A hybrid of light-field and light-sheet imaging to study myocardial function and intracardiac blood flow during zebrafish development.

open access: yesPLoS Computational Biology, 2021
Biomechanical forces intimately contribute to cardiac morphogenesis. However, volumetric imaging to investigate the cardiac mechanics with high temporal and spatial resolution remains an imaging challenge. We hereby integrated light-field microscopy (LFM)

​Circulating Cytokines in Myocardial Infarction Are Associated With Coronary Blood Flow

open access: yesFrontiers in Immunology, 2022
BackgroundThe level of systemic inflammation correlates with the severity of the clinical course of acute myocardial infarction (AMI). It has been shown that circulating cytokines and endothelial dysfunction play an important role in the process of clot ...

Effect of propranolol on regional myocardial function in anesthetized open-chest dogs with myocardial ischemia [PDF]

open access: yes, 1978
Effects of propranolol on ischemic segmental function were studied in anesthetized open-chest dogs. Two segment-length gauges were used for measuring the regional myocardial function: one was sutured on to the left ventricular surface perfused by the ...

Modern scintigraphic methods for assessing myocardial blood flow and reserve

open access: yesБюллетень сибирской медицины, 2021
Background. Today, myocardial perfusion scintigraphy is an informative and accessible method for evaluating ischemic changes in the heart. However, this method has limitations, which are more connected with a semiquantitative assessment of the study ...

Ketone Body Infusion With 3‐Hydroxybutyrate Reduces Myocardial Glucose Uptake and Increases Blood Flow in Humans: A Positron Emission Tomography Study

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
Background High levels of ketone bodies are associated with improved survival as observed with regular exercise, caloric restriction, and—most recently—treatment with sodium–glucose linked transporter 2 inhibitor antidiabetic drugs.
