Neuroimaging for differential diagnosis of transient neurological attacks

Brain and Behavior, Volume 12, Issue 12, December 2022., 2022
Abstract Background Rapid yet comprehensive neuroimaging protocols are required for patients with suspected acute stroke. However, stroke mimics can account for approximately one in five clinically diagnosed acute ischemic strokes and the rate of thrombolyzed mimics can be as high as 17%.

Comorbid CAD and Ventricular Hypertrophy Compromise The Perfusion of Myocardial Tissue at Subcritical Stenosis of Epicardial Coronaries [PDF]

, 2018
BACKGROUND: Most studies of CAD revascularization have been based on and reported according to angiographic criteria which don't consider the relation between the resulting effective flow distal to the stenosis and the demand of a hypertrophied myocardial tissue.

Isovolumetric Contraction as a Marker of Ventricular Performance in Patients with Afterload Mismatch

Diagnostics, 2023
Introduction: The evaluation of myocardial contractility is essential in cardiology practice. The gold standard for this evaluation is the end-systolic elastance, but it the method involved is complex.

Deep Learning for Cardiologist-level Myocardial Infarction Detection in Electrocardiograms [PDF]

, 2019
Myocardial infarction is the leading cause of death worldwide. In this paper, we design domain-inspired neural network models to detect myocardial infarction. First, we study the contribution of various leads. This systematic analysis, first of its kind in the literature, indicates that out of 15 ECG leads, data from the v6, vz, and ii leads are ...

A comprehensive mathematical model for cardiac perfusion [PDF]

arXiv, 2023
We present a novel mathematical model that simulates myocardial blood perfusion by embedding multiscale and multiphysics features. Our model incorporates cardiac electrophysiology, active and passive mechanics, hemodynamics, reduced valve modeling, and a multicompartment Darcy model of perfusion.

Cardiac Organoid Model Inspired Micro‐Robot Smart Patch to Treat Myocardial Infarction

Advanced Materials, EarlyView.
The heart organoid model exhibits the acidic microenvironment characteristic of myocardial infarction, which emerges as a pivotal force propelling the movement of micro‐robots. These micro‐robots, administered through microneedles, can penetrate deep into the tissue, effectively delivering therapeutic payloads to facilitate heart repair.

Evaluation of factors associated with selection for coronary angiography and in‐hospital mortality among patients presenting with out‐of‐hospital cardiac arrest without ST‐segment elevation

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1159-1170, December 1, 2022., 2022
Abstract Background Clinical factors favouring coronary angiography (CA) selection and variables associated with in‐hospital mortality among patients presenting with out‐of‐hospital cardiac arrest (OHCA) without ST‐segment elevation (STE) remain unclear.

AWSnet: An Auto-weighted Supervision Attention Network for Myocardial Scar and Edema Segmentation in Multi-sequence Cardiac Magnetic Resonance Images [PDF]

arXiv, 2022
Multi-sequence cardiac magnetic resonance (CMR) provides essential pathology information (scar and edema) to diagnose myocardial infarction. However, automatic pathology segmentation can be challenging due to the difficulty of effectively exploring the underlying information from the multi-sequence CMR data. This paper aims to tackle the scar and edema
