Some patients had chronic coronary syndromes and acute coronary syndromes (in which LDH, CKMB, troponin, and CRP levels increased), chronic heart failure and acute heart failure (with an increase in cardiac enzymes as a result of myocardial injury [23]), VTE (with an increase in D-dimer levels as well as cardiac enzymes [24]), acute inflammatory conditions such as exacerbations of COPD or septic conditions (with an increase in CRP, as well as D-dimer or ferritin [25,26,27,28]), and chronic liver disease (in which LDH, ferritin [29], and D-dimer levels can increase [30]). Here, CRP is linked to chronic obstructive pulmonary disease.
