<qa>  What is the hsCRP at baseline?A total of 40cc blood sample collection in plasma 20cc and serum 20cc will be collected at each echo study, and will be processed and aliquotted within 2 hours at the GCRC core lab. Biomarkers of interest include: 1 plasma B-type natriuretic peptide at every visit, 2 cardiac troponin T at baseline, 3 high-sensitive C-reactive protein hsCRP at baseline, will be sent to the clinical laboratory for analysis. Extra blood will be collected at every visit and stored in -80F freezer for other research-based novel biomarkers, all subject to availability of supplementary external research funding.
