Hara H, Igarashi T, Kaida T, Murakami M, Ito H, Niwano S, et al.
Int J Cardiovasc Imaging . 2023 Mar; 39(7):1251-1262. PMID: 36971867
Evaluation of longitudinal strain (LS) from two-dimensional echocardiography is useful for global and regional left ventricular (LV) dysfunction assessment. We determined whether the LS reflects contraction process in patients with...

J Arrhythm . 2022 Jul; 38(3):386-394. PMID: 35785369
Background: Each direct oral anticoagulant (DOAC) has different dose reduction criteria. Here, we evaluated the differences in the doses of three anti-Xa DOACs and clinical events based on the dose...

Nakamura H, Niwano S, Fukaya H, Kishihara J, Satoh A, Oikawa J, et al.
Heart Vessels . 2021 Nov; 37(6):1027-1033. PMID: 34799789
Background: Atrial fibrillation (AF) is associated with an increased risk of heart failure (HF), stroke, and death. Although fibrillation cycle length (FCL) is used as a surrogate for atrial refractoriness,...

J Am Heart Assoc . 2021 Jan; 10(2):e017483. PMID: 33399004
Background Recent clinical trials have demonstrated the possible pleiotropic effects of SGLT2 (sodium-glucose cotransporter 2) inhibitors in clinical cardiovascular diseases. Atrial electrical and structural remodeling is important as an atrial...

Yoshizawa T, Niwano S, Fukaya H, Saitoh D, Fujiyoshi K, Nakamura H, et al.
J Cardiol Cases . 2019 Jul; 20(1):27-29. PMID: 31320950
It is known that the efficacy of catheter ablation for atrial fibrillation (AF) is high, but cardiac tamponade may occur in 1-2% cases. Even in such cases, fatal condition can...

Nakamura H, Niwano S, Niwano H, Fukaya H, Murakami M, Kishihara J, et al.
Heart Vessels . 2019 Feb; 34(8):1389-1393. PMID: 30762094
We have shown that a dipeptidyl peptidase 4 (DPP-4) inhibitor suppresses atrial remodeling in a canine atrial fibrillation (AF) model. Glucagon-like peptide-1 (GLP-1) is increased by DPP-4 inhibitors. However, it...

Ishizue N, Niwano S, Niwano H, Oikawa J, Nakamura H, Hashikata T, et al.
Int Heart J . 2019 Feb; 60(2):411-418. PMID: 30745531
The effect of DPP-4 inhibitor on the electrical and structural remodeling in myocardial injury has not been evaluated. We hypothesized that linagliptin, DPP-4 inhibitor, suppresses myocardial remodeling in the isoproterenol...

Yoshizawa T, Niwano S, Niwano H, Tamaki H, Nakamura H, Igarashi T, et al.
Int Heart J . 2018 Aug; 59(5):1077-1085. PMID: 30158379
In a canine rapid atrial stimulation model of atrial fibrillation (AF), we have demonstrated an increased production of reactive oxygen species (ROS) along with electrical and structural remodeling. In the...

Igarashi T, Niwano S, Niwano H, Yoshizawa T, Nakamura H, Fukaya H, et al.
Heart Vessels . 2018 May; 33(10):1258-1265. PMID: 29721673
Dipeptidyl peptidase 4 (DPP-4) inhibitors have recently been reported to exhibit additional cardioprotective effects; however, their effect in atrial remodeling, such as in atrial fibrillation (AF), remains unclear. In this...

Kishihara J, Niwano S, Fukaya H, Nishinarita R, Horiguchi A, Nakamura H, et al.
J Arrhythm . 2017 Dec; 33(6):637-639. PMID: 29255515
Ventricular capture management is an automatic pacing threshold adjustment algorithm that automatically measures pacing threshold through detection of the evoked response after a pacing stimulus. Although it is principally designed...
