The role of electrocardiography (ECG) in predicting mortality patients with chronic obstructive pulmonary disease (COPD) has not been sufficiently established. Research question: Is a normal ECG associated better prognosis than an abnormal COPD? parameters were assessed enrolled the Czech Multicenter Database COPD. We ECGs from baseline (August 2013) until December 31, 2019, or death. primary endpoint was 5-year overall survival depending on findings. A total 300 subjects study and 143 died...

This randomized controlled trial evaluated the effectiveness of two home-based, stand-alone inspiratory muscle training (IMT) modalities - flow-resistive loading with biofeedback (IRFL) and mechanical threshold (MTL) compared to a sham MTL group for improving performance functional exercise capacity in COPD patients. Thirty-six patients trained at home 8 weeks under remote monitoring. Primary outcomes included assessed via Test Incremental Respiratory Endurance (TIRE), capacity, lung...

Measurement of ventilatory efficiency, defined as minute ventilation per unit carbon dioxide production (VE/VCO2), by cardiopulmonary exercise testing (CPET) has been proposed a screen for hyperventilation syndrome (HVS). However, increased VE/VCO2 may be associated with other disorders which need to distinguished from HVS. A more specific marker HVS CPET would clinically useful. We hypothesized control during is abnormal in patients HVS.Patients who underwent years 2015 through 2017 were...

This study investigated an alternative home-based cardiac telerehabilitation model in consideration of the recommendations for COVID-19 quarantine people diagnosed with coronary heart disease (CHD). We hypothesized that using a 200 m fast walking test (200 mFWT) and would create effective rehabilitation (CR) intervention could improve cardiorespiratory fitness. Participants (n = 19, mean age 60.4 ± 9.6) 8-week performed regular physical exercise at target rate zone determined by calculations...

Background: Respiratory parameters are important predictors of prognosis in the COPD population. Global Initiative for Obstructive Lung Disease (GOLD) 2017 Update resulted a vertical shift patients across categories, with category B being most populous and clinically heterogeneous. The aim our study was to investigate whether respiratory might be associated increased all-cause mortality within GOLD patients. Methods: data were extracted from Czech Multicentre Research Database, prospective,...

Introduction Ventilatory efficiency (V E /VCO 2 slope) has been shown superior to peak oxygen consumption (VO ) for prediction of post-operative pulmonary complications in patients undergoing thoracotomy. V slope is determined by ventilatory drive and ventilation/perfusion mismatch whereas VO related cardiac output arteriovenous difference. We hypothesized pre-operative predicts cardiovascular lung resection. Methods Lung resection candidates from a published study were evaluated post-hoc...

Abstract Background Physical activity is a crucial demand on cystic fibrosis treatment management. The highest value of oxygen uptake (VO 2peak ) an appropriate tool to evaluate the physical in these patients. However, there are several other valuable CPET parameters describing exercise tolerance (W peak , VO 2VT1 2VT2, 2 /HR etc.), and helping better understand effect specific (V E V T D /V etc.). Limited data showed ambiguous results this improvement after CFTR modulator treatment....

Background: Patient adherence to an inhaled medication application technique (A-ApplT) represents a major health-care issue in patients with chronic obstructive pulmonary disease (COPD). However, there is lack of studies evaluating this thoroughly. The aim our study was introduce universal easy-to-use method assessing the A-ApplT moderate very severe COPD individuals. Methods: Czech Multicenter Research Database (COPD CMRD), large observational prospective study, used as source clinical...

BackgroundCardiopulmonary exercise testing parameters including ventilatory efficiency (VE/VCO2 slope) are used for risk assessment of lung resection candidates. However, many patients unable or unwilling to undergo exercise. VE/VCO2 slope is closely related the partial pressure end-tidal carbon dioxide (PETCO2). We hypothesized PETCO2 at rest predicts postoperative pulmonary complications.MethodsConsecutive candidates were included in this prospective multicenter study. Postoperative...
