Alterations of endothelium-dependent and -independent regulation of coronary blood flow during heart failure

Autor: Kazuhira Maehara, Tomiyoshi Saito, Shu-ichi Saitoh, Yukio Maruyama, Yuji Oikawa, Takeo Niitsuma, Kazuaki Tamagawa

Publikováno v: American journal of physiology. Heart and circulatory physiology. 282(1)

Conflicting data concerning the changes in basal coronary blood flow and nitric oxide (NO)-releasing capacity in chronic heart failure may be due to different phases or duration of heart failure. To investigate endothelium-dependent and -independent

Augmented basal nitric oxide production contributes to maintenance of coronary blood flow in dogs with pacing-induced heart failure

Autor: Takeo Niitsuma, Kazuhira Maehara, Kazuaki Tamagawa, Shu-ichi Saitoh, Masahiko Sato, Yukio Maruyama, Tomiyoshi Saito, Minoru Mitsugi

Publikováno v: Japanese heart journal. 40(5)

It remains controversial whether basal nitric oxide (NO) production in coronary resistance vessels in heart failure is enhanced or not. A transonic Doppler flow probe was placed around the left anterior descending coronary artery, and complete atriov

Effects of cardiac contraction and increased coronary sinus pressure on the coronary arterial pressure-flow relationship

Autor: Masahiko Sato, Shu-ichi Saitoh, Takeo Niitsuma, Kazuhira Maehara, Yukio Maruyama, Minoru Mitsugi, Tomiyoshi Saito

Publikováno v: Japanese heart journal. 40(3)

Increased coronary sinus (CS) pressure and cardiac contraction impair coronary inflow independently. However, it has not been determined how the coronary pressure-flow relationship is strongly affected by changes in CS pressure in the beating heart c

Effects of cardiac contraction and coronary sinus pressure elevation on collateral circulation

Autor: Minoru Mitsugi, Takeo Niitsuma, Tomiyoshi Saito, Kazuhira Maehara, Yukio Maruyama, Shu-ichi Saitoh, M. Sato

Publikováno v: The American journal of physiology. 271(4 Pt 2)

Controlled coronary sinus occlusion was shown to retard necrosis of ischemic myocardium. To elucidate this mechanism, regional myocardial blood flow measurement was performed with and without coronary sinus pressure elevation to 30 mmHg (CS30). Color

A Case of LA-RA Dissociation with Atrial Tachycardia after Surgical Extirpation of Myxoma

Autor: Nobuo Komatsu, Yuichi Nakamura, Hiroto Takeda, Tomomi Komaba, Yasuchika Takeishi, Atsuro Masuda, Kohko Kanazawa, Takeo Niitsuma, Goro Ishida

Publikováno v: Journal of Arrhythmia. 27:PJ3_005

The patient was sixty-one year old male admitted to our cardiovascular center for treatment of atrial tachycardia after extirpation of myxoma 5 years ago. Baseline ECG at electro-physiological study showed sinus rhythm with complete AV block. Intraca
