BACKGROUND: Although the mainstay of treatment for acute decompensated heart failure (ADHF) is decongestion by diuretic therapy, it is often associated with worsening renal function (WRF). The effect of tolvaptan, a selective V2 receptor antagonist, on WRF in ADHF patients with preserved left ventricular ejection fraction (LVEF) is unknown.Methods and Results:We enrolled 50 consecutive ADHF patients whose LVEF on admission was ≥45%. Patients were randomly assigned to either tolvaptan add-on (n=26) or conventional diuretic therapy (n=24)...

BACKGROUND: Heart failure (HF) is a disease of neurohumoral dysfunction and current pharmacological therapies for HF have not improved mortality rates, thus requiring additional new strategies. Waon therapy for HF patients may be a complementary strategy with peripheral vasodilation via nitric oxide. We hypothesized that Waon therapy would improve neurohumoral factors, such as natriuretic peptides (NP) and the renin-angiotensin-aldosterone system (RAAS) in HF.Methods and Results:Plasma samples were collected from patients enrolled in the WAON-CHF Study (Waon therapy (n=77) or control (n=73)) before and after the treatment...

BACKGROUND: Atrial arrhythmias (AAs) are frequent after lung transplantation (LT) and late postoperatively. Several predictive factors of early postoperative AAs after LT have been identified but those of late AAs remain unknown. Whether AA after LT affects mortality is still being debated. This study assessed in a large cohort of LT patients the incidence of AAs early and late after surgery, their predictive factors and their effect on mortality.Methods and Results:We studied 271 consecutive LT patients over 9 years...

BACKGROUND: This paper examines the current status of radiation exposure to patients in myocardial perfusion imaging (MPI) in Asia.Methods and Results:Laboratories voluntarily provided information on MPI performed over a 1-week period. Eight best practice criteria regarding MPI were predefined by an expert panel. Implementation of ≥6 best practices (quality index [QI] ≥6) was pre-specified as a desirable goal for keeping radiation exposure at a low level. Radiation effective dose (ED) in 1,469 patients and QI of 69 laboratories in Asia were compared against data from 239 laboratories in the rest of the world (RoW)...

BACKGROUND: Balloon aortic valvuloplasty (BAV) is resurging as a bridge treatment in patients with severe aortic stenosis (AS) with a dissemination of transcatheter aortic valve implantation. However, the significantly high periprocedural mortality and complication rates still limit the indications of BAV. Further efforts are needed to improve the safety and efficacy of BAV.Methods and Results:We retrospectively investigated the safety and efficacy of simultaneous biplane mode of 3-dimensional transesophageal echocardiography (biplane-TEE) guided antegrade transseptal multiple-inflation BAV, with gradual upsizing of the balloon, by enrolling 20 consecutive AS patients who underwent BAV...

BACKGROUND: Patients with liver cirrhosis (LC) have a higher risk for cardiac surgery, but population-based long-term follow-up studies are lacking. The aim of this study was therefore to validate the long-term outcome of cardiac surgery in patients with LC.Methods and Results:Data were obtained from Taiwan's National Health Insurance Database, 1997-2011. This study included 1,040 LC patients and 1,040 matched controls without LC. The actuarial survival rate at 1, 5 and 10 years in the LC cohort was 68%, 50% and 41%: significantly lower than that of the control cohort at 81%, 68% and 62% at 1, 5 and 10 years after cardiac surgery...

BACKGROUND: We are now facing rapid population aging in Japan, which will affect the actual situation of cardiovascular diseases. However, age-specific trends in the incidence and mortality of acute myocardial infarction (AMI) in Japan remain to be elucidated.Methods and Results:We enrolled a total of 27,220 AMI patients (male/female 19,818/7,402) in our Miyagi AMI Registry during the past 30 years. We divided them into 4 age groups (≤59, 60-69, 70-79 and ≥80 years) and examined the temporal trends in the incidence and in-hospital mortality of AMI during 3 decades (1985-1994, 1995-2004 and 2005-2014)...
