  • 文章类型: Journal Article
    冠状动脉非靶病变的快速进展对于确定未来的心血管事件至关重要。预测非靶病变快速进展的临床因素尚不清楚。这项研究的目的是确定冠状动脉非靶病变快速进展和血运重建的临床预测因素。
    连续进行两次冠状动脉造影的冠心病患者被纳入研究。在两种程序中都识别并评估了所有冠状动脉非靶病变。采用多变量Cox回归分析探讨冠状动脉非靶病变快速进展或血运重建的临床危险因素。
    共纳入1255例患者和1670个病灶。在这群患者中,239(19%)进展迅速,186(14.8%)进行了血运重建。在病变级别,251例(15.0%)进展迅速,194例(11.6%)接受血运重建。进展迅速的患者,病变血运重建和心肌梗死的发生率明显较高。在多变量分析中,高血压(危险比[HR],0.76;95%置信区间[95%CI],0.58-1.00;p=0.049),ST段抬高型心肌梗死(STEMI)(HR,1.46;95%CI,1.03-2.07;p=0.035),糖化血红蛋白(HR,1.16;95%CI,1.01-1.33;p=0.039)和病变分类(B2/C与A/B1)(HR,1.73;95%CI,1.27-2.35;p=0.001)是与快速进展相关的显著因素。甘油三酯的水平(HR,1.10;95%CI,1.00-1.20;p=0.040)和病变分类(B2/C与A/B1)(HR,1.53;95%CI,1.09-2.14;p=0.014)是病变血运重建的预测因子。
    高血压,STEMI,糖化血红蛋白和病变分类可作为冠状动脉非靶病变快速进展的预测因子。甘油三酯水平和病变分类可以预测非靶病变的血运重建。为了预防未来的心血管事件,应更加重视这些因素的患者。
    UNASSIGNED: Rapid progression of coronary non-target lesions is essential for the determination of future cardiovascular events. Clinical factors that predict rapid progression of non-target lesions are unclear. The purpose of this study was to identify the clinical predictors of rapid progression and revascularization of coronary non-target lesions.
    UNASSIGNED: Consecutive patients with coronary heart disease who had undergone two serial coronary angiograms were enrolled. All coronary non-target lesions were identified and evaluated at both procedures. Multivariable Cox regression analysis was used to investigate the clinical risk factors associated with rapid progression or revascularization of coronary non-target lesions.
    UNASSIGNED: A total of 1255 patients and 1670 lesions were enrolled. In this cohort of patients, 239 (19%) had rapid progression and 186 (14.8%) underwent revascularization. At the lesion level, 251 (15.0%) had rapid progression and 194 (11.6%) underwent revascularization. The incidence of lesion revascularization and myocardial infarction was significantly higher in patients with rapid progression. In multivariable analyses, hypertension (hazard ratio [HR], 0.76; 95% confidence interval [95% CI], 0.58-1.00; p = 0.049), ST-segment elevation myocardial infarction (STEMI) (HR, 1.46; 95% CI, 1.03-2.07; p = 0.035), glycosylated hemoglobin (HR, 1.16; 95% CI, 1.01-1.33; p = 0.039) and lesion classification (B2/C versus A/B1) (HR, 1.73; 95% CI, 1.27-2.35; p = 0.001) were significant factors associated with rapid progression. The level of triglycerides (HR, 1.10; 95% CI, 1.00-1.20; p = 0.040) and lesion classification (B2/C versus A/B1) (HR, 1.53; 95% CI, 1.09-2.14; p = 0.014) were predictors of lesion revascularization.
    UNASSIGNED: Hypertension, STEMI, glycosylated hemoglobin and lesion classification may be used as predictors of rapid progression of coronary non-target lesions. The level of triglyceride and lesion classification may predict the revascularization of non-target lesions. In order to prevent future cardiovascular events, increased attention should be paid to patients with these factors.

    冠状动脉疾病(CAD)是左心室收缩功能障碍(LVSD)和心力衰竭(HF)的最常见原因。与单纯药物治疗相比,冠状动脉旁路移植术(CABG)的血运重建可降低这些患者的全因死亡率。尽管如此,CABG在少数HF患者中进行,部分原因是患者不愿意或无法接受大心脏手术,部分原因是由于手术风险高,医生不愿转诊手术。经皮冠状动脉介入治疗(PCI)是一种微创的血运重建方法,与CABG相比,有可能减少HF患者的围手术期并发症。PCI技术和技术的最新进展使PCI在高危HF患者中实现更完全的血运重建变得现实。尽管尚未进行PCI与药物治疗或CABG相比用于HF的随机对照临床试验(RCT)。在这次审查中,我们讨论了目前可用于HF的PCI的证据以及HF的血运重建程度与临床结局之间的关联.我们还回顾了PCI技术和技术的最新进展,这些技术可能改善HF的临床结果。最后,我们讨论了新出现的HF和大的血运重建的临床试验证据,持续存在的证据差距,应在未来的HF血运重建临床试验中解决。
    Coronary artery disease (CAD) is the most common cause of left ventricular systolic dysfunction (LVSD) and heart failure (HF). Revascularization with coronary artery bypass grafting (CABG) reduces all-cause mortality compared with medical therapy alone for these patients. Despite this, CABG is performed in a minority of patients with HF, partly due to patient unwillingness or inability to undergo major cardiac surgery and partly due to physician reluctance to refer for surgery due to high operative risk. Percutaneous coronary intervention (PCI) is a less-invasive method of revascularization that has the potential to reduce periprocedural complications compared with CABG in patients with HF. Recent advances in PCI technology and technique have made it realistic to achieve more complete revascularization with PCI in high-risk patients with HF, although no randomized controlled clinical trials (RCTs) of PCI in HF compared with either medical therapy or CABG have been performed. In this review, we discuss the currently available evidence for PCI in HF and the association between the extent of revascularization and clinical outcomes in HF. We also review recent advances in PCI technology and techniques with the potential to improve clinical outcomes in HF. Finally, we discuss emerging clinical trial evidence of revascularization in HF and the large, persistent evidence gaps that should be addressed with future clinical trials of revascularization in HF.

    缺血性心脏病是全球范围内最大的死亡原因,也是心力衰竭(HF)的最常见原因。由于人口老龄化和先前致命疾病如心肌梗塞的急性心脏护理的改善,HF的发病率和患病率正在增加。迫切需要改善缺血性收缩期HF患者预后的策略。HF患者的冠状动脉疾病检测系统利用不足,尽管有证据表明,在缺血性心力衰竭延期手术治疗研究中,冠状动脉旁路移植术(CABG)的死亡率比药物治疗降低,但仍有较少的患者进行血运重建。经皮冠状动脉介入治疗(PCI)是一种微创的冠状动脉血运重建方法;然而,最近的血运重建治疗缺血性心室功能障碍(REVIVED)-英国心血管介入学会(BCIS2)试验未能证明PCI与药物治疗相比对缺血性收缩性HF患者的获益.PCI和CABG对缺血性收缩性HF患者的疗效比较尚不清楚。尤其是在当代医学治疗的时代。在这次审查中,我们讨论了CABG在缺血性收缩性HF中的益处,其利用不足,和未满足的临床需求。我们还回顾了最近的将PCI与药物治疗进行比较的REVIVED-BCIS2试验,以及即将进行的PCI治疗缺血性收缩期HF的随机对照试验,以及尽管有正在进行的试验的预期数据,但仍将存在的持续证据空白.在当代血运重建方法和药物治疗的时代,仍有必要进行足够有力的随机对照试验,以确定PCI与CABG在缺血性收缩期HF中的比较临床有效性。以及在射血分数保留或左心室收缩功能障碍较严重的HF患者中进行冠状动脉血运重建的试验。
    Ischemic heart disease is the largest cause of death worldwide and the most common cause of heart failure (HF). The incidence and prevalence of HF are increasing owing to an aging population and improvements in the acute cardiac care of previously fatal conditions such as myocardial infarction. Strategies to improve outcomes in patients with ischemic systolic HF are urgently needed. There is systematic underutilization of testing for coronary artery disease in patients with HF, and revascularization is performed in an even smaller minority despite evidence for reduced mortality with coronary artery bypass grafting (CABG) over medical therapy in the Surgical Treatment for Ischemic Heart Failure Extension Study. Percutaneous coronary intervention (PCI) is a less-invasive approach to coronary revascularization; however, the recent Revascularization for Ischemic Ventricular Dysfunction (REVIVED)-British Cardiovascular Intervention Society (BCIS2) trial failed to demonstrate a benefit of PCI compared with that of medical therapy in patients with ischemic systolic HF. The comparative effectiveness of PCI and CABG for patients with ischemic systolic HF remains unknown, particularly in the era of contemporary medical therapy. In this review, we discuss the benefit of CABG in ischemic systolic HF, its underutilization, and the unmet clinical need. We also review the recent REVIVED-BCIS2 trial comparing PCI to medical therapy, as well as upcoming randomized controlled trials of PCI for ischemic systolic HF and persistent evidence gaps that will exist despite anticipated data from ongoing trials. There remains a need for an adequately powered randomized controlled trials to establish the comparative clinical effectiveness of PCI vs CABG in ischemic systolic HF in the era of contemporary revascularization approaches and medical therapy, as well as trials of coronary revascularization in patients with HF with preserved ejection fraction or less severe forms of left ventricular systolic dysfunction.

    经皮冠状动脉介入治疗(PCI)期间血管内超声(IVUS)或光学相干断层扫描(OCT)的使用得到了社会指南的认可。但是美国缺乏关于现实世界结果的数据。
    确定了2015年10月至2020年3月进行的住院患者PCI的Medicare索赔数据,并通过ICD-10-PCS代码捕获IVUS/OCT。对基线和手术特征进行三向倾向评分匹配(血管造影vsIVUSvsOCT)。主要不良心血管事件(MACE),死亡的复合,心肌梗死(MI),或重复血运重建,经过3年的评估,索引PCI后30天的空白窗口,以排除分阶段的程序。
    在502,821个PCI程序中,463,201(92%)仅由血管造影引导,IVUS或OCT用于37,908(7.5%)和1712(0.3%),分别。在倾向匹配之后,与血管造影相比,主要不良心血管事件的风险与IVUS相似(风险比[HR],0.97;95%CI,0.91-1.03;P=.285),但OCT较低(HR,0.85;95%CI,0.77-0.94;P=.001)。在临床相关亚组中观察到类似的趋势。与单纯血管造影相比,OCT显示MI或重复血运重建的风险较低(HR,0.86;95%CI,0.76-0.97;P=0.015),IVUS单独发生MI的风险较低(HR,0.90;95%CI,0.82-0.99;P=0.038)。
    在现实世界的美国队列中,在PCI期间不经常使用IVUS和OCT。与单纯血管造影相比,在首次PCI期间使用冠状动脉成像与3年内临床事件发生率较低相关.
    UNASSIGNED: Use of intravascular ultrasound (IVUS) or optical coherence tomography (OCT) during percutaneous coronary intervention (PCI) is endorsed by society guidelines, but US data on real-world outcomes are lacking.
    UNASSIGNED: Medicare claims data were identified for inpatient PCIs performed October 2015 to March 2020, with IVUS/OCT captured by ICD-10-PCS codes. Three-way propensity score matching (angio vs IVUS vs OCT) on baseline and procedural characteristics was performed. Major adverse cardiovascular events (MACE), a composite of death, myocardial infarction (MI), or repeat revascularization, was evaluated through 3 years, with a 30-day blanking window after index PCI to exclude staged procedures.
    UNASSIGNED: Of the 502,821 PCI procedures, 463,201 (92%) were guided by angiography alone, with IVUS or OCT used in 37,908 (7.5%) and 1712 (0.3%), respectively. After propensity matching, compared with angiography, the risk of major adverse cardiovascular event was similar for IVUS (hazard ratio [HR], 0.97; 95% CI, 0.91-1.03; P = .285) but lower for OCT (HR, 0.85; 95% CI, 0.77-0.94; P = .001). A similar trend was observed in clinically relevant subgroups. Compared with angiography alone, the risk of MI or repeat revascularization was lower with OCT (HR, 0.86; 95% CI, 0.76-0.97; P = .015), and the risk of MI alone was lower with IVUS (HR, 0.90; 95% CI, 0.82-0.99; P = .038).
    UNASSIGNED: In a real-world US cohort, IVUS and OCT were used infrequently during PCI. Compared with angiography alone, use of intracoronary imaging during index PCI was associated with lower rates of clinical events through 3 years.

    背景:糖尿病足是导致残疾和死亡的常见原因,合并症的足部感染通常会导致住院时间延长,医疗费用高,截肢率显着提高。大多数糖尿病足外伤并发下肢动脉病变,成为糖尿病足患者大截肢的独立危险因素。
    目的:建立血管内血运重建(ER)联合负压辅助封堵(VAC)治疗糖尿病足的疗效和安全性。
    方法:收集2018年4月至2022年4月苏州大学附属第二医院收治的40例糖尿病足患者的临床资料。糖尿病足病变根据瓦格纳分类进行分级,使用踝臂指数测试和下肢动脉计算机断层扫描血管造影评估下肢血流。连续皮下胰岛素输注泵用于实现血糖控制。经皮经腔球囊血管成形术(BA)或支架置入可促进下肢血运重建。通过蚕食清创术清洁伤口。VAC诱导伤口肉芽组织生长,创面修复采用植皮或皮瓣移植。
    结果:35例下肢血运重建,34例成功,血运重建成功率为97%。其中,6例股浅动脉BA后支架置入术,其中1例接受了动脉支架植入术。25例患者行膝下动脉血运重建,重建了39条动脉,其中7个用药物包衣的BA处理,其余32个用普通的旧BA处理。在32个伤口中进行VAC。行植皮24例,皮瓣移植2例。两名患者接受了大截肢手术,而17人有轻微截肢,占成功率的95%。
    结论:ER联合VAC治疗糖尿病足是一种安全有效的治疗方法,可显著提高保肢率。在ER后使用VAC简化并促进伤口修复。
    BACKGROUND: The diabetic foot is a common cause of disability and death, and comorbid foot infections usually lead to prolonged hospitalization, high healthcare costs, and a significant increase in amputation rates. And most diabetic foot trauma is complicated by lower extremity arteriopathy, which becomes an independent risk factor for major amputation in diabetic foot patients.
    OBJECTIVE: To establish the efficacy and safety of endovascular revascularization (ER) combined with vacuum-assisted closure (VAC) for the treatment of diabetic foot.
    METHODS: Clinical data were collected from 40 patients with diabetic foot admitted to the Second Affiliated Hospital of Soochow University from April 2018 to April 2022. Diabetic foot lesions were graded according to Wagner\'s classification, and blood flow to the lower extremity was evaluated using the ankle-brachial index test and computerized tomography angiography of the lower extremity arteries. Continuous subcutaneous insulin infusion pumps were used to achieve glycemic control. Lower limb revascularization was facilitated by percutaneous tran-sluminal balloon angioplasty (BA) or stenting. Wounds were cleaned by nibbling debridement. Wound granulation tissue growth was induced by VAC, and wound repair was performed by skin grafting or skin flap transplantation.
    RESULTS: Of the 35 cases treated with lower limb revascularization, 34 were successful with a revascularization success rate of 97%. Of these, 6 cases underwent stenting after BA of the superficial femoral artery, and 1 received popliteal artery stent implantation. In the 25 cases treated with infrapopliteal artery revascularization, 39 arteries were reconstructed, 7 of which were treated by drug-coated BA and the remaining 32 with plain old BA. VAC was performed in 32 wounds. Twenty-four cases of skin grafting and 2 cases of skin flap transplantation were performed. Two patients underwent major amputations, whereas 17 had minor amputations, accounting for a success limb salvage rate of 95%.
    CONCLUSIONS: ER in combination with VAC is a safe and effective treatment for diabetic foot that can significantly improve limb salvage rates. The use of VAC after ER simplifies and facilitates wound repair.

    左心室(LV)收缩功能障碍患者的冠状动脉血运重建后心脏性猝死(SCD)的风险尚未得到完全表征。本研究旨在评估此类患者血运重建后SCD的发生率和时间过程。还评估了血运重建后3个月内SCD的决定因素。
    一项射血分数降低(EF≤40%)患者的队列研究,进行了血运重建。据估计,SCD的发生率是由于其他原因导致死亡的竞争性风险。
    2317例患者入选。中位随访时间为3.5年,504例死亡中有162例(32.1%)是由于SCD。在血运重建后的前3个月,SCD的风险最高。发病率为0.37%/月。事件发生率降至0.12%/月,0.08%/月,0.09%/月,0.14%/月,3-6个月为0.19%/月,6-12个月,1-3年,3-5年,5-10年,分别。室性心动过速/室颤病史(危险比[HR],5.55;95%置信区间[CI],1.33-23.19;p=0.019)和三重血管疾病(HR,3.90;95%CI,1.38-11.05;p=0.010)与3个月内SCD的风险相关。然而,术前EF(以5%递增)不是预测性的(HR每增加5%,0.98;95%CI,0.62-1.55;p=0.935)。
    对于左心室功能障碍的患者,在血运重建后的前3个月,SCD的风险最高.需要进一步的风险分类和治疗策略。

    UNASSIGNED: The risk of sudden cardiac death (SCD) after coronary revascularization in patients with left ventricular (LV) systolic dysfunction has not been characterized completely. This study aims to evaluate the incidence and time course of SCD after revascularization in such patients. The determinants of SCD within 3 months after revascularization were also assessed.
    UNASSIGNED: A cohort study of patients with reduced ejection fraction (EF ≤ 40%), who underwent revascularization was performed. The incidence of SCD was estimated to account for the competing risk of deaths due to other causes.
    UNASSIGNED: 2317 patients were enrolled. With a median follow-up of 3.5 years, 162 (32.1%) of the 504 deaths were due to SCD. The risk of SCD was highest in the first 3 months after revascularization, with an incidence rate of 0.37%/month. The event rate decreased to 0.12%/month, 0.08%/month, 0.09%/month, 0.14%/month, and 0.19%/month at 3-6 months, 6-12 months, 1-3 years, 3-5 years, and 5-10 years, respectively. A history of ventricular tachycardia/ventricular fibrillation (hazard ratio [HR], 5.55; 95% confidence interval [CI], 1.33-23.19; p = 0.019) and triple vessel disease (HR, 3.90; 95% CI, 1.38-11.05; p = 0.010) were associated with the risk of SCD within 3 months. However, preoperative EF (in 5% increments) was not predictive (HR per 5% increase, 0.98; 95% CI, 0.62-1.55; p = 0.935).
    UNASSIGNED: For patients with LV dysfunction, the risk of SCD was the highest during the first 3 months after revascularization. Further risk classification and treatment strategy are warranted.

    大约一半的ST段抬高型心肌梗死(STEMI)患者患有多支血管冠状动脉疾病(MVD)。我们的目的是对有MVD的STEMI患者在指征血运重建期间的单阶段完全血运重建与延迟阶段完全血运重建进行定量比较。
    纳入所有评估STEMI和MVD患者的研究。主要终点是全因死亡的复合,心肌梗死和重复血运重建。次要终点是心血管死亡,急性肾损伤和试验定义了大出血。
    纳入了8项研究和2256例STEMI和MVD患者。研究组中主要复合终点的比率无明显差异(风险比0.95;95%CI0.71-1.27,p=0.74),而荟萃回归显示与药物洗脱支架(DES)的使用有显著的交互作用(系数-0.005;95%CI-0.01至-0.001;p=0.007).立即完全血运重建组的心血管(CV)死亡率更高(5.0%vs2.6%;风险比0.39;95%CI0.25-0.62;p<0.01)。
    我们的分析记录了相似的临床结果,单阶段立即完全血运重建和延迟阶段完全血运重建。次要分析表明,单阶段经皮冠状动脉介入治疗(PCI)可能会增加心血管死亡。虽然有关该主题的新随机试验正在进行中,血运重建可以通过急性临床环境进行个性化和指导,患者相关因素和工作流程物流。
    UNASSIGNED: About half of patients with ST-segment Elevation Myocardial Infarction (STEMI) have multivessel coronary artery disease (MVD). Our aim was to provide a quantitative comparison of single-stage complete revascularization during the index revascularization versus deferred staged complete revascularization in STEMI patients with MVD.
    UNASSIGNED: All studies evaluating patients with STEMI and MVD were included. The primary endpoint was a composite of all-cause death, myocardial infarction and repeat revascularization. Secondary endpoints were cardiovascular death, acute kidney injury and trial defined major bleeding.
    UNASSIGNED: Eight studies and 2256 patients with STEMI and MVD were included. No difference was evident in the rate of the primary composite endpoint among the study group (Risk Ratio 0.95; 95% CI 0.71-1.27, p = 0.74), while meta-regression showed a significant interaction with drug eluting stent (DES) use (Coefficient -0.005; 95% CI -0.01 to -0.001; p = 0.007). Higher rates of cardiovascular (CV) death were found in the immediate complete revascularization group (5.0% vs 2.6%; Risk Ratio 0.39; 95% CI 0.25-0.62; p < 0.01).
    UNASSIGNED: Our analysis documented similar clinical outcomes with either single-stage immediate complete revascularization and delayed staged complete revascularization. Secondary analyses suggest that an increase in cardiovascular death might be expected with single-stage percutaneous coronary intervention (PCI). While new randomized trials on the topic are ongoing, revascularization can be personalized and guided by the acute clinical setting, patients\'-related factors and workflow logistics.
