Background: Few studies have compared the Barthel Index (BI) score and postoperative outcomes of transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR). We aimed to examine the relationship between the BI score and postoperative outcomes in patients who underwent TAVR and SAVR.Methods and Results: The study included patients who underwent SAVR between January 2014 and December 2022 (n=293) and patients who underwent TAVR between January 2016 and December 2022 (n=312). We examined the risk factors for long-term mortality in the 2 groups. The mean (±SD) preoperative BI score was 88.7±18.0 in the TAVR group and 95.8±12.3 in the SAVR group. The home discharge rate was significantly lower in the SAVR than TAVR group. The BI score at discharge was significantly higher in the SAVR than in TAVR group (86.2 vs. 80.2; P<0.001). Significant risk factors for long-term mortality in the TAVR group were sex (P<0.001) and preoperative hemoglobin level (P=0.008), whereas those in the SAVR group were preoperative albumin level (P=0.04) and postoperative BI score (P=0.02). The cut-off point of the postoperative BI score determined by receiver operating characteristic curve analysis was 60.0.Conclusions: The BI score at discharge was a significant risk factor for long-term mortality in the SAVR group, with a cut-off value of 60.0.

Background:Secondary hyperparathyroidism develops as a compensatory response to chronic heart failure (HF) and renal failure. The role of parathyroid hormone (PTH) level in acute decompensated HF remains unclear. The aim of this study was therefore to investigate the relationships among mortality, renal function, and serum PTH level in acute decompensated HF patients.Methods and Results:A total of 266 consecutive patients admitted for acute decompensated HF without acute coronary syndrome (78±12 years; 48% male) were enrolled. Demographic, clinical, and laboratory characteristics were obtained on admission.During 1-year follow-up, 65 patients (24%) died. Serum PTH level on admission was within the normal range (10–65 pg/ml) in 108 patients (41%), of whom 39 (15%) had low-normal PTH (10–40 pg/ml). On Kaplan-Meier analysis all-cause mortality was significantly higher in patients with low-normal PTH than in those with high-normal (40–65 pg/ml) or high (>65 pg/ml) PTH (log-rank test). On univariate and multivariate Cox regression analysis, low-normal PTH was significantly associated with increased all-cause mortality (unadjusted HR, 2.88; 95% CI: 1.69–4.91; P<0.001; adjusted HR, 3.84; 95% CI: 1.54–9.57; P=0.004).Conclusions:In patients with acute decompensated HF resulting in hospitalization, low-normal PTH on admission is associated with increased all-cause mortality, regardless of renal function.

Aim: Coronary computed tomography angiography (CCTA)-derived fractional flow reserve (FFRCT) accurately diagnoses ischemic lesions of intermediate stenosis severity. However, significant determinants of FFRCT have not been fully evaluated.Methods: This was a sub-analysis of the Treatment of Alogliptin on Coronary Atherosclerosis Evaluated by Computed Tomography-Based Fractional Flow Reserve trial. Thirty-nine diabetic patients (117 vessels) with intermediate coronary artery stenosis [percent diameter stenosis (%DS) <70%] in whom FFRCT was measured were included in this study. CCTA-defined, vessel-based volumetric and morphological characteristics of plaques were examined to determine their ability to predict FFRCT.Results: Patient-based, multivariate linear regression analysis showed that hemoglobinA1c, triglycerides, and the estimated glomerular filtration rate were significant independent factors associated with FFRCT. Vessel-based, univariate linear regression analysis showed that the total atheroma volume (r=−0.233, p=0.01) and the percentage atheroma volume (PAV) (r=−0.284, p=0.002) as well as %DS (r=−0.316, p=0.006) were significant determinants of FFRCT. Among the plaque components, significant negative correlations were observed between FFRCT and low- (r=−0.248, p=0.007) or intermediate-attenuation plaque volume (r=−0.186, p=0.045), whereas calcified plaque volume was not associated with FFRCT. In the left anterior descending coronary artery (LAD), the plaque volume of each component was associated with FFRCT.Conclusions: Plaque volume, PAV, and %DS were significant determinants of FFRCT. Plaque morphology, particularly in LAD, was associated with FFRCT in diabetic patients with intermediate coronary artery stenosis.
