- 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. (C) 2018 The Authors.

- OBJECTIVES The aim of this study was to describe current practice regarding completeness of revascularization in patients with multivessel disease undergoing percutaneous coronary intervention (PCI) and to investigate the association of incomplete revascularization (IR) with death, repeat revascularization, and myocardial infarction (MI) in a large nationwide registry. BACKGROUND The benefits of multivessel PCI are controversial. METHODS Between 2006 and 2010 we identified 23,342 patients with multivessel disease in the SCAAR (Swedish Coronary Angiography and Angioplasty Registry) and merged data with official Swedish health data registries. IR was defined as any nontreated significant (60%) stenosis in a coronary artery supplying > 10% of the myocardium. RESULTS Patients with IR (n = 15,165) were older, had more extensive coronary disease, and more often had ST-segment elevation MI at presentation than those with complete revascularization (CR) (n = 8,177). All-cause 1-year mortality, MI, and repeat revascularization were higher in IR than CR: 7.1% versus 3.8%, 10.4% versus 6.0%, and 20.5% versus 8.5%, respectively. Propensity score methodology was used in the adjusted analyses. Adjusted hazard ratio (HR) for the composite of death, MI, or repeat revascularization at 1 year was higher in IR than CR: 2.12 (95% confidence interval [CI]: 1.98 to 2.28; p < 0.0001). Adjusted HR for death and the combination of death/MI were 1.29 (95% CI: 1.12 to 1.49; p = 0.0005) and 1.42 (95% CI: 1.30 to 1.56; p < 0.0001), respectively. CONCLUSIONS Incomplete revascularization at the time of hospital discharge in patients with multivessel disease undergoing PCI is associated with a high risk of recurrent 1-year adverse cardiac events.

- Objectives This study sought to study the second-generation everolimus-eluting stent (EES) as compared with first-generation sirolimus-eluting (SES) and paclitaxel-eluting stents (PES) in diabetes mellitus (DM) patients. Background There are limited data available comparing clinical outcomes in this setting with EES and SES, whereas studies comparing EES with PES are not powered for low-frequency endpoints. Methods All DM patients treated with EES, PES, or SES from January 18, 2007, to July 29, 2011, from the SCAAR (Swedish Coronary Angiography and Angioplasty Registery) were included. The EES was compared with SES or PES for the primary composite endpoint of clinically driven detected restenosis, definite stent thrombosis (ST), and all-cause mortality. Results In 4,751 percutaneous coronary intervention-treated DM patients, 8,134 stents were implanted (EES = 3,928, PES = 2,836, SES = 1,370). The EES was associated with significantly lower event rates compared with SES (SES vs. EES hazard ratio [HR]: 1.99; 95% confidence interval (CI): 1.19 to 3.08). The same was observed when compared with PES (PES vs. EES HR: 1.33; 95% CI: 0.93 to 1.91) but did not reach statistical significance. These results were mainly driven by lower incidence of ST (SES vs. EES HR: 2.87; 95% CI: 1.08 to 7.61; PES vs. EES HR: 1.74, 95% CI: 0.82 to 3.71) and mortality (SES vs. EES HR: 2.02; 95% CI: 1.03 to 3.98; PES vs. EES HR: 1.69; 95% CI: 1.06 to 2.72). No significant differences in restenosis rates were observed between EES and SES or PES (SES vs. EES HR: 1.26; 95% CI: 0.77 to 2.08; PES vs. EES HR: 1.05; 95% CI: 0.71 to 1.55). Conclusions In all-comer DM patients the use of EES was associated with improved outcomes compared with SES and PES mainly driven by lower rates of ST and mortality. These results suggest better safety rather than efficacy with EES when compared with SES or PES. (J Am Coll Cardiol Intv 2012;5:1141-9) (C) 2012 by the American College of DM

- The occurrence of acute kidney injury (AKI) among patients with acute coronary syndrome (ACS) undergoing invasive management is associated with worse outcomes. However, the prognostic implications of transient or in-hospital persistent AKI may differ.The aim of this study was to evaluate the prognostic implications of transient or in-hospital persistent AKI in patients with ACS.In the MATRIX (Minimizing Adverse Haemorrhagic Events by Transradial Access Site and Systemic Implementation of Angiox) trial, 203 subjects were excluded because of incomplete information or end-stage renal disease, with a study population of 8,201 patients. Transient and persistent AKI were defined as renal dysfunction no longer or still fulfilling the AKI criteria (>0.5mg/dL or a relative >25% increase in creatinine) at discharge, respectively. Thirty-day coprimary outcomes were the out-of-hospital composite of death, myocardial infarction, or stroke (major adverse cardiovascular events [MACE]) and net adverse cardiovascular events (NACE), defined as the composite of MACE or Bleeding Academic Research Consortium type 3 or 5 bleeding.Persistent and transient AKI occurred in 750 (9.1%) and 587 (7.2%) subjects, respectively. After multivariable adjustment, compared with patients without AKI, the risk for 30-day coprimary outcomes was higher in patients with persistent AKI (MACE: adjusted HR: 2.32; 95%CI: 1.48-3.64; P< 0.001; NACE: adjusted HR: 2.29; 95%CI: 1.48-3.52; P< 0.001), driven mainly by all-cause mortality (adjusted HR: 3.43; 95%CI: 2.03-5.82; P< 0.001), whereas transient AKI was not associated with higher rates of MACE or NACE. Results remained consistent when implementing the KDIGO (Kidney Disease Improving Global Outcomes) criteria.Among patients with ACS undergoing invasive management, in-hospital persistent but not transient AKI was associated with higher risk for 30-day MACE and NACE.

- Objectives: In this substudy of the DETO2X-AMI (An Efficacy and Outcome Study of Supplemental Oxygen Treatment in Patients With Suspected Myocardial Infarction) trial, the authors aimed to assess the analgesic effect of moderate-flow oxygen supplementation in patients with suspected acute myocardial infarction (AMI) treated with percutaneous coronary intervention (PCI) and to study the effect of oxygen supplementation on the use of opiates and sedatives during PCI. Background: Routine oxygen in normoxemic patients with AMI does not provide clinical benefit. However, oxygen may relieve ischemic pain. Methods: Patients were randomly allocated to oxygen or ambient air according to the main study protocol. After PCI, peak level of pain during PCI was measured by the Visual Analogue Scale. The total amount of opiates and sedatives was reported. Results: A total of 622 patients were enrolled: 330 in the oxygen group and 292 in the ambient air group. There was no significant difference in peak level of pain (oxygen 4.0 [1.0 to 6.0] vs. air 3.0 [0.6 to 6.0]; p = 0.37), use of opiates (mg) (oxygen 0.0 [0.0 to 3.0] vs. air 0.0 [0.0 to 3.0]; p = 0.31), or use of sedatives between the groups (median [interquartile range]) (oxygen 2.5 [0.0 to 2.5] vs. air 2.5 [0.0 to 2.5]; p = 0.74). Conclusions: In the present study, the authors did not find any analgesic effect of routine oxygen as compared with ambient air, and no differences in the use of sedatives and opiates during PCI. Our results indicate that moderate-flow oxygen supplementation does not relieve pain in normoxemic patients with suspected AMI undergoing treatment with PCI and should thus not be used for this purpose.

- OBJECTIVES This study sought to compare interrupted and uninterrupted oral anticoagulant therapy (I-OAC vs. U-OAC) in patients on OAC undergoing percutaneous coronary intervention. BACKGROUND There is a paucity of data regarding the optimal peri-procedural management of OAC-treated patients. METHODS In the SWEDEHEART registry, all patients on OAC who were admitted acutely and underwent percutaneous coronary intervention or coronary angiography with a diagnostic procedure, from 2005 to 2017, were included. Outcomes were major adverse cardiac and cerebrovascular events (MACCE; death, myocardial infarction, or stroke) and bleeds at 120 days. Propensity score was used to adjust for the nonrandomized treatment selection. RESULTS The study included 6,485 patients: 3,322 in the I-OAC group and 3,163 in the U-OAC group. The cumulative incidence of MACCE was 8.2% (269 events) versus 8.2% (254 events) in the I-OAC and the U-OAC groups, respectively. The adjusted risk for MACCE did not differ between the groups (I-OAC vs. U-OAC hazard ratio: 0.89; 95% confidence interval: 0.71 to 1.12). Similarly, no difference was found in the risk for MACCE or bleeds (12.6% vs. 12.9%, adjusted hazard ratio: 0.87; 95% confidence interval: 0.70 to 1.07). The risk for major or minor in-hospital bleeds did not differ between the groups. However, U-OAC was associated with a significantly shorter duration of hospitalization: 4 (3 to 7) days versus 5 (3 to 8) days; p < 0.01. CONCLUSIONS I-OAC and U-OAC were associated with equivalent risk for MACCE and bleeding complications. An U-OAC strategy was associated with shorter length of hospitalization. These data support U-OAC as the preferable strategy in patients on OAC undergoing coronary intervention. (c) 2021 by the American College of Cardiology Foundation.

- Objectives The aim of this study was to determine the prognostic impact of chronic total occlusion (CTO) on long-term mortality in a large prospective cohort. Background CTO is present in many patients with coronary artery disease and is difficult to treat with percutaneous coronary intervention. Methods The study population consisted of all consecutive patients who underwent coronary angiography in Sweden between January 1, 2005 and January 1, 2012, who were registered in SCAAR (Swedish Coronary Angiography and Angioplasty Registry). The patient population was heterogeneous with regard to indication for angiography (stable angina, ST-segment elevation myocardial infarction [STEMI], unstable angina or non-STEMI, and other) and treatment options. The long-term mortality rates of patients with and without CTO were compared by using shared frailty Cox proportional hazards regression adjusted for confounders. Tests were conducted for interactions between CTO and several pre-specified characteristics: indication for angiography and percutaneous coronary intervention (stable angina, STEMI, unstable angina or non-STEMI, and other), severity of coronary artery disease (1-, 2-, and 3-vessel and/or left main coronary artery disease), age, sex, and diabetes. Results During the study period, 14,441 patients with CTO and 75,431 patients without CTO were registered in SCAAR. CTO was associated with higher mortality (hazard ratio: 1.29; 95% confidence interval: 1.22 to 1.37; p < 0.001). In subgroup analyses, the risk attributable to CTO was lowest in patients with stable angina and highest in those with STEMI. In addition, CTO was associated with highest risk in patients under 60 years of age and with lowest risk in octogenarians. There was no interaction between CTO and either diabetes or sex, suggesting an equally adverse effect in both groups. Conclusions In this large prospective observational study of patients with coronary artery disease, CTO was associated with increased mortality. This association was most prominent in younger patients and in those with acute coronary syndromes.
