Aim: This work was designed to investigate the relationship between cardiac outcomes and Naples Prognostic Score (NPS) among heart failure (HF) patients. Materials & methods: This retrospective observational study enrolled 298 consecutive individuals hospitalized for New York Heart Association class 3–4 HF. The primary outcome was all-cause mortality. Secondary outcomes were rehospitalization and in-hospital death. Results: The high NPS group had a statistically greater rate of all-cause mortality (p < 0.001). In Cox regression analysis, integrating NPS considerably improved the performance of the full model over the baseline model (adjusted hazard ratio = 2.28; p = 0.004). Based on time-dependent receiver operating characteristic curve analysis, the NPS model outperformed the baseline and CONUT score models in discriminatory power in predicting the probability of survival. Conclusion: NPS was associated with short- and midterm mortality as well as rehospitalization.

Background The purpose of this meta‐analysis was to evaluate the impact of image integration technique on clinical and procedural outcomes in patients undergoing radiofrequency catheter ablation of atrial fibrillation with a three‐dimensional electroanatomic mapping system. Methods Randomized controlled trials were identified through a systematic literature search of PubMed and CENTRAL databases from inception to April 2020. The primary outcome was arrhythmia recurrence during the follow‐up period. The secondary outcomes were the difference in total procedural time and fluoroscopy time. Results Four studies with a total of 749 patients were included. The pooled result showed no statistically significant difference between the groups with respect to arrhythmia recurrence (RR, 0.75; 95% CI, 0.47‐1.21), fluoroscopy time (MD, −6 minutes; 95% CI, −23.4 to 11.3), and total procedural time (MD, 1.1 minutes; 95% CI, −31.8 to 34.1). Conclusion Image integration to guide radiofrequency catheter ablation for patients with atrial fibrillation does not improve clinical and procedural outcomes.

Purpose An elevated left ventricular (LV) filling pressure is the main finding in heart failure patients with preserved ejection fraction, which is estimated with an algorithm using echocardiographic parameters recommended by the recent American Society of Echocardiography (ASE)/European Association of Cardiovascular Imaging (EACVI) guidelines. In this study, we sought to determine the efficacy of the LV global longitudinal strain (GLS) in predicting an elevated LV filling pressure. Methods and Results A total of 73 prospectively selected patients undergoing LV catheterization (mean age 63.19 ± 9.64, 69% male) participated in this study. Using the algorithm, the LV filling pressure was estimated using the echocardiographic parameters obtained within 24 hours before catheterization. The LV GLS was measured using an automated functional imaging system (GE, Vivid E9 USA). Invasive LV pre‐A pressure corresponding to the mean left atrial pressure (LAP) was used as a reference, and a LAP of >12 mm Hg was defined as elevated. Invasive LV filling pressure was elevated in 43 patients (59%) and normal in 30 patients (41%). Nine of 73 (12%) patients were defined as indeterminate based on the 2016 algorithm. Using the ROC method, −18.1% of LV GLS determined the elevated LAP (AUC =0.79; specificity, 73%; sensitivity, 84%) with better sensitivity compared to that by the algorithm (AUC =0.76; specificity, 77%; sensitivity, 72%). Conclusions We demonstrated that LV GLS was an independent predictor of elevated LAP as the E/e’ ratio and TR jet velocity and may be used as a major criterion for the diagnosis of HFpEF.
