Cardiopulmonary Endurance of Hospitalized Older Adults With Chronic Obstructive Pulmonary Disease

Abstract

Background Chronic obstructive pulmonary disease (COPD) could lead to poor cardiopulmonary endurance, which affects quality of life and increases the risk of rehospitalization or mortality. However, studies investigating associated factors of cardiopulmonary endurance for COPD inpatients are scant. Objective The aim of the study was to investigate whether and how age, gender, COPD severity, body composition, dyspnea, respiratory muscle strength, and lower limb muscle strength and endurance were related to cardiopulmonary endurance in elderly inpatients with COPD. Methods This was a cross-sectional study using a systematic sampling of older inpatients. Data of demographic characteristics such as age, gender, and disease severity were collected, and body mass index was calculated. Degrees of dyspnea were assessed by the modified Medical Research Council Dyspnea Scale. Respiratory muscle strength was reflected by the maximal inspiratory pressure and the maximal expiratory pressure. Lower limb muscle strength and endurance were assessed by a handheld dynamometer and a 30-second sit-to-stand test, respectively. Finally, cardiopulmonary endurance was assessed by a 6-minute walk test. Results A total of 83 older COPD inpatients participated. The mean age was 74.01 ± 6.93 years. Cardiopulmonary endurance was associated with age, COPD severity, dyspnea, respiratory muscle strength, lower limb muscle strength, and endurance. Predictors of cardiopulmonary endurance were disease severity, dyspnea, and lower limb muscle endurance. These predictors explained 53% of the variance in cardiopulmonary endurance in older inpatients with COPD. Discussion Cardiopulmonary endurance of hospitalized older adults with COPD should be strengthened by improving conditions of disease severity, dyspnea, and lower limb muscle endurance.

A Retrospective Study of Diaphragmatic Breathing Training Combined with Discharge Care Bundles in Patients with Chronic Obstructive Pulmonary Disease

“…Besides, we need a large number of subjects to verify our findings. Furthermore, fatigue is one of the most disabling symptoms of COPD [ 44 ], and COPD was reported to result in poor cardiopulmonary endurance [ 45 ], indicating fatigue level and cardiopulmonary should be taken into consideration in future analysis. The explanations of abbreviations in this study have been listed in Supplementary Table 1 .…”

Performance-based outcome measures to assess functionality in hospitalised patients with COPD exacerbations: a systematic review of the measurement properties

“…In general, most of the studies evaluated the validity of the instruments, mainly by hypothesis testing [ 27 – 30 , 32 – 35 , 38 ], two studies evaluated reliability [ 36 , 39 ] and only two studied responsiveness [ 29 , 37 ]. Results of the measurement properties are presented in table S3 , while results related to COSMIN methodological quality of the studies and measurement properties are shown in table 2 .…”

“…Results of the measurement properties are presented in table S3 , while results related to COSMIN methodological quality of the studies and measurement properties are shown in table 2 . Some studies had a purpose other than assessing instrument validity [ 28 – 30 , 33 , 38 ]; however, our review team reached a consensus to include studies in which assessing the measurement properties of instruments was not the purpose of the study but still included data relevant to analyse measurement properties. Results of these analysis and the hypotheses formulated by the review team are presented in table S3 .…”

Health benefits of short Taichi Qigong exercise (STQE) to University Students’ core strength, lower limb explosive force, cardiopulmonary endurance, and anxiety: A Quasi experiment research

“…[8] Cardiopulmonary endurance is an individual's ability to maintain long-term exercise or physical activity without tiring; it also refers to the heart's and lungs' ability to deliver oxygen to working muscles during continuous exercise. [9,10] Lower limbs explosive force is characterizing muscular work in a short time and grants the largest acceleration to the organism via fast muscular effort. [11][12][13] Anxiety represents the most common psychological disorder for young adults, it includes a series of negative disorders (phobia, panic, social anxiety, and so on).…”
