Safety and Efficacy of Bivalirudin in High-risk Patients Admitted Through the Emergency Department

Objectives: The objective was to assess the safety and efficacy of bivalirudin monotherapy in patients with high-risk acute coronary syndrome (ACS) presenting to the emergency department (ED). Methods: Data from the Acute Catheterization and Urgent Intervention Triage StrategY (ACUITY) trial were used to conduct a post hoc subgroup analysis of high-risk ACS patients (cardiac biomarker elevation or ST-segment deviation) who initially presented to the ED. The ACUITY trial randomized patients to receive heparin (unfractionated [UFH] or enoxaparin) plus glycoprotein IIb/IIIa inhibition (GPI), bivalirudin plus GPI, or bivalirudin monotherapy. Endpoints included composite ischemia, major bleeding (not coronary artery bypass graft (CABG) related), and net clinical outcome (major bleeding plus composite ischemia). Results: Of 13,819 participants in the ACUITY trial, 6,441 presented initially to the ED, met high-risk criteria, and were included in the primary analysis. Bivalirudin alone when compared to heparin plus GPI, after adjusting for covariates, was associated with an improvement in net clinical outcome (12.3% vs. 14.3%, adjusted odds ratio [OR] = 0.81, 95% confidence interval [CI] = 0.66 to 0.99), similar composite ischemia (9.3% vs. 9.1%, adjusted OR = 0.98, 95% CI = 0.77 to 1.24), and less major bleeding (4.0% vs. 6.8%, adjusted OR = 0.57, 95% CI = 0.42 to 0.75). Bivalirudin plus GPI when compared to heparin plus GPI had similar net clinical outcome (13.8% vs. 14.3%, adjusted OR = 0.91, 95% CI = 0.75 to 1.11), composite ischemia (8.8% vs. 9.1%, adjusted OR = 0.87, 95% CI = 0.69 to 1.11), and major bleeding (6.8% vs. 6.8%, adjusted OR = 1.01, 95% CI = 0.79 to 1.30). Conclusions:  Bivalirudin monotherapy decreases major bleeding while providing similar protection from ischemic events compared to heparin plus GPI in patients with high-risk ACS admitted through the ED.     

综合心脏康复治疗对冠状动脉硬化性心脏病介入术后患者的效果

目的探讨综合心脏康复治疗对冠状动脉硬化性心脏病（coronary heart disease,CHD）介入治疗术后患者的效果。方法2009年7月至2011年3月便利抽样法选择广东医学院附属医院心血管内科CHD介入治疗术后患者180例为研究对象,按随机数字表法将其分为观察组和对照组,每组90例。住院期间,观察组患者介入治疗后采取综合心脏康复治疗及护理,对照组患者介入治疗后只给予常规护理。随访1年,统计两组患者介入治疗后1年内心功能情况以及心脏缺血性事件复发再入院情况。结果观察组患者心功能各项指标均较对照组有改善,差异均有统计学意义（均P〈0．01）。观察组患者因心脏缺血性事件复发再人院8例,占8．89％;而对照组患者因心脏缺血性事件复发再入院22例,占24．44％,差异有统计学意义（P〈0．01）。结论综合心脏康复治疗及护理可明显改善CHD介入治疗术后患者的心功能,增强患者治疗的信心,从而促进康复,对减少心脏缺血性事件的发生具有非常重要的现实意义。     

Dual Antiplatelet Therapy for Long-term Secondary Prevention of Atherosclerotic Cardiovascular Events

PurposeDual antiplatelet therapy (DAPT) with aspirin and a P2Y₁₂ inhibitor is currently recommended to prevent further ischemic events after percutaneous coronary intervention and acute coronary syndrome (ACS). Guidelines currently recommend a minimum of 6 months after elective drug-eluting stent placement and at least 12 months of DAPT after ACS; however, the benefits of prolonged treatment are unclear. The purpose of this review was to conduct a detailed examination of the data refuting or supporting the use of DAPT beyond 1 year in patients with ACS and in patients receiving percutaneous coronary intervention with stenting.MethodsA search of PubMed was performed to identify articles published in the last 20 years that addressed the role of DAPT beyond 12 months’ duration.FindingsA number of studies have shown ischemic benefits associated with prolonging DAPT beyond 12 months, but this finding is dependent on the patient population studied and the quality of the study design. Many studies also show that longer duration therapy has been associated with increased bleeding risk. In patients with previous myocardial infarction completing at least 1 year of DAPT, continuing DAPT with a reduced dose of ticagrelor 60 mg BID is a regimen to be considered for these patients; in general ACS patients, a reduced dose of 60 mg BID of ticagrelor after the first year of DAPT should be considered; and in the post–percutaneous coronary intervention patients, DAPT beyond 1 year should be considered after careful evaluation of the patient's thrombotic and bleeding risks.ImplicationsThe duration of DAPT, and the choice of P2Y₁₂ inhibitor, should be tailored to the individual patient. To optimize patient outcomes, the benefits and risks associated with prolonging DAPT need to be evaluated, considering comorbidities and the presence of bleeding and ischemic risk factors. Despite some limitations, risk scores, such as the DAPT score, are available to help guide decisions for the best approach for each patient.     

Long-Term Follow-Up of Patients with Refractory Heart Failure and Myocardial Ischemia Treated with Cardiac Resynchronization Therapy

Studies in patients without coronary artery disease have shown the restoration of glucose metabolism by cardiac resynchronization therapy (CRT) without changes in myocardial perfusion. We report on the long-term outcome of CRT in 24 patients with severe heart failure (HF) and advanced coronary artery disease not amenable for revascularization. All patients had documented myocardial ischemia on stress ⁹⁹Tc-sestamibi single-photon emission computed tomography, and all underwent successful implantations of CRT systems. The mean left ventricular ejection fraction was 21%± 4%, 19 patients (79%) had anginal complaints and 20 (83%) had diffuse three-vessel disease. During a follow-up of 13 ± 0.7 months, two patients died suddenly and one died of progressive HF. Among survivors, functional capacity decreased from New York Heart Association class 3.2 ± 1.4 to 2.1 ± 1.0 (P < 0.01), and the Minnesota questionnaire quality-of-life scores decreased from 43 ± 15 to 28 ± 13 (P < 0.01). Despite an increase from 264 ± 104 to 385 ± 121 m in distance walked in 6 minutes (P < 0.01), the number of anginal attacks/week remained unchanged (4.7 ± 0.7 to 4.5 ± 0.6). Patients with advanced HF, stable angina, and documented myocardial ischemia may undergo safe and successful implantations of CRT systems.

Temporal age‐related changes in spectral,fractal and complexity characteristics of heart rate variability

Cross‐sectional studies have suggested that heart rate (HR) variability, analysed using traditional time and frequency domain methods, is related to ageing, but no longitudinal studies have estimated the age dependence of HR fluctuation. This study evaluated temporal age‐related changes in 12‐h measures of HR variability among 109 patients with coronary artery disease (CAD), who underwent repeat Holter recordings at 32‐month intervals. Time and frequency domain measures, along with fractal and complexity measures of HR variability, were determined at the baseline and after 32 months. Changes in HR dynamics were compared with various laboratory variables, exercise data and angiographic progression of CAD. Traditional time and frequency domain measures of HR variability did not change significantly during the follow‐up, but the power‐law scaling slope decreased from ?1·29 ± 0·20 to ?1·36 ± 0·23 (P<0·01) and the short‐term fractal exponent (α₁) of HR dynamics from 1·29 ± 0·14–1·22 ± 0·18 (P<0·001). The approximate entropy value also decreased from 1·00 ± 0·19 to 0·95 ± 0·18 (P<0·05). The changes in HR behaviour were not related to demographic data, laboratory values or angiographic progression of CAD. Only a weak correlation was observed between the change in the power‐law slope and the baseline glucose value (P<0·05). This longitudinal study shows that the fractal characteristics of HR dynamics and the complexity properties of R‐R intervals undergo rapid changes along with ageing, and that fractal and complexity analysis techniques are more sensitive than traditional analysis methods in documenting temporal age‐related changes in HR behaviour.     

急性心肌梗死患者脂蛋白（a）与冠状动脉病变程度的关系

目的探讨急性心肌梗死（AMI）患者血浆脂蛋白（a）[Lp（a）]与冠状动脉病变程度的关系。方法对136例AMI患者进行血脂检测及冠状动脉造影检查,按血浆Lp（a）水平分为低Lp（a）组（〈300 mg/L,46例）和高Lp（a）组（≥300 mg/L,90例）,比较两组血清Lp（a）浓度及冠状动脉病变特点的差异,应用logistic回归分析及逐步回归分析,观察以上指标与冠状动脉狭窄程度的相关性。结果高Lp（a）组Gensini积分、多支病变构成比例、梗死相关动脉（IRA）闭塞率分别为（145.6±36.2）分、58.9%、86.7%,高于低Lp（a）组（96.8±21.7）分、23.9%、56.5%;高Lp（a）组梗死相关动脉心肌梗死溶栓治疗试验（TIMI）积分为（1.58±0.88）分,低于低Lp（a）组的（2.31±1.07）分（P〈0.05）;回归分析发现,Lp（a）是冠状动脉病变程度I、RA闭塞率和TIMI评分的主要影响因素（P〈0.05或〈0.01）。结论 AMI患者血浆Lp（a）水平,与冠状动脉狭窄程度,IRA血流量、闭塞率及密切相关。     

Management of Acute Coronary Syndromes in Patients with Diabetes: Implications of the FREEDOM Trial

Background

Diabetes mellitus (DM) is a powerful independent risk factor for multivessel, diffuse coronary artery disease (CAD). The optimal coronary revascularization strategy in DM is not clearly defined, but past trials have suggested an advantage for coronary artery bypass grafting (CABG). Recently, the Future Revascularization Evaluation in Patients with Diabetes Mellitus: Optimal Management of Multivessel Disease (FREEDOM) trial found patients randomized to CABG had lower rates of death and myocardial infarction (MI) compared with those randomized to percutaneous coronary intervention (PCI).

Objective

This article reviews the contemporary management of patients with DM presenting with acute coronary syndromes, particularly ST-elevation MI, in the post-FREEDOM era.

Methods

We undertook a comprehensive review of published literature addressing trials in this field performed to address current knowledge both in the pre- and post-FREEDOM era.

Results

The implications of FREEDOM for patients with acute coronary syndrome are that CABG provides a significant benefit, compared with PCI with drug-eluting stents, to patients with DM and multivessel coronary artery disease; and that patients similar to those enrolled in FREEDOM should receive CABG in preference to PCI. The relevance of FREEDOM’s findings to the large proportion of patients who would not meet inclusion criteria—including patients with an acute coronary syndrome undergoing an early or emergent invasive strategy, remains uncertain.

Discussion

FREEDOM’s outcomes have generated uncertainty regarding best practice once thrombolysis in myocardial infarction grade 3 flow is re-established in patients with DM and multivessel disease. Current interventional guidelines recommend optimally treating the culprit artery; however, decisions made at the time of revascularization influence future revascularization strategies, particularly stent choice and resultant P2Y₁₂ receptor antagonist therapy. The preferred method for future revascularization may be questioned if the patient's residual coronary stenoses do not, post-PCI, meet the FREEDOM inclusion criteria, or where the left anterior descending artery is the infarct-related artery, and after left anterior descending artery PCI the patient would not receive an internal mammary graft. The management of residual disease and the preferred (further) revascularization strategy needs to be tested in an appropriately powered randomized trial.

Conclusions

The optimal revascularization strategy in patients with acute coronary syndrome, diabetes, and multivessel disease, in particular those with ST elevation, is unclear, and not guided by level A (or B) evidence. Currently CABG is favored over PCI, and an individually tailored, collaborative approach, guided by a multidisciplinary heart team, should be employed.     

急性冠脉综合征患者血清P-选择素、LDL-C水平的变化及意义

目的探讨急性冠脉综合征(ACS)患者血清P-选择素、低密度脂蛋白胆固醇(LDL-C)水平的变化及临床意义。方法采用自动生化分析仪检测80例ACS患者(ACS组)、80例稳定性心绞痛患者(SAP组)和80例健康体检者(正常对照组)血清LDL-C水平,使用自动生化分析仪、采用酶联免疫分析法检测3组血清P-选择素水平。结果 ACS组、SAP组血清P-选择素、LDL水平均明显高于正常对照组(P<0.05或P<0.01),ACS组血清P-选择素水平明显高于SAP组(P<0.05),ACS组血清LDL水平与SAP组比较差异无统计学意义(P>0.05)。相关分析结果显示,ACS组血清P-选择素水平与血清LDL-C水平呈正相关(r=0.349,P<0.01)。结论检测ACS患者血清P-选择素、LDL-C水平的变化对ACS的发生发展均具有重要的临床意义,血清P-选择素浓度升高可以作为ACS发生的预测指标。

乌鲁木齐地区维汉两民族中冠心病患者糖蛋白Ⅲa基因多态性研究

Objective To determine whether a variant(PlA2) of the membrane glycoprotein IIIa(GP IIIa) gene is associated with CAD. Furthermore,the association of the polymorphism with the classical risk factors was analyzed.Methods Blood was drawn from 105 patients (pt) and 56 controls, some of those undergoing angiography. A 266 base pair fragment of the GP IIIa gene was amplified by the polymerase chain reaction(PCR) and digested with the MspI restriction enzyme. Genotypes were identified after electrophoresis of digestion products in 2.0% agarose gel. Results Of the 105 patients(pt), 65 had acute (n=19) or previous MI,20 had unstable angina (UAP), and 20 had stable angina(SAP).The PlA2 allele was carried by 0% of CAD pt versus 1.8% of Non CAD control subjects in Chinese Urumqi Uygur and Han population. The PlA2 allele was carried by 0% of CAD pt versus 7.7% of Non CAD control subjects in Uygur population.The PlA2 allele was found in 0% of CAD pt versus 0% of Non CAD control subjects in Han population.Conclusions The PlA2 variant of the gene GP IIIa is not associated with CAD in Uygur population and Han population in Urumqi city of Xinjiang Uygur Autonomous Region.     

Predischarge education improves adherence to a healthy lifestyle among Jordanian patients with acute coronary syndrome

Risk factor reduction and modification of patient lifestyle have become the focus of secondary prevention and cardiac rehabilitation programs. Considering the scarcity of resources in developing countries, nurses can potentially provide great benefit to acute coronary syndrome patients by utilizing hospital time to teach the patients how to lower their risk for recurrence and adopt healthier lifestyles after discharge. The purpose of this study was to identify the effectiveness of a predischarge education on acute coronary syndrome patients' lifestyles. Quasi‐experimental pretest–post‐test design was used. The patients assigned to the experimental group were offered predischarge education that stimulates lifestyle modification and adoption of a healthier lifestyle. The experimental group scored significantly higher than the control group in three lifestyle components – health responsibilities, nutrition, and interpersonal relations. In conclusion, predischarge education helps motivate acute coronary syndrome patients to adhere to a healthy lifestyle postdischarge. Therefore, nurses must be educated and prepared to be qualified health educators, and health education should continue as one of the most important daily nursing practices, thus it is invested in the preparation of acute coronary patients' discharge plan.

Tissue factor serum levels and the risk of future coronary artery disease in apparently healthy men and women: the EPIC-Norfolk prospective population study

INTRODUCTION: Tissue factor (TF) has been implicated in coronary artery disease (CAD). High levels of circulating TF are found in patients with acute atherothrombotic events. Whether high serum TF levels predict risk of future CAD independent of known risk factors remains unknown. METHODS: We conducted a prospective case-control study nested in the European Prospective Investigation into Cancer and Nutrition (EPIC)-Norfolk population study. Cases (n=1037) were apparently healthy men and women, aged 45-79 years, who developed fatal or non-fatal CAD during follow-up. Controls (n=2005) were matched by age, sex, and enrolment time. Serum TF levels were measured using high-affinity antibodies. RESULTS: In men, median TF levels were not significant higher in cases than in controls (59.0 pg mL-1, range: 16.7-370.4 vs. 54.9 pg mL-1, range: 16.2-452.4). In women, median TF levels were not significant higher in controls than in cases (73.4 pg mL-1, range: 16.7-492.3 vs. 50.5 pg mL-1, range: 16.5-376.7). The incidence of smoking was about double in the lowest compared with the highest TF quartile. Correcting for sex, age, body mass index, smoking, diabetes, systolic blood pressure, low-density lipoprotein-cholesterol, high-density lipoprotein-cholesterol and C-reactive protein levels, the risk of future CAD was 1.05 (95% CI: 0.81-1.36) for people in the highest TF quartile, compared with those in the lowest (P-value for linearity=0.8). CONCLUSION: High levels of serum TF were not independently associated with an increased risk of future CAD in apparently healthy individuals.

心理干预对急性冠状动脉综合征伴抑郁患者心功能的影响

目的探讨心理干预对急性冠状动脉综合征(ACAS)患者抑郁情绪及心脏功能的影响。方法应用抑郁自评量表(SDS)评价168例ACAS患者,其中102例并发抑郁的ACAS患者随机分成心理干预组52例与对照组50例,对照组给予常规心血管药物治疗,干预组则在常规心血管药物治疗的基础上进行综合心理干预,抑郁情绪严重者服用适量抗抑郁药物治疗,疗程1个月;治疗前后应用抑郁自评量表(SDS)及汉密顿抑郁量表(HRSD)进行评估,并应用超声心动图对患者的左心室射血分数(LVEF)进行评价。结果本组ACAS患者抑郁发生率为60.7%。1个月后,心理干预组SDS及HRSD评分显著低于对照组[(21.79±5.58)vs(36.95±6.96);(9.89±4.42)vs(18.04±6.54),P<0.05~0.01],LVEF显著高于对照组[(55.6±6.1)%vs(47.2±4.3)%,P<0.05]。结论在心血管药物治疗的基础上,心理干预能有效消除ACAS患者的抑郁情绪,改善心脏功能。     

冠心病患者血清脂蛋白(a)水平临床分析

目的:评价血清脂蛋白(a)[Lp(a)]在冠心病(CHD)诊疗中的地位和作用。方法:取250例患者血清进行测定Lp(a)和总胆固醇(TC)、甘油三脂(TG)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C),其中正常组63例,冠心病组89例,高血压病组52例,其它类心脏病组46例。结果:①冠心病组血清Lp(a)较其他3组均显著升高(P<0.01),高血压组和其它类心脏病组与正常组Lp水平比较,无显著统计学差异(P>0.05);②冠心病单支病变组、2支病变组、2支以上病变组各组间血清Lp(a)水平比较差异均有统计学意义;③冠心病非急性心肌梗死患者与急性心肌梗死患者血清Lp(a)浓度无明显差异(P>0.05);④多因素逐步回归分析表明,Lp(a)与TG、TC、HDL-C之间无显著相关。结论:高Lp(a)水平是冠心病的独立危险因子,对于预测冠心病的发生有一定的价值,但对于预测冠心病急性心血管病事件的发生却未见明显的优势。
