ABSTRACT

Objective: To investigate the clinical features and long-term prognostic factors of diabetic patients with low or intermediate complexity coronary artery disease (CAD) post percutaneous coronary intervention (PCI). Methods: This was a prospective, single-centre observational study. Consecutive diabetic patients with SYNTAX score (SS)≤32 undergoing PCI between January and December 2013 in Fuwai hospital were included in this analysis. The patients were divided into two groups based on SS, namely SS≤22 group and SS 23-32 group. Multivariate Cox regression analysis was performed to identify independent factors related to poor 5-year prognosis. The primary outcomes were cardiac death and recurrent myocardial infarction, the secondary outcomes were all cause death and revascularization. Results: Of the 3 899 patients included in the study, 2 888 were men (74.1%); mean age was 59.4±9.8 years. There were 3 450 patients in the SS≤22 group and 449 patients in the SS 23-32 group. Compared with SS≤22 group, the incidence of revascularization was higher in SS 23-32 group (18.9% (85/449) vs. 15.2% (524/3450), log-rank P=0.019). There was no significant difference in all-cause death, cardiac death and recurrent myocardial infarction between the two groups (log-rank P>0.05). Multivariate Cox regression analysis showed that age (HR=1.05, 95%CI 1.02-1.08, P<0.001), chronic obstructive pulmonary disease (HR=3.12, 95%CI 1.37-7.07, P=0.007) and creatinine clearance rate (CCr)<60 ml/min (HR=3.67, 95%CI 2.05-6.58, P<0.001) were independent risk factors for 5-year cardiac death, while left ventricular ejection fraction (HR=0.94, 95%CI 0.91-0.96, P<0.001) was a protective factor. Previous PCI (HR=2.04, 95%CI 1.38-3.00, P<0.001), blood glucose level≥11.1 mmol/L on admission (HR=2.49, 95%CI 1.32-4.70, P=0.005) and CCr<60 ml/min (HR=1.85, 95%CI 1.14-2.99, P=0.012) were independent risk factors for 5-year recurrent myocardial infarction. The SS of 23-32 was independently associated with risk of revascularization (HR=1.54, 95%CI 1.09-2.16, P=0.014), after adjusting for residual SS. Residual SS was not a risk factor for 5-year prognosis. Conclusions: In diabetic patients with low-or intermediate complexity CAD, SS 23-32 is associated with increased risk of 5-year revascularization; the clinical characteristics of the patients are associated with the long-term mortality and recurrent myocardial infarction, but not related to revascularization.

ABSTRACT

Objective: To explore and compare the effect of standard or prolonged dual antiplatelet therapy (DAPT) on the long-term prognosis of elderly patients with coronary heart disease complicated with diabetes mellitus after drug-eluting stent (DES) implantation. Methods: Consecutive patients with diabetes mellitus, ≥65 years old, underwent DES implantation, and had no adverse events within 1 year after operation underwent percutaneous coronary intervention (PCI) from January to December 2013 in Fuwai Hospital were enrolled in this prospective cohort study. These patients were divided into three groups according to DAPT duration: standard DAPT duration group (11 ≤ DAPT duration≤ 13 months) and prolonged DAPT duration group (13<DAPT duration≤ 24 months; DAPT duration>24 months). All the patients were followed up at 1, 6 months, 1, 2 and 5 years in order to collect the incidence of major adverse cardiovascular and cerebrovascular events (MACCE), and type 2 to 5 bleeding events defined by the Federation of Bleeding Academic Research (BARC). MACCE were consisted of all cause death, myocardial infarction, target vessel revascularization or stroke. The incidence of clinical adverse events were compared among 3 different DAPT duration groups, and Cox regression model were used to analyze the effect of different DAPT duration on 5-year long-term prognosis. Results: A total of 1 562 patients were enrolled, aged (70.8±4.5) years, with 398 female (25.5%). There were 467 cases in standard DAPT duration group, 684 cases in 13<DAPT duration≤ 24 months group and 411 cases in DAPT duration>24 months group. The patients in standard DAPT duration group and the prolonged DAPT duration groups accounted for 29.9% (467/1 562) and 70.1% (1 095/1 562), respectively. The 5-year follow-up results showed that the incidence of all-cause death in 13<DAPT duration≤ 24 months group (4.8%(33/684) vs. 8.6%(40/467),P=0.011) and DAPT duration>24 month group(4.1%(17/411) vs. 8.6%(40/467),P=0.008) were significantly lower than in standard DAPT group. The incidence of myocardial infarction in 13<DAPT duration≤ 24 months group was lower than in standard DAPT duration group (1.9%(13/684) vs. 5.1%(24/467),P=0.002). The incidence of MACCE in 13<DAPT duration≤ 24 months group was the lowest (standard DAPT duration group, 13<DAPT duration≤ 24 months group and DAPT duration>24 month group were 19.3% (90/467), 12.3% (84/684), 20.2% (83/411), respectively, P<0.001). There was no significant difference in the incidence of stroke and bleeding events among the three groups (all P>0.05). Multivariate Cox analysis showed that compared with the standard DAPT group, prolonged DAPT to 13-24 months was negatively correlated with MACCE (HR=0.601, 95%CI 0.446-0.811, P=0.001), all-cause death (HR=0.568, 95%CI 0.357-0.903, P=0.017) and myocardial infarction (HR=0.353, 95%CI 0.179-0.695, P=0.003). DAPT>24 months was negatively correlated with all-cause death (HR=0.687, 95%CI 0.516-0.913, P=0.010) and positively correlated with revascularization (HR=1.404, 95%CI 1.116-1.765, P=0.004). There was no correlation between prolonged DAPT and bleeding events. Conclusions: For elderly patients with coronary heart disease complicated with diabetes mellitus underwent DES implantation, and had no MACCE and bleeding events within 1 year after operation, appropriately prolonging of the DAPT duration is related to the reduction of the risk of cardiovascular adverse events. Patients may benefit the most from the DAPT between 13 to 24 months. In addition, prolonging DAPT duration does not increase the incidence of bleeding events in this patient cohort.

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

Objectives@#The aims of this study were to assess the associations between parity and metabolic syndrome (MetS) and its components and to evaluate the effects of body mass index (BMI) on these associations.@*Methods@#A total of 5,674 women were enrolled from Jidong and Kailuan communities (Tangshan, Hebei) in Northern China. All participants completed standardized questionnaires, physical examination, and biochemical measurements. Logistic regression analysis was used to test the associations.@*Results@#Compared with women with parity of one, nulliparous women had decreased odds ratios ( s ); those with parity of two had odds of abdominal obesity [ = 1.45, 95% confidence interval ( ) 1.17-1.81, < 0.001], high blood pressure ( = 1.26, 95% 1.03-1.54, = 0.025), elevated fasting glucose levels ( = 1.36, 95% 1.03-1.79, = 0.029), and MetS ( = 1.39, 95% 1.13-1.73, = 0.002); and those with parity of three or more had increased odds of elevated triglyceride levels ( = 1.42, 95% 1.04-1.94, = 0.027) and MetS ( = 1.50, 95% 1.10-2.05, = 0.011) after complete adjustment for confounders. Furthermore, BMI and age subgroups partially modified the associations between parity and MetS and its components.@*Conclusions@#Parity is positively associated with MetS and select components in women. BMI is an important modifier involved in the associations between parity and MetS.

ABSTRACT

Objective: To investigate the impact of type 2 diabetes mellitus on progression and revascularization of coronary non-target lesions in patients with coronary heart disease. Methods: From January 2010 to September 2014, we retrospectively analyzed the clinical data of patients with coronary heart disease who underwent two consecutive coronary angiographies at Fuwai Hospital. At least one coronary non-target lesion was recorded at the first procedure in these patients. Patients were grouped according to the diagnose of type 2 diabetes mellitus. Demographic features, risk factors of coronary heart disease, laboratory results as well as characteristics of coronary non-target lesions were collected at baseline (first coronary angiography) and follow-up (second coronary angiography). Lesion progression was defined by quantitative coronary angiography analysis. Lesions revascularization was recorded. Multivariable Cox regression analysis was used to define the impacts of diabetes mellitus on progression and revascularization of non-target lesions. Subgroup analysis in diabetic and non-diabetic groups were further performed. Receiver operating characteristics curve was used to identify the predictive value of HbA1c. Results: A total of 1 255 patients were included, and 1 003(79.9%) were male, age was(58.0±9.7) years old. And 486 patients were diagnosed with type 2 diabetes mellitus. Follow-up time was (14.8±4.5) months. Compared with non-diabetic group, diabetic group were older with less male and had higher BMI index as well as higher prevalence of hypertension, dyslipidemia, prior myocardial infarction and prior percutaneous coronary intervention(all P<0.05). Diabetic patients also had higher level of white blood cells, erythrocyte sedimentation rate, C-reactive protein, endothelin and HbA1c at both baseline and follow-up compared with non-diabetic patients (all P<0.01). There was no significant difference on progression of non-target lesions (20.0%(97/486) vs. 18.5%(142/769), P=0.512), revascularization of non-target lesions (13.2%(64/486) vs. 15.9%(122/769), P=0.190) and non-target lesion related myocardial infarction(1.9%(9/486) vs. 1.3%(10/769), P=0.436) between diabetic and non-diabetic patients. Multivariable Cox regression analysis revealed that diabetes mellitus was not an independent predictor for progression and revascularization of non-target lesions (Both P>0.05). Subgroup analysis in diabetic patients showed that baseline HbA1c level(HR=1.160, 95%CI 1.009-1.333, P=0.037) was an independent predictor for non-target lesion progression. Cut-off value of HbA1c was 6.5% (Area Under Curve(AUC) 0.57, specificity 88.7%; sensitivity 24.2%, P=0.046) by receiver operating characteristics curve. Patients with HbA1c level above 6.5% had 2.8 times higher risk of lesion progression compared with patients with HbA1c level below 6.5% (HR=2.838, 95%CI 1.505-5.349, P=0.001). Compared with non-diabetic patients, diabetic patients with HbA1c below 6.5% also had lower risk of lesion progression (HR=0.469, 95%CI 0.252-0.872, P=0.012). ST-segment elevated myocardial infarction was an independent predictor for revascularization of non-target lesions in diabetic patients. Conclusion: Type 2 diabetes mellitus is not an independent predictor for progression and revascularization of coronary non-target lesions in patients with coronary heart disease. However, elevated HbA1c level is a risk factor for progression of non-target lesion in patients with type 2 diabetes mellitus.

ABSTRACT

Objective: To analyze the association between plasma high-density lipoprotein cholesterol (HDL-C) levels and the severity of coronary artery disease, and to evaluate the impact of HDL-C levels on long-term outcomes in patients underwent percutaneous coronary intervention (PCI). Methods: A total of 10 458 consecutive patients underwent PCI from January 2013 to December 2013 at Fuwai hospital were enrolled in this study. Patients were divided into three groups according to HDL-C tertiles: low HDL-C group (HDL-C≤0.89 mmol/L, n=3 525), median HDL-C group (HDL-C>0.89-1.11 mmol/L, n=3 570) and high HDL-C group (HDL-C>1.11 mmol/L, n=3 363). SYNTAX score was used to evaluate the severity of coronary artery disease, linear regression was used to analyze the relationship of HDL-C and SYNTAX score. Kaplan-Meier survival analysis was used to compare the outcomes among the three groups. Multivariate Cox regression was used to define the potential associations of HDL-C and outcomes. Results: The HDL-C level was (1.03±0.28) mmol/L and the SYNTAX score was 11.7±8.1. Patients were older, proportion of female, stable angina pectoris, successful PCI and left ventricular eject fraction value were higher, while incidence of diabetes mellitus was lower, hyperlipidemia, old myocardial infraction, smoking history and left main and three vessels disease were lower in high HDL-C group (all P<0.05). Patients in high HDL-C group also had the lowest SYNTAX score (12.2±8.4 vs. 11.7±8.1 vs. 11.2±7.8, P<0.001). Both univariate and multivariate linear regression analysis showed that HDL-C was negatively associated with SYNTAX score, e.g. Univariate analysis: β=-0.046, P<0.001; Multivariate analysis: β=-0.058, P=0.001. And 10 400 (99.4%) patients completed 2-year follow up. At 2-year follow-up, there were no difference in all-cause death, cardiac death, myocardial infarction, revascularization, stroke, major adverse cardiovascular and cerebral events (MACCE) and stent thrombosis among three groups (P for trend>0.05), while patient in high HDL-C group experienced the highest BARC type 2 bleeding events (P for trend=0.018). Multivariate Cox regression analysis showed that HDL-C level was not an independent risk factor of 2-year adverse ischemia events (P>0.05) and 2-year bleeding events (P>0.05). Conclusion: In patients underwent PCI, plasma HDL-C level is negatively associated with SYNTAX score, but not an independent risk factor of ischemic and bleeding events post PCI.

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.

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. The PARIS bleeding score showed a moderate predictive value for MB in the overall population (AUROC: 0.568, 95% CI: 0.532-0.605; P < 0.001) and acute coronary syndrome (ACS) subgroup (AUROC: 0.578, 95% CI: 0.530-0.626; P = 0.001) and tended to be predictive in the non-ACS subgroup (AUROC: 0.556, 95% CI: 0.501-0.611; P = 0.054).</p><p><b>Conclusion</b>The PARIS bleeding score shows good clinical value for risk stratification and has a significant, but relatively limited, prognostic value for out-of-hospital bleeding in the Chinese population after PCI.</p>

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

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

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

<p><b>BACKGROUND</b>Prior studies have reported controversial conclusions regarding the risk of adverse cardiovascular events in patients using proton-pump inhibitors (PPIs) combined with clopidogrel therapy, causing much uncertainty in clinical practice. We sought to evaluate the safety of PPIs use among high-risk cardiovascular patients who underwent percutaneous coronary intervention (PCI) in a long-term follow-up study.</p><p><b>METHODS</b>A total of 7868 consecutive patients who had undergone PCI and received dual antiplatelet therapy (DAPT) at a single center from January 2013 to December 2013 were enrolled. Adenosine diphosphate (ADP)-induced platelet aggregation inhibition was measured by modified thromboelastography (mTEG) in 5042 patients. Propensity score matching (PSM) was applied to control differing baseline factors. Cox proportional hazards regression was used to evaluate the 2-year major adverse cardiovascular and cerebrovascular events (MACCEs), as well as individual events, including all-cause death, myocardial infarction, unplanned target vessel revascularization, stent thrombosis, and stroke.</p><p><b>RESULTS</b>Among the whole cohort, 27.2% were prescribed PPIs. The ADP-induced platelet aggregation inhibition by mTEG was significantly lower in PPI users than that in non-PPI users (42.0 ± 30.9% vs. 46.4 ± 31.4%, t = 4.435, P < 0.001). Concomitant PPI use was not associated with increased MACCE through 2-year follow-up (12.7% vs. 12.5%, χ2 = 0.086, P = 0.769). Other endpoints showed no significant differences after multivariate adjustment, regardless of PSM.</p><p><b>CONCLUSION</b>In this large cohort of real-world patients, the combination of PPIs with DAPT was not associated with increased risk of MACCE in patients who underwent PCI at up to 2 years of follow-up.</p>

ABSTRACT

<p><b>BACKGROUND</b>Restenosis of bare-metal stents (BMS) and drug-eluting stents (DES) has been increasingly treated with sirolimus-eluting stents (SES), but the long-term outcomes are unknown.</p><p><b>METHODS</b>In our study, 388 consecutive patients (144 DES restenosis and 244 BMS restenosis) with 400 lesions (147 DES restenosis and 253 BMS restenosis) treated with SES were included. The rates of target lesion revascularization (TLR) and major adverse cardiac events (MACE) at 42 months were analyzed.</p><p><b>RESULTS</b>At the mean follow-up of 42 months, the rates of death (3.5% vs. 3.3%, P = 1.000) and myocardial infarction (2.8% vs. 1.2%, P = 0.431) in the DES group and BMS group were comparable. Compared with the BMS group, ischemia-driven TLR occurred with a higher frequency in the DES group (18.8% vs. 10.7%, P = 0.024). This translated into an increased rate of MACE in the DES group (22.2% vs. 14.0%, P = 0.034). Stent thrombosis occurred with a similar frequency in both groups (2.8% vs. 1.6%, P = 0.475). Multivariate analysis showed that DES restenosis (OR = 1.907, 95%CI 1.108 - 3.285, P = 0.020) and smoking (OR = 2.069; 95%CI 1.188 - 3.605; P = 0.010) were independent predictors of MACE.</p><p><b>CONCLUSIONS</b>Although SES implantation appears to be safe and effective, it was associated with higher TLR recurrence for DES than BMS restenosis.</p>

ABSTRACT

<p><b>BACKGROUND</b>Late stent thrombosis (LST) is still concerned by interventional cardiologists in daily clinical practice. This study aimed to compare the incidence of LST after implantation of different drug-eluting stents (DES) in coronary heart disease (CHD) patients in the real world.</p><p><b>METHODS</b>From December 2001 to February 2009, a total of 11 875 consecutive CHD patients undergone DES implantation were enrolled in this single-center registry study. Patients with acute ST-segment elevation myocardial infarction, mixed DES implantation, restenosis lesions, and patients who could not take dual antiplatelet medication and those who were contraindicated for coronary interventional treatment were excluded. All patients were treated with completed dual antiplatelet medications for at least 9 months after DES deployment. The follow-up was completed by outpatient visits, letter correspondence, phone calls and coronary angiography. Definite LST was diagnosed according to the Academic Research Consortium (ARC) definition.</p><p><b>RESULTS</b>Cypher or Cypher Select stents were implanted in 4104 cases, Taxus or Taxus Liberty stents in 2271 cases and Firebird stents (Chinese rapamycin-eluting stents) in 5500 cases. One-year follow-up was completed in 9693 patients, including 3346 cases with Cypher or Cypher Select stents, 1529 cases with Taxus or Taxus Liberty stents and 4818 cases with Firebird stents. Two- and three-year follow-up results were obtained in 7133 and 4353 patients, respectively, including 2410 and 1760 cases with Cypher or Cypher Select stents, 1285 and 900 cases with Taxus or Taxus Liberty stents as well as 3438 and 1693 cases with Firebird stents. One-year follow-up results showed that the incidence of LST was 1.08% in patients with Cypher or Cypher Select stents, 1.24% in those with Taxus or Taxus Liberty stents and 0.71% in those with Firebird stents; there was no significant difference between those with Cypher or Cypher Select and Firebird stents, but there was significant difference between those with Taxus or Taxus Liberty and Firebird stents (P = 0.044). The incidence of LST at the 2- and 3-year follow-up was 1.33% and 1.70% in those with Cypher or Cypher Select stents, 1.40% and 1.70% in those with Taxus or Taxus Liberty stents, and 0.83% and 0.95% in those with Firebird stents, respectively. There were no significant differences among the three groups.</p><p><b>CONCLUSIONS</b>This study indicates that first-generation DES are acceptable to treat complex coronary lesions, and there is no significant difference of LST for three different DES.</p>

ABSTRACT

<p><b>AIM</b>The mechanism of vascular endothelial growth factor165 (VEGF165) on intracellular free magnesium ([Mg2+]i) in human umbilical vein endothelial cells (HUVECs) was investigated.</p><p><b>METHODS</b>[Mg2+]i in HUVECs loaded with fluorescent magnesium indicator mag-fura-2 were quantitatively detected the use of intracellular cation measurement system.</p><p><b>RESULTS</b>VEGF165 significantly increased [Mg2+]i in the extracellular Mg2+ and this effect could be blocked by pretreatment with tyrosine kinase inhibitors (tyrphostin A23 and genistein), phosphatidylinositol 3-kinase (PI3K) inhibitors (wortmannin and LY294002) and phospholipase Cgamma (PLCgamma) inhibitor (U73122). In contrast, phospholipase Cgamma (PLCgamma) inhibitor analog (U73343), mitogen-activated protein kinase inhibitors (SB202190 and PD98059) had no effect on the VEGF165-induced [Mg2+]i increase.</p><p><b>CONCLUSION</b>The increase of [Mg2+]i by VEGF165 originates from intracellular Mg2+ pool through tyrosine kinase/ PI3K/PLCgamma-dependent signaling pathways.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To compare the short and long-term clinical and angiographic outcomes of drug-eluting stents (DES) versus cutting balloon angioplasty followed by bare metal stents (CBA + BMS) for the treatment of ostial lesions of the left anterior descending coronary artery (LAD).</p><p><b>METHODS</b>A total of 51 consecutive patients with LAD ostial lesions were treated by DES and all patients had completed 2-year clinical follow-up, 50 consecutive patients with LAD ostial lesions treated by CBA + BMS and followed up for 2 years prior to the DES era (May 2000 to November 2003) served as control group.</p><p><b>RESULTS</b>In DES group, one patient experienced acute myocardial infarction (AMI) during hospitalization, the in-hospital major adverse cardiac event (MACE) was 1.96% (1/51), angiography follow-up data at 6-8 months were available in 29 patients and the in-DES restenosis was 10.3% (3/29), at 2-year clinical follow-up, 1 patient died, 4 patients received target lesion revascularization. Total MACE rate was 9.8% (5/51). In CBA + BMS group, there was no in-hospital death and AMI. Angiographic follow-up at 6-8 months was completed in 28 cases and in-stent restenosis rate was 17.9% (5/28). During 2-year follow-up, there was no death and AMI and 6 patients underwent target lesion revascularization. MACE rate was 12% (6/50) in this group.</p><p><b>CONCLUSION</b>This study showed that both clinical and angiographic outcomes were comparable between DES and CBA + BMS treated patients with LAD ostial lesions during the 2-year follow up period.</p>

ABSTRACT

<p><b>BACKGROUND</b>Randomized clinical trials have demonstrated equivalent safety to bare-metal stents after drug-eluting stents (DES) implantation. However, the DES thrombosis in randomized trials could not be comparable to those observed in clinical practice, frequently including off-label indications. This study sought to assess the incidence of DES thrombosis after implantation of DES in patients with real world coronary artery disease (CAD) in China.</p><p><b>METHODS</b>From December 2001 to April 2007, 8190 consecutive patients received the treatment with DES, 5412 patients completed one year follow-up: 2210 with sirolimus-eluting stent Cypher, 1238 with paclitaxel-eluting stent Taxus and 1964 with Chinese sirolimus-eluting stent Firebird. After two years of follow-up, there were 2176 patients (1245 Cypher, 558 Taxus and 373 Firebird). All patients were treated with aspirin and clopidogrel over at least 9 months.</p><p><b>RESULTS</b>Among 8190 patients, 17 patients had acute stent thrombosis (0.24%): 7 in the Cypher group, 4 Taxus and 6 Firebird; 23 patients had subacute stent thrombosis: 8 Cypher, 6 Taxus and 9 Firebird. The incidence of acute and subacute thrombosis was 0.49%: 0.50% Cypher, 0.63% Taxus and 0.41% Firebird. The incidence of late thrombosis at one year followup was 0.63%: 0.63% Cypher, 0.88% Taxus and 0.46% Firebird; at two year follow-up the incidence was 0.74%: 0.72% Cypher, 0.90% Taxus and 0.54% Firebird. There was no significant difference among three groups at 1 year and 2 years follow-up.</p><p><b>CONCLUSION</b>The first generation DES in the treatment of complex lesions are safe and effective if patients are aggressively treated with dual antiplatelet agents.</p>
