Plasma DPP4 activity is associated with no-reflow and major bleeding events in Chinese PCI-treated STEMI patients.

ABSTRACT: Dipeptidyl peptidase-4 (DPP4) is an important regulator of incretins and inflammation, and it is involved in the pathophysiological process of myocardial infarction (MI). This study investigated the role of plasma DPP4 activity (DPP4a) in patients with ST-segment elevation myocardial infarction (STEMI) who had undergone percutaneous coronary intervention (PCI). We recruited 747 consecutive PCI-treated STEMI patients from a tertiary referral center from January 2014 to October 2015. The outcomes of interest were the rates of no-reflow, in-hospital major adverse cardiac or cerebrovascular events (iMACCE), in-hospital complications (IHC) and in-hospital major bleeding. The DPP4a was lower in STEMI patients compared with the controls (p?

Access-Site vs Non-Access-Site Major Bleeding and In-Hospital Outcomes Among STEMI Patients Receiving Primary PCI.

Project description:BackgroundMajor bleeding (MB) is an independent predictor of mortality among ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (pPCI). Prevention of access-site MB has received significant attention. However, limited data have been obtained on the influence of access-site MB vs non-access-site MB and association with subsequent adverse in-hospital outcomes in the STEMI population undergoing pPCI.MethodsWe identified 1494 STEMI patients who underwent pPCI between 2012 and 2018. Unadjusted and adjusted differences among patients with no MB, access-site MB, non-access-site MB, and in-hospital clinical outcomes were assessed. The use of bleeding-avoidance strategies and their effects on MB were also evaluated.ResultsMB occurred in 121 (8.1%) patients. Access-site MB occurred in 34 (2.3%) patients, and non-access-site MB occurred in 87 (5.8%). The median reduction in hemoglobin was 31 g/L (interquartile range: 19-43) with access-site MB, and 44 g/L (interquartile range: 29-62) with non-access-site MB. After multivariable adjustment, non-access-site MB was independently associated with in-hospital death (adjusted odds ratio [aOR] 4.21; 95% confidence interval [CI] 2.04-8.68), cardiogenic shock (aOR 10.91; 95% CI 5.67-20.98), and cardiac arrest (aOR 5.63; 95% CI 2.88-11.01). Conversely, access-site MB was not associated with adverse in-hospital outcomes. Bleeding-avoidance strategies were used frequently; however, after multivariable adjustment, no single bleeding-avoidance strategy was significantly associated with reduced MB.ConclusionsIn STEMI patients undergoing pPCI, non-access-site MB was independently associated with adverse in-hospital outcomes, whereas access-site MB was not. Additional study of strategies to reduce the incidence and impact of non-access-site MB appears to be warranted.

Relationships between circulating branched chain amino acid concentrations and risk of adverse cardiovascular events in patients with STEMI treated with PCI.

Project description:The incidence of in-hospital cardiovascular adverse events (AEs) in patients with ST-segment elevation myocardial infarction (STEMI) following primary percutaneous coronary intervention (PCI) is relatively high. Identification of metabolic markers could improve our understanding of the underlying pathological changes in these patients. We aimed to identify associations between concentrations of plasma metabolites on admission and development of in-hospital AEs in post-PCI patients with STEMI. We used targeted mass spectrometry to measure plasma concentrations of 26 amino acid metabolites on admission in 96 patients with STEMI who subsequently developed post-PCI AEs and in 96 age- and sex-matched patients without post-PCI cardiovascular AEs. Principal component analysis (PCA) revealed that PCA-derived factors, including branched chain amino acids (BCAAs), were associated with increased risks of all three pre-specified outcomes: cardiovascular mortality/acute heart failure (AHF), cardiovascular mortality, and AHF. Addition of BCAA to the Global Registry of Acute Coronary Events risk score increased the concordance C statistic from 0.702 to 0.814 (p?<?0.001), and had a net reclassification index of 0.729 (95% confidence interval, 0.466-0.992, p?<?0.001). These findings demonstrate that high circulating BCAA concentrations on admission are associated with subsequent in-hospital AEs after revascularization in patients with STEMI.

Impact of periprocedural morphine use on mortality in STEMI patients treated with primary PCI.

Project description:BackgroundIntravenous morphine (MO) decreases the effect of all oral platelet P2Y12 receptor inhibitors in vitro and observational reports suggest that its use may be associated with larger infarct size. Yet, there are limited data available about the impact of this interaction on clinical outcomes. We studied the effect of MO on mortality in ST-segment elevation myocardial infarction (STEMI) patients treated with primary PCI using a prospective registry.MethodsOf the 1255 patients who underwent primary PCI, 397 received MO based on physician's judgment. Clopidogrel was used as P2Y12 receptor antagonist in all cases. Median follow-up time was 7.5 years with 457 deaths. To adjust for confounding, two propensity score-based procedures were performed: 1 to 1 matching (PSM, 728 cases), and inverse probability of treatment weighting (IPTW) retaining data from all patients. Primary outcome measure was time to all-cause death, whereas predischarge left ventricular ejection fraction (LVEF) was used as secondary end point.ResultsAn adequate balance on baseline covariates was achieved by both methods. We found no difference in survival as the HR (MO/no MO) was 0.98 (95% confidence interval [CI]: 0.76-1.26), p = 0.86 using PSM and 1.01 (95% CI: 0.84-1.23), p = 0.88 with IPTW. Likewise, distributions of LVEFs were similar using either methods: with PSM, median LVEFs were 50.0% (interquartile range [IQR]: 43.0%-55.3%) vs 50.0% (IQR: 42.0%-55.0%) in the no MO and MO groups, respectively (p = 0.76), whereas using IPTW, they were 50.0% (IQR: 42.5%-55.0%) vs 50.0% (IQR: 41.0%-55.0%), respectively (p = 0.86).ConclusionsOur data suggest that morphine use may have no impact on long-term mortality and on predischarge ejection fraction in STEMI patients treated with primary PCI.

Concurrent use of Chinese herbal medicine and anticoagulants may reduce major bleeding events.

Project description:BackgroundThis retrospective cohort study investigated the risk of major bleeding events during the concurrent use of Chinese herbal medicine (CHM) and anticoagulants in clinical practice.MethodsA total of 4,470 patients receiving anticoagulant drugs were selected from Taiwan's National Health Insurance Research Database (NHIRD). Half (n = 2,235) were also using CHMs (CHM cohort); the other half were not (non-CHM cohort). Each cohort was matched 1:1 using the propensity score. Chi-square testing and the Student's t-test were used to examine differences between two cohorts. Cox proportional hazard regression analysis assessed the risks for major bleeding events in each cohort, as well as bleeding risks associated with specific CHM formulas and herbs. Cumulative incidence curves for major bleeding events were calculated using Kaplan-Meier analysis.ResultsCompared with the non-CHM cohort, the CHM cohort had a lower risk of overall bleeding events (p < 0.001) including hemorrhagic stroke (p = 0.008), gastrointestinal (GI) bleeding (p < 0.001), urogenital bleeding (p ≤ 0.001) and nasal/ear/eye bleeding (p = 0.004). Single herbs, such as Glycyrrhiza uralensis et Rhizoma, Panax notoginseng, Panax ginseng, Platycodon grandiflorum, Eucommia ulmoides Oliver and formulas, such as Shu Jing Huo Xue Tang, Shao Yao Gan Cao Tang and Ji Sheng Shen Qi Wan were associated with a lower risk of major bleeding events.ConclusionUsing CHMs with anticoagulants appeared to decrease the risk of major bleeding, especially CHMs products containing Glycyrrhiza uralensis et Rhizoma, Panax notoginseng, Panax ginseng, Platycodon grandiflorum and Eucommia ulmoides Oliver. Further investigations are needed to determine whether CHM can maintain the therapeutic efficacy of anticoagulants while simultaneously reducing potential side effects.

Prognostic implications and outcomes of cardiac arrest among contemporary patients with STEMI treated with PCI.

Project description:BackgroundCardiac arrest (CA) complicating ST-elevation myocardial infarction (STEMI) is associated with a disproportionately higher risk of mortality. We described the contemporary presentation, management, and outcomes of CA patients in the era of primary percutaneous coronary intervention (PCI).MethodsWe reviewed 1,272 consecutive STEMI patients who underwent PCI between 1/1/2011-12/31/2016 and compared characteristics and outcomes between non-CA (N = 1,124) and CA patients (N = 148), defined per NCDR definitions as pulseless arrest requiring cardiopulmonary resuscitation and/or defibrillation within 24-hr of PCI.ResultsMale gender, cerebrovascular disease, chronic kidney disease, in-hospital STEMI, left main or left anterior descending culprit vessel, and initial TIMI 0 or 1 flow were independent predictors for CA. CA patients had longer door-to-balloon-time (106 [83,139] vs. 97 [74,121] minutes, p = 0.003) and greater incidence of cardiogenic shock (48.0% vs. 5.9%, p < 0.001), major bleeding (25.0% vs. 9.4%, p < 0.001), and 30-day mortality (16.2% vs. 4.1%, p < 0.001). Risk score for 30-day mortality based on presenting characteristics provided excellent prognostic accuracy (area under the curve = 0.902). However, over long-term follow-up of 4.5 ± 2.4 years among hospital survivors, CA did not portend any additional mortality risk (HR: 1.01, 95% CI: 0.56-1.82, p = 0.97).ConclusionsIn a contemporary cohort of STEMI patients undergoing primary PCI, CA occurs in >10% of patients and is an important mechanism of mortality in patients with in-hospital STEMI. While CA is associated with adverse outcomes, it carries no additional risk of long-term mortality among survivors highlighting the need for strategies to improve the in-hospital care of STEMI patients with CA.

The abnormal level and prognostic potency of multiple inflammatory cytokines in PCI-treated STEMI patients.

Project description:ObjectiveInflammatory cytokines modulate atherogenesis and plaque rupture to involve in ST-segment elevation myocardial infarction (STEMI) progression. The present study determined eight inflammatory cytokine levels in 212 percutaneous coronary intervention (PCI)-treated STEMI patients, aiming to comprehensively investigate their potency in estimating major adverse cardiac event (MACE) risk.MethodsSerum tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, IL-8, IL-10, IL-17A, vascular cell adhesion molecule-1 (VCAM-1), and intercellular adhesion molecule-1 (ICAM-1) of 212 PCI-treated STEMI patients and 30 angina pectoris patients were determined using enzyme-linked immunosorbent assay.ResultsTNF-α (52.5 (43.9-62.6) pg/ml versus 46.4 (39.0-59.1) pg/ml, p = 0.031), IL-8 (61.6 (49.6-81.7) pg/ml versus 46.7 (32.5-63.1) pg/ml, p = 0.001), IL-17A (57.4 (45.7-77.3) pg/ml versus 43.2 (34.2-64.6) pg/ml, p = 0.001), and VCAM-1 (593.6 (503.4-811.4) ng/ml versus 493.8 (390.3-653.7) ng/ml, p = 0.004) levels were elevated in STEMI patients compared to angina pectoris patients, while IL-1β (p = 0.069), IL-6 (p = 0.110), IL-10 (p = 0.052), and ICAM-1 (p = 0.069) were of no difference. Moreover, both IL-17A high (vs. low) (p = 0.026) and VCAM-1 high (vs. low) (p = 0.012) were linked with increased cumulative MACE rate. The multivariable Cox's analysis exhibited that IL-17A high (vs. low) (p = 0.034) and VCAM-1 high (vs. low) (p = 0.014) were independently associated with increased cumulative MACE risk. Additionally, age, diabetes mellitus, C-reactive protein, multivessel disease, stent length, and stent type were also independent factors for cumulative MACE risk.ConclusionIL-17A and VCAM-1 high level independently correlate with elevated MACE risk in STEMI patients, implying its potency in identifying patients with poor prognoses.

Relationship between treatment delay and final infarct size in STEMI patients treated with abciximab and primary PCI.

Project description:BACKGROUND: Studies on the impact of time to treatment on myocardial infarct size have yielded conflicting results. In this study of ST-Elevation Myocardial Infarction (STEMI) treated with primary percutaneous coronary intervention (PCI), we set out to investigate the relationship between the time from First Medical Contact (FMC) to the demonstration of an open infarct related artery (IRA) and final scar size.Between February 2006 and September 2007, 89 STEMI patients treated with primary PCI were studied with contrast enhanced magnetic resonance imaging (ceMRI) 4 to 8 weeks after the infarction. Spearman correlation was computed for health care delay time (defined as time from FMC to PCI) and myocardial injury. Multiple linear regression was used to determine covariates independently associated with infarct size. RESULTS: An occluded artery (Thrombolysis In Myocardial Infarction, TIMI flow 0-1 at initial angiogram) was seen in 56 patients (63%). The median FMC-to-patent artery was 89 minutes. There was a weak correlation between time from FMC-to-patent IRA and infarct size, r = 0.27, p = 0.01. In multiple regression analyses, LAD as the IRA, smoking and an occluded vessel at the first angiogram, but not delay time, correlated with infarct size. CONCLUSIONS: In patients with STEMI treated with primary PCI we found a weak correlation between health care delay time and infarct size. Other factors like anterior infarction, a patent artery pre-PCI and effects of reperfusion injury may have had greater influence on infarct size than time-to-treatment per se.

Predicting mortality and no-reflow in STEMI patients using epicardial adipose tissue.

Project description:BackgroundAcute myocardial infarction is a leading cause of morbidity and mortality worldwide. It occurs when irreversible myocardial cell damage or death occurs. ST-segment elevation myocardial infarction (STEMI) is the most serious presentation of atherosclerotic coronary artery disease. STEMI results from the occlusion of a major coronary artery. Primary percutaneous coronary intervention (PCI) is the preferred reperfusion strategy. It should be performed by an experienced team within the shortest time possible from the first medical contact.HypothesisIncreased mortality risk and no-reflow in STEMI patients with epicardial adipose tissue thickness (EAT) more than 5 mm compared to STEMI patients with EAT less than 5 mm.MethodsThis study was conducted on 113 patients who presented to the cardiology department of Ain Shams university hospital with the first STEMI and underwent primary PCI. Medical treatment for STEMI was given to all subjects as per the guidelines. All patients underwent an echocardiographic evaluation of epicardial adipose tissue and left ventricular ejection fraction. Patients were divided into two groups using epicardial adipose tissue thickness of 5 mm as a cutoff point; this number was derived from the ROC curve. Group I: Included patients with EAT thickness less than 5 mm, including 44 patients (38.9%). Group II: Included patients with EAT thickness greater than 5 mm, including 69 patients (61.1%).ResultsThe current study showed that epicardial fat thickness significantly correlated with the no-reflow phenomenon in the cath lab and overall prognosis in patients with STEMI.ConclusionIncreased EAT thickness may be an independent predictor of the no-reflow phenomenon and mortality. Therefore, our study emphasizes that EAT thickness measured by echocardiography may provide additional and substantial information on the risk of no-reflow and mortality in STEMI patients.

Management of Major Bleeding Events in Patients Treated With Dabigatran for Nonvalvular Atrial Fibrillation: A Retrospective, Multicenter Review.

Project description:There are limited data on the clinical presentations and management of dabigatran-associated major bleeding outside the clinical trial setting. The aim of this study is to describe clinical characteristics, interventions, and outcomes in patients with dabigatran-associated major bleeding who present to the emergency department (ED).We performed a retrospective observational chart review study of dabigatran-treated patients with nonvalvular atrial fibrillation who presented with acute major bleeding to the ED. We searched electronic medical record databases cross-referencing medication lists and hemorrhage International Classification of Diseases, Ninth Revision (ICD-9) and ICD-10 codes. We studied the resulting charts to yield confirmed nonvalvular atrial fibrillation in patients with an index event of major bleeding and at least 1 dose of dabigatran in the 5 preceding days.The electronic search yielded 284 cases, and we assessed 93 as ineligible, leaving 191 in the final cohort. Of these, 118 patients (62%) had gastrointestinal hemorrhage; 36 (19%) had intracranial hemorrhage, 8 (4%) of which were nontraumatic cases and 28 (15%) traumatic. Thirty-six (19%) of the index events were in "other" locations and 1 (0.5%) "unknown." There were 12 deaths (6%): 8 from patients presenting with gastrointestinal bleeding events, 2 from intracranial hemorrhage (both nontraumatic), and 2 from other. Although RBC and plasma transfusions were common, only 11 patients (6%) received purified coagulation factors.Despite rare use of reversal strategies, mortality was low and outcomes were favorable, similar to reported outcomes from clinical trials, in this sample of patients with major bleeding while receiving dabigatran.
