Compared with patients without cardiac injury, those with cardiac injury had lower lymphocyte count, and higher levels of coagulopathy and inflammatory biomarkers [prothrombin time (PT), activated partial thromboplastin time (APTT), C-reactive protein (CRP), procalcitonin (PCT) and interleukin 6 (IL-6)]. The gene discussed is CRP; the disease is blood coagulation disease.
