    Abstract: Coronary arterial aneurysms (CAAs) associated with Kawasaki disease (KD) significantly affect prognosis. However, the clinical course of CAAs and factors associated with CAA regression have not been well analyzed. Methods and Results The cohort of the Z‐Score 2nd Project Stage study, a multicenter, retrospective, cohort study involving 44 institutions in Japan including 1006 patients with KD, was examined. CAAs were classified by the z score of their internal diameter in the acute phase: small ( z 〈 5), medium (5≤ z 〈 10), and large ( z ≥10). The lower limit of small CAA was based on the Japanese Ministry of Health, Labour and Welfare criteria. In the right coronary artery, the CAA regression rates 10 years after diagnosis were 95.5% for small, 83.2% for medium, and 36.3% for large. In the proximal left anterior descending artery, the regression rates 10 years after diagnosis were 95.3% for small, 80.1% for medium, and 28.8% for large. Cox regression analysis showed that diagnosis under the age of 1 year and onset of KD in 2010 to 2012 for the right coronary artery and the left anterior descending artery, and female for the right coronary artery were significantly associated with a high regression rate, whereas large CAAs for the right coronary artery and the left anterior descending artery were significantly associated with a low regression rate. Conclusions The current study, the largest Japanese study of its kind, found that small aneurysm, recent onset, and diagnosis under the age of 1 year predict regression, and that even giant aneurysms could regress. These data may contribute to long‐term management of coronary aneurysms. Registration URL: https://www.umin.ac.jp/ctr/ ; Unique identifier: UMIN000010606.

    Abstract: Fulminant myocarditis presentation (FMP) is a rare and severe presentation of myocarditis. The natural history of FMP and its clinical features associated with poor outcomes are incompletely understood because there is a lack of generalizable evidence. Methods: This multicenter retrospective cohort study included patients hospitalized with histologically proven myocarditis who underwent catecholamine or mechanical support from 235 cardiovascular training hospitals across Japan between April 2012 and March 2017. Clinical features and the prognostic predictors of death or heart transplantation within 90 days on the basis of clinical and pathologic findings were determined using the Kaplan-Meier method, log-rank test, and Cox regression analysis. Results: This study included 344 patients with histologically proven FMP (median age, 54 years; 40% female). The median follow-up was 600 days (interquartile range, 36 to 1599 days) and the cumulative risk of death or heart transplantation at 90 days was 29% (n=98). Results from multivariable Cox regression analysis showed that older age, nonsinus rhythm, low left ventricular wall motion ( 〈 40%) on admission, and ventricular tachycardia or fibrillation on admission day were associated with worse 90-day survival. Severe histologic damage (damaged cardiomyocytes comprising ≥50% of the total cardiomyocytes) was associated with a worse 90-day prognosis in patients with lymphocytic myocarditis. Conclusions: The results from analyses of data from this multicenter registry demonstrated that patients with FMP are at a higher risk of death or heart transplantation in real-world settings. These observations inform which clinical and pathologic findings may be useful for prognostication in FMP. Registration: URL: https://www.umin.ac.jp/ctr ; Unique identifier: UMIN000039763.

    Abstract: To report the distinctive clinical features of cryptogenic new-onset refractory status epilepticus (C-NORSE) and the C-NORSE score based on initial clinical assessments. Methods: A retrospective study was conducted for 136 patients with clinically suspected autoimmune encephalitis who underwent testing for autoantibodies to neuronal surface antigens between January 1, 2007, and August 31, 2016. Eleven patients with C-NORSE were identified. Their clinical features were compared with those of 32 patients with anti-NMDA receptor encephalitis (NMDARE). Results: The clinical outcome of 11 patients (median age, 27 years; 7 [64%] women) with C-NORSE was evaluated after a median follow-up of 11 months (range, 6–111 months). Status epilepticus was frequently preceded by fever (10/11 [91%] ). Brain MRIs showed symmetric T2/fluid-attenuated inversion recovery hyperintensities (8/11 [73%]) and brain atrophy (9/11 [82%] ). Only 2 of the 10 treated patients responded to the first-line immunotherapy, and 4 of the 5 patients treated with IV cyclophosphamide responded to the therapy. The long-term outcome was poor in 8 patients (73%). Compared with 32 patients with NMDARE (median age, 27 years; 24 [75%] women), those with C-NORSE had more frequent prodromal fever, status epilepticus, ventilatory support, and symmetric brain MRI abnormalities, had less frequent involuntary movements, absent psychobehavioral symptoms, CSF oligoclonal bands, or tumor association, and had a worse outcome. The C-NORSE score was higher in patients with C-NORSE than those with NMDARE. Conclusions: Patients with C-NORSE have a spectrum of clinical-immunological features different from those with NMDARE. The C-NORSE score may be useful for discrimination between them. Some patients could respond to immunotherapy.

    Abstract: Introduction: The severity of coronary artery aneurysms (CAA) in patients with Kawasaki disease (KD) has been recently classified according to the z-score. However, it is not known whether this classification can predict coronary events such as stenosis, obstruction, and thrombosis. Methods: In this multicenter retrospective study, data on height, weight, CAA diameter measured by echocardiography in the acute phase, and the clinical course in KD patients 18 years of age or younger who received a coronary angiography between 1992 and 2011 were collected. Time-dependent occurrence of coronary events was analyzed by Kaplan-Meier method according to small (z-score, 〈 5.0), medium (≥ 5.0 to 〈 10.0), and large (≥ 10.0) CAA using a 5 increment scale scheduled to be included in the new American Heart Association criteria. Cox regression analysis was used to identify risk factors for coronary events. The occurrence rate of major cardiac events such as angina pectoris, myocardial infarction, and cardiac death was also analyzed. Results: Data were analyzed for 1,002 patients from 44 institutions. Both the body surface area and CAA diameters were available in 741 cases for the right coronary artery (RCA) and 609 cases for the left anterior descending artery (LAD). Coronary events occurred in 83 (11.2%) of the RCA group and 57 (9.4%) of the LAD group, while major events occurred in 30 cases (3.0%). The 10-year event-free survival rate for coronary events for small, medium, and large aneurysms was 100, 95.5, and 64.9% in the RCA group, and 100, 94.4, and 63.5% for aneurysms in the LAD group, respectively. The rate of major cardiac events was 98.5, 98.1, and 87.6% for the RCA group, and 100, 97.5, and 86.8% for the LAD group, respectively. Cox regression analyses showed that the z-score of the CAA diameter was an independent risk factor for coronary events for the RCA [large versus medium aneurysm; hazard ratio (HR) 2.8, 95% confidence interval (CI) 1.5 to 5.3, p = 0.002] and the LAD [HR 3.2, 95% CI 1.6 to 6.5, p = 0.015] groups. Conclusions: The severity assessment of CAA using the 5-increment z-score for coronary arterial diameter can predict the time-dependent occurrence of coronary events in patients with KD.

    Abstract: Recently, surgical robotic systems have been used to perform microsurgery. Surgical robots have certain properties that make them well suited to microsurgery; for example, they possess 3-dimensional vision, which can be magnified up to 25 times; their movements are up to 5 times more precise than those of surgeons; they possess 7 degrees of wrist articulation; they do not suffer from physiologic tremors; and they can achieve ergonomic surgical positions. The purpose of this study was to report the feasibility of robot-assisted intercostal nerve harvesting in a clinical case. A healthy 57-year-old man suffered a left plexus injury. On diagnosis of clavicular brachial plexus injury, the intercostal nerve transfer to the muscular cutaneous nerve to restore elbow flexion was performed with Da Vinci Xi robot. The harvesting of intercostal nerves using the conventional open approach involves significant surgical exposure, which can lead to perioperative complications. Robot-assisted intercostal nerve harvesting might reduce postoperative pain, shorten patients’ hospital stays, lower complication rates, and produce better quality-of-life outcomes. There are many issues to be solved when performing robotic surgery on peripheral nerves in Japan. However, robot-assisted intercostal nerve harvesting was a feasible surgical procedure, and patient satisfaction was high.

    Abstract: Resistant hypertension is an important cardiovascular risk factor. This analysis of the JAMP study (Japan Ambulatory Blood Pressure Monitoring Prospective) data investigated the effects of uncontrolled resistant hypertension diagnosed using ambulatory blood pressure (BP) monitoring on the risk of heart failure (HF) and overall cardiovascular events. The JAMP study patients with hypertension and no HF history were included. They had true resistant hypertension (24-hour BP ≥130/80 mm Hg), pseudoresistant hypertension (24-hour BP 〈 130/80 mm Hg), well-controlled nonresistant hypertension (24-hour BP 〈 130/80 mm Hg), or uncontrolled nonresistant hypertension (24-hour BP ≥130/80 mm Hg). The primary end point was total cardiovascular events, including atherosclerotic cardiovascular disease (fatal/nonfatal stroke and fatal/nonfatal coronary artery disease), and HF. During 4.5±2.4 years of follow-up the overall incidence per 1000 person-years was 10.1 for total cardiovascular disease, 4.1 for stroke, 3.5 for coronary artery disease, and 2.6 for HF. The adjusted risk of total cardiovascular and HF events was significantly increased in patients with true resistant versus controlled nonresistant hypertension (hazard ratio, 1.66 [95% CI, 1.12–2.48] ; P =0.012 and 2.24 [95% CI, 1.17–4.30]; P =0.015, respectively) and versus uncontrolled nonresistant hypertension (1.51 [1.03–2.20]; P =0.034 and 3.03 [1.58–5.83]; P 〈 0.001, respectively). The findings were robust in a sensitivity analysis using a slightly different definition of resistant hypertension. True resistant hypertension diagnosed using ambulatory BP monitoring is a significant independent risk factor for cardiovascular disease events, especially for HF. This highlights the importance of diagnosing and effectively treating resistant hypertension. Registration: URL: https://www.umin.ac.jp/ctr ; Unique identifier: UMIN000020377.

    Abstract: High blood pressure increases bleeding risk during treatment with antithrombotic medication. The association between blood pressure levels and the risk of recurrent stroke during long-term secondary stroke prevention with thienopyridines (particularly prasugrel) has not been well studied. Methods: This was a post hoc analysis of the randomized, double-blind, multicenter PRASTRO-I trial (Comparison of Prasugrel and Clopidogrel in Japanese Patients With Ischemic Stroke-I). Patients with noncardioembolic stroke were randomly assigned (1:1) to receive prasugrel 3.75 mg/day or clopidogrel 75 mg/day for 96 to 104 weeks. Risks of any ischemic or hemorrhagic stroke, combined ischemic events, and combined bleeding events were determined based on the mean level and visit-to-visit variability, including successive variation, of systolic blood pressure (SBP) throughout the observational period. These risks were also compared between quartiles of mean SBP level and successive variation of SBP. Results: A total of 3747 patients (age 62.1±8.5 years, 797 women), with a median average SBP level during the observational period of 132.5 mm Hg, were studied. All the risks of any stroke (146 events; hazard ratio, 1.318 [95% CI, 1.094–1.583] per 10-mm Hg increase), ischemic stroke (133 events, 1.219 [1.010–1.466] ), hemorrhagic stroke (13 events, 3.247 [1.660–6.296]), ischemic events (142 events, 1.219 [1.020–1.466] ), and bleeding events (47 events, 1.629 [1.172–2.261]) correlated with increasing mean SBP overall. Similarly, an increased risk of these events correlated with increasing successive variation of SBP (hazard ratio, 3.078 [95% CI, 2.220–4.225] per 10-mm Hg increase; 3.051 [2.179–4.262]; 3.276 [1.172–9.092] ; 2.865 [2.042–4.011]; 2.764 [1.524–5.016] , respectively). Event rates did not differ between the clopidogrel and prasugrel groups within each quartile of SBP or successive variation of SBP. Conclusions: Both high mean SBP level and high visit-to-visit variability in SBP were significantly associated with the risk of recurrent stroke during long-term medication with either prasugrel or clopidogrel after stroke. Control of hypertension would be important regardless of the type of antiplatelet drugs. Registration: URL: https://www.clinicaltrials.jp ; Unique identifier: JapicCTI-111582.

    Abstract: Background In patients with Stanford type B dissection who have been treated successfully with medical hypotensive therapy during the acute phase, a large number have incurred the risk of surgery during their chronic phases because of enlargement of the dissected aorta. The purpose of this study was to determine the indications for surgical treatment of acute type B dissection by studying chronic-phase enlargements of aortic dissections in patients treated successfully with medical hypotensive therapy during the acute phase. Methods and Results In 41 patients with type B dissection who had been treated medically during the acute phase, univariate and multivariate factor analyses were made to determine the predominant predictors for chronic-phase enlargement (≥60 mm) of the dissected aorta. Computed tomography was performed every 4 to 14 months to observe whether there was enlargement of the maximum aortic diameter. The predominant predictors for aortic enlargement in the chronic phase were the existence of a maximum aortic diameter of ≥40 mm during the acute phase ( P 〈 .001) and a patent primary entry site in the thoracic aorta ( P =.001). The values of actuarial freedom from aortic enlargement for the patients with a large aortic diameter (≥40 mm) during the acute phase and a patent primary entry site in the thorax at 1, 3, and 5 years were 70%, 29%, and 22%, respectively. No aortic enlargement was observed in the other patients throughout the entire follow-up period. Conclusions These data suggest that patients with acute type B dissection who have a large aortic diameter (≥40 mm) and a patent primary entry site in the thorax should be treated surgically during the acute phase on the condition that the surgical risk in this phase is limited.

    Impact of Plasma Oxidized Low-Density Lipoprotein Removal on Atherosclerosis
    Ovid Technologies (Wolters Kluwer Health) ; 2008
    In:  Circulation Vol. 118, No. 1 ( 2008-07), p. 75-83
    Details
    In: Circulation, Ovid Technologies (Wolters Kluwer Health), Vol. 118, No. 1 ( 2008-07), p. 75-83
    Abstract: Background— Several clinical studies of statin therapy have demonstrated that lowering low-density lipoprotein (LDL) cholesterol prevents atherosclerotic progression and decreases cardiovascular mortality. In addition, oxidized LDL (oxLDL) is suggested to play roles in the formation and progression of atherosclerosis. However, whether lowering oxLDL alone, rather than total LDL, affects atherogenesis remains unclear. Methods and Results— To clarify the atherogenic impact of oxLDL, lectin-like oxLDL receptor 1 (LOX-1), an oxLDL receptor, was expressed ectopically in the liver with adenovirus administration in apolipoprotein E–deficient mice at 46 weeks of age. Hepatic LOX-1 expression enhanced hepatic oxLDL uptake, indicating functional expression of LOX-1 in the liver. Although plasma total cholesterol, triglyceride, and LDL cholesterol levels were unaffected, plasma oxLDL was markedly and transiently decreased in LOX-1 mice. In controls, atherosclerotic lesions, detected by Oil Red O staining, were markedly increased (by 38%) during the 4-week period after adenoviral administration. In contrast, atherosclerotic progression was almost completely inhibited by hepatic LOX-1 expression. In addition, plasma monocyte chemotactic protein-1 and lipid peroxide levels were decreased, whereas adiponectin was increased, suggesting decreased systemic oxidative stress. Thus, LOX1 expressed in the livers of apolipoprotein E–deficient mice transiently removes oxLDL from circulating blood and possibly decreases systemic oxidative stress, resulting in complete prevention of atherosclerotic progression despite the persistence of severe LDL hypercholesterolemia and hypertriglyceridemia. Conclusions— OxLDL has a major atherogenic impact, and oxLDL removal is a promising therapeutic strategy against atherosclerosis.
