In comparison to patients with normal copeptin levels , patients with elevated levels were older , had more pre-existing cardiac and non-cardiac disorders , more silent cardiomyocyte injury and increased haemodynamic stress as quantified by levels of high-sensitivity cardiac troponin T ( @ ng/L ( @-@ @ ) vs @ ng/L ( @-@ @ ) ) and B-type natriuretic peptide ( @ng/L ( @-@ ) vs @ng/L ( @-@ ) ) ( both p < @ ) , more electrocardiographic abnormalities , more often an adjudicated diagnosis of gastroesophageal reflux or bronchitis/pneumonia and higher @-year mortality ( HR @ , @ % CI @ to @ ) .
