objectives to evaluate predictive value of vessel specific coronary artery calcium (cac) score in predicting obstructive coronary artery disease. patients and methods in this diagnostic test study we evaluated patients with coronary computed tomography angiography (ccta) and cac score which had been referred to two referral radiology center in tehran, iran and finally we selected 2525 patients ...

A 55-year-old man presented with clinical signs of an aortic arch aneurysm. Angiography, MRI and CT demonstrated an aortic arch aneurysm and an aneurysm of the aberrant right subclavian artery. Coronary angiography revealed 95% stenosis in the right coronary artery. Right common carotid artery-right subclavian artery bypass, arch graft replacement and coronary artery bypass grafting were perfor...

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 ...

Although either coronary artery aneurysm or coronary arterio-venous fistula may be found infrequently during coronary angiography, it is very rare to see combination of both structures. Here we present a case of coronary artery fistula combined with a large aneurysm. The aneurysm resembled a mass just beside the left heart border in the chest X-ray (CXR) film. The patient came to our hospital f...

introduction: during the angiography of coronary vessels a great amount of  iodine mixed with radio-contrasts enter the body, and if autonomic centers exist in thyroid it causes hyperthyroidism. this can be dangerous in patients with cronary artery disease (cad). this study aimed to determine the effect of a radio-contrast used in coronary angiohraphy on thyroid’s function in patients referring...

background: paraoxonase-1(pon1), a high-density lipoprotein (hdl) associated enzyme, is believed to contribute in the patho­genesis of coronary artery disease (cad). the aim of this study was to evaluate the association of pon1 promoter c (-107)t polymorphism with the extent of coronary artery stenosis in iranian patients. methods : the rflp analysis for determination of the c(-107)t genotype d...

A 50-year-old man was referred to our hospital because of persistent atypical chest pain. His past medical history was remarkable for a non ST elevation myocardial infarction, treated five months previously with PCI on the right coronary artery. Two months later, for chest pain, he underwent coronary angiography that showed a right coronary artery with slight ectasia near the stent. Five months...

A 74-year-old man with a history of high blood pressure, smoking, and cerebrovascular accident 6 months ago was admitted to our center for chest pain radiating to back. The blood pressure was 140/95 mmHg and pulse was 88/minute. Physical examination revealed an apical systolic murmur. Laboratory tests including evidence of Behcet disease, connective tissue disease, or autoimmune form of vasculi...

Coronary artery aneurysms, characterized by abnormal dilatations of a localized portion of the coronary artery, are an uncommon finding during angiography. We present a case where a giant right coronary aneurysm was detected during angiography, in a patient admitted with a inferior wall myocardial infarction.
