Abstract

Aims: The aim of this IVUS substudy was to assess the efficacy of the Y-shaped Medtronic bifurcation-dedicated stent (BDS) for the treatment of de novo coronary bifurcated lesions. Methods and Results: In the BRANCH trial, post-procedure IVUS was performed in 45 patients. IVUS was available in both branches in 19 lesions and only the main branch (MB) in 26 lesions. IVUS analysis included four distinct locations: proximal MB, bifurcation site, distal MB, and side branch (SB). Lumen symmetry was calculated as minimum/maximum lumen diameters. The quantity of isolated stent struts across the SB ostium was used to assess inadequate strut apposition to the carina resulting in partial jailing of the SB orifice. A minimum stent area (MSA) <4 mm2 was found in 0% of proximal and distal MB, and in 15.4% of SB. In SB, MSA was located mainly at mid or distal segments (84.6%), rather than at the SB ostium. Eccentric stent expansion and edge dissection were seen primarily at proximal MB. Isolated struts were seen in only 20.9% of SB ostia with a minimum length of 0.7+/-0.4 mm. Conclusion(s): Implantation of BDS resulted in adequate stent dimensions and strut apposition at the carina and SB ostium.

Abstract

We analyze the data of the TAMA300 detector to search for gravitational waves from inspiraling compact star binaries with masses of the component stars in the range 1M[sun]–3M[sun]. In this analysis, 2705 hours of data, taken during the years 2000–2004, are used for the event search. We combine the results of different observation runs, and obtain a single upper limit on the rate of the coalescence of compact binaries in our Galaxy of 20 per year at a 90% confidence level. In this upper limit, the effects of various systematic errors such as the uncertainty of the background estimation and the calibration of the detector's sensitivity are included.

Abstract

Background: The Resolute stent is a newly developed system with a bio-histocompatible polymer that allows programmed drug delivery up to 180 days. The aim of this intravascular ultrasound (IVUS) analysis was to evaluate the short- (4 months) and mid-term (9 months) efficacy using the Resolute stent. Methods and Results: Data were derived from the RESOLUTE trial, a prospective, multicenter, non-randomized, single-arm study to treat de novo native coronary artery lesions. This trial included 2 cohorts with different follow-up periods, and all enrollment patients in this trial received IVUS study. Follow-up IVUS was available in 24 patients (4-month group) and 88 patients (9-month group). Neointimal obstruction (%) was defined as neointimal volume divided by stent volume. Cross-sectional narrowing (CSN, %) was defined as neointimal area divided by stent area. No significant differences in vessel, lumen and stent volume at post-procedure were observed within stented segments between the 4- and 9-month follow-up groups. Although neointimal volume and % neointimal obstruction showed no significant difference between the 2 groups (% neointimal obstruction: 2.2+/-2.5 vs 3.7+/-4.0%, P=0.09), maximum CSN was significantly larger in the 9-month group. There were 7 cases of late incomplete stent apposition. Conclusion(s): These IVUS results showed minimum growth of neointimal proliferation by the Resolute stent throughout the stented segment up to 9 months follow up.

Abstract

Background: Restenosis of bifurcation lesions remains high even in the DES era due to postprocedural stent under-expansion inadequate coverage, and/or multiple layers of overlapping stents at the side branch (SB) ostium and carina. The aim of this IVUS study was to investigate stent expansion and coverage at the SB ostium and carina in bifurcation lesions treated with the Medtronic Y-shaped bifurcation-dedicated stent (BDS; Medtronic Cardiovascular, SantaRosa, CA) and with the conventional side branch angioplasty (SBA). Method(s): Post procedure IVUS data of BDS (n=45) from the first-m-man, prospective, multicenter. non-randomized single-arm BRANCH trial was compared with data of SBA (n=19) without provisional stent placement in the SB. IVUS analysis included 4 distinct locations: proximal mam branch, bifurcation site, distal mam branch, and SB. In addition to the standard 3D IVUS parameters, lumen symmetry at the border between the bifurcation site and each branch was calculated as minimum/maximum lumen diameters. Floating struts were defined as stent struts across the SB ostium. Result(s): Lumen volume in SB was larger and a minimum lumen area <4 mm2 in SB was less frequent in BDS compared with SBA. The SB ostium was larger and more symmetric in BDS than in SBA. Floating struts at the SB ostium were detectedless frequently in BDS (20.9 vs. 78.9%, p<0.0001), and the axial segment length with floating struts was significantly shorter in BDS compared with SBA (0.7 +/- 0.4 vs. 1.5 +/- 0.8 mm, p=0.019), suggesting better struts coverage at the carina in BDS than in SBA. (Table Presented) Conclusion(s): Implantation of the bifurcation-dedicated stent appears to achieve better immediate results yielding adequate stent expansion and coverage at the side branch ostium and carina in comparison to conventional side branch angioplasty.

Abstract

We search for coincident gravitational wave signals from inspiralling neutron star binaries using LIGO and TAMA300 data taken during early 2003. Using a simple trigger exchange method, we perform an intercollaboration coincidence search during times when TAMA300 and only one of the LIGO sites were operational. We find no evidence of any gravitational wave signals. We place an observational upper limit on the rate of binary neutron star coalescence with component masses between 1 and 3M of 49 per year per Milky Way equivalent galaxy at a 90% confidence level. The methods developed during this search will find application in future network inspiral analyses. © 2006 The American Physical Society.

Abstract

We report on the first joint search for gravitational waves by the TAMA and LIGO collaborations. We looked for millisecond-duration unmodeled gravitational-wave bursts in 473 hr of coincident data collected during early 2003. No candidate signals were found. We set an upper limit of 0.12 events per day on the rate of detectable gravitational-wave bursts, at 90% confidence level. From software simulations, we estimate that our detector network was sensitive to bursts with root-sum-square strain amplitude above approximately 1-3×10-19Hz-1/2 in the frequency band 700-2000 Hz. We describe the details of this collaborative search, with particular emphasis on its advantages and disadvantages compared to searches by LIGO and TAMA separately using the same data. Benefits include a lower background and longer observation time, at some cost in sensitivity and bandwidth. We also demonstrate techniques for performing coincidence searches with a heterogeneous network of detectors with different noise spectra and orientations. These techniques include using coordinated software signal injections to estimate the network sensitivity, and tuning the analysis to maximize the sensitivity and the livetime, subject to constraints on the background. © 2005 The American Physical Society.

Abstract

Background: The prognostic impact of coronary microvascular dysfunction after percutaneous coronary intervention (PCI) remains unclear in patients with stable coronary artery disease. This study sought to investigate the prognostic value of microvascular function measured immediately after PCI in patients with stable coronary artery disease. Methods: We enrolled 572 patients with stable coronary artery disease who underwent PCI and elective measurement of the index of microcirculatory resistance (IMR) immediately after PCI from 8 centers in 4 countries. Impaired microvascular function was defined as IMR≥25 (high IMR). Major adverse cardiac events, including death, myocardial infarction (MI) and target vessel revascularization, were evaluated. Results: During a median follow-up duration of 4.0 years, the cumulative major adverse cardiac events rate was significantly higher in the high IMR group (n=66/148) compared with the low IMR group (n=128/424; hazard ratio [HR], 1.56; 95% CI, 1.16−2.105; P =0.001), primarily due to a higher rate of periprocedural MI (HR, 1.59; 95% CI, 1.11−2.28; P =0.004) but also due to higher rates of mortality (HR, 1.59; 95% CI, 0.76−3.35; P =0.22), spontaneous MI (HR, 2.10; 95% CI, 0.67−6.63; P =0.20) and target vessel revascularization (HR, 1.40; 95% CI, 0.77−2.54; P =0.27). Cumulative risk for death, spontaneous MI, and target vessel revascularization was higher in the high IMR group (HR, 1.55; 95% CI, 0.99−2.43; P =0.056), as was death and spontaneous MI alone (HR, 1.79; 95% CI, 0.96−3.36; P =0.065). On multivariable analysis, high IMR post-PCI was an independent predictor of major adverse cardiac events. Conclusions: IMR measured immediately after PCI predicts adverse events in patients with stable coronary artery disease.

Abstract

Purpose: The underlying difference between intermittent claudication (IC) and critical limb-threatening ischemia (CLTI) still remains unclear. This prospective multicenter observational study aimed to clarify differences in clinical features and prognostic outcomes between IC and CLTI, and prognostic factors in patients undergoing endovascular therapy (EVT)., Materials and Methods: A total of 692 patients with 808 limbs were enrolled from 20 institutions in Japan. The primary measurements were the 3-year rates of major adverse cardiovascular event (MACE) and reintervention., Results: Among patients, 79.0% had IC and 21.0% had CLTI. Patients with CLTI were more frequently women and more likely to have impaired functional status, undernutrition, comorbidities, hypercoagulation, hyperinflammation, distal artery disease, short single antiplatelet and long anticoagulation therapies, and late cilostazol than patients with IC. Aortoiliac and femoropopliteal diseases were dominant in patients with IC and infrapopliteal disease was dominant in patients with CLTI. Patients with CLTI underwent less frequently aortoiliac intervention and more frequently infrapopliteal intervention than patients with IC. Longitudinal change of ankle-brachial index (ABI) exhibited different patterns between IC and CLTI (pinteraction=0.002), but ABI improved after EVT both in IC and in CLTI (p<0.001), which was sustained over time. Dorsal and plantar skin perfusion pressure in CLTI showed a similar improvement pattern (pinteraction=0.181). Distribution of Rutherford category improved both in IC and in CLTI (each p<0.001). Three-year MACE rates were 20.4% and 42.3% and 3-year reintervention rates were 22.1% and 46.8% for patients with IC and CLTI, respectively (log-rank p<0.001). Elevated D-dimer (p=0.001), age (p=0.043), impaired functional status (p=0.018), and end-stage renal disease (p=0.019) were independently associated with MACE. After considering competing risks of death and major amputation for reintervention, elevated erythrocyte sedimentation rate (p=0.003) and infrainguinal intervention (p=0.002) were independently associated with reintervention. Patients with CLTI merely showed borderline significance for MACE (adjusted hazard ratio 1.700, 95% confidence interval 0.950-3.042, p=0.074) and reintervention (adjusted hazard ratio 1.976, 95% confidence interval 0.999-3.909, p=0.05)., Conclusions: The CLTI is characterized not only by more systemic comorbidities and distal disease but also by more inflammatory coagulation disorder compared with IC. Also, CLTI has approximately twice MACE and reintervention rates than IC, and the underlying inflammatory coagulation disorder per se is associated with these outcomes., Clinical Impact: The underlying difference between intermittent claudication (IC) and critical limb-threatening ischemia (CLTI) still remains unclear. This prospective multicenter observational study, JPASSION study found that CLTI was characterized not only by more systemic comorbidities and distal disease but also by more inflammatory coagulation disorder compared to IC. Also, CLTI had approximately twice major adverse cardiovascular event (MACE) and reintervention rates than IC. Intriguingly, the underlying inflammatory coagulation disorder per se was independently associated with MACE and reintervention. Further studies to clarify the role of anticoagulation and anti-inflammatory therapies will contribute to the development of post-interventional therapeutics in the context of peripheral artery disease., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: O.K. has received a research grant and consulting fees from Terumo and has received lecture fees from Medicon, Otsuka Pharmaceutical, and Kowa Pharmaceutical.

Abstract

Background: Microvascular resistance reserve (MRR) has been proposed as a specific metric to quantify coronary microvascular function. The long-term prognostic value of MRR measured in stable patients immediately after percutaneous coronary intervention (PCI) is unknown. This study sought to determine the prognostic value of MRR measured immediately after PCI in patients with stable coronary artery disease., Methods: This study included 502 patients with stable coronary artery disease who underwent elective PCI and coronary physiological measurements, including pressure and flow estimation using a bolus thermodilution method after PCI. MRR was calculated as coronary flow reserve divided by fractional flow reserve times the ratio of mean aortic pressure at rest to that at maximal hyperemia induced by hyperemic agents. An abnormal MRR was defined as ≤2.5. Major adverse cardiac events (MACEs) were defined as a composite of all-cause mortality, any myocardial infarction, and target-vessel revascularization., Results: During a median follow-up of 3.4 years, the cumulative MACE rate was significantly higher in the abnormal MRR group (12.5 versus 8.3 per 100 patient-years; hazard ratio 1.53 [95% CI, 1.10-2.11]; P <0.001). A higher all-cause mortality rate primarily drove this difference. On multivariable analysis, a higher MRR value was independently associated with lower MACE and lower mortality. When comparing 4 subgroups according to MRR and the index of microcirculatory resistance, patients with both abnormal MRR and index of microcirculatory resistance (≥25) had the highest MACE rate., Conclusions: An abnormal MRR measured immediately after PCI in patients with stable coronary artery disease is an independent predictor of MACE, particularly all-cause mortality., Competing Interests: Disclosures Dr Fearon receives research support from Abbott and Medtronic. He had a consulting relationship with CathWorks and has stock options in HeartFlow. The other authors report no conflicts.

Abstract

Diagnosing cardiac sarcoidosis (CS), especially in isolated cases, is challenging, particularly due to the limitations of endomyocardial biopsy, leading to potential undiagnosed cases in pacemaker-implanted patients. This study aims to provide real world findings to support new guideline for CS using 18F-fluoro-deoxyglucose positron-emission tomography computed tomography (FDG-PET/CT) which give a definite diagnosis of isolated CS (iCS) without histological findings. We examined consecutive patients with cardiac pacemakers for atrioventricular block (AV-b) attending our outpatient pacemaker clinic. The patients underwent periodical follow-up echocardiography and were divided into two groups according to echocardiographic findings: those with suspected CS and those without suspected CS. Patients suspected of having nonischemic cardiomyopathy underwent FDG-PET/CT for CS diagnosis. We investigated the utility of the new guideline for CS using FDG-PET/CT. Among the 272 patients enrolled, 97 patients were implanted with cardiac pacemakers for AV-b. Twenty-two patients were suspected of having CS during a median observation period of 5.4 years after pacemaker implantation. Of these, one did not consent, and nine of 21 cases (43%) were diagnosed with definite CS according to the new guidelines. Five of these nine patients were diagnosed with iCS using FDG-PET/CT. The number of patients diagnosed with definite CS using the new guidelines tended to be approximately 2.3 times that of the conventional criteria (p = 0.074). Three of the nine patients underwent steroid treatment. The composite outcome, comprising all-cause death, heart failure hospitalization, and a substantial reduction in left ventricular ejection fraction, were significantly lower in patients receiving steroid treatment compared to those without steroid treatment (p = 0.048). The utilization of FDG-PET/CT in accordance with the new guidelines facilitates the diagnosis of CS, including iCS, resulting in approximately 2.3 times as many diagnoses of CS compared to the conventional criteria. This guideline has the potential to support the early identification of iCS and may contribute to enhancing patient clinical outcomes., (© 2024. The Author(s).)

Abstract

Angiotensin receptor-neprilysin inhibitors (ARNI) are effective against heart failure (HF) with reduced ejection fraction, but hypotension is a significant complication. Predictors of ARNI-associated hypotension remain unclear. This study aimed to determine predictors of hypotension after administering an ARNI to patients with HF accompanied by ARNI.This retrospective multicenter observational study analyzed data from 138 consecutive patients with HF treated with an ARNI between August 2020 and July 2021. Hypotension attributed to an ARNI after treatment was defined as (A) systolic blood pressure (SBP) below the 1st quartile ≤ 25 mmHg, and as (B) absolute SBP ≤ 103 mmHg. SBP was measured at baseline, after ARNI treatment, at first follow-up as outpatients and on day 7 for inpatients. Presence of atrial fibrillation, and greater BUN/Cr ratio, and SBP at baseline were significant independent predictors for hypotension after ARNI administration on multivariate analyses. Among 43 patients with AF, fine f-waves on electrocardiograms were significantly more prevalent in the hypotensive group.A robust reduction in blood pressure after ARNI administration is associated with AF and elevated BUN/Cr. This highlights the need for caution when administering ARNI to patients with HF.

Abstract

Background: Physiological assessments using fractional flow reserve (FFR) and resting full-cycle ratio (RFR) have been recommended for revascularization decision making. Previous studies have shown a 20% rate of discordance between FFR and RFR. In this context, the correlation between RFR and FFR in patients with renal dysfunction remains unclear. This study examined correlations between RFR and FFR according to renal function. Methods and Results: In all, 263 consecutive patients with 370 intermediate lesions were enrolled in the study. Patients were classified into 3 groups according to renal function: Group 1, estimated glomerular filtration rate (eGFR) ≥60 mL/min/1.73 m 2 ; Group 2, 30 mL/min/1.73 m 2 ≤eGFR<60 mL/min/1.73 m 2 ; Group 3, eGFR <30 mL/min/1.73 m 2 . The discordance between FFR and RFR was assessed using known cut-off values for FFR (≤0.80) and RFR (≤0.89). Of the 370 lesions, functional significance with FFR was observed in 154 (41.6%). RFR was significantly correlated with FFR in all groups (Group 1, R 2 =0.62 [P<0.001]; Group 2, R 2 =0.67 [P<0.001]; Group 3, R 2 =0.46 [P<0.001]). The rate of discordance between RFR and FFR differed significantly among the 3 groups (Group 1, 18.8%; Group 2, 18.5%; Group 3, 42.9%; P=0.02). Conclusions: The diagnostic performance of RFR differed based on renal function. A better understanding of the clinical factors contributing to FFR/RFR discordance, such as renal function, may facilitate the use of these indices., Competing Interests: The authors have no conflicts of interest to declare., (Copyright © 2022, THE JAPANESE CIRCULATION SOCIETY.)
