Pericardial effusion can develop from any pericardial disease, including pericarditis and several systemic disorders, such as malignancies, pulmonary tuberculosis, chronic renal failure, thyroid diseases, and autoimmune diseases. The causes of large pericardial effusion requiring invasive pericardiocentesis may vary according to the time, country, and(More)
BACKGROUND AND OBJECTIVES The purpose of this study was to assess the value of C-type natriuretic peptide (CNP) as a surrogate marker for detection of coronary artery spasm in variant angina pectoris (VAP). SUBJECTS AND METHODS Sixty-six patients (mean age: 51±11 years, M : F=40 : 26) who underwent coronary angiography on suspicion of angina and who were(More)
Stress-induced cardiomyopathy is a unique reversible cardiovascular disease precipitated by acute emotional or physical stress. It is associated with a high prevalence of chronic anxiety disorder that precedes the onset of cardiomyopathy, as well as comorbid cardiovascular risk factors that are similar to the ST segment elevation of myocardial infarction. A(More)
BACKGROUND AND OBJECTIVES It is widely known that both bone loss and vascular calcification are age-related processes. The purpose of this study was to investigate the relationship between coronary artery calcium (CAC) score or bone mineral density (BMD) with age and whether there is a gender difference factoring in the two conditions among healthy(More)
BACKGROUND Although it is known that coronary computed tomographic angiography (CCTA) offers highly negative predictive value to exclude obstructive coronary lesions, the plaque pattern on CCTA has not been fully understood. The purpose of this study was to explore the difference of the plaque patterns on CCTA and to assess the cardiovascular risks in(More)
BACKGROUND The purpose of this study was to compare the value and evaluate the validity of non-invasive methods for the detection of vascular stiffness in never-treated individuals with metabolic syndrome (MetS). METHODS A total of 59 subjects (mean age, 60 ± 12 years; male:female = 35:24) were enrolled in the study and were categorized into the positive(More)
Congenital extrahepatic portocaval shunt (CEPS) is a rare anomaly of the mesenteric vasculature in which the intestinal and splenic venous drainage bypasses the liver and drains directly into the inferior vena cava, the left hepatic vein or the left renal vein. This uncommon disease is frequently associated with other malformations and mainly affects(More)
This study was performed to compare clinical and imaging parameters and prognosis of unprovoked pulmonary embolism (PE), provoked PE with reversible risk factors (provoked-rRF), and provoked PE with irreversible risk factors (provoked-iRF) in Koreans. Three hundred consecutive patients (mean age, 63.6 ± 15.0 yr; 42.8% male) diagnosed with acute PE were(More)
BACKGROUND Non-dippers were reported as showing different left atrial function, compared to dippers, but no study to date investigated the changes in the left atrial function according to the diurnal blood pressure pattern, using tissue Doppler and strain imaging. METHODS Forty never treated hypertensive patients between 30 and 80 years of age were(More)
