INTRODUCTION AND OBJECTIVES: Multidetector computed tomography (MDCT) has been demonstrated as a feasible alternative to invasive coronary angiography (ICA). However, contradictory results have been reported regarding the effect of coronary artery calcium score (CS) on the diagnostic accuracy of MDCT. Our aim was to assess the agreement of MDCT and ICA and to evaluate the influence of CS on this agreement. METHODS: We enrolled 266 consecutive patients who underwent evaluation with 64-slice MDCT and ICA...

PURPOSE: Hemodialysis patients have extremely increased cardiovascular mortality. The coronary artery calcification score (CACS) in uremic patients receiving hemodialysis reflects the severity of atherosclerotic vascular disease and predicts the cardiovascular events. In cardiac conditions, left atrial (LA) size has a prognostic importance. In this study, relationship between coronary artery calcification and left atrial size was investigated. METHODS: This was a cross-sectional study involving 32 hemodialysis patients (16 females, 16 males; mean age, 52...

Nonalcoholic fatty liver disease may range from simple steatosis to fibrosis and cirrhosis. It is associated with the development of coronary artery calcification and appears to be an independent predictor of future adverse cardiovascular events. As the presence of a fatty liver appears to portray an independent increased risk, it may be beneficial to note this on coronary artery calcium scoring reports. Determination of fatty liver is relatively easy to perform. We discuss the method used by the Multi-Ethnic Study of Atherosclerosis (MESA) study for determination of fatty liver from CT coronary artery calcium scoring acquisitions, which may be implemented in clinical analysis...

BACKGROUND: Multidetector coronary computed tomography angiography (CCTA) is increasingly used for noninvasive imaging of the coronary arteries. Radiation exposure, however, is a potential limitation to a more extensive use of this imaging modality. We aimed to demonstrate that a professional teamwork approach, including a cardiologist and a radiologist in performing CCTA, may allow to obtain best quality exams with very low radiation doses. METHODS: A total of 998 consecutive patients underwent CCTA in accordance with the most recent guidelines...

BACKGROUND: Cartilage oligomeric matrix protein (COMP) is mainly found in the skeletal system and vascular smooth muscle cells. Recent researches showed that it had a protective function on blood vessels and could also inhibit vascular calcification. We investigated the serum COMPs in coronary heart disease (CHD) patients, and the relationship between serum COMP and the calcification of coronary artery. METHODS: A total of 233 consecutive chest pain patients who first underwent coronary angiography followed by multi-slice computed tomography (MSCT) within six months were recruited and divided into two groups according to the coronary angiography luminal diameter narrowing percentages: CHD group (diameter narrowing ≥ 50%, n = 194) and control group (diameter narrowing < 50%, n = 39)...

BACKGROUND: Opening of mitochondrial calcium-activated potassium channels (BKCa) reduces infarct size after myocardial ischemia/reperfusion injury (I/R). It is unknown if targeting BKCa-channels improves cardiac performance in the long-term after I/R. METHODS: Experiments were conducted in compliance with institutional and national guidelines in C57BL/6 mice (n=7-8/group). Animals were randomized into two groups. Preconditioning was induced by intraperitoneal application of NS1619 (NS, 1μg/g bw) 10min before ischemia, control animals (Con) received the vehicle...
