M e t h o d s Design: Planned subanalysis of a randomized placebo-controlled trial (PCI-Clopidogrel as Adjunctive Reperfusion Therapy [CLARITY]-Thrombolysis in Myocardial Infarction [TIMI] 28 trial [CLARITY-TIMI 28]). Allocation: {Concealed}†.* Blinding: Blinded (clinicians, patients, {data collectors, clinical events committee, and data analysts}†).* Follow-up period: 30 days. Setting: 319 sit...
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 ...
Abstract Background: Cardiovascular disease and coronary disease is at the top of the main causes of death in developed and developing countries. In many studies have been done in recent years, the role of heart rate recovery (HRR) as a predictor of mortality in patients with efficient factor for coronary artery disease (CAD) and vascular involvement are well known. In this research relationshi...
BACKGROUND Recent studies have demonstrated the association between increased concentrations of high-sensitivity cardiac troponin T (hs-cTnT) and the incidence of myocardial infarction, heart failure, and mortality. However, most prognostic studies to date focus on the value of hs-cTnT in the elderly or general population. The value of hs-cTnT in symptomatic patients visiting the outpatient dep...
Introduction: Coronary angiography is the most common angiographic procedure for diagnosis and treatment of the heart diseases. Herein, we aimed to evaluate the entrance surface dose (ESD), dose area product (DAP), as well as cancer risk in interventional cardiology procedures. Materials and Methods: This study was conducted during July-December 2015 at Shahid Madani Heart Center in Khorramabad...
Background & Aims:Over the last decade, cardiovascular disease (CVD) has become the single largest cause of death worldwide including all developing regions. The coronary artery disease (CAD) is the most lethal form of CVD. Ceruloplasmin is a ferroxidase enzyme with two paradoxically oxidative and antioxidative performances. Some studies show that ceruloplasmin give rise to atherosclerosis...
This study was conducted on a human anthropomorphic phantom to investigate the effective dose and entrance skin dose (ESD) in selected radiosensitive organs through invasive and computed tomography (CT) coronary angiography procedures using different dose-saving techniques. The effective dose was calculated as 2.49, 3.35 and 9.62 mSv, respectively, corresponding to three coronary CT angiography...
OBJECTIVES To determine if coronary computed tomographic angiography enhances prediction of perioperative risk in patients before non-cardiac surgery and to assess the preoperative coronary anatomy in patients who experience a myocardial infarction after non-cardiac surgery. DESIGN Prospective cohort study. SETTING 12 centers in eight countries. PARTICIPANTS 955 patients with, or at risk ...
Introduction: Coronary angiography is a common procedure in diagnostic and treatment of cardiac heart disease. After angiography, the patient remains on bed rest for at least a further 6-24 hours in order to reduce the complications at the groin site. Due to this enforced supine position bed rest and immobilization, patients frequently experienced low back pain. The present study aimed to deter...
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...
