ABSTRACT

BACKGROUND@#The Chinese appropriate use criteria (AUC) for coronary revascularization was released in 2016 to improve the use of coronary revascularization. This study aimed to evaluate the association between the appropriateness of coronary revascularization based on the Chinese AUC and 1-year outcomes in stable coronary artery disease (CAD) patients.@*METHODS@#We conducted a prospective, multi-center cohort study of stable CAD patients with coronary lesion stenosis ≥50%. After the classification of appropriateness based on Chinese AUC, patients were categorized into the coronary revascularization group or the medical therapy group based on treatment received. The primary outcome was a composite of death, myocardial infarction, stroke, repeated revascularization, and ischemic symptoms with hospital admission.@*RESULTS@#From August 2016 to August 2017, 6085 patients were consecutively enrolled. Coronary revascularization was associated with a lower adjusted hazard of 1-year major adverse cardiovascular and cerebrovascular events (MACCEs; hazard ratio [HR]: 0.62; 95% confidence interval [CI]: 0.45-0.86; P = 0.004) than medical therapy in patients with appropriate indications (n = 1617). No significant benefit in 1-year MACCEs was found after revascularization compared to after medical therapy in patients with uncertain indications (n = 2658, HR: 0.81; 95% CI: 0.52-1.25; P = 0.338) and inappropriate indications (n = 1810, HR: 0.80; 95% CI: 0.51-1.23; P = 0.308).@*CONCLUSIONS@#In patients with appropriate indications according to Chinese AUC, coronary revascularization was associated with significantly lower risk of MACCEs at 1 year. No benefit was found in coronary revascularization in patients with inappropriate indications. Our findings provide evidence for using Chinese AUC to guide clinical decision-making.@*CLINICAL TRIAL REGISTRATION@#NCT02880605. https://www.clinicaltrials.gov.

ABSTRACT

BACKGROUND@#Coronary atherosclerotic plaque could go through rapid progression and induce adverse cardiac events. This study aimed to evaluate the impacts of smoking status on clinical outcomes of coronary non-target lesions.@*METHODS@#Consecutive patients with coronary heart disease who underwent two serial coronary angiographies were included. All coronary non-target lesions were recorded at first coronary angiography and analyzed using quantitative coronary angiography at both procedures. Patients were grouped into non-smokers, quitters, and smokers according to their smoking status. Clinical outcomes including rapid lesion progression, lesion re-vascularization, and myocardial infarction were recorded at second coronary angiography. Multivariable Cox regression analysis was used to investigate the association between smoking status and clinical outcomes.@*RESULTS@#A total of 1255 patients and 1670 lesions were included. Smokers were younger and more likely to be male compared with non-smokers. Increase in percent diameter stenosis was significantly lower (2.7 [0.6, 7.1] % vs. 3.5 [0.9, 8.9]%) and 3.4 [1.1, 7.7]%, P = 0.020) in quitters than those in smokers and non-smokers. Quitters tended to have a decreased incidence of rapid lesions progression (15.8% [76/482] vs. 21.6% [74/342] and 20.6% [89/431], P = 0.062), lesion re-vascularization (13.1% [63/482] vs. 15.5% [53/432] and 15.5% [67/431], P = 0.448), lesion-related myocardial infarction (0.8% [4/482] vs. 2.6% [9/342] and 1.4% [6/431], P = 0.110) and all-cause myocardial infarction (1.9% [9/482] vs. 4.1% [14/342] and 2.3% [10/431], P = 0.128) compared with smokers and non-smokers. In multivariable analysis, smoking status was not an independent predictor for rapid lesion progression, lesion re-vascularization, and lesion-related myocardial infarction except that a higher risk of all-cause myocardial infarction was observed in smokers than non-smokers (hazards ratio: 3.00, 95% confidence interval: 1.04-8.62, P = 0.042).@*CONCLUSION@#Smoking cessation mitigates the increase in percent diameter stenosis of coronary non-target lesions, meanwhile, smokers are associated with increased risk for all-cause myocardial infarction compared with non-smokers.

ABSTRACT

BACKGROUND@#The mechanism and characteristics of early and late drug-eluting stent in-stent restenosis (DES-ISR) have not been fully clarified. Whether there are different outcomes among those patients being irrespective of their repeated treatments remain a knowledge gap.@*METHODS@#A total of 250 patients who underwent initial stent implantation in our hospital, and then were readmitted to receive treatment for the reason of recurrent significant DES-ISR in 2016 were involved. The patients were categorized as early ISR (<12 months; E-ISR; n = 32) and late ISR (≥12 months; L-ISR; n = 218). Associations between patient characteristics and clinical performance, as well as clinical outcomes after a repeated percutaneous coronary intervention (PCI) were evaluated. Primary composite endpoint of major adverse cardiac events (MACEs) included cardiac death, non-fatal myocardial infarction (MI), or target lesion revascularization (TLR).@*RESULTS@#Most baseline characteristics are similar in both groups, except for the period of ISR, initial pre-procedure thrombolysis in myocardial infarction, and some serum biochemical indicators. The incidence of MACE (37.5% vs. 5.5%; P < 0.001) and TLR (37.5% vs. 5.0%; P < 0.001) is higher in the E-ISR group. After multivariate analysis, E-ISR (odds ratio [OR], 13.267; [95% CI 4.984-35.311]; P < 0.001) and left ventricular systolic dysfunction (odds ratio [OR], 6.317; [95% CI 1.145-34.843]; P = 0.034) are the independent predictors for MACE among DES-ISR patients in the mid-term follow-up of 12 months.@*CONCLUSIONS@#Early ISR and left ventricular systolic dysfunction are associated with MACE during the mid-term follow-up period for DES-ISR patients. The results may benefit the risk stratification and secondary prevention for DES-ISR patients in clinical practice.

ABSTRACT

Objective@#To analyze factors associated with unplanned revascularization (UR) risk in patients with coronary artery disease (CAD) who underwent percutaneous coronary intervention (PCI).@*Methods@#A total of 10,640 cases with CAD who underwent PCI were analyzed. Multivariate COX regressions and competing risk regressions were applied.@*Results@#The patients who underwent UR following PCI in 30 days, 1, and 2 years accounted for 0.3%, 6.5%, and 8.7%, respectively. After multivariate adjustment, the number of target lesions [hazard ratio ( ) = 2.320; 95% confidence interval ( ): 1.643-3.277; < 0.001], time of procedure ( = 1.006; 95% : 1.001-1.010; = 0.014), body mass index ( = 1.104; 95% : 1.006-1.210; = 0.036), incomplete revascularization (ICR) ( = 2.476; 95% : 1.030-5.952; = 0.043), and age ( 1.037; 95% : 1.000-1.075; = 0.048) were determined as independent risk factors of 30-day UR. Factors, including low-molecular-weight heparin or fondaparinux ( = 0.618; 95% : 0.531-0.719; < 0.001), second-generation durable polymer drug-eluting stent ( 0.713; 95% : 0.624-0.814; < 0.001), left anterior descending artery involvement ( = 0.654; 95% : 0.530-0.807; < 0.001), and age ( = 0.992; 95% : 0.985-0.998; = 0.014), were independently associated with decreased two-year UR risk. While, Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery score ( = 1.024; 95% : 1.014-1.033; < 0.001) and ICR ( = 1.549; 95% : 1.290-1.860; < 0.001) were negatively associated with two-year UR risk.@*Conclusion@#Specific factors were positively or negatively associated with short- and medium-long-term UR following PCI.

ABSTRACT

BACKGROUND@#It is currently unclear if fibrinogen is a risk factor for adverse events in patients receiving percutaneous coronary intervention (PCI) or merely serves as a marker of pre-existing comorbidities and other causal factors. We therefore investigated the association between fibrinogen levels and 2-year all-cause mortality, and compared the additional predictive value of adding fibrinogen to a basic model including traditional risk factors in patients receiving contemporary PCI.@*METHODS@#A total of 6293 patients undergoing PCI with measured baseline fibrinogen levels were enrolled from January to December 2013 in Fuwai Hospital. Patients were divided into three groups according to tertiles of baseline fibrinogen levels: low fibrinogen, <2.98 g/L; medium fibrinogen, 2.98 to 3.58 g/L; and high fibrinogen, ≥3.58 g/L. Independent predictors of 2-year clinical outcomes were determined by multivariate Cox proportional hazards regression modeling. The increased discriminative value of fibrinogen for predicting all-cause mortality was assessed using the C-statistic and integrated discrimination improvement (IDI).@*RESULTS@#The 2-year all-cause mortality rate was 1.2%. It was significantly higher in the high fibrinogen compared with the low and medium fibrinogen groups according to Kaplan-Meier analyses (1.7% vs. 0.9% and 1.7% vs. 1.0%, respectively; log-rank, P = 0.022). Fibrinogen was significantly associated with all-cause mortality according to multivariate Cox regression (hazard ratio 1.339, 95% confidence interval: 1.109-1.763, P = 0.005), together with traditional risk factors including age, sex, diabetes mellitus, left ventricular ejection fraction, creatinine clearance, and low-density lipoprotein cholesterol. The area under the curve for all-cause mortality in the basic model including traditional risk factors was 0.776, and this value increased to 0.787 when fibrinogen was added to the model (IDI = 0.003, Z = 0.140, P = 0.889).@*CONCLUSIONS@#Fibrinogen is associated with 2-year all-cause mortality in patients receiving PCI, but provides no additional information over a model including traditional risk factors.

ABSTRACT

Background@#It remains undetermined whether second-generation drug-eluting stents (G2-DESs) outperform first-generation DESs (G1-DESs) in patients with acute coronary syndrome (ACS). We aimed to compare the efficacy and safety of G1-DES and G2-DES in ACS patients in a high-volume cardiovascular center.@*Methods@#In 2013, 10,724 consecutive patients underwent percutaneous coronary intervention in our institution. We included 4037 patients with ACS who underwent exclusively G1-DES or G2-DES implantation (n = 364 and n = 3673, respectively). We used propensity score matching to minimize the imbalance between the G1-DES and G2-DES groups and followed patients for 2 years. The efficacy endpoints were major adverse cardiac events (MACEs) and its components including target vessel-related myocardial infarction (TV-MI), target vessel revascularization/target lesion revascularization (TVR/TLR), and cardiac death. The safety endpoint was stent thrombosis. Continuous variables were compared by Mann-Whitney U-test, and categorical variables were compared using Pearson's Chi-square or Fisher's exact test. Kaplan-Meier curves were constructed to compare the event-free survival rates, and multivariate Cox proportional hazards regression analysis was used to assess whether stent type was an independent risk factor for the efficacy and safety endpoints.@*Results@#At the 2-year follow-up, the results for MACE and it components, as well as stent thrombosis, were similar for G1-DES and G2-DES (MACE, 5.2% vs. 4.3%, χ = 0.514, P = 0.474; TV-MI, 0.8% vs. 0.4%, P = 0.407; TVR, 4.9% vs. 3.7%, χ = 0.939, P = 0.333; TLR, 3.8% vs. 2.5%, χ = 1.610, P = 0.205; cardiac death, 0.3% vs. 0.5%, P = 0.670; and stent thrombosis, 0.5% vs. 0.4%, P > 0.999). Kaplan-Meier analysis indicated similar event-free survival rates between G1-DES and G2-DES after propensity score matching (all: log-rank P > 0.05). Multivariate analysis demonstrated that stent type was not an independent risk factor for the efficacy and safety endpoints (MACE, hazard ratio [HR] = 0.805, 95% confidence interval [CI]: 0.455-1.424, P = 0.456; TV-MI, HR = 0.500, 95% CI: 0.101-2.475, P = 0.395; TVR, HR = 0.732, 95% CI: 0.403-1.330, P = 0.306; TLR, HR = 0.629, 95% CI: 0.313-1.264, P = 0.193; cardiac death, HR = 1.991, 95% CI: 0.223-17.814, P = 0.538; and stent thrombosis, HR = 0.746, 95% CI: 0.125-4.467, P = 0.749).@*Conclusion@#G1-DES and G2-DES have similar efficacy and safety profiles in ACS patients at the 2-year follow-up.

ABSTRACT

Background@#The patterns of nonadherence to antiplatelet regimen in stented patients (PARIS) thrombotic risk score are a novel score for predicting the risk of coronary thrombotic events (CTEs) after percutaneous coronary intervention (PCI) with drug-eluting stents. However, the prognostic value of this score has not been fully evaluated in non-Euro-American PCI populations.@*Methods@#We performed a prospective, observational study of 10,724 patients who underwent PCI in Fuwai hospital, China and evaluated the PARIS thrombotic risk score's predictive value of CTEs in the PCI population. The area under the receiver operating characteristic curve (AUROC) was used to assess the predictive value of the PARIS score for CTE.@*Results@#Among 9782 patients without in-hospital events, a total of 95 CTEs occurred during the 2-year follow-up. The PARIS score was significantly higher in patients with CTEs (3.38 ± 2.04) compared with patients without events (2.53 ± 1.70, P < 0.001). According to the risk stratification of the PARIS thrombotic score, the risk of CTEs in the high-risk group was 3.14 times higher than that in the low-risk group (hazard ratio [HR], 3.14; 95% confidence interval [CI], 1.92-5.13; P < 0.001). However, the risk of CTEs in the intermediate-risk and low-risk groups was not significant (HR, 1.39; 95% CI, [0.86-2.24]; P = 0.184). The PARIS score showed prognostic value in evaluating CTEs in the overall population (AUROC, 0.621; 95% CI, 0.561-0.681), the acute coronary syndrome (ACS) population (AUROC, 0.617; 95% CI, 0.534-0.700; P = 0.003), and the non-ACS population (AUROC, 0.647; 95% CI, 0.558-0.736; P = 0.001).@*Conclusions@#In a real-world Chinese population, the PARIS thrombotic risk score shows a modest prognostic value for CTEs in patients after PCI. This score also has a predictive value for CTEs in the ACS and non-ACS subgroup populations.

ABSTRACT

Background@#Mounts of studies have shown that low estimated glomerular filtration rate (eGFR) is associated with increased risk of adverse outcomes in patients with coronary artery disease. However, high level of eGFR was less reported. In the study, we aimed to explore the relationship between the baseline eGFR, especially the high level, and contrast-induced acute kidney injury (CI-AKI) in a Chinese population who underwent an emergency percutaneous coronary intervention (PCI).@*Methods@#Patients who underwent an emergency PCI from 2013 to 2015 were enrolled and divided into five groups as eGFR decreasing. Baseline characteristics were collected and analyzed. The rates of CI-AKI and the composite endpoint (including nonfatal myocardial infarction, revascularization, stroke, and all-cause death) at 6- and 12-month follow-up were compared. Logistic analysis for CI-AKI was performed.@*Results@#A total of 1061 patients were included and the overall CI-AKI rate was 22.7% (241/1061). The separate rates were 77.8% (7/9) in Group 1 (eGFR ≥120 ml·min·1.73 m), 26.0% (118/454) in Group 2 (120 ml·min·1.73 m> eGFR ≥90 ml·min·1.73m), 18.3% (86/469) in Group 3 (90 ml·min·1.73 m> eGFR ≥60 ml·min·1.73 m), 21.8% (26/119) in Group 4 (60 ml·min·1.73 m> eGFR ≥30 ml·min·1.73 m), and 40.0% (4/10) in Group 5 (eGFR <30 ml·min·1.73 m), with statistical significance (χ = 25.19, P < 0.001). The rates of CI-AKI in five groups were 77.8%, 26.0%, 18.3%, 21.8%, and 40.0%, respectively, showing a U-typed curve as eGFR decreasing (the higher the level of eGFR, the higher the CI-AKI occurrence in case of eGFR ≥60 ml·min·1.73 m). The composite endpoint rates in five groups were 0, 0.9%, 2.1%, 6.7%, and 0 at 6-month follow-up, respectively, and 0, 3.3%, 3.4%, 16.0%, and 30.0% at 12-month follow-up, respectively, both with significant differences (χ = 16.26, P = 0.009 at 6-month follow-up, and χ = 49.05, P < 0.001 at 12-month follow-up). The logistic analysis confirmed that eGFR was one of independent risk factors of CI-AKI in emergency PCI patients.@*Conclusions@#High level of eGFR might be associated with increased risk of CI-AKI in patients with emergency PCI, implying for future studies and risk stratification in clinical practice.

ABSTRACT

BACKGROUND@#There is scanty evidence concerning the ability of Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes with Early Implementation of the ACC/AHA Guidelines (CRUSADE) and Acute Catheterization and Urgent Intervention Triage Strategy and Harmonizing Outcomes with Revascularization and Stents in Acute Myocardial Infarction (ACUITY-HORIZONS) scores to predict out-of-hospital bleeding risk after percutaneous coronary interventions (PCIs) with drug-eluting stents (DES) in patients receiving dual antiplatelet therapy. We aimed to assess and compare the long-term prognostic value of these scores regarding out-of-hospital bleeding risk in such patients.@*METHODS@#We performed a prospective observational study of 10,724 patients undergoing PCI between January and December 2013 in Fuwai Hospital, China. All patients were followed up for 2 years and evaluated through the Fuwai Hospital Follow-up Center. Major bleeding was defined as Types 2, 3, and 5 according to Bleeding Academic Research Consortium Definition criteria.@*RESULTS@#During a 2-year follow-up, 245 of 9782 patients (2.5%) had major bleeding (MB). CRUSADE (21.00 [12.00, 29.75] vs. 18.00 [11.00, 26.00], P 0.05). The value of CRUSADE and ACUITY-HORIZONS scores did not differ significantly (P > 0.05) in the whole cohort, ACS subgroup, or non-ACS subgroup.@*CONCLUSIONS@#CRUSADE and ACUITY-HORIZONS scores showed statistically significant but relatively limited long-term prognostic value for out-of-hospital MB after PCI with DES in a cohort of Chinese patients. The value of CRUSADE and ACUITY-HORIZONS scores did not differ significantly (P > 0.05) in the whole cohort, ACS subgroup, or non-ACS subgroup.

ABSTRACT

OBJECTIVE@#The predictive value of N-terminal pro-brain natriuretic peptide (NT-proBNP) in patients with stable coronary artery disease (SCAD) in the drug-eluting stent era is not yet clear. We aimed to evaluate the prognostic value of NT-proBNP in SCAD patients after percutaneous coronary intervention (PCI).@*METHODS@#We examined 4,293 consecutive SCAD patients who underwent PCI between January 2013 and December 2013 in Fuwai Hospital, China. The primary endpoint was all-cause death. NT-proBNP levels were measured before PCI using Elisa kits (Biomedica, Austria). The indication for PCI was based on the degree of coronary stenosis and evidence of ischemia.@*RESULTS@#Among 3,187 SCAD patients with NT-proBNP data, after a 2-year follow-up, NT-proBNP levels were predictive for all-cause death in the SCAD population [area under the receiver operating characteristic curve, 0.768; 95% confidence interval (CI), 0.687-0.849; P < 0.001]. At the optimum cutoff point of 732 pg/mL, the sensitivity and specificity of death was 75.0% and 72.3%, respectively. In a multivariable Cox regression model, the death hazard ratio was 6.43 (95% CI, 2.99-13.82; P < 0.001) for patients with NT-proBNP levels ⪖ 732 pg/mL, compared with < 732 pg/mL.@*CONCLUSION@#NT-proBNP is a strong predictor of 2-year death with SCAD after PCI in the drug-eluting stent era.

ABSTRACT

<p><b>Background</b>Residual SYNTAX score (rSS) and its derived indexes including SYNTAX revascularization index (SRI) and clinical rSS had been developed to quantify and describe the extent of incomplete revascularization. This study was conducted to explore the utility of the three scores among real-world patients after percutaneous coronary intervention (PCI).</p><p><b>Methods</b>From January 2013 to December 2013, patients underwent PCI treatment at Fuwai Hospital were included. The primary endpoints were all-cause death and major adverse cardiovascular and cerebrovascular events. The secondary endpoints were myocardial infarction, revascularization, stroke, and stent thrombosis. Kaplan-Meier methodology was used to determine the outcomes. Cox multivariable regression was to test the associations between scores and all-cause mortality.</p><p><b>Results</b>A total of 10,344 patients were finally analyzed in this study. Kaplan-Meier survival analysis indicated that greater residual coronary lesions quantified by rSS and its derived indexes were associated with increased risk of adverse cardiovascular events. However, after multivariate analysis, only clinical rSS was an independent predictor of 2-year all-cause death (hazard ratio: 1.02, 95% confidence interval: 1.01-1.03, P < 0.01). By receiver operating characteristic (ROC) curve analysis, clinical rSS had superior predictability of 2-year all-cause death than rSS and SRI (area under ROC curve [AUC]: 0.59 vs. 0.56 vs. 0.56, all P < 0.01), whereas rSS was superior in predicting repeat revascularization than clinical rSS and SRI (AUC: 0.62 vs. 0.61 vs. 0.61; all P < 0.01). When comparing the predictive capability of rSS ≥8 with SRI <70%, their predictabilities were not significantly different.</p><p><b>Conclusions</b>This study indicates that all three indexes (rSS, clinical rSS, and SRI) are able to risk-stratify patients and predict 2-year outcomes after PCI. However, their prognostic capabilities are different.</p>

ABSTRACT

<p><b>Background</b>The Patterns of Non-Adherence to Anti-Platelet Regimens in Stented Patients (PARIS) bleeding score is a novel score for predicting the out-of-hospital bleeding risk after percutaneous coronary intervention (PCI). However, whether this score has the same value in non-European and American populations is unclear. This study aimed to assess the PARIS bleeding score's predictive value of bleeding in patients after PCI in the Chinese population.</p><p><b>Methods</b>We performed a prospective, observational study of 10,724 patients who underwent PCI from January to December 2013, in Fuwai Hospital, China. We defined the primary end point as major bleeding (MB) according to Bleeding Academic Research Consortium definition criteria including Type 2, 3, or 5. The predictive value of the PARIS bleeding score was assessed with the area under the receiver operating characteristic (AUROC) curve.</p><p><b>Results</b>Of 9782 patients, 245 (2.50%) MB events occurred during the 2 years of follow-up. The PARIS bleeding score was significantly higher in the MB group than that of non-MB group (4.00 [3.00, 5.00] vs. 3.00 [2.00, 5.00], Z = 3.71, P < 0.001). According to risk stratification of the PARIS bleeding score, the bleeding risk in the intermediate- and high-risk groups was 1.50 times (hazard ratio [HR]: 1.50; 95% confidence interval [CI]: 1.160-1.950; P = 0.002) and 2.27 times higher (HR: 2.27; 95% CI: 1.320-3.900; P = 0.003) than that in the low-risk group.

ABSTRACT

Objectives: To investigate the characteristics of coronary lesions and evaluate the prognosis post-percutaneous coronary intervention(PCI)in smokers with coronary heart disease. Methods: The data were derived from PANDA III, which was a perspective, multi-center, "all-comer", randomized controlled trial. Between Dec. 2013 and Aug. 2014, 2 348 patients from 46 centers were enrolled. Mean age was (61.2 ±10.6) years old, 1 658 patients (70.6%) were male. All the patients underwent PCI and biodegradable polymer drug eluting stents were implanted as indicated. Patients were divided into non-smoking group, quitter group and smoking-group based on the basis of smoking status at baseline. Primary endpoint was major adverse cardiac events (MACE), including all-cause mortality, myocardial infarction and repeated revascularization. Secondary endpoint were stent thrombosis and target lesion failure (TLF), including cardiac death, target vessel myocardial infarction and ischemia driven target lesion revascularization. Results: Smokers and quitters were more often males. Compared with non-smoking group and quitter group, patients in smoking group were significantly younger (P<0.0001), proportion of hypertension (P=0.0002), diabetes mellitus (P=0.0052) and previous PCI history (P<0.0001) was significantly lower. The incidence of acute myocardial infarction in the smoking group was as high as 41.3% (363/879), which was significantly higher than that of the quitter group and non-smoking group (P<0.0001). A total of 1 130 (96.7%), 286 (95.3%) and 846 (96.2%) patients in the non-smoking group, quitter group and smoking-group completed the 2-year follow-up, respectively. The results of 2-years follow-up showed that MACE rate of non-smoking group, quitter group and smoking-group was 11.23%, 13.64% and 12.21%(P=0.54), respectively. Multivariable cox regression analysis indicated that smoking status was not an independent predictor for all-cause mortality and TLF.

ABSTRACT

Objectives: This study sought to compare both the safety and efficacy of transradial (TRI) versus transfemoral (TFI) approach in women undergoing percutaneous coronary intervention (PCI) in China. Methods: We retrospectively analyzed data from 5 067 women undergoing PCI in Fuwai Hospital, Beijing, China between 2006 and 2011. 4 105 patients underwent TRI and 962 patients underwent TFI. A One-to-one propensity score matching (PSM) was performed to control for potential biases. A total of 897 pairs were matched. Results: After controlling for confounders using PSM, baseline and procedural characteristics were well-balanced between TRI and TFI groups. Patients undergoing TRI had significantly fewer major post-PCI bleeding (1.0% vs 3.5%, P<0.001) and access site complications (8.5% vs 19.7%,P<0.001) after PSM. There was no statistical differences in the incidence rates of major adverse cardiac events (a composite of cardiac death, myocardial infarction, and target vessel revascularization) during hospitalization (P>0.05). Multiple logistic regression analysis showed that TRI was an independent predictor of reduced major bleeding (OR=0.64, 95%CI: 0.54-0.76, P<0.001) and access site complications (OR=0.67, 95%CI:0.61-0.74, P<0.001). Conclusions: Our result show that TRI is related to reduced major bleeding and access site complications as compared to TFI in Chinese female patients undergoing PCI.

ABSTRACT

Objectives: To observe the prevalence of bleeding and to explore the independent predictors of bleeding in ST-segment elevation acute myocardial infarction patients with fibrinolysis therapy in China. Methods: From January 2013 to June 2014, 1 568 patients undergoing fibrinolysis in the Chinese Acute Myocardial Infarction Registry (CAMI) were prospectively included. Patients were divided into bleeding group (bleeding after fibrinolysis, n=55) and no bleeding group (without bleeding after fibrinolysis, n=1 513). Logistic regression analysis was performed to define the independent predictors of bleeding. Results: The prevalence of bleeding with fibrinolysis in these patients was 3.5% (55/1 568). The fibrinolysis success rate is 86%. Among them, the rate of intracranial bleeding was 0.6%, and the rate of gastrointestinal bleeding was 1.9%. The fibrinolysis success tended to be higher in patients with bleeding (94.1% vs 85.7%, P=0.0589) ,and the mortality rate was significantly higher in patients with bleeding (20.0% vs 7.1%, P=0.0019) . Logistic regression analysis showed that age≥75 years (OR=2.45, 95%CI:1.10-5.46, P=0.0290) and use of rtPA (HR=3.41, 95%CI:1.48~7.86, P=0.0040) were independent predictors of bleeding after fibrinolysis in this patient cohort. Conclusions: The prevalence of bleeding after fibrinolysis in Chinese STEMI patients is low. Older age and rtPA use are independent predictors of bleeding after fibrinolysis in this patient cohort.

ABSTRACT

Objectives:To analyze the safety and efficacy of chemical ablation of anhydrous alcohol combined with gelatin sponge for patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods:The clinical data of 7 HOCM patients, who underwent chemical ablation with anhydrous alcohol and gelatin sponge in Fuwai Hospital from May 2017 to December 2017, were analyzed. Results:There were 5 males and 2 females, with a median age of 56 years (range, 43-67 years), the mean interventricular septum thickness was (19.6 ± 4.8) mm, the number of ablated septal branch was 1-2, the amount of used anhydrous alcohol was 1.4 (1.0-2.0) ml, the amount of applied gelatin sponge was 0.5 (0.1-1.3) ml. After procedure, the left ventricular outflow tract pressure was significantly decreased ([31.6 ± 12.6] mmHg vs [86.4 ± 20.7] mmHg, P<0.001), NYHA cardiac function was significantly improved (1.4 ± 0.5 vs 2.7 ± 0.8, P <0.05), no relevant complications occurred. Conclusions:Chemical ablation with anhydrous alcohol and gelatin sponge is safe and effective for patients with hypertrophic obstructive cardiomyopathy.

ABSTRACT

Objectives:To evaluate the impact of diabetes mellitus on prognosis of coronary artery disease patients after implantation of the novel biodegradable polymer drug eluting stents. Methods:PANDA Ⅲ was a perspective, multi-center, "all-comer", randomized controlled trial. Between Dec. 2013 and Sep. 2014, 2 348 patients from 46 centers were enrolled. All the patients underwent percutaneous coronary intervention, among them 1 174 patients implanted with BuMA stent and 1 174 patients implanted with Excel stent. Mean age was 61.2 ±10.6, 1 658 patients (70.6%) were male, 570 (24.2%) patients presented with diabetes mellitus (DM) and 1 778 (75.7%) without DM. Patients were divided into DM and non-DM groups. Primary endpoint was target lesion failure (TLF), including cardiac death, target vessel myocardial infarction and ischemia driven target lesion revascularization. Secondary endpoints included stent thrombosis and major adverse cardiac events (MACE), defined as a composite of death, myocardial infarction and any revascularization. Results:A total of 558 (97.9%) and 1 704 (95.8%) patients completed 2-year follow-up in DM and non-DM groups. Incidence of TLF in the DM and non-DM group was 8.24% vs. 6.81%, P=0.25, and cardiac death rate was significantly higher in the DM group compared with non-DM group:2.87% vs. 1.12%, P=0.004. Incidence of MACE was similar between two group:13.98% vs. 11.38, P=0.10. Myocardial infarction and any revascularization events were numericallyhigher in the DM group compared with non-DM group, but without statistical significance:5.73% vs. 5.11%, P=0.56; 6.45% vs. 5.46%, P=0.38, respectively. Incidence of all-cause death was significantly higher in the DM group compared with non-DM group:4.30% vs. 2.46%, P=0.03. The results were similar after propensity match analysis. Multivariable analysis showed that DM and baseline SYNTAX score were independent factors for 2-year cardiac death. Conclusions:Two-year incidence of TLF is similar in coronary artery disease patients with or without DM post implantation of biodegradable polymer drug eluting stent or Excel stent, however, the rate of death especially cardiac death is significantly higher in the DM group than in the non-DM group.

ABSTRACT

Objectives:To investigate the predictive value of IABP-SHOCKⅡ risk score for 30-day mortality in Chinese patients with cardiogenic shock after acute myocardial infarction. Methods:A total of 212 hospitalized Chinese patients with cardiogenic shock after acute myocardial infarction were enrolled from June 2014 to July 2017. The IABP-SHOCKⅡrisk score was calculated at admission. The endpoint of this study was all-cause 30-day death. The predictive value of IABP-SHOCKⅡ risk score for these patients was assessed by calculating the area under receiver operating characteristic (ROC) curve. Results:According to the IABP-SHOCKⅡrisk score at admission, the patients were divided into 3 groups:score 0-2 group, n=106; score 3-4 group, n=56 and score 5-9 group, n=50. Patients were older, incidence of cerebral stroke, lactic acid, glucose at admission and creatinine levels were higher. while incidence of TIMI grade 3 was lower in score 3-4 group and score 5-9 group than in score 0-2 group (all P<0.05). Percent of male patients was lower in score 5-9 group than in score 0-2 group (P<0.05). Incidence of cerebral stroke, lactic acid, and creatinine levels were higher. while incidence of TIMI grade 3 was lower in score 5-9 group than in score 3-4 group (all P<0.05). Sixty-eight patients died during the 30 days follow-up, mortality was 6.6%, 37.5% and 80% in the score 0-2 group, score 3-4 group, and score 5-9 group, respectively (P<0.05). The ROC curve analysis showed that AUC was 0.853, and 95%CI was 0.796-0.911. Conclusions:IABP-SHOCKⅡ risk score is suitable for risk stratification and assessment of 30-day mortality in Chinese patients with cardiogenic shock after acute myocardial infarction and may facilitate the clinical decision making to improve the outcome of these patients.

ABSTRACT

Objectives:The purpose of this study was to evaluate the prognostic value of the Thrombolysis In Myocardial Infarction (TIMI) and Global Registry of Acute Coronary Events (GRACE) risk scores for in-hospital mortality in Chinese ST-segment elevation myocardial infarction (STEMI) patients. Methods:Present data are obtained from the prospective, multicenter Chinese AMI (CAMI) registry, 107 hospitals from 31 provinces, municipalities or autonomous districts in China took part in this study. From January 2013 to September 2014, 17886 consecutive ST-segment elevation myocardial infarction patients admitted to these 107 hospitals were enrolled. For each patient, TIMI and GRACE risk scores were calculated using specific variables collected at admission. Their prognostic value on the primary endpoint (in-hospital mortality) was evaluated. Results:Mean age of this patient cohort was (61.9±12.4)years, 76.5% (n=13685) patients were males. The in-hospital mortality was 6.4%(n=1 153)and the median length of hospital stay was 10.0 days. The incidence of cardiac arrest at admission were 4.3% (n=764). Coronary reperfusion therapy including fibrinolytic therapy(n=1782), primary percutaneous coronary intervention (n=7763) and emergent coronary artery bypass grafting (n=10) were applied to 9555 (53.4%) patients and the median of time to reperfusion was 300.0 minutes. The predictive accuracy of TIMI and GRACE for in-hospital mortality was similar:TIMI risk score (AUC) [area under the curve:0.7956; 95% confidence interval (95%CI:0.7822~0.8090)] and GRACE risk score (AUC:0.8096; 95%CI:0.7963~0.8230). Conclusions:The TIMI and GRACE risk score demonstrate similar predictive accuracy for in-hospital mortality and there are some disadvantages in risk stratification by these two risk scores for Chinese STEMI patients.

ABSTRACT

Objectives: To investigate the prognostic value of elevated systolic blood pressure (SBP) at admission in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). Methods: A total of 5 826 consecutive ACS patients undergoing PCI were included. Patients were divided into normal admission SBP (100-139 mmHg, n=4 323) and elevated admission SBP ( ≥ 140 mmHg, n=1 503) groups. All-cause mortality and major adverse cardiovascular and cerebrovascular events (MACCE, including all-cause death, myocardial infarction (MI), revascularization, in-stent thrombosis and stroke) during 2-year follow-up were compared between the two groups. Cox proportional hazard regression models were used to identify the independent risk factors of outcomes. The influence of admission SBP on the outcomes of subgroup patients with unstable angina (n=4 261) was also evaluated. Results: Patients were older (61 vs 57 years, P<0.001), proportions of females (29.3% vs 21.6%, P<0.001), concomitant morbidities (such as hypertension, diabetes mellitus, hyperlipemia, previous MI and cerebral vascular disease) and multi-vessel lesions (77.5% vs 71.0%, P<0.001) were significantly higher in elevated admission SBP group than in normal admission SBP group. During two-years follow-up, all-cause mortality, MACCE, MI and revascularization rates were comparable between two groups (all P>0.05). However, incidence of in-stent thrombosis (1.3% vs 0.7%, P=0.048) and stroke (1.9% vs 1.2%, P=0.038) were significantly higher in elevated admission SBP group than in normal admission SBP group. Subgroup analysis on patients with unstable angina showed that, incidence of in-stent thrombosis and MI were also significantly higher in elevated admission SBP group than in normal admission SBP group (both P<0.05). Cox regression analysis showed that elevated admission SBP was no longer an independent predictor of either in-stent thrombosis or stroke, and age and history of cerebrovascular disease were the independent risk factors of stroke. Conclusions: ACS patients with elevated admission SBP have more cardiovascular risk factors, but elevated admission SBP is not an independent risk factor of long-term outcomes in this patient cohort.
