Objective(s): Apolipoprotein E genotype (APOE) polymorphism affects lipid levels and coronary artery disease (CAD) risk. The aim of this study was to study the association of the Apolipoprotein E genotypes with coronary artery disease in the Iranian population.   Materials and Methods: The Apolipoprotein E genotype in DNA samples extracted from 66 CAD+ patients and 61 control s...

the anomalous origin of the right coronary artery (rca) as a branch from the left anterior descending artery (lad) is a very rare variation of the single coronary artery anomaly. the anomalous vessel arises from the proximal or midportion of the lad and courses anterior to the pulmonary artery trunk in most instances. in this case report, a 61-year-old woman is introduced who underwent coronary...

background: diagnosis of coronary artery disease (cad) in early stages is vital in decreasing mortality by reducing the risk factors. the aim of this study was to investigate the association between erectile dysfunction (ed) and cad. methods: a total of 200 patients were divided into four groups according to their angiography results: group 1 (g1, n = 59): patients with one-vessel disease (1-vd...

objective(s): apolipoprotein e genotype (apoe) polymorphism affects lipid levels and coronary artery disease (cad) risk. the aim of this study was to study the association of the apolipoprotein e genotypes with coronary artery disease in the iranian population.   materials and methods: the apolipoprotein e genotype in dna samples extracted from 66 cad+ patients and 61 control subjects by restri...

PURPOSE To develop a respiratory motion correction framework to accelerate free-breathing three-dimensional (3D) whole-heart coronary lumen and coronary vessel wall MRI. METHODS We developed a 3D flow-independent approach for vessel wall imaging based on the subtraction of data with and without T2-preparation prepulses acquired interleaved with image navigators. The proposed method corrects b...

BACKGROUND Coronary in-stent restenosis cannot be directly assessed by magnetic resonance angiography (MRA) because of the local signal void of currently used stainless steel stents. The aim of this study was to investigate the potential of a new, dedicated, coronary MR imaging (MRI) stent for artifact-free, coronary MRA and in-stent lumen and vessel wall visualization. METHODS AND RESULTS Fi...

vessel extraction is a critical task in clinical practice. in this paper, we propose a new approach for vessel extraction using an active contour model by defining a novel vesselness‑based term, based on accurate analysis of the vessel structure in the image. to achieve the novel term, a simple and fast directional filter bank is proposed, which does not employ down sampling and resampling used...

cardiovascular diseases are one of the most common diseases that cause a large number of deaths each year. coronary artery disease (cad) is the most common type of these diseases worldwide and is the main reason of heart attacks. thus early diagnosis of cad is very essential and is an important field of medical studies. many methods are used to diagnose cad so far. these methods reduce cost and...

elevated total plasma homocysteine (thcy) levels constitute a risk factor for coronary artery disease (cad). a possible relationship was investigated between admission plasma homocysteine level and the angiographic severity and extension of coronary artery disease in patients with cad. this study looks at the relationship between total plasma homocysteine and severity of coronary artery disease...
