心肺运动试验(cardiopulmonary exercise testing,CPET)是在一定负荷下测出摄氧量和二氧化碳排出量等代谢、通气指标及心电图变化,反映细胞呼吸功能的变化[1]。1975年呼吸疾病学者Wasserman提出:单独给心脏或肺脏增加负荷是不可能的,所有的运动均需要心肺的协调,以及周围循环与 相似文献

许多心肺疾病在静息状态下往往处于代偿状态,在运动状态下才会出现一系列病理生理学改变。目前临床广泛应用的彩色超声、肺功能仪、心电图、冠状动脉造影等方法多数只能反映静态下心肺及血管功能情况,易导致疾病诊断、治疗延误。心肺运动试验是通过检测人体静息和运动状态时氧和二氧化碳变化趋势分析心肺协调性及功能状态的一种方法,其理论基础是气体交换。 相似文献

Gastroesophageal reflux disease (GERD) has been associated with a variety of pulmonary manifestations, but it is unclear if gastroesophageal reflux causes any abnormality in pulmonary function. Cardiopulmonary exercise test (CPET) is a specialized method that is used to evaluate respiratory function during exercise. The aim of this study was to reveal any abnormality of pulmonary function in patients with GERD and respiratory symptoms. We evaluated 34 patients with GERD (24 men and 10 women, aged 21–63) and extraesophageal respiratory symptoms (wheezing and/or cough) before therapy and after a 12‐week treatment with double dose of omeprazole. No patient presented abnormal spirometry. CPET was performed in all the patients at baseline and after completion of the 12‐week treatment. CPET parameters including VO2rest, VO2max, VCO2rest, VCO2max, O2–puls rest, O2–puls max, HR (heart rate) rest, HRmax, PETCO2rest, PETCO2max, and VE/VCO2 slope were recorded pretreatment and posttreatment. Twenty‐four patients (70.6%) had esophagitis (grade A–D), 16 patients had hiatal hernia (47.1%), and 13 patients (38.2%) tested positive for Helicobacter pylori. All of the patients completed the CPET. No one presented shortness of breath or respiratory symptoms. CPET parameters were within normal limits in all of the patients. Twenty‐eight patients were reevaluated. No improvement in any CPET parameter posttreatment was observed despite remission of esophageal and extraesophageal respiratory symptoms in all patients. No statistically significant difference was observed pretreatment and posttreatment between the patients older and younger than 40 years, smokers and nonsmokers, Hp(+) and Hp(–) patients, and those with and without hiatal hernia and esophagitis. The patients with GERD and respiratory manifestations and normal spirometry present no pulmonary dysfunction during CPET. No alterations in CPET values posttreatment or differences in CPET values according to age, smoking, Hp status, presence of esophagitis, or hiatal hernia were observed. 相似文献

BackgroundCoronary angiography (CAG) is “gold standard” for the diagnosis of coronary heart disease (CHD). This study aimed to explore the diagnostic value of cardiopulmonary exercise testing (CPET) and the oxygen uptake kinetics indexes of CPET.MethodsOne hundred thirty-one patients with chest pain who underwent coronary angiography in the Department of Cardiology of our hospital from April to September 2021 were selected. According to the results of angiography, the patients were divided into an observation group (patients with coronary heart disease, n=80) and a control group (patients without coronary heart disease, n=75). Both groups underwent CPET before angiography. The differences of peak oxygen uptake, anaerobic threshold, peak kilogram oxygen uptake, peak oxygen pulse, maximum exercise load, maximum metabolic equivalent, and exercise time between the two groups were compared. Also, the correlation between the above indexes and the degree of coronary artery stenosis was analyzed, and the clinical value of the CPET in the diagnosis of CHD was evaluated.ResultsThe peak oxygen uptake, anaerobic threshold, peak kilogram oxygen uptake, peak oxygen pulse, maximum exercise load, maximum metabolic equivalent, and exercise time in the observation group were lower than those in the control group (P<0.01), and were negatively correlated with the Gensini score (P<0.01). The area under the receiver operating characteristic (ROC) curve of the above seven indexes in the combined diagnosis of CHD was 0.974, the sensitivity was 86.40%, and the specificity was 98.50%, which was better than the clinical value of any of the above indexes alone.ConclusionsCPET is an effective non-invasive examination in the diagnosis of CHD, and has a certain clinical value in the evaluation of the severity of coronary artery stenosis. 相似文献

Variables derived from the cardiopulmonary exercise test (CPX) provide objective information regarding the exercise capacity of children with cerebral palsy (CP), which can be used as the basis for exercise recommendations. Performing maximal CPX might not be appropriate, safe, or practical for children with CP. In the present study, the safety and feasibility of symptom-limited CPX using the modified Naughton protocol, a submaximal protocol, were investigated in children with CP, Gross Motor Function Classification System (GMFCS) level I or II. The present study included 40 children aged 6 to 12 years with CP who underwent symptom-limited CPX. CPX was performed to measure cardiopulmonary fitness using a treadmill with a modified Naughton protocol. Motor capacity was assessed using the Gross Motor Function Measure (GMFM), Pediatric Balance Scale (PBS), Timed Up and Go (TUG) test, and 6-minute walk test. Thirty-seven children with CP successfully completed testing without any adverse events during or immediately after CPX (dropout rate 7.5%). The reason for test termination was dyspnea (51.4%) or leg fatigue (48.6%). Based on the respiratory exchange ratio (RER), 21 of 37 (56.8%) children chose premature termination. The relationship between the reason for test termination and RER was not statistically significant (Spearman rho = 0.082, P = .631). CPX exercise time was strongly correlated with GMFM (Spearman rho = 0.714) and moderate correlation with PBS (Spearman rho = 0.690) and TUG (Spearman rho = 0.537). Peak oxygen uptake during CPX showed a weak correlation with GMFM and a moderate correlation with PBS. This study revealed that symptom-limited CPX using the modified Naughton protocol was safe and feasible for children with CP and GMFCS level I or II. 相似文献
