Yasushi Matsuzawa,Masaaki Konishi,Masaaki Konishi,Eiichi Akiyama,Eiichi Akiyama,Hiroyuki Suzuki,Naoki Nakayama,Naoki Nakayama,Masayoshi Kiyokuni,Shinichi Sumita,Toshiaki Ebina,Masami Kosuge,Kiyoshi Hibi,Kengo Tsukahara,Noriaki Iwahashi,Mitsuaki Endo,Nobuhiko Maejima,Kenichiro Saka,Katsutaka Hashiba,Kozo Okada,Masataka Taguri,Satoshi Morita,Seigo Sugiyama,Hisao Ogawa,Hironobu Sashika,Satoshi Umemura,Kazuo Kimura +26 more
TL;DR: Among patients with ST-segment elevation myocardial infarction, slow gait speed was significantly associated with an increased risk of cardiovascular events.
Journal ArticleDOI
Relationship Between Thickness of Calcium on Optical Coherence Tomography and Crack Formation After Balloon Dilatation in Calcified Plaque Requiring Rotational Atherectomy
Nobuhiko Maejima,Kiyoshi Hibi,Kenichiro Saka,Eiichi Akiyama,Masaaki Konishi,Mitsuaki Endo,Noriaki Iwahashi,Kengo Tsukahara,Masami Kosuge,Toshiaki Ebina,Satoshi Umemura,Kazuo Kimura +11 more
TL;DR: Estimation of the effects of rotational atherectomy and subsequent balloon angioplasty on calcified coronary lesions using optical coherence tomography found presence of calcium crack was the important determinant of optimal stent expansion.
Journal ArticleDOI
Association between blood glucose variability and coronary plaque instability in patients with acute coronary syndromes
Kozo Okada,Kiyoshi Hibi,Masaomi Gohbara,Shunsuke Kataoka,Keiko Takano,Eiichi Akiyama,Yasushi Matsuzawa,Kenichiro Saka,Nobuhiko Maejima,Mitsuaki Endo,Noriaki Iwahashi,Kengo Tsukahara,Masami Kosuge,Toshiaki Ebina,Peter J. Fitzgerald,Yasuhiro Honda,Satoshi Umemura,Kazuo Kimura +17 more
TL;DR: Among all glucose indicators studied, only higherBlood glucose variability was an independent determinant of increased lipid and decreased fibrous contents with larger plaque burden, suggesting blood glucose variability as one of the important factors related to coronary plaque vulnerability.
Journal ArticleDOI
Renin-angiotensin system inhibitors and the severity of coronavirus disease 2019 in Kanagawa, Japan: a retrospective cohort study.
Yasushi Matsuzawa,Hisao Ogawa,Kazuo Kimura,Masaaki Konishi,Jin Kirigaya,Kazuki Fukui,Kengo Tsukahara,Hiroyuki Shimizu,Keisuke Iwabuchi,Yu Yamada,Kenichiro Saka,Ichiro Takeuchi,Toshio Hirano,Kouichi Tamura +13 more
TL;DR: Older age was a significant contributor to a worse prognosis in COVID-19 patients, and ACEIs/ARBs could be beneficial for the prevention of confusion in patients with hypertension, a multicenter retrospective observational study.
Journal ArticleDOI
Morphological features of non-culprit plaques on optical coherence tomography and integrated backscatter intravascular ultrasound in patients with acute coronary syndromes
Nobuhiko Maejima,Kiyoshi Hibi,Kenichiro Saka,Naoki Nakayama,Yasushi Matsuzawa,Mitsuaki Endo,Noriaki Iwahashi,Jun Okuda,Kengo Tsukahara,Yoshio Tahara,Masami Kosuge,Toshiaki Ebina,Satoshi Umemura,Kazuo Kimura +13 more
TL;DR: Plaques of non-culprit vessels in patients with ACS had a thinner fibrous cap and a higher percentage of lipid content than culprit plaques in patientsWith stable angina pectoris, plaque compositions were not significantly different between the groups.
