Coronary angiography delivers accurate information about the vessel topology and shape, but only limited data concerning the vessel cross-section. Intravascular ultrasound provides detailed information about the cross-sectional shape as well as the composition of vessel wall and plaque, but fails to consider the geometric relationships between adjacent images. In this paper, we present a new ap...

OBJECTIVE Dysfunction of cardiac autonomic nerve system is considered as one of risk factors for coronary atherosclerotic heart disease. Heart rate variability (HRV) has been used to study the correlation between damage of coronary artery and dysfunction of autonomic nervous system. We hypothesize the correlation between damage of coronary artery and dysfunction of autonomic nervous system by H...

Development of the coronary vascular system is an interesting model in developmental biology with major implications for the clinical setting. Although coronary vessel development is a form of vasculogenesis followed by angiogenesis, this system uses several unique developmental processes not observed in the formation of other blood vessels. This review summarizes the literature that describes ...

Beside pulsatile motion of vessel, there are two additional movements of coronary arteries. One is from the pulsatile momentum of coronary artery while dampened by the supporting soft tissues. Another movement is responsible by contracting myocardium throughout the cardiac cycle with part of epicardial artery tethered to myocardium. In this study, four different external boundary conditions of ...

OBJECTIVE To detect differences in potential magnetic resonance imaging biomarkers of coronary remodeling between older hypertensive patients and healthy controls. METHODS AND RESULTS Two-dimensional black-blood coronary wall magnetic resonance imaging and 3-dimensional whole-heart coronary magnetic resonance angiography were performed on 130 participants (65-84 years), including 65 hypertens...

M yocardial infarction is a well recognized but infrequent complication of coronary arteriography. In most cases, it has usually been attributed to coronary artery dissection, dislodgement of an arteriosclerotic plaque, sustained hypotension, thromboembolism or spasm of the vessel.’ Fatal thromboembolism following coronary arteriography has rarely been confirmed by postmortem examination since ...

A 13 year old boy is described with hypereosinophilia associated with Kimura's disease, who showed repeated life threatening syncopal attacks during daily activities or at rest. Coronary arteriography demonstrated small aneurysms with irregular vessel walls of both coronary arteries, and the absence of organic stenotic lesions. Infusion of a minimal dose of ergonovine into the right coronary ar...

background: primary percutaneous coronary intervention (primary pci) is the method of choice in establishing reperfusion in acute myocardial infarction (ami) patients. the aim of this study was to determine the success rate of primary pci in a university medical center in iran with a view to promoting it as a first-line therapy in patients with ami, especially in centers with established cathet...

Coronary vessel development is a crucial part of heart development requiring the interplay of the epicardial, myocardial and endocardial layers of the heart for proper formation. Coronary vascularization is regulated by a host of transcription factors further regulated by chromatin remodeling enzymes, including Histone Deacetylases (HDACs). To investigate the functions of HDACs in coronary vasc...
