Introduction: Coronary angiography is a Diagnostic-Therapeutic method involving ionizing radiation. This method causes to DNA damage with form double stranded breaks which is followed by the phosphorylation of the histone, H2AX. H2AX is a key factor in the repair process of damaged DNA which will accumulate to damage sites. In human cells, H2AX constitutes about 10% of the H2A ...

background: coronary angiography is recognized as the gold test for diagnosis of coronary artery diseases. based on the literature review, little is known about patients’ expectations about this procedure. understanding the patient’s expectations is an important way to achieve patient‑centered care. the purpose of this study was to explore the expectations of iranian patients undergoing coronar...

background: coronary angiography is frequently applied for diagnostic purposes in patients with coronary artery disease. be that as it may, there is still no consensus about the optimal time for the ambulation of patients following femoral arterial puncture. we sought to compare 6 hours of complete bed rest and 2 hours of complete bed rest in patients after angiography. methods: this randomized...

background: atherosclerotic renal artery stenosis (aras) remains underdiagnosed due to its nonspecific demonstrations. we aimed to both estimate the frequency of aras in high-risk non-selected patients undergoing simultaneous coronary and renal catheterization and possibly identify a predictive model for aras using baseline clinical, laboratory, and coronary angiographic variables. methods: the...

results prediction of the rca as culprit lesion using tierala's algorithm was 86% sensitive and 50% specific. prediction of lcx occlusion based on st-elevation ≥ 1 mm in v6 was 87% specific (p = 0.005). sum of st elevation in leads v5 and v6 more than 2.5 mm, was a good marker of lcx prediction (p = 0.044). st-elevation in v4r was 48% sensitive and 89% specific for rca prediction (p = 0.004). w...

the use of noninvasive assessment tools such as multi-slice ct coronary angiography (msct-ca-ca) is recently considered mainly because it offers safety, patient convenience, and faster performance. the aim of the present study was to determine the ability of msct-ca-ca for the detection of significant stenoses in the coronary arteries, in comparison to conventional invasive coronary angiography...

this study evaluated the relationship between the location of the most severe coronary artery stenosis and the subsequent acute myocardial infarction (ami). methods: of 1590 patients who were admitted with a diagnosis of ami, we identified 44 patients who had undergone previous myocardial perfusion spect. thirty-one of these patients also had previous coronary angiography. the relationship betw...
