BACKGROUND: We aimed to establish a completely noninvasive technique to assess coronary artery atherosclerosis in living mice using proximal to middle left coronary artery (LCA) velocity ratio as assessed with color Doppler echocardiography (CDE). METHODS …

OBJECTIVE: Matrix metalloproteinases (MMPs) degrade extracellular matrix proteins and play important roles in development and tissue repair. They have also been shown to have both protective and pathogenic effects in atherosclerosis, and experimental …

For an accurate estimate of volumetric coronary flow reserve (CFR) using Doppler-assessed flow velocity measurement, it is important to take into consideration potential diameter change during coronary hyperemia. Using ultrasound techniques, left coronary …

Total longitudinal displacement (tLoD) of the common carotid artery can be measured using the ultrasound-based velocity vector imaging (VVI) technique. This study aimed to investigate clinical correlates and the possible predictive value of tLoD for …

In the present study, we have developed and demonstrated a coronary artery imaging protocol in rats using transthoracic high-frequency CDE (colour Doppler echocardiography) to investigate the potential direct effects of exercise on CFVR (coronary flow …

In vivo mouse coronary artery circulation is still largely unknown. We demonstrate here in vivo coronary flow velocity profiles in anesthesized mice using a novel high-resolution ultrasound technique. … … Non-invasive imaging of coronary arteries in …

Objectives: This study was undertaken to determine if ticagrelor augments adenosine-induced coronary blood flow and the sensation of dyspnea in human subjects. Background: Ticagrelor is a P2Y12 receptor antagonist that showed superior clinical benefit …

Myocardial ischemia is recognized as an important mechanism increasing the risk for cardiovascular events in both symptomatic and asymptomatic patients. In addition to obstructive coronary diseases, systemic inflammation, macro- and microvascular function …

Non-invasive evaluation of coronary flow reserve with transthoracic Doppler echocardiography predicts the presence of significant stenosis in coronary …

Background/Aims: The PCK rat model of polycystic kidney disease is characterized by the progressive development of renal medullary cysts. Here, we evaluated the suitability of high resolution ultrasonography (HRU) to assess the kidney and cyst volume in …
