Fulminant myocarditis (FM) presents various abnormal findings on ECG, the prognostic impact of which has not been fully elucidated. The aim this study was therefore to clarify value ECG data in FM patients supported by venoarterial extracorporeal membrane oxygenation (VA-ECMO).Methods and Results:In multicenter chart review, we investigated 99 with VA-ECMO. final cohort consisted 87 (mean age, 52±16 years; female, 42%) after 12 who required conversion other forms mechanical circulatory...

Cardiac recovery and prevention of end-organ damage are the cornerstones establishing successful bridge to (BTR) in patients with fulminant myocarditis (FM) supported percutaneous venoarterial extracorporeal membrane oxygenation (VA-ECMO). However, timing method BTR prediction still remain unclear. We aimed develop a model for FM VA-ECMO.Methods Results:This was retrospective multicenter chart review enrolling 99 (52±16 years; female, 42%) treated VA-ECMO. The S-group comprised who...
The effect of the sulphur amino acid, taurine, on biochemical changes induced by a toxic dose isoprenaline was examined in chick hearts. Isoprenaline treatment (80 and 240 mg·kg−1 subcutaneously twice day for four days) caused dependent increase heart to body weight ratio. administration substantial accumulation calcium profound decrease adenosine triphosphate content creatine phosphokinase activity myocardium. A pronounced lipoperoxide phospholipid reduced glutathione concentrations were...
Hemodynamic parameters at rest are known to correlate poorly with peak oxygen uptake (VO2) in heart failure. However, we hypothesized that hemodynamic could predict exercise capacity patients left ventricular assist device (LVAD), because LVAD pump rotational speed does not respond during exercise. Therefore, investigated the relationships between (measured right catheterization) and cardiopulmonary testing) implantable LVAD.We performed a retrospective medical record review of who received...
The acute haemodynamic effects of taurine were studied in normal and beta blocker (propranolol) or calcium antagonist (diltiazem) treated rabbits with experimentally produced chronic aortic regurgitation. administration (25 mg.kg-1) did not affect heart rate left ventricular end diastolic pressure but significant increases dP/dtmax, cardiac output, systolic control hearts, indicating that intravascularly administered substantially increased performance. In propranolol (1 significantly...
Recently, it has become increasingly recognized that pulmonary hypertension (PH) is a particularly threatening result of left-sided heart disease. However, there have been few investigations the impact cardiopulmonary exercise testing (CPX) variables on PH in dilated cardiomyopathy (DCM). We evaluated usefulness crucial CPX for detecting elevated arterial pressure (PAP) patients with DCM.Ninety subjects DCM underwent cardiac catheterization and at our hospital. Receiver operator...
Abstract The spleen has been recognized as an important organ that holds a reserve of 20% to 30% the total blood volume. Spleen contraction and splenic volume reduction occur in patients with hypovolemic shock. However, change association between size hemodynamic parameters remain unclear advanced heart failure (HF) who need left ventricular assist device (LVAD) support. This study was performed investigate relationship before after LVAD implantation HF. We enrolled 20 HF on All underwent...
The clinical significance of worsening renal function (WRF) in elderly patients with acute decompensated heart failure (ADHF) is not completely understood. We compared the conditions between younger and ADHF after appearance WRF to establish its prognostic influence.We included 654 consecutive (37% women) admitted for ADHF. divided into four groups according their age (<80 years, under-80, n=331; ≥80 over-80, n=323) statuses (either or non-WRF group). defined as an increase serum creatinine...
Fast-progressing vascular calcification (VC) is accompanied by renal atrophy and functional deterioration along with atherosclerosis in patients chronic kidney disease (CKD). However, the relationship between VC progression and/or morphological changes remains unclear.We included 70 asymptomatic CKD without hemodialysis our study. To identify temporal variations, coronary artery score (CACS), abdominal aortic index (ACI), parenchymal volume (RPVI) were determined via spiral computed...
An abnormal circadian blood pressure (BP) profile is considered a risk factor for cardiovascular disease. However, its significance in heart failure patients with nonischemic etiology unknown. Herein, we investigated the prognostic value of BP dilated cardiomyopathy (NIDCM).We enrolled 114 NIDCM (76 males, mean age 53.1 years). The percent nighttime fall (%NBPF) was defined using ambulatory monitoring as decrease systolic from daytime. All were divided into three groups: dipper (%NBPF ≥10),...
