2Recent advances in the diagnosis and treatment of acute myocardial infarction显示文摘The Third Universal Definition of Myocardial Infarction(MI) requires cardiac myocyte necrosis with an increase and/or a decrease in a patient's plasma of cardiac troponin(cT n) with at least one cT n measurement greater than the 99 th percentile of the upper normal reference limit during:(1) symptoms of myocardialischemia;(2) new significant electrocardiogram(ECG) ST-segment/T-wave changes or left bundle branch block;(3) the development of pathological ECG Q waves;(4) new loss of viable myocardium or regional wall motion abnormality identified by an imaging procedure; or(5) identification of intracoronary thrombus by angiography or autopsy.Myocardial infarction,when diagnosed,is now classified into five types.Detection of a rise and a fall of troponin are essential to the diagnosis of acute MI.However,high sensitivity troponin assays can increase the sensitivity but decrease the specificity of MI diagnosis.The ECG remains a cornerstone in the diagnosis of MI and should be frequently repeated,especially if the initial ECG is not diagnostic of MI.There have been significant advances in adjunctive pharmacotherapy,procedural techniques and stent technology in the treatment of patients with MIs.The routine use of antiplatelet agents such as clopidogrel,prasugrel or ticagrelor,in addition to aspirin,reduces patient morbidity and mortality.Percutaneous coronary intervention(PCI) in a timely manner is the primary treatment of patients with acute ST segment elevation MI.Drug eluting coronary stents are safe and beneficial with primary coronary intervention.Treatment with direct thrombin inhibitors during PCI is non-inferior to unfractionated heparin and glycoprotein Ⅱb/Ⅲa receptor antagonists and is associated with a significant reduction in bleeding.The intra-coronary use of a glycoprotein Ⅱb/Ⅲa antagonist can reduce infarct size.Pre- and post-conditioning techniques can provide additional cardioprotection.However,the incidence and mortality due to MI continues to be high despite all these recent advances.The initial ten year experience with autologous human bone marrow mononuclear cells(BMCs) in patients with MI showed modest but significant increases in left ventricular(LV) ejection fraction,decreases in LV endsystolic volume and reductions in MI size.These studies established that the intramyocardial or intracoronary administration of stem cells is safe.However,many of these studies consisted of small numbers of patients who were not randomized to BMCs or placebo.The recent LateT ime,Time,and Swiss Multicenter Trials in patientswith MI did not demonstrate significant improvement in patient LV ejection fraction with BMCs in comparison with placebo.Possible explanations include the early use of PCI in these patients,heterogeneous BMC populations which died prematurely from patients with chronic ischemic disease,red blood cell contamination which decreases BMC renewal,and heparin which decreases BMC migration.In contrast,cardiac stem cells from the right atrial appendage and ventricular septum and apex in the SCIPIO and CADUCEUS Trials appear to reduce patient MI size and increase viable myocardium.Additional clinical studies with cardiac stem cells are in progress.Koushik Reddy Asma Khaliq Robert J Henning 2015World Journal of Cardiology2015,7,5:107
3Ischemia/reperfusion injury and cardioprotective mechanisms:Role of mitochondria and reactive oxygen species显示文摘Reperfusion therapy must be applied as soon as possible to attenuate the ischemic insult of acute myocardial infarction(AMI).However reperfusion is responsible for additional myocardial damage,which likely involves opening of the mitochondrial permeability transition pore(mPTP).In reperfusion injury,mitochondrial damage is a determining factor in causing loss of cardiomyocyte function and viability.Major mechanisms of mitochondrial dysfunction include the long lasting opening of mPTPs and the oxidative stress resulting from formation of reactive oxygen species(ROS).Several signaling cardioprotective pathways are activated by stimuli such as preconditioning and postconditioning,obtained with brief intermittent ischemia or with pharmacological agents.These pathways converge on a common target,the mitochondria,to preserve their function after ischemia/reperfusion.The present review discusses the role of mitochondria in cardioprotection,especially the involvement of adenosine triphosphate-dependent potassium channels,ROS signaling,and the mPTP.Ischemic postconditioning has emerged as a new way to target the mitochondria,and to drastically reduce lethal reperfusion injury.Several clinical studies using ischemic postconditioning during angioplasty now support its protective effects,and an interesting alternative is pharmacological postconditioning.In fact ischemic postconditioning and the mPTP desensitizer,cyclosporine A,have been shown to induce comparable protection in AMI patients.Maria-Giulia Perrelli Pasquale Pagliaro Claudia Penna 2011World Journal of Cardiology2011,3,6:64
4Lipoprotein-associated phospholipase A2 prognostic role in atherosclerotic complications显示文摘Atherosclerosis manifests itself clinically at advanced stages when plaques undergo hemorrhage and/or rupture with superimposed thrombosis, thus abruptly stopping blood supply. Identification of markers of plaque destabilization at a pre-clinical stage is, therefore, a major goal of cardiovascular research. Promising results along this line were provided by studies investigating the lipoprotein-associated phospholipase A2(Lp-PLA2), a member of phospholipase A2 proteins family that plays a key role in the metabolism of pro-inflammatory phospholipids, as oxidized low-density lipoproteins, and in the generation of pro-atherogenic metabolites, including lysophosphatidylcholine and oxidized free fatty acids. We herein review the experimental and clinical studies supporting use of Lp-PLA2 activity for predicting cardiovascular events. To his end we considered not only Lp-PLA2 activity and mass, but also Lp-PLA2 gene variations and their association with incident coronary artery disease, stroke, and cardiovascular mortality. Based on these evidences the major scientific societies have included in their guidelines the measurement of Lp-PLA2 activity among the biomarkers that are useful in risk stratification of adult asymptomatic patients at intermediate cardiovascular risk. The results of two recently published major clinical trials with the LpPLA2 inhibitor darapladib, which seem to challenge the pathogenic role of Lp-PLA2, will also be discussed.Giuseppe Maiolino Valeria Bisogni Giacomo Rossitto Gian Paolo Rossi 2015World Journal of Cardiology2015,7,10:66
5在心血管的疾病的先进 glycation 结束产品的角色显示文摘 Advanced glycation end products(AGEs) are produced through the non enzymatic glycation and oxidation of proteins,lipids and nucleic acids.Enhanced formation of AGEs occurs particularly in conditions associated with hyperglycaemia such as diabetes mellitus(DM).AGEs are believed to have a key role in the development and progression of cardiovascular disease in patients with DM through the modif ication of the structure,function and mechanical properties of tissues through crosslinking intracellular as well as extracellular matrix proteins and through modulating cellular processes through binding to cell surface receptors [receptor for AGEs(RAGE)].A number of studies have shown a correlation between serum AGE levels and the development and severity of heart failure(HF).Moreover,some studies have suggested that therapies targeted against AGEs may have therapeutic potential in patients with HF.The purpose of this review is to discuss the role of AGEs in cardiovascular disease and in particular in heart failure,focussing on both cellular mechanisms of action as well as highlighting how targeting AGEs may represent a novel therapeutic strategy in the treatment of HF.Zeinab Hegab Stephen Gibbons Ludwig Neyses Mamas A Mamas 2012World Journal of Cardiology2012,4,4:58
6Effect of phosphodiesterase-5 inhibition on exercise capacity and clinical status in heart failure with preserved ejection fraction:A randomized clinical trial显示文摘Objective To determine the effect of the phosphodiesterase-5 inhibitor sildenafil compared with placebo on exercise capacity and clinical status in HFPEF.Design Multicenter,double-blind,placebo-controlled,parallel-group,randomized clinical trial of 216 stable outpatients with HF,ejection fraction ≥50%,elevated N-terminal brain-type natriuretic peptide or elevated invasively measured filling pressures,and reduced exercise capacity.Participants were randomized from October 2008 through February 2012 at 26 centers in North America.Follow-up was through August 30,2012.Interventions Sildenafil(n = 113) or placebo(n = 103) administered orally at 20 mg,3 times daily for 12 weeks,followed by 60 mg,3 times daily for 12 weeks.Main Outcome Measures Primary end point was change in peak oxygen consumption after 24 weeks of therapy.Secondary end points included change in 6-minute walk distance and a hierarchical composite clinical status score(range,1-n,a higher value indicates better status;expected value with no treatment effect,95) based on time to death,time to cardiovascular or cardiorenal hospitalization,and change in quality of life for participants without cardiovascular or cardiorenal hospitalization at 24 weeks.Results Median age was 69 years,and 48% of patients were women.At baseline,median peak oxygen consumption(11.7 mL /kg /min) and 6-minute walk distance(308 m) were reduced.The median E /e'(16),left atrial volume index(44 mL /m 2),and pulmonary artery systolic pressure(41 mm Hg) were consistent with chronically elevated left ventricular filling pressures.At 24 weeks,median(IQR) changes in peak oxygen consumption(mL /kg /min) in patients who received placebo(-0.20 [IQR,-0.70 to 1.00]) or sildenafil(-0.20 [IQR,-1.70 to 1.11]) were not significantly different(P = 0.90) in analyses in which patients with missing week-24 data were excluded,and in sensitivity analysis based on intention to treat with multiple imputation for missing values(mean between-group difference,0.01 mL /kg /min,[95% CI,-0.60 to 0.61]).The mean clinical status rank score was not significantly different at 24 weeks between placebo(95.8) and sildenafil(94.2)(P = 0.85).Changes in 6-minute walk distance at 24 weeks in patients who received placebo(15.0 m [IQR,-26.0 to 45.0]) or sildenafil(5.0 m [IQR,-37.0 to 55.0];P = 0.92) were also not significantly different.Adverse events occurred in 78 placebo patients(76%) and 90 sildenafil patients(80%).Serious adverse events occurred in 16 placebo patients(16%) and 25 sildenafil patients(22%).Conclusion and Relevance Among patients with HFPEF,phosphodiesterase-5 inhibition with administration of sildenafil for 24 weeks,compared with placebo,did not result in significant improvement in exercise capacity or clinical status.2013South China Journal of Cardiology2013,14,1:53
7Myocardial reperfusion injury and oxidative stress: Therapeutic opportunities显示文摘Acute myocardial infarction(AMI) is the leading cause of death worldwide. Its associated mortality, morbidity and complications have significantly decreased with the development of interventional cardiology and percutaneous coronary angioplasty(PCA) treatment, which quick-ly and effectively restore the blood flow to the area previously subjected to ischemia. Paradoxi-cally, the restoration of blood flow to the ischemic zone leads to a massive production of reactive oxygen species(ROS) which generate rapid and severe damage to biomolecules, generating a phenomenon called myocardial reperfusion injury(MRI). In the clinical setting, MRI is associated with multiple complications such as lethal reperfusion, no-reflow, myocardial stunning, and reperfusion arrhythmias. Despite significant advances in the understanding of the mechanisms accounting for the myocardial ischemia reperfusion injury, it remains an unsolved problem. Although promising results have been obtained in experimental studies(mainly in animal models), these benefits have not been translated into clinical settings. Thus, clinical trials have failed to find benefits from any therapy to prevent MRI. There is major evidence with respect to the contribution of oxidative stress to MRI in cardiovascular diseases. The lack- of consistency between basic studies and clinical trials is not solely based on the diversity inherent in epidemiology but is also a result of the methodological weak-nesses of some studies. It is quite possible that pharmacological issues, such as doses, active ingredients, bioavailability, routes of administration, co-therapies, startup time of the drug intervention,and its continuity may also have some responsibility for the lack- of consistency between different studies. Furthermore, the administration of high ascorbate doses prior to reperfusion appears to be a safe and rational therapy against the development of oxidative damage associated with myocardial reperfusion. In addition, the association with N-acetylcysteine(a glutathione donor) and deferoxamine(an iron chelator) could improve the antioxidant cardioprotection by ascorbate, mak-ing it even more effective in preventing myocardial reperfusion damage associated with PCA following AMI.Jaime González-Montero Roberto Brito Abraham IJ Gajardo Ramón Rodrigo 2018World Journal of Cardiology2018,10,9:56

11Diagnosis and management challenges of in-stent restenosis in coronary arteries显示文摘Over the course of the 3 decades, percutaneous coronary intervention(PCI) with stent implantation transformed the practice of cardiology. PCI with stenting is currently the most widely performed procedure for the treatment of symptomatic coronary disease. In large trials, drugeluting stents(DES) have led to a significant reduction in in-stent restenosis(ISR) rates, one of the major limitations of bare-metal stents. Due to these favorable findings, DES was rapidly and widely adopted enabling more complex coronary interventions. Nevertheless, ISR remains a serious concern as late stent complications. ISR mainly results from aggressive neointimal proliferation and neoatherosclerosis. DES-ISR treatment continues to be challenging complications for interventional cardiologists.M Chadi Alraies Fahed Darmoch Ramyashree Tummala Ron Waksman 2017World Journal of Cardiology2017,9,8:50
12Two-dimensional speckle tracking echocardiography for the assessment of atrial function显示文摘Echocardiography is the most common diagnostic method for assessing atrial function but the technique has some limitations. Traditionally, assessment of left atrial function has been performed by measuring volumes with 2D echocardiography. Additionally, it can be assessed with transmitral Doppler and pulmonary vein Doppler. Recently, an alternative method has been incorporated, namely, measurement of myocardial deformation with color tissue Doppler-derived strain. However, this method has several limitations, such as suboptimal reproducibility, angle-dependence, signal artifacts and the fact that it only measures regional strain and does not obtain information about the curved portion of the atrial roof. To overcome these limitations in the quantification of atrial function, the use of speckle tracking echocardiography (STE) strain has been proposed. This technique is not derived from Doppler but rather from 2D echocardiography; it is angle-independent and allows one to measure global as well as regional atrial strain. In this editorial, we describe the physical and pathophysiological concepts of STE and underline the clinical usefulness of this new technique.Tomás Francisco Cianciulli María Cristina Saccheri Jorge Alberto Lax Alejandra Marina Bermann Daniel Ernesto Ferreiro 2010World Journal of Cardiology2010,2,7:39
13Clinical importance of aspirin and clopidogrel resistance显示文摘Aspirin and clopidogrel are important components of medical therapy for patients with acute coronary syndromes, for those who received coronary artery stents and in the secondary prevention of ischaemic stroke. Despite their use, a significant number of patients experience recurrent adverse ischaemic events. Interindividual variability of platelet aggregation in response to these antiplatelet agents may be an explanation for some of these recurrent events, and small trials have linked 'aspirin and/or clopidogrel resistance', as measured by platelet function tests, to adverse events. We systematically reviewed all available evidence on the prevalence of aspirin/clopidogrel resistance, their possible risk factors and their association with clinical outcomes. We also identified articles showing possible treatments. After analyzing the data on different laboratory methods, we found that aspirin/clopidogrel resistance seems to be associated with poor clinical outcomes and there is currently no standardized or widely accepted definition of clopidogrel resistance. Therefore, we conclude that specific treatment recommendations are not established for patients who exhibit high platelet reactivity during aspirin/clopidogrel therapy or who have poor platelet inhibition by clopidogrel.Gergely Feher Andrea Feher Gabriella Pusch Katalin Koltai Antal Tibold Beata Gasztonyi Elod Papp Laszlo Szapary Gabor Kesmarky Kalman Toth 2010World Journal of Cardiology2010,2,7:36

18Red blood cell distribution width in heart failure: A narrative review显示文摘The red blood cell distribution width(RDW) is a simple, rapid, inexpensive and straightforward hematological parameter, reflecting the degree of anisocytosis in vivo. The currently available scientific evidence suggests that RDW assessment not only predicts the risk of adverse outcomes(cardiovascular and all-cause mortality, hospitalization for acute decompensation or worsened left ventricular function) in patients with acute and chronic heart failure(HF), but is also a significant and independent predictor of developing HF in patients free of this condition. Regarding the biological interplay between impaired hematopoiesis and cardiac dysfunction, many of the different conditions associated with increased heterogeneity of erythrocyte volume(i.e., ageing, inflammation, oxidative stress, nutritional deficiencies and impaired renal function), may be concomitantly present in patients with HF, whilst anisocytosis may also directly contribute to the development and worsening of HF. In conclusion, the longitudinal assessment of RDW changes over time may be considered an efficient measure to help predicting the risk of both development and progression of HF.Giuseppe Lippi Gianni Turcato Gianfranco Cervellin Fabian Sanchis-Gomar 2018World Journal of Cardiology2018,10,2:37
19Diagnostic accuracy of a deep learning approach to calculate FFR from coronary CT angiography显示文摘Background The computational fluid dynamics(CFD)approach has been frequently applied to compute the fractional flow reserve(FFR)using computed tomography angiography(CTA).This technique is efficient.We developed the DEEPVESSEL-FFR platform using the emerging deep learning technique to calculate the FFR value out of CTA images in five minutes.This study is to evaluate the DEEPVESSEL-FFR platform using the emerging deep learning technique to calculate the FFR value from CTA images as an efficient method.Methods A single-center,prospective study was conducted and 63 patients were enrolled for the evaluation of the diagnostic performance of DEEPVESSEL-FFR.Automatic quantification method for the three-dimensional coronary arterial geometry and the deep learning based prediction of FFR were developed to assess the ischemic risk of the stenotic coronary arteries.Diagnostic performance of the DEEPVESSEL-FFR was assessed by using wire-based FFR as reference standard.The primary evaluation factor was defined by using the area under receiver-operation characteristics curve(AUC)analysis.Results For per-patient level,taking the cut-off value<0.8 referring to the FFR measurement,DEEPVESSEL-FFR presented higher diagnostic performance in determining ischemia-related lesions with area under the curve of 0.928 compare to CTA stenotic severity 0.664.DEEPVESSEL-FFR correlated with FFR(R=0.686,P<0.001),with a mean di&ference of-0.006士0.0091(P=0.619).The secondary evaluation factors,indicating per vessel accuracy,sensitivity,specificity,positive predictive value,and negative predictive value were 87.3%,97.14%,75%,82.93%,and 95.45%,respectively.Conclusion DEEPVESSEL-FFR is a novel method that allows efficient assessment of the functional significance of coronary stenosis.Zhi-Qiang WANG Yu-Jie ZHOU Ying-Xin ZHAO Dong-Mei SHI Yu-Yang LIU Wei LIU Xiao-Li LIU Yue-Ping LI 2019Journal of Geriatric Cardiology2019,16,1:37
20Role of Helicobacter pylori infection in pathogenesis of atherosclerosis显示文摘Though a century old hypothesis, infection as a cause for atherosclerosis is still a debatable issue. Epidemiological and clinical studies had shown a possible association but inhomogeneity in the study population and study methods along with potential confounders have yielded conflicting results. Infection triggers a chronic inflammatory state which along with other mechanisms such as dyslipidemia, hyper-homocysteinemia, hypercoagulability, impaired glucose metabolism and endothelial dysfunction, contribute in pathogenesis of atherosclerosis. Studies have shown a positive relations between Cytotoxic associated gene-A positive strains of Helicobacter pylori and vascular diseases such as coronary artery disease and stroke. Infection mediated genetic modulation is a new emerging theory in this regard. Further large scale studies on infection and atherosclerosis focusing on multiple pathogenetic mechanisms may help in refining our knowledge in this aspect.Rajesh Vijayvergiya Ramalingam Vadivelu 2015World Journal of Cardiology2015,7,3:37
