Antithrombotic Treatment May Reduce Mortality Among New-Onset Atrial Fibrillation Patients with Gray-Zone Risk of Stroke.

Int Heart J 2019 Feb 8. Epub 2019 Feb 8.

Division of Cardiology, Department of Medicine, Chung Shan Medical University Hospital and Chung Shan Medical University.

In clinical practice, some atrial fibrillation (AF) patients were classified as having low and moderate stroke risk by the CHADS score (≤ 1) in 2001 but in 2012 they were not truly classified as low risk of stroke according to the CHADS-VASc score (≥ 2) (defined gray zone). Therefore, a treatment gap exists in gray zone AF patients. This study aimed to evaluate whether gray zone AF patients could benefit from reduced all-cause mortality under antithrombotic treatment.

Int Heart J 2019 Jan 20;60(1):108-114. Epub 2018 Nov 20.

Department of Cardiovascular Medicine and Hypertension, Graduate School of Medical and Dental Sciences, Kagoshima University.

Pulmonary hypertension (PH) with pulmonary vascular disease (PVD) is a progressive and debilitating disease associated with increased pulmonary vascular resistance (PVR). Biphasic right ventricular outflow tract (RVOT) Doppler flow is frequently seen in severe PH patients with PVD. In association with hemodynamics, the precise analysis of biphasic RVOT Doppler flow (RVDF) has not been fully elucidated. Read More

Endovascular Therapy Using Diluted Contrast Medium for Critical Limb Ischemia in a Patient with Chronic Kidney Disease.

Int Heart J 2019 Jan 20;60(1):226-230. Epub 2018 Nov 20.

Department of Cardiovascular Medicine, The University of Tokyo Hospital.

A high percentage of patients with critical limb ischemia have concurrent chronic kidney disease (CKD). However, endovascular therapy (EVT) can be problematic in CKD patients. Thus, we developed a method of EVT using digital subtraction angiography (DSA) with diluted contrast medium (low-concentration DSA), wherein DSA parameters were adjusted for diluted contrast angiography (1:10 dilution).

Recruitment of Complete Right Bundle Branch Block by Permanent Para-Hisian Pacing.

Int Heart J 2019 Jan 20;60(1):189-192. Epub 2018 Nov 20.

Department of Cardiovascular Medicine, Faculty of Medical Sciences, University of Fukui.

His-bundle pacing has recently emerged as a means to maintain a physiological ventricular activation and eliminate the risk of pacing-induced myopathy associated with traditional right ventricular pacing. With His-bundle pacing, the exact stimulated structure and resulting excitation wavefront may be highly dependent on the pacing output, dimensions of the stimulatory electrodes, and orientation of the cathode and anode relative to the approximated conduction tissue and surrounding myocardium, owing to the juxtaposition of tissues with very different conduction properties. We herein present an 89-year-old woman with an infra-Hisian conduction disease in whom lower output pacing resulted in pure His-bundle pacing, and higher output pacing resulted in para-Hisian pacing that recruited diseased portions of the conduction system, narrowing the QRS complex.

Feasibility and Safety of Left Atrial Appendage Closure Using the LAmbre Device in Patients with Nonvalvular Atrial Fibrillation with or Without Prior Catheter Ablation.

Int Heart J 2019 Jan 20;60(1):63-70. Epub 2018 Nov 20.

Department of Cardiology, Xinhua Hospital, School of Medicine, Shanghai Jiao Tong University.

Left atrial appendage (LAA) closure (LAAC) has emerged as an alternative therapeutic approach to medical therapy for stroke prevention in patients with nonvalvular atrial fibrillation (NVAF). However, complex LAA anatomy may preclude its use. LAmbre is a new, self-expanding LAA occluder, and is highly adaptable to different LAA morphologies. Read More

Blunted Nighttime Sympathetic Nervous System Response to Stress Among Thai Men with Positive Family History of Sudden Unexplained Nocturnal Death Syndrome.

Int Heart J 2019 Jan 20;60(1):55-62. Epub 2018 Nov 20.

Research Division, Praboromarajchanok Institute for Health Workforce Development, Ministry of Public Health.

Sudden unexplained nocturnal death syndrome (SUNDS) is prominent among northeast Thai men. This study tests the hypothesis that Thai men with positive family history of SUNDS display abnormal diurnal, autonomic nervous system responses to stress. Healthy northeast Thai men (20-49 years old) lived in the same rural area were divided into two groups based on their positive (PF) or negative family (NF1) history of SUNDS. Read More

Variation of Electrocardiogram Features Across Sleep Stages in Healthy Controls and in Patients with Sleep Apnea Hypopnea Syndrome.

Int Heart J 2019 Jan 20;60(1):121-128. Epub 2018 Nov 20.

School of Engineering, Sun Yat-Sen University.

Sleep apnea hypopnea syndrome (SAHS) is an independent risk factor for various cardiovascular diseases. Electrocardiogram (ECG) features such as the RR, PR, QT, QTc, Tpe intervals and the Tpe/QT, Tpe/QTc ratios are used to predict and study cardiovascular diseases. It is not clear whether regular patterns of PR and Tpe-related features across sleep stages exist in SAHSs or healthy controls nor whether sleep stages affect the short- and long-range influences of respiratory events on ECG indices.
