similar results as the previous real-life study; however, we had some different results, such as the GIS tract bleeding was more frequent in patients receiving dabigatran 110 mg bid. The major and intracranial bleeding events were similar for different DOACs; and among DOACs, only rivaroxaban 20 mg od was associated with a high risk of bleeding.

Although patients with prosthetic heart valves have an increased risk of clinically overt cerebrovascular events, evidence for the risk of silent cerebral infarction (SCI) is scarce. Serum neuron-specific enolase (NSE) is suggested to be a valid biomarker that allows for the quantification of the degree of neuronal injury. We aimed to assess whether NSE is elevated as a marker of recent SCI in patients with a prosthetic mitral valve.

We measured the NSE levels in 103 patients with a prosthetic mitral valve (PMV), admitted to our outpatient clinics for routine evaluation. International normalized ratio (INR) and time in target therapeutic range (TTR) were noted as anticoagulation quality measures.

Most of the patients were females (58%), and a mean age was 65 years. NSE values of >12 ng/mL, suggesting a recent SCI, was detected in 25 patients (24%). NSE was negatively correlated with admission INR (r=-0.307, p=0.002). Multivariate analyses demonstrated subtherapeutic INR (INR <2.5) and suboptimal TTR as independent predictors of SCI [odds ratio (OR) 5.420; 95% confidence interval (CI) 1.589 to 18.483; p=0.007, and OR 4.149; 95% CI 1.019 to 16.949; p=0.047, respectively]. Being a current smoker (OR 10.798; 95% CI 2.520 to 46.272; p=0.001), large left atrium (OR 6.763; 95% CI 2.253 to 20.302; p=0.001), and not using aspirin (OR 10.526; 95% CI 1.298 to 83.333; p=0.027) were other independent predictors.

Our data suggest that silent brain infarcts are very prevalent among patients with a PMV, as one fourth of them had the event during their routine outpatient visit. Poor quality of anticoagulation partly explains the increased prevalence.

The effects of treatment of coronavirus disease 2019 (COVID-19) with a triple combination composed of hydroxychloroquine, an an-tiviral, and an antibiotic on electrocardiography (ECG) parameters in patients with mild-to-moderate symptoms are not wholly understood. We aimed to explore the changes in ECG parameters after treatment with triple combination therapy in patients with mild-to-moderate symptomatic COVID-19.

This retrospective, single-center case series analyzed 91 patients with mild-to-moderate symptomatic COVID-19 at Ankara Gazi Mus-tafa Kemal State Hospital of Ankara City, Turkey, from April 1, 2020, to April 30, 2020. Forty-three patients were treated with hydroxychloroquine+oseltamivir+azithromycin (Group 1) and 48 patients were treated with hydroxychloroquine+oseltamivir+levofloxacin (Group 2). Heart rate, P wave duration, P wave dispersion, PR interval, QRS duration, corrected QT interval (QTc), QTc dispersion (QTD), delta QTc, Tp-e, Tp-e dispersion, and Tp-e/QTc ratio were all calculated frs a significant decrease in the QTD after the treatment in patients who were taking triple therapy including azithromycin.
To the best of our knowledge, this study is the first to investigate QT prolongation in a population of COVID-19 patients treated with triple combination therapy. We found that there was a significant decrease in the QTD after the treatment in patients who were taking triple therapy including azithromycin.
Distal radial artery access or trans-snuffbox access (TSA) is a novel, safe, and feasible technique for coronary artery interventions wherein its vascular hemostasis is still concerned. So, this study aimed to compare two homeostasis methods comprising manual and mechanical compression approaches in patients undergoing coronary angiography (CAG) via TSA.

In a prospective nonrandomized clinical trial, a total of 80 patients undergoing diagnostic CAG by TSA were divided into two equal groups manual compression and mechanical compression (using radial TR band), the main end point of which was primary hemostasis time. Other variables were patient satisfaction, puncture site pain severity, hospitalization time, and local neurovascular complication during the 30-day follow-up.

The mean age of the patients was 57.1±8.0 years, with 40 of them (54.1%) being male. The primary hemostasis time was significantly shorter in the manual compression approach [15.0±5.9 minutes with median 15 (9-20)] than in the TR band group [25.7±4.9 minutes with median 25 (20-30)] (p<0.001). No significant difference was noted in the patient's satisfaction and puncture site pain severity as well as hospitalization time between the two methods (p>0.050). link2 The neurovascular complication, including hematoma, numbness, and dRA occlusion, rates had also no significant difference between the two groups (p>0.050).

The manual compression approach on the puncture site reduces hemostasis time in patients undergoing CAG via TSA when compared with the mechanical compression method.

Left bundle branch block (LBBB), which is associated with underlying cardiac disease, is believed to play a role in the pathogenesis of cardiomyopathy through delays in interventricular conduction, leading to dyssynchrony. However, this has not been established in previous studies. It is unclear whether LBBB indicates clinically advanced cardiac disease or is an independent factor responsible for increased mortality and the development of heart failure. We investigated the natural history of isolated LBBB without any associated structural heart disease in order to determine its clinical significance.

We performed a retrospective chart review on consecutive patients who fulfilled the 12-lead electrocardiographic (ECG) criteria for complete LBBB and had a normal echocardiogram with no evidence of structural heart disease and left or right ventricular systolic dysfunction within three months of the initial ECG between January 1, 2000 and December 31, 2009. We excluded patients with documented coronary arteryrate and incidence of cardiomyopathy.
Many trials confirmed the role of sacubitril-valsartan in the treatment of patients with heart failure with reduced ejection fraction (HFrEF). However, there is no sufficient data to register the effect of compulsory discontinuation of sacubitril-valsartan, either because of finan-cial shortage or adverse effects, and shifting to the standard therapy, including angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB).

The patients with HFrEF (LVEF ≤35%) were included in the study. They received treatment with sacubitril-valsartan as a replacement for an ACEI or ARB. The patients were divided into two groups the compliant group (n=111). The non-compliant group (n=82), whose members discontinued sacubitril-valsartan after ≥5 months but <6 months since their enrollment in the study.

Initially, 199 patients with HFrEF were included in the study. All the patients were started treatment with sacubitril-valsartan in addition to the evidence-based standard therapy of heart failuref the functional class. The decline in LVEF and NYHA functional class occurs despite being compliant with the optimal conventional therapy with ACEI or evidence-based ARB.
The discontinuation of sacubitril-valsartan in patients with HFrEF leads to deterioration of the LVEF as well as worsening of the functional class. The decline in LVEF and NYHA functional class occurs despite being compliant with the optimal conventional therapy with ACEI or evidence-based ARB.The ST-elevation myocardial infarction (STEMI)/non-STEMI paradigm per the current guidelines has important limitations. It misses a substantial proportion of acute coronary occlusions (ACO) and results in a significant amount of unnecessary catheterization laboratory activations. It is not widely appreciated how poor is the evidence base for the STEMI criteria; the recommended STEMI cutoffs were not derived by comparing those with ACO with those without and not specifically designed for distinguishing patients who would benefit from emergency reperfusion. This review aimed to discuss the origins, evidence base, and limitations of STEMI/non-STEMI paradigm and to call for a new paradigm shift to the occlusion MI (OMI)/non-OMI.Coronary artery disease (CAD) together with stroke are the leading causes of death worldwide, and together, they pre-sent a health and economic burden. Ischemic stroke survivors and patients who suffered transient ischemic attack (TIA) have a higher prevalence of coronary atherosclerosis, and they have a relatively high risk of myocardial infarcti-on and nonstroke vascular death. Pubmed was searched for studies focused on investigating coronary atherosclerosis in ischemic stroke survivors or patients who suffered TIA and their cardiovascular risk assessment. There were corona-ry plaques in 48%-70% of stroke survivors without a known history of CAD, and significant stenosis of at least one coronary artery can be found in 31% of these patients. CAD is a major cause of morbidity and mortality in stroke survivors. Detection and treatment of silent CAD may improve the long-term outcome and survival of these patients.Multi-view classification with limited sample size and data augmentation is a very common machine learning (ML) problem in medicine. With limited data, a triplet network approach for two-stage representation learning has been proposed. However, effective training and verifying the features from the representation network for their suitability in subsequent classifiers are still unsolved problems. Although typical distance-based metrics for the training capture the overall class separability of the features, the performance according to these metrics does not always lead to an optimal classification. Consequently, an exhaustive tuning with all feature-classifier combinations is required to search for the best end result. To overcome this challenge, we developed a novel nearest-neighbor (NN) validation strategy based on the triplet metric. This strategy is supported by a theoretical foundation to provide the best selection of the features with a lower bound of the highest end performance. The proposed strategy is a transparent approach to identify whether to improve the features or the classifier. link3 This avoids the need for repeated tuning. Our evaluations on real-world medical imaging tasks (i.e., radiation therapy delivery error prediction and sarcoma survival prediction) show that our strategy is superior to other common deep representation learning baselines [i.e., autoencoder (AE) and softmax]. The strategy addresses the issue of feature's interpretability which enables more holistic feature creation such that the medical experts can focus on specifying relevant data as opposed to tedious feature engineering.
