Objectives This study aimed to evaluate the efficacy and safety of AngioJet rheolytic thrombectomy with the adjunctive use of glycoprotein IIb/IIIa inhibitors (GPI) in the setting of ST-segment elevation myocardial infarction (STEMI). Methods We conducted a retrospective cohort study of 877 consecutive patients with STEMI. Propensity score matching (PSM) was employed to balance the baseline characteristics between the group receiving AngioJet rheolytic thrombectomy plus GPI (the AT + GPI group) and those receiving routine treatment (the RT group). The primary endpoint was major adverse cardiovascular and cerebrovascular events (MACCE) at 1 year. Safety endpoints comprised any bleeding and major bleeding events. Results Ninety-seven patients received AngioJet rheolytic thrombectomy and GPI. No significant differences were observed between the two groups regarding in-hospital mortality, reinfarction, stent thrombosis, stroke, or bleeding. After propensity-score matching, the cumulative incidence of MACCE at 1 year did not differ significantly between the AT + GPI group and the RT group (8.2% vs 9.3%; hazard ratio, 0.894; 95% CI, 0.345 to 2.318; p = 0.818). The incidence rates of all individual safety endpoints—including stroke and bleeding—showed no significant differences between the two groups. Conclusions In this observational cohort of STEMI patients, the strategy of combining AngioJet rheolytic thrombectomy with GPI was not associated with improved 1-year outcomes compared to routine treatment, though it did not increase bleeding or stroke risk.
Objectives This study aimed to identify clinical predictors of initial TIMI thrombus grade 5 (TG 5) and to evaluate its association with one‑year major adverse cardiovascular and cerebrovascular events (MACCE) in patients with ST‑segment elevation myocardial infarction (STEMI). Methods This single‑center retrospective cohort study enrolled 823 consecutive STEMI patients between October 2014 and April 2019, of whom 554 presented with initial TG 5 and 269 did not. Inverse probability of treatment weighting (IPTW) was applied to balance baseline covariates. Multivariable logistic regression was used to identify predictors of TG 5, and Cox proportional hazards models were fitted to assess the association between TG 5 and one‑year clinical outcomes. Results Delayed PCI (> 12 hours) (OR: 4.219; 95% CI: 2.915–6.098; P < 0.001), smoking history (OR: 1.606; 95% CI: 1.177–2.190; P = 0.003), and higher BMI (OR per 1 kg/m² increase: 1.070; 95% CI: 1.021–1.121; P = 0.004) were independently associated with initial TG 5. After IPTW adjustment, there were no significant differences between the TG 5 and non‑TG 5 groups in one‑year MACCE (adjusted OR: 0.782; 95% CI: 0.501–1.220; P = 0.278) or all‑cause mortality (adjusted OR: 0.797; 95% CI: 0.473–1.341; P = 0.393). Although the TG 5 group had a higher crude incidence of heart failure, the difference was attenuated after adjustment (P = 0.054). Rehospitalization for ischemic events was significantly lower in the TG 5 group after adjustment (adjusted OR: 0.395; 95% CI: 0.184–0.850; P = 0.018). Initial Killip class ≥ II (HR: 5.099; 95% CI: 3.509–7.408; P < 0.001), delayed PCI (HR: 1.697; 95% CI: 1.025–2.810; P = 0.040), and older age (HR: 1.038; 95% CI: 1.021–1.056; P < 0.001) were independently associated with MACCE, whereas TG 5 was not (HR: 0.765; 95% CI: 0.507–1.156; P = 0.204). Conclusions Delayed PCI, smoking, and higher BMI are strong independent predictors of initial TG 5 in STEMI patients. Although this angiographic phenotype reflects severe coronary occlusion, it is not independently associated with increased one‑year MACCE or all‑cause mortality after rigorous adjustment.
Background: Mechanical circulatory support may facilitate high-risk percutaneous coronary intervention (PCI). This study aimed to assess the feasibility, safety and effectiveness of high-risk PCI under the support of venoarterial extracorporeal membrane oxygenation (VA-ECMO) combined with intra-aortic balloon pump (IABP). Methods: We enrolled patients who received VA-ECMO plus IABP-assisted PCI procedures at our center from April 2012 to June 2018. Major adverse cardiac events (MACEs) included all-cause death, myocardial infarction, and target vessel revascularization. Results: A total of 10 patients were included, with a mean age of 71 years, EuroSCORE II of 19.9%, and SYNTAX score of 39.8. Procedural success was achieved in nine (90%) patients. The mean duration of ECMO support was 1.5 hours, and 2.6 stents were implanted per patient. Major complications included contrast-induced nephropathy needing hemodialysis in one (10%) patient, significant hemoglobin drop requiring blood transfusion in two (20%) patients, pulmonary infection in one (10%) patient, and local surgical incision infection in one (10%) patient. The accumulative mortality rates for the nine patients with procedural success were 0, 22.2%, and 44.4% at 1, 3, and 5 years follow-up, respectively. However, cardiac death occurred in only one (11.1%) patient. In addition, two patients received repeat PCI or coronary artery bypass grafting within two years following the index procedure. The overall incidence rates of MACEs were 11.1%, 44.4%, and 66.7% at 1, 3, and 5 years follow-up, respectively. Conclusions: VA-ECMO plus IABP-assisted high-risk PCI was feasible in patients with complex coronary disease, with a high procedural success rate and acceptable mid-term clinical outcomes.
The safety and effectiveness of remote guidance of percutaneous coronary interventions (PCI) have not been fully appraised in controlled studies. We hereby presented the results of a study on remote guidance (vs on-site guidance) of PCI to explore its feasibility, safety, and effectiveness. Patients were recruited from those who received PCI procedures from January 2018 to June 2019 in a secondary hospital (Jincheng, Shanxi, China), in collaboration with a tertiary medical center (Beijing, China) approximately 680 km away. According to the type of guidance during the procedure, the patients were assigned to two groups: the remote guidance group and the on-site guidance group. Remote guidance was assisted with an advanced commercial telemedicine system. Interventional strategies, procedural success rate, peri-procedural complications, procedural duration, radiation doses, and the amount of contrast medium were compared between the two groups. A total of 352 patients were included in this study, with a total of 411 PCI procedures and 446 target lesions. The baseline clinical characteristics, as well as the distribution and characteristics of coronary artery lesions, did not differ significantly between the two groups. No significant differences were noticed in procedural success rate, peri-procedural complications, procedural duration, radiation dose, and in-hospital major adverse cardiovascular events. However, the amount of contrast medium was slightly higher in the remote guidance group. The results of the present pilot study showed the feasibility of remotely guided PCI, with safety and effectiveness measures at acceptable levels comparable to the traditional on-site guidance. Randomized studies with long-term follow-up are warranted to further confirm our findings.
Objective This study aimed to evaluate predictors for adverse cardiovascular outcomes in patients with atrial fibrillation (AF) undergoing coronary stenting. Methods We retrospectively recruited consecutive patients with previously documented non-valvular AF who underwent coronary stenting between January 2010 and June 2015 in 12 hospitals of Beijing, China. Major adverse cardiac/cerebrovascular events (MACCE) were a composite of all-cause death, non-fatal myocardial infarction, repeat revascularization, and ischaemic stroke/systemic thromboembolism (IS/STE). Major bleeding referred to grade 2 or higher of Bleeding Academic Research Consortium criteria. Results A total of 2394 patients (men: 72.3% vs. women: 27.7%, median age: 67 years) were included. The CHA(2)DS(2)-VASc and HAS-BLED were 3.6 +/- 1.6 and 1.9 +/- 0.7, respectively. The median follow-up duration was 36.2 months. There were 230 (9.6%) deaths, 96 (4.0%) IS/STE, 426 (17.8%) MACCE, and 72 (3.0%) major bleeding. Multivariate Cox regression yielded predictive models for (1) all-cause death: diabetes, prior myocardial infarction, chronic kidney disease (CKD), ST-segment elevation myocardial infarction (STEMI) at presentation, heart failure, no use of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, and statins; (2) IS/STE: advanced age, prior history of ischaemic stroke and intracranial haemorrhage; (3) MACCE: prior history of myocardial infarction and ischaemic stroke, CKD, STEMI, heart failure, and no statin use; (4) major bleeding: prior major bleeding, prior myocardial infarction, CKD and use of oral anticoagulants. Conclusion Chinese patients with AF and coronary stenting had high mortality and incidence of MACCE. We compiled separate predictive models for all-cause death, IS/STE, MACCE, and major bleeding.
The aim of this study was to evaluate the effectiveness and safety of AngioJet rheolytic thrombectomy among patients with high thrombus burden. Routine manual thrombus aspiration in patients with ST-segment elevation myocardial infarction (STEMI) does not improve clinical outcomes and was associated with an increased rate of stroke. However, the safety of mechanical thrombus aspiration is still unknown. This was a retrospective, single-center study involving 621 patients with Thrombolysis In Myocardial Infarction thrombus grade 5. The primary outcome was the composite of major adverse cardiovascular events (MACE) within 12 months. The safety outcome was stroke within 1-year. Propensity matching score was calculated due to the significant baseline differences between the AngioJet rhelytic thrombectomy group and the routine treatment group. AngioJet rheolytic thrombectomy was performed in 117 patients. After propensity-score matching, there was no significant difference both in the incidence of MACE (11.1% vs 17.9%, hazard ratio, 1.641; 95% confidence interval [CI] 0.822 to 3.277, p = 0.161) and the incidences of stroke (1.7% vs 2.6%, hazard ratio 1.522; 95% confidence interval [CI] 0.254 to 9.107, p = 0.646) between two groups at 1-year follow-up. In patients with Thrombolysis In Myocardial Infarction thrombus grade 5, AngioJet rheolytic thrombectomy did not improve clinical outcomes at 1 year. However, AngioJet rheolytic thrombectomy did not increase the risk of stroke in patients with high thrombus burden.
Background/aim: Patients with atrial fibrillation (AF) and coronary stenting had a poor prognosis. This study aimed to assess the accuracy of CHA2 DS2 -VASc score for predicting and grading adverse clinical outcomes in this population. Materials and methods: We reviewed the clinical data of all patients with previously documented nonvalvular AF who underwent coronary stenting between January 2010 and June 2015 in 12 hospitals of Beijing, China. The study population was divided into three groups: 1) Low CHA2 DS2 -VASc score, ≦ 2 points, 2) Intermediate score, 3-4 points, and 3) High score, ≧ 5 points. Major adverse cardiac/cerebrovascular events (MACCE) were defined as a composite of all-cause death, nonfatal myocardial infarction, repeat revascularization and ischemic stroke/systemic thromboembolism (IS/SE). Results: A total of 2394 patients (men: 72.3% vs. women: 27.7%, median age: 67 years) were included, with the CHA2 DS2 -VASc score of 3.6 ± 1.6. The median follow-up duration was 36.2 months. All-cause mortality increased 3 folds from the low score (4.8%) to the high score group (15.8%). The high score group had more IS/SE (7.4%) and MACCE (26.3%). The CHA2 DS2 -VASc score ≧ 5 points was independently associated with all-cause death (hazard ratio [HR]: 2.303, 95% confidence interval [CI]: 1.492- 3.555), IS/SE (HR: 4.169, 95% CI: 2.216-7.845) and MACCE (HR: 1.468, 95% CI: 1.113-1.936) on multivariate Cox proportional hazards regression. The area under the receiver operating characteristic curve of the CHA2 DS2 -VASc score was 0.644 (95% CI: 0.624-0.663) for all-cause death, 0.647 (95% CI: 0.627-0.666) for IS/SE, and 0.592 (95% CI: 0.572-0.611) for MACCE. Conclusion: CHA2 DS2 -VASc score was a reliable prognostic indicator in patients with AF and coronary stenting.
BACKGROUND Venoarterial extracorporeal membrane oxygenation (VA-ECMO) offers hemodynamic support for patients undergoing high-risk percutaneous coronary interventions (PCIs). However, long-term outcomes associated with VA-ECMO have not previously been studied. AIM To explore long-term outcomes in high-risk cases undergoing PCI supported by VA-ECMO. METHODS In the present observational cohort study, 61 patients who received VA-ECMO-supported high-risk PCI between April 2012 and January 2020 at the Sixth Medical Center of Chinese People’s Liberation Army General Hospital were enrolled. The endpoint characteristics such as all-cause mortality, repeated cardiovascular diseases, and cardiac death were examined. RESULTS Among 61 patients, three failed stent implantation due to chronic total occlusions with severely calcified lesions. One patient showed VA-ECMO intolerance because of high left ventricular afterload. PCI was successfully performed in 57 patients (93.4%). The in-hospital mortality was 23.0%, and the overall survival was 45.9%, with a median follow-up period of 38.6 (8.6-62.1) mo. CONCLUSION VA-ECMO can be used as a support in patients undergoing high-risk PCI as it is associated with favorable long-term patient survival.

BACKGROUND Venous thromboembolism is a common vascular syndrome presenting as deep vein thrombosis and/or pulmonary embolism. Thrombus has the possibility of migrating into the left circulation via patent foramen ovale in certain extreme circumstances. Thrombus straddling a patent foramen ovale is a direct evidence of this scenario. However, the confirmed cases of thrombus in transit are still rare. CASE SUMMARY A 32-year-old man suffered from recurrent syncope and intermittent dyspnea for 1 wk. Transthoracic echocardiography confirmed a thrombus straddling the patent foramen ovale, and thrombi were also found in the bilateral pulmonary artery by computed tomography. The man underwent inferior vena cava filter placement and thrombolysis with alteplase. Echocardiography showed the absence of thrombi in both the right atrium and left atrium 2 d after hospitalization. The man was discharged to home on warfarin without any complications 2 wk later. CONCLUSION Scrutinizing intracardiac thrombi provides measurable value in pulmonary embolism as closure of patent foramen ovale may be considered in certain patients. Early intervention plays a critical role in thrombus straddling a patent foramen ovale. A sedentary lifestyle may predispose young adults to thromboembolism, even if there are no other risk factors.
Case 1 In June 2010, a 7-month-old boy was admitted because of heart failure. He experienced feeding intolerance since birth and was diagnosed with dilated cardiomyopathy at his local hospital. At admission, a grade 3/6 systolic murmur was heard at the cardiac apex. His electrocardiogram (ECG) showed deep and wide Q waves in leads I, aVL and V3–V5 (Fig. 1), raising suspicion of anomalous left coronary artery from the pulmonary artery (ALCAPA). Echocardiography demonstrated markedly dilated left ventricle (LV) and atrium with preserved LV ejection fraction and severe mitral regurgitation. Color Doppler imaging showed the

Background: The long-term mortality, thrombotic risk and bleeding complications of very old patients (>= 80 years) with atrial fibrillation (AF) and coronary stenting were less studied.Methods: We enrolled 1504 patients >= 65 years with nonvalvular AF undergoing coronary stenting between January 2010 and June 2015 from 12 hospitals in Beijing, China.Results: 164 patients (10.9%) had ages >= 80 years. Very old patients had higher prevalence of cardiac dysfunction, renal dysfunction (RD, creatinine clearance < 60 ml/min), anemia and acute ST segment elevation myocardial infarction (STEMI) than younger patients. The mean follow-up duration was 39.0 +/- 18.7 months. Complete follow-up data was obtained for 94.3% of the whole cohort. Very old patients had higher mortality (22.8% vs. 10.6%, p < 0.001), more major adverse cardiac/cerebro-vascular events (MACCE, 33.6% vs. 18.5%, p < 0.001), and major bleeding events (MB) (5.4% vs. 2.8%, p = 0.150) than younger controls. For very old patients, multivariate Cox regression identified cardiac dysfunction (HR: 2.564, 95% CI: 1.279-5.139, p = 0.008), RD (HR: 4.001, 95% CI: 1.518-10.546, p = 0.005) and STEMI (HR: 2.529, 95% CI: 1.275-5.013, p = 0.008) as independent predictors for all-cause death; cardiac dysfunction (HR: 2.590, 95% CI: 1.470-4.565, p = 0.001) and RD (HR: 4.204, 95% CI: 1.865-9.476, p = 0.001) as independent predictors for MACCE; cardiac dysfunction (HR: 2.417, 95% CI: 1.399-4.176, p = 0.002), RD (HR: 4.278, 95% CI: 1.997-9.164, p < 0.001) and STEMI (HR: 1.767, 95% CI: 1.008-3.097, p = 0.047) as independent predictors for the composite endpoint of MACCE and MB.Conclusion: Very old patients with AF and coronary stenting had a poor long-term prognosis, with cardiac dysfunction and RD as independent risk factors.

BACKGROUND:To analyze the cardio-protective effects of ticagrelor in patients with acute coronary syndrome with S-T segment elevation.METHODS:The sample was 200 patients who had been diagnosed with acute coronary syndrome accompanied by diabetes Mellitus type II. Only patients having ST segment elevation before the treatment were included. Then, the subjects were further randomly divided into an observation group and a control group. The control group of 100 patients received clopidogrel; the observation group of 100 patients of ticagrelor. The serous creatine kinase CK-MB, functional cardiac indexes of left ventricular end diastolic diameter (LVDD), cardiac troponin I, ventricular ejection fraction, and relevant major adverse cardiovascular events (MACE) were compared between the two groups.RESULTS:One month after a percutaneous coronary intervention (PCI) the observation group showed better results against angina, stent thrombosis, and all-cause mortality compared with those of the control subjects. Six months after treatment, both groups suffered adverse reactions. The number of patients who suffered adverse reactions in respiratory tract in the observation group was higher than in the control group. The inhibition of platelet aggregation IPA of ticagrelor was found to be significantly higher than clopidogrel, having a significant p value.CONCLUSION:Ticagrelor can effectively protect myocardial function for patients with ST-segment elevation acute coronary syndrome accompanied by diabetes and can reduce the incidence of adverse reactions..

Objective To assess the feasibility,safety and efficacy of primary PCI in elderly patients with AMI.Methods Three hundred and sixty-four AMI patients were divided into ≥75 years old group (n=90) and <75 years old group (n=274).The successful operation rate,preoperative complication rate,mortality and incidence of major adverse cardiovascular events (MACE) were recorded during their hospital stay time.Results The successful operation rate was 94.4%,the postoperative TIMI 3 blood flow rate was 87.8%,and the preoperative complication rate was 10.0 % in ≥75 years old group.The mortality and incidence of MACE were significantly higher in ≥75 years old group than in<75 years old group during the hospital stay time (12.2% vs 2.9%,P =0.001;16.7 % vs 5.1%,P =0.000).Conclusion Transradial primary PCI is a safe,feasible and effective therapy for ≥75 years old AMI patients.
Objective To review the effect of ivabradine on heart rate (HR) controlling during computerized tomography (CT) of coronary artery by applying Meta-analysis. Methods The databases of PubMed, CENTRAL, EMbase, CBM, CNKI and WanFang Database were retrieved, and eligible randomized controlled trials (RCT) were given Meta-analysis after quality reviewing and data extracting. Results There were 8 RCT included involved 1298 cases, and 765 in intervention group and 533 in control group. The results showed that HR was significantly decreased in intervention group (MD=-8.92, 95%CI: -10.24~ -7.59, P<0.0001) compared with control group, and the effect of decreasing HR was more significant in intervention group than that in β-receptor blocker group (MD=-5.16, 95%CI: -8.54~ -1.78, P=0.003). There was no significant difference between 10 mg ivabradine and 15 mg ivabradine in decreasing HR (MD=4.87, 95%CI: -5.81~15.55, P=0.37). The systolic blood pressure was slightly elevated in intervention group compared with that in control group, and diastolic blood pressure was slightly elevated in intervention group compared with β-receptor blocker group. The percentage of achieving target HR was higher in intervention group than that in blank control group (MD=3.78, 95%CI: 2.79~5.13, P<0.0001), and the difference was not significant between intervention group and β-receptor blocker group. The adverse reactions were mainly transient nodal bradyarrhythmia, photopsy, blurred vision and photopsia. There were no severe life-threatening adverse reactions observed. Conclusion During CT of coronary artery, ivabradine (10 mg~15 mg) can be used to replace β-receptor blocker and/or non-dihydropyridines calcium channel blocker for controlling HR.
