§ Logistic Euroscore: a formula used to predict the risk of death after a cardiac operation [16].
Abbreviations: COPD, chronic obstructive pulmonary disease, EF: ejection fraction, FEV1: forced expiratory volume in 1 second, FVC: forced vital capacity, GERD: gastro-esophageal reflux disease, MI: myocardial infarction, PCI: percutaneous coronary intervention, PMR: polymyalgia rheumatica, eGFR: estimated glomerular filtration rate.
