Information regarding sex, age, public insurance, hypertension, diabetes mellitus, dyslipidemia, chronic obstructive pulmonary disease, cancer, dysuria, bronchial asthma, and chronic kidney disease was collected using a patient database created from medical and hospital records. Based on a previous study, subjects who visited the ED four or more times were defined as frequent visitors, while those who visited the ED less than four times were considered infrequent visitors.

Among 2,248 cardiopulmonary arrest patients presenting at our hospital, we retrospectively investigated 110 patients with VF-OHCA who were admitted for treatment. We divided the patients based on ICD(n=71) or No-ICD status(n=39), and on reversible cause(n=70) or irreversible cause(n=40). The groups were compared for baseline characteristics, mortality and ICD therapies. Patients with a reversible cause had a signi cantly lower rate of ICD implantation than those with an irreversible cause(P=0.03). Males in the ICD group presented more frequently than those in the No-ICD group, and cardiac mortality in patients with acute coronary syndrome was signi cantly lower with ICD therapy than without ICD(P=0.04). The rate of appropriate ICD therapies with a reversible cause was 28%, and the rst ICD therapy was highest within 1 year post-implantation. Patients with VF-OHCA due to a reversible cause remain at high risk of recurrent ventricular arrhythmias, suggesting that ICD implantation is a reasonable approach in such cases.","PeriodicalId":23019,"journal":{"name":"The Showa University Journal of Medical Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87508270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From January 2012 to July 2017, we retrospectively investigated the medical records of patients who were administered AZM by injection at Showa University Fujigaoka Hospital. Vascular pain was related to intensive care unit (ICU) administration (P=0.003) compared with that in general wards and a long duration of administration (P=0.002). The number of days of AZM injection should be kept as short as possible. Given that the risk of injection site pain is increased in the ICU, we recommend switching to oral administration.

However, outcomes differ between paroxysmal AF and persistent AF. We analyzed the predictors of recurrence by examining the recurrence group after ablation. Of 372 consecutive patients with AF who underwent PVI between June 2016 and December 2018, we evaluated 250 patients （ age, 67 (cid:156) 12 y, 65 ％ men ） whose left atrium （ LA ） was constructed using the PENTARAY catheter （ BioSense Webster, Los Angeles, CA ） , a multipolar electrode catheter with a novel shape and excellent mapping capability. We measured the LA total volume （ LATV ） , right pulmonary vein ＋ antrum volume （ RPAV ） , left PV ＋ antrum volume （ LPAV ） , LA central volume （ LACV ） , and LA bipolar voltage. Of the 250 patients, 78 had persistent AF （ recurrence, 20 ） and 172 had paroxysmal AF （ recurrence, 16 ） . In all patients, LATV, LACV, RPAV, and LPAV were significantly larger in patients with persistent AF than those with paroxysmal AF. The mean LA bipolar voltage in patients with persistent AF was significantly lower than those with paroxysmal AF. In cases of persistent AF, RPAV was significantly larger in the recurrence group than that in the non-recurrence group （ 15.9 (cid:156) 4.8 vs 13.4 (cid:156) 5.4 ml; P ＜ 0.05 ） . In cases of paroxysmal AF, there were no differences in any volume between the recurrence and non-recurrence groups. In conclusion, larger right PV is a predictor of AF recurrence after PVI in patients with persistent AF. The right PV is close to the atrial septum and the septopulmonary bundle, and the expansion of RPAV reflects the disruption of these structures, which may be involved in this result.","PeriodicalId":23019,"journal":{"name":"The Showa University Journal of Medical Sciences","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85518267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
