The Role of Atrial Premature Complexes in Exercise Test in Predicting Atrial Fibrillation in Patients Without Obstructive Coronary Artery Disease.

BACKGROUND: Atrial fibrillation (AF) is usually triggered by frequent atrial premature complexes (APC) and atrial tachycardias originated in the pulmonary veins. The aim of the current study is to clarify the relationship between AF and APCs observed during treadmill exercise testing through long-term patient follow-up. MATERIAL AND METHODS: Our study only examined the data of patients who did not have any obstructive coronary artery disease and had an exercise test. In total, 1559 patients were included in this research. The study data were divided into two groups according to the development of AF during follow-up. The patients who developed any type of AF during the follow-up period were classified as AF (+). Mean follow-up time for AF (+) and (-) groups were 48 and 47 months, respectively. RESULTS: In the univariable analysis, age, LAAP, and the presence of APCs (HR: 3.906, 95% CI: 2.848-5.365, p < 0.001) during the treadmill exercise test were significantly associated with the development of AF. In the multivariable analysis, age (adjusted HR: 1.063, 95% CI: 1.043-1.083, p < 0.001) and the presence of APCs during the treadmill exercise test (adjusted HR: 2.504, 95% CI: 1.759-3.565, p < 0.001) emerged as independent risk factors for the development of AF. The AF-free survival was significantly lower in the APCs (+) patients compared with the APCs (-) patients (log rank p < 0.001). CONCLUSION: Our study revealed that individuals without obstructive CAD who exhibited frequent APCs during treadmill exercise tests were more likely to develop AF.

Cluster analysis of clinical, angiographic, and laboratory parameters in patients with ST-segment elevation myocardial infarction.

INTRODUCTION: ST-segment elevation myocardial infarction (STEMI) represents the most harmful clinical manifestation of coronary artery disease. Risk assessment plays a beneficial role in determining both the treatment approach and the appropriate time for discharge. Hierarchical agglomerative clustering (HAC), a machine learning algorithm, is an innovative approach employed for the categorization of patients with comparable clinical and laboratory features. The aim of the present study was to investigate the role of HAC in categorizing STEMI patients and to compare the results of these patients. METHODS: A total of 3205 patients who were diagnosed with STEMI at the university hospital emergency clinic between 2015 and 2023 were included in the study. The patients were divided into 2 different phenotypic disease clusters using the HAC method, and their outcomes were compared. RESULTS: In the present study, a total of 3205 STEMI patients were included; 2731 patients were in cluster 1, and 474 patients were in cluster 2. Mortality was observed in 147 (5.4%) patients in cluster 1 and 108 (23%) patients in cluster 2 (chi-square P value < 0.01). Survival analysis revealed that patients in cluster 2 had a significantly greater risk of death than patients in cluster 1 did (log-rank P < 0.001). After adjustment for age and sex in the Cox proportional hazards model, cluster 2 exhibited a notably greater risk of death than did cluster 1 (HR = 3.51, 95% CI = 2.71-4.54; P < 0.001). CONCLUSION: Our study showed that the HAC method may be a potential tool for predicting one-month mortality in STEMI patients.

Prognostic value of pulmonary artery diameter/aorta diameter ratio in patients with acute pulmonary embolism.

BACKGROUND: The ratio of pulmonary artery diameter (PAD) to ascending aortic diameter (AoD) has been reported to be a prognostic marker in several lung diseases; however, the usefulness of this tool in patients with acute pulmonary embolism (APE) is unknown. Here, we aimed to determine the long-term prognostic value of the PAD/AoD ratio in patients with APE. METHODS: A total of 275 patients diagnosed with APE at our tertiary care center between November 2016 and February 2022 were included in the study. The patients were divided into two groups according to the presence of long-term mortality and their PAD/AoD ratios were compared. RESULTS: Long-term mortality was observed in 48 patients during the median follow-up of 59 (39-73) months. The patients were divided into two groups for analysis: group 1, consisting of 227 patients without recorded mortality, and group 2, consisting of 48 patients with documented mortality. A multivariate Cox regression model indicated that the PAD/AoD ratio has the potential to predict long-term mortality (HR: 2.9116, 95% CI: 1.1544-7.3436, p = 0.023). Analysis of the receiver operating characteristic curve revealed that there was no discernible difference in discriminative ability between the simplified pulmonary embolism severity index (sPESI) and PAD/AoD ratio (area under the curve [AUC] = 0.679 vs. 0.684, respectively, p = 0.937). The long-term predictive ability of the PAD/AoD ratio was not inferior to the sPESI score. CONCLUSIONS: The PAD/AoD ratio, which can be easily calculated from pulmonary computed tomography, may be a useful parameter for determining the prognosis of APE patients.

Evaluation of risk factors for long-term atrial fibrillation development in patients undergoing typical atrial flutter ablation: a multicenter pilot study.

BACKGROUND: Atrial flutter (AFL) and atrial fibrillation (AF) are the most commonly detected supraventricular arrhythmias and share similar pathophysiological mechanisms. After the successful ablation of AFL, AF frequently occurs in the long-term follow-up. As emphasized in some studies, certain mechanisms seem to predispose to the development of AF in AFL patients, and approximately 20% of these patients have accompanying AFL. PURPOSE: We aimed to analyze independent risk factors that predict the development of AF in patients who underwent typical AFL ablation. METHODS: This was a multicenter, cross-sectional, and retrospective study. A total of 442 patients who underwent typical AFL ablation at three different centers between January 1, 2018 and January 1, 2022 were included retrospectively. After the ablation procedure the patients were divided into those who developed AF and those who did not. The patients were followed up for an average of 12 (4-20) months. In the post-procedural period, atrial arrhythmias were investigated with 24­h Holter and ECG at 1 month, 6 months, and 12 months and then at 6­month intervals thereafter. RESULTS: Overall, AF developed in 206 (46.6%) patients in the long-term follow-up. Age, hypertension (HT), obstructive sleep apnea syndrome (OSAS), previous cerebrovascular accident (CVA), left atrium anteroposterior diameter, severe mitral regurgitation, hemoglobin, blood glucose, and HbA1c values were found to be significant in univariable analysis. According to multivariable analysis, HT (p = 0.014; HR: 1.483 [1.084-2.030]), OSAS (p = 0.008; HR: 1.520 [1.117-2.068]) and previous CVA (p = 0.038; HR: 1.749 [1.031-2.968]) were independently associated with the development of AF in AFL patients who underwent ablation procedure. CONCLUSION: In the present study, we found that HT, OSAS, and previous CVA were independently correlated with the development of AF in the long-term follow-up of patients who underwent typical AFL ablation. We consider that AFL patients with such risk factors should be followed up closely following cavotricuspid isthmus ablation for the development of AF.

The Association between Exercise-Induced Ventricular Premature Contractions and Long-Term Mortality in Patients without Obstructive Coronary Artery Disease.

Background: The treadmill exercise test is widely used to determine cardiovascular risk and mortality. Premature ventricular complexes (PVCs) are frequently observed during exercise stress testing. The literature on the role of PVCs observed during treadmill exercise testing in predicting prognosis is controversial. Hence, we aimed to evaluate the clinical results of PVCs seen during exercise testing in patients without obstructive coronary artery disease confirmed by coronary angiography (CAG). Methods: The study population consisted of 1624 consecutive patients who were considered high risk according to the Duke treadmill risk score and had no significant stenosis on CAG from January 2016 to April 2021. The primary endpoints of the study were long-term all-cause mortality of patients who had PVCs during the exercise test or during the resting phase. Results: Long-term mortality was observed in 53 of the 1624 patients after a mean follow-up of 47 months. PVCs were observed in 293 (18.7%) patients without long-term mortality, and in 24 (45.3%) patients with long-term mortality (p < 0.001). The model adjusted for all covariates showed that the presence of PVCs in the recovery phase [p < 0.007, hazard ratio (HR) (95% confidence interval (CI)) 2.244 (1.244-4.047)] and advanced age [p < 0.001, HR (95% CI) 1.194 (1.143-1.247)] were associated with long-term all-cause mortality. Conclusions: PVCs observed during treadmill exercise testing and the recovery phase were related to long-term mortality in patients without obstructive coronary artery disease.

Validation of the HCM Risk-SCD model in patients with hypertrophic cardiomyopathy and future perspectives.

BACKGROUND: The hypertrophic cardiomyopathy (HCM) risk- sudden cardiac death (SCD) model provides a convenient tool for determining the risk of SCD in patients with HCM even though some patients with low-risk scores still remain at risk of SCD. Hence, the aim of our study was to assess the performance of HCM Risk-SCD in a large series of consecutive patients with HCM who had been followed up in a tertiary center. METHODS: The study population consisted of 389 consecutive HCM patients who had been followed up between 2004 and 2021. Demographic and clinical characteristics, estimated 5-year risk using the HCM Risk-SCD model, were compiled, and survival data were collected during follow-up. Patients were divided into 2 groups according to their long-term survival, and HCM risk-SCD scores of these two groups were compared. RESULTS: The long-term mortality was observed in 47 patients out of 389 patients in the during a mean follow-up of 55.5 ± 12.7 months. The mean HCM Risk-SCD score of surviving patients was significantly lower than that of non-survivors (1.8% vs. 3.0%, p < .001). The HCM Risk-SCD score was above 6% in nine (2.6%) survivors and nine (19.1%) non-survivors (p < .001). The ROC curve based on the HCM Risk-SCD score had 61% sensitivity and 61% specificity for risk threshold of for 2.0%, 38% sensitivity and 99% specificity a threshold of ≥4%, 17% sensitivity, and 99% specificity for a threshold of ≥6%. CONCLUSION: A new risk algorithm with higher sensitivity is needed, although the HCM risk-SCD model is still quite useful in identifying patients at a high risk for SCD.

The prognostic impact of inflammation in patients with decompensated acute heart failure, as assessed using the pan-immune inflammation value (PIV).

There is increasing evidence that composite scores based on blood counts, which are reflectors of uncontrolled inflammation in the development and progression of heart failure, can be used as prognostic biomarkers in heart failure patients. The prognostic effects of pan-immune inflammation (PIV) as an independent predictor of in-hospital mortality in patients with acute heart failure (AHF) were evaluated based on this evidence. The data of 640 consecutive patients hospitalized for New York Heart Association (NYHA) class 2-3-4 AHF with reduced ejection fraction were analyzed and 565 patients were included after exclusion. The primary outcome was in hospital all-cause death. Secondary outcomes were defined as the following in-hospital events: Acute kidney injury (AKI), malignant arrhythmias, acute renal failure (ARF) and stroke. The PIV was computed using hemogram parameters such as lymphocytes, neutrophils, monocytes and platelets. Patients were categorized as low or high PIV group according to the median value, which was 382.8. A total of 81 (14.3%) in-hospital deaths, 31 (5.4%) AKI, 34 (6%) malignant arrhythmias, 60 (10.6%) ARF and 11 (2%) strokes were reported. Patients with high PIV had a higher in-hospital mortality rate than patients with low PIV (OR: 1.51, 95% CI, 1.26-1.80, p < 0.001). Incorporating PIV into the full model significantly improved model performance (odds ratio X2, p < 0.001) compared to the baseline model constructed with other inflammatory markers. PIV is a potent predictor of prognosis with better performance than other well-known inflammatory markers for patients with AHF.

Left Ventricular Mass Index Predicts Pacemaker-Induced Cardiomyopathy in Patients with Dual Chamber Permanent Pacemakers Implanted Due to Complete Atrioventricular Block.

Background: Pacing-induced cardiomyopathy (PICM) occurs as a result of high-burden right ventricular (RV) pacing, which usually develops in patients with complete atrioventricular (AV) block. There is a paucity of data on the association between PICM and pre-implantation left ventricular mass index (LVMI). Thus, the purpose of this study was to analyze the influence of LVMI on PICM in patients who had dual chamber permanent pacemakers (PPMs) implanted secondary to complete AV block. Methods: Overall, 577 patients with dual chamber permanent pacemakers (PPMs) were classified into three tertiles according to their pre- implantation LVMI. The average follow-up period was 57 ± 38 months. The baseline characteristics, laboratory and echocardiographic variables were compared between the tertiles. PICM was defined as a ≥ 10% drop in left ventricular ejection fraction (LVEF) from pre-implantation with a resultant LVEF < 50%. PICM occurred in 42 (7.2%) patients. The independent predictors of PICM development, as well as the impact of LVMI on PICM, were investigated. Results: After controlling for confounding baseline variables, the tertile with the greatest LVMI had a 1.8 times higher risk for the development of long-term PICM compared with the tertile with the lowest LVMI, which was accepted as the reference group. A receiver operating characteristic curve analysis revealed that the best LVMI cut- off value for predicting long-term PICM was 109.8 g/m2 with 71% sensitivity and 62% specificity (area under curve: 0.68; 95% confidence interval: 0.60-0.76; p < 0.001). Conclusions: This investigation revealed that pre-implantation LVMI had a prognostic role in predicting PICM in patients with an implanted dual chamber PPM due to complete AV block.

Evaluating systemic immune-inflammation index in patients with implantable cardioverter defibrillator for heart failure with reduced ejection fraction.

BACKGROUND: Pro-inflammatory pathways play an important role in the follow-ups of patients with intracardiac defibrillators (ICDs) for heart failure (HF) reduced with ejection fraction (HFrEF). A newly defined index - the systemic immune-inflammation index (SII)-has recently been reported to have prognostic value in patients with cardiovascular disease. This study's aim is to evaluate the SII value regarding its association with long-term mortality and appropriate ICD therapy during a 10-year follow-up. METHODS: This retrospective study included 1011 patients with ICD for HFrEF. The SII was calculated as the neutrophil-to-lymphocyte ratio × total platelet count in the peripheral blood. The study population was divided into two groups according to the SII's optimal cut-off value to predict long-term mortality. The long-term prognostic impact of SII on these patients was evaluated regarding mortality and appropriate ICD therapy. RESULTS: The patients with a higher SII (≥1119) had significantly higher long-term mortality and appropriate ICD therapy rates. After adjustment for all confounding factors, the long-term mortality rate was 5.1 for a higher SII. (95% CI: 2.9-8.1). The long-term appropriate ICD therapy rate was 2.0 for a higher SII (95% CI: 1.4-3.0). CONCLUSION: SII may be an independent predictive marker for both long-term mortality and appropriate ICD therapy in patients with HFrEF.

Cardiac variables associated with atrial fibrillation occurrence and mortality in octogenarians implanted with dual chamber permanent pacemakers.

BACKGROUND: There is a dearth of data on the predictors of atrial fibrillation (AF) and the association between AF and long-term mortality in octogenarians with dual-chamber permanent pacemakers (PPM). We investigate the occurrence of AF and whether it is associated with overall mortality among octogenarians with dual-chamber PPM implants. METHODS: Three hundred and fifty-four patients with PPM implants were divided into two groups based on their long-term survival status. Baseline characteristics, laboratory variables, and echocardiographic variables were then compared between the groups, and independent predictors of the long-term incidence of AF and mortality were determined. RESULTS: Multivariable Cox regression analysis performed after adjusting for the parameters in univariable analysis revealed that diabetes, urea levels, albumin levels, paced QRS duration, and the frequency of atrial high-rate episodes (AHREs) were independently associated with a long-term risk of AF in octogenarians after having dual chamber PPMs implanted. The left ventricular (LV) ejection fraction, left atrial (LA) anteroposterior diameter, and AHRE + AF (HR 1.498, 95%CI 1.003-2.237, p = 0.048) were independent risk factors for the long-term mortality in octogenarians receiving dual-chamber PPMs implants. CONCLUSION: The occurrence of AF following dual-chamber PPM implantation is a significant prognostic factor in octogenarian patients.

Comparison of mortality prediction scores in elderly patients with ICD for heart failure with reduced ejection fraction.

BACKGROUND: This investigation aimed to examine and compare the predictive value of MADIT-II, FADES, PACE and SHOCKED scores in predicting one-year and long-term all-cause mortality in implantable cardioverter-defibrillator (ICD) implanted patients, 75 years old and older, since there has been an area of uncertainty about the utility and usefulness of these available risk scores in such cases. METHODS: In this observational, retrospective study, 189 ICD implanted geriatric patients were divided into two groups according to the presence of long-term mortality in follow-up. The baseline characteristics and laboratory variables were compared between the groups. MADIT-II, FADES, PACE and SHOCKED scores were calculated at the time of ICD implantation. One-year and long-term predictive values of these scores were compared by a receiver-operating curve (ROC) analysis. RESULTS: A ROC analysis showed that the best cutoff value of the MADIT-II score to predict one-year mortality was ≥ 3 with 87% sensitivity and 74% specificity (AUC 0.83; 95% CI 0.73-0.94; p < 0.001) and that for long-term mortality was ≥ 2 with 83% sensitivity and 43% specificity (AUC 0.68; 95% CI 0.60-0.76; p < 0.001). The predictive value of MADIT-II was superior to FADES, PACE and SHOCKED scores in ICD implanted patients who are 75 years and older. CONCLUSION: MADIT-II score has a significant prognostic value as compared to FADES, PACE and SHOCKED scores for the prediction of one-year and long-term follow-up in geriatric patients with implanted ICDs for heart failure with reduced ejection fraction.

The use of ivabradine in a patient with idiopathic ventricular arrhythmia originating from the left ventricular summit.

Idiopathic ventricular arrhythmias (VA) are common and treatment options include anti-arrhythmic drugs (AAD) or catheter ablation. Patients presenting with idiopathic VA which is originating from the left ventricular summit (LVS) poses a particular challenge as the success for catheter ablation is low and AAD's may not be used long-term due to side effects. Ivabradine is an inhibitor of funny current (If) in cardiac pacemaker cells by blocking hyperpolarization-activated cyclic nucleotide-gated (HCN). In the present case, we reported the use of ivabradine in treatment of idiopathic VA which was originated from LVS and was resistant to multiple AAD's and catheter ablation.

The value of C-reactive protein-to-albumin ratio in predicting long-term mortality among HFrEF patients with implantable cardiac defibrillators.

BACKGROUND: Patients with heart failure with reduced ejection fraction (HFrEF) who received implantable cardiac defibrillator (ICD) still remain at high risk due to pump failure and prevalent comorbid conditions. The primary aim of this research was to evaluate the predictive value of C-reactive protein-to-albumin ratio (CAR) for all-cause mortality among patients with HFrEF despite ICD implantation. MATERIALS AND METHODS: Those who were implanted ICD for HFrEF in our institution between 2009 and 2019 were included. Data were extracted from hospital's database. CAR was calculated as ratio of C-reactive protein (CRP) to serum albumin concentration. Patients were grouped into tertiles in accordance with CAR at the time of the implantation. During follow-up duration of 38 [17-77] months, survival times of tertiles were compared by using Kaplan-Meier survival method. Forward Cox proportional regression model was used for multivariable analysis. RESULTS: Thousand and eleven patients constituted the study population. Ischaemic cardiomyopathy was the primary diagnosis in 92.3%, and ICD was implanted for the primary prevention among 33.9% of patients. Of those, 14.5% died after the discharge. Patients in tertile 3 (T3) had higher risk of mortality (4.2% vs 11.0% vs 28.5%) compared with those in other tertiles. Multivariable analysis revealed that when patients in T1 were considered as the reference, both those in T2 and those in T3 had independently higher risk of all-cause mortality. This finding was consistent in the unadjusted and adjusted multivariable models. CONCLUSION: Among patients with HFrEF and ICD, elevated CAR increased the risk of all-cause mortality at long term.

Prognostic nutritional index as the predictor of long-term mortality among HFrEF patients with ICD.

BACKGROUND: The benefit of implantable cardiac defibrillator (ICD) in patients with heart failure and reduced ejection fraction (HFrEF) could be limited in a particular group of patients. Low prognostic nutritional index (PNI) indicates malnutrition and proinflammatory condition. We sought to investigate the value of PNI in predicting long-term mortality among HFrEF patients with ICD. METHODS: Electronic database was searched for identifying patients with HFrEF who were implanted ICD in our institution between 2009 and 2019. Demographic and clinical characteristics of included patients were recorded. PNI was calculated according to the formula: 10 × serum albumin (g/dL) + 0.005 × total lymphocyte count (per mm3 ). Patients were divided into the quartiles according to PNI values. Differences between the groups were analyzed by the log-rank test. A forward Cox proportional regression model was used for multivariable analysis. RESULTS: One thousand and hundred patients were included to the study. The underlying heart failure etiology was ischemic and nonischemic in 77.3% and 22.7% of patients, respectively. Mortality rate in Q1 (5.1%) was considered as the reference. In the unadjusted model the mortality rate was 9.5% (hazard ratio [HR] 1.76, 95% confidence interval [95% CI] [0.92-3.38]) in Q2, 10.2% (HR 1.88, 95% CI 0.99-3.58) in Q3, and 39.6% (HR 8.12, 95% CI 4.65-14.17) in Q4. The same trend was consistent in the age- and sex-adjusted, comorbidities-adjusted, and covariates-adjusted models. CONCLUSION: Among patients who were implanted with ICD secondary to HFrEF, lower PNI value predicted all-cause mortality during long-term follow-up. This is the first study demonstrating the value of PNI in this population.

Electrocardiographic Ccharacteristics of metastatic cardiac tumors presenting with ST-segment elevation.

INTRODUCTION: ST segment elevation (STE) in the standard 12­lead surface electrocardiography (ECG) is a well-known finding in patients with metastatic cardiac tumors. It is important to identify the specific characteristics of STE among those patients to prevent unnecessary aggressive treatments. In the present study, we aimed to demonstrate the ECG characteristics of patients with metastatic cardiac tumors who has STE. MATERIAL AND METHODS: Medical literature was searched from Pubmed database with key words "metastatic cardiac tumors" or "cardiac tumors" and "ST segment elevation" or "ST elevation". In addition, remaining articles were explored using the references of case reports which were obtained during former screening (snowball procedure). RESULTS: Thirty six of 46 case reports were included and ECG characteristics of each case were evaluated. Convex- shaped STE was observed in all patients and it showed a specific coronary territory in 35 of 36 patients (97.2%). Pathologic Q wave and/or loss of R wave progression were observed in only one patient. T wave inversion following STE was detected in 34 patients (94.4%). STE evolution was absent in 32 of 36 patients while the information regarding STE evolution were not provided in the remaining cases. CONCLUSION: STE due to tumor invasion has certain characteristics which could help clinicians in the differential diagnosis.

Successful Percutaneous Closure of an Aorto-right Ventricular Fistula After Sutureless Aortic Valve Replacement: A Case Report.

Rupture of a sinus of valsalva aneurysm (SVA) and the development of an aorto-right ventricular fistula (ARVF) is a rare condition, associated with high morbidity and mortality rates if left untreated. Opening of the SVA rupture into the right heart chambers may result in various morbidities, such as pulmonary hypertension. We present a case of a patient who developed ARVF following sutureless aortic valve replacement, and was subsequently treated successfully via a percutaneous approach.

Effects of SGLT2 inhibitors on right ventricular function in heart failure patients: Updated meta-analysis of the current literature.

BACKGROUND: There is some discrepancy in current studies concerning the effect of sodium-glucose cotransporter type 2 inhibitors (SGLT2i) on right ventricular (RV) functions in heart failure (HF) patients. Hence, this meta-analysis was focused on determining the impact of SGLT2i on RV functions in such individuals. MATERIAL AND METHODS: Two independent investigators searched PubMed, Google Scholar, and the Cochrane Library for articles of interest. To analyze heterogeneity, Higgins' I2 as well as prediction intervals and Egger's test were used to assess heterogeneity. The Newcastle-Ottawa standard ratings approach was used to assess the quality of observational studies. The ROBINS-I risk of bias algorithm was used to assess bias risks of randomized studies. RESULTS: This meta-analysis evaluated 8 studies in total. Over the follow-up time frame, patients who used SGLT2i had substantially lower systolic pulmonary artery pressure and higher tricuspid annular plane systolic excursion values (mean difference [MD] = -5.23 [-7.81; -2.66] and, MD = 1.47 [1.01; 1.93]; P <0.01, respectively). There was no significant difference in RVS' values between follow-up and baseline (MD = 1.54 [-0.19; 3.26]; P = 0.08). However, as compared to the baseline period, fractional area contraction values were substantially larger at the end of the follow-up (MD = 5.52 [4.23; 6.82]; P <0.01). CONCLUSION: To the best of our knowledge, this is the first meta-analysis assessing the impact of SGLT2i on RV function in HF patients. Our findings suggest that SGLT2i may improve RV performance in HF patients.

Prognostic value of serum albumin in heart failure patients with cardiac resynchronization therapy.

Aim: There is a lack of data about the association between admission serum albumin levels and long-term mortality in heart failure (HF) patients with cardiac resynchronization therapy defibrillators (CRT-D). We aim to investigate this connection in HF patients with CRT-D. Methods: The study population consisted of 477 HF patients with CRT-D. The cohort was divided into three groups according to albumin values, and the relationship between these groups and long-term mortality were evaluated. Results: Long-term all-cause mortality (HR: 3.32, 95% CI: 2.12-6.84), appropriate (HR: 4.44, 95% CI: 2.44-8.06) and inappropriate (HR: 2.95, 95% CI: 1.88-6.02) shocks were higher in the low albumin group. Conclusion: Low albumin levels are associated with the long-term mortality and appropriate shock treatment in HF patients with CRT-D.

Evaluation of Naples prognostic score to predict long-term mortality in patients with pulmonary embolism.

Background: The Naples prognostic score (NPS), which reflects the inflammatory and nutritional status of patients, is often used to determine prognosis in cancer patients. The aim of this study was to determine the long-term prognostic value of the NPS in acute pulmonary embolism (APE) patients. Methods: Two hundred thirty-nine patients diagnosed with APE were divided into two groups according to their NPS, and long-term mortality was compared. Results: The long-term mortality was observed in 38 patients out of 293 patients in the mean follow-up of 24 months. Multivariate analysis showed that NPS as a categorical parameter and NPS as a numeric parameter were independent predictors of long-term mortality. Conclusion: This study highlights that NPS may have the potential to predict long-term mortality in APE patients.
