Diabetes Primes Neutrophils for Neutrophil Extracellular Trap Formation through Trained Immunity.

Neutrophils are primed for neutrophil extracellular trap (NET) formation during diabetes, and excessive NET formation from primed neutrophils compromises wound healing in patients with diabetes. Here, we demonstrate that trained immunity mediates diabetes-induced NET priming in neutrophils. Under diabetic conditions, neutrophils exhibit robust metabolic reprogramming comprising enhanced glycolysis via the pentose phosphate pathway and fatty acid oxidation, which result in the accumulation of acetyl-coenzyme A. Adenosine 5'-triphosphate-citrate lyase-mediated accumulation of acetyl-coenzyme A and histone acetyltransferases further induce the acetylation of lysine residues on histone 3 (AcH3K9, AcH3K14, and AcH3K27) and histone 4 (AcH4K8). The pharmacological inhibition of adenosine 5'-triphosphate-citrate lyase and histone acetyltransferases completely inhibited high-glucose-induced NET priming. The trained immunity of neutrophils was further confirmed in neutrophils isolated from patients with diabetes. Our findings suggest that trained immunity mediates functional changes in neutrophils in diabetic environments, and targeting neutrophil-trained immunity may be a potential therapeutic target for controlling inflammatory complications of diabetes.

Clinical impact of capsulectomy during cardiac implantable electronic device generator replacement: a prospective randomized trial.

BACKGROUND: The avascular capsule around the generator of the cardiac implantable electronic device (CIED) could be susceptible to bacterial colonization and source of infection. Capsulectomy during CIED generator replacement may be beneficial in preventing device infection, but there is a lack of evidence. METHODS: This prospective randomized trial, conducted from December 2013 to December 2019, included 195 patients divided equally into two groups. In the intervention group (n = 97), capsule removal was performed on the floor of the pocket, while it was not performed in the control group (n = 98). In both groups, swab culture was performed in the pocket. The primary outcome was the occurrence of device infection requiring pocket revision. RESULTS: A total of 195 patients were included (mean age 70.2 ± 13.6 years, 55.4% women), with an average follow-up period of 54.3 ± 28.9 months. Among 182 patients undergoing microbiological cultures of pockets, 19 (10.4%) were confirmed positive, and Staphylococcus species were identified most frequently. The primary outcome occurred in 4 (2.1%), and there was no significant difference between the two groups (3.1% vs. 1.0%, p = 0.606). Hematoma has occurred in 10 patients (3.1% vs. 7.1%, p = 0.338), one of them required wound revision. In multivariable analysis, the occurrence of hematoma was the only independent risk factor associated with device infection (HR 13.6, 95% CI 1.02-181.15, p = 0.048). CONCLUSIONS: In this long-term prospective study, capsulectomy during the replacement of the generator did not reduce the incidence of device infection. There was no association between bacterial colonization in the capsule around the generator and CIED infection.

Congruency and its related factors between patients' fall risk perception and nurses' fall risk assessment in acute care hospitals.

INTRODUCTION: Inpatients need to recognize their fall risk accurately and objectively. Nurses need to assess how patients perceive their fall risk and identify the factors that influence patients' fall risk perception. PURPOSE: This study aims to explore the congruency between nurses' fall risk assessment and patients' perception of fall risk and identify factors related to the non-congruency of fall risk. DESIGNS: A descriptive and cross-sectional design was used. The study enrolled 386 patients who were admitted to an acute care hospital. Six nurses assessed the participants' fall risk. Congruency was classified using the Morse Fall Scale for nurses and the Fall Risk Perception Questionnaire for patients. FINDINGS: The nurses' fall risk assessments and patients' fall risk perceptions were congruent in 57% of the participants. Underestimation of the patient's risk of falling was associated with gender (women), long hospitalization period, department (orthopedics), low fall efficacy, and history of falls before hospitalization. Overestimation of fall risk was associated with age group, gender (men), department, and a high health literacy score. In the multiple logistic regression, the factors related to the underestimation of fall risk were hospitalization period and department, and the factors related to the overestimation of fall risk were health literacy and department. CONCLUSIONS: Nurses should consider the patient's perception of fall risk and incorporate it into fall prevention interventions. CLINICAL RELEVANCE: Nurses need to evaluate whether patients perceive the risk of falling consistently. For patients who underestimate or overestimate their fall risk, it may be helpful to consider clinical and fall-related characteristics together when evaluating their perception of fall risk.

Prognostic Implication of Platelet Reactivity According to Left Ventricular Systolic Dysfunction Status in Patients Treated With Drug-Eluting Stent Implantation: Analysis of the PTRG-DES Consortium.

BACKGROUND: Coronary artery disease patients undergoing percutaneous coronary intervention (PCI) often exhibit reduced left ventricular ejection fraction (LVEF). However, the impact of LV dysfunction status in conjunction with platelet reactivity on clinical outcomes has not been previously investigated. METHODS: From the multicenter PTRG-DES (Platelet function and genoType-Related long-term prognosis in DES-treated patients) consortium, the patients were classified as preserved-EF (PEF: LVEF ≥ 50%) and reduced-EF (REF: LVEF< 5 0%) group by echocardiography. Platelet reactivity was measured using VerifyNow P2Y12 assay and high platelet reactivity (HPR) was defined as PRU ≥ 252. The major adverse cardiac and cerebrovascular events (MACCEs) were a composite of death, myocardial infarction, stent thrombosis and stroke at 5 years after PCI. Major bleeding was defined as Bleeding Academic Research Consortium bleeding types 3-5. RESULTS: A total of 13,160 patients from PTRG-DES, 9,319 (79.6%) patients with the results of both PRU and LVEF were analyzed. The incidence of MACCE and major bleeding was higher in REF group as compared with PEF group (MACCEs: hazard ratio [HR] 2.17, P < 0.001, 95% confidence interval [CI] 1.85-2.55; major bleeding: HR 1.78, P < 0.001, 95% CI 1.39-2.78). The highest rate of MACCEs was found in patients with REF and HPR, and the difference between the groups was statistically significant (HR 3.14 in REF(+)/HPR(+) vs. PEF(+)/HPR(-) group, P < 0.01, 95% CI 2.51-3.91). The frequency of major bleeding was not associated with the HPR in either group. CONCLUSION: LV dysfunction was associated with an increased incidence of MACCEs and major bleeding in patients who underwent PCI. The HPR status further exhibited significant increase of MACCEs in patients with LV dysfunction in a large, real-world registry. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04734028.

Association between toothbrushing and cardiovascular risk factors: a cross-sectional study using Korean National Health and Nutrition Examination Survey 2015-2017.

BACKGROUND: Previous studies have suggested that frequent toothbrushing is associated with a lower risk of future cardiovascular events. We sought to investigate further the relationship between toothbrushing, cardiovascular risk factors, and lifestyle behaviours. METHODS: We analysed a cross-sectional survey including 13,761 adults aged 30 years or older without a history of cardiovascular diseases from the Korean National Health and Nutritional Examination Survey. Conventional cardiovascular risk factors (blood pressure, lipid profiles, and fasting glucose), and inflammatory markers (high-sensitivity C-reactive protein [hsCRP], and white blood cell counts [WBC]) were investigated in relation to the frequency of toothbrushing. RESULTS: The estimated 10-year atherosclerotic cardiovascular disease (ASCVD) risk, calculated using the pooled cohort equations was 13.7%, 9.1%, and 7.3% for participants who reported toothbrushing 0-1, 2, and ≥ 3 times a day, respectively. Both conventional risk factors and inflammatory markers were significantly associated with frequent toothbrushing. However, after adjusting potential confounding factors such as age, sex, comorbidities, and lifestyle behaviours, only inflammatory markers were remained as significant factors. CONCLUSIONS: Oral hygiene behaviours are closely linked to cardiovascular risk factors. This study suggests that reduced systemic inflammatory burden may explain the benefit of improved oral hygiene in terms of cardiovascular risk.

Machine learning for predicting hepatitis B or C virus infection in diabetic patients.

Highly prevalent hepatitis B and hepatitis C virus (HBV and HCV) infections have been reported among individuals with diabetes. Given the frequently asymptomatic nature of hepatitis and the challenges associated with screening in some vulnerable populations such as diabetes patients, we conducted an investigation into the performance of various machine learning models for the identification of hepatitis in diabetic patients while also evaluating the significance of features. Analyzing NHANES data from 2013 to 2018, machine learning models were evaluated; random forest (RF), support vector machine (SVM), eXtreme Gradient Boosting (XGBoost), and least absolute shrinkage and selection operator (LASSO) along with stacked ensemble model. We performed hyperparameter tuning to improve the performance of the model, and selected important predictors using the best performance model. LASSO showed the highest predictive performance (AUC-ROC = 0.810) rather than other models. Illicit drug use, poverty, and race were highly ranked as predictive factors for developing hepatitis in diabetes patients. Our study demonstrated that a machine-learning-based model performed optimally in the detection of hepatitis among diabetes patients, achieving high performance. Furthermore, models and predictors evaluated from the current study, we expect, could be supportive information for developing screening or treatment methods for hepatitis care in diabetes patients.

Diagnostic Value of a Wearable Continuous Electrocardiogram Monitoring Device (AT-Patch) for New-Onset Atrial Fibrillation in High-Risk Patients: Prospective Cohort Study.

BACKGROUND: While conventional electrocardiogram monitoring devices are useful for detecting atrial fibrillation, they have considerable drawbacks, including a short monitoring duration and invasive device implantation. The use of patch-type devices circumvents these drawbacks and has shown comparable diagnostic capability for the early detection of atrial fibrillation. OBJECTIVE: We aimed to determine whether a patch-type device (AT-Patch) applied to patients with a high risk of new-onset atrial fibrillation defined by the congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, stroke, vascular disease, age 65-74 years, sex scale (CHA2DS2-VASc) score had increased detection rates. METHODS: In this nonrandomized multicenter prospective cohort study, we enrolled 320 adults aged ≥19 years who had never experienced atrial fibrillation and whose CHA2DS2-VASc score was ≥2. The AT-Patch was attached to each individual for 11 days, and the data were analyzed for arrhythmic events by 2 independent cardiologists. RESULTS: Atrial fibrillation was detected by the AT-Patch in 3.4% (11/320) of patients, as diagnosed by both cardiologists. Interestingly, when participants with or without atrial fibrillation were compared, a previous history of heart failure was significantly more common in the atrial fibrillation group (n=4/11, 36.4% vs n=16/309, 5.2%, respectively; P=.003). When a CHA2DS2-VASc score ≥4 was combined with previous heart failure, the detection rate was significantly increased to 24.4%. Comparison of the recorded electrocardiogram data revealed that supraventricular and ventricular ectopic rhythms were significantly more frequent in the new-onset atrial fibrillation group compared with nonatrial fibrillation group (3.4% vs 0.4%; P=.001 and 5.2% vs 1.2%; P<.001), respectively. CONCLUSIONS: This study detected a moderate number of new-onset atrial fibrillations in high-risk patients using the AT-Patch device. Further studies will aim to investigate the value of early detection of atrial fibrillation, particularly in patients with heart failure as a means of reducing adverse clinical outcomes of atrial fibrillation.

Performance of a Novel CT-Derived Fractional Flow Reserve Measurement to Detect Hemodynamically Significant Coronary Stenosis.

BACKGROUND: Fractional flow reserve (FFR) based on computed tomography (CT) has been shown to better identify ischemia-causing coronary stenosis. However, this current technology requires high computational power, which inhibits its widespread implementation in clinical practice. This prospective, multicenter study aimed at validating the diagnostic performance of a novel simple CT based fractional flow reserve (CT-FFR) calculation method in patients with coronary artery disease. METHODS: Patients who underwent coronary CT angiography (CCTA) within 90 days and invasive coronary angiography (ICA) were prospectively enrolled. A hemodynamically significant lesion was defined as an FFR ≤ 0.80, and the area under the receiver operating characteristic curve (AUC) was the primary measure. After the planned analysis for the initial algorithm A, we performed another set of exploratory analyses for an improved algorithm B. RESULTS: Of 184 patients who agreed to participate in the study, 151 were finally analyzed. Hemodynamically significant lesions were observed in 79 patients (52.3%). The AUC was 0.71 (95% confidence interval [CI], 0.63-0.80) for CCTA, 0.65 (95% CI, 0.56-0.74) for CT-FFR algorithm A (P = 0.866), and 0.78 (95% CI, 0.70-0.86) for algorithm B (P = 0.112). Diagnostic accuracy was 0.63 (0.55-0.71) for CCTA alone, 0.66 (0.58-0.74) for algorithm A, and 0.76 (0.68-0.82) for algorithm B. CONCLUSION: This study suggests the feasibility of automated CT-FFR, which can be performed on-site within several hours. However, the diagnostic performance of the current algorithm does not meet the a priori criteria for superiority. Future research is required to improve the accuracy.

Impact of dementia and drug compliance on patients with acute myocardial infarction.

BACKGROUND: In South Korea, the number of people with dementia is rising at a worrisome rate, and many of them also have acute myocardial infarction (AMI), a disease with a high mortality rate. HYPOTHESIS: We speculated that dementia and drug compliance have significant impact on the mortality of patients with AMI. METHODS: The study derived data from the National Health Insurance Service-Senior for a retrospective cohort study. The total number of patients diagnosed with AMI for the first time between 2007 and 2013 was 16 835, among whom 2021 had dementia. Medication possession ratio (MPR) was used to assess medication adherence. RESULTS: AMI patients with dementia had unfavorable baseline characteristics; they had significantly higher risk of all-cause mortality (hazard ratio [HR]: 2.49; 95% confidence interval [CI]: 2.34-2.66; p < .001) and lower MPR (aspirin: 21.9% vs. 42.8%; p < .001). AMI patients were stratified by presence of dementia and medication adherence, and the survival rate was the highest among those with no dementia and good adherence, followed by those with no dementia and poor adherence, those with dementia and good adherence, and those with dementia and poor adherence. The multivariable analysis revealed that dementia (HR: 1.64; 95% CI: 1.53-1.75; p < .001) and poor adherence to medication (HR: 1.60; 95% CI: 1.49-1.71; p < .001) had a significant association with all-cause mortality in AMI patients. CONCLUSIONS: AMI patients with dementia have a higher mortality rate. Their prognosis is negatively affected by their poorer medication adherence than patients without dementia.

Predictive Value of Electromechanical Window for Risk of Fatal Ventricular Arrhythmia.

BACKGROUND: As an indicator of electro-mechanical coupling, electromechanical window (EMW) can be used to predict fatal ventricular arrhythmias. We investigated the additive effect of EMW on the prediction of fatal ventricular arrhythmias in high-risk patients. METHODS: We included patients who had implantable cardioverter-defibrillator (ICD) implanted for primary or secondary prevention. The event group was defined as those who received an appropriate ICD therapy. We acquired echocardiograms at ICD implantation and follow-up. The EMW was calculated as the difference between the interval from QRS onset to aortic valve closure and QT interval from the electrocardiogram embedded in the continuous wave doppler image. We evaluated the predictive value of EMW for predicting fatal ventricular arrhythmia. RESULTS: Of 245 patients (67.2 ± 12.8 years, 63.7% men), the event group was 20.0%. EMW at baseline (EMW-Baseline) and follow-up (EMW-FU) was significantly different between event and control groups. After adjustment, both EMW-Baseline (odds ratio [OR]adjust 1.02 [1.01-1.03], P = 0.004) and EMW-FU (ORadjust 1.06 [1.04-1.07], P < 0.001) remained as significant predictors for fatal arrhythmic events. Adding EMW-Baseline significantly improved the discriminating ability of the multivariable model including clinical variables (area under the curve [AUC] 0.77 [0.70-0.84] vs. AUC 0.72 [0.64-0.80], P = 0.004), while a univariable model using EMW-FU alone showed the best performance among models (AUC 0.87 [0.81-0.94], P = 0.060 against model with clinical variables; P = 0.030 against model with clinical variables and EMW-Baseline). CONCLUSION: The EMW could effectively predict severe ventricular arrhythmia in ICD implanted patients. This finding supports the importance of incorporating the electro-mechanical coupling index into the clinical practice for predicting future fatal arrhythmia events.

Accuracy of Artificial Intelligence-Based Automated Quantitative Coronary Angiography Compared to Intravascular Ultrasound: Retrospective Cohort Study.

BACKGROUND: An accurate quantitative analysis of coronary artery stenotic lesions is essential to make optimal clinical decisions. Recent advances in computer vision and machine learning technology have enabled the automated analysis of coronary angiography. OBJECTIVE: The aim of this paper is to validate the performance of artificial intelligence-based quantitative coronary angiography (AI-QCA) in comparison with that of intravascular ultrasound (IVUS). METHODS: This retrospective study included patients who underwent IVUS-guided coronary intervention at a single tertiary center in Korea. Proximal and distal reference areas, minimal luminal area, percent plaque burden, and lesion length were measured by AI-QCA and human experts using IVUS. First, fully automated QCA analysis was compared with IVUS analysis. Next, we adjusted the proximal and distal margins of AI-QCA to avoid geographic mismatch. Scatter plots, Pearson correlation coefficients, and Bland-Altman were used to analyze the data. RESULTS: A total of 54 significant lesions were analyzed in 47 patients. The proximal and distal reference areas, as well as the minimal luminal area, showed moderate to strong correlation between the 2 modalities (correlation coefficients of 0.57, 0.80, and 0.52, respectively; P<.001). The correlation was weaker for percent area stenosis and lesion length, although statistically significant (correlation coefficients of 0.29 and 0.33, respectively). AI-QCA tended to measure reference vessel areas smaller and lesion lengths shorter than IVUS did. Systemic proportional bias was not observed in Bland-Altman plots. The biggest cause of bias originated from the geographic mismatch of AI-QCA with IVUS. Discrepancies in the proximal or distal lesion margins were observed between the 2 modalities, which were more frequent at the distal margins. After the adjustment of proximal or distal margins, there was a stronger correlation of proximal and distal reference areas between AI-QCA and IVUS (correlation coefficients of 0.70 and 0.83, respectively). CONCLUSIONS: AI-QCA showed a moderate to strong correlation compared with IVUS in analyzing coronary lesions with significant stenosis. The main discrepancy was in the perception of the distal margins by AI-QCA, and the correction of margins improved the correlation coefficients. We believe that this novel tool could provide confidence to treating physicians and help in making optimal clinical decisions.

Hepatitis Risk in Diabetes Compared to Non-Diabetes and Relevant Factors: A Cross-Sectional Study with National Health and Nutrition Examination Survey (NHANES), 2013-2018.

This study aimed to identify the development of hepatitis B or C infection in diabetes patients compared to those without and to elucidate factors associated with the prevalence of hepatitis B or C infection in diabetes. We conducted a cross-sectional study using data from the National Health and Nutrition Examination Survey (NHANES) 2013-2018. As evaluation factors, we included variables such as age, race, illicit drug use, and poverty. The diabetic group had a significantly higher prevalence of hepatitis B or C infection than the non-diabetic group (odds ratio (OR) = 1.73; 95% confidence interval (CI), 1.36-2.21, p < 0.01). In multivariate Cox regression, non-poverty and non-illicit drug use were lower risk factors contributing to hepatitis development in diabetes (hazard ratio (HR) = 0.50; 95% CI, 0.32-0.79, p < 0.01, and HR = 0.05; 95% CI, 0.03-0.08, p < 0.01, respectively). Logistic regression also showed that these factors were significant contributors to hepatitis development in the diabetic group (p < 0.01). In patients with diabetes, the development of hepatitis was higher than that in those without, and hepatitis development was influenced by poverty and illicit drug use. This may provide supporting evidence of response strategies for diabetes to care for hepatitis development in advance.

Cumulative Alcohol Consumption Burden and the Risk of Stroke in Young Adults: A Nationwide Population-Based Study.

BACKGROUND AND OBJECTIVE: Alcohol consumption is one of the important modifiable risk factors for stroke in young adults. The association between the cumulative burden of alcohol consumption and its impact on incident stroke in young adults is unknown. We aimed to investigate the association between cumulative alcohol burden and the risk for stroke among young adults. METHODS: Using data from the Korean National Health Insurance Service database, patients age between 20 and 39 years, who underwent 4 consecutive annual health examinations between 2009 and 2012, were included. The cumulative alcohol burden score of moderate-to-heavy drinking was evaluated by assigning a score of 1 for alcohol consumption ≥105 g/wk at the health examination each year and calculating the sum of 4 years (0-4). The main outcome was incident stroke and its subtypes, ischemic stroke, and hemorrhagic stroke during the follow-up period. RESULTS: Of 1 536 668 patients (mean age of 29.5 years, 71.5% male, and median follow-up of 6-year), 3 153 experienced an incident stroke (incidence rate, 0.37 per 1,000 person-years). After multivariable adjustment, patients with alcohol burden scores of 2, 3, and 4, who consumed more than 105 g/wk of alcohol for 2, 3, and 4 years, demonstrated significantly higher risks for stroke (hazard ratio [HR] 1.19, 95% CI 1.05-1.34 for 2; HR 1.22, 95% CI 1.09-1.38 for 3; HR 1.23, 95% CI 1.10-1.38 for 4) compared with those with a burden score of 0. This positive dose-response relationship was primarily driven by hemorrhagic rather than ischemic stroke. High alcohol burden scores (i.e., 2, 3, and 4) were significantly associated with higher risks for hemorrhagic stroke (HR 1.30, 95% CI 1.10-1.54 for 2; HR 1.42, 95% CI 1.21-1.67 for 3; HR 1.36, 95% CI 1.16-1.59 for 4) compared with a burden score of 0. DISCUSSION: Young adults who engaged in moderate-to-heavy drinking demonstrated a higher risk for incident stroke, especially hemorrhagic stroke. Reducing alcohol consumption should be emphasized in young adults with heavy drinking habits as part of any stroke prevention strategy.

Market potential and value-added opportunities of cold-hardy berries and small fruits in the Intermountain West, USA.

Novel cold-hardy berries and small fruits represent an opportunity for growers in the Intermountain West, USA, as the harsh environment is not suited for other common berries and small fruits. This study analyzed the fresh market and value-added potential of haskap berries (Lonicera caerulea), saskatoon berries (Amelenchier alnifolia), and dwarf sour cherry (DSC) fruit (Prunus x kerrasis) by instrumental and consumer studies. Fresh and 2-week stored haskap (cv. Aurora), saskatoon (Lee 3), and DSC (Romeo) were measured for fruit weight, flesh firmness, bulk titratable acidity, pH, and soluble solid content. Participants (n = 115) in at-home sensory tests scored these fruits for overall liking (OL, 9-point hedonic scale), purchase intent (PI, 5-point scale), and willingness-to-pay (WTP, 5-point scale). Ten participants further shared insight on these fruits in focus groups. Instrumental testing found a significant decrease in flesh firmness for 2-week stored haskap, but the consumers' OL was still comparable to fresh haskap. The fresh and 2-week stored haskap received significantly higher OL, PI, and WTP scores (7.7 ± 1.0, 3.8 ± 1.0, and $3.7 ± 1.0; 7.7 ± 1.2, 3.8 ± 1.1, and $3.7 ± 1.0, respectively) compared to saskatoon (6.1 ± 1.8, 2.8 ± 1.1, and $3.0 ± 0.9, respectively) and DSC (5.6 ± 2.2, 2.5 ± 1.2, and $3.1 ± 1.0, respectively) (α = 0.05). The focus groups indicated that participants want to support local produce. The participants expressed interest in fresh unprocessed haskap berries, but preferred saskatoon and DSC in different value-added formats. Hence, this study concluded that there is an untapped fresh-market potential for haskap berries and there are value-added opportunities to extend the sale season and improve the palatability of saskatoon and DSC. PRACTICAL APPLICATION: This research has examined consumer perception of three species of novel small fruits by determining fresh-market potential and linking this to the opportunity for value-added product development. For haskap berries, the study not only indicated fresh market potential, but for the cultivar Aurora, consumer liking was not meaningfully altered by 2 weeks of cold storage. These results are meaningful because they will assist growers in the Intermountain West with market planning, including the possibility of formulating products that utilize these novel crops. This study provides growers the opportunity to diversify their income stream by utilizing local produce.

BioMatrix Versus Orsiro Stents for Coronary Artery Disease: A Multicenter, Randomized, Open-Label Study.

BACKGROUND: Comparative studies of ultrathin-strut biodegradable polymer sirolimus-eluting stent (BP-SES) have reported promising results and validated its excellent outcomes in terms of safety and efficacy. However, there are limited studies comparing BP drug-eluting stents with struts of different thicknesses. We compared the long-term clinical outcomes of patients treated with an ultrathin-strut BP-SES or a thick-strut biodegradable polymer biolimus-eluting stent (BP-BES). METHODS: The BIODEGRADE trial (Biomatrix and Orsiro Drug-Eluting Stents in Angiographic Result in Patients With Coronary Artery Disease) is a multicenter prospective randomized study comparing coronary revascularization in patients with ultrathin-strut BP-SES and thick-strut BP-BES with the primary end point of target lesion failure at 18 months posttreatment. We performed the prespecified analysis of 3-year clinical outcomes. RESULTS: In total, 2341 patients were randomized to receive treatment with ultrathin-strut BP-SES (N=1175) or thick-strut BP-BES (N=1166). The 3-year incidence rate of target lesion failure was 3.2% for BP-SES and 5.1% for BP-BES (P=0.023). The difference was primarily due to differences in ischemia-driven target lesion revascularization (BP-SES, 1.5%; BP-BES, 2.8%; P=0.035) between groups. A landmark analysis of the late follow-up period showed significant differences in target lesion failure, with outcomes being better in BP-SES. Cardiac death and target lesion revascularization were significantly lower in the BP-SES group. CONCLUSIONS: In a large, randomized trial, the long-term clinical outcome of target lesion failure at 3 years was significantly better among patients treated with the ultrathin-strut BP-SES. The results indicate the superiority of the ultrathin-strut BP-SES compared with the thick-strut BP-BES. REGISTRATION: URL: https://clinicaltrials.gov; Unique identifier: NCT02299011.

Catheter ablation and thoracoscopic ablation in long persistent atrial fibrillation with large left atrium.

Background: Pulmonary vein antrum isolation (PVAI) is the cornerstone of atrial fibrillation (AF) ablation, but the clinical outcomes of PVAI are unsatisfactory in patients with persistent AF and a large left atrium (LA). Objectives: We investigated the clinical outcomes following radiofrequency ablation (RFCA), cryoballoon ablation (CBA), and thoracoscopic maze in patients with persistent AF and a large LA. Methods: We included patients with consecutive persistent AF who had a large LA (LA diameter >50 mm) and underwent RFCA, CBA, or thoracoscopic maze surgery. In the RFCA group, additional linear ablation was performed at the physician's discretion. The endpoint was 12 months without recurrence of an atrial arrhythmia, including AF, atrial flutter, and atrial tachycardia, following a 90-day blanking period. Results: We recruited 89 persistent AF patients with a large LA who underwent RFCA (n = 32), CBA (n = 38), or the thoracoscopic maze procedure (n = 19). During the 12-month follow-up, 48 (53.9%) cases of AF recurrence were observed. There was no prognostic difference between groups (50.0% in RFCA vs. 52.6% in CBA vs. 63.2% in thoracoscopic maze, all P > 0.05). Early recurrence during the blanking period was a significant predictor of late recurrence for RFCA and CBA, but not for the thoracoscopic maze. Conclusion: In persistent AF patients with a large LA, we did not find a prognostic difference RFCA, CBA, or a thoracoscopic maze procedure in recurrence of atrial arrhythmia. Early recurrence predicted late recurrence in catheter ablation, but not in thoracoscopic maze.

Reverse Remodeling Assessed by Left Atrial and Ventricular Strain Reflects Treatment Response to Sacubitril/Valsartan.

BACKGROUND: The left ventricular global longitudinal strain (LVGLS) and left atrial reservoir strain (LARS) are considered as sensitive and reliable markers of cardiac remodeling and function. However, their temporal changes during optimal management of heart failure with reduced ejection fraction (HFrEF) are unknown. OBJECTIVES: This study investigated the time trajectories of the LARS and LVGLS in patients with HFrEF treated with angiotensin receptor-neprilysin inhibitors, and assessed whether the LARS and LVGLS could define left heart reverse remodeling (LHRR) and reflect the treatment response and prognosis. METHODS: Using a retrospective cohort of patients with HFrEF prescribed sacubitril/valsartan, we assessed the time trajectories of the LVGLS and LARS in 409 patients (1,258 echocardiograms), and investigated their association with the occurrence of cardiovascular death and hospitalization for heart failure (HHF), after the determination of LHRR, during a median follow-up of 27.1 (IQR: 18.3-36.3) months. RESULTS: Among patients with HFrEF prescribed sacubitril/valsartan, both the LVGLS and LARS improved over time. The improvements in the LVGLS and LARS were prominent within 6 months of sacubitril/valsartan treatment: the LVGLS improved from 10.2% (IQR: 7.9%-12.7%) to 13.9% (IQR: 10.5%-16.3%) (P < 0.001), and the LARS improved from 11.4% (IQR: 8.4%-15.6%) to 15.9% (IQR: 11.5%-21.4%) (P < 0.001). These improvements were larger among patients who did not experience the study outcome than in patients with events. Improvement in the LVGLS to ≥13% and LARS to ≥12.5% (ie, complete LHRR) was significantly associated with a lower risk of cardiovascular death and HHF, and this association was stronger than that of changes in other conventional echocardiographic parameters. CONCLUSIONS: In patients with HFrEF treated with sacubitril/valsartan, the LVGLS and LARS were improved, typically within 6 months of treatment. Complete LHRR, defined by improvement in the LVGLS and LARS, can be an indicator of treatment response and prognosis.

Surveillance of Arrhythmia in Patients After Myocardial Infarction Using Wearable Electrocardiogram Patch Devices: Prospective Cohort Study.

BACKGROUND: Acute myocardial infarction may be associated with new-onset arrhythmias. Patients with myocardial infarction may manifest serious arrhythmias such as ventricular tachyarrhythmias or atrial fibrillation. Frequent, prolonged electrocardiogram (ECG) monitoring can prevent devastating outcomes caused by these arrhythmias. OBJECTIVE: We aimed to investigate the incidence of arrhythmias in patients following myocardial infarction using a patch-type device-AT-Patch (ATP-C120; ATsens). METHODS: This study is a nonrandomized, single-center, prospective cohort study. We evaluated 71 patients who had had a myocardial infarction and had been admitted to our hospital. The ATP-C120 device was attached to the patient for 11 days and analyzed by 2 cardiologists for new-onset arrhythmic events. RESULTS: One participant was concordantly diagnosed with atrial fibrillation. The cardiologists diagnosed atrial premature beats in 65 (92%) and 60 (85%) of 71 participants, and ventricular premature beats in 38 (54%) and 44 (62%) participants, respectively. Interestingly, 40 (56%) patients showed less than 2 minutes of sustained paroxysmal atrial tachycardia confirmed by both cardiologists. Among participants with atrial tachycardia, the use of ß-blockers was significantly lower compared with patients without tachycardia (70% vs 90%, P=.04). However, different dosages of ß-blockers did not make a significant difference. CONCLUSIONS: Wearable ECG monitoring patch devices are easy to apply and can correlate symptoms and ECG rhythm disturbances in patients following myocardial infarction. Further study is necessary regarding clinical implications and appropriate therapies for arrhythmias detected early after myocardial infarction to prevent adverse outcomes.

The Role of Beliefs, Pride, and Perceived Barriers in Decision-Making Regarding Purchasing Value-Added Pulse Products among US Consumers.

This study explores the underlying psychological structure of purchasing value-added pulse products. It expands the theory of planned behavior (TPB) model by incorporating an emotional factor and explains consumers' attitudes and subsequent behavioral intentions in the context of value-added pulse products (VAPPs). The study results showed the significant effect of pride on the purchase intention of value-added pulse products, as well as the moderating effect of perceived barriers on some of the relationships among the variables. Although value-added pulse products are emerging as a means of income maximization in the agri-food industry, there is a lack of understanding about consumers who purchase these products. This study fills the gap by developing a research framework for agriculture-related businesses. The findings may provide further insights into consumers' attitudes and behaviors in consuming agri-foods, thereby assisting pulse producers and marketers to develop a more effective marketing strategy.

Bleeding risk in patients with atrial fibrillation treated with combined anti-platelet and non-vitamin K antagonist oral anticoagulant therapy.

BACKGROUND: The use of non-vitamin K antagonist oral anticoagulants (NOACs) in patients with non-valvular atrial fibrillation (AF) has been increasing. Accordingly, the combined use of antiplatelet agents (APT) and NOAC therapy is commonly encountered in clinical practice. The purpose of this study was to compare the clinical outcomes between combination therapy (NOAC and APT) vs. monotherapy (NOAC only) in patients with AF. METHODS: We retrospectively analyzed patients who were prescribed NOACs between January 2012 and December 2016. The primary outcome was major bleeding and any bleeding events, and the secondary outcomes were stroke/systemic embolic (SE) events and major adverse cardiac events (MACE). RESULTS: Of the 1068 participants, there were 264 (24.7%) patients in the combination therapy group. The prevalence of diabetes (p = 0.017) and history of stroke and transient ischemic attacks (p < 0.001) was higher in the combination group than in the monotherapy group. During the mean 14.6 ± 9.8 months of follow-up, the incidence of any bleeding was significantly higher in the combination therapy group than in the monotherapy group (p < 0.001). The rate of major bleeding, stroke/SE, and MACE between the two groups was similar. The rate of under-dosage NOAC prescriptions was higher in the combination therapy group than in the monotherapy group (p = 0.024). CONCLUSIONS: The combination therapy group had higher incidences of any bleeding events compared to the monotherapy in patients with appropriate dosing. However, there was no difference in stroke/SE, and MACE. The bleeding risk in AF patients taking the combination of NOACs and APT should be carefully evaluated.
