Carvedilol Decreases Elevated Oxidative Stress in Human Failing Myocardium
Kazufumi Nakamura,Kengo Fukushima Kusano,Yoichi Nakamura,Mikio Kakishita,Keiko Ohta,Satoshi Nagase,Mika Yamamoto,Katsumasa Miyaji,Hironori Saito,Hiroshi Morita,Tetsuro Emori,Hiromi Matsubara,Shinya Toyokuni,Tohru Ohe +13 more
TL;DR: Oxidative stress is elevated in myocardia of patients with heart failure and administration of carvedilol resulted in a decrease in the oxidative stress level together with amelioration of cardiac function.
Journal ArticleDOI
Novel Angiographic Classification of Each Vascular Lesion in Chronic Thromboembolic Pulmonary Hypertension Based on Selective Angiogram and Results of Balloon Pulmonary Angioplasty
Takashi Kawakami,Aiko Ogawa,Katsumasa Miyaji,Hiroki Mizoguchi,Hiroto Shimokawahara,Takanori Naito,Takashi Oka,Kei Yunoki,Mitsuru Munemasa,Hiromi Matsubara +9 more
TL;DR: The outcome and complication rate of the BPA are highly dependent on the lesion characteristics, and a new classification for each vascular lesion is established.
Journal ArticleDOI
Improved survival after living-donor lobar lung transplantation
Hiroshi Date,Motoi Aoe,Yoshifumi Sano,Itaru Nagahiro,Katsumasa Miyaji,Keiji Goto,Masaaki Kawada,Shunji Sano,Nobuyoshi Shimizu +8 more
TL;DR: Living-donor lobar lung transplantation can be applied to both pediatric and adult patients with very limited life expectancies and might provide better survival than conventional cadaveric lung transplants.
Journal ArticleDOI
Relationship between oxidative stress and systolic dysfunction in patients with hypertrophic cardiomyopathy
Kazufumi Nakamura,Kengo Fukushima Kusano,Hiromi Matsubara,Yoichi Nakamura,Aya Miura,Nobuhiro Nishii,Kimikazu Banba,Satoshi Nagase,Katsumasa Miyaji,Hiroshi Morita,Hironori Saito,Tetsuro Emori,Tohru Ohe +12 more
TL;DR: Oxidative stress was elevated in myocardia of HCM patients and the levels were correlated with left ventricular dilatation and systolic dysfunction, suggesting oxidative stress is involved in the pathogenesis of heart failure in patients with HCM.
Journal ArticleDOI
Prednisolone Inhibits Proliferation of Cultured Pulmonary Artery Smooth Muscle Cells of Patients With Idiopathic Pulmonary Arterial Hypertension
Aiko Ogawa,Kazufumi Nakamura,Hiromi Matsubara,Hideki Fujio,Tetsuya Ikeda,Kaoru Kobayashi,Ikuko Miyazaki,Masato Asanuma,Katsumasa Miyaji,Daiji Miura,Kengo Fukushima Kusano,Hiroshi Date,Tohru Ohe +12 more
TL;DR: The results indicate that PSL has an antiproliferative effect on cultured SMCs of pulmonary arteries from patients with IPAH and suggest thatPSL may be potentially useful therapeutically in patients with IPAH.
