Label-free evaluation of myocardial infarct in surgically excised ventricular myocardium by Raman spectroscopy [PDF]
arXiv, 2018 Understanding the viability of the ischemic myocardial tissue is a critical issue in determining the appropriate surgical procedure for patients with chronic heart failure after myocardial infarction (MI). Conventional MI evaluation methods are; however, preoperatively performed and/or give an indirect information of myocardial viability such as shape,

Evaluation of deep learning-based myocardial infarction quantification using Segment CMR software [PDF]
arXiv, 2020 This work evaluates deep learning-based myocardial infarction (MI) quantification using Segment cardiovascular magnetic resonance (CMR) software. Segment CMR software incorporates the expectation-maximization, weighted intensity, a priori information (EWA) algorithm used to generate the infarct scar volume, infarct scar percentage, and microvascular ...

Harnessing Outer Space for Improved Electrocaloric Cooling
Advanced Functional Materials, EarlyView.A novel radiative heat sink/source‐integrated electrocaloric (R‐iEC) system combines the electrocaloric (EC) effect with a thermally conductive radiative cooler (TCRC) to address heat dissipation limitations in EC devices. Utilizing outer space as a heat sink, the system achieves up to 240 W m−2 of heat dissipation performance, making it highly ...

The Biological Basis for Cardiac Repair After Myocardial Infarction: From Inflammation to Fibrosis.
Circulation Research, 2016 In adult mammals, massive sudden loss of cardiomyocytes after infarction overwhelms the limited regenerative capacity of the myocardium, resulting in the formation of a collagen-based scar.

Advanced Functional Materials, EarlyView.In this work, melt electrowriting is used to fabricate a 3D printed scaffold design that generates engineered cardiac tissues with in‐plane contraction, mimicking natural myocardium. It is shown that these tissues display advanced maturation and functionality.

Myocardial infarction in a teenager [PDF]
European Heart Journal, 2014 An 18-year-old male presented to the Emergency Department with a 3-h history of chest pain. On physical examination, he had a blood pressure of 150/95 mmHg, mild obesity, and otherwise normal examination. An electrocardiogram showed sinus rhythm with short PR interval, ventricular preexcitation, and non-specific repolarization abnormalities …

Red blood cell eNOS is cardioprotective in acute myocardial infarction
Redox Biology, 2022 Red blood cells (RBCs) were shown to transport and release nitric oxide (NO) bioactivity and carry an endothelial NO synthase (eNOS). However, the pathophysiological significance of RBC eNOS for cardioprotection in vivo is unknown.

Cascaded Framework for Automatic Evaluation of Myocardial Infarction from Delayed-Enhancement Cardiac MRI [PDF]
arXiv, 2020 Automatic evaluation of myocardium and pathology plays an important role in the quantitative analysis of patients suffering from myocardial infarction. In this paper, we present a cascaded convolutional neural network framework for myocardial infarction segmentation and classification in delayed-enhancement cardiac MRI.
