Meanwhile, cardiac troponin was significantly elevated in those patients compared to healthy subjects (0.17 vs. 4.82 ng/ml, respectively). However, the parasympathetic biomarkers (plasma and RBC cholinesterase activity) did not differ substantially between patients and healthy controls (0.83 vs. 0.92, P > 0.05 and 1.36 vs. 1.37, P>0.05, respectively). Serum troponin I was more valid than chromogranin A in differentiating acute coronary syndrome from healthy subjects. The area under the curve for troponin I was (0.989) compared to ( 0.724) for chromogranin A. Furthermore, plasma chromogranin A but not plasma and RBC cholinesterase activity was significantly increased in fatal cases compared to nonfatal patients (1166.68 vs. 3435.64 ng/L).</p> <p><strong>Conclusion:</strong> Plasma chromogranin A was less effective than troponin I in detecting acute coronary cases; however, it can be helpful as a prognostic marker in those patients. Parasympathetic biomarkers were not appreciable in diagnosing and detecting risky patients. </p>}, number={1}, journal={Journal of Contemporary Medical Sciences}, author={Abdi, Zana and Hussein, Hishyar MS Garmavy and Rasool, Suzan}, year={2023}, month={Feb.} }
