BACKGROUND Patients with coronary artery disease can accumulate significant radiation dose through repeated exposures to coronary computed tomographic angiography, myocardial perfusion imaging with single photon emission computed tomography or positron emission tomography, and to invasive coronary angiography. Aim of the study was to audit radiation doses of coronary computed tomographic angiog...

Background and Objective: Coronary artery disease (CAD) is one of the most common diseases today. Among the diagnostic methods, angiography is the main and gold standard in the diagnosis Since angiography is an invasive procedure, this procedure complications range widely from minor problems with short term sequelae to life threatening ones may cause irreversible damage or even death. Materials...

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...

Ejection fraction is the most important indicator of heart failure. Angiography , is a standard method to demonstrate ejection fraction but it is invasive. Therefore determination of sensitivity and specificity of echocardiography versus angiography is a good guidance for physicians. A total number of 50 patients were enrolled in a prospective study. Two dimension and M-Mode echocardiography...

Since the first serendipitous selective coronary angiography was performed by pediatric cardiologist Dr. Mason Sones in 1958 during ventriculography and aortography (Sones et al., 1959), invasive coronary angiography has become well established as the diagnostic gold standard for coronary artery disease. Coronary angiography provides definitive information of “luminology” (radiographic outline ...

BACKGROUND Multi-slice computed tomography (MSCT) is a fast-growing technology that permits a non-invasive, yet reliable, assessment of coronary atherosclerosis. We sought to explore the diagnostic accuracy of MSCT angiography in the detection of significant stenosis of the left main coronary artery (LMCA) in a series of patients with an intermediate pre-test likelihood of coronary artery disea...

SCIENTIFIC BACKGROUND Various diagnostic tests including conventional invasive coronary angiography and non-invasive computed tomography (CT) coronary angiography are used in the diagnosis of coronary heart disease (CHD). RESEARCH QUESTIONS The present report aims to evaluate the clinical efficacy, diagnostic accuracy, prognostic value cost-effectiveness as well as the ethical, social and leg...
