Background
The value of prolonged bivalirudin infusion after percutaneous coronary intervention (PCI) in acute coronary syndrome (ACS) patients with or without ST-segment elevation remains unclear.Objectives
The purpose of this study was to assess efficacy and safety of a full or low post-PCI bivalirudin regimen in ACS patients with or without ST-segment elevation.Methods
The MATRIX program assigned bivalirudin to patients without or with a post-PCI infusion at either a full (1.75 mg/kg/h for ≤4 h) or reduced (0.25 mg/kg/h for ≤6 h) regimen at the operator’s discretion. The primary endpoint was the 30-day composite of urgent target-vessel revascularization, definite stent thrombosis, or net adverse clinical events (composite of all-cause death, myocardial infarction, or stroke, or major bleeding).Results
Among 3,610 patients assigned to bivalirudin, 1,799 were randomized to receive and 1,811 not to receive a post-PCI bivalirudin infusion. Post-PCI full bivalirudin was administered in 612 (ST-segment elevation myocardial infarction [STEMI], n = 399; non–ST-segment elevation acute coronary syndromes [NSTE-ACS], n = 213), whereas the low-dose regimen was administered in 1,068 (STEMI, n = 519; NSTE-ACS, n = 549) patients. The primary outcome did not differ in STEMI or NSTE-ACS patients who received or did not receive post-PCI bivalirudin. However, full compared with low bivalirudin regimen remained associated with a significant reduction of the primary endpoint after multivariable (rate ratio: 0.21; 95% CI: 0.12 to 0.35; p < 0.001) or propensity score (rate ratio: 0.16; 95% CI: 0.09 to 0.26; p < 0.001) adjustment. Full post-PCI bivalirudin was associated with improved outcomes consistently across ACS types compared with the no post-PCI infusion or heparin groups.Conclusions
In ACS patients with or without ST-segment elevation, the primary endpoint did not differ with or without post-PCI bivalirudin infusion but a post-PCI full dose was associated with improved outcomes when compared with no or low-dose post-PCI infusion or heparin (Minimizing Adverse Haemorrhagic Events by TRansradial Access Site and Systemic Implementation of angioX [MATRIX]; NCT01433627). 相似文献2.

Objectives
The authors sought to investigate the impact of diabetes mellitus (DM) on outcomes following contemporary drug-eluting stent (DES) implantation in the BIONICS (BioNIR Ridaforolimus Eluting Coronary Stent System in Coronary Stenosis) trial.Background
Patients with DM are at increased risk for adverse events following percutaneous coronary intervention (PCI).Methods
A prospective, multicenter, 1:1 randomized trial was conducted to evaluate in a noninferiority design the safety and efficacy of ridaforolimus-eluting stents versus zotarolimus-eluting stents among 1,919 patients undergoing PCI. Randomization was stratified to the presence of medically treated DM, and a pre-specified analysis compared outcomes according to the presence or absence of DM up to 2 years.Results
The overall prevalence of DM was 29.1% (559 of 1,919). DM patients had higher body mass index, greater prevalence of hyperlipidemia and hypertension, and smaller reference vessel diameter. One-year target lesion failure (cardiac death, target vessel myocardial infarction, or ischemia-driven target lesion revascularization) was significantly higher among diabetic patients (7.8% vs. 4.2%; p = 0.002), mainly due to higher target lesion revascularization (4.5% vs. 2.0%; p = 0.002). Rates of cardiac death, myocardial infarction, and stent thrombosis did not statistically vary. Among 158 patients undergoing 13-month angiographic follow-up, restenosis rates were 3 times higher in diabetic patients compared with nondiabetic patients (15.2% vs. 4.7%; p = 0.01). Clinical and angiographic outcomes were similar between ridaforolimus-eluting stent– and zotarolimus-eluting stent–treated patients.Conclusions
Despite advances in interventional therapies, and the implementation of new-generation DES, diabetic patients still have worse angiographic and clinical outcomes compared with nondiabetic patients undergoing PCI. 相似文献3.

Objectives
The aim of this study was to evaluate the utility of distal protection during percutaneous coronary intervention (PCI) in patients with acute coronary syndromes at high risk for distal embolization.Background
The results of previous clinical trials indicated that the routine use of distal protection in patients with ST-segment elevation myocardial infarction did not improve clinical outcomes. However, selective use of distal protection by means of a filter-based distal protection system has not been evaluated.Methods
Two hundred patients with acute coronary syndromes who had native coronary artery lesions and attenuated plaque with longitudinal length ≥5 mm on pre-PCI intravascular ultrasound were randomly assigned to undergo PCI with distal protection or conventional treatment.Results
The primary endpoint (no-reflow phenomenon) occurred in 26 patients (26.5%) in the distal protection group and 39 patients (41.7%) in the conventional treatment group (p = 0.026), and the corrected TIMI (Thrombolysis In Myocardial Infarction) frame count after revascularization was significantly lower in the distal protection group (23 vs. 30.5; p = 0.0003). The incidence of cardiac death, cardiac arrest, cardiogenic shock after revascularization requiring defibrillation, cardiopulmonary resuscitation, or extracorporeal membrane oxygenation was significantly lower in the distal protection group than in the conventional treatment group (0% vs. 5.2%; p = 0.028).Conclusions
The use of distal embolic protection applied with a filter device decreased the incidence of the no-reflow phenomenon and was associated with fewer serious adverse cardiac events after revascularization than conventional PCI in patients with acute coronary syndromes with attenuated plaque ≥5 mm in length.

ObjectivesThe aim of this study was to assess the impact of access-site crossover in patients with acute coronary syndrome undergoing invasive management via radial or femoral access.BackgroundThere are limited data on the clinical implications of access-site crossover.MethodsIn the MATRIX (Minimizing Adverse Haemorrhagic Events by Transradial Access Site and Systemic Implementation of Angiox)–Access trial, 8,404 patients with acute coronary syndrome were randomized to radial or femoral access. Patients undergoing access-site crossover or successful access site were investigated. Thirty-day coprimary outcomes were a composite of death, myocardial infarction, or stroke (major adverse cardiovascular events [MACE]) and a composite of MACE or Bleeding Academic Research Consortium type 3 or 5 bleeding (net adverse clinical events [NACE]).ResultsAccess-site crossover occurred in 183 of 4,197 patients (4.4%) in the radial group (mainly to femoral access) and 108 of 4,207 patients (2.6%) in the femoral group (mainly to radial access). In multivariate analysis, the risk for coprimary outcomes was not significantly higher with radial crossover compared with successful radial (MACE: adjusted rate ratio [adjRR]: 1.25; 95% confidence interval [CI]: 0.81 to 1.93; p = 0.32; NACE: adjRR: 1.40; 95% CI: 0.94 to 2.06; p = 0.094) or successful femoral access (MACE: adjRR: 1.17; 95% CI: 0.76 to 1.81; p = 0.47; NACE: adjRR: 1.26; 95% CI: 0.86 to 1.86; p = 0.24). Access site–related Bleeding Academic Research Consortium type 3 or 5 bleeding was higher with radial crossover than successful radial access. Femoral crossover remained associated with higher risks for MACE (adjRR: 1.84; 95% CI: 1.18 to 2.87; p = 0.007) and NACE (adjRR: 1.69; 95% CI: 1.09 to 2.62; p = 0.019) compared with successful femoral access. Results remained consistent after excluding patients with randomized access not attempted.ConclusionsCrossover from radial to femoral access abolishes the bleeding benefit offered by the radial over femoral artery but does not appear to increase the risk for MACE or NACE compared with successful radial or femoral access.

Objectives
The aim of this study was to investigate the impact of pre-diabetes (pre-DM) on coronary plaque characteristics and ischemic outcomes in patients with acute coronary syndromes (ACS).Background
Pre-DM (i.e., the early stages of glucometabolic disturbance) is common among patients with ACS, but the extent to which pre-DM influences coronary plaque characteristics and the risk for adverse ischemic events is unclear.Methods
In the PROSPECT (Providing Regional Observations to Study Predictors of Events in Coronary Tree) study, patients with ACS underwent quantitative coronary angiography, grayscale intravascular ultrasound, and radiofrequency intravascular ultrasound after successful percutaneous coronary intervention. Patients were divided into 3 groups according to their glucometabolic status, as defined by the American Diabetes Association: normal glucose metabolism (NGM), pre-DM, and diabetes mellitus (DM). These groups were compared with regard to coronary plaque characteristics and the risk for major adverse cardiac events (MACEs) (defined as cardiac death or arrest, myocardial infarction, or rehospitalization for unstable or progressive angina).Results
Among 547 patients, 162 (29.6%) had NGM, 202 (36.9%) had pre-DM, and 183 (33.4%) had DM. There were no significant differences between the groups with regard to intravascular ultrasound findings indicative of vulnerable plaques. Patients with DM had a higher crude rate of MACEs than those with pre-DM or NGM (25.9% vs. 16.3% and 16.1%; p = 0.03 and p = 0.02, respectively). In an adjusted Cox regression model using NGM as the reference group, DM (hazard ratio: 2.20; 95% confidence interval: 1.25 to 3.86; p = 0.006) but not pre-DM (hazard ratio: 1.29; 95% confidence interval: 0.71 to 2.33; p = 0.41) was associated with increased risk for MACEs.Conclusions
Impaired glucose metabolism is common among patients presenting with ACS. DM but not pre-DM is associated with an increased risk for MACEs. Thus, preventing patients from progressing from pre-DM to DM is important. (PROSPECT: An Imaging Study in Patients With Unstable Atherosclerotic Lesions; NCT00180466) 相似文献7.

Objectives
The aim of this study was to compare the thin-strut biodegradable-polymer everolimus-eluting platinum-chromium stent (EES) with the biodegradable-polymer biolimus-eluting stainless-steel stent (BES).Background
Currently available drug-eluting coronary stents have been refined to reduce the risk for coronary events following implantation.Methods
This randomized, multicenter, all-comers, noninferiority trial was undertaken at 3 sites in western Denmark. Patients with clinical indications for percutaneous coronary intervention were eligible for inclusion. Patients were randomly assigned (1:1) to either EES or BES. The primary endpoint, target lesion failure, was a composite of safety (cardiac death and myocardial infarction not clearly attributable to a nontarget lesion) and efficacy (target lesion revascularization) at 12 months, analyzed using intention-to-treat principles. The trial was powered to assess target lesion failure noninferiority of the EES compared with the BES with a predetermined noninferiority margin of 3%.Results
A total of 1,385 patients were assigned to treatment with EES and 1,369 patients to treatment with BES. The analysis showed that 55 patients (4.0%) assigned to the EES and 60 (4.4%) assigned to the BES met the primary endpoint (absolute risk difference 0.4%; upper limit of 1-sided 95% confidence interval: 1.7%; p < 0.001).Conclusions
At 1-year follow-up, the EES was found to be noninferior to the BES with respect to target lesion failure. (Everolimus-eluting SYNERGY Stent Versus Biolimus-Eluting Biomatrix NeoFlex Stent—SORT-OUT VIII; NCT02093845) 相似文献8.

ObjectivesThe purpose of this study was to determine the efficacy and safety of radial versus femoral access in women undergoing coronary angiography/intervention.BackgroundThe risk of bleeding and vascular access site complications are higher in women than in men.MethodsIn a pre-specified RIVAL (RadIal Vs femorAL access for coronary intervention) subgroup analysis, we compared outcomes in women (n = 1,861) and men (n = 5,160) randomized to radial versus femoral access.ResultsOverall, women were at higher risk of major vascular complications compared with men (4.7% vs. 1.7%; p < 0.0001). Major vascular complications were significantly reduced with radial access in women (3.1% vs. 6.1%; hazard ratio [HR]: 0.5; 95% confidence interval [CI]: 0.32 to 0.78; p = 0.002) and in men (0.7% vs. 2.8%; HR: 0.27; 95% CI: 0.17 to 0.45; p < 0.0001; interaction p = 0.092). Crossover rates were higher with radial compared with femoral access in women (11.1% vs. 1.9%; HR: 5.88; p < 0.0001) and men (6.3% vs. 1.9%; HR: 3.32; p < 0.0001; interaction p = 0.054). Percutaneous coronary intervention (PCI) success rates were similar irrespective of access site (women: HR: 1.05; p = 0.471; men: HR: 1.00; p = 0.888; interaction p = 0.674), with no differences in PCI complications. In multivariable analyses, female sex was an independent predictor of major vascular complications (HR: 2.39; 95% CI: 1.76 to 3.25; p < 0.0001). There were consistent findings for women and men, with no difference for the primary composite endpoint of death, myocardial infarction, stroke, and non–coronary artery bypass grafting bleeding (women: 3.9% vs. 5.0%; HR: 0.77; 95% CI: 0.50 to 1.19; men: 3.54% vs. 3.5%; HR: 1.00; 95% CI: 0.75 to −1.34; interaction p = 0.325).ConclusionsWomen undergoing coronary angiography and PCI have a higher risk of vascular access site complications compared with men, and radial access is an effective method to reduce these complications. 相似文献

Objectives
This study examined the frequency and outcomes of radial access for chronic total occlusion (CTO) percutaneous coronary intervention (PCI).Background
Radial access improves the safety of PCI, but its role in CTO PCI remains controversial.Methods
We compared the clinical, angiographic, and procedural characteristics of 3,790 CTO interventions performed between 2012 and 2018 via radial-only access (RA) (n = 747) radial-femoral access (RFA) (n = 844) and femoral-only access (n = 2,199) access at 23 centers in the United States, Europe, and Russia.Results
Patients’ mean age was 65 ± 10 years, and 85% were men. Transradial access (RA and RFA) was used in 42% of CTO interventions and significantly increased over time from 11% in 2012 to 67% in 2018 (p < 0.001). RA patients were younger (age 62 ± 10 years vs. 64 ± 10 years and 65 ± 10 years; p < 0.001), less likely to have undergone prior coronary artery bypass graft surgery (18% vs. 39% and 35%; p < 0.001), and less likely to have undergone prior PCI (60% vs. 63% and 66%; p = 0.005) compared with those who underwent RFA and femoral-only access PCI. RA CTO PCI lesions had lower J-CTO (Multicenter CTO Registry in Japan) (2.1 ± 1.4 vs. 2.6 ± 1.3 and 2.5 ± 1.3; p < 0.001) and PROGRESS CTO (Prospective Global Registry for the Study of Chronic Total Occlusion Intervention) complication (2.3 ± 1.9 vs. 3.2 ± 2.0 and 3.2 ± 1.9; p < 0.001) scores. The mean sheath size was significantly smaller in the RA group (6.6 ± 0.7 vs. 7.0 ± 0.6 and 7.3 ± 0.8; p < 0.0001), although it increased with lesion complexity. Antegrade dissection re-entry (20% vs. 33% and 32%; p < 0.001) was less commonly used with RA, whereas use of retrograde techniques was highest with RFA (47%). The overall rates of technical success (89% vs. 88% vs. 86%; p = 0.061), procedural success (86% vs. 85% vs. 85%; p = 0.528), and in-hospital major complication (2.47% vs. 3.40% vs. 2.18%; p = 0.830) were similar in all 3 groups, whereas major bleeding was lower in the RA group (0.55% vs. 1.94% and 0.88%; p = 0.013).Conclusions
Transradial access is increasingly being used for CTO PCI and is associated with similar technical and procedural success and lower major bleeding rates compared with femoral-only access interventions.

Objectives
The aim of this study was to compare complete revascularization with a culprit-only strategy in patients presenting with ST-segment elevation myocardial infarction (MI) and multivessel disease by a meta-analysis of randomized trials.Background
Although several trials have compared complete with culprit-only revascularization in ST-segment elevation MI, it remains unclear whether complete revascularization may lead to improvement in hard endpoints (death and MI).Methods
Randomized trials comparing complete revascularization with culprit-only revascularization in patients with ST-segment elevation MI without cardiogenic shock were identified by a systematic search of published research. Random-effects meta-analysis was performed, comparing clinical outcomes in the 2 groups.Results
Eleven trials were identified, including a total of 3,561 patients. Compared with a culprit-only strategy, complete revascularization significantly reduced risk for death or MI (relative risk [RR]: 0.76; 95% confidence interval [CI]: 0.58 to 0.99; p = 0.04). Meta-regression showed that performing complete revascularization at the time of primary percutaneous coronary intervention (PCI) was associated with better outcomes (p = 0.016). The 6 trials performing complete revascularization during primary PCI (immediate revascularization) were associated with a significant reduction in risk for both total mortality (RR: 0.62; 95% CI: 0.39 to 0.97; p = 0.03) and MI (RR: 0.40; 95% CI: 0.25 to 0.66; p < 0.001), whereas the 5 trials performing only staged revascularization did not show any significant benefit in either total mortality (RR: 1.02; 95% CI: 0.65 to 1.62; p = 0.87) or MI (RR: 1.04; 95% CI: 0.48 to 1.68; p = 0.86).Conclusions
When feasible, complete revascularization with PCI can significantly reduce the combined endpoint of death and MI. Complete revascularization performed during primary PCI was also associated with significant reductions in both total mortality and MI, whereas staged revascularization did not improve these outcomes. 相似文献13.

Objectives
The aim of this study was to investigate the clinical outcomes of patients deferred from coronary revascularization on the basis of instantaneous wave-free ratio (iFR) or fractional flow reserve (FFR) measurements in stable angina pectoris (SAP) and acute coronary syndromes (ACS).Background
Assessment of coronary stenosis severity with pressure guidewires is recommended to determine the need for myocardial revascularization.Methods
The safety of deferral of coronary revascularization in the pooled per-protocol population (n = 4,486) of the DEFINE-FLAIR (Functional Lesion Assessment of Intermediate Stenosis to Guide Revascularisation) and iFR-SWEDEHEART (Instantaneous Wave-Free Ratio Versus Fractional Flow Reserve in Patients With Stable Angina Pectoris or Acute Coronary Syndrome) randomized clinical trials was investigated. Patients were stratified according to revascularization decision making on the basis of iFR or FFR and to clinical presentation (SAP or ACS). The primary endpoint was major adverse cardiac events (MACE), defined as the composite of all-cause death, nonfatal myocardial infarction, or unplanned revascularization at 1 year.Results
Coronary revascularization was deferred in 2,130 patients. Deferral was performed in 1,117 patients (50%) in the iFR group and 1,013 patients (45%) in the FFR group (p < 0.01). At 1 year, the MACE rate in the deferred population was similar between the iFR and FFR groups (4.12% vs. 4.05%; fully adjusted hazard ratio: 1.13; 95% confidence interval: 0.72 to 1.79; p = 0.60). A clinical presentation with ACS was associated with a higher MACE rate compared with SAP in deferred patients (5.91% vs. 3.64% in ACS and SAP, respectively; fully adjusted hazard ratio: 0.61 in favor of SAP; 95% confidence interval: 0.38 to 0.99; p = 0.04).Conclusions
Overall, deferral of revascularization is equally safe with both iFR and FFR, with a low MACE rate of about 4%. Lesions were more frequently deferred when iFR was used to assess physiological significance. In deferred patients presenting with ACS, the event rate was significantly increased compared with SAP at 1 year. 相似文献14.

Background
Contrasting evidence exists on the comparative efficacy and safety of bivalirudin and unfractionated heparin (UFH) in relation to the planned use of glycoprotein IIb/IIIa inhibitors (GPIs).Objectives
This study assessed the efficacy and safety of bivalirudin compared with UFH with or without GPIs in patients with acute coronary syndrome (ACS) who underwent invasive management.Methods
In the MATRIX (Minimizing Adverse Haemorrhagic Events by Transradial Access Site and Systemic Implementation of AngioX) program, 7,213 patients were randomly assigned to receive either bivalirudin or UFH with or without GPIs at discretion of the operator. The 30-day coprimary outcomes were major adverse cardiovascular events (MACEs) (a composite of death, myocardial infarction, or stroke), and net adverse clinical events (NACEs) (a composite of MACEs or major bleeding).Results
Among 3,603 patients assigned to receive UFH, 781 (21.7%) underwent planned treatment with GPI before coronary intervention. Bailout use of GPIs was similar between the bivalirudin and UFH groups (4.5% and 5.4%) (p = 0.11). At 30 days, the 2 coprimary endpoints of MACEs and NACEs, as well as individual endpoints of mortality, myocardial infarction, stent thrombosis or stroke did not differ among the 3 groups after adjustment. Compared with the UFH and UFH+GPI groups, bivalirudin reduced bleeding, mainly the most severe bleeds, including fatal and nonaccess site?related events, as well as transfusion rates and the need for surgical access site repair. These findings were not influenced by the administered intraprocedural dose of UFH and were confirmed at multiple sensitivity analyses, including the randomly allocated access site.Conclusions
In patients with ACS, the rates of MACEs and NACEs were not significantly lower with bivalirudin than with UFH, irrespective of planned GPI use. However, bivalirudin significantly reduced bleeding complications, mainly those not related to access site, irrespective of planned use of GPIs.

BackgroundCholesterol reduction with proprotein convertase subtilisin-kexin type 9 inhibitors reduces ischemic events; however, the cost-effectiveness in statin-treated patients with recent acute coronary syndrome remains uncertain.ObjectivesThis study sought to determine whether further cholesterol reduction with alirocumab would be cost-effective in patients with a recent acute coronary syndrome on optimal statin therapy.MethodsA cost-effectiveness model leveraging patient-level data from ODYSSEY OUTCOMES (Evaluation of Cardiovascular Outcomes After an Acute Coronary Syndrome During Treatment With Alirocumab) was developed to estimate costs and outcomes over a lifetime horizon. Patients (n = 18,924) had a recent acute coronary syndrome and were on high-intensity or maximum-tolerated statin therapy, with a baseline low-density lipoprotein cholesterol (LDL-C) level ≥70 mg/dl, non–high-density lipoprotein cholesterol ≥100 mg/dl, or apolipoprotein B ≥80 mg/l. Alirocumab 75 mg or placebo was administered subcutaneously every 2 weeks. Alirocumab was blindly titrated to 150 mg if LDL-C remained ≥50 mg/dl or switched to placebo if 2 consecutive LDL-C levels were <15 mg/dl. Incremental cost per quality-adjusted life-year (QALY) was determined with the addition of alirocumab versus placebo and, based on clinical efficacy findings from the trial, was stratified by baseline LDL-C levels ≥100 mg/dl and <100 mg/dl.ResultsAcross the overall population recruited to the ODYSSEY OUTCOMES trial, using an annual treatment cost of US$5,850, the mean overall incremental cost-effectiveness ratio was US$92,200 per QALY (base case). The cost was US$41,800 per QALY in patients with baseline LDL-C ≥100 mg/dl, whereas in those with LDL-C <100 mg/dl the cost per QALY was US$299,400. Among patients with LDL-C ≥100 mg/dl, incremental cost-effectiveness ratios remained below US$100,000 per QALY across a wide variety of sensitivity analyses.ConclusionsIn patients with a recent acute coronary syndrome on optimal statin therapy, alirocumab improves cardiovascular outcomes at costs considered intermediate value, with good value in patients with baseline LDL-C ≥100 mg/dl but less economic value with LDL-C <100 mg/dl.

Objectives
The aim of the present study was to assess the effect of early statin therapy on fibrous-cap thickness in coronary plaques of patients with acute coronary syndrome (ACS) by using optical coherence tomography.Background
Statins can contribute to the stabilization of coronary plaques.Methods
This is a prospective, randomized, active-controlled, single-center study. Patients with ACS and untreated dyslipidemia were enrolled and randomly allocated (ratio 1:1) to either the early statin group (received pitavastatin 4 mg/day from baseline) or the late statin group (received pitavastatin 4 mg/day from 3 weeks after the baseline). Optical coherence tomography was performed at baseline, 3-week, and 36-week follow-up to assess nonculprit coronary plaques in 53 patients.Results
Between baseline and 3-week follow-up, fibrous-cap thickness increased in the early statin group (140 μm [interquartile range (IQR):120 to 170 μm] to 160 μm [IQR: 130 to 190 μm]; p = 0.017), but decreased in the late statin group (135 μm [IQR: 110 to 183 μm] to 130 μm [IQR: 108 to 160 μm]; p = 0.020). The percentage of increase in fibrous-cap thickness between baseline and 3-week follow-up was significantly greater in the early statin group compared with the late statin group (8.3% [IQR: 0.0% to 21.4%] vs. ?5.8% [IQR: ?16.0% to 0.0%]; p < 0.001). Between baseline and 36-week follow-up, fibrous-cap thickness increased comparably in the 2 groups.Conclusions
Early therapy with pitavastatin 4 mg/day for patients with ACS provided an increase in fibrous-cap thickness in coronary plaques during the first 3 weeks of follow-up and a further increase during 36 weeks of follow-up.

ObjectivesThis study sought to determine the effect of radial access on outcomes in women undergoing percutaneous coronary intervention (PCI) using a registry-based randomized trial.BackgroundWomen are at increased risk of bleeding and vascular complications after PCI. The role of radial access in women is unclear.MethodsWomen undergoing cardiac catheterization or PCI were randomized to radial or femoral arterial access. Data from the CathPCI Registry and trial-specific data were merged into a final study database. The primary efficacy endpoint was Bleeding Academic Research Consortium type 2, 3, or 5 bleeding or vascular complications requiring intervention. The primary feasibility endpoint was access site crossover. The primary analysis cohort was the subgroup undergoing PCI; sensitivity analyses were conducted in the total randomized population.ResultsThe trial was stopped early for a lower than expected event rate. A total of 1,787 women (691 undergoing PCI) were randomized at 60 sites. There was no significant difference in the primary efficacy endpoint between radial or femoral access among women undergoing PCI (radial 1.2% vs. 2.9% femoral, odds ratio [OR]: 0.39; 95% confidence interval [CI]: 0.12 to 1.27); among women undergoing cardiac catheterization or PCI, radial access significantly reduced bleeding and vascular complications (0.6% vs. 1.7%; OR: 0.32; 95% CI: 0.12 to 0.90). Access site crossover was significantly higher among women assigned to radial access (PCI cohort: 6.1% vs. 1.7%; OR: 3.65; 95% CI: 1.45 to 9.17); total randomized cohort: (6.7% vs. 1.9%; OR: 3.70; 95% CI: 2.14 to 6.40). More women preferred radial access.ConclusionsIn this pragmatic trial, which was terminated early, the radial approach did not significantly reduce bleeding or vascular complications in women undergoing PCI. Access site crossover occurred more often in women assigned to radial access. (SAFE-PCI for Women; NCT01406236) 相似文献
