Cardiac magnetic resonance image-based classification of the risk of arrhythmias in post-myocardial infarction patients

Conclusion These promising results suggest that the discriminative features introduced in this paper can be used by medical professionals, or in automatic decision support systems, along with the recognized risk markers, to improve arrhythmic risk stratification in post-MI patients.

PATIENTS UNDERGOING cardiac surgery are at risk for cardiovascular collapse from a variety of pathologies including, but not limited to, hemorrhage, tamponade, myocardial infarction, arrhythmias, or cardiogenic shock. Tension pneumothorax is a rare complication after cardiac surgery and requires prompt recognition and treatment. The subsequent case report describes an occurrence of tension pneumothorax and hemodynamic instability after the use of an airway exchange catheter (AEC) to extubate and reintubate a patient with a difficult airway following cardiac surgery.

A 50-year-old man was referred to our hospital for VT. He underwent mechanical aortic and mitral valve replacement for infective endocarditis and embolic myocardial infarction in the left ventricular inferior wall during a surgery. Anti-arrhythmia drugs (AADs) such as sotalol and bisoprolol were initiated and implantable c...

ICIs have been shown to provide significant mortality benefits for cancer patients, but they are also associated with immune-mediated toxicity. Unlike most immune-related adverse events, which are a common occurrence, reversible and can be treat...

ConclusionSome non ‐invasive risk factors were linked to the scar areas, but few were significantly modified after ablation. Larger populations are needed to demonstrate significant differences or correlations.This article is protected by copyright. All rights reserved.

Abstract BACKGROUND: Although there are guidelines that recommend an early invasive strategy in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) and concomitant congestive heart failure (CHF), optimal timing of the invasive strategy remains controversial. METHODS: Among 2045 patients who were admitted owing to NSTE-ACS or CHF, 300 presented with NSTE-ACS and concomitant CHF. Of the 300 patients, we enrolled 160 patients for whom coronary angiography (CAG) during their hospital stay was planned at the time of admission; 64 of these patients were classified into the early invasive group (

Abstract Background and objectives: Modern-day epidemiologic data on the risk and shifting landscape of occurrence of cardiovascular events in cannabis users remain inadequate and rather conflicting, especially amongst the young adult population. Furthermore, the problem of polysubstance use among youth is challenging for healthcare professionals and policy-makers. Previous studies report higher risk of concomitant use of tobacco, alcohol, cocaine, and amphetamine in young cannabis users. However, most of these studies did not eliminate the confounding effects of concomitant other substance abuse while assessing t...

This study characterized cardiac changes in histology and gene expression in rats exposed this model. Male rats were subjected to two cat exposures (separated by a period of 10 d) and daily cage-mate changes for 31 d. Control rats were not exposed to the cat or cage-mate changes. Ventricular tissue was analyzed by RNA sequencing, western blotting, histology, and immunohistochemistry. Multifocal lesions characterized by necrosis, mononuclear cell infiltration, and collagen deposition were observed in hearts from all stressed rats but none of the control rats. Gene expression analysis identified clusters of upregul...
