背景：在进行透析的患者中，常见的是主动脉瓣钙化和主动脉狭窄。然而，主动脉狭窄的进展速度仍然不清楚。方法：总共对55名接受透析的患者进行了超声心动图随访，为期12个月。结果：钙化组与非钙化组比较，主动脉瓣最大血流速度进展率和主动脉瓣面积下降率分别为0.37±0.36m/S和0.17±0.29m/S，P=0.027；0.17±0.15 cm(2)和0.04±0.07 cm(2)，P
Background: In patients undergoing dialysis, aortic valve calcification and aortic stenosis are frequently found. However, the rate of progression of aortic stenosis is still unclear.Methods: In all, 55 consecutive patients undergoing dialysis were followed up by echocardiography for a period of 12 months. Patients were divided into two groups: noncalcification (no or mildly calcified aortic valve) and calcification (moderate or heavily calcified aortic valve).Results: The rate of progression of maximum aortic jet velocity and degression of aortic valve area were more rapid in calcification group than in noncalcification group (0.37 +/- 0.36 m/s and 0.17 +/- 0.29 m/s, P =.027; 0.17 +/- 0.15 cm(2) and 0.04 +/- 0.07 cm(2), P
