Natriuretic peptide receptor-C regulates coronary blood flow and prevents myocardial ischemia/reperfusion injury: novel cardioprotective role for endothelium-derived C-type natriuretic peptide [PDF]

, 2004
Background: Ischemia/reperfusion (I/R) injury complicates myocardial infarction and stroke by exacerbating tissue damage and increasing risk of mortality.

Comparison of regional blood flow values measured by radioactive and fluorescent microspheres [PDF]

, 2002
Fluorescent microspheres (FM) have become an attractive alternative to radioactive microspheres (RM) for the measurement of regional blood flow (RBF). The aim of the present study was to investigate the comparability of both methods by measuring RBF with

Ventricular Fibrillation Waveform Changes during Controlled Coronary Perfusion Using Extracorporeal Circulation in a Swine Model. [PDF]

PLoS ONE, 2016
Several characteristics of the ventricular fibrillation (VF) waveform have been found predictive of successful defibrillation and hypothesized to reflect the myocardial energy state.

Protecting the ischemic heart : pharmacological protection against myocardial ischemia in rats in vivo and in vitro [PDF]

, 2004
Today in Switzerland approximately 40% of all deaths are due to cardiovascular diseases. More than half of these are due to ischemic heart disease. Among the fatal consequences of ischemic heart disease are life-threatening arrhythmias and myocardial ...

Impact of intermittent apnea on myocardial tissue oxygenation--a study using oxygenation-sensitive cardiovascular magnetic resonance. [PDF]

PLoS ONE, 2013
BACKGROUND: Carbon dioxide (CO(2)) is a recognized vasodilator of myocardial blood vessels that leads to changes in myocardial oxygenation through the recruitment of the coronary flow reserve.

A study protocol for an observational cohort investigating cardiac transthyretin amyloidosis flow reserve before and after Tafamidis treatment: The AMYTRE study

Frontiers in Medicine, 2022
IntroductionAnginal symptoms and signs of ischemia have been reported in some patients with cardiac transthyretin amyloidosis (ATTR) without obstructive epicardial coronary artery disease (CAD).

Oxygenation-sensitive CMR for assessing vasodilator-induced changes of myocardial oxygenation

Journal of Cardiovascular Magnetic Resonance, 2010
Background As myocardial oxygenation may serve as a marker for ischemia and microvascular dysfunction, it could be clinically useful to have a non-invasive measure of changes in myocardial oxygenation. However, the impact of induced blood flow changes on

A Heart with Multiple Coronaries Anomalies: Myocardial Bridging, Left Dominance and High Takeoff of Ostia-An Autopsy Case [PDF]

Journal of Clinical and Diagnostic Research, 2014
Myocardial bridging is a segment of coronary artery that runs intramurally through the myocardium. Though it is commonly seen in the anterior interventricular artery and less commonly in right coronary artery, it can cause limitation in the blood flow ...

Effect of streptozotocin-induced diabetes on myocardial blood flow reserve assessed by myocardial contrast echocardiography in rats

Cardiovascular Diabetology, 2008
The role of structural and functional abnormalities of small vessels in diabetes cardiomyopathy remains unclear. Myocardial contrast echocardiography allows the quantification of myocardial blood flow at rest and during dipyridamole infusion.
