suboptimal goal were 67.75%, 85.85%, and 33.64% for LDL-C, HDL-C, and TG levels, respectively. Multiple Cox regression analysis revealed there were significant increases in cumulative MACCE of 41% (HR = 1.41, 95% CI [1.09–1.82],p=0.008), and revascularization of 48% (HR = 1.48, 95% CI [1.10–1.99],p=0.01) in low HDL-C patients with ACS after PCI, but not the high TG group at the end of study.Conclusions. Our results showed there is high rate of dyslipidemia in Chinese ACS patients after PCI. Importantly, low HDL-C but not high TG levels are associated with higher MACCE and revascularization rates in ACS patients after PCI.

Abstract Funding Acknowledgements Type of funding sources: None. OnBehalf Netherlands Heart Registration Background It is important to gain more insight into cardiogenic shock (CS), as currently little is known on how to improve outcomes. The aim of this study was to assess the incidence, clinical outcome and predictors for mortality of CS in acute coronary syndrome (ACS) patients treated by percutaneous coronary intervention (PCI). Methods The Netherlands Heart Registration (NHR) is a nationwide registry on all cardiac interventions. We used NHR data of ACS patients treated with PCI between 2015 and 2019. CS was defined as shock present at admission. Cox regression analysis was used to calculate hazard ratios (HR) with 95% confidence intervals (CI). Results Among 75,407 ACS patients treated with PCI, 3,028 patients (4.1%) were identified with CS. The incidences of CS were respectively; 4.3%, 3.9%, 3.5% and 4.3% per year. Median follow-up duration was 9 months (IQR 0-26) for patients with CS and 22 months (IQR 12-36) for patients without CS. Thirty-day mortality was 36% for patient with CS and 3% for patients without CS (p &lt; 0.001). Factors independently associated with mortality in CS were: age (HR 1.02, 95%CI 1.02-1.03), estimated glomerular filtration rate (eGFR) (HR 0.98, 95%CI 0.98-0.99), diabetes mellitus (DM) (HR 1.25, 95%CI 1.08-1.45), multivessel disease (HR 1.22, 95%CI 1.06-1.39), prior myocardial infarction (MI) (HR 1.24, 95%CI 1.06-1.45) and out-of-hospital cardiac arrest (OHCA) (HR 1.71, 95%CI 1.50-1.94) (Table 1). Conclusion In this Dutch nationwide registry-based study of ACS patients treated by PCI, the incidence of CS was 4.1% over the 4-year study period. Predictors for mortality in CS were higher age, renal insufficiency, presence of DM, multivessel disease, prior MI and OHCA.

Abstract Background: Several studies found that baseline low LDL-C concentration was associated with poor prognosis in patients with acute coronary syndrome (ACS), which was called “cholesterol paradox”. Low LDL-C concentration may reflect underlying malnutrition, which was strongly associated with increased mortality. We objected to investigate the cholesterol paradox in patients with CAD and the effects of malnutrition.Method: A total of 41,229 CAD patients admitted to Guangdong Provincial People's Hospital in China were included in this study from January 2007 to December 2018, and divided into two groups (LDL-C < 1.8 mmol/L, n=4,863; LDL-C ≥ 1.8 mmol/L, n = 36,366). We used Kaplan-Meier method and Cox regression analyses to assess the association between LDL-C levels and long-term all-cause mortality and the effect of malnutrition. Result: In this real-world cohort (mean age 62.94 years; 74.94% male), there were 5257 incidents of all-cause death during a median follow-up of 5.20 years [Inter-quartile range (IQR): 3.05-7.78 years]. Kaplan–Meier analysis showed that low LDL-C levels were associated with worse prognosis. After adjusting for baseline confounders (e.g., age, sex and comorbidities, etc.), multivariate Cox regression analysis revealed that low LDL-C level (<1.8mmol/L) was not significantly associated with all-cause mortality (adjusted HR, 1.04; 95% CI, 0.96-1.24). After adjustment of nutritional status, risk of all-cause mortality of patients with low LDL-C level decreased (adjusted HR, 0.90; 95% CI, 0.83-0.98). In the final multivariate Cox model, low LDL-C level was related to better prognosis (adjusted HR, 0.91; 95% CI, 0.84-0.99).Conclusion: Our results demonstrate that the cholesterol paradox persisted in CAD patients, but disappeared after accounting for the effects of malnutrition.
