Background

The functional SYNTAX score (FSS) has been shown to improve the discrimination for major adverse cardiac events compared with the anatomic SYNTAX score (SS) while reducing interobserver variability. However, evidence supporting the noninvasive FSS in patients with multivessel coronary artery disease (CAD) is scarce.

Objectives

The purpose of this study was to assess the feasibility of and validate the noninvasive FSS derived from coronary computed tomography angiography (CTA) with fractional flow reserve (FFRCT) in patients with 3-vessel CAD.

Methods

The CTA-SS was calculated in patients with 3-vessel CAD included in the SYNTAX II (SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery II) study. The noninvasive FSS was determined by including only ischemia-producing lesions (FFRCT ≤0.80). SS derived from different imaging modalities were compared using the Bland-Altman and Passing-Bablok method, and the agreement on the SS tertiles was investigated with Cohen’s Kappa. The risk reclassification was compared between the noninvasive and invasive physiological assessment, and the diagnostic accuracy of FFRCT was assessed by the area under the receiver-operating characteristic curve using instantaneous wave-free ratio as a reference.

Results

The CTA-SS was feasible in 86% of patients (66 of 77), whereas the noninvasive FSS was feasible in 80% (53 of 66). The anatomic SS was overestimated by CTA compared with conventional angiography (27.6 ± 6.4 vs. 25.3 ± 6.9; p < 0.0001) whereas the calculation of the FSS yielded similar results between the noninvasive and invasive imaging modalities (21.6 ± 7.8 vs. 21.2 ± 8.8; p = 0.589). The noninvasive FSS reclassified 30% of patients from the high- and intermediate-SS tertiles to the low-risk tertile, whereas invasive FSS reclassified 23% of patients from the high- and intermediate-SS tertiles to the low-risk tertile. The agreement on the classic SS tertiles based on Kappa statistics was slight for the anatomic SS (Kappa = 0.19) and fair for the FSS (Kappa = 0.32). The diagnostic accuracy of FFRCT to detect functional significant stenosis based on an instantaneous wave-free ratio ≤0.89 revealed an area under the receiver-operating characteristics curve of 0.85 (95% CI: 0.79 to 0.90) with a sensitivity of 95% (95% CI: 89% to 98%), specificity of 61% (95% CI: 48% to 73%), positive predictive value of 81% (95% CI: 76% to 86%), and negative predictive value of 87% (95% CI: 74% to 94%).

Conclusions

Calculation of the noninvasive FSS is feasible and yielded similar results to those obtained with invasive pressure-wire assessment. The agreement on the SYNTAX score tertile classification improved with the inclusion of the functional component from slight to fair agreement. FFRCT has good accuracy in detecting functionally significant lesions in patients with 3-vessel CAD.

Background

There is limited information on the incidence and prognostic impact of new-onset atrial fibrillation (NOAF) following percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) for left main coronary artery disease (LMCAD).

Objectives

This study sought to determine the incidence of NOAF following PCI and CABG for LMCAD and its effect on 3-year cardiovascular outcomes.

Methods

In the EXCEL (Evaluation of XIENCE Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial, 1,905 patients with LMCAD and low or intermediate SYNTAX scores were randomized to PCI with everolimus-eluting stents versus CABG. Outcomes were analyzed according to the development of NOAF during the initial hospitalization following revascularization.

Results

Among 1,812 patients without atrial fibrillation on presentation, NOAF developed at a mean of 2.7 ± 2.5 days after revascularization in 162 patients (8.9%), including 161 of 893 (18.0%) CABG-treated patients and 1 of 919 (0.1%) PCI-treated patients (p < 0.0001). Older age, greater body mass index, and reduced left ventricular ejection fraction were independent predictors of NOAF in patients undergoing CABG. Patients with versus without NOAF had a significantly longer duration of hospitalization, were more likely to be discharged on anticoagulant therapy, and had an increased 30-day rate of Thrombolysis In Myocardial Infarction major or minor bleeding (14.2% vs. 5.5%; p < 0.0001). By multivariable analysis, NOAF after CABG was an independent predictor of 3-year stroke (6.6% vs. 2.4%; adjusted hazard ratio [HR]: 4.19; 95% confidence interval [CI]: 1.74 to 10.11; p = 0.001), death (11.4% vs. 4.3%; adjusted HR: 3.02; 95% CI: 1.60 to 5.70; p = 0.0006), and the primary composite endpoint of death, MI, or stroke (22.6% vs. 12.8%; adjusted HR: 2.13; 95% CI: 1.39 to 3.25; p = 0.0004).

Conclusions

In patients with LMCAD undergoing revascularization in the EXCEL trial, NOAF was common after CABG but extremely rare after PCI. The development of NOAF was strongly associated with subsequent death and stroke in CABG-treated patients. Further studies are warranted to determine whether prophylactic strategies to prevent or treat atrial fibrillation may improve prognosis in patients with LMCAD who are undergoing CABG.

Objectives

This study sought to assess whether transradial access (TRA) compared with transfemoral access (TFA) is associated with consistent outcomes in male and female patients with acute coronary syndrome undergoing invasive management.

Background

There are limited and contrasting data about sex disparities for the safety and efficacy of TRA versus TFA for coronary intervention.

Methods

In the MATRIX (Minimizing Adverse Haemorrhagic Events by TRansradial Access Site and Systemic Implementation of angioX) program, 8,404 patients were randomized to TRA or TFA. The 30-day coprimary outcomes were major adverse cardiovascular and cerebrovascular events (MACCE), defined as death, myocardial infarction, or stroke, and net adverse clinical events (NACE), defined as MACCE or major bleeding.

Results

Among 8,404 patients, 2,232 (26.6%) were women and 6,172 (73.4%) were men. MACCE and NACE were not significantly different between men and women after adjustment, but women had higher risk of access site bleeding (male vs. female rate ratio [RR]: 0.64; p = 0.0016), severe bleeding (RR: 0.17; p = 0.0012), and transfusion (RR: 0.56; p = 0.0089). When comparing radial versus femoral, there was no significant interaction for MACCE and NACE stratified by sex (pint = 0.15 and 0.18, respectively), although for both coprimary endpoints the benefit with TRA was relatively greater in women (RR: 0.73; p = 0.019; and RR: 0.73; p = 0.012, respectively). Similarly, there was no significant interaction between male and female patients for the individual endpoints of all-cause death (pint = 0.79), myocardial infarction (pint = 0.25), stroke (pint = 0.18), and Bleeding Academic Research Consortium type 3 or 5 (pint = 0.45).

Conclusions

Women showed a higher risk of severe bleeding and access site complications, and radial access was an effective method to reduce these complications as well as composite ischemic and ischemic or bleeding endpoints.  相似文献

Thrombolysis with conventional thrombolytic agents followed by percutaneous coronary intervention (PCI) had no impact on the treatment of acute myocardial infarction (AMI). However, the development of mutant type plasminogen activator (mt‐PA) has prompted us to reassess the combination of thrombolysis and PCI. Monteplase (Eisai, Co. Ltd., Tokyo, Japan) is a newly developed mt‐PA that can be administrated as a single intravenous bolus injection. We initiated a clinical trial [Combining Monteplase with Angioplasty (COMA)] to evaluate the effectiveness of monteplase followed by PCI. The AMI patients were randomly assigned to receive PCI following pretreatment with a single bolus intravenous injection of monteplase or direct PCI without monteplase. The initial coronary angiography prior to PCI showed that 36.2% of patients in the monteplase group achieved Thrombolysis in Myocardial Infarction (TIMI) 3 flow in the infarct‐related artery, compared with in only 7.9% of patients in the direct PCI group (P < 0.0001). During 24 months following PCI, major cardiac events occurred in 27.7% of patients in the monteplase + PCI group, and in 46.7% of patients in the direct PCI group without monteplase (P < 0.05). Thus, the ideal strategy for the treatment of AMI is the administration of monteplase upon arrival at a community hospital with a prompt transfer to a tertiary center for PCI.  相似文献

Objectives

The authors sought to compare outcomes of patients with myocardial infarction and cardiogenic shock (CS) treated with percutaneous coronary intervention (PCI) with or without intra-aortic balloon pump (IABP) support according to final epicardial flow in the infarct-related artery.

Background

A routine use of IABP is contraindicated in patients with myocardial infarction and CS. There are no data regarding the subpopulation of patients who may benefit from such support besides patients with mechanical complications of myocardial infarction.

Methods

Prospective nationwide registry data of patients with myocardial infarction and CS treated with PCI between 2003 and 2014 were analyzed. Patients were initially stratified into 2 groups according to final infarct-related artery Thrombolysis In Myocardial Infarction (TIMI) flow grade after PCI: those with successful primary PCI (TIMI flow grades 2 or 3) and those with unsuccessful primary PCI (TIMI flow grades 0 or 1). Outcomes of patients with or without IABP treatment in each group were analyzed and compared.

Results

In the unsuccessful PCI group, patients in whom IABP was applied had lower in-hospital, 30-day, and 12-month mortality. IABP support in this group of patients was an independent predictor of lower 30-day mortality (hazard ratio [HR]: 0.72; 95% confidence interval [CI]: 0.59 to 0.89; p = 0.002). Conversely, in patients with successful PCI, IABP was an independent predictor of higher 30-day mortality (HR: 1.18; 95% CI: 1.08 to 1.30; p = 0.0004).

Conclusions

IABP is associated with a lower risk of 30-day mortality in patients with myocardial infarction complicated by CS, in whom primary PCI was unsuccessful.  相似文献
