Categorical variables are represented as n (%); continuous variables are represented as mean (standard deviation) unless noted as median (Q1=quartile 1, Q3=quartile 3). Abbreviations: CNS = central nervous system; NT-proBNP= N-terminal prohormone of brain natriuretic peptide; hs-troponin T = high sensitivity cardiac troponin T; ADI = area deprivation index; BMI = body mass index; sCr = serum creatinine; eGFR = estimated glomerular filtration rate, mmHg = millimeters of mercury; Q1 = quartile one; Q3 = quartile three; FVC = forced vital capacity; FVC/FEV1 = Forced vital capacity to Forced expiratory volume in 1 second ratio.
