Angiotensin-converting enzyme (ACE) I/D corrected serum ACE activity and severity assessment of community-acquired pneumonia.

abstract：BACKGROUND:Cardiac troponin T (cTnT) has been reported to be a predictor of stroke outcome. We hypothesized that the high-sensitivity cTnT (hs-cTnT) assay is superior to its previous assay generation for stroke outcome prediction. METHODS:cTnT was measured on emergency department admission in 60 consecutive patients (...
