Background and Objectives: Conventional risk models may not adequately capture key biological determinants of mortality following transcatheter aortic valve implantation (TAVI), such as inflammation, malnutrition, and immune dysfunction. The Osaka Prognostic Score (OPS), incorporating CRP, albumin, and lymphocyte count, may address this gap. We aimed to evaluate the prognostic value of OPS for predicting in-hospital and one-year all-cause mortality after TAVI. Materials and Methods: In this retrospective single-center cohort study, 244 patients who underwent transfemoral TAVI between December 2022 and January 2024 were analyzed. OPS was calculated at baseline (range: 0–3), and its prognostic value for in-hospital and one-year all-cause mortality was evaluated using multivariable Cox regression, ROC analysis, and restricted cubic spline (RCS) modeling. Results: In-hospital and one-year mortality rates were 11.5% and 21.7%, respectively. Higher OPS scores were significantly associated with mortality in both periods. OPS independently predicted in-hospital mortality (HR: 2.018; 95% CI: 1.632–2.521; p = 0.017) and one-year mortality (HR: 2.125; 95% CI: 1.300–3.473; p = 0.003). ROC analysis yielded AUC values of 0.776 and 0.859 for in-hospital and one-year mortality, respectively. Kaplan–Meier curves revealed significantly reduced survival in patients with higher OPS (log-rank p < 0.001), and RCS analysis demonstrated a significant nonlinear association between increasing OPS values and mortality risk (p < 0.001). Conclusions: OPS is a simple, cost-effective, and biologically relevant prognostic index that independently predicts both in-hospital and one-year mortality following TAVI. By integrating markers of inflammation, nutrition, and immune competence, OPS may offer additional value in risk stratification and support clinical decision-making in this high-risk population.

Recent studies have shown a relation between red blood cell distribution width (RDW) / albumin (RAR) levels and worse outcomes in cases of pulmonary embolism (PE). Simplified pulmonary embolism severity index (sPESI) has been developed from more complex PESI score, predicting the risk of death in patients with acute PE (APE). This study aims to investigate whether RDW-Standard Deviation/Albumin (RDW-SD/Alb) can serve as a useful prognostic marker for APE and enhance the predictive capability of the sPESI. This research is a single-center, retrospective analysis involving patients over 18 years. We enrolled 235 consecutive hospitalized patients with confirmed APE diagnoses. To evaluate the sensitivity and specificity of RDW-SD/Alb, sPESI, and the combined sPESI plus RDW-SD/Alb in predicting 6-month all-cause death, we used Receiver Operating Characteristic (ROC) curves. Additionally, we conducted Kaplan–Meier analysis to assess the impact of elevated RDW-SD/Alb levels (> 13.6) on patient survival time. We utilized multivariate Cox regression analysis to identify independent prognostic factors affecting patients survival. The mortality rate for RDW-SD/Alb > 13.6 group was significantly higher than that for the RDW-SD/Alb ≤ 13.6 group. Area under ROC (AUROC) of sPESI plus RDW-SD/Alb was statistically larger than AUROC of sPESI (p = 0.025). In the fully adjusted model, increased RDW-SD/Alb levels were consistently linked to all-cause mortality within six months of admission. The predictive value of the sPESI for 6-month all-cause death improved when the RDW-SD/Alb > 13.6 parameter was included. RDW-SD/Alb, a novel inflammatory marker, was an independent prognostic factor for predicting 6-month all-cause mortality in patients with APE.

Objective: Right ventricular (RV) overload findings affect the risk classification and treatment approach in acute pulmonary embolism (APE). Recently, it was reported that a new electrocardiography (ECG) parameter, terminal D1S + D3R (T-D1S + D3R) pattern, supported the diagnosis of APE. We aim to search the relationship between T-D1S + D3R pattern and right ventricular dilatation (RVD) in APE. Methods: This single-centre, retrospective study was designed with patients aged > 18 years. We screened 267 patients who underwent transthoracic echocardiography (TTE) because of confirmed APE in our emergency department. This study included 72 patients with RVD and 139 patients without RVD [male 41.7%, median age 73,0 (20.8) years; 49.6% male, median age 64,0 (24.0) years]. We compared T-D1S + D3R between RVD (+) and RVD (-) groups. Results: We determined that RVD (+) group had more patients with the T-D1S + D3R parameter than RVD (-) group [51 (70.8%) vs. 25 (18.0%), p < 0.001]. In the univariate logistic regression analyses S1Q3T3, (in)complete right bundle branch block (RBBB), T-D1S + D3R, D3-V1 T wave inversion (TWI), V1-3/4 TWI, V1-3/4 ST-segment elevation, and frontal QRS-T [f(QRS-T)] angle predicted RVD, while T-D1S + D3R, V1-3/4 ST-segment elevation, and f(QRS-T) angle remained independent predictors of RVD in patients with APE. Conclusions: T-D1S + D3R, a new ECG parameter, was an independent predictor of RVD in patients with APE.

Background: Peripheral artery disease (PAD) is a progressive atherosclerotic disorder affecting lower extremities. While anatomical classification systems like Trans-Atlantic Inter-Society Consensus (TASC) aid procedural planning, they lack systemic prognostic components. The Osaka Prognostic Score (OPS), incorporating C-reactive protein, albumin, and lymphocyte count, is an emerging biomarker-based index that may aid in stratifying PAD severity. This study aimed to evaluate whether OPS is associated with infrapopliteal lesion complexity and to determine its predictive value for procedural technical success in patients undergoing endovascular intervention. Methods: This retrospective study included 154 patients undergoing lower extremity percutaneous transluminal angioplasty. Procedures were performed using standard femoral access under fluoroscopic guidance. Technical success was defined as
