In contrast, arrhythmia, other diseases, FEV1, mean corpuscular volume, BMI, mean corpuscular hemoglobin concentration, albumin, C reactive protein, smoking duration, hematocrit, aspartate aminotransferase, percentage VC, and duration of smoking cessation were unlikely to predict rapid decliners (see Supplementary Table 2). This evidence concerns the gene ALB and cardiac arrhythmia.
