Journal ArticleDOI
Cardio-Ankle Vascular Index is a Candidate Predictor of Coronary Atherosclerosis
TL;DR: CAVI might be more useful for discriminating the probability of coronary Atherosclerosis than findings of carotid atherosclerosis by high-resolution B-mode ultrasonography by using coronary angiographic findings.
Journal ArticleDOI
Efficacy and safety of periprocedural dabigatran in patients undergoing catheter ablation of atrial fibrillation.
Kenichi Kaseno,Shigeto Naito,Kohki Nakamura,Tamotsu Sakamoto,Takehito Sasaki,Naofumi Tsukada,Mamoru Hayano,Suguru Nishiuchi,Etsuko Fuke,Yuko Miki,Keijiro Nakamura,Eiji Yamashita,Koji Kumagai,Shigeru Oshima,Hiroshi Tada +14 more
TL;DR: Dabigatran at a dose of 110mg twice daily was safe for AF ablation in patients with a relatively low risk of thromboemboli, suggesting that it may become an alternative to warfarin in those patients.
Journal ArticleDOI
Association between Cardio-Ankle Vascular Index and Serum Cystatin C Levels in Patients with Cardiovascular Risk Factor
Keijiro Nakamura,Takuo Iizuka,Mao Takahashi,Kazuhiro Shimizu,Hiroshi Mikamo,Takahiro Nakagami,Masayo Suzuki,Keiichi Hirano,Yuko Sugiyama,Takanobu Tomaru,Yoh Miyashita,Kohji Shirai,Hirofumi Noike +12 more
TL;DR: CAVI was closely associated with cystatin C levels, and results suggest a significant role of arterial stiffness in renal insufficiency in cardiovascular risk factors and coronary artery disease.
Journal ArticleDOI
Combined Dominant Frequency and Complex Fractionated Atrial Electrogram Ablation After Circumferential Pulmonary Vein Isolation of Atrial Fibrillation
Koji Kumagai,Tamotsu Sakamoto,Keijiro Nakamura,Suguru Nishiuchi,Mamoru Hayano,Tatsuya Hayashi,Takehito Sasaki,Kazutaka Aonuma,Shigeru Oshima +8 more
TL;DR: An approach of circumferential pulmonary vein isolation followed by a DF and CFAE site ablation is evaluated for AF ablation atrial substrates with high‐dominant frequency and complex fractionated atrial electrogram sites.
Journal ArticleDOI
Optimal observation time after completion of circumferential pulmonary vein isolation for atrial fibrillation to prevent chronic pulmonary vein reconnections
Kohki Nakamura,Shigeto Naito,Kenichi Kaseno,Naofumi Tsukada,Takehito Sasaki,Mamoru Hayano,Suguru Nishiuchi,Etsuko Fuke,Yuko Miki,Tamotsu Sakamoto,Keijiro Nakamura,Koji Kumagai,Akihisa Kataoka,Hiroyuki Takaoka,Yoshio Kobayashi,Nobusada Funabashi,Shigeru Oshima +16 more
TL;DR: An optimal observation time (≥35 min in this study) to determine whether PVI is successfully completed during the initial CPVI for AF may be needed to prevent a CPVR and subsequent AF recurrence thereafter.
