Background/introduction: Heart failure patients with reduced ejection fraction are at high risk for ventricular arrhythmias and sudden cardiac death. Ivabradine, a specific inhibitor of the If current in the sinoatrial node, provides heart rate reduction in sinus rhythm and angina control in chronic coronary syndromes., Objective: The effect of ivabradine on ventricular arrhythmias in heart failure patients with reduced ejection fraction patients has not been fully elucidated. The aim of this study was to investigate the effect of ivabradine use on life-threatening arrhythmias and long-term mortality in heart failure patients with reduced ejection fraction patients., Methods: In this retrospective study, 1,639 patients with heart failure patients with reduced ejection fraction were included. Patients were divided into two groups: ivabradine users and nonusers. Patients presenting with ventricular tachycardia, the presence of ventricular extrasystole, and ventricular tachycardia in 24-h rhythm monitoring, appropriate implantable cardioverter-defibrillator shocks, and long-term mortality outcomes were evaluated according to ivabradine use., Results: After adjustment for all possible variables, admission with ventricular tachycardia was three times higher in ivabradine nonusers (95% confidence interval 1.5-10.2). The presence of premature ventricular contractions and ventricular tachycardias in 24-h rhythm Holter monitoring was notably higher in ivabradine nonusers. According to the adjusted model for all variables, 4.1 times more appropriate implantable cardioverter-defibrillator shocks were observed in the ivabradine nonusers than the users (95%CI 1.8-9.6). Long-term mortality did not differ between these groups after adjustment for all covariates., Conclusion: The use of ivabradine reduced the appropriate implantable cardioverter-defibrillator discharge in heart failure patients with reduced ejection fraction patients. Ivabradine has potential in the treatment of ventricular arrhythmias in heart failure patients with reduced ejection fraction patients.

Background: This investigation aims to assess the influence of a mobile application and smart devices on cardiopulmonary exercise testing (CPET) over a one-year period in individuals who have high risk for cardiovascular disease., Methods: This is a post-hoc subgroup analysis of Lifestyle Intervention Using Mobile Technology in Patients with High Cardiovascular Risk: A Pragmatic Randomised Clinical Trial (LIGHT). In the intervention plus standard care standard standard care arms, 138 and 103 patients were recruited, respectively. The 1-year VO 2 measurements were adjusted to the baseline VO 2 measurements as the study's endpoint. VO 2 measurements were taken for each subject during the randomisation and final CPET examinations., Results: The intervention plus standard care improved VO 2 measurements by 1.1 (adjusted treatment effect 1.1, 95% confidence interval (CI): 0.8, 1.4, p  < 0.001) compared to standard care following 1-year follow-up., Conclusion: At a 1-year follow-up, the smart device and mobile application technologies increased VO 2 measurements in individuals with high cardiovascular risk compared to conventional treatment alone.

Background and Objectives: The morphology-voltage-P-wave duration (MVP) electrocardiography (ECG) risk score is a newly defined scoring system that has recently been used for atrial fibrillation (AF) prediction. The aim of this study was to evaluate the ability of the MVP ECG risk score to predict AF in patients with an implantable cardioverter defibrillator (ICD) and heart failure with reduced ejection fraction in long-term follow-up., Methods: The study used a single-center, and retrospective design. The study included 328 patients who underwent ICD implantation in our hospital between January 2010 and April 2021, diagnosed with heart failure. The patients were divided into low, intermediate and high-risk categories according to the MVP ECG risk scores. The long-term development of atrial fibrillation was compared among these 3 groups., Results: The low-risk group included 191 patients, the intermediate-risk group 114 patients, and the high-risk group 23 patients. The long-term AF development rate was 12.0% in the low-risk group, 21.9% in the intermediate risk group, and 78.3% in the high-risk group. Patients in the high-risk group were found to have 5.2 times higher rates of long-term AF occurrence compared to low-risk group., Conclusions: The MVP ECG risk score, which is an inexpensive, simple and easily accessible tool, was found to be a significant predictor of the development of AF in the long-term follow-up of patients with an ICD with heart failure with reduced ejection fraction. This risk score may be used to identify patients who require close follow-up for development and management of AF., Competing Interests: The authors have no financial conflicts of interest., (Copyright © 2023.

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/m 2 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., Competing Interests: The authors have no conflict of interest regarding to publishing this article.

Objective: Acute heart failure remains at high risk of mortality despite recent advances in the management and treatment of heart failure. Recently, C-reactive protein to albumin ratio has been shown to predict all-cause mortality in heart failure with reduced ejection fraction. The association between C-reactive protein to albumin ratio and in-hospital mortality in patients with acute heart failure regardless of the left ventricular ejection fraction remains unknown., Methods: In this retrospective, single-center cohort study, we included 374 hospitalized patients with acute decompensated heart failure. We calculated C-reactive protein to albumin ratio and evaluated the relationship between the values and in-hospital mortality., Results: During hospitalization duration of 10 [6-17] days, need for hemodialysis/ultrafiltration, acute ischemic hepatitis, coagulopathy, ventricular tachycardia, invasive mechanical ventilation, and shock were more prevalent in the high C-reactive protein to albumin ratio (< 0.78) group compared to low C-reactive protein to albumin ratio ( ≥ 0.78) group. Mortality was higher in the high C-reactive protein to albumin ratio group in comparison to the low C-reactive protein to albumin ratio group (36.7% vs. 12%; P < 0.001). C-reactive protein to albumin ratio was independently and significantly associated with in-hospital mortality (hazard ratio = 1.69, 95% CI: 1.02-2.82; P = 0.042) by multivariate Cox proportional hazard analysis. In receiver operating characteristic analysis, C-reactive protein to albumin ratio was able to predict in-hospital mortality (area under the curve value for in-hospital mortality was 0.72; P < 0.001)., Conclusion: Admission C-reactive protein to albumin ratio was associated with increased all-cause mortality in hospitalized patients with acute decompensated heart failure.

Treadmill Exercise Test (TET) results and patients' clinical symptoms influence cardiologists' decision to perform Coronary Angiography (CAG) which is an invasive procedure. Since TET has high false positive rates, it can cause an unnecessary invasive CAG. Our primary objective was to develop a machine learning model capable of optimizing TET performance based on electrocardiography (ECG) waves characteristics and signals. TET reports from 294 patients who underwent CAG following high risk TET were collected and categorized into those with critical CAD and others. The signal was converted to time series format. A dataset containing the P, QRS, and T wave times and amplitudes was created. Using this dataset, 5 machine learning algorithms were trained with 5-fold cross validation. All these models were then compared to the performance of cardiologists on V5 signal. The results from 5 machine learning models were clearly superior to the cardiologists' V5 signal performance (P < 0.0001). In addition, the XGBoost model, with an accuracy of 80.92±6.42% and an area under the curve (AUC) of 0.78±0.06, was the most successful model. Machine learning models can produce high-performance diagnoses using the V5 signal markers only as it does not require any clinical markers obtained from TET reports. This can lead to significant contributions to improving clinical prediction in non-invasive methods., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Objective: Acute coronary syndrome patients should be closely followed-up to maintain optimal adherence to medical treatments and to reduce adverse events. Digital health interventions might provide improved outcomes for patient care by providing closer follow- up, compared to standard care. Thus, in this meta-analysis, we aimed to evaluate the effect of digital health interventions on follow-up in acute coronary syndrome patients., Methods: We searched medical databases to obtain all relevant studies comparing digital health interventions with standard care in acute coronary syndrome patients. After reviewing all eligible studies, a meta-analysis was conducted with the remaining 11 randomized controlled studies and 2 non-randomized controlled studies. A modified Jadad scale and Newcastle-Ottawa scale were used to assess the quality of the publications for randomized controlled studies and non-randomized controlled studies, respectively., Results: This meta-analysis consisted of 7657 patients. The all-cause mortality rate was 49% lower in the digital health intervention cases, compared to those who received standard care [relative risk (RR) = 0.51 (0.37; 0.70), P <.01]. There was a significant decrease in systolic blood pressure in the digital health interventions group, compared to the standard care group [mean difference = -5.28 (-9.47; -1.08), P =.01]. The rate of nonadherence to anti-aggregant drugs was 69% lower in the digital health interventions than in the standard care group [RR = 0.31 (0.20; 0.46), P <.01]. Also, nonadherence rates for statin and beta-blockers were lower in the digital health interventions group. The risk of rehospitalization was observed to be 55% less in the digital health interventions patients, compared to the standard care group [RR = 0.45 (0.30; 0.67), P <.01]., Conclusion: Digital health interventions can be effective in follow-up for secondary prevention in acute coronary syndrome patients.

Background: The purpose of this investigation was to examine the association between average 1-year home blood pressure and the change in left ventricular mass index (LVMI) and pro-brain natriuretic peptide (BNP) levels., Methods: This prospective study was a subgroup analysis of lifestyle intervention using mobile technology in patients with high cardiovascular risk: a pragmatic randomized clinical Trial (LIGHT). In total, 242 patients were stratified into tertiles according to their average 1-year home blood pressure., Results: Patients grouped into the tertile 3 (T3) had a lower 1-year mean, SBP and DBP. The T3 group had a 2.1 times higher rate of decrease in pro-BNP and a 1.6 times higher rate of decrease in LVMI compared with T1, compared with the reference group. The area under curve (AUC) value of average 1-year home blood pressure was higher than that of mean SBP or DBP. (AUC, 0.75 vs. AUC, 0.70 vs. AUC, 0.69, respectively). Spearman rank correlation demonstrated that average 1-year home blood pressure had a correlation with Δpro-BNP and ΔLVMI., Conclusion: The present study showed that average 1-year home blood pressure may have a significant association with a decrease in LVMI and pro-BNP. Our study appears to be the first to evaluate the association between average 1-year home blood pressure and the change in LVMI and pro-BNP., (Copyright © 2022 Wolters Kluwer Health, Inc.

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., (© 2022.

Objective: There is an evidence gap regarding the predictive accuracy of the triglyceride-glucose (TyG) index for long-term major adverse cardiovascular events (MACEs) in individuals with high cardiovascular risk. The aim of this investigation was to evaluate the predictive value of the TyG index for long-term MACEs in patients at high cardiovascular risk., Methods: In total, 483 patients with high cardiovascular risk were included in this analysis. The study population was separated into 2 groups depending on the occurrence of long-term MACEs. The independent predictors of long-term MACEs in patients with high cardiovascular risk were investigated. The long-term prognostic value of the TyG index in these patients was evaluated in terms of MACEs., Results: Age, male sex, diabetes mellitus, and the TyG index were demonstrated to be independent predictors of long-term MACE occurrence in patients with high cardiovascular risk. The TyG index was independently related to long-term MACEs in patients with high cardiovascular risk (hazard ratio, 1.003; 95% confidence interval [CI], 1.001-1.006; p =0.011). The receiver operating characteristic curve revealed that the optimum value of the TyG index to predict long-term MACEs in the overall study cohort was >9.68, with 65% sensitivity and 63% specificity (area under the curve, 0.71; 95% CI, 0.65-0.77; p <0.001)., Conclusion: The TyG index was demonstrated to be an independent predictor of long-term MACE occurrence in patients with high cardiovascular risk who had not been previously diagnosed with cardiovascular disease., Competing Interests: Conflict of Interest: The authors have no conflicts of interest to declare., (Copyright © 2022 The Korean Society of Lipid and Atherosclerosis.)

Background: This investigation aims to examine the prognostic utility of albumin concentrations for long-term all-cause mortality in patients undergoing permanent pacemaker implantation. Methods: A total of 1798 patients who received permanent pacemaker implantation were divided into quartiles according to serum albumin concentrations. The significance of albumin in predicting long-term mortality was compared in these quartiles. Results: There was a higher rate of long-term mortality in the Q4 group compared with the Q1-3 groups (49.9 vs 15.8%). The risk of long-term mortality in the Q4 group was 3.6-times higher compared with the Q1-3 groups after adjustment for confounders. Conclusion: Serum albumin level at the time of device implantation has great value when assessing long-term mortality in patients with permanent pacemakers.

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., Competing Interests: Declaration of Competing Interest None., (Copyright © 2022 Elsevier Inc.

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., (© 2021.

Implantable cardioverter defibrillators (ICD) are recommended in heart failure with reduced ejection fraction (HFrEF) patients to reduce arrhythmic deaths. This study aimed to identify risk factors associated with mortality within one-year following the ICD. The data from our hospital's electronic database system was extracted for patients who were implanted ICD secondary to HFrEF between 2009 and 2019. Overall, 1107 patients were included in the present analysis. Mortality rate at one-year following the device implantation was 4.7%. In multivariate analysis; age, atrial fibrillation, New York Heart Association classification >2, blood urea nitrogen, pro-brain natriuretic peptide and albumin independently predicted one year mortality., Competing Interests: Declaration of competing interest All authors declare that they do not have conflict of interest., (Copyright © 2022 Cardiological Society of India.

Fighting with the infection is one of the most challenging and costly burdens of the healthcare system. Several types of antibiotics and antibacterial agents have been designed and used in combating this dilemma. Nevertheless, the overuse of drugs and the difficulties of proper delivery have led to the development of drug-resistance in many species of bacteria which has reduced the efficacy of antibiotics. Furthermore, localized delivery of these drugs can be more effective in eliminating biomaterial surface-associated infection compared to systemic administration. This type of infection occurs mostly by the formation of a bacterial biofilm layer on the surface of the implantable biomaterial which is the interface between the biomaterial and the tissue. Sharkskin topography is known for its antibacterial properties due to its unique pattern. Herein, antibacterial properties and drug release potentials of sharkskin mimicked chitosan membranes are investigated with the aim of studying the impact of this topography in reducing bacterial biofilm formation on drug-loaded polymeric membranes. Ampicillin sodium salt and caffeic acid phenethyl ester (CAPE) loaded chitosan (CH) membranes were fabricated. Gram-positive Staphylococcus aureus bacteria strain is used in antibacterial experiments, and human dermal fibroblast (HDFa) and keratinocyte (HaCaT) cells were used as model cell lines in cytocompatibility tests. Drug release, bacterial biofilm growth, and swelling ratio test results show the superiority of sharkskin topography in controlling the rate of drug release as well as considerably reducing bacterial biofilm formation. Furthermore, it was established that 2.5 mg mL -1 Amp content along with 500 μM CAPE yield in maximum antibacterial effect while not having cytotoxic effects on mammalian cells. Fabricated sharkskin mimicked drug-loaded membrane, which utilizes the combination of antibacterial compounds and antibacterial surface topography, also acts as an effective carrier for high concentrations of drugs., Competing Interests: Declaration of competing interest The authors declare no known competing financial interests or personal relationships that could potentially influence the results and outcomes reported in this paper., (Copyright © 2021 Elsevier B.V.

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., (© 2022 Wiley Periodicals LLC.)

A 30-year-old lady was admitted to the hospital with progressive exertional dyspnoea and bradycardia. A complete atrioventricular block was diagnosed using 12‑lead electrocardiography and a transthoracic echocardiography revealed a severely impaired left ventricular systolic dysfunction with an ejection fraction of 20%. Following hospitalization, her coronary angiography was normal, so a whole exome sequencing was conducted. The novel Lamin A/C Gene missense mutation c.263C > A,p.Ala88Asp in exon 3 was identified. A CRT-D was implanted due to the high risk of life-threatening ventricular arrhythmias and low potential for left ventricular reverse remodelling. The patient is undergoing follow-ups at the outpatient clinic, showing a 25% improvement in left ventricular ejection fraction during the last visit., Competing Interests: Declaration of Competing Interest None declared., (Copyright © 2021 Elsevier Inc.

Introduction: In the present study, we aimed to evaluate compliance to lipid lowering guidelines regarding statin prescription on discharge and statin adherence rates during a follow-up period of one year in patients hospitalised with a diagnosis of acute coronary syndrome (ACS)., Methods: In-hospital records of 3506 ACS patients, of which 771 had experienced an ST-elevation myocardial infarction (STEMI) and 2735 had experienced a non-STEMI, were collected. We calculated medication possession ratios (MPRs) for each subject. We designated patients with ≥9 statin refills/year (MPR ≥ 0.75) as the statin-adherent group and patients with <9 statin refills/year (MPR < 0.75) as the statin-non-adherent group., Results: During a 12-month follow-up period, 234 patients in the STEMI group (30.3%) and 391 patients in the non-STEMI group (14.3%) had 12 refills of statin. Thus, only 17.8% of the total study population had complete adherence to statin therapy with an MPR of 1. When patients with ≥9 statin prescriptions were categorised as the statin-adherent group, only 1575 patients (44.9%) were found to be adherent to statin treatment. In multivariate analysis, patients with a non-STEMI diagnosis and high intensity statin treatment had higher rates of non-adherence (OR:1.685, 95%CI:1.412-2.012, p  < .01 and OR:1.344, 95% CI: 1.147-1.574, p  < .01, respectively). Patients with prior statin treatment had lower rates of non-adherence(OR:0.437, 95%CI: 0.346-0.553, p  < .01)., Conclusion: The present study shows that compliance with guidelines regarding statin initiation during hospitalisation and statin adherence rates during a one-year follow-up period are low for patients treated for ACS. Considering the overwhelming clinical benefits of high-intensity statins in patients with ACS, every effort should be made to increase the rate of optimal use of statins in secondary prevention.

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., (© 2021 Stichting European Society for Clinical Investigation Journal Foundation.

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 mm 3 ). 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., (© 2021 Wiley Periodicals LLC.)

Background and Aims: Mobile technology-based solutions present promising effects against cardiovascular diseases. Long-term follow-up in mobile phone-based interventions has not yet been elucidated as a primary prevention technique for cardiovascular diseases. The objective of the present trial is to evaluate the effectiveness of lifestyle intervention on the change in the atherosclerotic cardiovascular disease (ASCVD) risk score in a 1-year follow-up using smart phone technology in patients with high cardiovascular risk., Methods: This prospective, randomised, single-centre clinical investigation enrolled 242 and 241 patients to the intervention plus usual care and usual care arms, respectively. The primary outcome of this study was the 1-year ASCVD risk score adjusted to baseline ASCVD risk score. ASCVD risk scores were calculated for every study participant at the randomisation and final stages., Results: After a 1-year follow-up, the intervention plus usual care reduced the ASCVD score by 2.7% (adjusted treatment effect -2.7, 95% confidence interval (CI): -2.2,-3.3, p<0.0001). An improvement was observed in favour of the intervention plus usual care arm in the majority of the pre-specified secondary endpoints. The high sensitive troponin and high sensitive C-reactive protein levels at 1 year were similar between the two arms. The treatment effect was homogenous for diabetes mellitus, gender, systolic blood pressure, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides and body mass index; however, heterogeneity in the treatment effect was observed for age., Conclusions: The lifestyle intervention using smart phone technology compared to usual care alone in patients with high cardiovascular risk reduced the ASCVD score at 1-year follow-up., (Copyright © 2020 Elsevier B.V.

Background: This investigation aims to evaluate the effect of a mobile application and smart devices on frequency and time domains of heart rate variability (HRV) in diabetic patients in 1-year follow-up., Methods: This is post-hoc analysis of a diabetic subgroup of "Lifestyle Intervention usinG mobile technology in patients with high cardiovascular risk: a pragmatic randomized clinical Trial" (LIGHT). One hundred and nine and 118 patients were enrolled in two arms: the intervention plus usual care and the usual care arm. The study outcome was the 1-year HRV parameters adjusted to the baseline HRV parameters. HRV measures were recorded for every patient at the randomization and final visits with 24-hour Holter monitoring., Results: There was an improvement in the standard deviation of normal to normal (SDNN) R-R intervals 24-hour by 4.8 (adjusted treatment effect 4.8, 95% confidence interval [CI], 0.1-9.5; P = 0.044) in the intervention-plus-usual-care arm compared to usual care after a 1-year follow-up. The improvement was also experienced in other HRV time domains including standard deviation of the mean R-R intervals calculated over a 5-minute period, SDNN, square root of the mean squared difference of successive R-R intervals, and the percentage of the differences between adjacent normal R-R intervals exceeding 50 milliseconds. A significant enhancement was also detected in HRV frequency domains of total power low frequency and high frequency in the intervention plus usual care compared to usual care after a 1-year follow-up., Conclusions: The mobile application and smart device technology compared to usual care alone improved HRV parameters in diabetic patients at 1-year follow-up.

Electrocardiography (ECG) remains an irreplaceable tool in the management of the patients with myocardial infarction, with evaluation of the QRS and ST segment being the present major focus. Several ECG parameters have already been proposed to have prognostic value with regard to both in-hospital and long-term follow-up of patients. In this review, we discuss various ECG parameters other than ST segment changes, particularly with regard to their in-hospital prognostic importance. Our review not only evaluates the prognostic segments and parts of ECG, but also highlights the need for an integrative approach in big data to re-assess the parameters reported to predict in-hospital prognosis. The evolving importance of artificial intelligence in evaluation of ECG, particularly with regard to predicting prognosis, and the potential integration with other patient characteristics to predict prognosis, are discussed., (Copyright © 2020 Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) and the Cardiac Society of Australia and New Zealand (CSANZ).

INTRODUCTION Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a newly described virus responsible for the outbreak of the coronavirus disease 2019 (Covid-19), named by the World Health Organization (WHO) in February/2020. Patients with Covid-19 have an incidence of acute respiratory distress syndrome (ARDS) of 15.9-29% and sepsis is observed in all deceased patients. Moreover, disseminated intravascular coagulation (DIC) is one of the major underlying causes of death among these patients. In patients with DIC, there is a decrease in fibrinogen and an increase in D-dimer levels. Some studies have shown that fibrinogen and one of its end products, D-dimer, might have a predictive value for mortality in patients with non-Covid sepsis secondary to complications of DIC. Therefore, anticoagulation, considering its mortality benefits in cases of non-Covid sepsis, may also have an important role in the treatment of Covid-19. METHODS We reviewed the literature of all studies published by April 2020 on patients infected with Covid-19. Our review was limited to D-dimer and fibrinogen changes and anticoagulation recommendations. RESULTS Anticoagulation therapy can be started following the DIC diagnosis in Covid-19 patients despite the bleeding risks. In addition, the current evidence suggests a routine use of anticoagulation, particularly in patients with higher D-dimer levels (> 3.0 μg/mL). CONCLUSION Covid-19 is a systemic, hypercoagulable disease requiring more studies concerning treatment. Aanticoagulation is still an issue to be studied, but D-dimer rise and disease severity are the indicative factors to start treatment as soon as possible.

In December 2019, in the city of Wuhan, in the Hubei province of China, treatment-resistant cases of pneumonia emerged and spread rapidly for reasons unknown. A new strain of coronavirus (severe acute respiratory syndrome coronavirus-2 [SARS-CoV-2]) was identified and caused the first pandemic of the 21st century. The virus was officially detected in our country on March 11, 2020, and the number of cases increased rapidly; the virus was isolated in 670 patients within 10 days. The rapid increase in the number of patients has required our physicians to learn to protect both the public and themselves when treating patients with this highly infectious disease. The group most affected by the outbreak and with the highest mortality rate is elderly patients with known cardiovascular disease. Therefore, it is necessary for cardiology specialists to take an active role in combating the epidemic. The aim of this article is to make a brief assessment of current information regarding the management of cardiovascular patients affected by COVID-19 and to provide practical suggestions to cardiology specialists about problems and questions they have frequently encountered.

Objective: Acute kidney injury (AKI) is a reflection of both renal and cardiac reserve in patients with ST-segment elevation myocardial infarction (STEMI), but there is a lack of evidence related to the effect of AKI on long-term mortality in patients with STEMI. This study was an investigation of the prognostic value of AKI for long-term mortality in patients with STEMI complicated by cardiogenic shock (CS) and primary percutaneous coronary intervention (PPCI)., Methods: This retrospective analysis evaluated the long-term prognostic impact of AKI on 492 patients with STEMI complicated by CS who were treated with PPCI. AKI was defined as ≥0.3mg/dL increase in serum creatinine within 48 hours or a ≥50% increase in serum creatinine in 7 days, or a reduction in urine output (documented oliguria of less than 0.5mL/kg per hour >6 hours. Patients were grouped according to the incidence of AKI and long-term mortality was compared. Cox regression analysis was used to determine independent prognostic factors of long-term mortality., Results: In Cox regression analysis, the age- and sex- adjusted hazard ratios (HRs) were higher for all-cause mortality in patients with AKI. [HR: 4.556; 95% confidence interval: (CI) 2.370-8.759]. After adjustment for confounding variables, the relative risk was greater for patients with AKI in comparison with patients without AKI (HR: 2.207; 95% CI: 1.150-4.739). Age (HR: 1.060, 95% CI: 1.027-1.094; p<0.001), left ventricular ejection fraction (HR: 0.952, 95% CI: 0.916-0.989; p=0.012), blood urea nitrogen level (HR: 1.019, 95% CI: 1.005-1.034; p=0.010), and AKI (HR: 2.244, 95% CI: 1.077-4.676; p=0.031) were found to be independent factors to determine long-term mortality., Conclusion: The results of this study demonstrated that AKI was an independent prognostic factor for long-term mortality among patients with STEMI complicated by CS and treated with PPCI.

Objective: In this study, we aimed to determine the predictive value of the CHA2DS2VASc score for acute stent thrombosis in patients with an ST elevation myocardial infarction treated with a primary percutaneous coronary intervention (pPCI)., Methods: This was a retrospective study conducted among 3,460 consecutive patients with STEMI who underwent a pPCI. The stent thrombosis was considered a definite or confirmed event in the presence of symptoms suggestive of acute coronary syndrome and angiographic confirmation of stent thrombosis based on the diagnostic guidelines of the Academic Research Consortium. The stent thrombosis was classified as acute if it developed within 24 h., Results: The mean CHA2DS2VASc score was 3.29 ± 1.73 in the stent thrombosis group, whereas it was 2.06 ± 1.14 in the control group (p < 0.001). In multivariable logistic regression analysis, CHA2DS2VASc scores ≥ 4 were independently associat ed with acute stent thrombosis (OR = 1.64; 95% CI 1.54-1.71, p < 0.001). In a receiver operating characteristic curve ana-lysis, the best cut-off value for the CHA2DS2VASc score was ≥4, with 60% sensitivity and 73% specificity. Of note, pa tients with a CHA2DS2VASc score of 4 had a 4.3 times higher risk of acute stent thrombosis compared to those with a CHA2DS2VASc score of 1., Conclusions: The CHA2DS2VASc score may be a significant independent predictor of acute stent thrombosis in patients with STEMI treated with a pPCI. Therefore, the CHA2DS2VASc score may be used to assess the risk of acute stent thrombosis in patients with STEMI following a pPCI., (© 2018 The Author(s) Published by S. Karger AG, Basel.)

Objective: The aim of the present study was to evaluate in-hospital and long-term outcomes of ST-segment elevation myocardial infarction (STEMI) survivors who experienced out-of-hospital cardiac arrest (OHCA) and underwent primary percutaneous coronary intervention (PCI) at a high-volume center within the STEMI network., Methods: The records of 2681 consecutive STEMI patients who underwent primary PCI between January 2009 and December 2014 at a single center in the STEMI network were retrospectively analyzed. Patients with STEMI complicated by OHCA were compared with a reference group of STEMI patients who did not experience OHCA., Results: Compared with STEMI survivors without OHCA (n=2587, 96.5%), the frequency of anterior myocardial infarction, duration of hospitalization, rate of in-hospital major adverse cardiovascular and cerebrovascular events, and the incidence of ischemic cerebrovascular disease and major bleeding during in-hospital follow-up were significantly greater in those with OHCA (n=94, 3.5%). The distribution of age and gender was similar between the 2 groups. The primary PCI success rate was high and was similar in both groups. In-hospital mortality was significantly higher (18.1% vs. 1.5%; p<0.001) and survival at the 12th and 60th months was lower (74.5% vs. 96.5%; p<0.001 and 71.3% vs. 93.7%; p<0.001) in STEMI survivors with OHCA. OHCA was an independent predictor for in-hospital mortality (Odds ratio [OR]: 3.413; 95% confidence interval [CI]: 1.534-7.597; p=0.003) and all-cause mortality at 60 months (OR: 3.285; 95% CI: 2.020-5.340; p<0.001)., Conclusion: Mortality was high in patients with STEMI complicated by OHCA, even though PCI was performed with the same success rate seen in patients without OHCA.

Background: It may sometimes be difficult to differentiate subtle ST-segment elevation (STE) due to anterior myocardial infarction (MI) from benign variant (BV) STE. Recently, two related formulas were proposed for this purpose. However, they have never been tested in an external population., Materials and Methods: Consecutive patients from May 2017 to January 2018, who were admitted with the diagnosis of acute anterior STEMI, were enrolled. Electrocardiograms were systematically reviewed and only subtle ones were included. First 200 consecutive patients with noncardiac chest pain were also enrolled as a control group. Relevant electrocardiographic parameters were measured., Results: A total of 379 anterior MI and 200 BV-STE cases were enrolled during study period. A total of 241 patients in STEMI group were excluded for not matching subtleness criteria, four patients in control group were also excluded because of prior left-anterior descending artery intervention. The three-variable formula, with recommended cut-point of 23.5, had a sensitivity, specificity, and diagnostic accuracy of 73.9%, 86.7%, and 81.4%, respectively. The four-variable formula, with the published cut-point of 18.2, had a sensitivity, specificity, and diagnostic accuracy of 83.3%, 87.7%, and 85.9%, respectively., Conclusion: Three- and four-variable formulas with recommended cutoffs have a reasonable sensitivity, specificity, and diagnostic accuracy in differentiating subtle STEMI with BV-STE. Although both perform well, the four-variable formula has a higher sensitivity, specificity, and diagnostic accuracy and should be preferred., (© 2018 Wiley Periodicals, Inc.)

Introduction: Previous studies demonstrated that interatrial block (IAB) is associated with atrial fibrillation (AF) in different clinical scenarios. The aim of our study was to determine whether IAB could predict silent ischemic brain lesions (sIBL), detected by magnetic resonance imaging (MRI)., Methods: Patients presented to a neurology clinic with transient ischemic attack (TIA) symptoms and underwent brain MRI were included to the study. sIBL were defined as lesions without corresponding clinical symptoms regarding lesion localization evaluated by two neurologists. A 12-lead surface ECG was obtained from each patient. IAB was defined as P-wave duration > 120 ms with (advanced IAB) or without (partial IAB) biphasic morphology in the inferior leads., Results: sIBL was detected in 61 (49.6%) patients. Patients with sIBL were older (P<0.001), had more left ventricular hypertrophy (LVH) (P=0.02) and higher CHA2DS2-VASc score compared to those without (P<0.001). P-wave duration was significantly longer in patients with sIBL (124 [110.5 - 129] msvs 107 [102 - 116.3] ms) (P<0.001). IAB was diagnosed in 36 patients (59%) with sIBL (+) and in 11 patients (18%) with sIBL (-); p<0.001. Multivariate logistic regression analysis identified age [Odds ratio (OR), 1.061; 95% confidence interval (CI), 1.012 - 1.113; p=0.014], CHA2DS2-VASc score (OR, 1.758; 95% CI, 1.045 - 2.956; p=0.034), LVH (OR, 3.062; 95% CI, 1.161 - 8.076; p=0.024) and IAB (including both partial and advanced) (OR, 5.959; 95% CI, 2.269 - 15.653; p<0.001) as independent predictors of sIBL., Conclusion: IAB is a strong predictor of sIBL and can be easily diagnosed by performing surface 12-lead ECG.

Introduction: Interatrial block (IAB) is strongly associated with recurrence of atrial fibrillation (AF) in different clinical scenarios. Atrial fibrosis is considered the responsible mechanism underlying the pathogenesis of IAB. The aim of this study was to investigate whether IAB predicted AF at 12 months follow-up in a population of patients with ST segment elevation myocardial infarction (STEMI)., Hypothesis: We aimed to investigate whether IAB predicted AF at 12 months follow up in a population of patients with STEMI., Methods: Prospective, single center, observational study of patients presenting with ST-segment elevation myocardial infarction (STEMI) and referred to primary percutaneous coronary intervention (P-PCI). Surface electrocardiograms (ECG) were recorded on admission and at 6th hour post P-PCI. Patients were screened for the occurrence of AF at a 12-months visit., Results: A total of 198 patients were included between September 2015 and September 2016. IAB (partial and advanced) was detected in 102 (51.5%) patients on admission. Remodeling of the P-wave and subsequent normalization reduced the prevalence of IAB to 47 (23.7%) patients at 6th hour. AF was detected in 17.7% of study patients at 12 months. Partial IAB (p-IAB) on admission (OR 5.10; 95% CI, 1.46-17.8; P = 0.011) and on 6th hour (OR 4.15; 95% CI, 1.29-13.4; P = 0.017), presence of a lesion in more than one coronary artery (OR 3.29; 95% CI, 1.32-8.16; P = 0.010) found to be independent predictors of AF at 12 months., Conclusion: IAB is common in patients with STEMI and along with the presence of diffuse coronary artery disease is associated with new onset of AF., (© 2018 Wiley Periodicals, Inc.)

Objective: The present study is an investigation of the association between high on-treatment platelet reactivity to clopidogrel (HTPRC) and hepatosteatosis in patients who had elective stent implantation due to coronary artery disease., Methods: A total of 190 consecutive patients who underwent an elective coronary stent implantation due to coronary artery disease were prospectively enrolled in the study. Eligible patients were given a 300 mg loading dose of clopidogrel before percutaneous coronary intervention. All of the patients underwent an ultrasound assessment for fatty liver. The patients were divided into 2 groups according to the detection of HTPRC: patients with HTPRC and patients without HTPRC., Results: HTPRC was present in 54.2% (103 of 190 patients) of the total study population. The age and body mass index data were similar between the 2 groups. In all, 111 (58.6%) patients had hepatosteatosis. The HTPRC ratio was statistically higher in female patients (p=0.032). Hepatosteatosis was significantly greater in patients with HTPRC (p<0.001); 84 (81.6%) patients with HTPRC had hepatosteatosis (p=0.001). There was also a statistically significant association between the hepatosteatosis grade and HTPRC (p<0.001). The percentage of HTPRC was greater in patients with ≥grade 2 hepatosteatosis than grade 1 (p<0.001). Logistic regression analysis indicated that hepatosteatosis (odds ratio: 9.403, 95% confidence interval: 4.519-19.566; p<0.001), fasting blood glucose, and hypertension were independent predictors of HTPRC., Conclusion: To the best of our knowledge, this is the first study to demonstrate a relationship between hepatosteatosis and HTPRC.

Background: Electrical phenomenon and remote myocardial ischemia are the main factors of ST segment depression in inferior leads in acute anterior myocardial infarction (AAMI). We investigated the prognostic value of the sum of ST segment depression amplitudes in inferior leads in patients with first AAMI treated with primary percutaneous coronary intervention. (PPCI)., Methods: In this prospective analysis, we evaluated the in-hospital prognostic impact of the sum of ST segment depression in inferior leads on 206 patients with first AAMI. Patients were stratified by tertiles of the sum of admission ST segment depression in inferior leads. Clinical outcomes were compared between those tertiles., Results: Univariate analysis revealed higher rate of in-hospital death for patients with ST segment depression in inferior leads in tertile 3, as compared to patients in tertile 1 (OR 9.8, 95% CI 1.5-78.2, p<0.001). After adjustment for baseline variables, ST segment depression in inferior leads in tertile 3 was associated with 5.7-fold hazard of in-hospital death (OR: 5.7, 95% CI 1.2-35.1, p<0.001). Spearman rank correlation test revealed correlation between the sum of ST segment depression amplitude in inferior leads and the sum of ST segment elevation amplitude in V1-6, L1 and aVL. Multivessel disease and additional RCA stenosis were also detected more often in tertile 3., Conclusion: The sum of ST segment depression amplitude in inferior leads of admission ECG in patients with first AAMI treated with PPCI provide an independent prognostic marker of in-hospital outcomes. Our data suggest the sum of ST segment depression amplitude to be a simple, feasible and clinically applicable tool for rapid risk stratification in patients with first AAMI., (Copyright © 2017 Elsevier Inc.

Background: The predictive significance of ST-segment elevation (STE) in lead V 4 R in patients with anterior ST-segment elevation myocardial infarction (STEMI) has not been well-understood. In this study, we evaluated the prognostic value of early and late STE in lead V 4 R in patients with anterior STEMI., Methods: A total 451 patients with anterior STEMI who treated with primary percutaneous coronary intervention (PPCI) were prospectively enrolled in this study. All patients were classified according to presence of STE (>1 mm) in lead V 4 R at admission and/or 60 min after PPCI. Based on this classification, all patients were divided into three subgroups as no V 4 R STE (Group 1), early but not late V 4 R STE (Group 2) and late V 4 R STE (Group 3)., Results: In-hospital mortality had higher rates at group 2 and 3 and that had 2.1 and 4.1-times higher mortality than group 1. Late V 4 R STE remained as an independent risk factor for cardiogenic shock (odds ratio [OR] 2.6; 95% confidence interval [CI] 1.9-4.3; p < .001) and in-hospital mortality (OR 2.3; 95% CI 1.8-4.1; p < .001). The 12-month overall survival for group 1, 2, and 3 were 91.1%, 82.4%, and 71.4% respectively. However, the long-term mortality also had the higher rate at group 3; late V 4 R STE did not remain as an independent risk factor for long-term mortality (OR 1.5; 95% CI 0.8-4.1; p: .159)., Conclusion: Late V 4 R STE in patients with anterior STEMI is strongly associated with poor prognosis. The record of late V 4 R in patients with anterior STEMI has an important prognostic value., (© 2017 Wiley Periodicals, Inc.)

Background: Acute transmural ischemia due to left anterior descending artery (LAD) occlusion changes precordial R and Q wave durations owing to depressed intramyocardial activation. We investigated the prognostic value of sum of precordial Q wave duration/sum of precordial R wave duration ratio (Q/R) in patients with first acute anterior myocardial infarction (AAMI) treated with primary percutaneous coronary intervention (PPCI)., Methods: In this prospective analysis, we evaluated the no-reflow predictive value of Q/R on 403 patients with first AAMI. Patients were divided into two as no-reflow group (n=32) and control (n=371) group according to post-PPCI flow status., Results: The patients in the no-reflow group had significantly higher Q/R on admission electrocardiography (ECG) compared to patients in the control group (p<0.001). When admission ECG parameters were compared according to no-reflow prediction, Q/R was stronger than other well-accepted parameters. The best cut-off value of the Q/R to predict no-reflow was 1.08 with 76% sensitivity and 73% specificity (AUC: 0.78; 95% CI: 0.72-0.83; p<0.001)., Conclusion: In patients with first AAMI treated with PPCI, Q/R in admission ECG may have a role as an independent predictive marker of no-reflow., (Copyright © 2017 Elsevier Inc.

Background: We investigated the prognostic value of precordial total Q wave amplitude/precordial total R wave amplitude ratio (Q/R) in patients with first acute anterior MI treated with primary percutaneous coronary intervention (PPCI)., Methods: We evaluated the in-hospital prognostic impact of Q/R on 354 patients with first acute anterior MI. Patients were stratified by tertiles of admission Q/R, clinical outcomes were compared between those groups., Results: In-hospital univariate analysis revealed notably higher rates of in-hospital death for patients in tertile 3, as compared to patients in tertile 1 (OR 9.7, 95% CI 2.8-33.5, p., Conclusion: Q/R in admission ECG in patients with first acute anterior MI provide an independent prognostic marker of in-hospital outcomes., (Copyright © 2017 Elsevier Inc.

Although the long-term clinical benefit of adjunctive thrombus aspiration (TA) during primary percutaneous coronary intervention (PPCI) remains controversial, the impact of TA in patients with large thrombus has not been evaluated. The aim of the present study was to investigate the effect of adjunctive TA during PPCI on clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) and a large thrombus. We assessed the effect of adjunctive TA on in-hospital and 3-year clinical outcomes in 627 patients with STEMI and a large thrombus in the native coronary artery. The cumulative 3-year incidence of all-cause death was not significantly different between the 2 groups (91.5% vs 89.0%, log-rank test p = 0.347). After adjusting for confounders, the risk of all-cause death in the TA group was not significantly lower than that in the non-TA group (hazard ratio 1.11, 95% confidence interval 0.60 to 3.54, p = 0.674). The adjusted risks of target lesion revascularization, nonfatal acute myocardial infarction, and stent thrombosis were also not significantly different between the 2 groups. In conclusion, adjunctive TA during PPCI was not associated with better in-hospital and 3-year all-cause deaths in patients with STEMI and a large coronary artery thrombus., (Copyright © 2017 Elsevier Inc.
