BACKGROUND AND OBJECTIVES We sought to determine whether an elevated homocysteine (Hcy) level is associated with a worse prognosis in Korean patients with coronary artery disease (CAD). SUBJECTS AND METHODS A total of 5839 patients (60.4% male, mean age 61.3±11.2 years) with CAD were enrolled from 2000 to 2010 at Gangnam Severance Hospital. CAD was diagnosed by invasive coronary angiography. ...
BACKGROUND Earlier trials have shown that a routine invasive strategy improves outcomes in patients with acute coronary syndromes without ST-segment elevation. However, the optimal timing of such intervention remains uncertain. METHODS We randomly assigned 3031 patients with acute coronary syndromes to undergo either routine early intervention (coronary angiography < or = 24 hours after rando...
Background and purpose: Coronary artery disease is a major cause of mortality, morbidity, and disability in society and patients incur high expenditure on treatment. Pulp stones are ectopic calcifications of the pulp vessel walls, so, they can have similar pathogenesis as those of other organs and coronary atherosclerosis. The purpose of this study was to investigate the correlation between cor...
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. Th...
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 & Aim: Lack of knowledge about coronary angiography may cause anxiety and stress in patients. Implementing appropriate educational methods can be effective in decreasing the level of anxiety among these patients. This study aimed to compare the effects of face-to-face with group education on anxiety and knowledge of patients undergoing coronary angiography. Methods & Materials: This...
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...
Introduction: Bleeding, hematoma and cyanosis in the arterial catheter site are considered the most important complications after coronary artery angiography. A method in which homeostasis can result faster and patient can walk sooner should be found. Therefore, this study aimed to compare two methods of sandbags and transparent film dressings to reduce complications after coronary artery angio...
BACKGROUND The joint contribution of sex, ethnicity, and initial clinical presentation to the long-term outcomes of patients undergoing coronary angiography for acute coronary syndrome (ACS) or stable angina, in whom there is angiographic evidence for obstructive coronary artery disease, remains unknown. METHODS AND RESULTS We conducted a population-based cohort study on 49 556 adult ACS or s...
BACKGROUND We investigated the relationship of quantitative plaque features from coronary computed tomography (CT) angiography and coronary vascular dysfunction by impaired myocardial flow reserve (MFR) by (13)N-Ammonia positron emission tomography (PET). METHODS AND RESULTS Fifty-one patients (32 men, 62.4±9.5 years) underwent combined rest-stress (13)N-ammonia PET and CT angiography scans b...
