background: the effects of opium dependence on prognosis and short term outcome of patients with acute myocardial infarction (ami) are not clear yet. methods: from march 2004 to august 2004 all male patients admitted with diagnosis of ami were enrolled. patients who fulfilled dsm- iv-tr criteria were chosen as opium dependent patients (odp). demographic data, risk factors, peak enzyme levels, l...

purpose: to evaluate the agreement between a new method for quantitative analysis of fundus or angiographic images using photoshop software and clinical judgment. methods: four hundred eighteen fundus and angiographic images of diabetic patients were evaluated by three retina specialists and then by computer using photoshop 7.0 software. four variables were selected for comparison: amount of ha...

abstract objective: to compare the conventional angiographic findings in extremity trauma patients with or without runoff. methods: this was cross-sectional study including all the patients with extremity trauma who underwent conventional angiography during the 2 year period from 2011 to 2013 in angiography departments of mashhad university of medical sciences. mechanism of trauma, type of inju...

background: serum n-terminal pro-brain natriuretic peptide (nt-probnp), a polypeptide secreted by ventricular myocytes in response to stretch, was suggested as a predictor of adverse prognosis of the acute coronary syndrome (acs). we examined the association between nt-probnp level and angiographic findings in acs patients to determine whether it could be used as a predictor of the severity of ...

Potential mechanisms of perilipin 2 in angiographic no-reflow = coronary no reflow.

Angiographic catheters and Guiding play an important role in percutaneous coronary intervention. The structure performance of the catheter determine whether contrast agent can be successfully injected into target vessel, thus providing a preliminary basis for diagnosis disease. provides access related devices determines intervention carried out smoothly. angiographic guiding are described detai...

The wavelet-domain Hidden Markov Tree Model can properly describe the dependence and correlation of fundus angiographic images' wavelet coefficients among scales. Based on the construction of the fundus angiographic images Hidden Markov Tree Models and Gaussian Mixture Models, this paper applied expectation-maximum algorithm to estimate the wavelet coefficients of original fundus angiographic i...

BACKGROUND AND PURPOSE Computerized methods have been introduced for more objective quantification of angiographic occlusion rate and coil density as parameters of successful embolization. This study aimed 1) to evaluate this new computerized method for angiographic occlusion rating and coil density calculations by comparison with corresponding histometric parameters from retrieved human aneury...

Coronary artery connection abnormalities are rare with an angiographic prevalence of approximately 1%. Their symptomatology is very varied, from incidental discovery to sudden death by myocardial ischemia, especially during exercise, hence the importance early diagnosis and management. Angiographic generally easy, but it sometimes difficult specify initial course ectopic vessel, interest non-in...

purpose : to offer a semi-automatic algorithm to determine the area of angiographic hyperfluorescence methods : the proposed algorithm included wavelet filter, histogram equalization and modified otsu thresholding. hyperfluorescent area of 30 angiographic images obtained from patients with leaking choroidal neovascularization (cnv) and diabetic retinopathy were evaluated and the results were co...
