INTRODUCTION: Angiopoietin-2 (Ang-2) plays a critical role in inducing tumor cell infiltration, and this invasive phenotype is caused by up-regulation of matrix metalloproteinase (MMP)-2. The relationship between Ang-2 and MMP-2 in atherosclerosis has not been reported yet. The aim is to measure the plasma concentrations of Ang-1, Ang-2 and MMP-2 and assess the correlation between the concentrations of these factors in coronary heart disease (CHD) patients. MATERIAL AND METHODS: The testing was done in a cross-sectional study...

We report the imaging findings of an uncommon coronary vascular termination anomaly, with fistula to the pulmonary artery. This 70 year old female patient presented unstable angina, showing a coronary artery fistula depicted in coronary angiogram from the left coronary to the pulmonary artery, with no significant atherosclerotic pathology. Due to development of ventricular tachycardia in stress echocardiogram examination, she was proposed for coronary fistula closure. Coronary CT was performed for procedure planning and allowed the identification of a second unsuspected fistula from the right coronary to the right pulmonary artery...

Little is known about the significance of asymptomatic intra-cranial lesions (ICL) identified by brain MRI in coronary artery disease (CAD) patients. Silent cerebral lesions are suggested to be associated with arterial stiffness in healthy subjects. We investigated whether subclinical ICL are associated with arterial stiffness and the prognosis in CAD patients without medical history of cerebrovascular diseases. We recruited CAD patients who required percutaneous coronary intervention (PCI), did not meet exclusion criteria, and agreed with MRI before PCI...

A 39-year-old man exhibiting unstable angina was admitted to our hospital, and urgent coronary angiography revealed stenosis of the proximal left anterior descending coronary artery (LAD). A drug eluting stent was implanted at this site, and the patient was discharged uneventfully on the 3rd hospital day. Optical frequency-domain imaging (OFDI) was successful in detecting an intra-plaque hematoma, minor intimal disruption, and thrombus at the culprit lesion in this patient. These observations suggest that this hematoma might be the result of subsequent blood filling into the ruptured plaque through this minor intimal disruption...
