Echocardiographic measurements of left atrial volume (LAV) were evaluated in 57 consecutive patients with ischaemic heart disease. LAV was 38 ml/m (SD 11), larger in patients with ejection fraction (EF) below 45% than in patients with normal EF (≥55%) but in regression analyses only E/e' correlated independently with LAV. Measurements of LAV had acceptable reproducibility where repeated examinations indicated that half of the variability was explained by the measurement procedure.

The aim of this methodological study was to increase the usefulness of TBP by exploring the interchangeability between TBP from the first and second toe and by investigating daily routine reproducibility and measurement variability. According to our study design pressure values were based on three measurements that were averaged.

Flow velocity measurement by duplex ultrasonography (DUS) is widely accepted as a preoperative method for grading carotid stenoses. Diameter-based grading is used for angiographic methods, but so far the experience is limited regarding diameter-based grading using DUS. In 101 cases with different degrees of carotid stenoses, we compared diameter- and velocity-based grading using DUS and evaluated variability and reproducibility for diameter measurements in 38 of the stenoses.

The aim of this study was to compare obstruction and collateralization as seen with magnetic resonance venography with variables of venous occlusion plethysmography in patients with postthrombotic syndrome. Methods Medical records, magnetic resonance venography and venous occlusion plethysmography data were analyzed in 28 patients (33 legs).
View Article and Find Full Text PDFBackground: Our aims were to describe macro- and microvascular disease by the use of a combination of toe blood pressure (TBP) and transcutaneous oxygen pressure (TcPO2) measurements, and through this approach we aimed to classify lower limb ulcers. One specific aim was to evaluate whether patients with diabetes had a more pronounced disturbance of the microcirculation compared to patients without known diabetes.
Methods: The study included a series of 498 patients with suspected critical lower limb ischemia.
