LA MK-1775 stiffness was significantly related with LA volume indices and reservoir function. Noninvasively measured LA stiffness is expected to be used for the assessment of LA function in patients, but the role

of LA stiffness in the progression of AF was remained to be proven. Acknowledgements This study was supported by an Industry-Academy grant of Korean Society of Echocardiography (2008, Cho GY).
All subjects underwent abdominal and carotid US in order to assess hepatic steatosis Inhibitors,research,lifescience,medical and carotid IMT measurement or analysis for the presence of plaques. We used Accuson Sequoia (Siemens, Mountain View, CA, USA), with convex probes (2.5-5 MHz) to scan the liver, and Vivid 7 (GE Medical System, Milwaukee, WI, USA) equipped with a 7 to 12-Mhz linear-array scanner, with a limit of detection of < 0.1 mm to scan carotid arteries. All investigations were performed by two experienced operators (for abdominal and carotid US), blinded to each other regarding the respective US measurements and unaware Inhibitors,research,lifescience,medical of patients' clinical data. Following the American gastroenterological association classification of NAFLD,18) NAFLD was defined as the presence of diffuse hyperechoic echo-texture, bright liver,19) increased liver echo-texture compared

Inhibitors,research,lifescience,medical with the kidneys, vascular blurring and deep attenuation of the ultrasonic beam. For carotid US, all subjects were examined in a supine position, neck extended, Inhibitors,research,lifescience,medical and the chin facing the counter lateral side. Carotid arteries were examined bilaterally in the longitudinal and transversal planes. The common, internal, and external carotid arteries were

examined for evidence of atherosclerotic lesions as seen in thickness of the IMT of the common carotid artery, internal carotid artery and external carotid artery and plaque presence. After placing the region of interests in the far wall of the common carotid artery (CCA), mean IMT was estimated in a region free of atherosclerotic plaques with the use of an automatic tracking system.20) Mean IMT was averaged from mean CCA IMT in both far wall, and maximum IMT Inhibitors,research,lifescience,medical was defined as the thickest IMT regardless of sites. The increased IMT was considered as ≥ 1.0 mm in either or both carotid arteries and the presence of atherosclerotic plaque was defined as localized lesions with protrusion into the arterial lumen or IMT greater than 1.5 mm.21) Carotid stenosis was not included in the analysis, because no subjects had click here severe stenosis (≥ 50%). Statistical analysis Data were expressed as mean values ± standard deviation and frequencies were expressed as percentages. All analyses were performed using a SPSS 13.0 package program (IBM corp., Armonk, NY, USA). Statistical analysis between the groups was performed using student’s t-test for continuous variables and the chi-square test for categorical data. Statistical correlations were determined by the nonparametric Spearman test.
