Skin Autofluorescence and Clinical Outcomes in Patients with Coronary Artery Disease. J Atheroscler Thromb 2024; 31:316-325. [PMID: 37743505 PMCID: PMC10918030 DOI: 10.5551/jat.64293] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Accepted: 08/02/2023] [Indexed: 09/26/2023] Open
Abstract
AIM This study aimed to investigate whether skin autofluorescence (SAF) is associated with clinical outcomes in patients with coronary artery disease. Advanced glycation end products (AGE) play a crucial role in atherosclerosis. Accumulation of AGE can be measured non-invasively by SAF. METHODS We performed a single-center prospective study of 896 patients with coronary artery disease treated with percutaneous coronary intervention (PCI) between January 2014 and December 2015. SAF was measured before the PCI procedure. The primary endpoint was patient-oriented composite endpoints (POCE) defined as a composite of all-cause death, any myocardial infarction, any stroke, and any revascularization. RESULTS Patients were significantly older and suffered higher rates of chronic kidney disease (CKD) in the high SAF group. A higher SAF was associated with an increased risk for POCE (HR 1.43; 95% CI 1.19-1.71, p<0.001) that was mainly driven by any coronary revascularization (HR 1.33; 95% CI 1.08-1.65, p=0.01) including target lesion revascularization (HR 1.41; 95% CI 1.02-1.94, p=0.04). The higher SAF group also experienced worse outcomes in stroke (HR 2.08; 95% CI 1.38-3.15, p=0.001). Multivariate analyses indicated that SAF was an independent predictor of POCE (HR 1.36; 95% CI 1.13-1.63, p=0.001). CONCLUSIONS SAF as a measure of AGE deposition is independently associated with cardiovascular events amongst patients with coronary artery disease treated with PCI. SAF also predicts the incidence of restenosis and stroke.

The estimation of coronary artery calcium thickness by computed tomography angiography based on optical coherence tomography measurements. Heart Vessels 2023; 38:1305-1317. [PMID: 37422802 DOI: 10.1007/s00380-023-02286-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Accepted: 06/29/2023] [Indexed: 07/11/2023]
Abstract
Optical coherence tomography (OCT) is recommended to be the most appropriate modality in assessing calcium thickness, however, it has limitations associated with infrared attenuation. Although coronary computed tomography angiography (CCTA) detects calcification, it has low resolution and hence not recommended to measure the calcium size. The aim of this study was to devise a simple algorithm to estimate calcium thickness based on the CCTA image. A total of 68 patients who had CCTA for suspected coronary artery disease and subsequently went on to have OCT were included in the study. 238 lesions of them divided into derivation and validation dataset at 2:1 ratio (47 patients with 159 lesions and 21 with 79, respectively) were analyzed. A new method was developed to estimate calcium thickness from the maximum CT density within the calcification and compared with calcium thickness measured by OCT. Maximum Calcium density and measured calcium-border CT density had a good correlation with a linear equation of y = 0.58x + 201 (r = 0.892, 95% CI 0.855-0.919, p < 0.001). The estimated calcium thickness derived from this equation showed strong agreement with measured calcium thickness in validation and derivation dataset (r2 = 0.481 and 0.527, 95% CI 0.609-0.842 and 0.497-0.782, p < 0.001 in both, respectively), more accurate than the estimation by full width at half maximum and inflection point method. In conclusion, this novel method provided the estimation of calcium thickness more accurately than conventional methods.

Association between cancer history and second-generation drug-eluting stent thrombosis: insights from the REAL-ST registry. Thromb J 2023; 21:60. [PMID: 37226249 DOI: 10.1186/s12959-023-00503-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Accepted: 05/17/2023] [Indexed: 05/26/2023] Open
Abstract
BACKGROUND Cancer-associated thrombosis is a frequent complication of cancer; however, little evidence is available regarding the association between cancer history and coronary artery stent thrombosis (ST). We aimed to investigate the relationship between cancer history and second-generation drug-eluting stent thrombosis (G2-ST). METHODS From the REAL-ST (Retrospective Multicenter Registry of ST After First- and Second-Generation Drug-Eluting Stent Implantation) registry, this study evaluated 1265 patients (G2- ST cases, n = 253; controls, n = 1012) with cancer-related information available. RESULTS The prevalence of patients with cancer history was higher (12.3% vs. 8.5%, p = 0.065), and that of currently diagnosed and currently treated cancer was significantly higher in ST cases than controls (3.6% vs. 1.4%, p = 0.021; 3.2% vs. 1.3%, p = 0.037, respectively). Multivariable logistic regression analysis revealed that cancer history was associated with late ST (odds ratio [OR]: 2.80, 95% confidence intervals [CI]: 0.92-8.55, p = 0.071) and very late ST (OR: 2.40, 95% CI: 1.02-5.65, p = 0.046), but not with early ST (OR: 1.01, 95% CI: 0.51-2.00, p = 0.97). During the median follow-up period of 872 days after the index ST events, patients with cancer history showed a higher mortality than those without, among both ST cases (hazard ratio [HR]: 1.93, 95% CI: 1.06-3.51, p = 0.031) and controls (HR: 1.93, 95% CI: 1.09-3.40, p = 0.023). CONCLUSION A post hoc analysis of REAL-ST registry revealed that patients with G2-ST had a higher prevalence of currently diagnosed and currently treated cancer. Notably, cancer history was associated with the occurrence of late and very late ST, but not with early ST.

Abstract
Objectives. The impact of chronic kidney disease (CKD) on clinical outcomes after percutaneous coronary intervention (PCI) for unprotected left main distal bifurcation lesions (ULMD) is not fully understood in current generation drug eluting stent (cDES) era. We assessed clinical outcomes after PCI using cDES for ULMD according to CKD severity based on estimated glomerular filtration rate (eGFR). Design. We identified 720 consecutive patients who underwent PCI using cDES for ULMD at three high volume centers between January 2005 and December 2015. We divided those patients to the following five groups according to eGFR. Each group was defined as follows: no CKD (60 mL/min/1.73 m2 ≤ eGFR), mild CKD (45 ≤ eGFR < 60 mL/min/1.73 m2), moderate CKD (30 ≤ eGFR < 45 mL/min/1.73 m2), severe CKD (15 ≤ eGFR < 30 mL/min/1.73 m2) and hemodialysis (HD). The primary endpoint was target lesion failure (TLF) at 3 years. TLF was defined as a composite of cardiac death, target lesion revascularization (TLR) and myocardial infarction (MI). Results. TLF occurred more frequently in severe CKD and HD group compared with other three groups. Conclusions. The patients who have severe CKD or are on HD, were extremely associated with worse clinical outcomes after PCI for ULMD even with cDES.

Abstract
BACKGROUND The relationship between in-stent calcified nodules (IS-CN) and second-generation drug-eluting stent (G2-DES) stent thrombosis (ST) remains uncertain. AIMS We aimed to evaluate the prevalence, clinical demographic and long-term clinical outcomes after G2-DES ST with IS-CN. METHODS The prespecified substudy of the REAL-ST registry (a retrospective, multicentre registry of patients with definite ST after first- and G2-DES implantation) enrolled patients who experienced definite G2-DES ST and who underwent pre-intervention intravascular ultrasound imaging at index ST events. RESULTS IS-CN was observed in 15 out of 118 (13%) definite G2-DES ST cases. The multiple logistic regression model demonstrated that haemodialysis (odds ratio [OR] 12.27, 95% confidence interval [CI]: 1.56-94.54; p=0.02), proximal or mid-right coronary artery lesions (OR 12.79, 95% CI: 1.78-92.13; p=0.01) and severe calcification (OR 13.01, 95% CI: 1.18-142.94; p=0.04) were independently associated with ST with IS-CN. The cumulative 5-year incidence of target lesion revascularisation (TLR) after ST was significantly higher in the IS-CN group than in the non-IS-CN group (p=0.02). Independent predictors of TLR after the index ST events were female sex (hazard ratio [HR] 3.05, 95% CI: 1.20-7.74; p=0.02), diabetes mellitus (HR 3.26, 95% CI: 1.26-8.41; p=0.01) and IS-CN (HR 3.07, 95% CI: 1.16-8.14; p=0.02). CONCLUSIONS IS-CN may be one of the underlying mechanisms of G2-DES ST. Notably, IS-CN was associated with a higher TLR rate after the index ST events, suggesting the need for careful clinical follow-up of ST patients with IS-CN.

Abstract
Vascular inflammation, lipid metabolism, and thrombogenicity play a key role not only in atherogenesis but also in the development of acute coronary syndromes. Biomarkers associated with coronary high-risk plaques defined according to intravascular imaging have not been systematically studied. A total of 69 patients with coronary artery disease who underwent both optical coherence tomography and intravascular ultrasound imaging, and who provided blood specimens were included. Comprehensive biomarkers for inflammation, lipid, and coagulation were analyzed. Composite models sought biomarker patterns associated with thin-cap fibroatheroma (TCFA) and "high-risk plaques" (TCFA and large plaque burden). Two different composite models were developed for TCFA, based on the finding that high sensitivity C-reactive protein (hsCRP), plasminogen activator inhibitor-1, fibrinogen, IL-6, homocysteine and amyloid A levels were elevated, and high-density lipoprotein cholesterol (HDL) and bile acid levels were decreased in these patients. Both composite models were highly accurate for detecting patients with TCFA (area under curve [AUC]: 0.883 in model-A and 0.875 in model-B, both p < 0.001). In addition, creatinine, hsCRP, fibrinogen, tumor necrosis factor-α, IL-6, homocysteine, amyloid A, HDL, prothrombin, and bile acid were useful for detecting patients with "high-risk plaques". Two composite models were highly accurate for detection of patients with "high-risk plaques" (AUC: 0.925 in model-A and 0.947 in model-B, both p < 0.001). Biomarkers useful for detection of patients with high-risk coronary plaques defined according to intravascular imaging have been identified. These biomarkers may be useful to risk stratify patients and to develop targeted therapy.Clinical Trial Registration https://www.umin.ac.jp/ctr/ , UMIN000041692. Biomarkers and high-risk plaques hsCRP, PAI-1, fibrinogen, IL-6, homocysteine, amyloid A, HDL, and bile acid were useful for detecting patients with TCFA. hsCRP, fibrinogen, IL-6, homocysteine, amyloid A, creatinine, TNFα, HDL, prothrombin, and bile acid were useful for detecting patients with "high-risk plaques" (plaque which has both TCFA and large plaque burden).

Abstract
Background The relationship between gut microbiota and in vivo coronary plaque characteristics has not been reported. This study was conducted to investigate the relationship between gut microbiota and coronary plaque characteristics in patients with coronary artery disease. Methods and Results Patients who underwent both optical coherence tomography and intravascular ultrasound imaging and provided stool and blood specimens were included. The composition of gut microbiota was evaluated using 16S rRNA sequencing. A total of 55 patients were included. At the genus level, 2 bacteria were associated with the presence of thin-cap fibroatheroma, and 9 bacteria were associated with smaller fibrous cap thickness. Among them, some bacteria had significant associations with inflammatory/prothrombotic biomarkers. Dysgonomonas had a positive correlation with interleukin-6, Paraprevotella had a positive correlation with fibrinogen and negative correlation with high-density lipoprotein cholesterol, Succinatimonas had positive correlations with fibrinogen and homocysteine, and Bacillus had positive correlations with fibrinogen and high-sensitivity C-reactive protein. In addition, Paraprevotella, Succinatimonas, and Bacillus were also associated with greater plaque volume. Ten bacteria were associated with larger fibrous cap thickness. Some were associated with protective biomarker changes; Anaerostipes had negative correlations with trimethylamine N-oxide, tumor necrosis factor α, and interleukin-6, and Dielma had negative correlations with trimethylamine N-oxide, white blood cells, plasminogen activator inhibitor-1, and homocysteine, and a positive correlation with high-density lipoprotein cholesterol. Conclusions Bacteria that were associated with vulnerable coronary plaque phenotype and greater plaque burden were identified. These bacteria were also associated with elevated inflammatory or prothrombotic biomarkers. Registration URL: https://www.umin.ac.jp/ctr/; Unique identifier: UMIN000041692.

Abstract
Recently, monolayer SnS, a two-dimensional group IV monochalcogenide, was grown on a mica substrate at the micrometer-size scale by the simple physical vapor deposition (PVD), resulting in the successful demonstration of its in-plane room temperature ferroelectricity. However, the reason behind the monolayer growth remains unclear because it had been considered that the SnS growth inevitably results in a multilayer thickness due to the strong interlayer interaction arising from lone pair electrons. Here, we investigate the PVD growth of monolayer SnS from two different feed powders, highly purified SnS and commercial phase-impure SnS. Contrary to expectations, it is suggested that the mica substrate surface is modified by sulfur evaporated from the Sn2S3 contaminant in the as-purchased powder and the lateral growth of monolayer SnS is facilitated due to the enhanced surface diffusion of SnS precursor molecules, unlike the growth from the highly purified powder. This insight provides a guide to identify further controllable growth conditions.

Abstract
Abstract
Background
Recent Cochrane Systematic Review suggested that the participation in cardiac rehabilitation is associated with approximately 20% lower cardiovascular mortality and morbidity. Exercise therapy is the key component of cardiac rehabilitation programs. In recent years, innovative technologies have been introduced into the field of rehabilitation, and a typical example is the wearable cyborg Hybrid Assistive Limb (HAL). The wearable cyborg HAL provides motion assistance based on detection of bioelectrical signals on the skin surface when muscle forces are generated. The lumbar-type HAL is expected to expand the therapeutic options for severe cardiac patients who have difficulty in performing usual cardiac rehabilitation programs, such as bicycle pedaling or walking.
Purpose
We aim to compare the efficacy of exercise therapy performed with motion assistance from a lumbar-type HAL versus conventional training (sit-to-stand exercise without HAL) in patients with chronic heart failure.
Methods
This clinical trial is a randomized, non-blinded, and controlled study. Twenty-eight heart failure patients (73.1±13.8 years) who have difficulty in walking at the usual walking speed of healthy subjects were randomly assigned to 2 groups (HAL group or control group) with a 1:1 allocation ratio and performed sit-to stand exercise either with HAL or without HAL for 5 to 30 minutes once a day, and 6 to 10 days during the study period. The brain natriuretic peptide (BNP), isometric knee extensor strength, standing ability (30-seconds chair-stand test: CS-30), short physical performance battery (SPPB) and 6-minute walking distance (6MWD) were measured before and after the completion of cardiac rehabilitation. Cardiac events such as death, re-hospitalization, myocardial infarction and worsening of angina pectoris and heart failure during 1 year after discharge were evaluated.
Results
There was no significant difference in the number of days of exercise therapy between the two groups. BNP, SPPB and 6MWD were improved in both groups. In the HAL group, the isometric knee extensor strength (0.29±0.11 vs 0.35±0.11 kgf/kg, p=0.003) significantly improved and CS-30 (5.5±5.1 vs 8.2±5.3, p=0.054) tended to improve. However, in the control group, either the isometric knee extensor strength (0.35±0.11 vs 0.36±0.14 kgf/kg, p=0.424) or CS-30 (6.0±4.3 vs 9.2±6.2, p=0.075) did not significantly change. HAL group showed significantly more improvement in the isometric knee extensor strength than control group (p=0.045). Cardiac events occurred in 20% in the HAL group and 43% in the control group.
Conclusion
The improvement in isometric knee extensor strength with the assistance from lumbar-type HAL suggests that exercise therapy using this device may be useful in chronic heart failure patients with flail or sarcopenia, a strong poor prognostic factor in these patients.

Abstract
BACKGROUND The impact of diabetes mellitus (DM) on clinical outcomes after percutaneous coronary intervention (PCI) for unprotected left main (ULM) distal bifurcation lesions in patients with chronic kidney disease (CKD) is poorly understood in the era of drug-eluting stents (DESs). OBJECTIVE We assessed the impact of DM on clinical outcomes after PCI for ULM distal bifurcation lesions in CKD patients compared to patients without DM. METHODS We identified 1,832 consecutive patients who underwent PCI for ULM lesions at New Tokyo Hospital, Matsudo, Japan, San Raffaele Scientific Institute, Milan, Italy, and EMO-GVM, Centro Cuore Columbus, Milan, Italy between January 2005 and August 2015. Of the 1,832 patients, 1,391 were treated with DESs. We excluded 750 patients without CKD and 89 hemodialysis patients. Finally, 552 patients with CKD were included: 219 with DM (DM group) and 333 without DM (no DM group). The primary endpoint was target lesion failure (TLF) at 5 years. TLF was defined as a composite of cardiac death, target lesion revascularization (TLR), and myocardial infarction. RESULTS Patients in the DM group were more likely to have hypertension, dyslipidemia, peripheral artery disease, and lower ejection fraction and were more frequently using insulin for DM. The TLF rate during the follow-up period was significantly higher in the DM than in the no DM group (adjusted hazard ratio [HR] 1.50; 95% confidence interval [CI] 1.06-2.13; p = 0.023). Cardiac mortality was comparable between both groups (adjusted HR 1.11; 95% CI 0.63-1.95; p = 0.71). The TLR rate was significantly higher in the DM group than in the no DM group (adjusted HR 1.69; 95% CI 1.12-2.54; p = 0.012). CONCLUSION DM is strongly associated with adverse event after PCI for ULM distal bifurcation lesions in CKD patients compared to those without DM.

Abstract
Objectives
We assessed clinical outcomes after percutaneous coronary intervention (PCI) for unprotected left main (ULM) using current generation drug eluting stents (cDES) in hemodialysis (HD) patients compared to general populations.
Methods
We identified 1269 consecutive patients who underwent PCI for ULM distal bifurcation lesions. Of them, 563 patients were treated with cDES (512 non HD and 51 HD patients). The primary endpoint was target lesion failure (TLF) at 3 years, defined as a composite of cardiac death, target lesion revascularization (TLR) and myocardial infarction (MI).
Results
HD group was more likely to have diabetes mellitus (70.0% vs. 45.8%, p=0.002), peripheral artery disease (56.0% vs. 14.9%, p<0.001), and lower ejection fraction (52.6% vs. 56.3%, p=0.026). The rate of TLF at 3 years was significantly higher in the HD group (adjusted Hazard ratio [HR] 2.59; 95% confidence interval [CI], 1.54–4.37; p<0.001). Cardiac mortality was significantly higher in the HD group (adjusted HR 4.49; 95% CI, 2.07–9.74; p<0.001). The rates of TLR for LM-left anterior descending artery (LAD) and left circumflex ostium (LCXos) were significantly higher in the HD group (LMT-LAD: adjusted HR 3.10; 95% CI, 1.31–7.33; p=0.01, LCXos: adjusted HR 2.56; 95% CI, 1.32–4.94; p=0.005). The rate of MI was similar between the 2 groups.
Conclusions
Hemodialysis was strongly associated with adverse events after PCI for ULM distal bifurcation lesions even with cDES.

Abstract
AIMS To establish the value of the SYNTAX Score-II (SS-II) in predicting long-term mortality of patients treated with left main PCI (LM-PCI) using second-generation drug-eluting stents (DES). METHODS AND RESULTS The SYNTAX score (SS) and the SS-II were calculated in 804 patients included in the FAILS-2 registry (failure in left main study with 2nd generation stents). Patients were classified in low (SS-II ≤33; n = 278, 34.6%), intermediate (SS-II 34-43; n = 260, 32.3%) and high (SS-II ≥44; n = 266, 33.1%) SS-II tertiles. Primary endpoint was all-cause mortality. A significant difference in long-term mortality was noted (5.2 ± 3.6 years): 4.1, 7.5, and 16.7% in low, mid and high SS-II tertiles respectively (p < .001). SS-II score was more accurate in predicting mortality than SS (AUC = 0.73; 95%CI: 0.67-0.79 vs. AUC = 0.55; 95%CI: 0.48-0.63, respectively; p < .001). SS-II led to a reclassification in the risk of all-cause mortality re-allocating 73% of patients from the CABG-only indication to PCI or equipoise PCI-or-CABG indication. Using multiple Cox regression analysis, SS-II (HR: 1.07; 95%CI: 1.05-1.09; p < .001), along with Acute coronary syndrome (ACS) (HR: 1.66; 95%CI: 1.03-2.66; p = .07) and Cardiogenic shock (CS) (HR: 2.82 (95%CI: 1.41-5.64; p = .003) were independent predictors of long-term mortality. SS-II (HR: 1.05; 95%CI: 1.04-1.06; p < .001) along with Insulin dependent Type 2 DM (HR: 1.58, 95%CI: 1.09-2.30.; p < .05), ACS (HR: 1.58, 95%CI: 1.16-2.14; p < .001) and CS (HR: 2.02 95%CI 1.16-3.53; p < .05), were independent predictors of long-term MACE. CONCLUSION The SS-II was superior to the SS in predicting outcomes associated with contemporary LM-PCI. In this real-world population, two clinical variables not included in the SS-II, ACS and T2DM, were identified as additional markers of poor outcome.

Abstract
Background:
The risk factors and long-term clinical outcomes of patients with definite stent thrombosis (ST) after second-generation drug-eluting stent (DES) implantation have not yet been adequately assessed.
Methods and Results:
The REAL-ST (Retrospective Multicenter Registry of ST After First- and Second-Generation DES Implantation) included 313 definite ST of second-generation DES (early ST, n=179; late ST, n=66; very late ST, n=68). Four patients without definite ST of second-generation DES were identified as control patients for each ST case. Risk factors of definite ST were mostly different according to the timing of ST: ST-segment–elevation myocardial infarction, non–ST-segment–elevation myocardial infarction, and unstable angina at presentation, current smoking, left ventricular ejection fraction <40%, prior percutaneous coronary intervention, stent overlap, severely calcified lesion, left main coronary artery lesion, proximal left anterior descending lesion, postdiameter stenosis ≥20%, for early ST; age <70 years, ST-segment–elevation myocardial infarction at presentation, hemodialysis, left ventricular ejection fraction <40%, in-stent restenosis, and severely calcified lesion for late ST; and proximal left anterior descending lesion and in-stent restenosis for very late ST. Cumulative 4-year incidence of death after the index ST events was significantly higher in the ST patients than control patients (33.0% versus 12.3%,
P
<0.001 for early ST versus control; 30.6% versus 14.2%,
P
<0.001 for late ST versus control; and 28.0% versus 13.0%,
P
<0.001 for very late ST versus control, respectively).
Conclusions:
Risk factors of definite ST after second-generation DES implantation were mostly different according to the timing of ST. Definite ST patients showed unfavorable long-term clinical outcomes compared with those without definite ST.

New-generation drug-eluting stents for left main coronary artery disease according to the EXCEL trial enrollment criteria: Insights from the all-comers, international, multicenter DELTA-2 registry. Int J Cardiol 2019; 280:30-37. [PMID: 30595357 DOI: 10.1016/j.ijcard.2018.12.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2018] [Revised: 11/28/2018] [Accepted: 12/03/2018] [Indexed: 11/18/2022]
Abstract
BACKGROUND Percutaneous coronary intervention (PCI) has been established as an alternative treatment option to coronary artery by-pass graft (CABG) surgery in patients with left main coronary artery disease (LMCAD). Whether the findings of randomized controlled trials are applicable to a real-world patient population is unclear. METHODS We compared the outcomes of PCI with new-generation DES in the all-comer, international, multicenter DELTA-2 registry retrospectively evaluating mid-term clinical outcomes with the historical CABG cohort enrolled in the DELTA-1 registry according to the EXCEL key inclusion or exclusion criteria. The primary endpoint was the composite of death, myocardial infarction, or stroke at the median time of follow-up time of 501 days. The consistency of the effect of DELTA-2 PCI versus DELTA-1 CABG according to the EXCEL enrollment criteria was tested using propensity score-adjusted Cox regression models. RESULTS Out of 3986 patients enrolled in the DELTA-2 PCI registry, 2418 were EXCEL candidates and 1568 were not EXCEL candidates. The occurrence of the primary endpoint was higher among non-EXCEL candidates compared with EXCEL candidates (15.4% vs. 6.9%; hazard ratio 2.52; 95% confidence interval 2.00-3.16; p < 0.001). Among 901 patients enrolled in the historical DELTA-1 CABG cohort, 471 were EXCEL candidates and 430 were not EXCEL candidates. When comparing the DELTA-2 PCI with the DELTA-1 CABG cohort, the occurrence of the primary endpoint was lower in the PCI group compared with the historical CABG cohort among EXCEL candidates (6.9% vs. 10.7%; adjusted hazard ratio: 0.65; 95% confidence interval: 0.45-0.92), while no significant difference was observed among non-EXCEL candidates (15.4% vs. 12.5%; adjusted hazard ratio: 0.94; 95% confidence interval: 0.67-1.33) with evidence of statistical interaction (adjusted interaction p-value = 0.002). CONCLUSIONS In a real-world population, PCI can be selected more favorably as an alternative to CABG in patients fulfilling the enrollment criteria of the EXCEL trial.

Abstract
OBJECTIVES To investigate the long-term clinical outcomes of second-generation drug-eluting stent (2G-DES) implantation for the treatment of complex unprotected left main coronary artery (ULMCA) bifurcation lesions with different two-stent techniques. BACKGROUND Several two-stent techniques for ULMCA bifurcation lesions have been described. However, a paucity of data exists regarding the optimal strategy, especially in the 2G-DES era. METHODS The FAILS-2 registry enrolled 1270 consecutive patients treated for ULMCA stenosis with 2G-DES. We compared long-term outcomes of different two-stent strategies in patients who underwent PCI for complex ULMCA bifurcation disease. The primary endpoints were the incidence of death and major adverse cardiac events (MACE, defined as a composite of all-cause death, myocardial infarction [MI], target-lesion revascularization [TLR], and stent thrombosis [ST]) at long-term follow-up. RESULTS A total of 238 patients were included in the present analysis. T-stenting strategy was used in 66 patients, mini-crush in 104 patients, and culotte in 68 patients. After a median follow-up of 2.27 years, death rates were comparable for the three techniques (9.3% T-stenting vs 9.0% mini-crush vs 4.5% culotte [P=.48]). MACE rates were also similar between the three groups (22% T-stenting vs 26% mini-crush vs 31% culotte [P=.50]). Finally, we showed no differences in MI, ST, and TLR rates between groups. At multivariate analysis, no significant advantage of one technique over the others was observed. CONCLUSION T-stenting, mini-crush, and culotte techniques using 2G-DES for ULMCA bifurcation disease showed similar clinical outcomes at long-term follow-up. MACE rates were mainly driven by in-stent restenosis at the circumflex ostium.

Abstract
OBJECTIVES The aim of this study was to evaluate clinical outcomes of unprotected left main coronary artery percutaneous coronary intervention (PCI) with new-generation drug-eluting stents in a "real world" population. BACKGROUND PCI of the unprotected left main coronary artery is currently recommended as an alternative to coronary artery bypass grafting (CABG) in selected patients. METHODS All consecutive patients with unprotected left main coronary artery stenosis treated by PCI with second-generation drug-eluting stents were analyzed in this international, all-comers, multicenter registry. The results were compared with those from the historical DELTA 1 (Drug Eluting Stent for Left Main Coronary Artery) CABG cohort using propensity score stratification. The primary endpoint was the composite of death, myocardial infarction (MI), or stroke at the median time of follow-up. RESULTS A total of 3,986 patients were included. The mean age was 69.6 ± 10.9 years, diabetes was present in 30.8%, and 21% of the patients presented with acute MI. The distal left main coronary artery was involved in 84.6% of the lesions. At a median of 501 days (≈17 months) of follow-up, the occurrence of the primary endpoint of death, MI, or cerebrovascular accident was lower in the PCI DELTA 2 group compared with the historical DELTA 1 CABG cohort (10.3% vs. 11.6%; adjusted hazard ratio: 0.73; 95% confidence interval: 0.55 to 0.98; p = 0.03). Of note, an advantage of PCI was observed with respect to cerebrovascular accident (0.8% vs. 2.0%; adjusted hazard ratio: 0.37; 95% confidence interval: 0.16 to 0.86; p = 0.02), while an advantage of CABG was observed with respect to target vessel revascularization (14.2% vs. 2.9%; adjusted hazard ratio: 3.32; 95% confidence interval: 2.12 to 5.18; p < 0.0001). CONCLUSIONS After a median follow-up period of 17 months, PCI with new-generation drug-eluting stents was associated with an overall low rate of the composite endpoint of death, MI, or cerebrovascular accident.

Abstract
OBJECTIVE To evaluate the outcome of patients undergoing PCI for unprotected left main coronary artery (ULMCA) disease with different drug-eluting stent (DES) types. BACKGROUND Published literature suggests that second-generation DES options have differing vascular responses and outcomes, but there is a paucity of data in real-life patients in the LM setting. METHODS This is a retrospective, multicenter study, including patients treated with a second-generation DES for ULMCA disease between 2007 and 2015. The primary endpoint was target-lesion revascularization (TLR). Secondary endpoints were major adverse cardiac events, myocardial infarction (MI), and stent thrombosis (ST). RESULTS A total of 1209 patients were enrolled; 840 patients (69.5%) received an everolimus-eluting stent (EES), 133 patients (11.0%) received a zotarolimus-eluting stent (ZES), and 236 patients (19.5%) received a biodegradable polymer, biolimus-eluting stent (BP-BES). During a mean follow-up of 722 ± 640 days, TLR occurred in 47 patients (3.8%). At univariate analysis, EES patients had a lower TLR rate (3.6% vs 4.5% in ZES vs 4.2% in BP-BES), which was statistically significant at multivariate analysis (hazard ratio, 0.50; 95% confidence interval, 0.27-0.93; P=.03). No differences in major adverse cardiac events, death, MI, or ST were observed between groups. CONCLUSION The safety profile of the stents used was comparable over the follow-up period. However, EES patients had lower restenosis rates, with a reduced need for repeat PCI.

Abstract
OBJECTIVES This study evaluated angiographic success and in-hospital outcomes of percutaneous coronary intervention (PCI) with rotational atherectomy (RA) in patients with low left ventricular ejection fraction (LVEF). DESIGN Between January 2010 and March 2014, 272 consecutive patients with heavily calcified lesions underwent elective PCI with RA. Of these, 33 patients had LVEF ≤35% (low LVEF group), whereas 237 patients had LVEF >35% (preserved LVEF group). The primary endpoint was angiographic success and in-hospital major adverse cardiac events (MACE). MACE included death from any cause, postprocedure onset MI, emergency coronary artery bypass grafting, and target vessel revascularization. The secondary endpoints were MACE and the components within 30days after PCI. The components of MACE were evaluated. RESULTS Angiographic success, defined as <30% residual stenosis with thrombolysis in myocardial infarction flow 3 at final angiography, was achieved in all patients without fatal complications. Intra-aortic ballon pumping (IABP) was used significantly more frequently in the low LVEF group compared with the preserved LVEF group (15.2% vs. 2.1%, p = .003). There were no significant differences between groups regarding in-hospital and clinical outcomes within 30 days following PCI. CONCLUSION If medications and mechanical support were appropriately performed, the angiographic success rate and in-hospital MACE rate of PCI with RA in patients with low LVEF could be expected to have good outcomes similar to those for patients with preserved LVEF.

Abstract
Transradial access (TRA) is often avoided in favor of the transfemoral access (TFA) during percutaneous coronary interventions of the unprotected left main coronary artery (ULM), due to technical and safety concerns. The aim of this study was to compare the performance of TRA and TFA in the treatment of ULM with second-generation drug-eluting stents. Consecutive patients who underwent percutaneous coronary intervention on ULM with second-generation drug-eluting stents were retrospectively enrolled in the multicenter Failure in Left Main Study With 2nd Generation Stents (FAILS 2) registry. Patients were stratified according to the arterial access. The choice between TRA and TFA was left to each operator's preferences. Bleedings during index hospitalization were the primary end point. Secondary end points were major adverse cardiovascular events (a composite of death, reinfarction, and target lesion revascularization), the single components of major adverse cardiovascular events at follow-up and stent thrombosis. Propensity score matching was executed to account for possible confounding. Overall, 1,247 patients were enrolled (23.2% [289] of female gender, mean age 70.2 ± 10.2 years). Diagnosis at presentation was stable angina in 603 (48.7%) cases, non-ST-segment elevation acute coronary syndrome in 465 (37.3%), ST-segment elevation myocardial infarction in 117 (9.5%). Mean follow-up was 726 ± 654 days. After propensity score with matching, 354 patients were included. The primary end point was significantly reduced in patients treated with TRA (2.0% vs 4.0%, p = 0.042), whereas no differences emerged pertaining the secondary end points, including target lesion revascularization and reinfarction. In conclusion, TRA may reduce in-hospital bleedings in patients undergoing percutaneous treatment of the ULM, without increasing the rate of adverse cardiovascular events at follow-up, and may therefore be safely used in the treatment of the ULM.

Abstract
AIMS Bioresorbable vascular scaffolds (BVS) represent a novel therapeutic option for the treatment of coronary artery diseases. The objective of this study was to evaluate the feasibility of BVS implantation in complex chronic total occlusions (CTO). METHODS AND RESULTS The present report is a multicentre registry evaluating results after BVS deployment in challenging CTO lesions, defined as J-CTO score ≥2 (difficult or very difficult). A total of 105 patients were included in the present analysis. The mean J-CTO score was 2.61 (difficult 52.4%, very difficult 47.6%). Device success and procedural success rates were 98.1% and 97.1%, respectively. The retrograde approach was used in 25.7% of cases. After wire crossing, predilatation was performed in all cases with a mean predilatation balloon diameter of 2.73±0.43 mm. The mean scaffold length was 59.75±25.85 mm, with post-dilatation performed in 89.5% of the cases and a mean post-dilatation balloon diameter of 3.35±0.44 mm. Post-PCI minimal lumen diameter was 2.50±0.51 mm and percentage diameter stenosis 14.53±10.31%. At six-month follow-up, a total of three events were reported: one periprocedural myocardial infarction, one late scaffold thrombosis and one additional target lesion revascularisation. CONCLUSIONS The present report suggests the feasibility of BVS implantation in complex CTO lesions, given adequate lesion preparation and post-dilatation, with good acute angiographic results and midterm clinical outcomes.

Impact of the Clinical Frailty Scale on Outcomes After Transcatheter Aortic Valve Replacement. Circulation 2017; 135:2013-2024. [DOI: 10.1161/circulationaha.116.025630] [Citation(s) in RCA: 165] [Impact Index Per Article: 23.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2016] [Accepted: 03/01/2017] [Indexed: 12/14/2022]
Abstract
Background:
The semiquantitative Clinical Frailty Scale (CFS) is a simple tool to assess patients’ frailty and has been shown to correlate with mortality in elderly patients even when evaluated by nongeriatricians. The aim of the current study was to determine the prognostic value of CFS in patients who underwent transcatheter aortic valve replacement.
Methods:
We utilized the OCEAN (Optimized Catheter Valvular Intervention) Japanese multicenter registry to review data of 1215 patients who underwent transcatheter aortic valve replacement. Patients were categorized into 5 groups based on the CFS stages: CFS 1-3, CFS 4, CFS 5, CFS 6, and CFS ≥7. We subsequently evaluated the relationship between CFS grading and other indicators of frailty, including body mass index, serum albumin, gait speed, and mean hand grip. We also assessed differences in baseline characteristics, procedural outcomes, and early and midterm mortality among the 5 groups.
Results:
Patient distribution into the 5 CFS groups was as follows: 38.0% (CFS 1-3), 32.9% (CFS4), 15.1% (CFS 5), 10.0% (CFS 6), and 4.0% (CFS ≥7). The CFS grade showed significant correlation with body mass index (Spearman’s ρ=−0.077,
P
=0.007), albumin (ρ=−0.22,
P
<0.001), gait speed (ρ=−0.28,
P
<0.001), and grip strength (ρ=−0.26,
P
<0.001). Cumulative 1-year mortality increased with increasing CFS stage (7.2%, 8.6%. 15.7%, 16.9%, 44.1%,
P
<0.001). In a Cox regression multivariate analysis, the CFS (per 1 category increase) was an independent predictive factor of increased late cumulative mortality risk (hazard ratio, 1.28; 95% confidence interval, 1.10–1.49;
P
<0.001).
Conclusions:
In addition to reflecting the degree of frailty, the CFS was a useful marker for predicting late mortality in an elderly transcatheter aortic valve replacement cohort.

In-Hospital and 1-Year Outcomes of Rotational Atherectomy and Stent Implantation in Patients With Severely Calcified Unprotected Left Main Narrowings (from the Multicenter ROTATE Registry). Am J Cardiol 2017; 119:1331-1337. [PMID: 28274573 DOI: 10.1016/j.amjcard.2017.01.014] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2016] [Revised: 01/09/2017] [Accepted: 01/09/2017] [Indexed: 11/26/2022]
Abstract
Heavily calcified unprotected left main (ULM) disease continues to be a challenging situation and represent a high-risk subset for interventional cardiologist. To date, there are limited data investigating the results after rotational atherectomy (RA) in this setting. The aim of this study was to investigate the in-hospital and 1-year outcomes after RA of heavily calcified ULM lesions. A retrospective cohort analysis was performed on all calcified patients with ULM (n = 86) enrolled in the multicenter international ROTATE registry (overall patients, n = 962). End points of the study were the in-hospital and 1-year incidence of major adverse cardiovascular events (MACE): a composite of death, myocardial infarction, and target-vessel revascularization in the ULM versus non-ULM group. Patients in the ULM group were older (p = 0.01) and more frequently with diabetes (p = 0.001) compared with the non-ULM group, whereas intravascular ultrasound guidance was higher, even if not systematic, in the ULM group (p <0.001). No difference was reported between ULM versus non-ULM groups in terms of in-hospital MACE (5.8% vs 8%). At 1 year, MACE rate was higher in ULM versus non-ULM (26.4% vs 14.9%, p = 0.002) mostly driven by target-vessel revascularization (20.3% vs 12.7%, p = 0.05). Even definite/probable stent thrombosis rate was higher in the ULM group (3.9% vs 0.8%). All these events were subacute and 2/3 (75%) were fatal. In conclusion, our multicenter experience shows that RA followed by stent implantation in patients with heavily calcified ULM narrowing is feasible and associated with good in-hospital results. Patient (age and diabetes) and procedural aspects (relatively low intravascular ultrasound guidance) may affect the worse subacute mid-term prognosis in the more complex ULM group.

Abstract
BACKGROUND There are only limited studies reporting clinical outcomes after bioresorbable vascular scaffold (BVS; Absorb; Abbott Vascular, Santa Clara, CA) implantation for coronary chronic total occlusions (CTO). The aim of this study was to evaluate the real-world feasibility and safety of BVS implantation for the treatment of CTO. METHODS AND RESULTS We retrospectively evaluated CTO cases treated with BVS from a multicenter registry. The primary end point was target lesion failure defined as a composite of cardiac death, target vessel myocardial infarction, and clinically driven target lesion revascularization. From September 2012 to November 2015, 65 patients with CTO were successfully treated with BVS. The mean age of patients was 60.8±11.0 years; 89.2% were male and 40.0% diabetic. The mean ejection fraction was 57.7±10.8%. The mean reference vessel diameter and CTO lesion length were 3.0±0.4 and 20.2±3.0 mm, respectively. The mean number of BVS deployed per patient was 1.8±0.7, of which mean diameter and total length were 3.0±0.4 and 47.6±19.9 mm, respectively. Postdilatation with noncompliant balloons (mean diameter 3.3±0.3 mm) was performed at high pressures (18.6±5.3 atm) in all cases. Intravascular ultrasound (n=34) or optical coherence tomography (n=31) was performed in all cases. During the follow-up period (median: 453 days, 25th and 75th percentiles: 230 and 703), there were no occurrences of target lesion failure or scaffold thrombosis. CONCLUSIONS BVS implantation for the treatment of CTO seems feasible and safe. Appropriate lesion preparation, high-pressure postdilatation, and the use of intravascular imaging are recommended to obtain the best possible final result.

Difference in vascular response between sirolimus-eluting- and everolimus-eluting stents in ostial left circumflex artery after unprotected left main as observed by optical coherence tomography. Int J Cardiol 2016; 230:284-292. [PMID: 28065691 DOI: 10.1016/j.ijcard.2016.12.122] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2016] [Revised: 12/01/2016] [Accepted: 12/17/2016] [Indexed: 10/20/2022]
Abstract
BACKGROUND Kissing-balloon technique (KBT) is commonly performed during percutaneous coronary intervention of distal unprotected left main coronary artery (ULM) aiming at obtaining optimal opening of the side branch (left circumflex artery; LCX) ostium. Nonetheless, detailed evaluation of vascular response to stents in LCX ostium is lacking. We therefore evaluated the vascular response to different drug-eluting stents (DES) in ostial LCX after ULM by means of optical coherence tomography (OCT). METHODS We prospectively enrolled 38 consecutive patients with ULM disease, who were treated with single-stent procedure using DES, crossover the ULM-left anterior descending artery (LAD) followed by KBT. Twelve patients were treated with sirolimus-eluting stents (SES) and 26 patients were treated with everolimus-eluting stents (EES). OCT was conducted at post-PCI and 9-month follow-up. We evaluated the DES-vessel interactions and number of stent struts at the side branch (LCX) ostium (SO) at post-PCI, and compared the narrowing of ostial area at LCX between SES and EES. RESULTS Post-procedure, the number of stent struts at SO was significantly higher in SES compared to EES (median 14.47% vs 0.19%, p<0.001). The narrowing of LCX ostial area at follow-up was more pronounced in SES compared with EES (29.16% vs 2.46%, respectively, p<0.001). Linear regression analysis showed a high correlation between the number of stent struts in LCX ostium and ostial area narrowing (r=0.771, p<0.001). CONCLUSIONS OCT showed differences between EES- and SES-vessel interactions at ULM bifurcation PCI. Number of LCX ostium struts at post-PCI impacted the narrowing of ostial area at 9-month follow-up.

Abstract
We report a rare case of an incarcerated retroperitoneal hernia with or involving the small bowel through the orifice between the right external and internal iliac vessels. A 39-year-old woman was admitted to our hospital because of vomiting and abdominal pain. She had a history of right oophorocystectomy and appendectomy. Abdominal computed tomography revealed small bowel obstruction resulting from an incarcerated retroperitoneal hernia. The small bowel herniated into the retroperitoneal fossa through the orifice between the right external and internal iliac vessels. Laparoscopic reduction of the small bowel was performed, followed by ligation of the sac and placement of a mesh prosthesis through the preperitoneal approach, using a lower midline incision along the previous laparotomy scar. Her postoperative course was uneventful and no recurrence has been observed after surgery.
