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...

Background Coronary Artery Disease-Reporting and Data System (CAD-RADS) standardises Computed Tomography Angiography (CTCA) reporting. calcification can overestimate stenosis. We hypothesized where CAD-RADS category is assigned due to predominantly calcified maximal stenosis (Ca+), the CTCA-derived Fractional Flow Reserve (FFRCT) would be lower compared non-calcified stenoses (Ca-) of ...

Noninvasive coronary imaging is often considered the Holy Grail among cardiologists and radiologists interested in the diagnosis and treatment of coronary atherosclerosis.1–3 That noninvasive coronary imaging would aid in establishing new prevention and treatment strategies in a wide range of clinical scenarios, ranging from early subclinical diagnosis of atherosclerosis in asymptomatic individ...

Introduction:Gated myocardial perfusion SPECT has diagnostic and prognostic values in coronary artery disease (CAD). We tried to determine prognostic values of the left ventricular perfusion & functional indices as well as transient left ventricular dilation (TID) derived from gated myocardial perfusion SPECT. Methods: 1820patients who underwent gated myo...

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...

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...

x-ray coronary angiography has been a gold standard in the clinical diagnosis and interventional treatment of coronary arterialdiseases for decades. in angiography, a sequence of images is obtained, a few of which are suitable for physician inspection. thispaper proposes an automatic algorithm for the extraction of one or more frames from an angiogram sequence, which is most suitablefor diagnos...
