Abnormal C-reactive protein alone, without other laboratory abnormalities and the typical clinical features of an infarction, is not sufficient to diagnose an infarction.
C-reactive protein is an acute time-phase reactive protein synthesized by the liver and widely present in serum and other body fluids. Its elevation can be seen in septic infections, tissue necrosis (myocardial infarction, severe trauma, major surgery, burns, etc.), acute rejection of organ transplants, and malignant tumors.
C-reactive protein can also be used to identify bacterial and non-bacterial infections, with the former elevated and the latter not. It can also be used to identify active and inactive phases of rheumatic fever, with the former being elevated and the latter not.
Therefore, when abnormal C-reactive protein is found alone, it is not sufficient for the diagnosis of infarction. If there is a combination of pain in the precordial region, accompanied by agitation, sweating, fear, chest tightness or a sense of dying, then an infarction is highly suspected, and the diagnosis can be made by combining with relevant tests such as cardiac enzyme profiles and electrocardiograms.
If you feel unwell, you should consult a doctor promptly and follow the doctor’s instructions.
