【摘要】：目的:探究房顫對微創(chuàng)二尖瓣術后患者的靜態(tài)肺功能及運動耐量水平的影響。方法:微創(chuàng)二尖瓣術后患者30例,按有無房顫分為兩組,各15例,兩組間基本情況保持均衡。所有患者在2013年1月1日至2014年9月30日期間進行靜態(tài)肺功能及癥狀限制的極量心肺運動測試。肺功能由用力肺活量、第一秒用力呼氣量、兩者實測值分別占預計值的百分比,及1秒率表示;運動耐量用峰值時公斤攝氧量(peak VO2/kg),表示,通氣效率用無氧閾時二氧化碳通氣當量(VE/VCO2@AT)表示。結果:房顫組表現(xiàn)為輕度限制性肺通氣障礙,而竇律組平均肺通氣功能正常;房顫組運動耐量水平顯著低于竇律組,兩組peak VO2/kg分別為17.34±2.82 ml·kg-1·min-1、20.35±4.13 ml·kg-1·min-(1P=0.03);兩組間VE/VCO2@AT也有顯著性差異(34.48±4.16 vs 29.80±4.51,P0.01)。結論:二尖瓣術后合并房顫的患者,其肺容積及運動耐量明顯低于竇律的患者,運動耐量下降的主要機制為心排血量減少。
[Abstract]:Objective: To study the effects of atrial fibrillation on static pulmonary function and exercise tolerance in patients with level of minimally invasive mitral valve surgery. Methods: 30 cases of patients with minimally invasive mitral valve surgery, according to whether atrial fibrillation were divided into two groups, 15 cases each, two groups basically balanced. Maximal cardiopulmonary exercise test were all static pulmonary function and symptom limited in the period from January 1, 2013 to September 30, 2014. The lung function by FVC, FEV1, respectively. The percentage of predicted value between the measured value, and a second rate; exercise tolerance with peak oxygen uptake (peak kg VO2/kg), said that with the ventilation efficiency of carbon dioxide equivalent ventilation anaerobic threshold (VE/VCO2@AT). Results: AF group showed mild restrictive ventilatory disorder, and sinus rhythm group average normal pulmonary ventilation function; atrial fibrillation group exercise tolerance level was significantly lower than that in sinus rhythm group, two groups of peak VO2/kg were 17.3 4 + 2.82 ml kg-1 + 4.13 min-1,20.35 ml kg-1 min- (1P=0.03); VE/VCO2@AT in the two groups had significant difference (34.48 + 4.16 vs 29.80 + 4.51, P0.01). Conclusion: atrial fibrillation and mitral valve surgery patients, the lung volume and exercise tolerance was significantly lower than that of patients with sinus rhythm the main mechanism of exercise tolerance, decreased cardiac output is reduced.

【正文快照】： 微創(chuàng)二尖瓣手術可在小創(chuàng)傷的情況下進行二尖患者一般資料見表1,兩組間年齡、性別、身高、體瓣異常結構的糾正,使得手術創(chuàng)傷對患者的影響減重、體質指數(shù)、術后天數(shù)無顯著性差異。少[1],但是仍有許多患者術后癥狀改善不明顯,伴有1.2方法容易氣促、疲勞及運動能力降低的問題[2]。，
