background and objectives: studies have shown that patients awaiting coronary angiography (ca) are often anxious. high level of anxiety can lead to physical and psychological stress with adverse effects on organs, especially heart. there is limited information on state and trait anxiety level in these patients in the literature. this study was thus designed to investigate the level of these tw...
Background and purpose: Flow-mediated dilatation (FMD) measurement in brachial artery (BA) is a method of assessing endothelial cell function and predicting atherosclerotic coronary artery disease. We investigated the predictive value of FMD for the presence of coronary artery disease (CAD) in a low-risk group of patients. Materials and methods: A prospective study was performed in 397 p...
a 73-year-old woman who had undergone coronary artery bypass grafting for coronary artery stenosis six years ago, presented with right lower extremity claudication. angiography revealed right external artery stenosis. elective external iliac ptca was performed complicated with simultaneous external iliac artery and vein rupture that was an exceedingly rare event. retroperitoneal laparotomy with...
tissue level myocardial perfusion is one of the most important prognostic factors after successful recanalisation of the occluded coronary artery in patients suffering acute st elevation myocardial infarction (stemi). the primary objective of the present study was to examine the relationship between videodensitometric myocardial perfusion parameters as assessed on coronary angiograms directly f...
cardiotoxicity is one of the most important adverse event related to anthracycline therapy and can lead in about 1-5% of cases to the occurrence of heart failure. in a higher percentage of patients treated with these drugs asymptomatic left ventricular dysfunction can occur, so that guidelines recommend a strict clinical and echocardiographic monitoring. however, the occurrence of left ventricu...
conclusion: although timi grade 3 flows trended to be higher in the patients who received early tirofiban in the emergency ward, the difference did not constitute statistical significance and possible benefits, therefore, require further clarification. results: the study population had a mean age of 57.17 ± 10.09 years and included 79.3 % males. timi grade 3 flow was seen in 15 (21.4 %) patient...
background: interventional cardiology procedures such as coronary angiography (ca) and percutaneous transluminal coronary angiography (ptca) has been increased recent years. the purpose of this study was to measurement of effective dose to cardiology staffs who operate near the patient and are exposed to non-uniform radiation field due to patient scattered radiation. materials and methods: this...
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...
Introduction: Coronary angiography (CA) is an interventional diagnostic procedure to assess cardiovascular disease. CA is performed using dedicated fluoroscopic systems equipped with either flat detector or image intensifier. There is an increase in the number of CA annually. Reducing the radiation exposure in the CA is essential, especially due to high fluoroscopy time. In ord...
background and purpose: anxiety is a common problem associated with invasive medical procedures, especially in patients undergoing coronary angiography. as an intensifier at cardiovascular reactions, anxiety poses significant risk to the health of patients undergoing angiography. researchers believe that use of benson’s relaxation technique could reduce anxiety in different patients. this study...
