Aim. To evaluate the diagnostic accuracy of exercise stress echocardiography on a horizontal cycle ergometer for detection obstructive coronary artery disease (CAD) in patients with low-risk non-ST-elevation acute syndrome (NSTE-ACS). Material and methods . The study included 95 aged 53 (46;63) years (men, 58%), hospitalized regional vascular center NSTE-ACS. Patients known CAD, impaired restin...
OBJECTIVES Maximal graft flow acceleration (max df/dt) determined by transit-time flowmetry (TTFM) in the diastolic phase was assessed as a possible predictor of graft failure in coronary artery bypass patients. METHODS Max df/dt was retrospectively measured in 57 in situ left internal thoracic artery grafts. TTFM data were fitted to a 5-polynomial curve, which was derived from the first-deri...
Abstract Background: Coronary artery disease, (CAD) is an important risk for morbidity and mortality. Because of controversial reports about relation between high-sensitivity C-reactive protein (hs-CRP) level and the severity of coronary artery stenosis, this study was done in Taleghani Hospital. Methods: In this case-control study 85 patients with CAD undergoing coronary angiography were ...
UNLABELLED Little data are available to compare the clinical implications of coronary angiography (CAG) or myocardial perfusion imaging (MPI) as an initial evaluation for stable coronary artery disease (CAD). METHODS From national health insurance claims data in South Korea, patients aged 18 y or older without a known history of CAD, who underwent CAG or MPI for the diagnosis of stable CAD be...
OBJECTIVE Chronic obstructive pulmonary disease (COPD) is a risk factor for cardiovascular disease (CVD). Carotid intima-media thickness (CIMT) is the sign of subclinical atherosclerosis. Therefore, the aim of this study was to evaluate whether CIMT measurement is related with significant coronary artery disease (CAD) in patients with COPD, similar to those without COPD. METHODS One hundred a...
We report a patient who developed subarachnoid hemorrhage (SAH) just after coronary angiography (CAG) with non-ionic contrast media (CM) and minimal dose of heparin. The 55-year-old man had a history of acute ST elevation myocardial infarction that had been treated with primary percutaneous coronary intervention and was admitted for a follow-up CAG. The CAG was performed by the transradial appr...
Background It is widely believed that ST-elevated myocardial infarction (STEMI) generally occurs at the site of mild to moderate coronary stenosis. The aim of this study was to determine the degree of stenosis of infarct-related artery (IRA) in STEMI patients who underwent coronary angiography (CAG) after successful reperfusion with thrombolytic therapy (TT). Methods A total of 463 consecutiv...
PURPOSE The purpose of this study was to investigate the utility incremental diagnostic value of combined assessment with coronary CT angiography (CCTA) and myocardial CT perfusion imaging (CTP) using dual-energy technology with an Adenosine Triphosphate (ATP) load technique. MATERIALS AND METHODS Twenty-one patients underwent ATP-provocation dual-energy CT and CAG. We compared the diagnostic...
A60-year-old man, 4 years after an anterior myocardial infarction at the middle segment of the left anterior descending coronary artery (LAD), underwent coronary angiography (CAG) because of severe continuous chest pain for .3 hours 3 weeks earlier. CAG revealed no significant stenosis but showed a wall fissure with a double-contrast opacification at the proximal segment of the LAD (short arrow...
To characterize the association between chronic kidney disease (CKD), mortality, severity of coronary artery disease (CAD), treatment modality of CAD, and type of coronary stents among patients undergoing coronary angiography (CAG), we retrospectively reviewed the electronic medical records of the patients who underwent CAG at Seoul National University Bundang Hospital in Korea between May 2003...
