The effects of coronary pressure on coronary stenosis resistance were studied in 13 open-chest dogs. A noncircumferential stenosis was produced in the circumflex coronary artery by placing sutures into either side of the artery and invaginating a portion of the arterial wall by tying the sutures. Coronary pressure both proximal and distal to the stenosis and coronary flow were measured. Coronar...

BACKGROUND Coronary artery disease (CAD) is associated with the numbers of risk factors causing coronary atherosclerosis. Coronary artery stenosis is mostly caused by coronary atherosclerosis. OBJECTIVE This study aims to analyze the association between coronary artery stenosis and cardiovascular risk factors. METHODS An observational study was conducted among CAD patients. The diagnostic c...

AIMS To investigate the clinical predictors of coronary atherosclerosis and to assess the utility of maximum-IMT for predicting coronary atherosclerosis in asymptomatic type 2 diabetic patients. METHODS One hundred one Japanese patients with type 2 diabetes underwent computed tomography coronary angiography. Definitions of coronary artery stenosis and vulnerable coronary plaque were luminal n...

PURPOSE To evaluate the diagnostic performance of left coronary bifurcation angles and plaque characteristics for prediction of coronary stenosis by dual-source CT. METHODS 106 patients suspected of coronary artery disease undergoing both coronary computed tomography angiography (CCTA) and invasive coronary angiography (CAG) within three months were included. Left coronary bifurcation angles ...

Background: Pulse pressure has recently been considered as a predictor of coronary heart disease. The difference between systolic and diastolic blood pressure is called pulse pressure. Various factors including increased age, vascular stiffness, stenosis, and hypertension are associated with pulse pressure. The present study, therefore, aimed to investigate the relationship between some cardiov...

background: the incidence of stroke is 2.1-5.2% in bypass surgery patients with a mortality of 0-38%. this study was designed to evaluate the incidence of significant carotid artery stenosis and its related risk factors in candidates for coronary artery bypass graft (cabg) surgery. methods: 1045 consecutive candidates for cabg underwent carotid artery doppler examination in a prospective study....

impaired fasting glucose identifies individuals at high risk of progression to diabetes but the role of ifg as a coronary artery disease risk factor, independent of its progression to diabetes and its association with other coronary artery disease risk factors ,is unclear. a cross-sectional study was conducted to evaluate the hypothesis that impaired fasting glucose increased the likelihood of ...

 Introduction: Prevalence of stroke following coronary artery bypass graft surgery (CABG) is % 2.1-5.2 and associated with high mortality. The purpose of this study was to investigate the prevalence of carotid artery disease in patients undergoing CABG surgery.  Methods: This cross-sectional study was performed in the years 2010-2011 on 192 patients who underwent open heart surgery (CABG) in...
