coronary heart disease has been one of the main threats of human health. coronary angiography is taken as the “gold standard” for the assessment of coronary artery disease. but sometimes, the images are difficult to interpret visually because of the crossing and overlapping of the vessels in the angiograms. vessel extraction from x-ray angiograms has been a challenging problem for several years...

background: the incidence of stroke after coronary artery bypass grafting (cabg) is between 0.9% and 6.7%, which significantly increases in-hospital and out-hospital costs. this study was designed to evaluate the prevalence of significant carotid stenosis and its risk factors in cabg. methods: in total, 2044 consecutive patients undergoing elective cabg were investigated through a pre-operative...

Heart failure is a clinical syndrome characterized by the inability of the heart to provide nutrient supply to tissues. In 75% of cases, the underlying pathology causing heart failure in patients with cardiac death is coronary heart disease. A rabbit model of heart failure with coronary ligation was produced to mimic coronary heart disease in humans. After producing the model, two arteries ...

The dominant paradigm in the diagnosis of patients with stable coronary artery disease was identification obstructive lesions arteries, and then - ensuring possibility myocardial revascularization. diagnostic algorithms used until recently led to fact that invasive angiography changes arteries were detected less than half cases. In 2019 European Guidelines for Diagnosis Chronic Coronary Syndrom...

Coronary artery originating from pulmonary is a rare congenital vascular malformation, which generally presents corresponding clinical symptoms with the growth of patients’ age. CTA and angiography are important methods for diagnosis this disease, provide evidence treatment strategies patients. Keywords: bicardiovascular malformations; coronary arteries; cta.

background: whether coronary artery ectasia (cae) is a unique clinical finding or results from other clinical entities is still unknown. we aimed to determine the cae prevalence, investigate the relationship between cae and patients’ demographic and clinical characteristics, and assess the prognosis at follow-up in a sample of iranian population. methods: t otally, 10057 patients who underwent ...

Highlights . Taking into account the connection between increase in volume of myocardial adipose tissue and vessels with massive calcification coronary arteries heart disease, morphometry epicardial perivascular during routine tomographic examinations can be considered as a non-invasive technique for determining surrogate marker severe lesion. Aim To evaluate relationship artery (CA) morphometr...

BACKGROUND AND PURPOSE The purpose of this study was to determine whether significant atherosclerotic disease in the carotid arteries predicts significant atherosclerotic disease in the coronary arteries, vertebral arteries, or aorta in patients with symptoms of acute ischemic stroke. METHODS Atherosclerotic disease was imaged using CT angiography in a prospective study of 120 consecutive pat...
